[0002] Battery swap stations are facilities that provide battery replacement services for new energy electric vehicles. The advantages of battery swap stations are high efficiency, convenience, centralized management, and extended battery life. The time it takes for a new energy vehicle to be replaced at a battery swap station is basically less than 2 minutes. For new energy vehicle owners, the time it takes to go to a battery swap station to replace batteries is mainly the waiting time.

[0003] There can be multiple sub-stations in a battery swap station. The actual queuing scenarios in the existing multi-station scenarios are varied. For example, all sub-stations in multiple stations use the same queue team, all sub-stations in multiple stations use different queue teams, and the queue teams of sub-stations in multiple stations partially overlap, resulting in inaccurate queuing vehicle information at each sub-station in the battery swap station, which increases the queuing time.

[0004] Therefore, there is an urgent need for a method for obtaining queuing vehicle information, a terminal device and a readable storage medium to solve the above problems. Summary of the invention

[0022] In order to further explain the technical means and effects taken by the present invention to achieve the predetermined invention purpose, the embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present invention. Through the description of the specific implementation methods, the technical means and effects taken by the present invention to achieve the predetermined purpose can be more deeply and specifically understood, and the attached drawings are only for reference and explanation purposes, and are not used to limit the present invention.

[0023] See also Figure 1 , Figure 1 The figure is a flow chart of a method for acquiring queuing vehicle information according to the present invention.

[0024] like Figure 1 As shown, a method for obtaining queuing vehicle information provided by an embodiment of the present invention includes the following steps: S11: Acquire multiple first geographical location ranges and a second geographical location range of all vehicles within a preset range of the battery swap station, wherein each of the first geographical location ranges corresponds to at least one substation in the battery swap station.

[0025] Multiple substations in a battery swap station can be multiple battery swap stations at the same location, or multiple substations (or battery swap areas) in one battery swap station for vehicles to swap batteries. Multiple battery swap stations are located at the same location (i.e., multi-station battery swap stations, where each actual battery swap station in multiple stations is a substation). Both operating vehicles and personal vehicles in hot spots in the city (such as highway service areas, railway stations, airports, key business districts, etc.) have the need to swap batteries and replenish energy. The maximum number of batteries that a standardized battery swap station can accommodate is limited, and it cannot accommodate traffic that exceeds its maximum battery swap frequency. Therefore, multiple battery swap stations will be built continuously at the same location (such as the same parking lot) to provide services for new energy vehicles, to avoid long-term operation of the battery swap station at non-maximum load.

[0026] The first geographic location range may be all GeoHash values ​​in the pre-set area to which each substation belongs, and each substation contains multiple GeoHash values ​​in the area. For example, the area with a radius of 10 meters of substation A is divided into the parking area of ​​substation A, and the area with a radius of 10 meters of substation B is divided into the parking area of ​​substation B. Then, the GeoHash value in the parking area is obtained, and it is associated and bound with the corresponding substation A or B, and saved.

[0027] The first geographical location range can also be the GeoHash value within the electronic fence area set in the camera device corresponding to the substation. For example, the operator maintains the queuing electronic fence of each substation of the battery swap station in the battery swap station information. Calculate all GeoHash values ​​in the electronic fence corresponding to each substation. If the battery swap station is a multi-station battery swap station, all its substation GeoHash are traversed in units of multiple stations, and the substation corresponding to each GeoHash is calculated. Then save the substation and the corresponding GeoHash. Because the frequency of changes to the electronic fence of the battery swap station is very low, after saving, it can be directly called when calculating the number of queuing vehicles at each substation in the subsequent steps, so as to quickly confirm the substation list corresponding to the vehicle. There can be only one substation or multiple substations in the substation list.

[0028] It should be noted that each substation corresponds to multiple first geographical location ranges, and the first geographical location range may also correspond to multiple substations.

[0029] Specifically, GeoHash is an algorithm that converts two-dimensional longitude and latitude information into a bunch of strings. By using Geohash as a unified unit for longitude and latitude comparison, a GeoHash represents a rectangle of different ranges at different lengths / precisions. The GeoHash with a precision of 9 used in this embodiment is approximately a rectangle with a side length of 2 meters. Its accuracy can be adjusted according to the needs of specific scenarios. When matching with the GeoHash of the vehicle, as long as the overlapping part of the two exceeds a threshold (such as 50%), the two are confirmed to match. It can be understood that the geographical location range is not limited to being represented by GeoHash, and GPS positioning and regional location marking can also be used.

