Bluetooth Card Reading System and License Plate Recognition System, Their Advantages and Disadvantages

In the parking equipment market of Qingdao area, two kinds of equipment systems are mainly used: Bluetooth card reading system and license plate recognition system. The advantages and disadvantages of the two systems are as follows: Bluetooth system has basically been eliminated.

License plate recognition system. Vehicle license plate recognition camera is installed at the entrance and exit. The vehicle enters the camera shooting range and triggers the shooting. It can be divided into ground sense trigger, video trigger and virtual coil trigger. The license plate number is identified as the basis for judging release.
Disadvantages:
The installation environment of the equipment is required. After all, the camera takes pictures in a fixed direction. It needs a fixed angle so that all the front license plates of the vehicles passing through here can be photographed. Failure to identify means that there will be a time when the recognition is wrong. The equipment is more expensive.
But you don't have to buy a lot of cards over and over again. It's almost the same.
Advantage:
1. The management loopholes and charging loopholes of the card system can be basically solved. The license plate number is the vehicle's ID card. One of the cars that should be charged can't run, so it's hard for people to do things.
2. Internal vehicles, different permissions, operation settings can extend a lot of functions. After accessing the license plate system of the Ministry of Public Security, false licenses are easy to be caught, and the security is higher.

Advantage:
Internal car judgement is more accurate and installation environment requirements are low.
Disadvantages:
1. The function of the system is limited (only trucks are recognized, but the limitations are great).
2. The cost is high in the later period (the number of Bluetooth cards per car will directly increase the cost for the community with large users, and there will be no electricity, failure and other situations that need to be replaced after a long period of time);
3. Low security (seemingly stable identification of owners, in fact, the recognition card does not recognize the car system as long as there are cards whose car is the same, and the card can be easily removed and handed over. In addition, it's too easy to copy Bluetooth cards now. )
4. Management and fee loopholes (Vehicles without registration cards can only rely on manual work, and the system only knows that the cards do not know the car these factors can have too many skewed brains to move. For example, I use someone else's Bluetooth card to open the door to a car without a card, to evade the cost and let it go privately.

Generally speaking, Bluetooth card reading system has the advantage of accuracy, there are no errors in theory, but temporary vehicle registration is more troublesome for the community with more external vehicles or open parking spaces directly.
There is a risk of security misappropriating parking fees, and battery replacement is also a factor to be considered. And the advantage of the license plate recognition system is its universality, that is, no matter what car comes, it automatically registers the license plate and time information.
In the case of more external vehicles, it can greatly improve efficiency. However, the disadvantage lies in the higher requirements for the site, as far as possible to achieve the straight lane, and there may be some missed recognition and misrecognition. At present, the license plate recognition technology in Qingdao area has been very mature.
The rate of omission and misunderstanding is very low. With the rapid development of Intelligent Cloud platform, license plate recognition system is gradually becoming the mainstream of parking lot.
Bluetooth card system, only need to install a card reader at the entrance and exit, and then install a registered Bluetooth card on the car. After the vehicle enters the recognition range, the card reader recognizes the Bluetooth card and controls the opening of the gate. That is to say,
The car with a card can be identified as the car inside the community, open the door, no card will not open the door. Then if there are foreign vehicles or owner cars without card, they can only be solved manually. Author: Tuoying Technology Co., Ltd.
