The true long-distance parking should have the following characteristics:
First, directionality
(The read angle of the Bluetooth reading head 180° is good for directional reading, there is no front and rear lane interference problem)
(The microwave is 360 degrees without direction, and it is half angled with the iron plate. There will be a case where the vehicle enters the yard and goes out of the yard.)
Second, a card and a car, readers anti-collision. Will not read multiple cards in the same way as a car in a parking lot (if the E car and the F car come in at the same time, the microwave group reads the card to the F car, but the picture captures the E car, then we park The image contrast does not make sense.)
(If the E car and the F car come in at the same time and the microwave reads the card at the same time, what should I do?)
(Microwaves are generally 5-8 meters, installed in front of the control machine. When the E car is in front of the F car followed by the exit field, the E car reads the card out of the parking lot, the barrier gate is closed but the F car has reached the pole before it is Can't read the card before I can walk.)
Third, do not have to drive the window to read the card
(The microwave's card can not be read in the car within 3-8 meters, so it is still necessary to read the card in the parking window. Some people may say that we can read the head and can read 80 meters. There is no sense to increase the power to the environment. Pollution)
Fourth, from the mobile phone frequency, the same frequency wireless, the impact of the weather environment.
(If the vehicle is on the phone while in the parking lot, the microwave card will burn the card, and the distance for reading the card will be greatly reduced. Bluetooth reading is a combination of Bluetooth communication and CDME technology, which is not affected by the same frequency.)
Fifth, the encryption of data communications and the safety of parking lots.
(Many people now use something like a wireless dial switch. He doesn't have an ID number just to give the controller a signal to open the gate. The parking software doesn't have data to enter or leave the yard. The wireless dial switch has no encryption for communication. Easy to crack, there is no safety in the parking lot.)
The advantages and disadvantages of the difference between microwave and Bluetooth for parking
The advantages and disadvantages of the difference between microwave and Bluetooth for parking lots are now divided into Bluetooth and microwave, but many customers do not understand the essence of these two technologies.
