[0021] The speed information real-time prompting method, device, equipment and storage medium provided by the embodiments of the application will be described in detail below with reference to the accompanying drawings, specific embodiments and application scenarios thereof.

[0022] Figure 1 is a flowchart of a speed information real-time prompting method provided by the embodiments of the application. As shown in Figure 1 , the specific steps include the following steps: S101, in the case of speed information prompting for a current participating player, real-time acquisition of positioning information and speed data of each participating player, determination of a current position of the current participating player and a target participating player of a backward adjacent position to the current participating player according to the positioning information.

[0023] The current participating player can be a certain participating player who needs speed information prompting in the current race. The speed information prompting can be real-time speed that needs to be achieved or maintained in the case of maintaining the current race position of the current participating player. The speed information prompting can include a determined real-time speed, and can also include a real-time speed range. The current position can be a real-time ranking of the participating player at the current position in the current race. The target participating player can be a participating player whose current position is behind the current participating player and whose position is adjacent to the current participating player.

[0024] In one embodiment, during a race such as a marathon or a cross-country race, a participant can report speed information through a sports bracelet to request real-time prompts or the system can automatically provide real-time prompts to the participant after the start of the race. In the case of providing real-time speed information to the current participant, the positioning information and speed data of each participant in the race can be obtained in real time, the real-time position coordinates of each participant can be determined according to the positioning information, the distance between each participant and the finish line can be determined according to the finish line position coordinates and the real-time position coordinates of each participant, the participants can be ranked according to the distance, the ranking of each participant can be determined, the current ranking of the current participant can be obtained, and a target participant adjacent to the current ranking of the current participant can be determined.

[0025] In one embodiment, the current ranking of the current participant is determined according to the positioning information, including: determining the instantaneous point positions of each participant in the preset race path according to the positioning information, and determining the path shape of the preset race path; ranking the instantaneous point positions according to the path shape and the preset race running direction, and determining the current ranking of the current participant according to the ranking result.

[0026] In one embodiment, the current ranking of the current participant is determined according to the positioning information, including: determining the instantaneous point positions of each participant in the preset race path according to the positioning information, and determining the path shape of the preset race path; ranking the instantaneous point positions according to the path shape and the preset race running direction, and determining the current ranking of the current participant according to the ranking result.

[0027] In one embodiment, the instantaneous point positions of each participant in the preset race path can be determined according to the positioning information, and the path shape of the preset race path can be determined according to the race map. The position sequence of each instantaneous point position can be determined according to the path shape and the preset race running direction, the instantaneous point positions can be ranked according to the position sequence, and the current ranking of the current participant can be determined according to the ranking result.

[0028] S102, determining a first race segment complexity corresponding to the first positioning information of the current participant and a second race segment complexity corresponding to the second positioning information of the target participant, and determining a speed range for the current participant to maintain the current ranking according to the speed data, the first race segment complexity, and the second race segment complexity.

[0029] The first positioning information can be the positioning information of the current contestant at the current time. The first section complexity can be the passing difficulty of the section where the first positioning information is located. The second positioning information can be the positioning information of the target contestant at the current time. The second section complexity can be the passing difficulty of the section where the second positioning information is located. The section complexity can be data representing the passing difficulty of the contestant. The section complexity is related to the track type, slope, road flatness, and number of turns of the track corresponding to the section. The track type includes flat road, uphill, and downhill.

[0030] In one embodiment, the first section corresponding to the first positioning information of the current contestant can be determined, and the first section complexity can be calculated according to the track type, slope, road flatness, and number of turns of the track corresponding to the first section marked in the track map. The calculation method of the section complexity can be to determine the complexity influence coefficient corresponding to the track type, slope, road flatness, and number of turns according to a preset corresponding relationship, and to add each complexity influence coefficient to obtain the sum. Similarly, the second section complexity corresponding to the second positioning information of the target contestant can be determined. Since different section complexities have different effects on the speed of the contestant, and the current contestant can maintain the current ranking by keeping the real-time speed of the contestant compared with the real-time speed of other contestants, the speed range of the current contestant to maintain the current ranking can be determined by combining the speed data of each contestant and the section complexity of the current section. The size relationship between the first section complexity and the second section complexity can be compared, and in the case that the first section complexity is greater than the second section complexity, it is determined that the current contestant needs to increase the speed, otherwise it is determined that the current contestant can maintain the current speed. In the case that the current contestant needs to increase the speed, the difference between the first section complexity and the second section complexity can be calculated, and the association between the section complexity and the speed data can be determined according to the collected historical competition data, the minimum speed required by the current contestant at the next time can be determined according to the association and the difference, and the speed range of the current contestant to maintain the current ranking is obtained.

