Control system and method for CAN (Controller Area Network) equipment with same ID (Identity) based on switch matrix

The invention discloses a same-ID CAN device control system and method based on a switch matrix, and belongs to the technical field of the Internet of Things, and the system comprises an MCU control module, an input interface unit, a switch matrix, an output interface unit, a switch control unit, and a plurality of CAN transceivers. A signal transmission path is controlled through the switch matrix, so that a plurality of devices with the same CAN ID can be connected and controlled on a single CAN bus, and a CAN bus instruction is accurately transmitted to a specified CAN transceiver; besides, a signal transmission path is controlled through the switch matrix, so that the accuracy, reliability and rapidity of CAN equipment switching can be ensured, and flexible and reliable switching of CAN equipment with the same ID is realized. 一种基于开关矩阵的同ID CAN设备控制系统及方法，属于物联网技术领域，包括：MCU控制模块、输入接口单元、开关矩阵、输出接口单元、开关控制单元和若干数量的CAN收发器；通过开关矩阵控制信号传输路径，能够满足单路CAN总线上连接并控制多个具有相同CAN ID的设备，准确地将CAN总线指令传输至指定CAN收发器；此外，通过开关矩阵控制信号传输路径，能够保证CAN设