[0030] The preset range of the battery swap station (its shape is not limited) can be pre-defined by the user or automatically set by the system. For example, the second geographic location range (such as GeoHash) of all vehicles within 250 meters of the battery swap station (a center point can be set at the battery swap station, with the center point as the center of the circle, or each substation can be used as the center point) is obtained. In other embodiments, the user can also pre-set the area and then obtain the second geographic location range of all vehicles in the area (such as a 100-meter long and wide area in front of the battery swap station, or a triangular area, or an irregular area, etc.). In this embodiment, the second geographic location range of the vehicle also uses the GeoHash value, that is, the area where the vehicle is located.

[0031] It should be noted that the first geographical location range and the second geographical location range need to be obtained regularly to adjust the queue vehicle information of each substation in real time according to the position change of the vehicle, for example, every 10 seconds, 30 seconds or 1 minute.

[0032] Optionally, the step of obtaining multiple first geographical location ranges includes: obtaining a queuing electronic fence corresponding to each substation in the battery swap station; obtaining multiple first geographical location ranges in the queuing electronic fence; and confirming the substation corresponding to each first geographical location range based on the queuing electronic fence corresponding to each substation and the multiple first geographical location ranges.

[0033] The queuing electronic fence is the fence of the battery swapping queuing area selected by the substation. It should be noted that the substation may not set up a queuing electronic fence.

[0034] Exemplarily, the queueing electronic fences set for each substation in the battery swap station are obtained in advance, and then the first geographical location range in each queueing electronic fence is obtained. For example, first obtain multiple GeoHash values ​​in the queueing electronic fence of substation a in the battery swap station, and then obtain multiple GeoHash values ​​in the queueing electronic fence of substation b, until the GeoHash values ​​in the queueing electronic fences of all substations are obtained. If the substation does not have a queueing electronic fence set, it cannot be obtained. After the GeoHash values ​​are obtained, each GeoHash value is associated with the substation according to the queueing electronic fence.

[0035] It should be noted that the areas selected by the queuing electronic fences of each substation may overlap. According to the queuing electronic fences corresponding to each substation and the GeoHash values ​​corresponding to each queuing electronic fence, one or more substations corresponding to each GeoHash value can be identified, thereby associating the GeoHash value with the substation.

[0036] S12: Match the second geographical location range with a plurality of first geographical location ranges corresponding to each substation respectively, so as to obtain the queue vehicle information of each substation.

[0037] By matching the second geographic location range with the first geographic location range, all vehicles within the preset range of the battery swap station can be identified to distinguish between queued vehicles and non-queued vehicles (vehicles that need battery swapping and vehicles that do not need battery swapping), and then further confirm the queued vehicles matched by each substation.

[0038] After confirming that a certain vehicle belongs to the queued vehicle, the vehicle can be placed in the queue of the corresponding substation in the battery swap station according to its matching first geographical location range, and then the queued vehicle information of each substation is obtained.

[0039] In another embodiment, before placing the vehicle into the queue of the corresponding substation, the queue vehicle information of each substation may be obtained first, and then the queue of the substation to be placed is determined according to the queue vehicle information. In this case, if the vehicle corresponds to multiple substations, when the queue vehicle information is subsequently updated, the vehicle does not need to be deleted from the queues of other substations except the target substation.

[0040] The queue vehicle information includes: the number of queued vehicles, the queued vehicle license plate, the queued vehicle color, the queued vehicle sequence, the queued vehicle model (battery model) and the estimated queue time. The battery replacement order of each vehicle can be confirmed based on the queued vehicle sequence, queued vehicle license plate and queued vehicle color; the substation to which the vehicle belongs can be divided according to the number of queued vehicles, and it can be judged whether the substation exceeds the upper limit (the queued vehicles exceed the number of batteries, or exceed the substation workload / battery charging speed); according to the queued vehicle model, it can be judged whether the vehicle can be replaced at the battery replacement station and at which substation to replace the battery; the substation to which the vehicle belongs can also be divided according to the estimated queue time.

[0041] It should be noted that each time the second geographical location range of the vehicle is obtained, it needs to be compared with the first geographical location range to confirm the substation matched with the vehicle.

[0042] See also Figure 2 , Figure 2 The figure is an overall flow chart of a method for acquiring queuing vehicle information according to the present invention.

[0043] Optionally, the step of matching the second geographical location range with multiple first geographical location ranges corresponding to each substation respectively to obtain the queue vehicle information of each substation includes: matching the second geographical location range with the first geographical location range; when the second geographical location range matches the first geographical location range, adding the vehicle corresponding to the second geographical location range to the queue of the substation corresponding to the first geographical location range to obtain the queue vehicle information of each substation.

