[0033] The parking space detector is used to detect the parking state information of each parking space in the underground parking garage. In this embodiment, each parking space in the underground parking garage includes a non-predetermined parking space and a predetermined parking space.

[0034] A high-precision, low-power parking space detector device based on the NB-iot network is installed in the middle of the non-reserved parking space, and a parking space lock based on the 25NB-iot network is installed in the reserved parking space. The parking space lock uses an intelligent ground lock with a built-in 5G chip, which is wirelessly connected to the positioning navigation and parking management platform 1 and is powered by a rechargeable lithium battery. It is directly glued or fixed to the ground of the parking space with screws.

[0035] The parking space detector for non-reserved parking spaces uses ultrasonic and geomagnetic sensing devices 6 to sense whether the parking space is occupied, and provides real-time feedback to the positioning navigation and parking management platform 1 and the terminal device 7 (including the owner APP), and sets an LCD guide screen with 2 to 4 columns on each side as a unit to display the parking space occupancy information.

[0036] The reserved parking space adopts an intelligent ground lock to lock the parking space. When the parking space is reserved by the car owner, the lock automatically rises and is lowered by the mobile phone APP end (i.e., terminal device 7) when the car owner needs to drive in.

[0037] The positioning navigation and parking management platform 1 is used to receive parking status information of each parking space.

[0038] In this embodiment, the positioning navigation and parking management platform 1 is composed of a computing control unit with computing and analyzing functions.

[0039] The display screen 2 is used to receive and display the parking space remaining information sent by the positioning navigation and parking management platform 1.

[0040] In this embodiment, the display screen 2 is an LCD guide screen, which includes a primary LCD guide screen and a secondary LCD guide screen. The primary LCD guide screen is used to display the number of remaining parking spaces on each floor, and the secondary LCD guide screen is used to display the number of remaining parking spaces in each direction. In this way, the car owner can understand the specific conditions of the parking space in a timely and clear manner for subsequent parking operations.

[0041] The radio frequency positioning base station 3 is used to obtain the positioning information of the vehicle to be parked and send the positioning information of the vehicle to be parked to the positioning navigation and parking management platform 1. The positioning navigation and parking management platform 1 is also used to send parking navigation information for the vehicle to be parked to the target parking space to the terminal device 7 according to the positioning information of the vehicle to be parked and the target parking space selected by the vehicle owner on the terminal device 7. In this way, the vehicle to be parked can move to the target parking space according to the parking navigation information to perform parking operations.

[0042] In this embodiment, specifically, a plurality of radio frequency positioning base stations 3 are installed at the entrance and exit of the underground parking garage and the structural top plate of the driving passage through which the vehicle passes. And the plurality of radio frequency positioning base stations 3 are arranged in sequence according to a predetermined spacing along the driving path direction. In this way, the positioning of the parked vehicle can be realized in real time to avoid the loss of the vehicle position.

[0043] The audio positioning base station 4 is used to obtain the positioning information of the car owner holding the terminal device 7 and send the positioning information of the car owner to the positioning navigation and parking management platform 1. The positioning navigation and parking management platform 1 is also used to send the car search navigation information of the car owner moving to the parking space corresponding to the parked vehicle to the terminal device 7 based on the car owner's positioning information and the parking space information corresponding to the parked vehicle, so as to facilitate the car owner to find the car in reverse.

[0044] In this embodiment, specifically, a plurality of audio positioning base stations 4 are installed on the structural top plate of the driving passage. Figure 2 , several audio positioning base stations 4 are arranged in a mesh shape. In this way, the car owner can find the parked car according to the car navigation information to complete the car search operation. In this way, full coverage of the positioning of the car owner holding the terminal device 7 can be achieved to avoid the positioning navigation and parking management platform 1 failing to obtain the location of the terminal device 7.

[0045] In this embodiment, the parking lock 5 installed in the parking space can also open or close the locking state of the parking space according to the positioning navigation and the car locking information sent by the parking management platform 1.

