[0098] Figure 2 It is a structural diagram of an underground garage car-finding device provided by one or more embodiments of the present invention.

[0099] like Figure 2The underground garage car search device shown includes: a map information module, a beacon setting module, and a path planning module;

[0100] Map information module, used to obtain map information of the underground garage;

[0101] The map information of the underground garage includes information on the geographic coordinate locations of the underground garage entrance and exit, information on the three-dimensional space inside the underground garage, and information on the geographic coordinates of a two-dimensional plane of the three-dimensional space inside the underground garage based on the information on the geographic coordinate locations of the underground garage entrance and exit;

[0104] It is worth noting that although this system only discloses a map information module, a beacon setting module, and a path planning module, it does not mean that this device is limited to the above-mentioned basic functional modules. Rather, what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the existing technology to form an infinite number of embodiments or technical solutions. In other words, this system is open rather than closed. Just because this embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned basic functional modules.

[0105] Figure 3 It is a schematic diagram of an underground garage according to a specific embodiment of the present invention.

[0106] In a specific embodiment, multiple simple devices with BLE functions are provided in the underground garage, and these devices are set to send BLE broadcasts regularly. The outer layer of the device is printed with a QR code of the BLE device MAC address, which can be obtained by scanning. According to the BLE device MAC address, it is only necessary to set the layout of the underground garage (such as Figure 3 In the hypothetical underground garage, areas A, B, and C are marked according to the directions of east, south, west, and north, and are located on different floors. The signal of each BLE device roughly covers one parking space. The MAC address corresponding to the BLE device obtained by scanning the code is marked on the map to complete the construction of the underground garage map.

[0107] A usage scenario: After the vehicle enters the underground garage, set the vehicle to park and start the BLE scanning function of the car computer to obtain the unique identification of the underground garage BLE broadcasting device (the BLE on the car computer can scan multiple different BLE broadcasting devices at the same time, and the broadcast distance of the BLE device is set to 5-7 meters, which is greater than the range of people's ability to observe the surrounding environment). The device with the strongest signal strength is selected as the device where the owner is located, and the MAC address of the garage BLE broadcasting device is recorded and sent to the owner app on the user's mobile phone. The owner can obtain the location of the vehicle, so that the owner can accurately find the parking area of ​​his vehicle and use Beidou navigation in the ground area to obtain the nearest entrance to the vehicle parking area. If the navigation position cannot be obtained when arriving underground, the owner can use the mobile phone to obtain the nearest garage BLE device, quickly locate the area where he is, and quickly find the way to the parking area according to the garage instructions.

[0108] like Figure 3 The garage layout diagram shown above is more complex in underground parking lots. Therefore, at least one BLE broadcast device is installed in each parking area. This allows the car computer to obtain the BLE MAC address and determine the specific area. Once the information is sent to the user's mobile phone, the phone can obtain the parking area's location and clearly identify the closest exit. If the parking lot is above ground, the nearest entrance can also be found. Once inside the underground parking lot, the BLE broadcast address can be obtained to quickly determine the user's location. The shortest route is displayed on the map. If the parking lot is multi-story, the user can be directed to the appropriate floor and the appropriate direction. BLE devices can be arranged in a matrix pattern in open areas of the underground garage, or in a chained fashion at entrances, within aisles, and at ramps.
