Car Park License Plate Recognition Management System Is Popular, Do You still Need to Bury Ground In

With more and more high technologies joining the family of parking lots, many traditional parking lot structures are gradually eliminated, and the best embodiment is the license plate recognition technology. The traditional parking lot architecture is dominated by the ground induction coil, and then add the card reading system to get in and out of the parking lot. In this era when the license plate recognition management system is popular, does the parking lot still need to bury the ground induction coil? Let's have a look. License plate recognition system is a special computer vision system aiming at vehicle license plate. License plate recognition system is not only applied in parking lot, but also plays a very important role in traffic field.

It can be said that it is an important part of intelligent transportation system and one of the main functional modules of high-tech highway traffic monitoring and management system. It can be widely used in traffic flow detection, traffic control and guidance, vehicle management in airports, ports and communities, automatic toll collection without parking, red light running and other illegal vehicle monitoring. Compared with the traditional ground sensing parking lot, it has obvious advantages: 1. The advantages of license plate recognition system in vehicle management in parking lot 1) vehicle entry: 1 The vehicle drives into the license plate camera capture area, reads the card and captures the image. 2. The license plate recognition system automatically captures the image of the vehicle and recognizes the license plate identification number, and then obtains the license plate of the vehicle database through searching the database and compares it. 3. For vehicles with unsuccessful license plate comparison, the gate will not be opened, and the system will send an alarm signal to inform the staff to pay attention. 4. The comparison is successful, the gate is released, and the vehicle entry time is recorded at the same time. The whole process is completed automatically without staff intervention. 2) vehicle departure: 1. The vehicle drives into the license plate camera capture area, reads the card and captures the image. 2. The license plate recognition system automatically captures the image of the vehicle and recognizes the license plate identification number, and then obtains the license plate of the vehicle database through searching the database and compares it. 3. For vehicles with unsuccessful license plate comparison, the gate will not be opened, and the system will send an alarm signal to inform the staff to pay attention. 4. The comparison is successful, the gate is released, and the vehicle exit time is recorded at the same time. The whole process is completed automatically without staff intervention.

II. Advantages of the license plate recognition system in the management of fixed vehicles in the parking lot 1. Solve the problem of one card and multiple vehicles in card management; 2. Solve the problem that the card is not carried during card management; 3. Solve the problem of card replacement and replacement caused by card loss or damage during card management; 4. Solve the communication of card installation and placement during card management. III. advantages of license plate recognition system in temporary vehicle management and charging 1. When solving card management, toll collectors have the opportunity to collect money; 2. Liberate the toll collector from the work of manual card issuing, and only need to be responsible for collecting money - even if the entrance card issuing machine is equipped, someone often needs to help transfer the temporary card between the entrance card issuing machine and the temporary car, which often deviates from the initial purpose of saving human resources. Because the temporary car often stops far away from the card issuing machine, which is a subconscious normal reflection of people's fear of hitting the card issuing machine and the road gate; 3. When solving the problem of card management, temporary vehicles may be mixed out of the parking lot and the temporary card and parking fee will be lost at the same time; 4. Solve the problem that individual fixed vehicles maliciously take away temporary cards when entering the site, resulting in the continuous loss of temporary cards; 5. Solve the problem of limited card capacity of the entrance card issuing machine; 6. Automatically distinguish the models of crane and trolley, and implement different charging standards. The ground induction coil is generally used to detect the existence of vehicles. Its principle is that the oscillation is stable and reliable.

The oscillation signal is transformed to the frequency measurement circuit composed of single chip microcomputer, and the single chip microcomputer can measure the frequency of the oscillator. When a large metal object such as a car passes by, the change of oscillation frequency is caused by the change of space medium. This change is used as the confirmation signal of the car passing through the ground induction coil. At the same time, the time interval between the beginning and end of this signal can be used to measure the moving speed of the car. The key technology is that the designed oscillator is stable and reliable, and the frequency changes obviously when a car passes by, which is not as accurate as the license plate recognition technology.

The license plate recognition system can be used not only in parking lots and other places, but also on roads. It can also identify stolen vehicles running on roads. With the increase of urban population, vehicles will inevitably increase, and the problems will also increase. Some of these problems can not be solved only by manpower, Therefore, automatic license plate recognition system is more and more widely used, which is closely related to the development of society and people's living needs.
