Controller

[Detailed Description of the Invention]

This invention relates to control device 1 using processing units, such as a microprocessor which always operate by an exchange power supply and operates with a battery etc. at the time of 1 power failure, especially the power consumption reduction-ized book type at the time of the power failure in that control device. It is Tremor rare To that there is little power consumption at relations, such as 1 compensation time and battery Rice, to the time of 1 power-failure compensation as much as possible in the device which generally performs power failure compensation with a battery etc. Block diagram 1 figure 2 showing the conventional example of the control device with which Drawing 1 used the microprocessor is a flow chart for explaining the operation. In the 1st wI, l is a clock generation machine and 2 is microphone 4 A p Sessa, As for a WA I T circuit (standby) and 4, in 3, an input/output device (Ilo) and s are power failure detector circuits, 6 is Electricity j11 circuit, and as for 7, a battery and 8 are (■) when microphone lob rice field Sessa 2 is started by in Tarabud (interruption) signal IN emitted for every constant period from O clock generation circuit 1 which is a change circuit, As for my Crypt rice field Sessa 2, Acceptance performs predetermined processing based on a program predetermined in (■) 0 microphone p A p Seta 2 which repeals interruption after attaching this in Tarabud signal IN ((Ri)). When a WAIT command is executed, they are (■), data bus DB, and address bus AB, While zero microprocessor 2 by which WA I T order signal WTI is sent to WA I T@ way 3 via l10(input/output device)4 will be in a WAIT state with WA I T signal WT from the circuit 3 If it investigates whether a receptionist changes primary in Tarabud signal IN into a possible state, and there is any (0) 1 interrupt request and there are ro and an interrupt request, it will return to ■ and the same operation as the above will be repeated, and it stands by until there is the next demand, if there is nothing. With - which can be power-consumption-expense-reduced by there being little power consumption in case micro Presenter 2 is in a WA I T state compared with other operating states, therefore carrying out like the above, and time, microphone 4 which performs such processing operation -- at the time of usual, if a power failure is detected in 1 power-failure detector circuit 5 although it is operating with the electric power from exchange snowy field circuit 6, A a Set ?2 will change Electricity j16 to battery 7 A charter by change circuit 8, and they will supply electric power from the battery 7. For this reason, by 0, however 1 this gentleman type which can act as Takayuki of the Pregram at the time of a power failure as well as the above, and can perform 1 predetermined processing, Mike shive rho Sena 2 is the same, therefore in order to lengthen power failure compensation time, the time of energization and power consumption's of power failure-1 needs to increase battery capacity. However, increasing 1 capacity has a layer, while saying that a space becomes large and 1 and a charge circuit become complicated. Therefore, the object of this invention is to reduce further the power consumption at the time of the power failure of the control device having processing units, such as a microprocessor. In the 1 present invention, the above-mentioned object operates with a constant periodic interruption signal, lengthens an interruption time period at the time of a power failure of a control device having a processing unit which it comes to drive by battery compensation at the time of a power failure, and lengthens standby time of a processing unit, that is, lengthens low-power-consumption time. Therefore, it is attained. the [ hereinafter, / which are a block diagram in which <>ssm which describes the example of this invention with reference to drawings shows the example of this invention, and a flow chart Drawing 4 explains operation of Drawing 3 to be / Q / S ] -- the same amount of A mark is attached and shown about the same thing as 132 figure. clear also from these figures -- as -- a sake -- this invention -- the 1.! the conventional system explained by [-- the time of a power failure -- Ri W Poke CL, While adding Vengeance change circuit 9, the judgement function (see flow chart ■ of Drawing 4) of being the Meeting power failure which enabled it to detect 1 power-failure Detection tDll by microphone stomach Powered by Translate 7 Thu+2 via l10(input/output device)4 is given. That is, since Experiment detection signal DB beam p Poke change circuit 9 will be given if one power failure is detected by power failure detection-way 5 although the same operation as Above is performed at the time of Tortoise wedding (usual), clock change circuit 9 changes a clock generation circuit 1 paste p ivy to CL from CL. if the cycle of critter CL, is lengthened rather than the cycle of Rice field ivy CL, here at the time of a power failure at the time of 1 energization -- 1 -- the WAIT state of a microprocessor becomes long so much, therefore power consumption can be reduced. Pass I 10@ Place 4 for this power failure detection signal DI! If it is made for processing time to change to short paddle power failure processing (see sigma which is the 3rd mW) rather than processing in one microprocessor 2 at the time of energization by giving Microphone p Palm gesture Seth f2, power consumption can be reduced further. Since it is the same as that of explanation of Drawings 1 or 2 about other points, it omits. above -- 1 -- since low-power-consumption-ization much more than 1 can be attained in the control device to which operate a microprocessor and made it make predetermined processing perform by battery compensation at the time of a power failure according to this invention, When carrying out power failure compensation of the same time as the former, the battery capacity can be lessened. If it puts in another way and 1 battery capacity is the same, power failure compensation time can be made longer than before. 1 -- this invention is applicable to the general device which needs to operate a place ii device at the time of the same composition as the above, i.e., a power failure.
