非接触式电站高温预警系统设计

Design of non-contact fire monitoring and pre-warning system for substation

摘要:

配电站中的故障电气设备的工作温度会处于高于其正常工作温度的状态,易造成火灾。设计了一种非接触式的实时高温预警系统。系统利用长波红外相机对被测试目标进行非接触式灰度成像,基于LabVIEW上位机实时采集图像并对图像数据进行处理,从而得到所拍摄电气设备实时工作温度。若此温度值高于电气设备安全工作的最高温度值,下位机报警,工作人员可根据系统所成图像确定故障位置,进而提前排除安全隐患。测试结果表明：系统运行稳定、操作简便。系统能够有效地对电站中的电气设备运行状态进行实时监测和精确预警,极大程度地降低了工作人员的安全风险,提高了工作效率。

Abstract:

The working temperature of the faulty electrical equipment in the substation will be higher than its normal working temperature, and it is easy to cause fire. This paper designs a non-contact real-time fire early warning system. The system uses a long-wave infrared camera to perform non-contact grayscale imaging on the target. The host computer uses the LabVIEW software to collect images in real time and processes the image data to obtain the real-time working temperature of the electrical equipment in the substation. If this temperature value is higher than the maximum temperature for the safe operation of electrical equipment, the slave computer will alarm, and the staff can determine the fault location based on the image made by the system, and then eliminate the potential safety hazards in advance. The test results show that the system has a stable operation and an easy operation. The system can effectively monitor and accurately predict the operating status of electrical equipment in the substation, which greatly reduces the safety risks of workers and improves work efficiency.
