Main function of Parking LED light in PGS:


Controlled by the ultrasonic sensor, the main usage of the LED indicator is to show the current parking space status in real time. When the space is occupied, it shows red; And if there is no car in the vehicle, it turns green. Hence, after drivers entering to the carpark, they could find the avaiblable parking space quickly under the guidance of the LED indicator.


There are three colors for your choice, red, green and blue. Color blue is specially used for disables to guide them parking convinently.













2.Main Devices of PGS: 


 1.Ultrasonic Detector(UD)    (1 parking space=1 ultrasonic detector)


 2.LED Indicator            (1 parking space=1 LED indicator)


 3.Zone Control Unit(ZCU)    (1 ZCU=30~40 ultrasonic sensors,35 at best)


 4.Central Control Unit(CCU)  (1 CCU=60 ZCU)


 5.LED Panel               (number of LED panels are up to the real situation of carport)










System Structure:












network cable(CAT-5E):  connections among CCU,ZCU,led display,sensor-sensor


telephone line:  sensor-led indicator





Working Principle of PGS:




1. UD detects parking space status(occupied/free) by ultrasonic wave.If occupied ,UD will send command to LED indicator for showing RED,if free,LED indicator will turn Green.(LED indicator is connected with UD by telephone line and under UDS control)




2. Meanwhile, when parking space status changes, UD will send real-time changed message to ZCU. ZCU will receive and transfer the information to CCU.




3. CCU will receive and process the information from ZCU. After processing, data will be transmitted to LED display for showing available parking space currently via ZCU, thus helps guide drivers to empty parking spaces quickly.
