High-voltage cable online monitoring data acquisition device and method based on MQTT

The invention discloses a high-voltage cable online monitoring data acquisition device and method based on MQTT. The device comprises a data acquisition unit, an MQTT proxy server and a data processing unit. The data acquisition unit comprises a plurality of sensors, the sensors are connected with the MQTT proxy server through an MQTT protocol, and each sensor subscribes a specified topic to the MQTT proxy server; the data processing unit is connected with the MQTT proxy server; when monitoring data of each sensor changes, a JSON message is organized according to an agreed format to serve as a load of an MQTT protocol to be sent to a specified topic in the MQTT proxy server, the data processing unit receives data of the specified topic and then analyzes the data, and high-voltage cable online monitoring data collection based on the MQTT is completed. According to the invention, unified acquisition of different types of sensors and different types of monitoring data can be realized. 本发明公开了一种基于MQTT的高压电缆在线监测数据采集
