Method and system for improving ash deposition resistance of smoke fire detector

The invention discloses a method and a system for improving ash deposition resistance of a smoke fire detector, relates to the technical field of fire alarm, and solves the technical problems that the alarm reliability of the detector is reduced due to ash deposition in an optical darkroom of the detector, and the fire risk cannot be warned in time. The initial state of the detector is adjusted to be a high-sensitivity state, the smoke concentration is detected regularly, the background value is updated, then the working state of the detector is adaptively adjusted according to the detection result and the background value of the detector, and finally the fire is alarmed according to the smoke concentration. The influence of detector optical darkroom dust deposition on the working state of the photoelectric smoke fire detector is reduced, so that the period of cleaning the detector is prolonged, and manpower and material resource consumption is reduced. 本发明公开了一种提高感烟火灾探测器抗积灰性能的方法和系统，涉及消防报警技术领域，解决了探测器光学暗室积灰导致探测
