Embodiment Construction

[0009] After the security engineering construction is completed, adjust the laser adjustment frame so that the laser is irradiated on the laser receiving area (such as figure 1 As shown), assuming that the laser irradiation point is shifted to the upper part of the laser receiving area, then under the laser irradiation, the upper displacement sensor will send a switch signal to the PLC controller of the intelligent adjustment laser control unit, and the PLC controller is set by software program Analyze and process the received upper displacement switch signal, control the action of the upper and lower stepping motors, the rotor rotates at a set fixed angle, after the ratio gear is reduced, adjust the laser to move down a set small distance, and then The PLC controller reads the switching signal of the displacement sensor again. If the upper displacement sensor is still irradiated by the laser and sends a switching signal, it will continue to control the action of the upper and ...

Abstract

The invention relates to an automatic laser seeking calibration device for a laser intrusion detector, which is composed of a laser transmitting end two-dimensional adjustment unit, an intelligent adjustment laser control unit and a laser receiving end laser displacement sensing unit, wherein the laser receiving end laser displacement sensing unit receives a laser irradiation position signal, the signal is transmitted to the intelligent adjustment laser control unit, data analysis is carried out by a PLC in the control unit, a stepper motor in the laser transmitting end two-dimensional adjustment unit is controlled to adjust the laser irradiation position in real time, laser calibration closed-loop control is realized, and the purpose of automatic laser seeking calibration is achieved. The automatic laser seeking calibration device has the advantages that the problem that laser can not be received due to micro deformation generated as a bearing body is subjected to external factors for a long time is solved, continuity of security work can be ensured, and after-sales maintenance fee after the project is finished is saved.

Description

technical field [0001] The invention relates to a detector used in security engineering, in particular to a laser automatic light-seeking calibration device for a laser intrusion detector. Background technique [0002] Laser intrusion detectors are widely used in security projects of various industrial and mining enterprises due to their high emission power density, small divergence angle, strong adaptability to harsh weather environments, small transmission attenuation and long distance. Laser intrusion detectors generally include a laser emitting end and a laser receiving end, which adopt an all-metal structure and are directly fixed on the wall, the side bracket of the wall, and the ground. There is a problem, when the wall, bracket and Under the long-term influence of external factors (such as temperature difference, humidity, etc.), the carrier such as the ground will produce slight deformation, because the laser propagates along a straight line, and the distance betwee...