[0044] Specifically, by matching the second geographical location range with the first geographical location range, the vehicle is put into the queue of each substation, thereby obtaining the queue vehicle information of each substation.

[0045] Optionally, the step of matching the second geographical location range with multiple first geographical location ranges corresponding to each substation to obtain queuing vehicle information of each substation also includes: when the second geographical location range does not match the multiple first geographical location ranges, obtaining the first vehicle corresponding to the second geographical location range; judging whether there is a first substation in the battery swap station that is not equipped with a queuing electronic fence based on the queuing electronic fences of each substation in the battery swap station; if so, adding the first vehicle to the queue of the first substation to obtain queuing vehicle information of each substation; if not, deleting the first vehicle.

[0046] By matching the second geographic location range with each first geographic location range, the queued vehicles and non-queued vehicles within the preset range of the battery swap station can be quickly identified, so that when confirming the queued vehicle information of each substation, the non-queued vehicles can be eliminated to avoid non-queued vehicles being included in the queued vehicle information. Among them, the vehicles corresponding to the second geographic location range that matches the first geographic location range are queued vehicles; in the absence of a queuing electronic fence, the vehicles corresponding to the second geographic location range that does not match the first geographic location range are all non-queued vehicles.

[0047] When the second geographical location range corresponding to the vehicle does not match the first geographical location range of each substation, it is possible to further determine whether there is a substation in the battery swap station that does not have a queuing electronic fence. In the case that there is a substation without an electronic fence, the vehicle can still be a queuing vehicle (that is, the vehicle is not in the queuing area of ​​other substations with electronic fences, and it is queuing at a substation without an electronic fence), and the vehicle needs to be placed in the queuing queue of the substation that does not have a queuing electronic fence. If there is no substation without an electronic fence, the vehicle is not in the queuing area of ​​each substation, the vehicle is not a queuing vehicle (non-queuing vehicle), and it can be deleted directly.

[0048] Optionally, when it is determined according to the queuing vehicle information that the target vehicle among all the vehicles has multiple matching substations, before the step of determining the target substation that uniquely matches the target vehicle according to the substation positions of each substation in the battery swap station and / or the queuing vehicle information, the method further includes: determining the currently traversed target vehicle; obtaining the number of the target vehicles in the queuing vehicle information; and when there are multiple target vehicles in the queuing vehicle information, confirming that the target vehicle has multiple matching substations.

[0049] The first geographical location range may have multiple matching substations, so when confirming the queuing vehicle information of each substation based on the second geographical location range and the first geographical location range, the vehicle can be placed in the queuing queues of multiple substations. In order to ensure the uniqueness of the vehicle in the queuing vehicle information, it is necessary to determine whether the number of vehicles in the queuing vehicle information is one; if not, it is necessary to obtain multiple substations matching the target vehicle, and then select again from the multiple matching substations to complete the confirmation of the queuing queue of the target vehicle.

[0050] There may be multiple matching substations within the first geographic location range, so there may be duplicate vehicles in the queue vehicle information. In order to confirm the unique substation that the vehicle matches, it is necessary to obtain the duplicate vehicles (target vehicles) and their corresponding substations, so that after the unique substation that the vehicle matches is subsequently confirmed, it is deleted from other substations, and finally there are no duplicate vehicles in the queue vehicle information.

[0051] S13: When it is determined according to the queuing vehicle information that the target vehicle among all the vehicles has multiple matching substations, a uniquely matching target substation for the target vehicle is determined according to the substation positions of the substations in the battery swap station and / or the queuing vehicle information.

[0052] The target vehicle is a vehicle having multiple matching substations, that is, the first geographical location range corresponding to the second geographical location range where the vehicle is located has multiple matching substations.

[0053] The target substation is the only substation to which the target vehicle finally belongs among the multiple matching substations (i.e., the substation to which the target vehicle finally belongs is the target substation). In other embodiments, the target substation may also be the only substation to which the target vehicle finally belongs among all substations.

[0054] Based on the location of each substation and the location of the vehicle (i.e., the second geographic location range), the battery swap distance from the vehicle to each substation can be calculated, so that the target substation of the vehicle can be confirmed based on the battery swap distance between the target vehicle and its multiple matching substations. For example, if the distance between substation a and the vehicle is 20 meters, and the distance between substation b and the vehicle is 7 meters, substation b with the shortest battery swap distance can be selected as the target substation.

