Abstract
The invention relates to the field of traffic control technique, especially, an electric police system and method. The system consists of CCD camera, video acquisition control card. The CCD camera isused for video record and grasp shoot of vehicle; the video acquisition control card is mounted in the intersection computer used to receive the images of CCD camera and handle the images and completethe license plate identification, images preservation and transmission. The realizing method is: the CCD camera monitors the vehicles from four directions, when the vehicles rush the red light, the signal of grasp shoot is sent to the video acquisition control card by intersection computer, the video acquisition control card grasps the vehicles rushing red light, the license plate can be identified according to the images between a little time when the vehicles rush the red light grasped by the CCD camera, and then the grasped images and identified license plate are sent to the control centerof intersection computer, and the signal is sent to the traffic control center by the main control center of intersection computer.
Description
Technical field
The present invention relates to the traffic management technology field, particularly a kind of electronic police system and method thereof.
Background technology
Traditional electronic police system carries out field control by special industrial computer, and it is two entities that separate with junction machine.Our its principal feature of designed electronic police system is to be installed in the casing with junction machine, thereby has saved the cost that traffic signaling equipment and electronic police system are installed simultaneously at the crossing.
Summary of the invention
Purpose of the present invention provides a kind of electronic police system.
The major function of this electronic police system is to realize rushing the candid photograph of red vehicle and car plate identification and by junction machine the photo of capturing and its car plate are sent to traffic control center well.
Electronic police system is made up of CCD camera, video frequency collection card, junction machine, communication unit, RS-232 Serial Port Line.The CCD camera is used for vehicle is recorded a video and captured; The video acquisition control card is installed within the junction machine, thus be used to receive the image of CCD camera and image handled finish car plate identification, image (photo) is preserved and the function of transmission.
The CCD camera links to each other with video frequency collection card within being installed in junction machine by common cable, and video frequency collection card links to each other with the junction machine master control borad by serial ports.
System operating mode is as follows:
The CCD camera is monitored to vehicle the four directions, crossing, when vehicle makes a dash across the red light, junction machine sends the candid photograph signal for the video acquisition control card, video frequency collection card is captured rushing red vehicle, and the front and back of making a dash across the red light according to the vehicle that the CCD camera transmits in a bit of time image recognition go out to rush the license plate number of red vehicle, then the license plate number of vehicle red light running image and identification is sent to the junction machine main control centre, this information is sent to traffic control center by the junction machine main control centre.

Fig. 1 is an electronic police structural representation of the present invention.
Fig. 2 is an electronic police system composition diagram of the present invention.
Fig. 3 is an electronic police workflow diagram of the present invention.
Embodiment
In Fig. 1, video frequency collection card is inserted within the casing, is connected to communication unit by pci bus.Communication unit communicates by RS-232 data line and junction machine master control borad.Power supply is provided by the junction machine general supply, and whole box body and junction machine discharge up and down, places jointly within the rack of depositing junction machine.
Fig. 2 electronic police system, electronic police system is made up of CCD camera, video frequency collection card, junction machine, communication unit, RS-232 Serial Port Line.The CCD camera is used for vehicle is recorded a video and captured; The video acquisition control card is installed within the junction machine, thus be used to receive the image of CCD camera and image handled finish car plate identification, image is preserved and transmission.The CCD camera links to each other with video frequency collection card within being installed in junction machine by common cable, and video frequency collection card links to each other with the junction machine master control borad by serial ports.
Wherein, CCD camera, video frequency collection card, junction machine, communication unit, RS-232 Serial Port Line all belong to general, conventional model.
Fig. 3 electronic police workflow, its concrete steps are as follows:
Step S1, the CCD camera is monitored the vehicle at crossing, and the image of vehicle is sent to the video acquisition control card, and the video acquisition control card is preserved 5 minutes nearest video recording;
Step S2 when junction machine has detected vehicle and makes a dash across the red light, sends to video frequency collection card rushing red signal and rushing the residing number of track-lines of red vehicle;
Step S3, video frequency collection card receives that junction machine sends over when rushing red signal, rush the residing number of track-lines of red vehicle and will rush the image of red vehicle and preserve according to what pass over simultaneously, according to image the license plate number of rushing red vehicle is discerned simultaneously, and the license plate number and the image of identification are sent to the junction machine master control borad together;
Step S4, the junction machine master control borad is sent to traffic control center receiving data.
