Application case of Intelligent Transportation

The system consists of five units: detection unit, image capture unit, camera unit, license plate automatic recognition unit and network management unit. Detection unit: it mainly adopts the detection mode of speed measuring radar. Camera unit: each lane is monitored by two cameras, one for panoramic shooting and the other for close-up shooting, recording the license plate number. The night lighting adopts CAD constant light source.

The system consists of five units: detection unit, image capture unit, camera unit, license plate automatic recognition unit and network management unit. Detection unit: it mainly adopts the detection mode of speed measuring radar. Camera unit: each lane is monitored by two cameras, one for panoramic shooting and the other for close-up shooting, recording the license plate number. The night lighting adopts CAD constant light source. Image capture unit: the unit is composed of an industrial computer and special software, which mainly completes image capture, traffic flow calculation, speed calculation and other tasks. The image captured by the system is stored in a special computer on site in the format of BMP file. The special software can enlarge the picture and complete the functions of inquiry, statistics and printing. License plate recognition unit: with the use of automatic recognition software, the vehicle can be checked. When the 'blacklist' vehicle appears, the system will immediately send an alarm signal. Network management unit: control, record query, data exchange and 'blacklist' data refresh of front-end equipment through special software and remote communication network. With broadband communication lines such as optical fiber, image capture unit can be transplanted to remote monitoring center

System functions:

1. Vehicle detection record: monitor and record the vehicle type, color and license plate of every passing vehicle 24 hours a day, and automatically recognize the license plate number, refresh the database automatically, and record circularly.

2. Speed measurement function: the system can accurately detect and record the driving speed of passing motor vehicles every day. When there are speeding vehicles, the system will automatically alarm and record the photos together with the speed data into the violation database.

3. Traffic flow detection and Statistics: provide accurate traffic flow statistical data in hours, and provide traffic management departments with traffic flow reports in a direct square.

4. Blacklist vehicle inspection: the system automatically recognizes the license plate of each close-up picture of vehicle, and quickly compares the recognition result with the blacklist license plate. If there is the same, the system will immediately alarm and display the license plate number and the type of blacklist license plate.

5. Remote communication and management function: with remote communication line, the front-end equipment can be controlled by the computer in the monitoring center, and the blacklist database can be updated at any time, and the image data and traffic flow data in the front-end database can be transmitted back to the monitoring center.
