Main Functions of Ultrasonic Detector (ultrasonic sesnor)
1). UD(ultrasonic detector) as one of the main part of
car parking system, makes use of ultrasonic detecting the parking space to get message and transfer to ZCU or other equipments by RS485.
2). One parking space needs one UD which is installed in the middle of the car park space.
Firstly, UD takes use of ultrasonic wave detecting status of parking space to see if it is occupied by vehicles and transfer relevant commands to LED indicator which will turn from green to RED when it is occupied, or it will keep GREEN. Meanwhile, UD transmits its status message to ZCU immediately. and ZCU will collect and forward the information to CCU. CCU will process these data and send the relevant commands to ZCU and LED panel.
