Structure particularly for transmitting control signal for aircraft

[Detailed Description of the Invention]

[Industrial Application] the passivity currently formed from the branched light pipe which the servo unit which operates operation wings has connected with the Gyratory function part which this invention transmits [ function part ] a digital lightwave signal and generates operation instructions -- a conductor -- a system is equipped and it is related with the control-signal-transmission device for airplanes which processes and transmits a digital control signal. [Description of the Prior Art] In order to make operation operation transmit to a rudder from a pilot in an airplane for example, generally it is common knowledge to use a mechanical apparatus like combination, such as a wire rod, stick material, the axis of rotation, or this. According to condition of use, devices, such as this, are supported by oil pressure or electric drive. a large-sized airplane -- servo control -- line intermediary To have -- things are also common knowledge. When this kind of control is being used, in order to connect between predetermined rudders, the following operating procedure is always specified, for example. That is, an elevator is certainly operated symmetrically. A rudder is operated asymmetrically. A flap is certainly operated symmetrically. Therefore, when one rudder breaks down, the fault referred to as being unable to use it produces the remaining rudders by a case in order to maintain maneuverability drivability. If it takes into consideration from a viewpoint for military affairs, other faults of the above-mentioned machine control will arise from the ease of damaging. For this reason, the electric servo control which transmits a control signal, for example with a passive conductor like a coaxial cable is used. In this case, each circuit of operation is made multiplex (4-fold [ for example, ]) including the cable which leads to an actuator. Therefore, even if three of attached cables are damaged by a bullet etc., a circuit of operation still functions. However, there is the following weak point also in this idea. - This kind of device is weak to electromagnetic blocking space (a thunderbolt, a short circuit). - Because of a time delay and reflex action, every time the Net-ized network does not equip a functional circuit element at a together joining point, it is unrealizable. - Wiring is realizable only in the form of the rope relevant to a function for the above-mentioned operation. In 4-fold design, this means installing 4-fold cable to each actuator. - Wiring of this gentleman type will become heavy conductor weight, if a cable with little attenuation is used. In order to control a ship, an airplane, or an industrial process using the light pipe which constitutes a data bus system from a magazine "electro Nik praxis" ("Elektronikpraxis", Vol.11, 1979, p.34), it is already publicly known to introduce this conductor. A data bus is a conductor which transmits information to in a narrow sense, and it has connected all the related parts to this conductor. The above-mentioned information can constitute this kind of system also from a star-shaped bus also as a T type bus. In the case of a star-shaped bus, the connection conductor of all the related parts is concentrated at the star-shaped joint machine. In the case of T type bus, each related part is connected via T type joint machine at the data bus. Although the advantage over weight and tolerance is expectable about applying a light pipe to operation of an airplane, for example, there is a fault said [ having connected each related part to the remaining systems only via one conductor also by the design concept of a star-shaped bus or T type Buzz's design concept and ]. Therefore, if this conductor breaks down, a result in which the function of the related part which is involving also breaks down will be brought. Since this is not using the - third component in operation of an airplane when a corresponding conductor breaks down, it is local failure, for example. - If it carries out by accident, it means that an operation function breaks down fatally. [Problem(s) to be Solved by the Invention] So, when the subject of this invention operates without a lagged effect, reflection, and disturbance by an electromagnetism turbulence place to the device which transmits the control signal for airplanes and a control element is damaged, it is in providing the passive conductor circuit network which performs new control currently programmed beforehand. [Means for Solving the Problem] The above-mentioned subject has been solved by the control-signal-transmission device for airplanes which forms one network which light pipes 11 and 12 multiplexed in the shape of meshes of a net by this invention. Other advantageous constitution of this invention is given to the remaining claims. [An operation and an effect] If a device by this invention is used, compared with solution etc. which combined machinery, oil pressure, electricity, or it, reliability which acted as Kougami remarkably to failure will be attained. Based on this invention, combination of inclination with new operation wings can be performed under a dangerous fixed situation. Therefore, when a rudder breaks down, the maneuverability drivability of an airplane can be secured. Especially composition by the 11th paragraph of a range of an application for patent is advantageous. By this composition, energy supply of a device is raised to the same level as the remaining components to a grade of the reliability of a device. [Example] Below, based on a mimetic diagram, this invention is explained in detail. The transmission equipment of the control signal for airplane F is shown in Drawing 1. There are the usual operation wings, i.e., two