1. The  Main Function of Parking Zone Control Unit:


The node controller(ZCU) is the middle layer of ultrasonic parking detector, which is to manage a group of ultrasonic detectors, detects then loops the information of the detectors and send the relevant information to central controller. One node controller can support 60 detectors in max.






2. How Parking Guidance System Works:


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