The invention relates to a method and system for filtering out interference from small heat sources of infrared detectors. The method includes: classifying the energy of the object to be measured, determining the level triggering event according to the waveform appearing in the sensor, and triggering the event according to different levels Screen and filter out the interference of small heat sources; according to the different ability of heat sources to penetrate the air at different ambient temperatures, the energy of the waveform of the same heat source moving through the lens sheet to the sensor is different to obtain the temperature compensation formula, and the deviation compensation value is obtained for the environment. The infrared sensor is compensated, and the compensated value ΔV is obtained pb . The invention has the advantages that: the detection distance of the infrared detector can be made longer, the anti-interference ability of small heat sources becomes stronger, the sensitivity is improved, and the detection sensitivity at different temperatures can be kept consistent; False alarms caused by interference such as temperature and temperature make the infrared detector energy-saving and reliable, thus fundamentally solving the problem of many false alarms of ordinary detectors.
Description
