When a candidate examinee carries out candidate training for swimming, data services such as accurate swimming distance, swimming duration and swimming speed need to be acquired. Some existing methods for measuring speed of swimming are generally to set a touch sensor on the wall of the swimming pool, start timing when a person starts from a starting point, then press the touch sensor on the wall of the pool with a finger at an end point, so as to obtain the arrival time, calculate the distance from the starting point to the end point, and count the interval time from the starting point to the end point, so as to calculate the average speed from the starting point to the end point of the swimming pool.

In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

In some embodiments of the present application, please refer to fig. 1, and fig. 1 is a schematic flow chart of a basic method for acquiring and displaying swimming speed measurement data according to an embodiment of the present application, which is detailed as follows:

in step S11, base station mapping information based on the swimming pool layout is provided to the speed measurement tag worn by the user, wherein the base station mapping information includes coordinate information of a plurality of base stations.

In this embodiment, the number of base stations and the base station positioning points are determined according to the actual size of the swimming pool, and then the base stations are arranged for the swimming pool according to the base station positioning points and the number of the base stations, so as to construct a speed measurement system for the swimming pool. In this embodiment, the number of base stations in the velocity measurement system is greater than or equal to 3. In this embodiment, a two-dimensional planar coordinate system is constructed by selecting one of the base stations arranged for the swimming pool as the origin of coordinates, then mapping the remaining base stations according to the planar coordinate system to determine the coordinate information corresponding to each base station, and backing up the coordinate information of all the base stations in the management background of the speed measurement system, thereby constructing a speed measurement system for the swimming pool. Based on this system of testing the speed, the user only needs to get into this swimming pool swimming through wearing the label that tests the speed that matches with this system of testing the speed, can trigger the system of testing the speed and carry out the swimming according to this user's swimming process in the swimming pool and test the speed to this user, obtains this user's swimming data of testing the speed. In this embodiment, before the user worn the label that tests the speed and got into the swimming pool, through the label communication connection that tests the speed of wearing with the user, the label that tests the speed of wearing to the user provides the basic station mapping information who lays based on the swimming pool to in the position that the user is located in the swimming pool is confirmed to the coordinate information of a plurality of basic station that contains in the basic station mapping information.

In step S12, the coordinate information of a plurality of base stations in the base station mapping information is combined, a distance value between the speed measurement tag and each base station is obtained in a bidirectional distance measurement manner, and the speed measurement tag is located according to the distance value between the speed measurement tag and each base station, so as to obtain the coordinate information of the speed measurement tag.

In this embodiment, the speed measurement tag communicates with each base station installed in the swimming pool, for example, UWB (ultra wide band) is a carrier-free communication technology, and data is transmitted by using nanosecond to microsecond non-sine wave narrow pulses. In this embodiment, based on the communication between the velocity measurement tag and each base station, a two-way ranging (Time Of Flight, abbreviated as TOF) manner is adopted to obtain a distance value between the velocity measurement tag and each base station. After the distance values between the speed measuring label and each base station are obtained, if the number of the base stations arranged based on the swimming pool is more than 3, 3 base stations are selected from the plurality of base stations, the position of the speed measuring label in a plane coordinate system is determined by adopting a three-point positioning algorithm according to the coordinate information of the 3 base stations, and then the coordinate information corresponding to the position is obtained to be used as the coordinate information of the speed measuring label.

In step S13, the moving track of the user in the swimming pool is obtained according to the coordinate information of the speed measurement tag, and the displacement direction of the user is recorded.

In this embodiment, the moving track of the user in the swimming pool is formed by connecting positions corresponding to the coordinate information of the plurality of speed measuring labels in time sequence, and the speed measuring labels can be positioned continuously. In this embodiment, the displacement direction of the user is recorded in real time during the process of continuously positioning the speed measurement tag, for example, when the speed measurement tag is positioned to obtain the second coordinate information, in the planar coordinate system, the position corresponding to the first coordinate information obtained by positioning the speed measurement tag points to the position corresponding to the second coordinate information obtained by positioning the speed measurement tag at the time, so as to record the displacement direction of the user in real time. By analogy, when the third coordinate information obtained by positioning the speed measuring label is obtained, the position corresponding to the second coordinate information points to the position corresponding to the third coordinate information obtained by positioning the speed measuring label at the moment, so that the displacement direction of the second user is recorded in real time. When the speed measuring label is positioned to obtain a new coordinate information, the position corresponding to the coordinate information obtained before points to the position corresponding to the coordinate information obtained newly, so that a new displacement direction is recorded in real time until the speed measuring label is stopped being positioned.

Step S14: and carrying out speed measurement analysis processing on the swimming process of the user according to the moving track and the displacement direction to obtain a corresponding speed measurement data result, and displaying the speed measurement data result to the user.