elevators 1, 1', one rudder 2, two slow speed ailerons 3 and 3', two rapid ailerons 4 and 4', taking-off-and-landing flap 5 and 5', leading edge flap 6 and 6', and tail 7 in this airplane F. Also in it, drive 8, 8', and operation function part 9 are allocated in airplane F. In this case, control lever 9a and the pedal are shown in this mimetic diagram. The multiplex circuit network of the light pipe currently formed mainly from a plurality of signal processors 10, derivatives 11, and horizontal conductors 12 is among the transmission systems which transmit a control signal. This network is connected to addressable servo unit 14. In this case, together joining point 13 is formed from publicly known branching used as the star shape or T type joint machine, for example. Operation function part 9 is constituted so that the digital lightwave signal equivalent to operation instructions may be outputted. Servo unit 14 allocated around this network operates the device which changes the inputted lightwave signal into control movement. the lightwave signal corresponding to [ to this unit, detect the moment position of operation wings, for example, and ] this -- length -- there is a device outputted to conductor 11. signal processor 10 and length -- data communication between the peripheral equipment connected via conductor 11 is performed periodically. That is, signal processor 10 outputs the information signal addressed the fixed appeal cycle, for example to servo unit 14. This servo unit answers using the information signal which addressed the above-mentioned signal again. The data communication performed here is prescribed by the wording of a telegram of the fixed word size. Wording of a telegram, such as this, is made digital frequency abnormal conditions, and is put on the carrier frequency. In that case, finally the lightwave signal has received the amplitude modulation according to a carrier frequency. Therefore, very high reliability can be acquired to external invasion light. Since the transmission way is made into the shape of meshes of a net, the course of a large number which a signal cuts signal processor 10 is followed, the above-mentioned servo unit 14 is reached, and the reliability of a system is further raised. The illustrated system is made into Mie and formed. namely, the width corresponding to the body, a wing, and A page wing -- three length which has conductor 12 -- conductor 11 is allocated, a rudder, operation wings, etc. hit and there are three servo units 14. There is the main control circuit of all the devices in signal processor 10. It is constituted by Mie in order that this unit may also raise reliability. The circuit of signal processor 10 which comprises mixer 15 and three information systems 16, 17, and 18 is shown in Drawing 2. Mixer 15 is connected to primary network 20 made from a light pipe via light pipe 19 constituted in Mie. Three outgoing ends of mixer 15 are connected to one of the information units 16~18, respectively. furthermore -- there is connection light pipe of three 16a~18a in each unit 16~18, respectively -- conductors, such as this, -- length -- conductor 11 and width -- it has connected with network 24 which comprises conductor 12. Mixer 15 is charge intermediary To have about the duty to process the digital lightwave signal inputted, for example from a control lever, to evaluate another information logically, and to further transmit the above-mentioned lightwave signal to information system 16~18. If the signal which is equivalent to a predetermined target altitude, for example, and the signal equivalent to the survey altitude outputted from altimeter 22 are introduced into mixer 15, this mixer 15 will form the difference signal used in order to set up a target altitude, and will input this difference signal into network 24 via information system 16~18. The wording of a telegram addressed to servo unit 14.01 of the elevator is received from this Unitsu, and it transposes to the inclination of a rudder according to it, and returns an airplane without a pilot's participation to a predetermined fight level. Similarly, mixer 15 compares with predetermined route and desired value the route and actual measurement outputted from aviation device 23. The difference signal which arises at this time is changed into the control instructions addressed to servo units 14.03 and 14.04 of aileron 2 of servo unit 14.02 of aileron 2, and is introduced into the above-mentioned servo unit via network 24 via information system 16~18. Servo units, such as this, carry out the intermediary response also of the inclination of an aileron which gives required route amendment. The display operation equipment which is connected to mixer 15 via primary network 20 and which is not illustrated is used in order to carry out the graphical representation of a Eye frequency value and the actual measurement using the symbol of Steady. If this device is switched to manual operation, comparison of the Eye frequency value by a mixer and an actual measurement is no longer performed, and the control instructions inputted via primary circuit 20 will be made into corresponding wording of a telegram, and will be introduced into the above-mentioned servo unit. The control function section 9 which outputs control instructions, for example, a control lever, the pedal, the control wheel, etc. are connected to primary circuit 20 via the light pipe constituted in Mie. The mission of information system 16~18 controls by the above-mentioned progress the data communication which carries out the inside of mixer 15 conventionally a fixed cycle, and is preparing the addressed instructions or the appeal wording of a telegram by it according to it. The principle figure of photovoltaics 25 for position perception of control lever 9a which