A working method of a laser wall security device

Abstract

A laser wall security device of the invention is characterized by comprising a laser ranging instrument, a turntable component, a laser ranging control system, a power supply system and a signal output end. The operation method of the laser wall security device is characterized by comprising the following steps of setting the rotation range of the turntable component; setting the scanning area; calculating a real-time theoretical laser distance LP; comparing an actual laser distance LS with the theoretical laser distance LP, and when LS<=LP, the laser ranging control system outputs an alarm signal and real-time information of an invasion object to the signal output end. The laser wall security device and the operation method thereof have advantages of large alarm range, high alarm sensitivity, high identification capability, small number or error reports, high adaptability, etc.

Description

technical field [0001] The invention relates to the field of safety protection technical equipment, in particular to a laser safety protection device. Background technique [0002] With the requirements of the society on the security situation and the demand for security protection in various fields, laser security devices are playing an increasingly important role in the security field. The laser security device is a device that uses physical methods or electronic technology to automatically detect intrusions that occur in the armed monitoring area, generate an alarm signal, and assist the personnel on duty to indicate the area where the alarm occurred, and display the equipment that may take countermeasures. [0003] Laser security devices are also widely used in power systems. Due to the rapid development of the national economy and the continuous expansion of the city scale, the transmission lines are becoming more and more dense, and the operating environment is becomi...

Problems solved by technology

However, because the video surveillance alarm device uses a camera to obtain the signal of the intruding object, the acquisition of the signal will be greatly affected by the external environment and the status of the intruding object.

Simply put, when the weather is bad and the visibility is low, the alarm recognition of the video surveillance alarm device will be greatly reduced; when the intruding object is small, or the appearance of the intruding object is similar to the external environment, the alarm will not be timely.
