基于云服务的干式变压器远程监控终端设计
|
摘要
针对干式变压器出现的故障问题,研制出了一种基于云服务的远程监控终端,该终端通过数据采集模块对温度、电参量等参数进行实时采集与显示,并根据温度自动控制风机启停、声光报警、保护跳闸,还可以通过GPRS无线通信与GPS全球定位相结合的模块定位变压器,并将采样数据发送到指定手机号进行状态监控;另外终端可以通过云服务器实现远程数据的接收、存储、发送等功能,并能通过云服务器向上位机传输位置与采样参数信息,方便对每一台变压器同时实施远程监控。
Aiming at the failure of dry-type transformers,a remote monitoring terminal based on cloud services was devel-oped in this paper. The terminal collects and displays parameters such as temperature and electrical parameters in realtime through the data acquisition module,and automatically controls the start and stop of the fan according to the tempera-ture. Sound and light alarm,protection tripping,GPRS wireless communication and GPS global positioning module posi-tioning transformer,and send the sampled data to the specified mobile phone number for status monitoring; In addition,the terminal can achieve remote data reception,storage,sending and other functions through the cloud server,as well astransfer position and sampling parameter information to the upper computer through the cloud server,so as to facilitate theimplementation of remote monitoring of each transformer at the same time.
