1. Wireless Zone Controller(ZCU)
ZCU is responsible for collecting data of detectors and
transmits to CCU.
The quantity of detectors ZCU supports depends on the communication
distance between ZCU and detector.
The communication between ZCU and detector is wireless RF.Their
max. communication distance is *0m.(ZCU
as the centre).
2 How wireless Parking Guidance System/parking assist system
works:
Installed wireless magnetic detector at every parking space to get
parking information.The detector detects the
geomagnetic field change every 3 seconds to judge the vehicle
presence.If the parking status changes,it sends
wireless signal to the wireless ZCU immediately,otherwise,the
signal will only be transmitted every 5 minutes.The
wireless ZCU transmit the parking data to CCU after compressing
base on the certain rules.Finally,this data will be
transmitted to directional led display after the processing of
CCU.Meanwhile,the parking data will be sent to the sever
and stored in its database. The user can visit sever to learn
parking information including year/month/date statistic
data.
3 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.
