Design of a sensor terminal serial communication module for power transmission and distribution equipment based on data protocol of sensors in Internet of Things

Abstract

The State Grid actively promotes the development of a new power system. The internet of things for power transmission and transformation equipment, for example, is a significant way to open up the "last mile" of power grid communication. In this paper, we design a sensor terminal serial communication module to meet the internet of things business requirements for power transmission and transformation equipment while also realizing sensor data collection and reporting functionality. The results of the tests show that the serial communication module designed in this paper can help the sensing terminal and reliably report sensing data to the upper-layer access node.
