1. MainFunctions of Ultrasonic Detector/ Intelligent CarParking Guidance System/ Parking Equipment

1). UD(ultrasonic detector/ultrasonic sensor) as one of the main part of parking guidancesystem (parking space detection) makes use of ultrasonicdetecting the parking space to get message and transfer to ZCU orother equipments by RS485.
2). One parking space needs one UD which is installed in the middleof the car park space.

2.HowParking Guidance System (parking spacedetection) Works:

 
Firstly, UD takes use of ultrasonic waveto detect the car space to see if it is occupied by vehicles andtransfer relative command to LED Indicator which will turn fromgreen to RED when occupied, or it will keep GREEN;meanwhile, the UD transmit its statusmessage to ZCU immediately, and ZCU will collect and forward theinformation to CCU; CCU processes these data and sends the relevantcommand to ZCU and LED panel.
