Abstract: PURPOSE:To detect abnormal supply of a clock to a microcomputer securely and to deal with it speedily, by detecting whether a clock signal is being generated or not at a clock signal output terminal, deciding on the occurrence of a fault when no lock is generated, and generating an alarm. CONSTITUTION:The oscillating circuit consisting of a crystal oscillator 2 and capacitors 3 and 4 is connected between terminals X1 and X2 of the microcomputer 1 and used as a system clock oscillating circuit to output clock pulses CP from the clock output terminal CL. Those pulses are detected by a clock pulse detecting circuit 5; when the pulses CP are outputted, a minus voltage is applied to the base of a transistor TR16 for driving a warning lamp 15 and when no pulse CP is outputted, a plus voltage is applied to the base of the TR16 to generate an alarm. The detection signal of the circuit 5 is applied to the base of a TR23 for generating a fail-safe signal FS and this TR generates the signal FS when the pulses CP are ceased to secure safety.

And when the square wave is applied to the gate of the FET via pulse transformers 511-514, the PP action is secured to deliver the output to primary windings 331- 33n of the transformer. These outputs are then connected to one unit of a primary winding 33S and then delivered 41 via tuning circuit 40. The current to be supplied to the blocks is detected 381-38n to detect the fault. And when the load increment of the normal blocks reaches the limit, the output is reduced in accordance with the unit number of normal blocks. The amount of reduction is controlled by circuit 39 including the logic circuit. In such way, the serial breakdown can be prevented for the normal blocks.

The evaluating function J is expressed by the expression in the Figure. The function J is sequentially corrected in correspondence with the fluctuation of the system such as acceleration and deceleration by the algorithm of the conjugate grade method. Thus implementation of the speed response and stablization of the control system can be realized.
