[0047] The present application embodiment provides a charging station data update method, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the charging station data updating method of the present application.
[0048] In this embodiment, the charging station data updating method includes the following steps:
[0049] Step S10: determining the charging station type of the current charging station according to the original charging station data of the current charging station.
[0050] It should be noted that the execution subject of the method of this embodiment can be a terminal device with data update, data processing and program running functions, such as a smart phone, a computer, etc., or an electronic device with the same or similar functions, such as the above-mentioned charging station data update device. The following takes the charging station data update device as an example to illustrate this embodiment and the following embodiments.
[0051] It is understandable that the above-mentioned current charging station may refer to a station that provides charging services for electric vehicles, and the above-mentioned original charging station data may refer to the initial data stored in the current charging station, such as the charging station name, charging station location, charging pile information, charging gun information, etc. This embodiment does not limit this.
[0052] It should be understood that the above-mentioned original charging station data can be subjected to feature query, and then the charging station type of the current charging station can be determined based on the key features obtained by the query (such as whether it is located near a highway exit, whether it is located in a service area, whether it contains a fast charging port, etc.).
[0053] Step S20: If the charging station type is the first type, the original charging station data is updated according to the highway exit information corresponding to the current charging station.
[0054] It should be noted that the above-mentioned first type may refer to a non-service area charging station type, and the above-mentioned highway exit information may include the name of the highway exit, the identification number, the straight-line distance between the highway exit and the current charging station, and the driving route, etc. This embodiment does not limit this.
[0055] It should be understood that if the charging station type of the current charging station is a non-service area charging station type, it means that the vehicle needs to exit the highway before reaching the current charging station for charging. Therefore, it is possible to determine how to exit the highway to reach the current charging station by querying the highway exit information corresponding to the current charging station, and update the original charging station data according to the highway exit information.
[0056] Step S30: If the charging station type is the second type, the original charging station data is updated according to the location information of the current service area to which the current charging station belongs.
[0057] The updated original charging station data is used to generate vehicle charging guidance.
[0058] It should be noted that the above-mentioned second type may refer to a service area charging station type, the above-mentioned position information may indicate the direction and position information of the current service area relative to a certain reference object, and the above-mentioned vehicle charging guidance may indicate the driving route guidance for the vehicle to reach the current charging station.
[0059] It should be understood that if the charging station type of the current charging station is a service area charging station type, it means that the vehicle can reach the current charging station for charging by driving normally on the highway. In addition, since most highways cannot turn around, it is necessary to determine the location information of the current service area to which the current charging station belongs, and then update the original charging station data based on the location information to avoid the generated vehicle charging guidance including the service area connected to the opposite lane.
[0060] In combination with the above discussion, the feature of updating the original charging station data according to the highway exit information corresponding to the current charging station allows the user to directly determine how to exit the highway to reach the current charging station based on the updated original charging station data in the actual driving scenario. At the same time, the feature of updating the original charging station data according to the direction information of the current service area to which the current charging station belongs allows the user to determine the service area in the same direction as the vehicle's driving road based on the updated original charging station data in the actual driving scenario, thereby reducing the generation time of the vehicle charging instructions, allowing the user to obtain the driving route instructions to the current charging station more quickly.
[0061] This embodiment determines the charging station type of the current charging station based on the original charging station data of the current charging station; if the charging station type is the first type, the original charging station data is updated according to the highway exit information corresponding to the current charging station; if the charging station type is the second type, the original charging station data is updated according to the location information of the current service area to which the current charging station belongs; wherein the updated original charging station data is used to generate vehicle charging instructions. Since the above method of this embodiment updates the original charging station data according to the highway exit information corresponding to the current charging station when the charging station type of the current charging station is the first type, and updates the original charging station data according to the location information of the current service area to which the current charging station belongs when the charging station type of the current charging station is the second type, it is possible to generate vehicle charging instructions based on the updated original charging station data, thereby achieving the technical effect of quickly finding a suitable charging station for the vehicle in a long-distance high-speed driving scenario.
[0062] refer to Figure 3 , Figure 3 This is a flow chart of a second embodiment of the charging station data updating method of the present application.
[0063] In a feasible implementation manner, the step S10 may include:
[0064] Step S101: acquiring an area of interest corresponding to the current charging station in a digital map according to original charging station data of the current charging station.
[0065] It should be noted that the above-mentioned area of interest (AOI) refers to an area of particular concern or interest to a user in a digital map corresponding to a geographic space. This area can be of any size or shape, such as a block, a specific building or landmark, etc.
[0066] Step S102: If the interest area does not include a service area, determining that the charging station type of the current charging station is a first type.
