[0002] The present application relates to the field of information gathering technology, and in particular to an event location transmission method, device and system. [Background technology]

[0003] Currently, in order to improve security, when collecting event location information during the location transmission process, the collection server often needs to use the data access and operation interface for the map provider map tile provided by the collection server, and then determine the event location information based on the map provider map tile and transmit the obtained event location information.

[0004] However, since map provider map tiles adapted by map service providers are often incompatible, the above-mentioned manner of transmitting event locations is inflexible and not very versatile. Summary of the Invention [Means for solving the problem]

[0034] According to a first aspect, an embodiment of the present application provides an event location transmission method, including:

[0035] The collection server obtains first information of the target event, the first information includes a first location of the target event, the collection server determines general location information of the target event based on the general map tile based on the first information, and the collection server transmits the general location information to at least one receiving server, so as to make the receiving server determine second information based on the general location information, the second information includes a second location of the target event. Based on the above method, a method for determining a target event based on a general map tile is provided. In the transmission process, the dependency of various map providers on the characteristic information of the target event can be effectively reduced, and during the implementation of event location transmission, the compatibility and versatility of the location information of the target event is high, and the requirements for hardware storage and computation resources are reduced. In addition, the location information of the target event obtained based on the general map tile is equal to the encrypted location of the target event, so that the security of the event location transmission can be effectively guaranteed.

[0036] In one possible implementation, if the first location in the first information is a longitude and latitude location of the target event, the collection server converts the first location into general location information based on a conversion rule between longitude and latitude locations and general map tiles.

[0037] According to the above method, when the collecting device of this embodiment of the present application collects the first position of the target event, the obtained first position of the target event can be the longitude and latitude position of the target event. Based on this case, an embodiment of the present application provides a conversion rule between the longitude and latitude position and the general map tile, so that the position information of the target event based on the general map tile can be obtained based on the first position.

[0038] In one possible implementation, if the first location in the first information is the location of a target event determined based on the first map tile, the collection server converts the first location into general location information based on a conversion rule between the first map tile and general map tiles.

[0039] Based on the above method, when the collecting device of this embodiment of the present application collects the first position of the target event, the obtained first position of the target event may be the position of the target event determined based on the first map tile. Based on this case, an embodiment of the present application provides a conversion rule between the first map tile and the general map tile, so that the position information of the target event based on the general map tile can be obtained based on the first position.

[0042] In one possible implementation, the anchor point of the general map tile is a center point or a corner point of the general map tile, or the anchor point of the general map tile is obtained by performing an encoding calculation based on the coordinates of the general map tile.

[0043] Based on the above method, an embodiment of the present application provides several ways to determine the anchor point of the general map tile. For example, the center point or corner point of the general map tile is determined as the anchor point of the general map tile. As another example, the anchor point of the general map tile is obtained by performing an encoding calculation on the coordinates of the general map tile.

[0044] In one possible implementation, the collection server divides the general map tile evenly horizontally and vertically based on the horizontal and vertical coordinates in the encoded coordinates, and determines an anchor point from a first map tile that is evenly divided horizontally and vertically based on the hierarchical coordinates in the encoded coordinates.

[0047] In one possible implementation, conversion rules between general map tiles and map provider map tiles and / or conversion rules between general map tiles and longitude and latitude positions are stored in multiple local storage devices / a single local storage device of the collecting server and / or the receiving server.

[0048] In one possible implementation, conversion rules between general map tiles and map provider map tiles and / or conversion rules between general map tiles and longitude and latitude locations are stored in a third-party storage platform accessible by the collection server and the receiving server.

[0049] It should be noted that a receiving server that stores the above transformation rules is entitled to obtain the transformation rules.

[0050] In one possible implementation, the collection server determines whether authentication of the receiving server was successful based on the receiving server's identifier and a list of identifiers of receiving servers eligible to obtain the conversion rules stored at the collection server.

In addition, the target event location information obtained based on the general map tile is equal to the encrypted location of the target event, so the security of the event location transmission can be effectively guaranteed.

[0053] In one possible implementation, the receiving server converts the general location information into a second location based on a conversion rule between longitude and latitude locations and general map tiles, where the second location is the longitude and latitude location of the target event.

[0054] Based on the above method, in this embodiment of the present application, after receiving general location information, when the receiving server needs to determine the longitude and latitude location of the target event based on the general location information, it can obtain the location information of the target event based on the second map tile, i.e., the second location, based on the conversion rule between the longitude and latitude locations and the general map tile and based on the received general location information.

