[0021] Please refer to Figure 1 , Figure 1 : is a flow chart of a method for displaying a motion trajectory based on Beidou positioning in some embodiments of the present application. The method for displaying a motion trajectory based on Beidou positioning is used in a terminal device, such as a computer, a mobile phone, etc. The method for displaying a motion trajectory based on Beidou positioning comprises the following steps: S11, obtaining positioning information received by the smart wearable device, including real-time positioning location data and positioning time data; S12, obtaining effective positioning time data according to the positioning time data processing, and obtaining corresponding effective real-time positioning position data according to the effective positioning time data; S13, obtaining positioning position deviation data according to the effective real-time positioning position data, and comparing the positioning position deviation data with a preset positioning position deviation threshold to obtain a positioning difference state; S14, obtaining positioning parameters according to the positioning difference state, obtaining a positioning validity index according to the positioning parameters, and obtaining valid positioning position data after comparing the positioning validity index; S15, obtaining real-time motion state data of the smart wearable device, and combining the real-time motion state data with the effective positioning position data through a preset fusion position processing model to obtain fusion position data; S16: marking the fused position data in a preset smart wearable device motion coordinate system, connecting the fused position data to obtain a motion trajectory, and sending the motion trajectory to a display of the smart wearable device for display.

[0022] It should be noted that the display of the motion trajectory of the smart wearable device is realized based on the acquired positioning information. Therefore, there will be a positioning device in the smart device. In this embodiment, in order to improve the accuracy of positioning, two different positioning systems will be built-in, such as Beidou positioning and GPS positioning; the real-time positioning position data and positioning time data received by the smart wearable device are one-to-one corresponding, and can be obtained according to the time interval period set by the user or the device. In the process of the smart wearable device obtaining positioning information, the positioning time may not be updated in time, resulting in inaccurate positioning data, but if the two positioning systems are running at the same time, the occurrence of this situation can be greatly reduced; after determining that the valid positioning time data is obtained, it can be To obtain the effective real-time positioning position data corresponding to the time. If one positioning system is effective, a valid real-time positioning position can be obtained, and there is no positioning position deviation in this state; if the two positioning systems are effective at the same time, the positioning difference state can be obtained after threshold comparison based on the positioning position deviation data, and the positioning parameters can be obtained based on the difference state, and the positioning validity index can be obtained based on the positioning parameters, and the effective positioning position data can be obtained based on the positioning validity index; the real-time motion state data is processed through a preset fusion position processing model to obtain the fused position data, and finally the fused position data is marked in the motion coordinate system of the smart wearable device, the motion trajectory data is obtained, and displayed on the display of the smart wearable device.

[0023] Please refer to Figure 2 , Figure 2The present invention provides a flowchart of a method for displaying a motion trajectory based on Beidou positioning to obtain positioning position data and positioning time data. According to an embodiment of the present invention, the method of obtaining positioning information received by a smart wearable device, including positioning position data and positioning time data, specifically includes: S21, obtaining positioning position data at a preset time interval, including first real-time positioning position data and second real-time positioning position data; S22, the first real-time positioning position data includes first longitude data, first latitude data and first altitude data, and the second real-time positioning position data includes second longitude data, second latitude data and second altitude data; S23, obtaining positioning time data, including theoretical receiving time data and real-time receiving time data; S24. The real-time receiving time data includes first real-time receiving time data corresponding to the first real-time positioning position data and second real-time receiving time data corresponding to the second real-time positioning position data.

[0024] It should be noted that the positioning device in the smart wearable device will continuously obtain positioning location data at fixed time intervals. In this embodiment, two positioning location data can be obtained at the same time, so they are marked as first real-time positioning location data and second real-time positioning location data. The first real-time positioning location data and the second real-time positioning location data have corresponding longitude data, latitude data and altitude data; after the smart wearable device sets the fixed time interval, there will be a theoretical time for receiving the positioning information, and there will also be a corresponding real-time reception time during actual reception.