functions as a signal oscillator is shown in Drawing 3. This device comprises circular holding part 25a which mainly formed euphotic diode 26 in the inside, and diodes, such as this, are connected to the input edge of coding matrix 27, respectively. Segment portion 29 rotated around fixed point 28 makes that inner side counter, and it has allocated in it, and this fixed point 28 forms while [ circular / = ] one field of rotary part 29 has center 28 with holding part 25a in holding part 25a in accordance with the center of the inner side outline of holding part 25a. Light emitting diode 30 is allocated in the circular edge surface of rotary part 29, and the light emitted from diodes, such as this, is directly received by diode 26. Light emitting diode 30 is connected to change matrix 31 which has received supply of current from the network on a plane. However, three buffer batteries 32, 33, and 34 are allocated. Change matrix 31 outputs the electric pulse used as the predetermined pattern, and light emitting diode 30 emits a fixed digital lightwave pulse by it. Flexible region 29 is connected to the control lever so that a fixed relation may be followed at movement of Keep it control lever 9a. In this case, euphotic diode 26 receives the receiving item corresponding to each position of a control lever. This lightwave signal is changed into a digital lightwave signal by coding matrix 27, and appeal is continuously carried out by mixer 15. Failure of the power supply of the diode depending on a network on a plane will supply the energy according to it from buffer battery 32~34. If more diodes than per unit of a curve are attached, a signal generator will be more highly precise and will operate. If flexible region 29 is driven with the conversion gear of the method of Public, accuracy will improve. Even when it breaks down by a logic circuit while three light emitting diodes 30 operated, reading by a coding matrix is still exact. According to this invention, other operation functions, such as a pedal and an operation theory, can be equipped with photovoltaics 25 of the above-mentioned method. If luminescence and a euphotic diode are replaced, other modification kinds of photovoltaics 25 will be given. The block circuit diagram of power Shimmirator 35 is shown in Drawing 4. This kind that simulates the power of a rudder of device is publicly known in itself, and, in many cases, has put the foundation on the very complicated mechanical transfer device. The device shown here operates electromagnetically and is controlled via a light pipe. Power Shimmirator 35 mainly comprises control unit 36, electronic Shimmirator unit 37, and electric motor 38. The above-mentioned mixer 15 outputs the signal equivalent to the flying speed addressed to power Shimmirator 35 via the light pipe. Signals, such as this, are alternatively received with control unit 36, and it further introduces into electronic Shimmirator unit 37 as an electric digital signal. This Shimmirator unit outputs an electric predetermined output to motor 38 according to inclination of flying speed and a rudder based on the functional equation by which the fixed program was carried out about the airplane. Torque M to which this motor corresponds via axis 38a by a state of rest_dTransmitting, this torque acts on control lever 9a directly, for example, corresponds to the power of a rudder well, and gives the power which can be perceived to a pilot. Direction of torque will be reversed if control lever 9a passes a neutral position based on the program which Shimmirator unit 37 was made to memorize. The signal inputted into mixer 15 according to flying speed is drawn via an analog-to-digital converter by the measurement result of the Pitot tube which is not illustrated, for example, is made into a digital lightwave signal via an addressable control device, and is supplied to primary circuit 20. The internal circuit of mixer 15 which has two connecting units 39 and 40 which are attached to one control lever 9a with three central operation units 41, 42, and 43, respectively is shown in Drawing 5. One memory machines 44, 45, and 46 are allocated in operation units, such as this, respectively. There is a connecting unit which is not illustrated to each function which outputs control instructions in mixer 15. There are perpendicular standard circuits 47, 48, and 49 and level standard circuits 50, 51, and 52 in mixer 15 outside it per memory machine. The light pipe is used in order to connect power Shimmirator 35 with control lever 9a. Each functional unit of mixer 15 is mutually connected by the electric lead corresponding to Drawing 5. Connection with information system 16~18 is similarly made via an electric lead. For example, the coded signal which is outputted from control lever 9a reaches connecting unit 39 which mainly comprises an amplifier and a numerals converter. Here, the above-mentioned signal is amplified, or it codes, and supplies the data bus inside the mixer linked to central operation units 41, 42, and 43. The signal of control lever 9a is connected to the control lever, and the priority circuit in a connecting unit operates a control lever, as long as it is held until priority is based on manual operation. With memory machines 44, 45, and 46, the data equivalent to standard circuit 47~49 and the survey position of the airplane outputted from 50~52 is memorized, and it compares mutually via operation unit 41~43. In this case, data congruous in many operation processing units 41~43 is accepted to be the right things. The operation unit which has the information from which it separated regards it as an error, and it prevents it via the data bus inside a mixer. The above-mentioned operation is performed by the special error code signal. Operation unit 41~43 is also a unit which