Abstract: In view of the serious fragmentation of the substation sensing terminal and the insufficient application of the Internet of Things technology, based on LoRa low power consumption wireless communication technology, a scalable, low power consumption, wireless intelligent sensing node is designed and developed using wireless communication modules and micro control units. The sensing node can collect and transmit the data of the substation environmental state sensing parameters. The test results show that the data transmission of the sensing node is stable, the communication packet loss rate is 0 within 1 500 m, the power consumption of the sensing node is about 4.62 mAh/D, and the effective working time can reach 5 years. The design of the node can provide some reference for intelligent monitoring of substation environmental status.
