1 How Parking Guidance System/parking assist system works:
MAIN FUNCTION: guide the drivers to find the free lots quickly.
Firstly, UD takes use of ultrasonic wave to detect the parking space to see if it is occupied by vehicles and transfers relevant commands to LED indicator which will turn from green to RED, or it will keep GREEN. Meanwhile, UD transmit its status messaage to ZCU immediately. and ZCU will collect and transmit the information to CCU. CCU processes these data and sends the relevant commands to ZCU and LED panel.

2 KEYTOP parking guidance systems / parking assist system advantages:
1) The technique of ultrasonic detector is steadyand its anti-jamining capability is strong.
2) UD's accurate rate is higher than loop sensor which has problem of weak magnetic and repeated detection. The base plate of UD is zoom type to avoid the problem causing by different setting angles without error accumulation.
3) UD has two detection methods: one is to detect the ground, the other is to detect the vehicles.Both of the types are available for tall kinds of car park terrain.
4) The instruction's process chip and memory chip of UD has the function of storing different setting values. (keep address setting and self-adapting setting and etc.) So it is unnecessary to reset after power down.
