The invention discloses a communication method, system and device of a battery changing cabinet and a storage medium, and the communication method comprises the steps that a slave cabinet receives an instruction message sent by a master cabinet through a CAN filter, wherein the instruction message carries target slave cabinet sending identification information; and if the identification information sent by the target slave cabinet is the same as the identification information received by the slave cabinet of the CAN filter, the CAN filter sends the instruction message to a processing unit of the slave cabinet. It can be seen that the slave cabinet receives the instruction message sent by the master cabinet through the CAN filter and extracts the target slave cabinet sending identification information carried in the instruction message, and when the target slave cabinet sending identification information is the same as the slave cabinet receiving identification information of the CAN filter, the CAN filter sends the instruction message to the processing unit of the slave cabinet. Therefore, it is guaranteed that only the target slave cabinet receives the correct instruction message, and the situation that after other slave cabinets receive the message, data are disordered and run dead is caused is avoided.
本发明公开一种换电柜的通信方法、系统、设备以及存储介质,通信方法包括:从柜通过CAN筛选器接收主柜发送的指令报文,所述指令报文携带目标从柜发送标识信息;若所述目标从柜发送标识信息与所述CAN筛选器的从柜接收标识信息相同,所述CAN筛选器发送所述指令报文至所述从柜的处理单元。可见,本发明从柜通过CAN筛选器接收主柜发送的指令报文,提取指令报文中携带目标从柜发送标识信息,当所述目标从柜发送标识信息与所述CAN筛选器的从柜接收标识信息相同时,所述CAN筛选器发送所述指令报文至所述从柜的处理单元,从而保证仅目标从柜接收正确的指令报文,避免其他从柜收到报文后导致混乱数据而跑死。