[0055] In one possible implementation, the receiving server converts the general location information into a second location based on a conversion rule between the second map tile and the general map tile, and the second location is a location of the target event determined based on the second map tile.

[0056] Based on the above method, when the receiving server of this embodiment of the present application collects the first position of the target event, the obtained first position of the target event can be the position of the target event determined based on the general map tile. Based on this case, an embodiment of the present application provides a conversion rule between the first map tile and the general map tile, so that the position information of the target event determined based on the general map tile can be obtained based on the general position information.

[0076] Currently, in order to improve security, when collecting event location information during the location transmission process, the collection server often needs to use the data access and operation interface for the map provider map tile provided by the collection server, and then determine the event location information based on the map provider map tile and transmit the obtained event location information.

[0108] The system architecture and service scenarios described in the embodiments of the present application are intended to more clearly explain the technical solutions of the embodiments of the present application, but are not intended to limit the technical solutions provided in the embodiments of the present application. In addition, those skilled in the art can find that with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of the present application can also be applied to similar technical problems. It should be understood that Figures 1 to 2 are merely simplified schematic diagrams drawn for ease of understanding. The system architecture may further include other devices or may further include other unit modules.

[0109] For ease of understanding, the following explains and describes some terms in the embodiments of the present application.

[0110] (1) Map Tiles: In this embodiment of the application, the map tile pyramid model is a multi-resolution hierarchical model: the resolution decreases from the bottom to the top layer of the tile pyramid, but the geographical extent represented by the tile pyramid remains the same.

[0111] (2) Map tile coordinates: Coordinates can be expressed in three-dimensional coordinates, e.g., (x, y, z), where x and y indicate numbers on the plane and z indicates the tile layer.

[0112] Optionally, in this embodiment of the application, the coordinates of the map tiles can instead be represented as a string of digital information, for example, as 201203. A layer of a tile is represented by using the ones and tens digits of the digital information string together. A number of tiles on the y-axis is represented by using the thousands and hundreds digits of the digital information string together. A number of tiles on the x-axis is represented using the tens digit of the digital information string. In other words, the digital information string 201203 indicates a map tile with an x-axis number of 20, a y-axis number of 12, and a tile layer of 3.

[0113] The map tile coordinate systems used by map providers may differ depending on the map provider, and different map tile coordinate systems have different coordinate system origins, coordinate system axis directions, etc. As a result, the positions of target events obtained based on different map tile coordinate systems are not compatible.

[0114] (3) Source event information file: In this embodiment of the present application, the source event information file is mainly used to describe the basic information of the corresponding target event, such as the first location of the target event. The first location of the target event may be a longitude and latitude location, or may be a location obtained based on the first map provider map tile.

[0115] In addition, the source event information file may further include the severity of the target event (e.g., the severity may be any one of level 10 to level 1, with level 10 representing the lowest level and level 1 representing the highest level), the type of the target event, etc.

[0116] In an optional manner in this embodiment of the present application, the source event information file may be in the form of a table or a document, which is not limited in this embodiment of the present application.

[0117] For example, assume that the source event information file for target event 1 is the file shown in Table 1 below.

[0118] [Table 1]

[0119] In addition, the terms "system" and "network" in the embodiments of the present application may be used interchangeably. "At least one" means one or more, and "multiple" means two or more. The term "and / or" describes a relationship between related objects and indicates that three relationships may exist. For example, A and / or B may represent the following three cases: only A is present, both A and B are present, and only B is present. A and B may be singular or plural. The character " / " generally indicates an "or" relationship between related objects. At least one of the following items, or similar expressions thereof, refers to any combination of these items, including any combination of singular items or multiple items. For example, at least one of a, b, or c may refer to a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c may be singular or plural.

[0120] Unless otherwise specified, ordinal numbers such as "first" and "second" referred to in the embodiments of the present application are used to distinguish between multiple objects and are not intended to limit the order, chronology, priority, or importance of the multiple objects. In addition, the terms "include" and "have" in the embodiments, claims, and accompanying drawings of the present application are not exclusive. For example, a process, method, system, product, or device that includes a series of steps or modules is not limited to the steps or modules listed, and may further include steps or modules that are not listed.

