AGV peripheral control method based on PLC

The invention relates to an AGV peripheral control method based on a PLC, and the method comprises the steps that system construction: the PLC is arranged on an AGV body, the AGV body is connected with a scheduling system, an upper computer system and a peripheral mechanism, a vehicle-mounted controller is arranged in the AGV body, the upper computer system, the scheduling system and the vehicle-mounted controller are sequentially in communication connection, and the PLC is in communication connection with the vehicle-mounted controller and the peripheral mechanism; and AGV peripheral control: the vehicle-mounted controller receives the task number transmitted from the upper computer system in real time and forwards the task number to the PLC, and the PLC calls a corresponding pre-stored peripheral mechanism control program according to the task number to control the peripheral mechanism to act. Compared with the prior art, the invention provides a peripheral control mode with high stability and portability,
