Unattended low-power-consumption multispectral night vision alarm system

Abstract

The invention discloses an unattended low-power-consumption multispectral night vision alarm system which comprises a thermal infrared imager, a laser night vision device and a network switch, and thelaser night vision device comprises a night vision device main control module, a visible light imaging system, a laser lighting system, a laser power supply module, a night vision device holder and ashort message alarm module. According to the invention, the thermal infrared imager is used for monitoring the high-temperature target intruding into the monitoring area, then the laser night visiondevice is used for accurately positioning, amplifying and centrally displaying the high-temperature target, and then the position of the high-temperature target is sent to the background, so that thealarm information can still be obtained under the unattended condition. The laser power supply module determines whether to supply power to the laser lighting system according to the resistance valueof the photoresistor, the motion state information of the holder and the alarm state information of the thermal infrared imager, thereby reducing the power consumption of the system.

Description

technical field [0001] The invention relates to an unattended low-power multispectral night vision alarm system, belonging to the technical field of security video monitoring. Background technique [0002] With the rapid development of the economy and society and the improvement of people's living standards, more and more video surveillance equipment has entered our lives. In residential areas, schools, shopping malls, stations, etc., video surveillance equipment is everywhere, providing personal and Property security provides a guarantee and greatly facilitates people's daily life. However, in some special occasions, such as areas along railway lines, reservoirs, oil fields, oil pipelines, protected areas, etc., it is necessary to prevent the intrusion of personnel and vehicles at all times. Traditional video surveillance equipment requires personnel to continuously guard the monitoring room, resulting in manpower and material resources. It is a huge waste and it is diffic...

Problems solved by technology

However, in some special occasions, such as along the railway line, reservoirs, oil fields, oil pipelines, protection zone boundaries and other areas, it is necessary to prevent the intrusion of personnel and vehicles at all times. Traditional video surveillance equipment requires personnel to be continuously on duty in the monitoring room, resulting in manpower and material resources. The great waste of it is difficult to meet its use requirements

[0003] Traditional alarm devices such as infrared radiation, microwave radiation, and vibrating optical fibers generally have problems such as high false alarm rate, single alarm information, and inconvenient installation and layout.

In the use of traditional laser night vision devices, the laser is mostly a timing switch or a single photosensitive control switch, which is kept on at night. In this mode, the laser works for a long time, the system consumes a lot of power, and the life loss is fast.
