物联网在智能变电站辅助系统监控中的应用

为了提高智能变电站相关辅助系统的联动性，设计了一种集成到虚拟现实环境中的智能变电站辅助系统物联网原型。利用应用功能和任务均衡分配调度的边缘计算算法，实现了对单个边缘节点的有效控制，提高物联网智能变电站辅助系统的即时性和安全性。通过MQTT协议和Co AP协议传输数据，结合ESP-8266 Wi-Fi模块提高了信息交换速度并降低带宽消耗。利用ACS712电流传感器和HC-SR501运动传感器检测变电站各装置的实时状态，通过虚拟现实技术将监控管理信息展现给用户，实现了变电站内设备的完整监控功能。

Application of internet of things in intelligent substation auxiliary system monitoring

In order to improve the linkage of relevant auxiliary systems of intelligent substation，an intelligent substation auxiliary system Internet of Things prototype integrated into virtual reality environment was designed in this paper.Using the edge computing algorithm of application function and task balanced allocation scheduling，the effective control of a single edge node was realized，and the immediacy and security of Internet of Things intelligent substation auxiliary system were improved.The data was transmitted through MQTT protocol and COAP protocol，combined with ESP-8266 Wi-Fi module，which improves the information exchange speed and reduces the bandwidth consumption.ACS712 current sensor and HC-SR501 motion sensor were used to detect the real-time state of each device in the substation.The monitoring and management information was displayed to users through virtual reality technology，and the complete monitoring function of equipment in the substation was realized.
