新型配电柜WIFI无线温湿度传感系统研究

Research on the New WIFI Wireless Temperature/Humidity Sensing System for Distribution Cabinets

摘要: 随着物联网技术的发展，温湿度监测已经广泛应用在日常生活、工业、医学、环境保护、化工、石油等领域。由于配电柜的湿度波动范围宽、实现精确测量难度大，同时安装成本受限，现有的温湿度监测产品很难满足电力系统用户的多样化需求。因此，本系统采用STM32F103C8T6芯片作为主控，通过DHT11模块来收集所处环境的温湿度数据，并利用ESP8266模块将监测到的数据上传到中国移动的OneNET云平台，使用OneNET云平台创建自有的产品和设备，利用数据可视化实时展示收集来的数据。系统的硬件部分采用模块进行搭建，使整个系统安装简单且更加便于维护。根据系统制作了实物，并进行了相关的测试实验，结果表明系统完全满足电力配电柜应用需求。

Due to the wide range of humidity fluctuations in distribution cabinets, the difficulty of achieving accurate measurement, and limited installation costs, existing temperature and humidity monitoring products are difficult to meet the diverse needs of power system users. Therefore, this system uses the STM32F103C8T6 chip as the main controller, collects temperature and humidity data of the environment through the DHT11 module, and uploads the monitored data to China Mobile’s OneNET cloud platform using the ESP8266 module. The OneNET cloud platform is used to create its own products and devices, and the collected data is displayed in real-time through data visualization. The hardware part of the system is built using modules, making the installation of the entire system simple and easier to maintain. Based on the system, physical objects were made and relevant testing experiments were conducted, and the results showed that the system fully meets the application requirements of power distribution cabinets.
