摘要
针对智能变电站关键设备温升监测的难题,提出了一种采用GSM(全球移动通信系统)与红外技术的温差比较法并应用在温升监控系统中,系统采用红外装置获取被测点温升,采用TA(电流互感器)自具电源为采集装置供电,RS485进行数据传输,GSM进行超温信息告警,试验结果证明所设计的系统能够有效对被测点进行温升实时监测。
For the difficulty of monitoring the temperature of the key equipment in intelligent substations,this paper proposes a tem-perature difference comparison method.It uses GSM and infrared technology application in temperature monitoring system.The system uses infrared device access pass by measuring point temperature rising and self-supplying power source for power supply.Using the method of RS485 for data transmission and GSM for overtemperature alarming information,the test result proves that the designed sys-tem can measure temperature real-time effectivly which monitors the measuring point.