[0046] Specifically, the positioning navigation and parking management platform 1 is connected to the parking lock 5, the parking detector, the radio frequency positioning base station 3, the audio positioning base station 4 and the display screen 2 respectively through the wireless local area network. The radio frequency positioning base station 3 and the audio positioning base station 4 are used to accurately locate vehicles and personnel; the parking lock 5 is used to realize the parking management and parking reservation functions; the parking detector is used to realize the accurate monitoring of the status of each parking space, and send the information to the positioning navigation and parking management platform 1 through the network according to the predetermined rules. After the positioning navigation and parking management platform 1 analyzes and processes, the parking space remaining information is published on the LCD guide screen to provide the owner with induced parking service. The owner queries the vehicle information and locates the vehicle position through the mobile phone. The positioning navigation and parking management platform plans and displays the optimal vehicle search path between the owner and the vehicle to assist the owner in finding the vehicle.

[0047] It should be understood that in this embodiment, the radio frequency positioning base station 3 uses the Bluetooth signal of the mobile phone to provide location services. It is arranged at intervals of 20 to 40 meters in the direction of travel on the top plate of the middle structure of a channel no larger than three lanes in the underground garage entrance and exit passed by the vehicle or in the connected underground road. The speed limit of the channel is 60 km / h. The base station has no communication requirements. Accurate positioning is achieved through calculation by the mobile phone APP and fed back to the navigation APP. The navigation following delay is less than 1 second.

[0048] The audio positioning base station 4 uses a sound wave broadcasting base station installed indoors to transmit ultrasonic signals, which are received by the mobile phone and accurately calculate the location of the car owner, so as to accurately locate and navigate the car owner holding the mobile phone.

[0049] Install audio transmission base stations on the roof of the underground garage, arranged at intervals of 40 to 50 meters. Figure 2 Schematic diagram of the layout of the audio positioning base station)

[0050] Both the radio frequency positioning base station 3 and the audio positioning base station 4 are designed based on the NB-iot network. When used in combination, they can ensure that vehicles and pedestrians can be accurately positioned in underground parking lots and indoor spaces where GPS / Beidou signals cannot be tracked, thereby achieving seamless indoor-outdoor and above-ground-underground positioning.

[0051] The following is a flowchart to illustrate the embodiment of the present application:

Figure 3 In a parking lot where radio frequency positioning base stations and audio positioning base stations have been installed, car owners can turn on the Bluetooth of their mobile phones, open the navigation app, search for available parking spaces, drive to the entrance of the underground parking lot, and view the number of remaining parking spaces on each floor through the first-level LCD guide screen. Car owners drive the vehicle to the floor with available spaces and view the number of remaining parking spaces in each direction through the second-level LCD guide screen. Car owners drive the vehicle to the direction of available parking spaces and view specific parking space information through the mobile phone APP. The parking space search process supports real-time positioning and displays the owner's position in the parking lot in real time. When the owner deviates, the optimal car search route is automatically replanned to guide the owner to find a parking space quickly.

[0053] Figure 4 The flowchart for finding a car by Bluetooth and audio positioning. Figure 4 The process of finding a car by Bluetooth and audio positioning is the process of finding a car by radio frequency positioning and audio positioning. In parking lots where radio frequency positioning base stations and audio positioning base stations have been installed, car owners can use the Bluetooth navigation function to find a car. Car owners use WeChat on their mobile phones to scan the QR code pasted in the parking lot, or open the car search interface in the WeChat public account, and then enter query conditions such as license plate or parking space number to query the location of the vehicle. The system automatically plans the optimal route to find the car and guides the car owner to find the car. The process of finding a car supports real-time positioning, and displays the location of the car owner in the parking lot in real time; when the car owner deviates, the optimal route to find the car is automatically replanned to guide the car owner to find the vehicle quickly.
