Document Type and Number:
WIPO Patent Application WO/2022/267245
Kind Code:
A1
Abstract:
Disclosed is a processing method for electromagnetic induction prevention of main and standby simultaneous driving relays of a safety driving unit. The processing method comprises: S102, periodically obtaining and detecting a driving command, S103, when the driving command changes, detecting a port state of an output port of a safety driving unit, S104, executing a corresponding processing operation according to the port state of the output port, and repeating the steps S102-S104. The processing method has the advantages that the next step of processing operation is performed according to the port state, the safety driving unit can drive the outside only after the port state is not abnormal, the method is guided to a safety side after the port state is detected to be abnormal, and the driving safety is further guaranteed.
