In the current parking system, two main systems are used: Bluetooth card reading system and the license plate recognition system. Now COMA introduce the advantages and disadvantages of these two systems:
For the Bluetooth card system, you only need to install a card reader at the entrance and exit, and then install the registered Bluetooth card on the car. After the vehicle enters the recognition range, the card reader recognizes the Bluetooth card and controls the gate to open. That is to say, if there is a card on the vehicle, it can be identified as a car. If there is no card, the door will not be opened. Then if there is an temporary vehicle or an owner's car that does not have a card, it only can be solved manually.
Advantage:
The internal vehicle is judged more accurately and easy to installation.
Disadvantages:
1. The system has limited functions (only vehicles with cards are recognized, and with large limitations );
2. The maintenance cost is high (the number of each car will directly increase the cost, and it will be out of power for a long time)
3. Management and charging issues (vehicles without a registration card only can rely on manual opening)
License plate recognition system.
The license plate recognition camera is installed at the entrance and exit, the car enters the camera shooting range, triggers the photographing, and recognizes the license plate number as the basis for judging the release.
Disadvantages: The equipment installation environment has requirements. After all, the camera is fixed in the direction of the camera. It needs to be fixed at an angle so that all the front license plates of the vehicles passing through here can be photographed. Less than 100% recognition technology means there is a time to identify mistakes.
Advantages: 1. Card system management and charging problems can be basically solved, the license plate number is the vehicle's unique ID card.
2. The vehicle has different permissions, and the operation settings can extend many functions.
In general, the advantage of the Bluetooth card reading system is accuracy, there is no error. But for more external vehicles, temporary vehicle registration is more troublesome. The advantage of the license plate recognition system is versatility, that is, automatic registration of license plates and time information is carried out no matter what car comes in and the efficiency can be greatly improved in the case of a large number of external vehicles. However, the disadvantage is that the site requirements are high, it is best to be achieve straight lanes and there may be some leak identification and misidentification. Coma can provide a complete and efficient management system for license plate recognition. www.coma-carparking.com
