1. The main function of LED lamp in PGS(Parking Guidance System):
Controlled by the ultrasonic sensor, the main usage of the LED indicator is to show the current parking space status in real time. When the space is occupied, it shows red; And if there is no car in the vehicle, it turns green. Hence, after drivers entering to the carpark, they could find the avaiblable parking space quickly under the guidance of the LED indicator.
There are three colors for your choice, red, green and blue. Color blue is specially used for disables to guide them parking convinently.
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.
