After the AGV reaches the position of the automatic feeding station, it needs to inform the information system to grab the charging box, put the empty charging box back on the AGV and feed back the completion information of the charging. The AGV can leave after receiving the information.The AGV request automatic feeding process is as follows:After the AGV arrives at the charging port (the request can only be sent out after it reaches the precise charging port), the AGV system requests the information system for the charging of the bin, and the information system interacts with the charging system. After the AGV sends the charging request, the information system immediately feeds back the charging OK information, which represents that the information system receives the request. The process logic of AGV and the feeding system is connected by photoelectric switch. After AGV reaches the feeding port, AGV photoelectric sends out the feeding request. After the feeding system takes the charging box off the AGV and completes the feeding and puts it back to AGV, the feeding system returns to the safe position. PLC system feeds back to the AGV system through photoelectric switch, and the AGV can leave.