[0025] Please refer to Figure 3 , Figure 3 The present invention provides a flowchart of a method for displaying a motion trajectory based on Beidou positioning to obtain effective real-time positioning position data. According to an embodiment of the present invention, the processing of the positioning time data to obtain effective positioning time data and obtaining corresponding effective real-time positioning position data according to the effective positioning time data specifically include: S31, subtracting the theoretical receiving time data from the first real-time receiving time data, and then dividing the data by the preset time delay standard data to obtain a first delay time relative index; S32, subtracting the theoretical receiving time data from the second real-time receiving time data, and then dividing the result by the preset time delay standard data to obtain a second delay time relative index; S33, comparing the first delay time relative index and the second delay time relative index with a preset delay time relative index threshold, to obtain real-time positioning time status data, including valid positioning time data or invalid positioning time data; S34. Acquire real-time positioning location data corresponding to the effective positioning time data, and record it as effective real-time positioning location data.

[0026] It should be noted that if the real-time receiving time is later than the theoretical receiving time by a certain value, it means that there is a delay in the time of receiving the signal, and the positioning position data is not updated in time. After subtracting the theoretical receiving time data from the real-time receiving time data, the difference is divided by the preset time delay standard data to obtain the delay time relative index. According to this logic, the first delay time relative index and the second delay time relative index are obtained respectively. In the calculation process of subtracting the theoretical receiving time data from the real-time receiving time data, the real-time receiving time data refers to the time that is later than or equal to the theoretical receiving time data and is closest to the theoretical receiving time data. The first delay time relative index and the second delay time relative index are compared with the preset delay time relative index thresholds respectively to obtain the real-time receiving time data. The positioning time status data includes valid positioning time data or invalid positioning time data; if the first delay time relative index is less than the delay time relative index threshold, the corresponding positioning time data is valid positioning time data; if the first delay time relative index is greater than or equal to the delay time relative index threshold, the corresponding positioning time data is invalid positioning time data; if the second delay time relative index is less than the delay time relative index threshold, the corresponding positioning time data is valid positioning time data; if the second delay time relative index is greater than or equal to the delay time relative index threshold, the corresponding positioning time data is invalid positioning time data, and the valid real-time positioning position data includes the corresponding valid longitude data, valid latitude data and valid altitude data.

[0027] Please refer to Figure 4 , Figure 4 This is a flowchart of obtaining a positioning difference state of a motion trajectory display method based on Beidou positioning provided by an embodiment of the present application. According to an embodiment of the present invention, obtaining positioning position deviation data according to effective real-time positioning position data processing, and comparing the positioning position deviation data with a preset positioning position deviation threshold to obtain a positioning difference state specifically includes: S41, if the first real-time receiving time data and the second real-time receiving time data are both valid positioning time data, inputting the valid first longitude data, the valid first latitude data, the valid first altitude data, the valid second longitude data, the valid second latitude data and the valid second altitude data into a preset positioning position deviation evaluation model for processing to obtain positioning position deviation data; S42: Compare the positioning position deviation data with a preset positioning position deviation threshold to obtain a positioning difference state, including a consistent state or an inconsistent state.

[0028] It should be noted that if one of the real-time receiving time data is valid positioning time data, the valid real-time positioning position data corresponding to the valid positioning time data is unique, and the valid real-time positioning position data is directly marked as valid positioning position data; the calculation formula of the positioning position deviation data in the positioning position deviation evaluation model is: ; in, To locate the position deviation data, , , They are respectively the effective first longitude data, the effective first latitude data, and the effective first altitude data, , , They are respectively the effective second longitude data, the effective second latitude data, and the effective second altitude data, , , They are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset motion trajectory display platform based on Beidou positioning); If all the real-time received time data are invalid positioning time data, the valid real-time positioning position data of the previous fixed time interval period will be marked as valid positioning position data.