carries out operation required for the above-mentioned automatic flight operation. The corresponding processor is known for the sign of PDP11/70, for example. Corresponding to Drawing 1, the whole device uses three signal processors 10 and three mixers 15, and this is raising reliability. The block circuit diagram of a photoelectrical information system which is allocating in the inside of processor 10 information units 16, 17, and 18 constituted in Mie by Drawing 2 is shown in Drawing 6. There are three processors 53, 54, and 55 which have three receivers 68, 69, and 70 mutually connected with three memory machines 56 and 57, 58 or 3 numerals abnormal-conditions machines 59 and 60, 61 or 3 recovery decoders 62 and 63, and 64 or 3 transmission machines 65, 66, and 67 in the illustrated system. The principal part of transmission machine 65~67 is a laser diode which outputs a lightwave signal to network 24, respectively. A receiver is formed from one silicon photo-transistor on substance, respectively, and this transistor works as a photo acceptance unit to the lightwave signal inputted via network 24, and changes a lightwave signal into a mind telegraphic communication item again. The illustrated information system comprises three branching which operates by a parallel circuit in order to raise reliability. In order to explain operation, branching which comprises processor 53 which first has left-hand side branching 56, i.e., memory machine, numerals abnormal-conditions machine 59, recovery decoder 62, transmission machine 65, and receiver 68 is considered. This circuit controls the data communication between network 24 and memory machine 15, and the oscillator in processor 53 functions as a clock generation machine. The electric signal which reaches processor 53 from mixer 15 is introduced into numerals abnormal-conditions machine 59. Inside a coding portion, a data message is changed into the language and address structure related to the circumference from the structure related to a processor. Subsequently, this wording of a telegram passes along a modulation part, carries out the frequency modulation of this wording of a telegram to a subcarrier with high frequency, and carries it here. Subsequently, the contents of corresponding pure data are returned by recovery in the middle stage, and are not put on other fixed subcarriers by amplitude modulation. Thus, the signal which arose is amplified in transmission machine 65, and a laser diode is supplied. This laser diode outputs the lightwave signal similar to diode current to network 24. in the opposite direction, Optical signal has been changed into the amplitude modulation electricity signal since an ON intermediary via network 24 by the photo-transistor received and incorporated with receiver 68. Subsequently to recovery decoder 62, this signal reaches. There is a data message of structure related to a processor in the outgoing end of this recovery signal machine, and operation processing of this wording of a telegram is again carried out by processor 53. Two branching of everything but a system performs the operation same [ same cycle ], and a synchronization pulse outputs it from the clock generator of processor 53. If this clock generator breaks down, branching of the illustrated left-hand side will stop automatically, and the next clock generator will control a synchronization. Information systems 17 and 18 of Drawing 2 usually synchronize by processor 53. A corresponding synchronization pulse is outputted via network 24. The block circuit diagram of servo unit 14 which operates elevator 1 which has a machinery portion and an electric portion, for example is shown in Drawing 7. A machinery portion mainly comprises driving cylinder 71, connecting bar 72, and two servovalves 73. There are two servo amplifiers 79 and 80, processor unit 81, abnormal-conditions machine 82, demodulator 83, transmission machine 84, receiver 85, position converter 88, memory machine 78, and power supply 88 in an electronic portion. This is connected mutually. If functional units, such as this, are allocated in the electronic circuit room which is formed mainly by an integrated circuit and is in the case of driving cylinder 71, they are advantageous. Thus, driving cylinder 71 which equipped the electronic portion forms new Up of a form, and It was servo unit 14 for which it waits, it returns to this servo unit with pressurization lead pipes 74 and 75 of oil pressure, and there are contact button 89 for current supply and two light pipe contact buttons 90 and 91 out of lead pipes 76 and 77. The lightwave signal which inputted via light pipe 11 and was addressed by driving cylinder 71 from information systems 16, 17, and 18 is changed into an electric signal by receiver 85, and is introduced into demodulator 83. The above-mentioned demodulator inputs this wording of a telegram into processor unit 81 which controls the decoder which pulls out the original data message from this signal, and it has incorporated. The above-mentioned decoder changes wording of a telegram into a peculiar appeal cycle, and connects it with an internal data bus. Possible various operation programs of driving cylinder 71 are stored by memory machine 87. In order to control servo amplifiers 79 and 80 which carry out electric control of the servovalve 73, based on this wording of a telegram, a fixed program is called from memory machine 87. This valve controls receipts and payments of operation oil to give starting of movement which is in agreement with the program which connecting bar 72 called to elevator 1 (not shown). Memory machine 87 can be formed as a semiconductor or a magnetic valve memory machine. An addressable program is made into urgency, slow speed, a line type, and the function that gives inclination of a non-line