2.SystemStructure Principle:
Wireless ultrasonic detector detects the parking space status, then transmit the detect information to
related wireless zone controller via RF signal. Meanwhile, wireless zone controller will collect these
information and forward to wireless router which connected to wireless central controller by Wifi. After
acquiring the whole garage parking information, the wireless central controller would send the updated
information to every LED screen in the car park by LED screen controller via wireless router. It realizes
the parking guidance function through above procedure
