Main function of ultrasonic detector for parking lots:
Installed at the above of the middle of the parking space, parking ultrasonic detector takes use of its ultrasonic wave to detect the parking space status to see if the parking lot is occupied and sends command to parking indicator to turn RED when occupied, otherwise it will keep GREEN if free.Meanwhile ,it transfer the status message to ZCU for information collection.
Working principle of Parking Guidance System:
Firstly, ultrasonic detector takes uses of ultrasonic wave to detect the parking space to see if it is occupied and transfer the relative commands to LED indicator which will turn from gree to RED when occupied, or it will turn GREEN.
Meanwhile, the UD transmits its status message to ZCU immediately, and ZCU will collect and forward the information to CCU. CCU processes these data and sendsthe relevant commands to ZCU and LED panel.