[0121] Furthermore, the event location transmission method provided in an embodiment of the present application is mainly applied to the system architecture shown in Figure 1. In this embodiment of the present application, the event location transmission system architecture includes at least one collection server and at least one receiving server.

[0122] Specifically, as shown in FIG. 3, the event location sending method provided in this embodiment of the present application includes the following steps:

[0123] S300: A collection server obtains first information of a target event, where the first information includes a first location of the target event.

[0124] In this embodiment of the present application, the first information of the target event can be understood as a source event information file of the target event obtained by the collection server.

[0125] In this embodiment of the present application, the first location of the event of interest may be the longitude and latitude location of the event of interest, or may be the first location of the event of interest obtained based on the first map tile.

[0126] S301: The collection server determines, based on first information, how to convert a first location into general location information, where the general location information is a location of a target event determined based on a general map tile.

[0127] S302: The collection server converts the first location in the first information into general location information according to a method for converting a first location into general location information.

[0128] In the optional manner of this embodiment of the present application, in practical application, a conversion interface of a general map tile may be provided in the collection server. The conversion interface of the general map tile has the function of determining a conversion method of general location information, and converting the first information into general location information according to the conversion method of general location information. Therefore, the content of S301 and S302 may be further simplified to input the first information into the conversion interface of the general map tile to obtain general location information.

[0129] S303: The collecting server transmits the general location information to the corresponding receiving server.

[0130] In this embodiment of the present application, there is a corresponding relationship between the collecting server and the receiving server, for example, one collecting server corresponds to multiple receiving servers, or one collecting server corresponds to one receiving server.

[0131] In an optional manner of this embodiment of the present application, the collection server of this embodiment of the present application can determine the receiving server to which the general location information needs to be sent based on the corresponding relationship between the collection server identifier and the receiving server identifier.

[0132] S304: The receiving server receives the general location information.

[0133] S305: The receiving server determines, based on the general location information, a conversion method to be used to obtain the second information.

[0134] S306: The receiving server converts the general location information into second information according to the conversion method used to obtain the second information, where the second information includes a second location of the event of interest.

[0135] In an optional manner of this embodiment of the present application, in practical application, a conversion interface of a general map tile may be provided in the receiving server. The conversion interface of the general map tile has the function of determining the conversion method of the second information, and converting the general location information into the second information according to the conversion method of the second information. Therefore, the content of S305 and S306 may be further simplified to input the general location information into the conversion interface of the general map tile to obtain the second information.

[0136] It should be noted that in this embodiment of the present application, the receiving server that executes the event location transmission method of the present application together with the collection server is the receiving server authenticated by the collection server of this embodiment of the present application. In this embodiment of the present application, the receiving server authenticated by the collection server can be understood as the receiving server that is entitled to obtain the conversion rules between the general map tiles and the map provider map tiles of this embodiment of the present application, and / or the receiving server that is entitled to obtain the conversion rules between the general map tiles and the longitude and latitude positions of this embodiment of the present application.

[0137] In an optional manner in this embodiment of the present application, the collection server in this embodiment of the present application may determine whether authentication of the receiving server was successful based on the identifier of the receiving server.

[0138] For example, assume that the collection server locally stores a list of identifiers of receiving servers that are eligible to obtain transformation rules, such as those shown in Table 2 below.

[0139] [Table 2]

[0140] Suppose the receiving servers served by the collecting server are receiving servers 1-5. It can be seen from the contents of Table 2 that after the collecting server obtains the first location of the target event, the collecting server can use the event location sending method of this embodiment of the present application together with the receiving servers 1-3. In this case, the collecting server can send the general location information to the receiving servers 1-3 after determining the general location information corresponding to the first location.

[0141] Furthermore, in this embodiment of the present application, the conversion rules between general map tiles and map provider map tiles and / or the conversion rules between general map tiles and longitude and latitude positions may be stored in multiple local storage devices / a single local storage device of the collection server and / or the receiving server (which is eligible to obtain the conversion rules). As another example, the conversion rules may be stored in a third-party storage platform accessible by the collection server and the receiving server, which is not limited in this embodiment of the present application.

[0142] According to this embodiment of the present application, a method for determining a target event based on a general map tile is provided. In the transmission process, the dependency of various map providers on the characteristic information of the target event can be effectively reduced, and during the implementation of event location transmission, the compatibility and versatility of the target event location information is high, and the requirements for hardware storage and computation resources are reduced. In addition, the general location information of the target event obtained based on the general map tile is equal to the encrypted location of the target event, so the security of the event location transmission can be effectively guaranteed.

