To exclude abnormal overheating of the object to be tested. It is well known that for the same object to be tested, the temperature data obtained by the user holding the infrared camera to detect the object to be tested is subject to the detection distance between the user and the object (because of the intensity and distance of the heat radiation) The square is inversely proportional to the effect of detecting the angle and there is a significant difference in temperature reading. The conventional solution is, for example, to fix the infrared camera to a same shooting position by using a fixed tripod to reduce the difference in shooting position. The resulting measurement difference.

However, in order to detect whether the temperature of the switchboard in the high-tech factory is abnormal, if the inspector is required to carry a fixed tripod and an infrared camera in the factory area, it will cause inconvenience to the inspectors.

The control unit is electrically connected to the identification unit, and the control unit transmits at least one of the visible light image, the heat distribution image, the plurality of temperature data, and the current feature to the server 30 according to the identification signal, wherein the thermal image sensing unit 10 continues to transmit the detection. The data R is transmitted to the mobile device 20, but the mobile device 20 transmits the detected data R to the server 30 when the identification signal indicates that the current feature matches the historical feature.

In an embodiment, the current feature includes, but is not limited to, a pattern, a contour, or a feature point of the object to be tested in the visible light image. For example, one of the surface of the object to be tested in the visible light image has a nut pattern or a flange of the nut, which may be a current feature; or based on a plurality of brightness values of a plurality of pixels in the visible light image, by calculation Method, calculate multiple feature points, but not limited to this.
