parking guidance (Zone Controller)

الوصف

 1 Zone Control Unit of parking guidance :

1) The LCD in ZCU is to show the detector's working status.

2) Main Functions:

It is to inquire about the relevant sensor status via RS***-B by turns and forward the data by RS****-C. Meanwhile, ZCU forwards the commands of CCU to LED SCREEN via RS****-B. 

2.How parking guidance system (car park 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.