type rudder, and is memorized. Various control conditions can be satisfied with the memorized function. For example, inclination of a rudder can be united with each flying speed. It has a predetermined program for emergencies and can compensate failure of an important rudder. For example, considering it as a balance is also considered by leaning ailerons 3 and 4 or 3' which is inside the bend which gave asymmetrical inclination to the elevator for failure of aileron 3, and maintained the balance, or meant failure of rudder 2, and 4' to Tendency. Other new possibilities based on this invention have a side wind of one side which acts on a wing, for example in the point which leans the aileron of one side rapidly and is compensated. On the other hand, the aileron nearest to the place where load is added is operated. An operation of this kind is introduced by the signal of the accelerometer of the usual method formed, for example in wings. The above-mentioned example shows what uses this device in the case of the merely corresponding program, and exerts an advantageous operation on it. Drive generator 78 outputs the signal corresponding to each position of connecting bar 72 towards position converter 86 which is an analog-to-digital converter. The signal outputted from the converter of this is inputted into processor unit 81, and is used for controlling the program which this unit carries out here. A data message corresponding per appeal reaches information systems 16, 17, and 18 one by one via abnormal-conditions machine 82, transmission machine 84, and light pipes 11 and 12, and controls operation of servo unit 14. Memory machine 87 has various operation programs performed by driving cylinder 71 (or for example, electric servo motor) according to the above-mentioned matter, and it is used in order to supervise a cylinder based on the signal simultaneously outputted from a position transducer, i.e., drive generator 78. This kind of memory machine is also called "intelligence memory machine." As processor unit 81, 8080 of the device known well and Intel (INTEL) can be used. The block circuit diagram of display operation equipment 92 is shown in Drawing 8. There are operation unit 93, electronic image unit 94, picture screen 95, keyboard 95a, numerals machine 96, transmission machine 97, decoder 98, and receiver 99 in this device. Transmission machine 97 and receiver 99 are connected to primary network 20 via the light pipe. For example, operation data is inputted into primary network 20 via Al Fernie Yumerituku keyboard 95a which operates in ASCI and code (U.S. standard code for information exchange). The selection key which attached the sign according to it is used to a fixed form of operation. Here, a basic motion form like manual control (MANOP), semiautomatic control (SEMOP), or automatic control (AUTOP) can be chosen, for example. In this case, there is a mission which carries out signal processing so that mixer 15 may be reached via a light pipe via numerals machine 96 and transmission machine 97 in the form of the data message in which the output signal of key 95a carried out appeal in an operation unit. Screen 95 is connected to operation unit 93 via electronic image unit 94. There are a signal generator and a numerals conversion matrix which are used for the usual image display in image unit 94. This kind of circuit is publicly known from Klein, "Mikrocomputersysteme", Francis Verlag, Munchen, 1979, and 2Auf.S.32. Screen 95 is formed as a semiconductor picture screen, and it is used in order to display amendment of the control which displays the actual position of airplane F and which was sake [ control ] and carried out. For the processing which indicates the information on a position and a route by symbolic here, the signal generator of image unit 94 is used in order to create the Al Fernie Umerik sign in the ASCI code. Since a numerals conversion matrix controls the point matrix place of picture screen 95, it changes the digital signal in the numerals of a signal generator into a corresponding display. The whole arrangement can use the three above-mentioned display operation equipment 92. In that case, the figure and I got it operation disposal which were displayed are usually completely a different Noodle thing because of the different Noodle mission of an operation member, respectively. Even in this case, the illustrated circuit can be programmed and changed according to it. The block circuit diagram of dialog device 100 which the significant composition of this device produces is shown in Drawing 9. This dialog device 100 comprises conversation-analysis unit 101 linked to a microphone, and the conversation and the synthesizer unit 102 linked to a speaker. Dialog device 100 communicates with operation unit 93 of display operation equipment 92 of Drawing 8, and makes an above device and the dialog of an operation member perform. In this case, the code word verbally inputted via a microphone is recognized based on the syllable evaluation which this unit was made to memorize in a linguistic analysis unit, is made into the corresponding digital telegram, and it inputs into operation unit 93. This This can be performed using what is called a PROM language decoder (PROM= program read-only memory machine). Conversely, important information can be outputted via a speaker to an operation member. In this case, language composition is performed by the PROM language decoder within unit 102. The wording of a telegram outputted from operation unit 93 is decoded, and the above-mentioned language decoder compounds it in the output language according to it based on the memorized syllable evaluation, and outputs it to a speaker via the output amplifier which is not illustrating this voice frequency signal. This kind of a language code