[0031] In one embodiment, the first section complexity corresponding to the first positioning information of the current contestant is determined, including: matching the first positioning information of the current contestant with a preset track path, determining the first section path type and the first section path length corresponding to the section where the first positioning information is located in the matching result; calculating the weighted sum of the first section path type and the first section path length based on a preset weight, to obtain the first section complexity corresponding to the first positioning information of the current contestant.

[0032] The first race section path type can be a track type of a track corresponding to the race section to which the first positioning information belongs. The first race section path length can be a total length of the race section to which the first positioning information belongs. The scheme is race section division according to the track type, and the track type of the track within the race section path length range is the same. The preset weight can include a first preset weight corresponding to the race section path type and a second preset weight corresponding to the race section length. The first preset weight can be a parameter representing the influence degree of the race section path type on the race section complexity. The second preset weight can be a parameter representing the influence degree of the race section length on the race section complexity.

[0033] In one embodiment, the race section position coordinate range of each race section in the preset track path can be determined in advance according to the conversion relationship between the track map coordinate system and the actual space coordinate system, the first positioning information is compared with each position coordinate in the race section position coordinate range, the race section matching the first positioning information is determined, and the path type and the path length of the track corresponding to the race section in the track map are read to obtain the first race section path type and the first race section path length. The weighted sum of the first race section path type and the first race section path length is calculated according to the preset weight to obtain the first race section complexity corresponding to the first positioning information of the current contestant.

[0034] The scheme can achieve the purpose of taking the race section length as an influencing factor of the race section complexity for race section complexity evaluation, and improve the comprehensiveness of the race section complexity calculation.

[0035] S103, generating speed real-time prompt information based on the speed range to send to the wearable device worn by the current contestant for prompting the current contestant.

[0036] In one embodiment, the speed real-time prompt information can be generated according to the speed range, and the speed real-time prompt information is sent to the wearable device worn by the current contestant for prompting the current contestant to adjust the speed. After receiving the speed real-time prompt information through the wearable device, the current contestant can adjust the speed according to the speed real-time prompt information to maintain the current ranking, or can adaptively adjust the speed according to the speed real-time prompt information as a reference to adjust the ranking at the next time, which is not limited here.

[0037] The technical scheme provided by the embodiments of the present application, in the case of speed information prompt to the current contestant, acquires the positioning information and speed data of each contestant in real time, determines the current contestant's current ranking and the target contestant with the backward adjacent ranking of the current contestant according to the positioning information, determines the first race segment complexity corresponding to the first positioning information of the current contestant and the second race segment complexity corresponding to the second positioning information of the target contestant, determines the speed range of the current contestant to keep the current ranking according to the speed data, the first race segment complexity and the second race segment complexity, and generates the speed real-time prompt information based on the speed range to send to the wearable device worn by the current contestant for prompting the current contestant. Through the above speed information real-time prompting method, the problems of inaccurate speed prompt and inability to prompt the speed information based on the real-time ranking in the prior art are solved. The current contestant's current ranking and the target contestant with the backward adjacent ranking of the current contestant are determined by acquiring the real-time positioning information of each contestant, the speed range of the current contestant to keep the current ranking is determined according to the race segment complexity and the speed data, the speed information is generated and prompted, the purpose of combining the real-time ranking of the contestant and the race segment complexity to prompt the speed information is achieved, the accuracy of the real-time speed information prompt to the contestant is improved, and the event experience is significantly improved.

[0038] Figure 2 The flowchart for determining the target contestant provided by the embodiments of the present application is shown in FIG. 1. Figure 2 As shown in FIG. 1, the specific steps include the following steps: S201, determining a plurality of candidate contestants within a preset range behind the current contestant according to the positioning information, and determining the actual path distance between each candidate contestant and the current contestant according to the path parameters of the preset race track path and the positioning information of each contestant.

