At present, the mainstream of China's parking system has replaced the Bluetooth card intelligent parking system with automatic license plate recognition. Regarding the advantages and disadvantages of these two parking lot management systems, let's talk about how they work separately. WELCOME to share your parking porject to us. www.coma-carparking.com
1. Bluetooth card system, only need to install a card reader at the entrance and exit, and then install the registered Bluetooth card in the car. After the vehicle enters the recognition range, the card reader recognizes the Bluetooth card and controls the barrier to open. Therefore, a car with a card can be identified as a car in the community. Open the door, and open the door if there is no card. Then if there are foreign vehicles or owner's cars without a card, it can only be solved manually.
Advantages: Internal car judgment is more accurate, and installation environment requirements are low.
Disadvantages: 1. The system has limited functions (only cars with Bluetooth cards are recognized, and the limitation is large); 2. The later cost is high (the car Bluetooth card for the user's large area, the number of each car will directly increase the cost, and it will be used for a long time There will be no electricity, failure, etc. need to be replaced); 3. Low security, it seems to identify the owner stably, in fact, the system that recognizes the card does not recognize the car, as long as the car with the card is placed in the same car, and the card can be easily removed and handed over . In addition, copying the Bluetooth card is now too easy. 4. Management and charging loopholes (vehicles without a registered card can only rely on humans, the system only knows the card and does not know the car. These factors can have too many crooked brains to move. For example, I use someone else ’s Bluetooth card to open the door for the car without the card. The parking fees for foreign cars can be embezzled, evaded, and released without permission.
Second, the license plate recognition system, the license plate recognition camera is installed at the entrance and exit, the car enters the shooting range of the camera, and the photo is triggered, and the recognition of the license plate number is used as the basis for judging release.
Disadvantages: The installation environment of the equipment has requirements. After all, the camera takes a fixed direction to take pictures. It needs to be fixed at an angle so that the front license plates of all vehicles passing here can be photographed. Recognition technology is not 100% means that there will be a time when the recognition is wrong. The equipment is more expensive, but there is no need to repeatedly buy a large number of cards, which is almost the same.
Advantages: 1. Management loopholes and charge loopholes of the card system can be basically solved, the license plate number is the vehicle's unique ID card. Passing cars must be paid. 2. Inner vehicles, different permissions, large operation setting space can extend many functions. After accessing the license plate system of the Ministry of Public Security, the license plates are easy to be caught and have higher security.
