A laser three-dimensional anti-intrusion monitoring system

Abstract

The invention relates to a laser stereo-intrusion-prevention monitoring system. The laser stereo-intrusion-prevention monitoring system comprises a power supply, a remote controller, a main controller, a laser emitter, a laser receiver and at least three optical lenses. The optical lenses are used for changing laser routes. The power supply is connected with the main controller, the laser emitter and the laser receiver. The main controller is connected with the remote controller, the laser emitter and the laser receiver. The optical lenses are distributed and arranged in a space. The remote controller is used for transmitting a control instruction to the main controller. The main controller is used for controlling the laser emitter to emit a code-modulated laser beam. The laser beam is received by the laser receiver after being reflected or refracted by the optical lenses and forms a stereoscopic enclosed space surrounded by a laser protection net. When an object intrudes into the stereoscopic enclosed space, an optical path is obstructed, the laser receiver cannot receive a correctly coded laser beam, and the main controller triggers an alarm. Compared with the prior art, the laser stereo-intrusion-prevention monitoring system has the advantages of high reliability, convenience in operation, low cost and the like.

Description

technical field [0001] The invention relates to an anti-theft and monitoring system in the security field, in particular to a laser three-dimensional anti-intrusion monitoring system. Background technique [0002] With the improvement of people's safety awareness, the alarm is widely used in the fields of access control, industrial production, civil control, automatic detection and anti-theft. At present, infrared alarms are used the most. However, in practice, it is found that infrared alarms often have false positives and false negatives. 2. Infrared alarms are susceptible to false alarms due to environmental factors such as temperature and light. 3. The power supply system of the infrared alarm is short of power. When the power is low, there is no effective information transmission, which makes the detection distance of the infrared alarm shorter or does not work, resulting in false alarms and false alarms. In order to solve the above problems, a monitoring system of da...

At present, infrared alarms are most used. However, in practice, it is found that infrared alarms often have false positives and false negatives.

2. Infrared alarms are susceptible to false alarms due to environmental factors such as temperature and light

3. The power supply system of the infrared alarm is short of power. When the power is low, there is no effective information transmission, which makes the detection distance of the infrared alarm shorter or does not work, resulting in false alarms and false alarms.

The disadvantage of this device is that every time the laser changes its direction, a set of laser fiber couplers needs to be installed, which has a complex structure and high cost