[0143] Furthermore, there are multiple cases for the general map tiles used in the embodiments of the present application, and are not particularly limited to the following several cases.

[0144] General map tile 1: In this embodiment of the present application, a map provider map tile in the map provider map tile library is determined as the general map tile to be used in the embodiment of the present application.

[0145] For example, assume there are five map provider map tiles in a map provider map tile library, say a map tile from map provider A, a map tile from map provider B, a map tile from map provider C, a map tile from map provider D, and a map tile from map provider E.

[0146] In the present embodiment of the present application, a map provider map tile may be selected from the five map provider map tiles as a general map tile used in the embodiment of the present application, for example, a map tile of map provider A is selected as a general map tile.

[0147] General map tile 2: In this embodiment of the present application, the flat map is divided based on a predefined division rule to obtain a general map tile.

[0148] Specifically, tile division is performed on the planar map based on a predetermined division rule to obtain at least one layer of general map tiles, and each layer of general map tiles includes at least one general map tile. A coordinate system of the general map tiles is set, and coordinates of the general map tiles are determined based on the set coordinate system of the general map tiles.

[0149] For better presentation, points in three-dimensional space are often mapped to two-dimensional space in a projection manner, which establishes a one-to-one correspondence between points on the Earth's surface and points on the projection plane, as shown in Fig. 4. For example, Internet maps usually map points in three-dimensional space to two-dimensional space in a Mercator projection to obtain a flat map.

[0150] Then, tile division is performed on the obtained flat map. If one layer of tiles is obtained after tile division on the flat map, the layer contains one tile. If two layers of tiles are obtained after tile division on the flat map, a flat map with level 0 contains one tile and a flat map with level 1 contains at least two tiles.

[0151] In the optional manner of this embodiment of the present application, the anchor point of the general map tile is used as the anchor point of the map provider map tile corresponding to the general map tile. For example, the map tile of the map provider A is selected as the general map tile. In this case, the anchor point determination manner of the map tile of the map provider A is the anchor point determination manner of the general map tile.

[0152] In another optional manner of this embodiment of the present application, the anchor point of the general map tile is a fixed point within the general map tile, for example, a center point or a corner point of the general map tile is determined as the anchor point of the general map tile.

[0153] In another optional manner of this embodiment of the present application, the anchor point of the general map tile is determined based on the coordinates of the general map tile.

[0154] For example, the anchor point of a general map tile is obtained by performing an encoding calculation based on the coordinates of the general map tile.

[0155] Specifically, the first map tile is divided evenly horizontally and vertically based on horizontal and vertical coordinates in the encoding coordinates, and the anchor point is determined from the first map tile divided evenly horizontally and vertically based on hierarchical coordinates in the encoding coordinates.

[0156] The encoding method multiplies x, y, and z in the coordinates (x, y, z) by the coefficient k corresponding to them to obtain the encoded coordinates (kx, ky, kz).

[0157] For example, if the coordinates of a general map tile are (9, 9, 3), encoding is performed on the coordinates (9, 9, 2). The encoding coefficient k is 7, and the encoded coordinates are (63, 63, 21).

[0158] Then, as shown in FIG. 5, the general map tile is divided equally in the horizontal direction based on the absolute value of the most significant digit of the x value in the coding coordinate, i.e., the absolute value of the most significant digit of the x value in the coding coordinate is 6, so the general map tile is divided equally in the horizontal direction into 6 parts. The general map tile is divided equally in the vertical direction based on the absolute value of the most significant digit of the y value in the coding coordinate, i.e., the absolute value of the most significant digit of the y value in the coding coordinate is 6, so the general map tile is divided equally in the vertical direction into 6 parts. Finally, as shown in FIG. 5, a point in the general map tile divided equally in the horizontal and vertical directions that corresponds to the most significant digit of the z value in the coding coordinate is determined as the anchor point. In other words, a second point in the general map tile divided equally in the horizontal and vertical directions into 6x6 parts is determined as the anchor point.

[0159] In addition, in this embodiment of the present application, after the general map tile is determined, it is necessary to further determine a conversion method between the general map tile and at least one map provider map tile and / or a conversion method between the general map tile and a longitude and latitude position based on the general map tile, which will be described separately below.

[0160] Case 1: A conversion method between a general map tile and at least one map provider map tile is determined in this embodiment of the present application.

