[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and 2, fig. 1 is a block diagram of a car searching system according to the present invention, and fig. 2 is a flowchart of a car searching method according to the present invention.
A car searching system comprises a positioning navigation subsystem and a parking space management subsystem.
The parking space management subsystem comprises a vehicle identification unit and a parking space allocation unit which are in communication connection, the vehicle identification unit is arranged at an entrance and an exit of the parking lot, and the parking space allocation unit is used for allocating exclusive parking spaces for vehicles.
The positioning navigation subsystem comprises a position sensing unit and a navigation server which are in communication connection, the position sensing unit is used for sensing the real-time position of the vehicle, the navigation server is in communication connection with the parking space allocation unit, and the navigation server is used for navigating the vehicle according to the real-time position and the exclusive parking space.
When the vehicle searching system is used, the vehicle is firstly identified by the vehicle identification unit, then the parking space is allocated to the vehicle by the parking space allocation unit, and after the vehicle enters a parking lot, the real-time position of the vehicle is sensed by the position sensing unit, so that the navigation server navigates the vehicle. In general, vehicle positioning depends on navigation systems such as a GPS (global positioning system) or a Beidou, but in a parking lot, particularly an underground parking lot, signals of the navigation systems are poor, and the positions of parking spaces are relatively accurate, so that the data of the navigation systems are difficult to directly adopt for navigation.
Furthermore, the position sensing unit comprises a plurality of vehicle sensors fixedly arranged in the parking lot, the coverage areas of any two adjacent vehicle sensors are mutually overlapped, and the overlapping area is larger than the cross sectional area of the vehicle.
In a parking lot, a moving route of a vehicle is usually planned to avoid congestion, so that the vehicle can move along a fixed route after entering the parking lot, a vehicle sensor can also be arranged along the moving route of the vehicle, and the position of the vehicle is difficult to accurately control only by depending on a sensing result of the vehicle sensor because the range of the vehicle sensor is large. In order to ensure that the vehicle can be perceived when moving to the overlap area, the overlap area needs to be larger than the cross-sectional area of the vehicle, and in practical cases, the cross-sectional area of the vehicle is not fixed, but the area of the parking space is usually fixed, so the area of the overlap area can be determined according to the area of the parking space.
Further, the vehicle sensor is set to be a wireless communication fixed node, and the wireless communication fixed node is in wireless communication connection with a mobile terminal held by the vehicle host. The wireless communication connection mode can adopt a Bluetooth connection.
Based on the vehicle searching system, the invention also provides a vehicle searching method of the vehicle searching system, which comprises S1-S9.
And S1, deploying and initializing the vehicle searching system.
S2, the parking space distribution unit divides the parking lot into a plurality of parking areas, and each parking area is divided into a plurality of parking spaces.
And S3, when the vehicle arrives at the entrance and exit of the parking lot, the vehicle identification unit identifies the vehicle and acquires the license plate number of the vehicle.
S4, the parking space allocation unit acquires the license plate number from the vehicle identification unit, allocates one of the parking spaces as an exclusive parking space for the vehicle according to the license plate number, and sends the license plate number and the exclusive parking space to the navigation server.
And S5, the navigation server plans a navigation path according to the license plate number and the exclusive parking space.
S6, the position sensing unit acquires the real-time position of the vehicle and transmits the real-time position to the navigation server.
And S7, the navigation server generates a navigation prompt message according to the real-time position and the navigation path.
And S8, the navigation server sends the navigation prompt message to the position sensing unit.
And S9, the position sensing unit sends the navigation prompt message to the vehicle.
Further, specific methods of S1 are S1.1 to S1.2.
S1.1, selecting the positions of the vehicle sensors to enable the coverage areas of any two adjacent vehicle sensors to be mutually overlapped, and enabling the overlapping area to be larger than the cross sectional area of the vehicle. As described above, all the vehicle sensors are distributed along the moving route in the parking lot, and the area of the overlapping area is larger than the area of the parking space.
S1.2, installing a vehicle sensor, a vehicle identification unit, a parking space allocation unit and a navigation server.
Further, specific methods of S2 are S2.1 to S2.4.
S2.1, dividing the parking lot into a plurality of original areas and arranging the original areas in sequence.
And S2.2, dividing each original area into a plurality of sub-areas.
And S2.3, moving at least one sub-region to the next original region according to the reverse order so as to change the area of the original region to obtain a new region.
And S2.4, taking the new area as a parking area.
In S2.1, an average division method may be adopted during division, that is, the areas of each original region are equal, which is simpler, but the sizes of the original regions are not regular many times, which is not beneficial to practical use, and is inconvenient in the navigation process, so that the original regions need to be adjusted to obtain a better parking region. After optimization, all parking areas are different.
In S4, the specific method of allocating exclusive parking spaces is S4.1 to S4.2.
S4.1, according to the sequence of the parking areas, allocating a first vehicle to the first parking area, allocating a second vehicle to the second parking area, and the like.
And S4.2, repeating S4.1, and stopping distributing the vehicles to any parking area after the parking area is full.
In the prior art, a mode of intensively allocating to one parking area firstly and allocating to the next parking area after one parking area is full is mostly adopted, so that local congestion is caused, and in the case of commercial places, misunderstandings that few customers exist and scenes are cool and clear are caused. Since the parking areas are optimized when being divided, the smallest parking area is full first, but the parking area has the smallest area, so that congestion does not occur.
Further, specific methods of S6 are S6.1 to S6.3.
S6.1, in the moving process of the vehicle, the mobile terminal is in communication connection with the wireless communication fixed node.
S6.2, when the vehicle is in the overlapping part of the coverage areas of two adjacent wireless communication fixed nodes, determining the real-time position, and identifying the real-time position by using the two wireless communication fixed nodes.
And S6.3, a wireless communication fixed node which establishes wireless communication connection with the vehicle sends the real-time position to the navigation server.
Since the overlapping area between two wireless communication fixed nodes is unique, the real-time position can be directly identified by the two wireless communication nodes, and the identification format can be 'wireless communication fixed node connected in advance, wireless communication fixed node connected in the later'.
Further, specific methods of S7 are S7.1 to S7.4.
S7.1, the navigation server divides the navigation path into a plurality of vectors which are connected end to end.
S7.2, the navigation server corrects one vector according to the real-time position.
And S7.3, the navigation server generates a navigation prompt message according to the vector.
S7.4, repeatedly executing S7.2 to S7.3.
In the moving process of the vehicle, the position of the vehicle is constantly changed, so that the navigation prompt message is also changed in real time, and particularly, the moving distance in the navigation prompt message needs to be constantly changed, so that the vector needs to be corrected.
Further, in S7.2, the vector is corrected when the distance between two real-time positions exceeds a threshold or the vector of the real-time position map changes.
Because the length of the vector is different, for a shorter vector, the navigation prompt message may not be adjusted during the vehicle moving process, and for a longer vector, the time for the real-time position to be mapped on the vector is longer, so that the vehicle needs to be continuously corrected to ensure that the vehicle can move along the correct navigation route.
The process is the process when the vehicle enters the parking lot, and the method positions the mobile terminal of the vehicle owner, so that the specific process of the vehicle owner in taking the vehicle is the same, and is not repeated.
In this embodiment, the vehicle identification unit can adopt prior art, and no longer give unnecessary details, and the parking stall allocation unit can adopt low-power consumption high performance chips such as STM32, and navigation server can adopt the computer.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
