[0029] Currently, the existing trajectory reporting solutions mainly report the user's location information at certain time intervals in advance and then at the time intervals during the user's travel. It is unable to intelligently determine the location coordinates that need to be reported when the outdoor terrain is not complex, thereby reducing the number of trajectory reports and reducing battery power consumption. It is difficult to meet the low-power trajectory reporting requirements under non-complex travel conditions.

[0030] In view of the above problems, an embodiment of the present application provides a low-power trajectory reporting method and device, which is described in detail below in conjunction with the accompanying drawings.

[0031] See also Figure 1 , Figure 1 is a system architecture diagram of an emergency rescue service platform provided by an embodiment of the present application, such as Figure 1As shown, the emergency rescue service platform includes a server 101 and a positioning terminal 102 , and the positioning terminal 102 includes a signal receiver 103 , a processor 104 , a communication device 105 , and the like.

Optionally, the processor 210 can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The processor 210 can integrate one or a combination of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. Among them, the CPU mainly processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications.

[0040] See also Figure 3 , Figure 3 This is a flowchart of a low-power trajectory reporting method provided by an embodiment of the present application, which is applied to Figure 1 Server 101 in, such as Figure 3 As shown, the method comprises the following steps:

[0041] Step S310: the server 101 obtains a route navigation map of the route to be traveled from the positioning terminal.

[0042] Among them, the method for the positioning terminal to obtain the route navigation map of the route to be traveled can be that a third party imports the outdoor route into the positioning terminal, or performs track navigation. When performing the track navigation, it is necessary to establish a communication connection between the positioning terminal and the Beidou box. The Beidou box is a Beidou civilian communication terminal that can send and receive Beidou short messages within any range in China. The Beidou box is used in conjunction with the Beidou box assistant APP to realize the functions of satellite SMS reporting safety and one-click SOS alarm.

[0043] The tracking navigation is divided into two steps, the first step is to record the track, and the second step is to upload the track. The recording track means that the Beidou box turns on the track recording function, records a location point information according to each fixed interval, and then converts the track data set into GPX data format, and supports Bluetooth export of tracks and location marking functions; and the track upload means that when the user needs the track, the track data in GPX format is exported from the Beidou box to the positioning terminal using Bluetooth.

[0044] In a possible embodiment, the recording track includes:

[0045] Determine whether the user long presses or short presses the track recording key;

[0046] If it is detected that the user long presses the track recording key, the track recording function is turned on;

[0047] The positioning icon in the status bar flashes, the Beidou positioning module starts real-time positioning, and the screen displays "Positioning";

[0048] Determine whether the first positioning is successful after one minute;

[0049] If it fails, a prompt "locate in an open area" is displayed; and if it succeeds, the positioning icon in the status bar is always on, and the screen displays an animation of the trajectory being recorded;

[0050] If it is detected that the user short presses the track record key, the current location is marked as a special place; and after selecting the marked location type through the switch key, the track record key is short pressed again, and the marking is successful.

[0051] Among them, the screen displays the trajectory recording animation, including: the Beidou box records the position in real time according to the preset trajectory recording frequency, and uses an algorithm to filter the position points, and finally records the trajectory data in GPX data format.

[0052] In a possible embodiment, the trajectory uploading includes:

[0053] Determine whether the positioning terminal and Beidou box are connected;

[0054] If yes, click the track export button, which is used to control the positioning terminal to send the required track request and the time limit of a certain day or a certain time period to the Beidou box;

[0055] After receiving the request, the Beidou box replies with GPX track data that meets the conditions;

[0056] After the positioning terminal receives the track data, the user interface UI displays a track list, provides track data download and forwarding functions, and supports track name modification.

[0057] After the positioning terminal receives the trajectory data, a route navigation map of the route to be traveled is formed according to the trajectory data. When the user needs to obtain the route navigation map of the route to be traveled, the user can send a first request instruction to the positioning terminal through the server to obtain the route navigation map from the positioning terminal, and the first request instruction is used to instruct the positioning terminal to send the route navigation map to the server.

[0058] The positioning terminal may be a smart phone, a smart watch, a smart bracelet, a smart positioning backpack, etc.

