7. The working method according to claim 1, wherein in the step (1), the captured picture is recognized, the license plate information of the vehicle is extracted, the related information of the license plate number is retrieved from the database, if the vehicle is a fixed vehicle, the validity period of the parking space corresponding to the vehicle is continuously checked, the barrier is opened in the validity period, the indicator light module of the road ultrasonic detector at the entrance to the parking space path is opened, and if the vehicle is not in the validity period, the system regards the vehicle as a temporary vehicle; if the temporary vehicle is detected, the system allocates an optimal parking space for the vehicle, at the moment, the management server stores parking space information, license plate information and driving-in time into the database in a one-to-one correspondence mode, then the barrier is opened, and the driving-in time of the vehicle is recorded as initial time.
8. The working method of claim 1, wherein whether the first section of the path actually traveled by the vehicle is consistent with the first section of the optimal path planned by the system is compared, if the path traveled by the vehicle is inconsistent with the planned path, a new path is planned based on the real-time position of the vehicle, a switch command is issued to the corresponding road ultrasonic detector, an indicator light module of the road ultrasonic detector of the new path is turned on, the road ultrasonic detector of the original path is turned off, and the effect of real-time light navigation is achieved; and if the running path is consistent with the planned path, the switching command is not executed.
