1、 Reminder for purchasing Bluetooth card readers:
At present, some manufacturers' Bluetooth card readers on the market often experience insensitive sensing distance after application, which is common There are several situations, and it is recommended that customers choose to use them carefully.
1Close sensing distance: the same2Placing the cards in the same car results in varying sensing distances, and The sensing distance varies greatly; (Except for cars with protective film and general situations like this)
2Poor penetration effect: Even a piece of white paper placed between the card and the card reader cannot penetrate.
3Low waterproof performance: prone to water ingress on rainy days, leading to corrosion and poor contact of the circuit board.
4Lack of stability: When no one swipes the card or when encountering strong sunlight, the barrier gate opens inexplicably.

2、 Advantages of Zhonganda Bluetooth Parking Lot System:
1Card swiping without stopping throughout the entire process: No parking,Without opening the window to read cards, car owners are no longer affected by the wind, rain, and snow outside the car window in adverse weather conditions. Greatly increase the traffic volume and eliminate the phenomenon of long queues during peak traffic periods.
（10－60Kilometer speed, induction3-25Rice);

2Comprehensive card reading technology: Bluetooth signal has strong penetration and is not affected by the environment. The card can be placed in the car Hanging inside and outside on the windshield; （2.4GIt can be placed in any position
3Fully automatic error correction mechanism: Multiple devices can read cards simultaneously or multiple cards simultaneously without interfering with each other, ensuring accuracy Ensure that the entrance and exit gates do not have incorrect opening phenomena;
4Directional adjustment function: The card reader can adjust the directionality, solving the problem of parking lots The problem of adjacent lane interference in the vehicle management system.
5Client encryption function, customers can set it freely according to their own needs6Password with digits for security Protecting not only ensures the safety of users but also safeguards the interests of businesses.
6Fully seamless integration link: with existing onesIC／IDCard system compatibility, seamless docking (improved)show If the existing parking lot is close rangeICorIDThe parking lot system aims to achieve remote card swiping for entering and exiting parking Generally, only a Bluetooth card reader and Bluetooth card need to be added to the field. Seamless compatibility with the original system, The original system can still be used as usual. ）

4、 Answers to questions during use:
Two cars enter the parking lot entrance or exit at the same time. The car in front does not have a card, while the car behind has a card. The system will release the car in front?
Answer: In the application of parking lot management system, if a remote card reading system with no direction or weak directionality is used, in this case, the system will automatically read the card and release the car in front without a card, while the one with a card will be released The car cannot enter the parking lot. If we use our company's remote card reading system, we can completely handle this situation To avoid releasing vehicles without cards; The remote card reader produced by our company is specifically designed for parking lots orETCshould Using a designed remote card reading system that utilizes infrared positioning and RF transmission synchronous communication technology Infrared is used to adjust the card reading distance and range, ensuring that the card reading range only covers the preceding vehicle and cannot be read by the second vehicle.
