Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
As described in the background art, in the existing more intelligent badminton industry, only accurate micro-intelligent motion sensors are built in or out on a badminton racket to collect motion track data of the racket, and motion of a user holding the racket by the user using the racket is analyzed based on the motion track data of the racket. However, badminton is a general sport, and in addition to hand movements, movements of the lower limbs and feet are also critical, and in addition to the single-beat form, the double-beat form is also known. In view of the research report of the injury of the shuttlecock, the body parts with the highest incidence rate of the shuttlecock are respectively knees, shank achilles tendons, feet and the like.
Obviously, in the prior art, only aiming at a certain side of data acquired by a sensor on the racket, the whole motion process of a user cannot be comprehensively analyzed, and accurate analysis and evaluation results are given. Therefore, there is an urgent need to design a set of intelligent hardware capable of effectively evaluating the lower limb and foot exercise mode in badminton, so as to effectively judge the exercise characteristics of the lower limb or foot of a badminton player in the badminton process, and also perform model training through a large amount of data acquired in a historical time period, construct a badminton exercise model, analyze the acquired data based on the badminton exercise model, and provide comprehensive and accurate action analysis and corresponding action guidance for a user, thereby avoiding foot injury, exercising steps and improving the exercise experience of the user.
In order to solve the problem that in the prior art, various data of a user in the badminton process cannot be comprehensively obtained, and further scientific opinions and suggestions are difficult to accurately provide for the user, the embodiment of the specification provides a system for evaluating the badminton.
Specifically, a schematic structural diagram of a system 100 for evaluating badminton activities according to one or more embodiments of the present disclosure is shown in fig. 1, and includes:
an intelligent court 101 for collecting all movement track data of the intelligent insoles and/or shuttlecocks used by the user in a preset time within the coverage range of the intelligent court;
an intelligent insole 102 for collecting left and right foot movement data of a user within a predetermined time;
an intelligent shuttlecock 103 for collecting movement track data of the shuttlecock used by the user in a predetermined time;
wherein, all the motion trail data, the left foot motion data and the right foot motion data of the intelligent insoles and/or the shuttlecocks used by the users in the preset time and the motion trail data of the shuttlecocks used by the users in the preset time are used for evaluating the motion level of the users.
Optionally, in order to facilitate comprehensive evaluation of data collected by the intelligent court 101, the intelligent insole 102, and the intelligent shuttlecock 103, the system 100 for evaluating badminton activities provided in one or more embodiments of the present disclosure further includes: the evaluation device 104, the evaluation device 104 can evaluate the movement level of the user based on the data of all movement tracks of the intelligent insoles and/or shuttlecocks used by the user in a preset time and the data of the movement tracks of the shuttlecocks used by the user in a preset time.
Optionally, the evaluation device 104 may first extract the features of the left foot and right foot movement gait motion data, the motion track features and the motion track features of the shuttlecock used by the user in the predetermined time based on all the motion track data, the left foot and right foot motion data of the intelligent insole used by the user in the predetermined time and/or the motion track data of the shuttlecock used by the user in the coverage area of the intelligent court; and then, inputting the left foot and right foot movement gait motion data characteristics, the motion track characteristics and the motion track characteristics of the shuttlecock used by the user in the preset time into a shuttlecock motion model, and evaluating the motion level of the user, wherein the shuttlecock motion model is trained based on the left foot and right foot movement gait motion data characteristics, the motion track characteristic data and the motion track characteristic data of the shuttlecock used by the user in the preset time of a plurality of different motion levels.

As shown in fig. 2, a schematic diagram of a smart pitch 101 is provided for one or more embodiments of the present disclosure, where X may include a piezoelectric sensor or may include an RFID receiver. When X includes a piezoelectric sensor, it is preferable that the piezoelectric sensor may be a circular piezoelectric sensor having a diameter of 10mm for cost saving. More specifically, as shown in fig. 3, a schematic structural diagram of the intelligent playing field 101 provided in one or more embodiments of the present disclosure includes an acrylic layer 1011, a piezoelectric sensor layer 1012, and an acrylic layer 1013, and the thickness of each layer may be between 2 and 3mm so as not to affect the sensitivity of the piezoelectric sensor layer 1012.

In order to save the cost of deploying the intelligent court 101 and prolong the service life of the intelligent court 101, in one or more embodiments of the present disclosure, the pressure signals detected by the piezoelectric sensors disposed in the intelligent court 101 are in the form of "0" and "1", and since the piezoelectric signals detected by the piezoelectric sensors of this type do not include specific pressure values, on one hand, power can be saved, and on the other hand, since the time difference between occurrence of adjacent pressure signals "1" can be determined, the capability of instantaneous feedback can be given. The piezoelectric sensors deployed in the intelligent court 101 may be arranged in an array matrix with a unique identification for each unit area. When a user steps on a certain area of the intelligent court 101, the area generates a pressure signal, for example, a signal in the form of "1" is generated on a piezoelectric sensor on the corresponding area generating pressure, and the signal also contains a unique identifier of the area. After the evaluating device 104 receives this pressure signal, the specific location of the user can be determined, and after the evaluating device 104 receives a series of this pressure signals, the movement track of the user on the intelligent court surface 101 can be determined since the time generated by the pressure signal can also be determined.

Obviously, the mode based on the motion trail of the user acquired by the piezoelectric sensor and the RFID receiving device and the induction system also effectively solves the problem that the GPS positioning device cannot be applied indoors and accurately acquires motion trail data. To detect the contact time of the user's left and right feet with the insole, three piezoelectric sensors may also be provided in the smart insole 102.
In addition, in order to facilitate timely processing and transmission of data collected by the three RFID tags disposed on the smart insole 102, the smart insole 102 further includes an integrated circuit 1023, and the integrated circuit 1023 includes a circuit board, a signal processing chip, a battery, a wireless transmission device, and the like.
