Shutdown circuit is opened to supplementary light intelligence of infrared camera machine

The utility model discloses a shutdown circuit is opened to supplementary light intelligence of infrared camera machine, including pyroelectric infrared sensor, and the signal amplifier who is connected with pyroelectric infrared sensor output electricity, and the minimum system of singlechip that is connected with the signal amplifier electricity, and singlechip minimum system electric connection's LED driver, reach with the electric infrared lamp of being connected of LED driver. The utility model discloses a shutdown circuit is opened to supplementary light intelligence of infrared camera machine, hardware circuit is simple, and stability is good, and the minimum system of singlechip is sent into through taking care of to the signal of postdetection, and the error rate is little, can open infrared supplementary light when being necessary and throw light on, reduce in the time of non - the needs or close the auxiliary illumination lighting system, reduce extra energy losses with this.
