摘要
针对传统箱式变压器环境监测系统线路复杂和实时性差等问题,提出一种基于TCP协议的自适应无线网络箱式变压器数据监测系统。该系统利用RS 485总线通过ModBus协议采集箱式变压器内部多点温度、湿度、油温的环境参数和三相电压电流、电能、功率因数、频率等电力参数。MCU接收到数据后进行分析处理,将监测参数实时显示在人机交互界面上,可以对突发情况进行预警及控制。同时这些数据通过可选择的三种方式GPRS,WiFi或者以太网口发送至云端服务器,用户可登录服务器上位机,远程监测箱式变压器内部状态。经过试验测试,该系统可以正常监测箱式变压器内部参数,极大地方便了工作人员的维护和检修工作,提高了箱式变压器的使用寿命。
As the traditional box-type transformer environmental monitoring system has complex circuit and poor real-time performance,an adaptive wireless network box-type transformer data monitoring system based on TCP protocol is proposed. The system uses the 485 bus to collect the environmental parameters of the multi-point temperature,humidity and oil temperature and the three-phase voltage,current,electric energy,power factor,frequency and other power parameters of the box-type transformer by means of the MODBUS protocol. After receiving the data,MCU can analyze and process it,display the monitoring parameters on the human-computer interface in real time,and can give early warning and control to emergencies. The data is sent to the cloud server by means of three selectable modes of GPRS,WIFI or Ethernet port. Users can log in to the server of the upper computer and remote monitor the internal state of the box-type transformer. The testing experiment results show that the system can normally monitor the internal parameters of the box-type transformer,which greatly facilitates the maintenance and overhaul of the staff and improves the service life of the box-type transformer.