[0059] It can be seen that in this embodiment, the positioning terminal imports a route map through a third party or performs track navigation to obtain a route navigation map of the user's upcoming travel route, so that the server can obtain the route navigation map of the route to be traveled from the positioning terminal, and then further process the road section information to obtain a trajectory reporting strategy, and implement more intelligent and flexible trajectory reporting based on the trajectory reporting strategy, which is conducive to reducing power consumption.

[0060] Step S320, obtaining a plurality of turning point coordinates in the route to be traveled according to the route navigation map, wherein a single turning point coordinate is used to represent the position coordinate of a correct intersection in a single fork in the road located on the route to be traveled.

[0061] Exemplarily, the server first determines multiple forks in the route to be traveled based on the route navigation map, each of the multiple forks includes at least one intersection; then, for each fork, the server determines the correct intersection among the at least one intersection whose driving direction is consistent with the direction of the route to be traveled; then, the server obtains the position coordinates of the correct intersection, and uses the position coordinates of the correct intersection as the turning point coordinates.

[0062] In a possible embodiment, the obtaining of the position coordinates of the correct intersection may be calculating the position coordinates of the correct intersection in historical travel events, specifically including:

[0063] The positioning terminal sends a positioning request to the Beidou server;

[0064] The Beidou server receives the positioning request and sends the positioning request to the Beidou near-earth satellite;

[0065] The Beidou near-earth satellite receives the positioning request, and sends a signal to the positioning terminal according to the positioning request, wherein the signal includes satellite position information and time information;

[0066] The positioning terminal receives the signals from multiple satellites;

[0067] The positioning terminal determines the location of the positioning terminal according to the satellite position information and the time information.

[0068] The positioning terminal determines the location of the positioning terminal according to the satellite position information and the time information, including: the positioning terminal determines the propagation time of the signal by measuring the time from the satellite transmitting the signal to the receiver receiving the signal; and by receiving signals from at least three satellites, the positioning terminal can determine the distance between itself and each satellite; finally, the location of the positioning terminal is calculated using the triangulation principle.

[0069] For example, the three satellites are satellite A, satellite B, and satellite C, and the distances between the three satellites and the positioning terminal are R1, R2, and R3, respectively. Then, the surface of a sphere with the position of satellite A as the center and R1 as the radius can be determined. According to this method, the surfaces of two other spheres with B and C as the centers can be obtained. The location of the positioning terminal is at the intersection of the three spheres. In the historical travel event, when the positioning terminal is located at the correct intersection, the location coordinates of the correct intersection are obtained according to this method.

[0070] It can be seen that in this embodiment, after obtaining the route navigation map, the positioning terminal can determine the coordinates of multiple turning points in the route to be traveled in combination with historical travel data, which is conducive to dividing the route to be traveled into multiple sub-sections to be traveled according to the turning point coordinates and determining the trajectory reporting strategy according to the number of turning point coordinates and the trajectory reporting frequency, thereby realizing flexible determination of the trajectory reporting strategy and reducing the battery consumption of the positioning terminal.

[0071] Step S330: dividing the route to be traveled into a plurality of sub-segments to be traveled according to the plurality of turning point coordinates.

[0072] In a possible embodiment, dividing the route to be traveled into a plurality of sub-segments to be traveled according to the plurality of inflection point coordinates includes:

[0073] Determine a plurality of target inflection point coordinates according to the plurality of inflection point coordinates, wherein there are a plurality of the inflection point coordinates whose number is a second preset value between adjacent target inflection point coordinates;

[0074] Marking the to-be-traveled route according to the target turning point coordinates to obtain a plurality of marking positions;

[0075] The route to be traveled is divided into the plurality of sub-segments to be traveled according to the marked positions.

[0076] Exemplarily, the route to be traveled includes 13 turning point coordinates, and the 13 turning point coordinates include the coordinates of the starting position and the coordinates of the end position. The second preset value is 2, then the first target turning point coordinate is the starting point coordinate 1, the second target turning point coordinate is the turning point coordinate 4, the third target turning point coordinate is the turning point coordinate 7, the fourth target turning point coordinate is the turning point coordinate 10, and the fifth target turning point coordinate is the end point coordinate 13. There are two turning point coordinates whose number is the second preset value 2 between every two of the target turning point coordinates.