[0161] In an optional manner of this embodiment of the present application, the method for transforming a general map tile into at least one map provider map tile determines a coordinate shift from the general map tile to the map provider map tile based on a coordinate system of the general map tile and a coordinate system of the map provider map tile, and the method for transforming at least one map provider map tile into a general map tile determines a coordinate shift from the map provider map tile to the general map tile.

[0162] For example, the conversion of map provider C's map tiles to general map tiles is used as an example for illustration.

[0163] Assume that the coordinate system of the map tile of map provider C is shown in (a) of Fig. 6 and the coordinate system of the general map tile is shown in (b) of Fig. 6. It can be seen that the coordinate shift of the general map tile relative to the map tile of map provider C includes a horizontal coordinate shift of 2 units and a vertical coordinate shift of 1 unit.

[0164] Therefore, it can be seen from this coordinate shift that a method of transforming a general map tile into map provider C's map tile involves shifting the horizontal coordinate two units to the right and the vertical coordinate one unit up, and a method of transforming map provider C's map tile into a general map tile involves shifting the horizontal coordinate two units to the left and shifting the vertical coordinate two units down.

[0165] It should be noted that the above-mentioned conversion method between the general map tile and the map provider map tile is merely an example and does not limit the present embodiment of the present application. In the present embodiment of the present application, the conversion method between the general map tile and the map provider map tile may be set in multiple ways based on the actual situation. For example, the conversion process between the general map tile and the map provider map tile may also use encryption coding, that is, the conversion is not as simple as the coordinate system conversion shown in FIG. 6. The encryption coding may be a function mapping relationship or a dynamic encryption coding method, which is not limited in the present embodiment of the present application.

[0166] Furthermore, in this embodiment of the present application, after the conversion method between the general map tile and at least one map provider map tile is determined, the correspondence relationship between the conversion methods between the general map tile and the map provider map tile can be stored. For example, the correspondence relationship may be stored in multiple local storage devices / a single local storage device of the collection server and / or the receiving server. As another example, the correspondence relationship may be stored in a third-party storage platform accessible by the collection server and the receiving server. This is not limited in this embodiment of the present application.

[0167] For example, assume that the correspondence in the conversion method between general map tiles and map provider map tiles is as shown in Table 3 below.

[0168] [Table 3]

[0169] Assuming that the first location of the target event obtained by the collection server is determined based on the map tile of map provider A, the collection server converts the location information of the target event based on the map tile of map provider A into location information of the general map tile according to the corresponding conversion method 1 used to convert the map tile of map provider A into a general map tile.

[0170] In an optional manner of this embodiment of the present application, when the first location obtained by the collection server is determined based on the map provider map tile, the first information collected by the collection server and including the first location may further include identification information of the map provider map tile, so that the collection server can determine the conversion method based on the identification information.

[0171] Case 2: The conversion method between general map tiles and longitude and latitude positions is determined in this embodiment of the present application.

[0172] In case 2, the collection server needs to further set a conversion method between the general map tile and the latitude and longitude position. There may be multiple methods for converting between the general map tile and the latitude and longitude position. For example, in this embodiment of the present application, the conversion method between the general map tile and the latitude and longitude position in this embodiment of the present application may be determined based on the method of calculating the correspondence relationship between the map provider map tile and the latitude and longitude position.

[0173] Furthermore, in the actual process of transmitting the event location, the above event location transmitting method can be detailed as three stages, for example, a collecting stage, an encoding stage, and a decoding stage, which are described separately below.

[0174] Phase 1: Collection Phase In the collection stage of this embodiment of the present application, the collection server mainly obtains first information of a target event, where the first information includes a first location of the target event.

[0175] In this embodiment of the present application, there are multiple cases for the first location collected by the collection server, and is not particularly limited to the following cases.

[0176] Case 1: The first location of the target event obtained by the collection server is the longitude and latitude location of the target event.

[0177] Case 2: The first location of the target event obtained by the collection server is location information based on the map provider map tile.

[0178] Further, in case 2, in an optional manner of this embodiment of the present application, the first information collected by the collection server further includes an identifier of the map provider map tile.

[0179] In an optional manner of this embodiment of the present application, the first position is represented by using the coordinates of the map tile and the position shift of the target event relative to the anchor point of the map tile, so that the position, area shape, etc. of the target event can be obtained based on the first position.