In this embodiment, a corresponding timestamp is provided at a position corresponding to each coordinate information in the moving track, and the timestamp represents time information of the user at the position of the coordinate point. After obtaining a moving track and a displacement direction of a user in a swimming process, performing speed measurement analysis processing on the swimming process of the user according to the moving track and the displacement direction, for example, calculating a distance value between two coordinate positions according to a coordinate point for a coordinate position in the moving track, and obtaining the displacement between the two coordinate positions by combining the distance value with the displacement direction recorded for the two coordinate positions before. For example, the time length taken to move from one coordinate position to another coordinate position in the displacement direction may be calculated based on the time stamps corresponding to the two coordinate positions. Based on the displacement between the two coordinate positions obtained by the above calculation and the corresponding time length, the speed of the user between the two coordinate positions can be calculated according to the formula of displacement-speed-time length. In this embodiment, according to the speed measurement analysis processing, speed measurement data such as an average speed, an overall distance, an overall duration, a fastest speed of the user swimming this time, and distances, durations, and speeds of displacement segments divided according to the coordinate position can be calculated according to the coordinate position recorded in the moving track.

It can be understood that, in this embodiment, the precision of the speed measurement data result displayed to the user may be flexibly set according to the requirement of the user, for example, the corresponding displacement distance and the time spent on each two adjacent coordinate positions in the moving track may be calculated, or the corresponding displacement distance and the time spent on each n coordinate positions may be calculated, and at this time, the data of the first and last coordinate positions are used for calculation. Furthermore, the speed of each displacement segment divided according to the coordinate position can be displayed in a data visualization chart mode.

It can be understood that, in the present embodiment, please refer to fig. 2 together, and fig. 2 is a schematic diagram of a speed measurement data result displayed to a user in the method for acquiring and displaying swimming speed measurement data according to the embodiment of the present application. As shown in fig. 2, a moving track generation diagram of the user swimming is shown to the user.

The method for acquiring and displaying swimming speed measurement data provided by the embodiment continuously positions the user to acquire the coordinate information of the user in the swimming process of the user through a speed measurement system constructed based on the swimming pool in a bidirectional distance measurement mode, and further obtains the moving track of the user in the swimming pool according to the coordinate information and records the displacement direction of the user, so that the speed measurement data is unrelated to the shape and the size of the swimming pool, and the problem of inaccurate swimming speed measurement caused by the fact that the swimming pool is irregular and the size of the swimming pool is not standard can be solved. Moreover, the user is continuously positioned in the swimming process of the user in a bidirectional distance measurement mode to obtain the coordinate information of the user, so that the moving track of the user in the swimming pool can be accurately reflected, speed measurement analysis is carried out according to the moving track, various speed measurement data such as average speed, integral distance, integral duration, fastest speed, distance, duration, speed and the like of each displacement section divided according to the coordinate position can be provided for the user, and data service is conveniently provided for the user.

As shown in fig. 4, the three-point positioning algorithm can construct an algorithm equation set for determining the coordinate information of the speed measurement tag by using the coordinate information of three base stations (e.g., base station 1, base station 2, and base station 3) and corresponding distance values between the base stations and the speed measurement tag, where the specific algorithm equation set is as follows:

step S52: if the mutual position relation of the three positioning circles is that the three circles are intersected and more than one intersection point exists, carrying out equal-proportion reduction processing on the three circles until the three circles are intersected and the intersection point exists only; and if the mutual position relation of the three positioning circles is that at least one of the three circles does not intersect, carrying out equal-proportion amplification processing on the three circles until the three circles intersect and have a unique intersection point.

In this embodiment, due to the influences of signal interference, inaccurate mapping, object movement and the like, the distance value between the base station and the velocity measurement tag obtained by bidirectional distance measurement is difficult to have zero error in most cases, and therefore, when the velocity measurement tag is positioned by adopting a three-point positioning algorithm, the three positioning circles may have the situation that the three positioning circles are not intersected and have a unique intersection point. Therefore, before the coordinate information of the speed measurement tag is acquired, the size of the three positioning circles can be adjusted according to the position relationship by identifying the position relationship of the three positioning circles, so that the three positioning circles are adjusted until there is only one intersection point. In this embodiment, after the circle drawing process is performed based on three base stations, the positional relationship between the three positioning circles is identified, wherein the positional relationship between the three positioning circles is roughly divided into the following three types: the first is that ideally three circles intersect and have a unique intersection point, the second is that three circles intersect and have more than one intersection point (e.g., fig. 6-a), and the third is that at least one circle does not intersect (e.g., fig. 6-b). For the above three positional relationships, the first one may directly obtain the unique intersection point as the location point of the speed measurement tag without adjusting the size of the location circle, while for the second and third ones, since one unique intersection point cannot be determined, the sizes of the three location circles need to be adjusted through smoothing processing (for example, fig. 6-c) so as to adjust the three location circles until one unique intersection point can be determined. In the present embodiment, the smoothing process includes: for three positioning circles with the position relation of three intersected circles and more than one intersection point, carrying out equal-scale reduction processing on the three circles until the three circles are intersected and have the only intersection point; and for the position relation that at least one of the three circles does not intersect, carrying out equal-proportion amplification treatment on the three circles until the three circles intersect and have a unique intersection point. Based on the smoothing processing, the problem that the unique intersection point cannot be determined in the actual positioning process can be solved.