machine or a decoder is publicly known in itself, for example, is indicated as an example of application after 1980 or 14 magazines "electro Nik" (Elektronik) and 54 page. The remarkable improvement in reliability is attained by application of automatic recognition and removal of the fault by the light pipe art by this invention, the digital technology on the basis of a microprocessor, and a logic circuit in the above-mentioned main part of a device. When driving this device in the source of energy supply of the usual method, the reliability attained decreases sharply. Therefore, if the idea of this invention is advanced, energy supply of a device will be performed by the equivalent energy supplying device. According to this, the principle circuit of the energy supplying device is shown in Drawing 10. The device by the side of the airplane which transmits a control signal has received supplies from four different energy sources. That is, an energy source is airplane drive 8, auxiliary turbine 112, battery 128, or prograde motion turbine 120. Dynamo 104 and hydraulic pump 105 have connected with the axis of a drive inside engine nacelle 103. Servo unit 14.09 or the hydraulic pressure supply of 14.10 returns with pressurization lead pipe 107, and is performed via lead pipe 108. The electric output of dynamo 104 is connected to the pressurization lead pipe so that the metal circle pipe of pressurization lead pipe 107 may be simultaneously used as an electric energy lead. The opposite electrode of the dynamo is connected to the grand line. Measurement / change unit 106 is connected to dynamo 104 and pump 105 in network 24 via three transmission units 110 which carried out multiple connection on the other hand by one side. Auxiliary turbine 112 is connected with hydraulic pump 114 different from another dynamo 113. Since the input edge of dynamo 113 is connected to pressurization lead pipe 118 via lead 117, pressurization lead pipe 118 is simultaneously used as an electric energy lead also here. Return is performed via lead 116. Return of electricity is performed via a grand line. Measurement / change unit 115 is connected to auxiliary turbine 112, dynamo 113, and pump 114 via transmission unit 110 in network 24 again on the other hand by one side. Battery 128 can be used as another energy source (on a plane). This battery 128 is supplying electric power to electric motor 129 connected with hydraulic pump 130. It connects with pressurization lead pipe 132 also here, and this is being simultaneously used for battery lead 133 as a power supply conductor. Return of electricity is performed via a grand line. Return of oil pressure is performed by lead pipe 134. Measurement / change unit 131 is connected to electric motor 129, pump 130, and switch 136 via transmission unit 110 in network 24 again on the other hand by one side. As another energy source, prograde motion turbine 120 is provided and this can be driven by prograde motion motor 123 with collecting device 119 in a relative wind. Collecting device 119 comprises dynamo 121 and hydraulic pump 122, output lead 126 of the dynamo is connected to pressurization lead pipe 125, and this lead pipe is operating also as a power supply conductor. Return of oil pressure is performed via lead pipe 127. Return of electricity is performed via Granland Line. Since it has connected with optical textiles network 24, inspection unit 135 allocated in arbitrary positions carries out digital communication of this network with the above-mentioned measurement / change unit. In operation without disorder of usual, the source of power of electricity and oil pressure is supplied with dynamo 104 and pump 105 which were formed in Nasser 103. In this case, the appeal of dynamos, such as electricity, temperature, and pressure, and the typical performance data at that time of a pump is carried out by the digital wording of a telegram addressed to measurement / change unit 106, and they are compared with the default value memorized in inspection unit 135 by inspection unit 135. the list of priorities which has recognized this failure immediately by the inspection unit, and was memorized when the drive broke down -- therefore, it is connected, the energy source, for example, the auxiliary turbine, of the nearest next. The digital lightwave signal addressed to measurement / change unit 115 reaches transmission unit 110 via network 24, is changed into an electric signal, is identified, and is further introduced into measurement / change unit 115 as a result of the right address. This unit is connected with an auxiliary turbine by receptacle I got it. wording of a telegram, and returns performance data corresponding by appeal to inspection unit 135. If an auxiliary turbine breaks down, this will be immediately identified by inspection unit 135, for example, prograde motion turbine 120 will be connected as nearest energy source. The corresponding signal outputted from inspection unit 135 reaches measurement / change unit 124 via network 24 and transmission unit 110, and this unit starts the change process according to it. Failure of prograde motion turbine 120 will apply battery 128 as an energy source similarly. For example, if the comparatively large power consumption of a control device is taken into consideration, the electric supply to the main systems of an airplane can be guaranteed with this battery only for a short time. However, it should be cautious of for several of these minutes being decisive. In this kind of device, it changes into the usual power supply 115V/400Hz with the converter which naturally is not illustrating the battery voltage of 24V. All the engines are equipped with the dynamo and the pump in the airplane of the multi stage engine. Here, if drive 8 breaks down, before connecting auxiliary