In the embodiment of the present invention, the thermal imaging photographing unit 110 is arranged to monitor the temperature condition of the circuit environment, and once the temperature in the environment is abnormal, an alarm needs to be given in time to avoid circuit failure and even fire.
Further, the conventional image in the embodiment of the present invention refers to a color image or a black image, and the higher the true restoration degree (definition) of the image is, the more the real circuit environment condition can be reflected, and the more accurate the result obtained through the analysis processing performed by the analysis processing module 200 is, the infrared ray image capturing is preferred as the capturing mode of the conventional image in the embodiment of the present invention.
