In this case, the method of setting up artificially a setup of the key in a transmitting station and a receiving station only among the persons concerned as most positive means that is not known by the third party is used. However, the situation which cannot communicate is generating To shake, if this is not correctly told when changing a setting key for the time of initial setting, or a certain reason. Especially generating of the situation where such contact cannot be taken in the information transmission method whose number of a transmitting station and receiving stations is a large number poses a very big problem on information transmission method management. [Problem(s) to be Solved by the Invention] The present invention is temporary Heartfelt (it is Offer (it aims at Jk 1-To.) about the information transmission method which you can be made to recover), when a key is in agreement, it makes between transceiver offices and communication becomes impossible again at Because. Since a key is not in agreement between transceiver offices, when communication becomes impossible, the invention of the second of the present invention is limited to the receiving station specified by a transmitting station, and an object of an invention is to provide the information transmission method which can recover communication temporarily. [Means for Solving the Problem] The first invention is provided with a common table in which a plurality of keys were recorded on a transmitting station and a receiving station, A means to be provided with a means to carry out the conversion process of the input signal to a transmitting station, and to transmit to it using one key in the table, to carry out inverse transform processing of the received signal in a receiving station using one key in the table, and to send out a reception output, In an information transmission method provided with a means to choose a key in the above-mentioned table which a transmitting station uses, it is in transmitting station ', It is a Send word about a position in the above-mentioned table about a key used now when specified by operation (Hand stem inserted in numerals). Numerals power which is provided with a means to insert in a transmitted signal numerals which identify that transmitted signal G This insertion carried out the position, and carries out account discernment of" 2 in a receiving station (inside (it had a means which detects information on Standstill and it gives to the above-mentioned means which chooses) of a received signal to a table when received) The second invention is provided with a common table in which a plurality of keys were recorded on a transmitting station and a receiving station, and is transmitting station G This, A means to be provided with a means to carry out the conversion process of the °zeta input signal, and to transmit using one key in the table, to carry out inverse transform processing of the received signal in a receiving station using one key in the table, and to send out a reception output, In an information transmission method provided with a means to choose a key in the above-mentioned table which a transmitting station uses, it is in a transmitting station, A means to insert in a position i transmitted signal in an account table of" 2 about 4-1 used now when specified by operation, It has a means to transmit a number which specifies a means to insert in a transmitted signal numerals which identify having inserted the position in a transmitted signal, and a receiving station, and is in a receiving station, A means to detect that a number which specifies a received receiving station is a number of a self-office, and this means had a detection output, and when the above-mentioned talent name of an era which identifies was received, information on a position in Tape * Le was detected from a received signal, and it had the above-mentioned means G This gives means which chooses. [For Work ] When a key is not in agreement between transceiver offices according to a certain cause and communication becomes impossible, from a transmitting station, A" Addition of the key information is carried out, and an invention of the first of the present invention transmits it, receives using key information received from this transmitting station, and recovers communication temporarily in a receiving station. Since key information is transmitted, when monitored by third party, communication will be revealed, but when communication becomes impossible, it uses temporarily, and there is an advantage which does not continue a communication impossible state. The second invention performs above temporary recovery only about a receiving station specified by a transmitting station, when a large number [ a receiving station ]. [Example] Drawings are referred to for the example of the present invention, and it is explanation 1-To. Drawings 1 are the Off * mouth and a Poke lineblock diagram of present invention one example information transmission equipment. Digita J This example is an example of the method which is held, and is changed and transmitted to a signal about voice information. An analog audio signal is connected to analog digital converter 2 from microphone 1 of a transmitting station. A digital audio signal is connected to scrambler 3 from analog digital converter 2. It is connected to scrambler 3 provided with the table as the receiving station where the key which is plurality was recorded with same key information set up by manual operation from key set part 4. The place by which it is characterized [ of the present invention ] here is a key information transmitting portion enclosed with - and six broken chain lines. That is, the digital audio signal by which the conversion process was carried out to the random pattern according to key information from scrambler 3 is connected to key information synchronizer 5. When a special key is specified by operation, key information is connected to key information reading part 6 from key specification part 4, and the key information in which the key information insertion identification signal was inserted from key information reading part 6 is connected to key information synchronizer 5. It is connected to transmission I19 and the output signal with which the above-mentioned key information was compounded from key information synchronizer 5 is transmitted from transmitter 9. Next, the transmitted signal is received by receiver 11 of a receiving station, and the output signal of receiver 11 is connected to separation part 12. The signal with which only digital voice-information was separated from separation part 12 is connected to descrambler 13. The place by which it is characterized [ of the present invention ] here is a key information extraction portion enclosed with a dashed dotted line. The output signal of a sand straw and receiving l1ti is connected to key receiving primary detecting element 14. The key information detection signal from key receiving primary detecting element 14 is connected to the control input of switch part 19. Receiver]

