When a car into the parking lot every crossroads, will automatically be triggered vehicle guide manager and to central controller sends a signal, the central controller according to the current situation that the use of the parking lot puting the optimal empty position, and feedback driving route to vehicle guide manager, through the LED screen display indicating arrow lead vehicle, greatly improving the parking lot parking utilization rate, reduce the management cost。 When vehicles or berth docking with the driving position, parking release manager will update LED screen on the residual parking number information. At the same time, this system for other senior parking lot integrated management system integration and extension provides convenient function interface, has the very good open.