[0067] Step S103: If the interest area includes a service area, determining that the charging station type of the current charging station is the second type.
[0068] In a specific implementation, if the area of interest corresponding to the current charging station in the digital map does not include a service area, it can be determined that the charging station type of the current charging station is a non-service area charging station type; if the area of interest corresponding to the current charging station in the digital map includes a service area, it can be determined that the charging station type of the current charging station is a service area charging station type.
[0069] In a feasible implementation manner, the charging station data updating method may further include:
[0070] Step S1: when receiving update push information related to target charging station data, extracting first key information contained in the update push message and second key information contained in the target charging station data.
[0071] It should be noted that the above-mentioned first key information and the above-mentioned second key information actually belong to the same information item, but the specific information contained in the information item may be the same or different (depending on whether the key information is updated). The "first" and "second" here are only used to distinguish the key information in the update push message and the key information in the target charging station data.
[0072] In a specific implementation, the first key information contained in the update push message and the second key information contained in the target charging station data can be extracted according to the user's selection criteria for the charging station (i.e., what information will affect the user's choice of charging station). Specifically, the first key information or the second key information may include but is not limited to the charging station ID, the latitude and longitude of the charging station, the station status (normal, closed, medium maintenance), the service rate, the charging type (fast charging, slow charging), etc.
[0073] Step S2: performing hash operations on the first key information and the second key information respectively to obtain a first hash value and a second hash value.
[0074] Step S3: If there is a difference between the first hash value and the second hash value, updating the target charging station data based on the update push information.
[0075] In a specific implementation, the MessageDigest class in Java can be used to implement a hash operation based on MD5 (Message-Digest Algorithm 5) on the first key information and the second key information. The first hash value and the second hash value are actually message digests obtained after a hash operation is performed using the first key information and the second key information as inputs, and the lengths of the first hash value and the second hash value are fixed to facilitate difference comparison.
[0076] Furthermore, if there is a difference between the first hash value and the second hash value (that is, the first hash value is not equal to the second hash value), it indicates that there is an update of key information in the update push message, and therefore the target charging station data can be updated based on the update push information; if there is no difference between the first hash value and the second hash value (that is, the first hash value is equal to the second hash value), it indicates that there is no update of key information in the update push message (there may be an update of non-critical information, but the non-critical information has no reference value for the generation of vehicle charging instructions in this embodiment, so it can be ignored), and there is no need to update the target charging station data at this time.
[0077] This embodiment obtains the interest area corresponding to the current charging station in the digital map according to the original charging station data of the current charging station; if the interest area does not include the service area, the charging station type of the current charging station is determined to be the first type; if the interest area includes the service area, the charging station type of the current charging station is determined to be the second type; when receiving the update push information related to the target charging station data, the first key information contained in the update push message and the second key information contained in the target charging station data are extracted; the first key information and the second key information are hashed respectively to obtain the first hash value and the second hash value; if there is a difference between the first hash value and the second hash value, the target charging station data is updated based on the update push information. The above method of this embodiment uses the interest area corresponding to the current charging station in the digital map to more accurately determine the charging station type of the current charging station, and at the same time, based on the hash values corresponding to the first key information contained in the update push message and the second key information contained in the target charging station data, it is determined whether to update the target charging station data based on the update push information, thereby avoiding unnecessary data updates.
[0078] refer to Figure 4 , Figure 4 This is a flow chart of a third embodiment of the charging station data updating method of the present application.
[0079] In a feasible implementation manner, the step S20 may include:
[0080] Step S201: Perform a reverse geographic query on the location information of the current charging station in the digital map to obtain the highway exit information corresponding to the current charging station.
[0081] Step S202: determining the path distance between the current charging station and the target highway exit according to the highway exit information, and updating the original charging station data based on the path distance.
[0082] It should be noted that reverse geographic query, also known as reverse geocoding or reverse address resolution, is a process of obtaining corresponding structured address information through location information.
[0083] In a specific implementation, after determining the path distance between the current charging station and the target highway exit, if the path distance is less than or equal to a preset threshold (e.g., 3 kilometers), it can be determined that the distance cost consumed by the user from the target highway exit to the current charging station is low, so the original charging station data can be updated to associate the current charging station with the target highway exit; if the path distance is greater than the preset threshold, it can be determined that the distance cost consumed by the user from the target highway exit to the current charging station is high, so the original charging station data can be updated to mark the current charging station as a charging station that is not recommended for use. In particular, the above path distance can include a straight-line distance and a driving distance.
[0084] In a feasible implementation manner, the step S30 may include:
[0085] Step S301: Select a first point and a second point corresponding to a current service area to which the current charging station belongs, wherein the first point is the center point of the city where the current service area is located, and the second point is the entrance point of the current service area.