[0077] After determining the coordinates of the five target turning points, the travel route to be traveled is marked at the coordinates of the target turning points to obtain five marking positions, and then the travel route to be traveled is segmented at the five marking positions to be divided into four sub-segments to be traveled.

[0078] It can be seen that in this embodiment, after obtaining the turning point coordinates in the route to be traveled, the server divides the route to be traveled into multiple sub-segments to be traveled according to a certain number of turning point coordinates, which is conducive to executing multiple processing steps in each sub-segment to be traveled to determine the trajectory reporting strategy, which is conducive to improving the server processing efficiency and quickly determining the trajectory reporting strategy.

[0079] Step S340, performing the following processing for the multiple sub-segments to be traveled to obtain a trajectory reporting strategy: determining the sub-segment time required for the user to pass through each sub-segment to be traveled based on the length of each sub-segment to be traveled, the ascent height, and the user's historical movement data; and determining the number of trajectory reports based on the sub-segment time and the trajectory reporting frequency; and determining the trajectory reporting strategy based on the relationship between the number of trajectory reports and the number of inflection point coordinates.

[0080] In a possible embodiment, determining the sub-segment time required for the user to pass through each sub-segment to be traveled according to the length and the ascending height of each sub-segment to be traveled and the historical movement data of the user includes:

[0081] Acquire a plurality of historical motion data of the user in different motion modes, the motion modes including mountaineering, cycling, hiking and running, the historical motion data being used to characterize historical motion parameters of the user in the same motion mode, the historical motion parameters including motion duration, total length, cumulative climbing height and altitude;

[0082] Determine, according to the plurality of historical motion data, a plurality of association relationships between the historical motion parameters and the motion duration in the different motion modes;

[0083] Determine the sub-motion mode of the user in each of the to-be-traveled sub-segments;

[0084] Determine a sub-association relationship corresponding to the sub-motion pattern among the multiple association relationships;

[0085] The sub-section time is determined according to the sub-association relationship.

[0086] In a possible embodiment, the multiple association relationships between the historical motion parameters and the motion time are represented by multiple multivariate linear regression models, and there is a one-to-one correspondence between the multiple association relationships and the multiple multivariate linear regression models; determining the sub-section time according to the sub-association relationship includes:

[0087] Determine a target multiple linear regression model corresponding to the sub-association relationship;

[0088] Substitute the length of each sub-section to be traveled and the ascending height into the target multivariate linear regression model to obtain the sub-section time.

[0089] For example, the historical exercise mode of the user is mountain climbing, and the historical exercise parameters under the corresponding mode include exercise time, total length, cumulative climbing height and altitude. The user's five mountain climbing data can be as follows:

[0090] Activity Exercise time Overall length Cumulative climb height highest sea 1 120 8.5 600 1500 2 90 6.2 400 1200 3 150 12.1 800 1800 4 100 7.8 500 1300 5 110 9.3 550 1400

[0091] Mountaineering data sheet

[0092] For example, x1 can be used to represent the total length, x2 can be used to represent the cumulative climbing height, x3 can be used to represent the maximum altitude, and y can be used to represent the exercise time. Then, the linear regression model in the mountain climbing mode can be obtained as follows:

[0093] y=β0+β1x1+β2x2+β3x3;

[0094] Among them, according to the calculation formula and the climbing data in the climbing data table, the regression coefficients β0, β1, β2 and β3 can be calculated. Specifically, the average values ​​of x1, x2, x3 and y are first calculated, and then the deviation product is calculated, and β1, β2 and β3 are obtained based on the deviation product; finally, the intercept is calculated to obtain β0.

[0095] The average value formula includes formula (1), formula (2), formula (3) and formula (4), and the formula is:

[0096]

[0097] Wherein, the deviation product is calculated according to the average value through formula (5), formula (6), formula (7), formula (8), formula (9) and formula (10), and the formula is:

[0098]

[0099] According to the deviation product, β1, β2 and β3 can be obtained by the following formula:

[0100]

[0101] Furthermore, the formula for calculating the intercept β0 according to β1, β2 and β3 is:

[0102]

[0103] According to the above formula and calculation results, the corresponding multivariate linear regression equation under the mountain climbing mode can be obtained as follows:

[0104] Exercise time = -111 + 4.52 × total length + 0.59 × cumulative climbing height + 0.59 × maximum altitude.