[0029] According to an embodiment of the present invention, acquiring positioning parameters according to the positioning difference state, obtaining a positioning validity index according to the positioning parameters, and obtaining valid positioning position data after comparing the positioning validity index specifically include: If the positioning difference state is a consistent state, then averaging the valid first longitude data and the valid second longitude data to obtain mean longitude data, averaging the valid first latitude data and the valid second latitude data to obtain mean latitude data, and averaging the valid first altitude data and the valid second altitude data to obtain mean altitude data; The mean longitude data, the mean latitude data and the mean altitude data are used as effective positioning location data; If the positioning difference state is an inconsistent state, obtaining positioning parameters, including first signal strength data, first number of satellites and first signal stability data corresponding to the valid first real-time positioning position data, and second signal strength data, second number of satellites and second signal stability data corresponding to the valid second real-time positioning position data; Processing the first signal strength data, the first number of satellites and the first signal stability data through a preset positioning effectiveness evaluation model to obtain a first positioning effectiveness index; Processing the second signal strength data, the second number of satellites, and the second signal stability data through a preset positioning effectiveness evaluation model to obtain a second positioning effectiveness index; The first positioning validity index and the second positioning validity index are compared to obtain valid positioning position data.

[0030] It should be noted that, in this embodiment, if the positioning difference state is an inconsistent state, it means that the position data of the two positionings differ greatly, and it is necessary to determine which valid real-time positioning position data is more accurate. There are two valid real-time positioning position data, including valid first real-time positioning position data and valid second real-time positioning position data; the positioning parameters are corresponding parameters when the smart wearable device obtains the positioning position data, including signal strength data, number of satellites and signal stability data; the first signal strength data, the first number of satellites and the first signal stability data corresponding to the first positioning information are obtained, and the second signal strength data, the second number of satellites and the second signal stability data corresponding to the second positioning information are obtained; The calculation formula of the first positioning effectiveness index is: ; in, is the first positioning effective index, , , are respectively first signal strength data, first satellite number and first signal stability data, , , They are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset motion trajectory display platform based on Beidou positioning); The calculation formula of the second positioning effectiveness index is: ; in, is the second positioning effective index, , , They are respectively the second signal strength data, the second satellite number and the second signal stability data, , , They are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset motion trajectory display platform based on Beidou positioning); The first positioning validity index and the second positioning validity index are compared, and the larger one is used as the valid positioning position data.

[0031] According to an embodiment of the present invention, the real-time motion state data of the smart wearable device is obtained, and the real-time motion state data is combined with the effective positioning position data to obtain the fused position data through a preset fused position processing model, specifically including: Obtain real-time motion status data of smart wearable devices, including acceleration data, angular velocity data and direction data; The acceleration data, angular velocity data and direction data are combined with the effective positioning position data and processed through a preset position fusion processing model to obtain fused position data.

[0032] It should be noted that the smart wearable device is a process of motion, which involves acceleration data, angular velocity data and direction data. A smooth and accurate motion trajectory cannot be obtained based solely on positioning information, and individual signals may be lost in the middle. Therefore, it is necessary to obtain fused position data based on the acceleration data, angular velocity data, direction data and effective positioning position data through a preset position fusion processing model. The position fusion processing model is a computational model obtained through training with a large amount of historical data.

[0033] It is worth mentioning that it also includes: Obtain the planned motion trajectory data for the user's preset time period; Comparing the degree of overlap between the planned motion trajectory data and the real-time motion trajectory data to obtain a degree of overlap index; Comparing the overlap index with a preset route status evaluation threshold to obtain a motion trajectory status; Extracting a first threshold and a second threshold according to the preset route status evaluation threshold, wherein the first threshold is greater than the second threshold; comparing the overlap index with a first threshold and a second threshold; If the overlap index is greater than a first threshold, the motion trajectory state is a normal state; If the overlap index is greater than the second threshold and less than or equal to the first threshold, the motion trajectory state is abnormal, and the smart wearable device issues an abnormal reminder; If the overlap index is less than or equal to the second threshold, the motion trajectory state is a warning state, the smart wearable device issues a warning and simultaneously initiates a voice call with the management user.

