Smart meters were developed with the maturity of microcontroller technology in the early 80s, and the world meter market was basically monopolised by smart meters, which was attributed to the need for enterprise informatization, and one of the necessary conditions for enterprises in the selection of meters was to have a networked communication interface. Initially it was the data analogue signal output simple process quantity, later the instrument interface was RS232 interface, this interface can realize the point to point communication way, but this way can not realize the networking function, then appeared the RS485 solved this problem.
