Description

Intelligent video identification monitoring and alarming system

Technical field

The utility model relates to a kind of warning system, particularly a kind of intelligent video identification monitoring and alarming system.

Background technology

Infrared monitoring and warning system are to utilize infrared sensor to remove to survey object, judge and warning thereby cause.That mainly uses now has two classes: subtend type infrared ray blocking detector and passive-type pyroscan.In the middle of the blocking detector of infrared mode, two kinds of subtend type and reflection-types are arranged.On principle of work, emission type blocking detector just can not use when the warning distance surpasses 10 meters.To guard against in the periphery in place for building, need long warning distance, therefore, all adopt the subtend type.Subtend type infrared ray blocking detector has utilized the infrared ray of near infrared ray field (0.72～1.5 micron) wavelength, but it is longer than wavelength of visible light, so decay is little in atmosphere, and, it departs from the visible region, and therefore, it did not attract attention in night yet.The passive-type pyroscan has utilized thermo-electric device, its can inspected object 10 microns of the emission energy variation of far infrared field wavelength nearby.Its principle of work is, poor (variation) of the house ambient temperature of warning and the mobile object surface temperature variation as far-infrared ray power, optically focused here amplifies and surveys processing is changed into electric energy by luminous energy signal on thermo-electric device.There is fatal weakness in infrared sensor at technological layer: (1), be subjected to multiple factor such as animal heat radiation, solar radiation, hot stream temperature radiation easily and disturb and cause false alarm.Though this series products constantly adopts two mirror technology, double base or technology such as polytechnics, single-chip microcomputer compensation to improve, and can't solve the false alarm problem all the time at all.(2), when temperature and human body temperature are close to or higher than human body temperature, this class detector will at all can't operate as normal.In light of this situation, infrared detection and warning system also have many will the improvement and perfect place

Summary of the invention

In order to overcome existing monitoring and the existing technical matters of warning system, the utility model provide a kind of simple in structure, discrimination is high, the intelligent video of good stability identification monitoring and alarming system.