The output signal of l is connected to key 11 II oil extraction 20. The key information extracted from key information extraction part 20 is connected to input A of switch part 19. ; The key information from the Thau set part 21 is connected to human power B of the above-mentioned switch part 19. Input B of switch part 14 is switched to ' case with the detection signal from key receiving primary detecting element 14 by input A. Output C of switch part 19 is connected to descrambler 13 provided with the table in which a plurality of same keys as a transmitting station were recorded. From descrambler 13, inverse transform processing was carried out, it becomes random, and a nothing digital audio signal is connected to digital analog converter 22. An analog audio signal is connected to speaker 23 from digital analog converter 22, and a sound is outputted from speaker 23. Operation of the information transmission equipment of such composition is explained. In a transmitting station, from microphone 1, an analog audio signal is inputted and it changes into a digital audio signal with analog digital converter 2. Although a conversion process is carried out to a random pattern by scrambler 3 after this, according to the key information set up by manual operation in key set part 4 at this time, scrambler 3 performs a conversion process. Human power of the output of scrambler 3 is carried out to Even more information synchronizer 5. Here, if the preset value in key set part 4 is 1 special number, although key information synchronizer 5 performs key information composition for the result of having read key information by key information reading part 6, further, composition of key Sentiment 1 will not be performed about other 1 general numbers. The output signal of key information synchronizer 5 is transmitted from transmitter 9. In a receiving station, only a digital audio signal separates the result received by reception 4111 by separation part 12, and also it returns to the signal which is not made random by carrying out inverse transform by descrambler 13. Here, if key information is included in the output signal of receiver 11, key receiving primary detecting element 14 will answer, and it will connect switch part ■9 to input A shown in Drawing 1. Since the key information received from key information extraction part 20 is outputted to input A, according to the key information on key information extraction part 20, inverse transform processing of descrambler ■3 is carried out at this time. If key information is not included in the output signal of receiver 11, key receiving primary detecting element 14 will not answer, but the key information on input B will be outputted to output C of switch part 19. input B -- The -- oh, since it caulks and 1 Thau information is set to key set part 21 by manual operation, at this time, A desk rambler 13 performs inverse transform to a setup of key set part 21. Human power of A desk rambler's 13 output is carried out to digital analog converter 22, it is changed into an analog audio signal, and is outputted as a sound with speaker 23. Operation of getting down to Drawing 1 is performed as follows. Usually, by the promise only between the persons concerned, it is used between a transmitting station and a receiving station, respectively, setting to key set part 4 and a 21 Inspector-key. Therefore, the key information used at this time is not told outside, and transmission of information is performed. However, there are change by the convenience on a setting mistake or maintenance, etc., and when a difference arises between key set part 4 and key set part 21 and the situation which cannot communicate occurs, it is operated as follows temporarily. A key preset value is chosen as the special key defined beforehand in a transmitting station. At this time, key information is transmitted to a transmission way from key information reading part 6 and key information synchronizer 5. In a receiving station, if key receiving primary detecting element 14 detects this key information, switch part 19 will be switched to human power A, the key information which key receiving primary detecting element 14 received from the transmission way will be given to descrambler 13, and descrambler 13 will operate according to the output of this key receiving primary detecting element 14. As a result, since conversion and inverse transform will be inevitably performed corresponding to the same key, in a receiving station, the desk ramble of a transmitting station and the receiving station is certainly carried out normally, and voice information is acquired. Since key information is transmitted about the above "special key", a possibility of being known by the third party comes out of this, but it limits to emergency intelligence, and if frequency in use is very low, the opportunity will hardly become a problem. There is an advantage on which the situation which cannot communicate at all to it is avoided, and urgent connection is possible at the time of necessity. Drawing 2 is a block lineblock diagram of other example information transmission equipment of the present invention. In Drawing 2, the same numerals show the same portion as Drawing 1. as opposed to the composition shown in Drawing 1 in Drawing 2 -- an identification number (t JJLI and transmitting -- a receiving station -- 1. -- only the office which suits this number can take correspondence of descrambler 13, and can be made to do voice communication normally.) That is, in a transmitting station, identification number synchronizer 7 for compounding the preset value by ' identification number set part 8 to the output of key information synchronizer 5 is provided, and it transmits from transmitter 9G This. To everything but key receiving primary detecting element 14 which detects reception of key information in a receiving station, and key information extraction part 20 which extracts key information, Identification number set part 17 for the standard of identification number extraction part 15, judgment part 16, and judgment part 16 is provided, The identification number obtained by identification number extraction part 20 and the value of identification number set part 17 are inputted into judgment part 16, only when in agreement, and gate 18 "is turned on" on, and a hammer performs switching control of switch part 19 to the response of key receiving primary detecting element 14. In the example of a Sad straw and Drawing 2, only when the identification number of identification number set part 17 and identification number extraction part 15 is in agreement between a transmitting station and a receiving station also at the time of emergency intelligence transmission, inverse transform is normally performed by descrambler 13, voice 10 news is obtained, and information transmission becomes possible. If it does in this way, while many receiving stations exist, for example, it will become possible to take urgent contact only to the specific receiving station which it is. [Effect of the Invention] In the present invention, as explained above, a key information reading part and a key information synchronizer are provided in a transmitting station, and a key receiving primary detecting element, a key information extraction part, and a switch part are provided in Establishment and a receiving station. Therefore, where digital information is made random by a transmission on the street to the usual use, it transmits, Also when it can transmit so that a partner office may be known, and a key setup has a difference between a transmitting station and a receiving station, there is an outstanding effect which can perform transfer of emergency intelligence by choosing a special key in a transmitting station. furthermore -- providing an identification number set part and an identification number synchronizer in a transmitting station -- a receiving part -- an identification number set part, an identification number extraction part, a judgment part, and an and gate -- To set up -- there is an effect that urgent contact can be taken only in the specific receiving station in many receiving stations, by things.