[0180] The shape of the area of ​​the target event may be in various forms, such as a point, a line, or a plane, or may be a combination of a plurality of points, a plurality of lines, a plurality of planes, or the like.

[0181] For example, as shown in Fig. 7, assume that the target event is a polygon as shown in the figure, and the center point of the map tile where the target event is located is selected as the anchor point. Therefore, by using the position shift of the target event relative to the anchor point and the coordinates of the map tile where the target event is located, the specific position, area shape, etc. of the target event can be described.

[0182] Phase 2: Encoding Phase It is to be understood that in this embodiment of the present application, the collection server converts the collected first location of the target event into general location information based on the general map tile in the encoding step. In other words, the collection server obtains the general location information of the target event based on the general map tile by encoding the collected first location of the target event.

[0183] For example, assume that the first location included in the first information collected by the collection server is the longitude and latitude location of the target event.

[0184] The collection server converts the first position into general position information according to a conversion method between the longitude and latitude positions and the general map tile, where the general position information includes a coordinate of the general map tile and a position shift relative to an anchor point of the general map tile.

[0185] For example, assume that the first location included in the first information collected by the collection server is location information of a target event determined based on the map tile of map provider C. The collection server determines a conversion method between the map provider map tile and a general map tile based on the identifier of the map tile of map provider C. For example, the conversion method between the map provider C's map tile and a general map tile is determined to be conversion method 6.

[0186] In this case, the collection server converts the first position into general position information according to conversion method 6. The general position information includes the coordinates of the general map tile and a position shift relative to the anchor point of the general map tile.

[0187] Phase 3: Decryption Phase In this embodiment of the present application, the decoding step can be understood as a step of converting the target event into second information of the target event based on the general location information determined based on the general map tile. In other words, the collection server obtains the second information of the target event by decoding the received general location information of the target event.

[0188] In this embodiment of the present application, the second information includes a second location of the target event, the second location may be a longitude and latitude location of the target event, or the second location may be location information of the target event obtained based on the second map tile.

[0189] The receiving server in this embodiment of the present application may be a map provider working with the collection server and / or an associated management department. The second map tile is a map tile adapted to the receiving server.

[0190] For example, assume that the second location of the target event that needs to be determined by the receiving server is the longitude and latitude location of the target event. In this case, the receiving server converts the general location information into the second location according to a conversion method between the general map tile and the longitude and latitude location. The general location information includes the coordinates of the general map tile and a location shift relative to the anchor point of the general map tile.

[0191] For example, assume that the second position of the target event that needs to be determined by the receiving server is the position information of the target event that is determined based on the map provider map tile that is adapted to the receiving server. For example, the second position is the position information of the target event that is determined based on the map tile of map provider C. In this case, the receiving server converts the general position information into the second position according to the conversion method between the general map tile and the map tile of map provider C. The general position information includes the coordinates of the general map tile and a position shift relative to the anchor point of the general map tile.

[0192] In order to more clearly present the technical solutions provided in the present application, the following provides several embodiments to describe the event location sending method provided in the present application.

[0193] Please note that the following description is only an example of the technical solution provided in this application, and does not limit the technical solution provided in this application. The methods obtained by combining or modifying the following embodiments to solve the technical problems of this application shall fall within the protection scope of this application.

[0194] Embodiment 1: Interaction between one collection server and one receiving server Assume that the current transmission scenario of event location is shown in Figure 8. The collecting server is Vehicle A. The receiving server is Map Provider A. There is one event of interest.

[0195] Vehicle A obtains first information of the target event. The first information may include a type of the target event, a first location of the target event, etc. The first location of the target event may be represented by longitude and latitude, or may be represented based on a map provider map tile.

[0196] Vehicle A obtains general location information of the target event based on the general map tile by inputting first information into a conversion interface of a general map tile provided for vehicle A. The conversion interface of the general map tile is configured to convert the first location into the general location information according to a corresponding conversion method.

[0197] In an optional manner in this embodiment of the present application, the general location information includes the type of the target event, the coordinates of the general map tile, and the shift of the target event relative to the anchor point of the general map tile.

[0198] It should be noted that the conversion interface for general map tiles is configured to convert only location information obtained based on map tiles of certified map providers.

[0199] The collection server transmits the general location information to the receiving server.

[0200] To further ensure security, the collection server can encrypt the general location information and transmit the encrypted general location information to the receiving server.

