Intelligent Highway Toll System in Henan Province

For. And the number of cumulative adoption. Step four: intelligence monitoring platform database regularly by the smallest number of vehicles. To ensure that less than a certain number of data. To improve the degree. ● on the free car. Military police vehicle. Black car I first step: monitoring staff enter the road car. Black car. Or through automatic text database. Step Two: When a vehicle through the export of cars enter the contingent fee free car class members will be charged automatically check the appropriate database monitoring system. When they find the library has not the time relative to the license plate number, intelligent monitoring platform will immediately send a message to the appropriate lane UTP computer, to remind the re-determine the toll, while the pop-up images for monitoring staff to determine the vehicle. Step three: When a vehicle checkpoints, the inspection system automatically captured pictures and license plate number of vehicles recorded. When the vehicle the next time through, automatic alarm and alert toll. Intelligent monitoring systems management platform is the toll station staff to the operation by monitoring the need to do the following: official vehicle. Blacklist entry of vehicles should be able to monitor members of the public service vehicles under this section to change the blacklist to delete the appropriate vehicle to join the car class table. Warning letters risk of treatment when there is alarm sounds, the monitoring staff should be able to judge based on tips and image anomalies occur, and through the intercom and command verification toll accordingly. Kids in the entire system architecture system topology local area networks linked together by system equipment. Among them, the intelligent control platform for analysis and processing to store the data independently to facilitate system maintenance. Upgrade. System Topography reflects a toll station on the intelligent monitoring system connection between the main equipment. Plotted in the figure only a pair of import and export of equipment, other equipment import and export connection do the same repeat. The main components of the system introduced. Car vehicle license plate recognition device identifier (referred to as the license identifier) is the core of the system. License plate recognition is mainly by the capture unit and processing unit. Mainly by providing the license number of the machine recognition results. License plate recognition provides a standard RS232 serial port and a 10/1OOM adaptive network port, easy connection with external devices. o Intelligent Surveillance platform is composed of software and database management system intelligent monitoring platform. Platform software for data analysis of the main processing and human-computer interaction. Database management system used to store business data. o lu Jiang heavy data flow data (red thick grasshopper that only part of the exit lane with this feature t) garlic loving!} i ridicule data flow diagram describes two intelligent control platform for the entire data flow. Drive machines and license plate recognition device monitoring platform, the dynamic link library are used to exchange data. Billing software dynamic link library by calling the corresponding function can be done to understand the function of the phase, regardless of the data transmission processing after the data to the monitoring platform through a series of analysis, processing judging process will determine the final results back to the Drive Machine . Therefore, the charging system and the relationship between monitoring platform can be summarized as: Enter the data collection system,[link widoczny dla zalogowanych], waiting to judge the results; monitoring platform for analysis and processing to determine data. Data flow throughout the monitoring system can be divided into entry and exit data flow data flow. The data entry process is relatively simple. When a vehicle through the lane, license plate recognition device to identify the license number and the binary images available to the lane machine via the serial port,[link widoczny dla zalogowanych], the lane machine license number and the binary image is written to the access card. Drive machine to the license plate number while the vehicle image binarization image through the interface functions to the intelligent monitoring platform. Export license to export the license identifier information transmitted to the lane machine, while lane machine credit card will be the result of artificial sub-type of access card entry information (including time,[link widoczny dla zalogowanych], license plate number of vehicle entry points binary images, etc.) and export the results of license plate recognition , sent over the network to the intelligent control platform for processing. Finally, the monitoring platform to return to the lane machine to determine the results of a string of code,[link widoczny dla zalogowanych], Drive unit can determine the results of code execution related operations. Write access card at the entrance on the binary image is mainly used to distinguish the secondary than the license plate number. Since the license identifier recognition rate of the entire card can not be 10O%, while the call at the exit of vehicles at the entrance picture is not very convenient, so the license plate at the entrance to the binary image stored in the access card. If the license number at the exit than on the failure,[link widoczny dla zalogowanych], you can use our image alignment algorithm for automatic import and export license images for comparison. License images can also be provided to the manual interpretation of the license number. Conclusion Expressway Network charges inevitable trend of development of a highway as a toll charge management first-line units stations, how to be more scientific, rational and efficient management of the business to charge, we have to face. License plate recognition technology, making it possible for intelligent monitoring. As technology advances, integrated intelligent management system is the inevitable trend of future development.