[0039] The candidate contestant can be a contestant behind the current contestant and the straight-line distance between the current contestant and the contestant is less than or equal to the preset range. The path parameters can include the race segment name, race segment endpoint coordinates, race segment length and race track path direction of the preset race track path. The actual path distance can be the total distance that the candidate contestant needs to travel to reach the location of the current contestant according to the preset race track path.

[0040] In one embodiment, a semicircle can be drawn with the positioning information of the current contestant as the center and with a preset length as the radius in the opposite direction of the race direction to obtain a backward preset range of the current contestant, and a plurality of candidate contestants within the backward preset range can be determined according to the positioning information of each contestant at the current time. The current segment to which the current contestant and each candidate contestant belongs can be determined according to the segment endpoint coordinates in the path parameters of the preset race track path and the positioning information of each contestant, and the segment name and segment length between the current contestant and each candidate contestant can be determined according to the race track path direction and the current segment to which each contestant belongs. The actual path distance between each candidate contestant and the current contestant can be calculated according to the segment length and the distance between the current position of each contestant and the segment starting point.

[0041] Figure 3 is a schematic diagram of a backward preset range in a race track map provided by an embodiment of the present application. As shown in Figure 3 , the diagram includes the position of the contestant in the race track map after the positioning information of the contestant is mapped to the race track map. Among them, point A is the position of the contestant in the race track map. A semicircle is drawn with point A as the center and with a preset length R as the radius in the opposite direction of the race direction F to obtain the backward preset range of the current contestant, that is, the range enclosed by the dashed line in the diagram. The range enclosed by the dashed line includes a segment with A and B points as endpoints and a segment with C and D points as endpoints. The straight line distance between the positions of the contestants in the two segments and the position of the current contestant is less than or equal to the preset length. Therefore, the contestants whose positioning information at the current time is in the two segments are candidate contestants. As can be seen from the diagram, the straight line distance between the candidate contestant and the current contestant is not the actual path distance. Therefore, it is necessary to further calculate the actual path distance between each candidate contestant and the current contestant according to the path parameters to determine whether each candidate contestant is backward adjacent to the current contestant.

[0042] The diagram also includes a race track path, a race track starting point identifier, a race track ending point identifier, a supply station identifier, an uphill starting point identifier, an uphill ending point identifier, a downhill starting point identifier, a downhill ending point identifier, a turning point identifier, and a race track path direction. The race track information corresponding to each identifier is stored in the identifier, such as the segment name of the segment where the uphill identifier in the diagram is uphill segment, the name of the identifier is uphill segment starting point, the coordinates of the uphill segment starting point in the preset race track coordinate system are (x, y, z), the slope of the segment is M, the total length of the uphill is L, and the road flatness of the uphill stage race track is K. The terrain, length, and attribute information of each segment corresponding to the race track can be determined by reading the data stored in the identifier. The unmarked race track in the diagram is a flat road race track.

[0043] In one embodiment, the path parameters include sample point coordinates of a plurality of preset path sampling points in a preset track path coordinate system, wherein a path shape between adjacent preset path sampling points is a straight line; the actual path distance between each candidate contestant and the current contestant is determined according to the path parameters of the preset track path and the positioning information of each contestant, including: determining, according to the positioning information of each contestant, first instantaneous point coordinates of the current contestant in the preset track path coordinate system and second instantaneous point coordinates of each candidate contestant in the preset track path coordinate system; determining the first target sample point coordinates closest to the first instantaneous point coordinates, the second target sample point coordinates closest to each second instantaneous point coordinates, and the target sample point coordinates between the first target sample point coordinates and each second target sample point coordinates in the sample point coordinates; calculating the sample point path distance between the first target sample point coordinates and each second target sample point coordinates according to the target sample point coordinates; and correcting each sample point path distance according to the first deviation distance between the first instantaneous point coordinates and the first target sample point coordinates and the second deviation distance between each second instantaneous point coordinates and the second target sample point coordinates, to obtain the actual path distance between each candidate contestant and the current contestant.

