An infrared laser beam detector

Abstract

The invention provides an infrared laser opposite emission detector. The infrared laser opposite emission detector detects whether a pulse laser beam affecting emission of an infrared laser opposite emission projector is normally emitted towards an infrared laser opposite emission receiver in a wide climatic environment, and output signals are potential-free contacts. The infrared laser opposite emission detector is composed of the infrared laser opposite emission projector and the infrared laser opposite emission receiver. According to the infrared laser opposite emission projector, an infrared laser emitter is controlled by an infrared laser opposite emission projector single-chip microcomputer to emit the pulse laser beam. According to the infrared laser opposite emission receiver, a single-chip microcomputer processes the pulse laser beam and outputs potential-free contact normally open / closed signals.

Description

technical field [0001] The invention relates to an infrared laser beam-to-beam detector in the field of security technology prevention, which is applied to surrounding alarms. Background technique [0002] In the field of security technology prevention, the common infrared radiation method has been widely used. However, infrared radiation detectors using ordinary light sources have defects such as non-concentrated infrared light energy, large divergence angle, weak penetration ability, and high emission power consumption. Disadvantages such as high false alarm rate, large crosstalk, and high infrared power in the case of long-distance shooting. The following technical problems exist in the infrared through-beam detectors using ordinary infrared light sources: (1) There is crosstalk between adjacent infrared through-beam detectors; The weather; (3) The shooting distance is short, and it cannot adapt to the long-distance shooting; (4) The transmission power is large and the ...

The following technical problems exist in the infrared through-beam detectors using ordinary infrared light sources: (1) There is crosstalk between adjacent infrared through-beam detectors; The weather; (3) The shooting distance is short, and it cannot adapt to the long-distance shooting; (4) The transmission power is large and the energy consumption is high, which is not conducive to energy saving;

[0003] In addition, the control of the laser beam direction of some existing infrared laser beam detectors is complex, and the beam emission direction is realized by multi-point adjustment, and the adjustment of the vertical direction and the adjustment of the left and right directions interfere with each other

In the debugging process, there are disadvantages such as difficult control of the optical path, complicated debugging, and poor controllability, which reduce the efficiency of debugging