[0055] Based on the queue vehicle information (the number of queue vehicles and the estimated queue time at each substation, etc., and the vehicle model and brand information can also be obtained through the camera), the substation with the least queue vehicles or the shortest estimated queue time can be obtained, and then used as the target substation of the target vehicle. For example, substation a has 7 vehicles and substation b has 5 vehicles, substation b with the fewest queue vehicles is used as the target substation; substation a is expected to have a queue time of 5 minutes and substation b is expected to have a queue time of 4 minutes, substation b with the shortest estimated queue time is used as the target substation.

[0056] By obtaining the target substation based on the substation location and queued vehicle information, the target substation of the vehicle can be determined more accurately. For example, when the battery swapping distance between the matched multiple substations and the target vehicle is the same, the target substation of the target vehicle can also be confirmed based on the number of queued vehicles and the expected queueing time at the matched multiple substations; when the number of queued vehicles and / or the expected queueing time at the matched multiple substations are the same, the target substation of the target vehicle can also be confirmed based on the battery swapping distance between the vehicle and the substation.

[0057] Optionally, when it is determined according to the queuing vehicle information that the target vehicle among all the vehicles has multiple matching substations, the step of determining the target substation that uniquely matches the target vehicle according to the substation positions of each substation in the battery swap station and / or the queuing vehicle information includes: when it is determined according to the queuing vehicle information that the target vehicle among all the vehicles has multiple matching substations, obtaining the first number of queuing vehicles of the multiple matching substations according to the queuing vehicle information; obtaining the second substation with the least number of the first queuing vehicles among the multiple matching substations, and confirming whether the number of the second substation is unique; when the number of the second substation is unique, placing the target vehicle into the queuing vehicle information of the second substation.

[0058] When the vehicle is a queued vehicle (i.e., it needs to go to the battery swap station for battery swapping) (in this case, the target vehicle has not yet been placed in each substation, i.e., the target vehicle does not exist in the queued vehicle information), obtain the number of first queued vehicles corresponding to each substation in the battery swap station (e.g., substations a, b, c, and d match the target vehicle; substation a has 5 vehicles queued; substation b has 4 vehicles queued; substation c has 4 vehicles queued; substation d has 3 vehicles queued), and directly place the vehicle in the second substation / substation d with the least number of queued vehicles.

[0059] Optionally, when it is determined based on the queuing vehicle information that the target vehicle among all the vehicles has multiple matching substations, the step of determining the target substation that uniquely matches the target vehicle based on the substation positions of each substation in the battery swap station and / or the queuing vehicle information also includes: when the number of the second substations is not unique, obtaining the substation positions of multiple second substations; obtaining the battery swapping distance between the target vehicle and the multiple second substations based on the substation positions and the second geographical location range corresponding to the target vehicle; and setting the second substation with the shortest battery swapping distance as the target substation of the target vehicle.

[0060] If there are multiple second substations with the least number of queued vehicles (for example, substation a has 5 vehicles, substation b has 4 vehicles, substation c has 3 vehicles, and substation d has 3 vehicles), the substation locations of these substations (substations c and d) can be obtained. Then, the battery swap distance between these two substations and the target vehicle is obtained by combining the second geographical location range of the vehicle and the substation locations of substations c and d (for example, the distance between substation c and the vehicle is 10 meters, and the distance between substation d and the vehicle is 5 meters). After confirming the battery swap distance between the substation and the vehicle, obtain the substation with the closest battery swap distance (such as substation d), and then put the target vehicle into the queue vehicle information of substation d.

[0061] Optionally, when it is determined according to the queuing vehicle information that the target vehicle among all the vehicles has multiple matching substations, the step of determining the target substation that uniquely matches the target vehicle according to the substation positions of each substation in the battery swap station and / or the queuing vehicle information includes: when the target vehicle among all the vehicles has multiple matching substations, sequentially acquiring the number of queuing vehicles corresponding to the multiple substations according to the arrangement order of each substation in the battery swap station and the queuing vehicle information; when the number of queuing vehicles at the substation ranked first among the multiple substations exceeds a threshold, selecting the next substation as the target substation of the target vehicle according to the arrangement order.

[0062] After confirming that the target vehicle matches multiple substations (e.g., substations b, c, and e), the order of the substations is obtained according to the order of each substation, and then the number of queued vehicles in the substation with the highest order (substation b) is obtained. If the number of queued vehicles has reached or exceeded the workload limit of substation b (i.e., there are 10 batteries in substation b and the number of queued vehicles reaches 10 or more), the target vehicle is placed in the next-ranked substation c. If the number of queued vehicles in the substation also reaches or exceeds the threshold, it is placed in substation e.

