Method for realizing multi-device time-sharing communication based on electric meter

The invention provides a method for realizing multi-device time-sharing communication based on an electric meter, a plurality of devices are hung under the electric meter, and a communication unit of each device adopts a BPL carrier module, a 485 communication module, a PLC carrier communication module, a GPRS communication module or an RF communication module; an external infrared communication device sends a communication module serial port request frame to a communication object through the electric meter; after receiving a pulse signal, the communication object performs task arrangement according to the current process, and if the communication object is currently busy, the communication object continues to execute the current task until the communication object is idle; and after the communication object processes the data received from the electric meter end, the idle state is ended, and other tasks are executed. According to the multi-device time-sharing communication of the electric energy meter, the
