Abstract
The invention provides an intelligent dynamic heat source shielding system based on an infrared thermal imager and a method thereof. The system comprises the infrared thermal imager, a server and a client side. The infrared thermal imager is used for acquiring thermal imaging of an area to be detected and generating corresponding thermal imaging signals. The server is used for acquiring the number of times of continuous repeated emergence of a heat source at the same position within a preset period of time when existence of the heat source is detected in the thermal imaging signals. Whether the number of times reaches a preset alarm number of times is judged. If the judgment result is yes, the heat source is judged to be a fixed heat source, and a fire source alarm signal is transmitted to the client side; or the heat source is judged to be a moving heat source, the heat source is shielded and alarm is not performed. A situation that certain dynamic heat sources which are not fire sources are mistakenly judged as the fire sources can be avoided so that false alarm and omission alarm can be reduced.
