Pneumatic electromagnetic valve control method and circuit generally suitable for robot system

The invention provides a pneumatic electromagnetic valve control method and circuit universally suitable for a robot system. The method obtains a reference voltage and a time sequence control signal of the battery. And the processing drive circuit compiles, allocates register addresses and updates storage contents based on the input control signal, so as to realize the output of switch state control quantities Ai (i = 0, 1, 2) and Pi (i = 0, 1, 2, 3, 4, 5, 6, 7). And finally, the pneumatic electromagnetic valve branches can be debugged one by one by observing the on-off condition of the indicating lamp of the address indicating circuit, so that the troubleshooting manpower and time cost is reduced. The circuit design is efficient and simple, a power type load can be carried, the cascade switch circuit effectively inhibits surge current, and the potential safety hazards of power-on rushing and mistaken touch of the electromagnetic valve are eliminated; a large current loop and a small current loop are separate
