Ⅰ类热像仪故障诊断

Fault Diagnose of Class I Thermal Imager

开发一种用于检测热像仪电路故障并显示的专用测试设备是很有必要的。今提出了诊断热像故障的一种方法 ,即测试整机电路的特征信号 ,根据测量结果自动判断故障。由于热像仪电路的模块化设计 ,所有故障均应定位在这些模块上。

It is important to develop a equipment for the test of thermal imager circuit and displaying the fault. A fault diagnose method of thermal imager by means of testing characteristic signal of circuit is suggested. According to the result of test, the sort of fault can be determined. Owing to the moduliarity design of thermal imager circuit, the faults should be positioned on these modules.In fact, pratical repair of thermal imager becomes a process of module substitution.
