Install right above every parking space,collect the real-time parking space information  through the principle of ultrasonic measuring the distance. 

Then transmit feedback of collecting information to led indicator and node controllers through RS-485.

1. Main Functions of Ultrasonic Detector (parking sensor)

1). UD(ultrasonic detector) as one of the main part of car parking system (car lift ) 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.

 

 

 

 

2 how parking system works:

Firstly, UD takes use of ultrasonic wave to detect the car space to see if it is occupied by vehicles and transfer ralative commands to LED indicator, which will turn from green to RED, or it will keep GREEN. Meanwhile, UD transmit its status message to ZCU immediately and ZCU will collect and transfer the information to CCU, CCU processes these data and send relevant commands to ZCU and LED panel.
