Abstract

The invention discloses a LoRa-technology-based partial discharge acquisition system and a communication method. The system comprises a data acquisition module, an aggregation node module and a background service module. The communication method of the system comprises the steps that the data acquisition module transmits data information of each node to the aggregation node module in a LoRa wireless mode in a time-phased polling mode; and the aggregation node transmits LoRa data to the background service module in a time-phased polling mode. According to the invention, a partial discharge sensor with LoRa node equipment, a LoRa gateway, a 4G communication mode and a data background are adopted to form the partial discharge acquisition system based on the LoRa technology and the communication method. Since the data transmission distance of the LoRa node device is long and the power consumption is low, the networking mode coverage rate of the sensor acquisition network is large; the stability of data transmission is improved through node combination and network optimization configuration, so that the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric equipment insulation state detection, and in particular relates to a partial discharge collection system and a communication method based on LoRa technology. Background technique [0002] Since the 1950s, my country's power public utilities have developed rapidly. By the end of the 20th century, the installed capacity of my country's power system had exceeded 140 million kilowatts, and its annual power generation was also among the top in the world. While the voltage level of my country's power system continues to rise, people pay more and more attention to the safe and stable operation of the power system. Serious power equipment failures will not only cause large-scale power outages, bring inconvenience to people's lives, but also bring great losses to the national economy. At present, there are manual inspections and wired inspections for power equipment inspections. Manual inspections requir...
