Design of temperature monitoring system for high-voltage
equipment based on wireless communication
Abstract：Based on the analysis of current temperature monitoring technologies for high-voltage equipment，this
article develops a system on the basis of wireless communications. In this system，the MCU on the high potential
side communicates interactively with the low potential side by means of the wireless transceiver modules on both
sides，so that the temperature signal of the high-voltage equipment can be sent to the low potential side. This
article focuses on the following key techniques ： the design of the antenna made of PCB in wireless
communications ； the power source based on solar cells in the high-voltage equipment ， for which energy is
provided by the MCU-controlled spotlight on the low potential side ， which steadily produces a 3.3 V voltage
through the low power voltage control module ； and the parameters and the processing method of a
well-performed temperature sensor. The tests in laboratory indicate the reliabilityof this system in communication.
