Abstract
The utility model discloses a vehicle license plate recognition device, comprising a video acquisition module (3), a snapshot module (5), a flash lamp (10), a vehicle detector (9), an image recognition module (6), an RS232 communication module (7), a video decoder (8), the Ethernet (11), and an industrial control computer (12). The snapshot module (5) is connected with the video acquisition module (3), the flash lamp (10) and the vehicle detector (9). The image recognition module (6) is connected with the industrial control computer (12) through the Ethernet (11). An end of the video decoder (8) is connected with the snapshot module (5) through video cables, and the other end is connected with the image recognition module (6). An end of the RS232 communication module (7) is connected with the image recognition module (6), and the other end is connected with the snapshot module (5). The vehicle license plate recognition device uses a split structure, and is advantaged by convenient installation and maintenance, wide work adapting range, and high recognition rate. The vehicle license plate recognition device also has advantages of stable and reliable.
Description
Technical field
The utility model relates to a kind of license plate recognition device, particularly a kind of split type embedded vehicle license plate recognition device.
Background technology
Current, China's highway mileage is also in continuous increase, and the vehicle that operates on the highway also constantly increases.All sail the information of vehicles of highway, particularly license plate number into, and with typing charge and supervisory system, management company provides operation management for Expressway Operation.Because vehicle flowrate constantly increases, the mode of artificial input license plate number does not more and more satisfy the requirement of existing vehicle flowrate and traffic efficiency, automatic car plate recognizer, for Fare Collection System intelligent, robotization provides convenience, can improve greatly charge station's communication efficiency, alleviate artificial car plate typing intensity, reduce the possible errors of manual entry.At present, having had on the market a kind of car plate is identification software, and this running software by being linked into the video image of industrial computer, is finished car plate identification in the lane in which the drivers should pay fees industrial computer.This software recognition method has and installs simply, does not need the advantage of special hardware supported, but it is high also to have track industrial computer system resources occupation rate simultaneously, causes the charging software operation slowly, uses the industrial computer inner video image, image quality is poor, the low deficiency that waits of recognition accuracy.This car plate recognizer adopts the DSP embedded processor, and travelling speed is fast, cooperates the specialized hardware image collecting device, image acquisition is clear, and recognition speed is fast, and discrimination is high, is independent of the charge industrial computer, occupying system resources is not easy to maintenance, is the desirable substitute products of software recognition system.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of convenient for installation and maintenance, reliable and stable, split type embedded vehicle license plate recognition device that discrimination is high.
The technical scheme that the utility model solves the problems of the technologies described above is: a kind of license plate recognition device, comprise video acquisition module, video capture module, flashlamp, wagon detector, pattern recognition module, RS232 communication module, Video Decoder, Ethernet, industrial computer, described video capture module is connected with video acquisition module, flashlamp, wagon detector respectively; Described pattern recognition module is connected with industrial computer by Ethernet, Video Decoder one end is connected with the video capture module by vision cable, the other end is connected with the pattern recognition module, and RS232 communication module one end is connected in the pattern recognition module, and the other end is connected in the video capture module.
Advantage of the present utility model: video acquisition module cooperates flashlamp in the utility model, can capture and obtain clearly image, for the pattern recognition resume module, and identifies fast car plate.The utlity model has and do not take charge industrial computer system resource, discrimination is high, the advantage that recognition speed is fast, and independent self-organizing system, working service is convenient.
Below in conjunction with specific embodiments and the drawings structure of the present utility model is further described.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises video acquisition module 3, video capture module 5, flashlamp 10, wagon detector 9, pattern recognition module 6, RS232 communication module 7, Video Decoder 8, Ethernet 11, industrial computer 2, and described video capture module 5 is connected with video acquisition module 3, flashlamp 10, wagon detector 9 respectively; Described pattern recognition module 6 is connected with industrial computer 12 by Ethernet 11, Video Decoder 8 one ends are connected with video capture module 5 by vision cable, the other end is connected with pattern recognition module 6, RS232 communication module 7 one ends are connected in pattern recognition module 6, and the other end is connected in video capture module 5.
Principle of work of the present utility model: video capture module 5 is connected to wagon detector 9, after wagon detector inspection device 9 measures the predetermined candid photograph position of vehicle arrival, send the vehicle arriving signal to video capture module 5, after video capture module 5 collects this signal, detect immediately video synchronization signal, and according to the candid photograph parameter of internal configurations, 10 flashes of light of trigger flashing lamp, and send the image acquisition instruction to pattern recognition module 6, pattern recognition module 6 is received and is collected immediately the current flash of light width of cloth complete image of moment after this instruction, and this width of cloth image done the identification computing, then recognition result is sent to charge industrial computer 12 by Ethernet 11.
