多类变压器智能监测系统的设计与实现

Design and realization of intelligent monitoring system for transformer

针对目前变压器监测系统的电流测量不精确、无法对多种类变压器进行系统分类、数字化智能监测等问题,设计并实现一套智能监测系统。该系统由数据采集终端、网络服务器、客户端三部分组成。数据采集终端采用Cortex-M4为核心的ARM处理器,利用罗氏线圈等传感器采集变压器状态信息,并通过GSM网络远程发送到服务端。服务端搭建以微软.Net的B/S架构,用于分类管理和记录接收数据信息等。智能手机、PC端通过GPRS实时更新数据,用于观测数据、修改状态参数报警阈值等。经某电力公司测试,该系统运行稳定,具有系统分类明确、监测数据准确、使用便捷的特点。

Aiming at the problems of current measurement in transformer monitoring system,such as inaccuracy,inability to systematize and digitize many kinds of transformers,an intelligent monitoring system is designed and realized. The system is composed of data acquisition terminal,network server and client. The data acquisition terminal adopts the ARM processor with Cortex-M4 as the core,uses sensors such as Roche coil to collect the transformer state information,and sends it to the server remotely through GSM network. The server is built with Microsoft.Net's B/S architecture for classification management and recording of received data information. Smart phones and PCs update data in real time through GPRS to observe data and modify alarm threshold of status parameters. Tested by a power company,the system runs stably,with clear system classification,accurate monitoring data,and convenient use.