[0105] Among them, the influence of other motion parameters on the motion time in each motion mode can be obtained according to the historical motion data and historical motion mode, which is mainly expressed by a multiple linear regression equation. The server will pre-store multiple multiple linear regression equations. When the server detects the motion mode of the user in each sub-segment to be traveled, the multiple linear regression method in the corresponding mode is called, and the motion parameters corresponding to the motion mode are input into the multiple linear regression equation, so as to obtain the sub-segment time of the current segment.

[0106] In a possible embodiment, determining the number of trajectory reporting times according to the sub-section time and the trajectory reporting frequency includes: summing up the times of multiple sub-sections to obtain a total time; and summing up the total time and the trajectory reporting frequency to obtain the number of trajectory reporting times.

[0107] In a possible embodiment, determining the trajectory reporting strategy according to the magnitude relationship between the number of trajectory reports and the number of inflection point coordinates includes:

[0108] If the number of trajectory reports is greater than the number of inflection point coordinates, determining the trajectory reporting strategy to report to the server according to the inflection point coordinates, and determining the inflection point coordinates as the reporting coordinates;

[0109] If the number of trajectory reports is less than the number of turning point coordinates, the trajectory reporting strategy is determined to be reporting to the server according to the trajectory reporting strategy, and the position coordinates corresponding to the trajectory reporting frequency in the to-be-traveled route are determined as the reporting coordinates.

[0110] In a possible embodiment, determining the position coordinates corresponding to the trajectory reporting frequency in the to-be-traveled route as the reporting coordinates includes:

[0111] Recording the user's movement time on the route to be traveled in real time, with the user's movement time at the starting position of the route to be traveled being the starting time;

[0112] Determine the interval duration for performing the trajectory reporting according to the trajectory reporting frequency;

[0113] Marking the location of the user according to the starting time and the interval duration to obtain multiple reported locations;

[0114] Obtaining coordinates of the reported location;

[0115] The coordinates of the reported position are determined as the reported coordinates.

[0116] Exemplarily, the starting time is 0 minutes, the trajectory reporting frequency is 0.2 times / minute, and the interval between every two trajectory reports is 5 minutes. The number of trajectory reports can be 6 times, then the user's position is marked at 0 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes respectively, and 6 reported positions are obtained. Then the server obtains the coordinates of the reported position and determines the coordinates of the reported position as the reported coordinates.

[0117] Wherein, obtaining the coordinates of the reported position includes sending a second instruction to the positioning terminal, wherein the second instruction is used to instruct the positioning terminal to obtain the coordinates of the reported position and send the coordinates of the reported position to the server; the server receives the coordinates of the reported position.

[0118] It can be seen that in this embodiment, the server processes multiple sub-sections to be traveled. First, the sub-section time required for the user to pass through each sub-section to be traveled is determined according to the length of each sub-section to be traveled, the ascent height and the historical movement data of the user; then, the number of trajectory reports is determined according to the sub-section time and the trajectory reporting frequency; finally, the trajectory reporting strategy is determined according to the relationship between the number of trajectory reports and the number of turning point coordinates, so as to achieve the goal of reducing the number of trajectory reports as much as possible on the basis of satisfying trajectory positioning under simple road conditions, which is conducive to reducing energy loss.

[0119] Step S350, sending a first instruction to the positioning terminal to obtain positioning information; and reporting the positioning information to the emergency rescue service platform to complete the trajectory reporting task of this travel event, wherein the first instruction is used to instruct the positioning terminal to send the positioning information to the server according to the trajectory reporting strategy.

[0120] In a possible embodiment, before sending the first instruction to the positioning terminal to obtain the positioning information, it is detected that the power of the positioning terminal is lower than a preset threshold; sending the first instruction to the positioning terminal to obtain the positioning information includes:

[0121] The positioning terminal receives the first instruction;

[0122] The positioning terminal acquires the positioning information of the reported coordinates according to the trajectory reporting strategy, where the positioning information includes the position information of the reported coordinates and other positioning information;

[0123] The positioning terminal divides the reported coordinates into a plurality of reported coordinate groups, each of the plurality of reported coordinate groups including a first preset value of reported coordinates;

[0124] The positioning terminal sends the multiple reported coordinate groups to the server in sequence;

[0125] The server receives the multiple reported coordinate groups, and obtains positioning information of multiple reported coordinates in the multiple reported coordinate groups.