[0044] In one embodiment, the path parameters include sample point coordinates of a plurality of preset path sampling points in a preset track path coordinate system, wherein a path shape between adjacent preset path sampling points is a straight line; the actual path distance between each candidate contestant and the current contestant is determined according to the path parameters of the preset track path and the positioning information of each contestant, including: determining, according to the positioning information of each contestant, first instantaneous point coordinates of the current contestant in the preset track path coordinate system and second instantaneous point coordinates of each candidate contestant in the preset track path coordinate system; determining the first target sample point coordinates closest to the first instantaneous point coordinates, the second target sample point coordinates closest to each second instantaneous point coordinates, and the target sample point coordinates between the first target sample point coordinates and each second target sample point coordinates in the sample point coordinates; calculating the sample point path distance between the first target sample point coordinates and each second target sample point coordinates according to the target sample point coordinates; and correcting each sample point path distance according to the first deviation distance between the first instantaneous point coordinates and the first target sample point coordinates and the second deviation distance between each second instantaneous point coordinates and the second target sample point coordinates, to obtain the actual path distance between each candidate contestant and the current contestant.

[0045] In one embodiment, the first instantaneous point coordinate of the current contestant in the preset track path coordinate system and the second instantaneous point coordinate of each candidate contestant in the preset track path coordinate system can be determined according to the positioning information of each contestant, the distance between each sampling point coordinate and the first instantaneous point coordinate, and the distance between each sampling point coordinate and the second instantaneous point coordinate can be calculated respectively, the first target sampling point coordinate closest to the first instantaneous point coordinate, the second target sampling point coordinate closest to each second instantaneous point coordinate, and the target sampling point coordinate between the first target sampling point coordinate and each second target sampling point coordinate can be determined. The sum of the path distances of the plurality of straight line sections between the first target sampling point coordinate and each second target sampling point coordinate is calculated according to the target sampling point coordinate, each sampling point path distance is corrected according to the first deviation distance between the first instantaneous point coordinate and the first target sampling point coordinate and the second deviation distance between each second instantaneous point coordinate and the second target sampling point coordinate, and the actual path distance between each candidate contestant and the current contestant is obtained.

[0046] According to the positioning information of each contestant, the first target sampling point coordinate closest to the current contestant and the second target sampling point coordinate closest to each second instantaneous point coordinate are determined, and the actual path distance between each candidate contestant and the current contestant is calculated according to the sampling point coordinate. The purpose of calculating the actual path distance based on the track direction and path shape is achieved, and the accuracy of the actual path distance calculation result is improved.

[0047] S202, based on the preset adjacent path distance and the actual path distance, the plurality of candidate contestants are screened to obtain the target contestant of the backward adjacent ranking of the current contestant.

[0048] The preset adjacent path distance can be the maximum path distance between the candidate contestant and the current contestant in the case of adjacent ranking of the current contestant. The preset adjacent path distance can be equal to the preset length corresponding to the above-mentioned backward preset range.

[0049] In one embodiment, the preset adjacent path distance and the actual path distance can be compared, the candidate contestant whose actual path distance is smaller than the preset adjacent path distance is filtered out, and the target contestant of the backward adjacent ranking of the current contestant is obtained.

[0050] The technical scheme provided by the embodiments of the present application can determine a plurality of candidate contestants behind the current contestant according to the positioning information, determine the actual path distance between each candidate contestant and the current contestant according to the path parameters of the preset track path and the positioning information of each contestant, and screen the plurality of candidate contestants based on the preset adjacent path distance and the actual path distance, so as to obtain the target contestant with the backward adjacent ranking of the current contestant. The problem that the determination result of the target contestant is inaccurate due to the shape of the track path can be avoided, and the plurality of target contestants adjacent to the current contestant in the backward direction can be determined through the preset adjacent path distance, thereby improving the rationality of the determination of the target contestant.

[0051] Figure 4 The flowchart for determining the speed range is provided by the embodiments of the present application. As shown in Figure 4 , the specific steps include the following steps: S401, determining a first speed adjustment ratio corresponding to the first race segment complexity and a second speed adjustment ratio corresponding to the second race segment complexity.
