seven functions of license plate recognition system < / a >

I. monitoring alarm

For vehicles included in the "blacklist", such as vehicles wanted or reported missing, vehicles in arrears of payment, vehicles without annual inspection, hit and run vehicles and illegal vehicles, just input their license plate number into the use system, and the license plate recognition equipment shall be installed at the designated intersection, checkpoint or carried by law enforcement personnel at any time and placed as needed, The system will read the license plate number of all passing vehicles and compare it with the "blacklist" in the system. Once the specified vehicle is found, it will immediately announce the alarm information

II. Punishment for speeding violation

License plate recognition skills combined with speed measuring equipment can be used to punish vehicles for speeding violations. Specific use: set speed measuring monitoring points on the road, capture speeding vehicles and identify license plate numbers, and send license plate numbers and pictures of illegal vehicles to all exits. Use the license plate recognition equipment to identify passing vehicles and compare the number with the number of speeding vehicles received. Once the number is the same, start the warning equipment and notify the law enforcement personnel to deal with it. Compared with the traditional overspeed monitoring method, this use can save the police force, reduce the operation intensity of law enforcement personnel, and is safe, efficient and hidden. Drivers need to remind themselves not to overspeed at all times, which greatly reduces the accidents caused by overspeed

III. handling of vehicle revenue and expenditure

The license plate recognition equipment is installed at the revenue and expenditure port to record the license plate number and revenue and expenditure time of the vehicle, and combined with the control equipment of the active door and road gate to complete the active handling of the vehicle. It can be used in the parking lot to complete the active timing charge, and can also take the initiative to calculate the number of available parking spaces and give tips to complete the active handling of parking charge, so as to save manpower and improve power. When used in an intelligent community, it can actively judge whether the incoming vehicle belongs to the community, and complete the active timing charge for Non internal vehicles. In some units, this use can also be combined with the vehicle dispatching system to actively and objectively record the departure status of their vehicles. The license plate recognition skill is selected in the traffic management system to achieve no parking and no card collection, which can effectively improve the traffic power of vehicle revenue and expenditure

IV. active release

Input the specified license plate information into the system, and the system actively reads the license plate of passing vehicles and queries the internal database. For vehicles requiring active release, the system drives the electronic door or railing machine to let them pass. For other vehicle systems, warnings will be given and handled by the personnel on duty. It can be used in special units (such as military management area, confidentiality unit, key protection unit, etc.), road and Bridge toll gate, senior residential area, etc

V. expressway toll handling

License plate recognition equipment is installed at each revenue and expenditure port of the expressway. When the vehicle enters, it recognizes the vehicle license plate, stores the entrance data into the charging system, recognizes the vehicle license plate again when the vehicle arrives at the exit, calls the entrance data according to the license plate information, and completes the charging process in combination with the revenue and expenditure port data. This use can complete active billing, prevent fraud and avoid the loss of accounts receivable

The expressway has begun to implement network charging. With the expansion of network scale, the charging difference of different models is becoming higher and higher. The problem of drivers using the loopholes of the existing charging system to evade fees by changing cards halfway will become more and more outstanding. The use of license plate recognition skills is the fundamental method to deal with this kind of problem

Vi. calculate vehicle tour time

In the traffic management system, the uniform travel time of vehicles on a certain road can be used as a parameter to judge the congestion on the road. Install license plate recognition equipment at the starting and ending points of the road, read all passing vehicles and send the license plate number back to the traffic command center. The management system of the command center can calculate the average travel time of vehicles according to these results

VII. Active registration of license plate number

The traffic supervision department processes a large number of pictures of illegal vehicles every day. Generally, the license plate number is manually identified and then input into the management system. This method has a large amount of work and is easy to fatigue and misjudge. The selection of active recognition can reduce the operation intensity and greatly improve the processing speed and power
