摘要：
The development of digital twin technology of electrical equipment promotes the application of various new sensing technologies in the power industry, and a stable and clear data cloud channel is urgently needed to provide electrical equipment twins with more in-depth status analysis and fault prediction. For this reason, we developed a dual antenna radio frequency identification(RFID) acceleration and temperature sensor with metal reflector. Then, we designed the data package format in the RFID sensor system and the transmission channel, and uploaded sensor data to the Internet of Things cloud platform via the message queuing telemetry transport (MQTT) protocol over a 4G network by way of an edge gateway. Finally, the OFPSZ-150000/220 transformer was taken as an example for sensor testing and data transfer protocol application. The results show that the designed data transmission protocol mainly exists in the RFID sensor channel, with a packet loss rate of 11.3% within 2 meters and 38.2% at the farthest communication distance of 3 meters. There is hardly any problem of packet loss in the channel where data pass through the cloud on the edge gateway. The research shows that the designed RFID sensor is practical and the data communication protocol channel is stable and reliable. © 2022, High Voltage Engineering Editorial Department of CEPRI.
