| 摘要: |
| 为保证变电站中露天安置设备的安全运行,提出了现场环境设备温度监控的设计方案.该方案基于无源无线温度传感器,安装在现场的测温传感器的温度量转化为红外信号并发射,接收端的红外监控摄像机对传感器扫描接收,PC机对提取的红外图像处理、分析后,给出温度指示和异常报警信号.测温传感器采用温差模块直接向红外管供电方式;采用热敏电阻网络进行温度补偿;利用高斯-牛顿和麦夸脱算法对热敏电阻网络的参数进行优化计算.通过实际检验,所设计的方案获得满意的效果. |

| Abstract: |
| A temperature monitoring scheme is designed for the open site devices of substation to ensure its safe operation,which is based on the passive wireless temperature sensors.The site sensors convert the temperature measurements into infrared(or visible) light signal and transmit,the infrared camera scans sensors and receives the signals,and the monitoring system displays the temperature and issues alarm for abnormality after processing and analyzing the signals.The temperature sensor uses temperature differen... |
