基于物联网的500kV地下变电站温湿度检测系统研究

Temperature and Humidity Detection System of 500kV Underground Substation Based on the Internet of Things

从500kV全地下变电站生产实际出发,结合端到端的物联网开发,从原理、方法、设计等多方面,对站内温湿度实时在线监测进行了设计研究。根据站内建筑结构、设备分布、电缆走向等特点,使用STM32主板搭载温湿度传感器和WIFI模块进行数据采集,通过MQTT协议连接共有云物联网平台,再将数据通过HTTP协议传输到站内服务器和用户Web端页面,完成在线监测功能。

Based on the production practice of 500kV all-underground substation and the end-to-end development of Internet of Things,the design research of real-time on-line monitoring of temperature and humidity in the station are carried out from various aspects such as principle,method and design.According to the building structure,equipment distribution,cable trend and other characteristics of the station,the STM32mainboard is equipped with temperature and humidity sensor and WIFI module for data collection.The common cloud Internet of Things platform is connected through MQTT protocol,and the data is then transmitted to the server and the user′s Web page through HTTP protocol,completing the online monitoring function.