[0034] It should be noted that smart wearable devices are widely used among teenagers. Parents can set the movement trajectory of students during the school hours, such as the movement trajectory of walking from school to home. When the student's overlap index is high, it means that the student is walking according to the established trajectory. In this embodiment, the route state evaluation threshold is set to: (0.85, 1], the movement trajectory state is normal; (0.6, 0.85], the movement trajectory state is abnormal; [0, 0.6], the movement trajectory state is warning state; when the calculated overlap index is 0.9, the movement trajectory state is normal.

[0035] It is worth mentioning that it also includes: Obtaining the motion parameters and standard parameters of different preset stages under the user's motion trajectory, the motion parameters include average heart rate data, average cadence data and average speed data, and the standard parameters include standard heart rate data, standard cadence data and standard speed data; Inputting the average heart rate data, average cadence data, average speed data, standard heart rate data, standard cadence data and standard speed data into a preset physical condition assessment model for processing to obtain a physical condition index; Comparing the physical condition index with a preset physical condition assessment threshold to obtain a physical condition; Extracting a third threshold and a fourth threshold according to the preset physical condition assessment threshold, wherein the third threshold is greater than the fourth threshold; comparing the physical condition index with a third threshold and a fourth threshold; If the physical condition index is greater than a third threshold, the physical condition is excellent; If the physical condition index is greater than the fourth threshold and less than or equal to the third threshold, the physical condition is in good condition; If the physical condition index is less than or equal to the fourth threshold, the physical condition is in a poor state.

[0036] It should be noted that during exercise, sometimes one wants to understand the correlation between the activity status and the physical condition under the trajectory or a segment of the trajectory, that is, to understand through the physical condition index. The smaller the physical condition index, the closer it is to the standard and the more in line with the standard physical condition. During exercise, within a certain range, a person's heart rate will increase with the increase of exercise frequency and the increase of exercise speed. The physical condition assessment model is a model obtained by training with a large amount of historical data, and the physical condition index can be calculated through the model. In this embodiment, the physical condition assessment threshold is set and updated according to the updated data in the historical exercise database obtained. The user's physical condition can be displayed in stages in the exercise trajectory to facilitate the user to understand his or her own physical condition.

[0037] The present invention also discloses a motion trajectory display system based on Beidou positioning, comprising a memory and a processor, wherein the memory stores a motion trajectory display method program based on Beidou positioning, and when the motion trajectory display method program based on Beidou positioning is executed by the processor, the following steps are implemented: Obtain positioning information received by smart wearable devices, including real-time positioning location data and positioning time data; Obtain effective positioning time data according to the positioning time data processing, and obtain corresponding effective real-time positioning position data according to the effective positioning time data; The positioning position deviation data is obtained according to the effective real-time positioning position data processing, and the positioning position deviation data is compared with the preset positioning position deviation threshold to obtain the positioning difference state; Acquire positioning parameters according to the positioning difference state, obtain positioning validity index according to the positioning parameters, and obtain valid positioning position data after comparing the positioning validity index; Acquire real-time motion state data of the smart wearable device, and combine the real-time motion state data with effective positioning position data through a preset fusion position processing model to obtain fusion position data; The fused position data are marked in a preset smart wearable device motion coordinate system, and the motion trajectory is obtained after the fused position data are connected, and the motion trajectory is sent to the display of the smart wearable device for display.