turbine 112, other drives 48 will be first applied for electric supply of a control device. The internal principle circuit of inspection unit 135 of Drawing 10 is shown in Drawing 11. This unit comprises three central operation units 137,138 and 139 which have memory machine 140,141,142, respectively. Central operation units 137,138 and 139 are connected to network 24 via photoelectrical information systems 147,148 and 149, respectively. Two MP (microprocessor) selection machines 145,146 are connected to operation unit 137,138,139 via common data lead 151. External memory machine 150 for warning data is connectable with operation unit 137, for example. Since photoelectrical information system 147,148,149 is connected to network 24, inspection unit 135 can carry out data communication with all the functional units of the whole system connected to network 24. Inspection unit 135 operates as follows. Three operation units 137,138,139 are supervised with two MP selection machines 143,144, and MP selection machine 143 usually operates as an appeal cycle determination circuit with operation unit 137 in that case. The inspection unit is normal if an appeal cycle with simultaneous MP selection machine 143 of all the operation units 137~139 is received. If the appeal cycle of one operation unit is not in agreement with the appeal cycle of other two operation units, this operation unit will be intercepted via two MP selection machines 143,144. MP selection machines 143,144, such as this, inspect the same information state as mutual. In this case, if disagreement arises, one of the operation units will take over the inspection of MP selection machine one by one until it is intercepted noting that one of both selection machines has a defect. It has guaranteed becoming higher than the individual reliability of each circuit which the reliability of inspection unit 135 inside should inspect in this way. Inspection unit 135 asks each functional unit of an energy supplying device in the key address attached to this unit. Based on this, the unit which answers outputs the data message addressed to inspection unit 135. It is made the form which performance data coded and the address of this unit is further put into this wording of a telegram. The traced data is compared with the preset value dedicated in memory machine 140,141,142 by the analysis program inside an inspection unit. Thus, it is traced whether the unit made into a problem is normal. When this unit is abnormalities, this unit is separated from inspection unit 135, and is connected with the unit which takes over the function which follows the above-mentioned list. The change instructions corresponding to this are made into the form of the addressed digital photoelectrical sentence, and reach the unit concerned. In this case, communication of the data which keeps company with inspection unit 135 is controlled by photoelectrical information system 147,148,149 a fixed cycle. The address corresponding via the system of the above [ instruction wording of a telegram or appeal wording of a telegram ] is prepared. The internal principle circuit diagram of measurement / change unit 115 of Drawing 10 is shown in Drawing 12. This unit comprises A/D conversion machine 152 and change unit 157. Since transmission unit 110 which has an internal circuit is also shown here, it is effective. This transmission unit comprised numerals machine 153, transmission machine 154, receiver 155, and decoder 156, and this is mutually connected, as shown in the circuit diagram. The example of auxiliary turbine 112 explains the form of measurement / change unit 115 of operation. While auxiliary turbine 112 is operating, by sensor 158, the output voltage of dynamo 113 is measured, for example, and it inputs into A/D conversion machine 152 in the form of the corresponding analog signal. This converter creates a corresponding digital signal and sends this to numerals machine 153. This numerals machine 153 assigns the address of inspection unit 135 to the above-mentioned signal, and now, further transmits Noodle wording of a telegram to transmission machine 154 as it is enough as contents. If the appeal wording of a telegram of addressed corresponding inspection unit 135 is inputted via receiver 155 and decoder 156, sending this wording of a telegram only to transmission machine 154 by horizontal combination 160 will be guaranteed. It has connected with network 24 via light pipes 161 and 162, and transmission machine 154 and receiver 155 make corresponding wording of a telegram the form of a digital lightwave signal, and communicate. By another sensor, turbine number of rotations, the current of a dynamo, and other quantity like oil pressure can be measured, for example, and it can send to this inspection unit 135. If the defect of an auxiliary turbine is detected by inspection unit 135, the wording of a telegram addressed to change unit 157 via network 24 will reach via receiver 155 with interception instructions, and will identify and read this wording of a telegram using decoder 156. Based on this, a decoder sends a corresponding signal to change unit 157. According to the contents of wording of a telegram, change unit 157 separates all the combination of auxiliary turbine 112, dynamo 113, and the airplane provided with pump 114 of operation. In this case, switch 159 which makes dynamo 113 intercept for example may be installed. Network analysis machine 163 linked to a part of optical textiles network 24 is shown in Drawing 13. There are many optical textiles outgoing ends 164 and input edges 165 in this analysis machine, respectively. In order to inspect light pipe 167, together joining point 168 is connected to one of the optical textiles outgoing ends 164 via inspection conductor 166. Together joining point 169 