In the process of rapid growth of urban vehicles, how to achieve effective management of vehicles has become an important factor to test the traffic department. License plate recognition technology has become the main means of vehicle identification. So, how to realize license plate recognition technology? What are the main application scenarios of license plate recognition?
License plate recognition implementation
The working mode of peripheral trigger refers to using coil, infrared or other detectors to detect the passing signal of the vehicle. After the vehicle trigger signal is received by the license plate recognition system, the vehicle image is collected, the license plate is automatically recognized and follow-up processing is carried out.
Video trigger mode refers to the license plate recognition system using dynamic moving target sequence image analysis and processing technology, real-time detection of vehicle movement on the road, the detection of vehicle image when the vehicle passes, identification of vehicle license plate, and subsequent processing. Video triggers do not require coils, infrared or other hardware vehicle detectors.
Monitoring and alarm
For vehicles into the "black list", for example: wanted or report the loss of vehicles, owe fee, not yearly check of vehicle, hit-and-run and peccancy vehicles etc., need to apply the license plate number input to the system, the license plate recognition device installed in the specified intersection, bayonet or carry placed, as required by law enforcement personnel system will read all through the vehicle's license plate number and with the "blacklist" than in the system, once found designated vehicle immediately send out alarm information.
Speed measurement monitoring points are set up on the road to capture speeding vehicles and identify license plate Numbers, and the license plate Numbers and pictures of illegal vehicles are sent to each exit; Set penalty points at each exit, identify passing vehicles with license plate recognition equipment and compare the number with the number of speeding vehicles already received. Once the number is the same, the warning equipment will be activated to inform law enforcement personnel to deal with it.
Vehicle access management
The license plate recognition equipment is installed at the entrance and exit to record the license plate number and access time of the vehicle, and combined with the automatic door and railing machine control equipment to achieve automatic management of the vehicle. When applied to parking lots, automatic timing and charging can be realized, and the number of available parking Spaces can be automatically calculated and given hints, so as to realize automatic management of parking fees, save manpower and improve efficiency. Applied to intelligent community, it can automatically determine whether the incoming vehicle belongs to this community, and realize automatic timing and charging for non-internal vehicles. In some units this application can also be combined with the vehicle dispatching system, automatically and objectively record the vehicle out of the unit, license plate recognition management system USES license plate recognition technology, achieve no parking, no card, effectively improve the efficiency of vehicle access.
Highway toll management
License plate recognition equipment is installed at each entrance and exit of the expressway. When the vehicle enters, it recognizes the vehicle license plate and stores the entry data into the charging system. When the vehicle arrives at the exit, it recognizes the license plate again and invokes the entry data according to the license plate information. This application can achieve automatic billing and can prevent cheating, avoid the loss of receivables.
Expressway has begun to implement the network toll, with the expansion of the network scope, the difference between different models of the toll is also increasingly high, the problem of drivers using the existing toll system loopholes through the midway card to escape the problem will be more and more prominent, the use of license plate recognition technology is the fundamental method to solve such problems.
Calculate the vehicle travel time s
In the traffic management system, the average travel time of vehicles in a certain road can be taken as a parameter to judge the road congestion. License plate recognition equipment is installed at the starting and ending points of the road, which can read all passing vehicles and send the license plate number back to the traffic command center. Based on these results, the management system of the command center can calculate the average travel time of vehicles.
In addition, with the rapid growth of urban population, the rapid increase of vehicle ownership and the implementation of government regulations, the electronic charging system is expected to drive the growth of license plate recognition market. According to the survey, license plate recognition systems in the asia-pacific region will grow at an annual rate of 18.06 percent, the highest among other regions, to cope with the rapid growth in traffic congestion, police enforcement, toll collection and parking.