[0063] In another embodiment, if there is only one queue at the battery swap station, when obtaining the information of the vehicles in the queue at each substation, the target substation to which each vehicle belongs can be directly determined based on the queue order of the vehicles in the queue and the threshold of the number of vehicles in the queue at the substation. For example, there are 35 vehicles in the queue, and the battery swap station has 3 substations a, b and c, and the threshold of each substation is 10 vehicles. At this time, according to the queue order of the vehicles, vehicles 1-10 are placed in substation a, vehicles 11-20 are placed in substation b, and vehicles 21-30 are placed in substation c, and the other vehicles are waiting in line. In another embodiment, vehicles ranked 1 can be placed in substation a, vehicles ranked 2 can be placed in substation b, vehicles ranked 3 can be placed in substation c, vehicles ranked 4 can be placed in substation a, vehicles ranked 5 can be placed in substation b..., and so on, in sequence until substations a, b and c have reached the threshold (subsequent detection is continued, and if it is detected that a vehicle in the substation has completed battery replacement and left, subsequent vehicles will continue to be placed in. For example, if the vehicle ranked 2 in substation b completes battery replacement first, the vehicle ranked 31 will be placed in substation b (it can also be re-sorted and re-formed)).

[0064] S14: updating the queued vehicle information corresponding to each substation in the battery swap station according to the target substation.

[0065] After confirming the target substation to which the target vehicle belongs, the target vehicle can be deleted from the queues of other substations except the target substation, thereby updating the queue vehicle information, and finally obtaining the queue vehicle information of each substation without duplicate vehicles.

[0066] Optionally, a third geographical location range belonging to multiple substations in the first geographical location range can also be obtained. Match the first geographical location range with the second geographical location range to confirm the substation corresponding to each vehicle. Then match the second geographical location range with the third geographical location range to determine whether the vehicle corresponds to multiple substations. If a vehicle corresponds to multiple substations, obtain the number of queued vehicles and / or substation positions (i.e., the battery exchange distance between the substations) corresponding to the multiple substations; the vehicle can be directly placed in the substation with a short battery exchange distance, and then the vehicle can be deleted from other substations; the vehicle can also be directly placed in the substation with fewer queued vehicles, and then the vehicle can be deleted from other substations; if the battery exchange distances or the number of queued vehicles of the corresponding multiple substations are consistent, continue to calculate the number of queued vehicles or the battery exchange distance; if they are still consistent, the vehicle can be placed in the substation with a higher substation ranking (e.g., substation a, b, c, placed in substation a; substation 2, 3, 4, placed in substation 2).

[0067] Optionally, the queuing substation of the vehicle can also be confirmed based on the vehicle model / brand of the vehicle. Different substations have different battery specifications (e.g., substation a is for battery replacement of brand A vehicles, and substation b is for battery replacement of brand B and C vehicles; substation a is for battery replacement of model A, and substation b is for battery replacement of models B and C). The battery specifications of the vehicle are identified based on the vehicle model / brand of the vehicle, thereby confirming the substation corresponding to the battery specification, and finally confirming the target substation where the vehicle can be replaced, so that the vehicle can be counted into the target substation for queuing).

[0068] Optionally, the target substation can also be selected for the vehicle based on the estimated battery replacement duration / replacement time of each substation. Different battery replacement procedures and replacement speeds of the substations will result in different estimated battery replacement durations / replacement times for the vehicle. For example, if the estimated battery replacement time for the vehicle queued at substation a is 5 minutes, the estimated battery replacement time at substation b is 3 minutes, and the estimated battery replacement time at substation c is 4 minutes, then the vehicle will be placed in substation b (i.e., substation b is the target substation for the vehicle, and the number of queued vehicles in the above substations can be the same or different).

[0069] The method for obtaining queuing vehicle information provided in this embodiment, when there are multiple battery swap stations at the same location (i.e., one battery swap station has multiple substations), can identify whether the vehicles within the preset range are queuing vehicles (i.e., vehicles that need to enter the battery swap station for battery swapping) based on the range of the electronic fences of the multiple battery swap stations (i.e., substations). If the vehicle is identified as a queuing vehicle, continue to determine the battery swap station (i.e., substation) where it is queuing, or the battery swap station (i.e., substation) where it is expected to queue. The battery swap station (i.e., substation) where the vehicle is queuing and expected to queue can be confirmed based on the range of the electronic fence, the number of queuing vehicles at each substation, the battery swapping distance between each substation, the battery specifications, and the expected battery swapping time. This can avoid the problem of duplicate vehicles in the queues of multiple substations and the inability of vehicles to determine the queuing substations.
