Claim 0:
1. A thermal detection system, comprising:
a thermal detector, comprising a thermal sensor array, the thermal detector being configured to detect thermal radiation within a detection area around the thermal detector, the detection area being defined by a field of view of the thermal sensor array;
an area indicating unit, arranged to indicate a human-perceptible area according to the detection area, wherein the human-perceptible area comprises a visible area; the visible area is located within the detection area and indicates a geometric form of the detection area; and
a control unit, coupled to the thermal detector and the area indicating unit, the control unit being configured to generate a thermal detection result according to the detected thermal radiation;
wherein the detection area is located on a reference surface below the thermal detector;
the thermal detection system further comprises:
a base structure, fixed relative to the reference surface;
an arm structure, connected between the base structure and the thermal detector, wherein the arm structure is flexible to allow relative movement between the thermal detector and the reference surface to adjust the detection area; and
a notification unit, coupled to the control unit, the notification unit being configured to generate a notification signal according to the thermal detection result so as to indicate an overheating condition;
wherein the control unit comprises:
a memory, configured to store the thermal detection result; and
a processing circuit, coupled to the notification unit and the memory, wherein when the thermal detection result indicates that a temperature at a first location on the detection area is greater than or equal to a first threshold value, or indicates that a rate of change of the temperature at the first location is greater than or equal to a second threshold value, the processing circuit is configured to determine if an object is passing over the first location according to the thermal detection result stored in the memory; when the processing circuit determines that the object is passing over the first location, the notification unit is configured to generate the notification signal to indicate that the overheating condition occurred at the first location.
