Comparison of Advantages and Disadvantages between License Plate Recognition System and Bluetooth Card Read System
Comparison of Advantages and Disadvantages between License Plate Recognition System and Bluetooth Card Read System
In the current parking equipment market, two main equipment systems are used: Bluetooth card reading system and license plate recognition system. Now we introduce the advantages and disadvantages of these two systems:
(1) 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. The equipment is more expensive, but you don't have to buy a lot of cards repeatedly, it's almost the same.
Advantages: 1. The card system management loopholes and charging loopholes can basically be solved, and the license plate number is the proof of the vehicle. The one that collects the money can't run, and it's hard for people underneath to do things.
2. Intrinsic vehicles, different permissions, and large operational settings can extend many functions.
(2) Bluetooth card system
Just 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 car, it can be identified as a car inside the cell. If the card is opened, if there is no card, the door will not be opened. Then if there is an outside vehicle or an owner's car that does not have a card, it can only be solved manually.
advantage:
The internal vehicle is judged more accurately and the installation environment is low.
Disadvantages:
1. The system has limited functions (only trucks are recognized, and the limitations are large);
2. The high cost in the later stage (the car Bluetooth card for the user's large cell, the number of each car will directly increase the cost, and the use of a long time will be no power, failure, etc. need to be replaced);
3. Low security (it seems to be a stable identification of the owner. In fact, the system that recognizes the card does not recognize the car, as long as there is a card, the car is the same, and the card can be easily removed. In addition, it is too easy to copy the Bluetooth card now.)
4. Management and charging loopholes (vehicles without registration cards can only rely on labor. The system only knows that the card does not know the car. These factors can have too many brains to move. For example, use someone else's Bluetooth card to open the door to a car without a card, and evade Fee, private release)
In general, the advantage of the Bluetooth card reader system is accuracy. There is no theoretical error. However, for a community with more external vehicles or directly opening the parking space, temporary vehicle registration is more troublesome. The risk of fees, battery replacement is also a factor to consider. 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 requirements for the site are high, and the lane can be straight. In addition, there may be some leak recognition and misidentification. At present, the license plate recognition technology is very mature, and the rate of missed recognition and misrecognition is extremely low. With the rapid development of intelligent cloud platforms, license plate recognition systems are gradually becoming the mainstream of parking lots.