[0201] After receiving the general location information, the receiving server inputs the general location information and an identifier of the map provider map tile adapted to the receiving server into a conversion interface of the general map tile to obtain location information of the target event based on the map provider map tile adapted to the receiving server, or obtains information about the longitude and latitude position of the target event by inputting the general location information into the conversion interface of the general map tile.

[0202] Embodiment 2: Interaction between multiple collection servers and multiple receiving servers Assume that the current transmission scenario of event locations is shown in Figure 9. The collecting servers are Vehicle A and Roadside Unit A. The receiving servers are Map Provider A and Map Provider B. Currently, there are three events of interest, namely, Event of Interest 1, Event of Interest 2, and Event of Interest 3.

[0203] Vehicle A obtains first information on target event 1. The first information on target event 1 may include a type of target event 1, a first location of target event 1, etc. Roadside unit A obtains first information on target event 2 and first information on target event 3. The first information on target event 2 may include a type of target event 2, a first location of target event 2, etc. The first information on target event 3 may include a type of target event 3, a first location of target event 3, etc.

[0204] The first location of the target event may be represented by longitude and latitude, or may be represented based on map provider map tiles. For ease of explanation, in this embodiment of the present application, it is assumed that the first locations corresponding to the target events 1 to 3 are all location information obtained based on map tiles.

[0205] Vehicle A obtains general position information of target event 1 based on the general map tile by inputting first information of target event 1 into a conversion interface of the general map tile adapted to vehicle A. Roadside unit A obtains general position information of target event 2 based on the general map tile by inputting first information of target event 2 into a conversion interface of the general map tile adapted to roadside unit A. Roadside unit A obtains general position information of target event 3 based on the general map tile by inputting first information of target event 3 into a conversion interface of the general map tile adapted to roadside unit A.

[0206] The conversion interface of the general map tile is configured to convert the first location of the target event into general location information of the target event according to a corresponding conversion method.

[0207] In an optional manner in this embodiment of the present application, the general location information includes the type of the target event, the coordinates of the general map tile, and the shift of the target event relative to the anchor point of the general map tile.

[0208] It should be noted that the conversion interface for general map tiles is configured to convert only location information obtained based on map tiles of certified map providers.

[0209] Further, it is assumed that the correspondence between the collection servers and the receiving servers is as shown in Table 4 below.

[0210] [Table 4]

[0211] After obtaining the general position information of target event 1, vehicle A transmits general position information 1 of target event 1 to map provider A and map provider B based on the contents of Table 2. After obtaining the general position information of target event 2, roadside unit A transmits general position information 2 of target event 2 to map provider A and map provider B based on the contents of Table 2. After obtaining the general position information of target event 3, roadside unit A transmits general position information 3 of target event 3 to map provider A and map provider B based on the contents of Table 2.

[0212] After receiving the general location information 1 of the target event 1, the map provider A obtains the location information of the target event 1 based on the map provider A's map tile by inputting the general location information 1 and the identifier of the map provider A's map tile into the conversion interface of the general map tile.

[0213] Optionally, map provider A can also obtain the longitude and latitude location information of the target event 1 by inputting general location information 1 into the conversion interface of the general map tile.

[0214] After receiving the general location information 2 of the target event 2, the map provider A obtains the location information of the target event 2 based on the map provider A's map tile by inputting the general location information 2 and the identifier of the map provider A's map tile into the conversion interface of the general map tile.

[0215] Optionally, map provider A can also obtain the longitude and latitude location information of the target event 2 by inputting general location information 2 into the conversion interface of the general map tile.

[0216] After receiving the general location information 3 of the target event 3, the map provider A obtains the location information of the target event 3 based on the map provider A's map tile by inputting the general location information 3 and the identifier of the map provider A's map tile into the conversion interface of the general map tile.

[0217] Optionally, map provider A can also obtain the longitude and latitude location information of the target event 3 by inputting general location information 3 into the conversion interface of the general map tile.

[0218] Similarly, after receiving the general location information of the target event, map provider B obtains the location information of the target event based on map provider B's map tile by inputting the general location information and the identifier of map provider B's map tile into the conversion interface of the general map tile.

[0219] Optionally, map provider B can also obtain the longitude and latitude location information of the target event by inputting general location information into the conversion interface of the general map tile.

[0220] To ensure better security, the vehicle A and / or the roadside unit A may encrypt the general location information and transmit the encrypted general location information to a corresponding receiving server.