[0038] It should be noted that the display of the motion trajectory of the smart wearable device is realized based on the acquired positioning information. Therefore, there will be a positioning device in the smart device. In this embodiment, in order to improve the accuracy of positioning, two different positioning systems will be built-in, such as Beidou positioning and GPS positioning; the real-time positioning position data and positioning time data received by the smart wearable device are one-to-one corresponding, and can be obtained according to the time interval period set by the user or the device. In the process of the smart wearable device obtaining positioning information, the positioning time may not be updated in time, resulting in inaccurate positioning data, but if the two positioning systems are running at the same time, the occurrence of this situation can be greatly reduced; after determining that the valid positioning time data is obtained, it can be To obtain the effective real-time positioning position data corresponding to the time. If one positioning system is effective, a valid real-time positioning position can be obtained, and there is no positioning position deviation in this state; if the two positioning systems are effective at the same time, the positioning difference state can be obtained after threshold comparison based on the positioning position deviation data, and the positioning parameters can be obtained based on the difference state, and the positioning validity index can be obtained based on the positioning parameters, and the effective positioning position data can be obtained based on the positioning validity index; the real-time motion state data is processed through a preset fusion position processing model to obtain the fused position data, and finally the fused position data is marked in the motion coordinate system of the smart wearable device, the motion trajectory data is obtained, and displayed on the display of the smart wearable device.

[0039] According to an embodiment of the present invention, the obtaining of positioning information received by the smart wearable device, including positioning position data and positioning time data, specifically includes: Acquire positioning position data at a preset time interval, including first real-time positioning position data and second real-time positioning position data; The first real-time positioning position data includes first longitude data, first latitude data and first altitude data, and the second real-time positioning position data includes second longitude data, second latitude data and second altitude data; Obtain positioning time data, including theoretical receiving time data and real-time receiving time data; The real-time receiving time data includes first real-time receiving time data corresponding to the first real-time positioning position data and second real-time receiving time data corresponding to the second real-time positioning position data.

[0040] It should be noted that the positioning device in the smart wearable device will continuously obtain positioning location data at fixed time intervals. In this embodiment, two positioning location data can be obtained at the same time, so they are marked as first real-time positioning location data and second real-time positioning location data. The first real-time positioning location data and the second real-time positioning location data have corresponding longitude data, latitude data and altitude data; after the smart wearable device sets the fixed time interval, there will be a theoretical time for receiving the positioning information, and there will also be a corresponding real-time reception time during actual reception.

[0041] According to an embodiment of the present invention, obtaining effective positioning time data according to the positioning time data processing, and obtaining corresponding effective real-time positioning position data according to the effective positioning time data specifically includes: Subtract the theoretical receiving time data from the first real-time receiving time data, and then divide the data by the preset time delay standard data to obtain a first delay time relative index; Subtract the theoretical receiving time data from the second real-time receiving time data, and then divide the data by the preset time delay standard data to obtain a second delay time relative index; Compare the first delay time relative index and the second delay time relative index with a preset delay time relative index threshold value respectively to obtain real-time positioning time state data, including valid positioning time data or invalid positioning time data; The real-time positioning position data corresponding to the effective positioning time data is obtained and recorded as the effective real-time positioning position data.

[0042] It should be noted that if the real-time receiving time is later than the theoretical receiving time by a certain value, it means that there is a delay in the time of receiving the signal, and the positioning position data is not updated in time. After subtracting the theoretical receiving time data from the real-time receiving time data, the difference is divided by the preset time delay standard data to obtain the delay time relative index. According to this logic, the first delay time relative index and the second delay time relative index are obtained respectively. In the calculation process of subtracting the theoretical receiving time data from the real-time receiving time data, the real-time receiving time data refers to the time that is later than or equal to the theoretical receiving time data and is closest to the theoretical receiving time data. The first delay time relative index and the second delay time relative index are compared with the preset delay time relative index thresholds respectively to obtain the real-time receiving time data. The positioning time status data includes valid positioning time data or invalid positioning time data; if the first delay time relative index is less than the delay time relative index threshold, the corresponding positioning time data is valid positioning time data; if the first delay time relative index is greater than or equal to the delay time relative index threshold, the corresponding positioning time data is invalid positioning time data; if the second delay time relative index is less than the delay time relative index threshold, the corresponding positioning time data is valid positioning time data; if the second delay time relative index is greater than or equal to the delay time relative index threshold, the corresponding positioning time data is invalid positioning time data, and the valid real-time positioning position data includes the corresponding valid longitude data, valid latitude data and valid altitude data.