is connected to one of the optical textiles input edges 165 via another inspection conductor 170. It is checked whether it is emitted from network analysis machine 163, it comes out of together joining point 169 with the lightwave signal introduced into together joining point 168, and the lightwave signal introduced into a circuit analysis machine via inspection conductor 170 is equivalent to a normal or unusual light pipe. Although network 24 is very low to an actuating signal, in this, it has large attenuation to an inspection signal, and the attenuation which can be measured certainly needs to arise from a fixed together joining point in the light pipe introduced into the together joining point of another side in it. In this way, the turbulence effect of the next conductor introduced via other together joining points can be abolished. Attenuation of different network 24 to an actuating signal and an inspection signal can be attained by using red for a color different, for example to both signal methods, i.e., an actuating signal, and using green for an inspection signal. When required, it can color and the color dependence of attenuation of a network can raise the material of a light pipe. The internal principle circuit diagram of network analysis machine 163 of Drawing 13 is shown in Drawing 14. Network analysis machine 163 comprises microprocessor 171 connected to optical textiles network 24 via demodulator 175, and reception change circuit 176 and receiver 177 on the other hand by one side via abnormal-conditions machine 172, and transmission change circuit 173 and transmission machine 174. A horizontal conductor is between transmission change circuit 173 and reception change circuit 176, and this conductor side is connected to microprocessor 171. There is an optical textiles outgoing end of the same a large number as having connected the together joining point to transmission machine 174 in transmission machine 174. The outgoing end is equipped with the laser diode which emits green. Corresponding to this, there is an optical textiles input edge of the same a large number also in receiver 177 as the together joining point connected with the receiver. As a receiving element, the photo diode or optical transistor which operates only in the color field of an inspection signal here is equipped. In order to inspect network 24, it is controlled by microprocessor 171, and a predetermined laser diode is connected by transmission change circuit 173, and the amplitude modulation of fixed frequency and amplitude is added to the light of this diode by it. In this case, corresponding abnormal-conditions diode current is outputted with abnormal-conditions machine 172. This lightwave signal is connected to the laser diode (refer to the 13th figure). Simultaneously, the same receiving element is connected to demodulator 175 by reception change circuit 176. The above-mentioned receiving element belongs to straight line light pipe 167 which should be inspected. In this case, this receiving element changes a lightwave signal into a corresponding electric signal. Inside demodulator 175, from an electric signal, an abnormal-conditions signal is returned and is supplied to the A/D conversion machine which is not illustrated. This converter outputs the digital signal equivalent to signal voltage to microprocessor 171. This processor compares with the desired value which memorized the voltage measured to branching (light pipe 167) relevant to network 24, and memorized this voltage value similarly to branching. Since an inspection signal and abnormal conditions have maintained the amplitude uniformly, only when inspection branching of network 24 has a defect, a difference arises in a desired value and an operation value. Microprocessor 171 controls all the change processes performed by transmission change circuit 173 and reception change circuit 176. In this case, this processor appoints each inspection circuit to all the branching of network 24 according to an internal program, and sends the data corresponding to each state of network 24 to one of the operation units of inspection unit 135. Since reliability is improved, the above-mentioned network analysis machine 163 is connectable with three-piece parallel. For this reason, the connecting end corresponding to position 178 must be connected to one operation unit 137,138,139 each of inspection unit 135, respectively. If a network analysis machine is formed as an internal configuration element of inspection unit 135, it is effective. In the arrangement described previously, the lightwave signal which communicates via light pipe networks 20 and 24 made into the shape of meshes of a net is not limited to the explained modulation method, and another modulation method rather like pulse frequency modulation (PFM) or pulse code modulation (PCM) according to condition of use is also possible for it. The surveillance and control of this invention by inspection unit 135 which carries out digital communication using measurement / change unit 115,131,124 are not limited to the illustrated energy supplying device, and, in the case of the airplane equipped with the device which transmits a control signal to a circumference unit, for example, can be extended. When a rudder breaks down especially, for example, in relation to each emergency, the special extraordinary program of the memory machine of inspection unit 135 can be used. The greatest meaning of this invention is at the equipment which requires reliability very high to a degree, and the point that this invention can be used for a system. The current supply equipment to control of a space flight object, the process control of a nuclear power plant, a hospital especially an operating room, or an intensive nursing room, etc. belong to this, for example.
