Wireless Ultrasonic should be installed right ahead of each parking space.It will collect information of parking space every three seconds, if parking status changes, transmit RF signal to zone controller at once,otherwise transmit every 5minutes.The working principal of wireless ultrasonic detector is ultrasonic reflection. The detector transmits RF signal, the ultrasonic receive circuit will receive the signal if reflected by barrier. After certain processing, the controller would identify the signal information. When the distance detected by detector less than ranging setting, it signify the parking space is occupied or the parking space is vacant.
Componets of the open space outdoor parking system: 1. Wireless Ultrasonic Detector 2. Wireless Zone Controller 3. Wireless Central Controller 4. LED Display Screen
This system collects real-time information of each parking space through wireless Magnetic detector which will be installed at each parking space. The zone controller receives and collects RF signal from each detector of its management area, then send back to central controller after data compression. The LED display will receive the carport information from central controller and dispaly the amount of the available lots currently in terms of number and word.
Advantages of using this system:
For driver: 1. Save time in finding an available parking space. 2. Save energy and oil fee.
For carpark owner: 1. Low cost, easy-operation and installation, maitainence. 2. Control the resl-time carpark parking space status. 3. Efficient carpark management keeps a good impression in consumer's mind.
For city: 1. Low-carbon, help protect the environment. 2. Reduce the rate of traffic jam with this parking guidance system.