[0043] According to an embodiment of the present invention, the processing of obtaining positioning position deviation data according to the effective real-time positioning position data, and comparing the positioning position deviation data with a preset positioning position deviation threshold to obtain a positioning difference state specifically includes: If the first real-time receiving time data and the second real-time receiving time data are both valid positioning time data, inputting the valid first longitude data, the valid first latitude data, the valid first altitude data, the valid second longitude data, the valid second latitude data and the valid second altitude data into a preset positioning position deviation evaluation model for processing to obtain positioning position deviation data; The positioning position deviation data is compared with a preset positioning position deviation threshold to obtain a positioning difference state, including a consistent state or an inconsistent state.

[0044] It should be noted that if one of the real-time receiving time data is valid positioning time data, the valid real-time positioning position data corresponding to the valid positioning time data is unique, and the valid real-time positioning position data is directly marked as valid positioning position data; the calculation formula of the positioning position deviation data in the positioning position deviation evaluation model is: ; in, To locate the position deviation data, , , They are respectively the effective first longitude data, the effective first latitude data, and the effective first altitude data, , , They are respectively the effective second longitude data, the effective second latitude data, and the effective second altitude data, , , They are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset motion trajectory display platform based on Beidou positioning); If all the real-time received time data are invalid positioning time data, the valid real-time positioning position data of the previous fixed time interval period will be marked as valid positioning position data.

[0045] According to an embodiment of the present invention, acquiring positioning parameters according to the positioning difference state, obtaining a positioning validity index according to the positioning parameters, and obtaining valid positioning position data after comparing the positioning validity index specifically include: If the positioning difference state is a consistent state, then averaging the valid first longitude data and the valid second longitude data to obtain mean longitude data, averaging the valid first latitude data and the valid second latitude data to obtain mean latitude data, and averaging the valid first altitude data and the valid second altitude data to obtain mean altitude data; The mean longitude data, the mean latitude data and the mean altitude data are used as effective positioning location data; If the positioning difference state is an inconsistent state, obtaining positioning parameters, including first signal strength data, first number of satellites and first signal stability data corresponding to the valid first real-time positioning position data, and second signal strength data, second number of satellites and second signal stability data corresponding to the valid second real-time positioning position data; Processing the first signal strength data, the first number of satellites and the first signal stability data through a preset positioning effectiveness evaluation model to obtain a first positioning effectiveness index; Processing the second signal strength data, the second number of satellites, and the second signal stability data through a preset positioning effectiveness evaluation model to obtain a second positioning effectiveness index; The first positioning validity index and the second positioning validity index are compared to obtain valid positioning position data.

[0046] It should be noted that, in this embodiment, if the positioning difference state is an inconsistent state, it means that the position data of the two positionings differ greatly, and it is necessary to determine which valid real-time positioning position data is more accurate. There are two valid real-time positioning position data, including valid first real-time positioning position data and valid second real-time positioning position data; the positioning parameters are corresponding parameters when the smart wearable device obtains the positioning position data, including signal strength data, number of satellites and signal stability data; the first signal strength data, the first number of satellites and the first signal stability data corresponding to the first positioning information are obtained, and the second signal strength data, the second number of satellites and the second signal stability data corresponding to the second positioning information are obtained; The calculation formula of the first positioning effectiveness index is: ; in, is the first positioning effective index, , , are respectively first signal strength data, first satellite number and first signal stability data, , , They are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset motion trajectory display platform based on Beidou positioning); The calculation formula of the second positioning effectiveness index is: ; in, is the second positioning effective index, , , They are respectively the second signal strength data, the second satellite number and the second signal stability data, , , They are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset motion trajectory display platform based on Beidou positioning); The first positioning validity index and the second positioning validity index are compared, and the larger one is used as the valid positioning position data.