[0086] Step S302: Calculate the location information of the current service area based on the first point and the second point, and update the original charging station data according to the location information.
[0087] In the specific implementation, it is first necessary to determine the specific location information of the first point and the second point in the digital map, and then the direction information of the current service area can be calculated based on the specific location information. Finally, the direction information is merged with the original charging station data and stored, thereby realizing the update of the original charging station data.
[0088] In a feasible implementation manner, the step S302 may include:
[0089] Step S3021: Obtain first longitude and latitude information and second longitude and latitude information corresponding to the first point and the second point in the digital map respectively.
[0090] Step S3022: Calculate the azimuth information corresponding to the current service area in the preset reference direction according to the first longitude and latitude information and the second longitude and latitude information.
[0091] In a specific implementation, assuming that the above-mentioned azimuth information is the direction angle of the current service area, and the above-mentioned preset reference direction is the clockwise direction of due north, the azimuth information can be calculated based on the following formula:
[0092] θ=arctan2(sin(Δλ),cos(latB)·tan(latA)-sin(latB)·cos(Δλ)).
[0093] Among them, θ represents the direction angle of the current service area, latA represents the GCJ-02 latitude of the first point, latB represents the GCJ-02 latitude of the second point, and Δλ represents the longitude difference between the first point and the second point.
[0094] Furthermore, after determining the direction angle of the current service area and updating it to the original charging station data, the direction angle of the current vehicle and the direction angle of the current service area (the preset reference directions corresponding to the two direction angles are consistent, for example, both are clockwise from due north) can be subtracted. If the absolute value of the difference is less than or equal to the preset angle value (for example, 90 degrees), it can be determined that the current vehicle and the current service area are on the same side of the highway, and the current service area can be recommended to the current vehicle; if the absolute value of the difference is greater than the preset angle value (for example, 90 degrees), it can be determined that the current vehicle and the current service area are not on the same side of the highway, and the current service area can be not recommended to the current vehicle.
[0095] This embodiment obtains the highway exit information corresponding to the current charging station by performing a reverse geographic query on the location information of the current charging station in the digital map; determines the path distance between the current charging station and the target highway exit according to the highway exit information, and updates the original charging station data based on the path distance; selects a first point and a second point corresponding to the current service area to which the current charging station belongs, the first point being the center point of the city where the current service area is located, and the second point being the entrance point of the current service area; obtains first longitude and latitude information and second longitude and latitude information corresponding to the first point and the second point in the digital map, respectively; calculates the azimuth information corresponding to the current service area in a preset reference direction according to the first longitude and latitude information and the second longitude and latitude information, and updates the original charging station data according to the azimuth information. The above method of this embodiment updates the original charging station data according to the path distance between the current charging station and the target highway exit, thereby ensuring that the user can refer to the vehicle charging guidance generated by the updated original charging station data to exit the highway and find the charging station more quickly; at the same time, the direction information of the current service area is calculated through the center point of the city where the current service area is located and the entrance point of the current service area, and then the original charging station data is updated according to the direction information, thereby ensuring that the user can refer to the vehicle charging guidance generated by the updated original charging station data to find the service area on the same side of the highway where the vehicle is currently traveling more quickly.
[0096] In addition, an embodiment of the present application further proposes a storage medium, on which a charging station data update program is stored. When the charging station data update program is executed by a processor, the steps of the charging station data update method described above are implemented.
[0097] Reference Figure 5 , Figure 5 This is a structural block diagram of the first embodiment of the charging station data updating device of the present application.

[0104] Based on the first embodiment of the charging station data updating device of the present application, a second embodiment of the charging station data updating device of the present application is proposed.
[0105] In this embodiment, the type determination module 501 is also used to obtain the area of interest corresponding to the current charging station in the digital map according to the original charging station data of the current charging station; if the area of interest does not include a service area, the charging station type of the current charging station is determined to be the first type; if the area of interest includes a service area, the charging station type of the current charging station is determined to be the second type.
[0106] Furthermore, the first update module 502 is also used to perform a reverse geographic query on the location information of the current charging station in the digital map to obtain the highway exit information corresponding to the current charging station; determine the path distance between the current charging station and the target highway exit according to the highway exit information, and update the original charging station data based on the path distance.
[0107] Furthermore, the second update module 503 is also used to select a first point and a second point corresponding to the current service area to which the current charging station belongs, the first point being the center point of the city where the current service area is located, and the second point being the entry point of the current service area; the orientation information of the current service area is calculated based on the first point and the second point, and the original charging station data is updated according to the orientation information.