[0126] The positioning coordinate location information is expressed in latitude and longitude coordinates, and the other positioning information includes the altitude, speed, direction, timestamp, signal strength, horizontal accuracy and vertical accuracy, location source, etc. of the location of the positioning coordinate. The location source refers to the source of the positioning information, including GPS, WIFI, and cellular network, etc.

[0127] Exemplarily, there are 25 reported coordinates, and the first preset value is 5, then the reported coordinates are divided into 5 reported coordinate groups, each reported coordinate group contains 5 reported coordinates, and the positioning terminal sends the 5 reported coordinate groups and the positioning information corresponding to the reported coordinates to the server in turn. The server receives the reported coordinate groups and obtains the corresponding positioning information.

[0128] It can be seen that in this embodiment, the server sends a first instruction to the positioning terminal, instructing the positioning terminal to obtain the positioning information of the reported coordinates according to the trajectory reporting strategy, and sends the positioning information to the server, thereby obtaining the positioning information of the reported coordinates, and then sending the positioning information to the emergency rescue service platform, thereby achieving the goal of reducing the number of trajectory reports as much as possible on the basis of satisfying the motion trajectory under simple road conditions, which is beneficial to reducing the power consumption of the positioning terminal.

[0129] See also Figure 4 , Figure 4 is an example diagram of a travel route provided in an embodiment of the present application, such as Figure 4 As shown, the travel route includes 25 turning point coordinates.

[0130] There are 25 turning points from the starting point of the route to be traveled to the end point of the route to be traveled, and the turning points are numbered from 1 to 25. Each turning point corresponds to a turning point coordinate, and a single turning point coordinate is used to represent the position coordinate of the correct intersection on the route to be traveled in a single fork.

[0131] Exemplarily, the server first determines multiple forks in the route to be traveled based on the route navigation map, each of the multiple forks includes at least one intersection; then, for each fork, the server determines the correct intersection among the at least one intersection whose driving direction is consistent with the direction of the route to be traveled; then, the server obtains the position coordinates of the correct intersection, and uses the position coordinates of the correct intersection as the turning point coordinates.

[0132] In a possible embodiment, the obtaining of the position coordinates of the correct intersection may be calculating the position coordinates of the correct intersection in historical travel events, specifically including:

[0133] The positioning terminal sends a positioning request to the Beidou server;

[0134] The Beidou server receives the positioning request and sends the positioning request to the Beidou near-earth satellite;

[0135] The Beidou near-earth satellite receives the positioning request, and sends a signal to the positioning terminal according to the positioning request, wherein the signal includes satellite position information and time information;

[0136] The positioning terminal receives the signals from multiple satellites;

[0137] The positioning terminal determines the location of the positioning terminal according to the satellite position information and the time information.

[0138] The positioning terminal determines the location of the positioning terminal according to the satellite position information and the time information, including: the positioning terminal determines the propagation time of the signal by measuring the time from the satellite transmitting the signal to the receiver receiving the signal; and by receiving signals from at least three satellites, the positioning terminal can determine the distance between itself and each satellite; finally, the location of the positioning terminal is calculated using the triangulation principle.

[0139] It can be seen that in this embodiment, the server obtains the coordinates of 25 turning points in the route to be traveled, and divides the route to be traveled into multiple sub-sections to be traveled according to a certain number of turning point coordinates; then the multiple sub-sections to be traveled are processed to obtain the number of trajectory reports. If the number of trajectory reports is greater than 25, the trajectory reporting strategy is determined to be reported according to the turning point coordinates. If not, the trajectory reporting strategy is determined to be reported according to the trajectory reporting frequency, thereby realizing the flexible determination of the trajectory reporting strategy under simple road conditions, reducing the number of trajectory reports as much as possible when the trajectory is present, and reducing the power consumption of the positioning terminal.

The server will pre-store multiple multiple linear regression equations. When the server detects the motion mode of the user in each sub-segment to be traveled, the multiple linear regression method in the corresponding mode is called, and the motion parameters corresponding to the motion mode are input into the multiple linear regression equation, so as to obtain the sub-segment time of the current segment.