[0047] According to an embodiment of the present invention, the real-time motion state data of the smart wearable device is obtained, and the real-time motion state data is combined with the effective positioning position data to obtain the fused position data through a preset fused position processing model, specifically including: Obtain real-time motion status data of smart wearable devices, including acceleration data, angular velocity data and direction data; The acceleration data, angular velocity data and direction data are combined with the effective positioning position data and processed through a preset position fusion processing model to obtain fused position data.

[0048] It should be noted that the smart wearable device is a process of motion, which involves acceleration data, angular velocity data and direction data. A smooth and accurate motion trajectory cannot be obtained based solely on positioning information, and individual signals may be lost in the middle. Therefore, it is necessary to obtain fused position data based on the acceleration data, angular velocity data, direction data and effective positioning position data through a preset position fusion processing model. The position fusion processing model is a computational model obtained through training with a large amount of historical data.

[0049] It is worth mentioning that it also includes: Obtain the planned motion trajectory data for the user's preset time period; Comparing the degree of overlap between the planned motion trajectory data and the real-time motion trajectory data to obtain a degree of overlap index; Comparing the overlap index with a preset route status evaluation threshold to obtain a motion trajectory status; Extracting a first threshold and a second threshold according to the preset route status evaluation threshold, wherein the first threshold is greater than the second threshold; comparing the overlap index with a first threshold and a second threshold; If the overlap index is greater than a first threshold, the motion trajectory state is a normal state; If the overlap index is greater than the second threshold and less than or equal to the first threshold, the motion trajectory state is abnormal, and the smart wearable device issues an abnormal reminder; If the overlap index is less than or equal to the second threshold, the motion trajectory state is a warning state, the smart wearable device issues a warning and simultaneously initiates a voice call with the management user.

[0050] It should be noted that smart wearable devices are widely used among teenagers. Parents can set the movement trajectory of students during the school hours, such as the movement trajectory of walking from school to home. When the student's overlap index is high, it means that the student is walking according to the established trajectory. In this embodiment, the route state evaluation threshold is set to: (0.85, 1], the movement trajectory state is normal; (0.6, 0.85], the movement trajectory state is abnormal; [0, 0.6], the movement trajectory state is warning state; when the calculated overlap index is 0.9, the movement trajectory state is normal.

[0051] It is worth mentioning that it also includes: Obtaining the motion parameters and standard parameters of different preset stages under the user's motion trajectory, the motion parameters include average heart rate data, average cadence data and average speed data, and the standard parameters include standard heart rate data, standard cadence data and standard speed data; Inputting the average heart rate data, average cadence data, average speed data, standard heart rate data, standard cadence data and standard speed data into a preset physical condition assessment model for processing to obtain a physical condition index; Comparing the physical condition index with a preset physical condition assessment threshold to obtain a physical condition; Extracting a third threshold and a fourth threshold according to the preset physical condition assessment threshold, wherein the third threshold is greater than the fourth threshold; comparing the physical condition index with a third threshold and a fourth threshold; If the physical condition index is greater than a third threshold, the physical condition is excellent; If the physical condition index is greater than the fourth threshold and less than or equal to the third threshold, the physical condition is in good condition; If the physical condition index is less than or equal to the fourth threshold, the physical condition is in a poor state.

[0052] It should be noted that during exercise, sometimes one wants to understand the correlation between the activity status and the physical condition under the trajectory or a segment of the trajectory, that is, to understand through the physical condition index. The smaller the physical condition index, the closer it is to the standard and the more in line with the standard physical condition. During exercise, within a certain range, a person's heart rate will increase with the increase of exercise frequency and the increase of exercise speed. The physical condition assessment model is a model obtained by training with a large amount of historical data, and the physical condition index can be calculated through the model. In this embodiment, the physical condition assessment threshold is set and updated according to the updated data in the historical exercise database obtained. The user's physical condition can be displayed in stages in the exercise trajectory to facilitate the user to understand his or her own physical condition.
