Description

Monitor camera device

Technical field

This utility model belongs to monitor camera device field, especially relates to a kind of prison for night traffic monitoring camera Control camera head.

Background technology

Present stage night movement vehicle license plate identification is mainly auxiliary by bayonet socket camera, electronic police (essence is still bayonet socket camera) Helping flash lighting to realize, but both the above equipment price is high, mounting process is complicated, is not suitable for extensive universal, it is impossible to reach The requirement of all standing is monitored to safe city.Common high definition monitoring camera identifies that moving vehicle car plate relies primarily on Chang Liang night Light source light filling, but vehicle strong illumination cannot be suppressed, solving picture conditions of streaking, discrimination is extremely low.Tradition light compensation method uses , all there is power consumption big in Halogen light (more than power 500W), LED white light (more than power 80W), it is impossible to suppression vehicle high light, Cannot solve moving vehicle picture conditions of streaking, Car license recognition rate is low.Halogen lamp light color is unfavorable to Car license recognition, discrimination Being only capable of reaching 30%, car plate definition is the highest, and service life is short, and power consumption is high, and caloric value is big, starts moment to monitoring system System impact is big, easily causes equipment failure rate and raises.Power 80W above LED white light is favourable to Car license recognition, but LED light Concentrating, skewness, light beam mid portion is brighter, substantially shades in both sides, can only identify light beam brighter position car plate, it is impossible to cover Cover whole road surface, it is impossible to suppression vehicle high light, it is impossible to solve moving vehicle picture conditions of streaking, discrimination is less than 50%, car plate Definition is permissible, but lamp from dazzling, easily cause vehicle accident, do not meet traffic safety code requirement.

Patent 201220656533.1 discloses a kind of new road monitor camera device, including photographic head, on photographic head Connecting and have image processing apparatus, image processing apparatus connects data storage device, photographic head connects second camera device, Second camera device includes sensing device and light compensating apparatus, and sensing device is connected with photographic head with light compensating apparatus.This novel road Road monitor camera device, it is possible to increase shooting precision and shooting picture quality.

There is energy consumption height in the monitor camera device of prior art, the problems such as conditions of streaking easily occur in poor stability, picture, How to use a kind of monitor camera device and method night, both can suppress vehicle strong illumination, moving vehicle can be identified again Car plate, is the difficult problem in monitoring trade, does not has successful case the most so far, along with the intelligent good application of high-definition monitoring, Social need is more urgent.

Utility model content

The purpose of this utility model is to provide a kind of monitor camera device of vehicle license plate in identification motion at night, carries High car license plate recognition rate, reaches the license plate intelligently retrieval requirement to image definition, reduces monitor camera device light compensating lamp Power, driver safety can also be protected while energy-conserving and environment-protective to drive.

The technical solution of the utility model is:

Monitor camera device, including monitoring camera and the LED light supplement lamp installed in the same direction with monitoring camera, LED light filling Lamp includes procapsid, back casing, is arranged on the circuit control module within back casing and is arranged on the LED within procapsid Lamp, the front end of procapsid is provided with reflector and optical transmission window, and circuit control module is connected by electric wire with LED, described Light window matches with the outlet of reflector setting, and described optical transmission window is provided with convex lens, and the power of described LED is 5- 50W, the sidewall of back casing is fixed with extraction spool, and the part that extraction spool is positioned at outside rear shell side wall is provided with external screw thread, One end of lead-out wire is connected through drawing spool with circuit control module, and the extraction spool outside rear shell side wall is provided with and draws The locking nut that outlet-pipe external screw thread matches, the extraction spool of back cover interior is coated with sealant layer.

The LED light supplement lamp of this utility model monitor camera device uses the convex lens matched with optical transmission window, convex lens Match with reflector to concentrate the light dissipated emitted by LDE lamp and become parallel rays, make the light in range of exposures divide Cloth is uniform, and brightness is consistent.The present utility model people finds through numerous studies, LED and the convex lens using power to be 5-50W Mirror combination can either meet the requirement of number plate of vehicle identification, again it can be avoided that light is too strong, causes picture conditions of streaking.And this The source light that the LED light supplement lamp of utility model monitor camera device is provided is soft, driver in driving procedure, driver Consistent with the light luminance that LED distance does not exists together, driver's sight line will not be affected due to light change, cause security incident.
