The RFID tag is used for storing position number information and corresponds to corresponding positions in a digital map of the underground parking lot one by one; the navigation device installed on the parking space is used for prompting a user whether to reach a target parking space, and the RFID tags arranged in the parking space are used for storing the serial number information of the parking space and correspond to the corresponding parking spaces in the digital map of the underground parking lot one by one. For example, the number "1" is stored in the navigation device No. 1 located at the entrance, and when the vehicle passes through the position, the navigation device reads the information of the number "1", and updates the vehicle position information on the digital map received by the vehicle, thereby realizing the positioning function.
When a vehicle to enter an underground parking lot reaches an entrance position of the underground parking lot, a card reader arranged at the entrance position acquires vehicle information of the vehicle and transmits the vehicle information to a processing device; wherein the vehicle information includes: the length, width and number plate number of the vehicle, and the processing device can be a computer.
After the processing device receives the vehicle information, according to the length and the width of the vehicle, a target parking space with a proper size is allocated to the vehicle in the remaining parking spaces displayed by the digital map in the processing device, and according to the current position of the vehicle and the position of the target parking space, an entrance navigation route is planned, for example, the target parking space is allocated as a parking space 14, so that the entrance navigation route can be planned to be 1 → 2 → 12 → 13 → 14 → 15 → 28 → 29, and then the digital map is transmitted to the vehicle through wireless transmission so as to be displayed on a display instrument of the vehicle, and the vehicle can also acquire and store the digital map in advance through other modes, for example, downloading from the internet; wherein, the target parking space and the driving navigation route are marked in the digital map.
After receiving the digital map, the vehicle can drive to a target parking space according to the driving navigation route marked in the digital map; in the process, the number information embedded in the positioning device under the ground surface of the driving channel is read through the card reader arranged on the vehicle, and the number information is transmitted to the display instrument of the vehicle to display the position number information of the positioning device, which can be displayed in the vehicle display instrument, of the vehicle owner in a digital map so as to know the specific position in the underground parking lot, so that whether the vehicle runs according to the driving navigation route or not can be judged, and the vehicle can quickly reach the target parking space.
After the vehicle reaches the target parking space, the card reader on the vehicle reads the parking space number information embedded in the positioning device under the ground surface of the target parking space, and the parking space number information is transmitted to the display instrument of the vehicle to be displayed in the digital map, so that the vehicle owner can judge whether the vehicle reaches the target parking space.
Similarly, when the car owner wishes to exit the underground parking lot through navigation, the car owner can also drive out the underground parking lot in the above manner, and the details are not repeated here.
In summary, the structure and the implementation of the present invention are described herein by using specific examples, and the above description of the examples is only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention, and the scope of the present invention should be subject to the appended claims.
