Description

Technical Field

[0001] The present invention relates to the technical field of physical function data collection terminals in students' daily life and physical education teaching process, and in particular to a dynamic sports status monitoring terminal and a user identity determination method. Background Art

[0002] As competition in China's education becomes increasingly fierce, students are spending more and more time on their studies and less and less time on exercise. The direct consequence is that students' physical fitness is getting worse and worse. To reverse this situation, the domestic education department has introduced a double reduction policy to reduce students' learning burden and pressure, so that students have more time to participate in sports after class to improve their overall physical fitness. In addition, students' physical assessment will be included in the total score of the entrance examination to guide students to exercise in their daily lives. However, the above implementation methods are still insufficient and cannot effectively urge students to participate in physical exercise in their daily lives. If technical means are used to monitor and collect the time and intensity of students' physical exercise, and include it and the students' physical assessment results in the total score of the entrance examination, it can truly achieve the purpose of urging students to participate in physical exercise in their daily lives.

[0003] Currently, there are mature wearable electronic devices for recording human exercise time and intensity, such as smart watches; but there is a technical defect when using them to monitor and record students' daily physical exercise time and intensity: existing smart watches cannot detect the identity of the wearer, and there is a possibility of cheating when using them, that is, other people can wear smart watches to replace the monitored students' daily exercises and physical tests; if the wearer's identity detection function is added to the existing smart watches, the biometric technologies that can be used include fingerprint recognition, face recognition, iris recognition, finger vein recognition, etc., but there is a problem when the above biometric technologies are applied to smart watches to detect the wearer's identity: when fingerprint recognition, face recognition, iris recognition, and finger vein recognition are used, the smart watch and the identified biometric features can be separated, that is, the smart watch can identify the biometric features of non-wearers, so there is a possibility of cheating; therefore, how to ensure that the smart watch and the wearer's identified biometric features are inseparable is the key to solving the problem of cheating by others wearing smart watches instead of monitored students.

[0004] Normally, a smart watch is worn on the user's wrist when in use. If the smart watch collects the vein characteristics of the wearer's wrist that is in contact with the back of the smart watch and identifies the wearer's identity, it has the excellent characteristic that the smart watch wearer and the identified wrist vein biometrics are inseparable, so it is a better solution; however, there is a huge technical obstacle to integrating the vein recognition module into the smart watch for detecting wrist vein characteristics: the size of the vein recognition module in the axis direction of its lens module is much larger than the thickness of the smart watch, and the vein recognition module cannot be integrated into the smart watch at all to implement the shooting of the wrist veins that are in contact with the back of the smart watch; therefore, how to integrate the vein recognition module into the smart watch, shoot the wrist vein characteristics that are in contact with the back of the smart watch and identify the user has become an urgent problem to be solved for the actual implementation of the dynamic monitoring terminal for exercise status. Summary of the invention

[0005] In order to overcome the shortcomings of the background technology, the present invention discloses a dynamic motion status monitoring terminal, which is based on the volume of existing smart watches and is equipped with a newly designed plate-type vein camera module with a thickness of less than 3 mm. Before use, the wrist vein image of the authorized user is pre-recorded in the smart watch. When in use, the dynamic motion status monitoring terminal is worn on the wrist of the user, and the plate-type vein camera module regularly captures the wrist vein image of the user, and compares it with the wrist vein image of the authorized user stored in the smart watch to determine whether the user of the dynamic motion status monitoring terminal is the authorized user himself, thereby preventing This prevents cheating in that other people wear the dynamic exercise status monitoring terminal to replace the authorized user in daily physical exercise participation; in addition, a startup module and a startup connection module are set in the main wristband and the auxiliary wristband of the dynamic exercise status monitoring terminal. The smart watch detects the ID number set in the startup module through the startup connection module to determine the dynamic connection status of the main wristband and the auxiliary wristband, thereby preventing the dynamic exercise status monitoring terminal from briefly removing the dynamic exercise status monitoring terminal in the middle of the physical examination to change the user after confirming the authorized user through the wrist vein image, thereby ensuring the accuracy and fairness of the physical examination results.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a terminal for dynamic monitoring of exercise status, including a smart watch, a main wristband and an auxiliary wristband, wherein the main wristband and the auxiliary wristband are connected to the smart watch and are used to be worn on the wrist; the smart watch has functions such as clock, 4G communication, Bluetooth communication, radio frequency identification, payment, heart rate monitoring and recording, sleep monitoring and recording, satellite positioning, etc., and the smart watch can be used to monitor and record the time and intensity of the user's daily physical exercise; the smart watch is built with a newly developed and designed plate-type venous camera module, the biggest structural feature of which is that the thickness is less than 3 mm, and the plate-type venous camera The axis of the lens module in the module is parallel to the wrist being photographed, so it can be built-in in an existing smart watch. Before using the dynamic sports monitoring terminal, the wrist vein image of the authorized user needs to be recorded in advance. The recording of the wrist vein image can be taken by a dedicated device to obtain a complete vein image of the wrist of the authorized user, and then transmitted to the smart watch for storage through the 4G communication network or Bluetooth communication. The smart watch can also be set on the wrist of the authorized user, and the smart watch can be moved multiple times to take multiple local vein images of the authorized user's wrist, and then the complete vein image of the user's wrist is synthesized.

[0007] When the dynamic exercise status monitoring terminal is used, it is worn on the user's wrist, and the plate-type vein camera module captures the local vein image of the wrist, which is then compared with the complete vein image of the wrist of the authorized user stored in the smart watch to determine whether the user of the dynamic exercise status monitoring terminal is an authorized user, thereby preventing cheating by unauthorized users wearing the dynamic exercise status monitoring terminal to replace authorized users in daily physical exercise.

[0008] Furthermore, the plate-type vein camera module includes a module bracket, a flat reflector, a camera module A, and a camera module B; wherein the flat reflector is used to change the light propagation direction of the captured wrist vein image, compress the thickness of the plate-type vein camera module, so that it can be built-in in the smart watch; the thickness of the flat reflector is set to be less than 3 mm, so the maximum width of the wrist vein image captured by the flat reflector is only 3 mm, and the wrist vein features contained in such a small wrist vein image width range are relatively few, which will cause the problem of low accuracy and high misjudgment rate of vein image recognition results. To solve this problem, in the present invention, the plate-type vein camera module is provided with two groups of camera modules and corresponding flat reflectors, so that two wrist vein images with fixed relative positions can be obtained, and the two wrist vein images with fixed relative positions are jointly compared and recognized, thereby greatly improving the accuracy of wrist vein image recognition and reducing the misjudgment rate;

[0009] The module bracket is the basic structural part of the plate-type vein camera module, and its purpose is to provide structural support for the flat reflector, camera module A, and camera module B; the module bracket is a rectangular frame with two rectangular through holes in the middle, camera module A and a flat reflector are fixedly arranged in one rectangular through hole, and camera module B and another flat reflector are fixedly arranged in the other rectangular through hole; the two rectangular through holes are respectively provided with a supporting inclined plane A and a supporting inclined plane B, and the supporting inclined plane A and the supporting inclined plane B are located on the side surfaces in the same direction of the two rectangular through holes. With this structural setting of the supporting inclined plane A and the supporting inclined plane B, the two wrist local vein images taken are about 8 mm apart, and this distance makes the two wrist local vein images have a certain difference, which is conducive to the accuracy of the joint comparison and recognition results of the wrist vein images;

[0010] The flat reflector is in the shape of a flat plate, and its thickness is equal to that of the module bracket. A reflective bevel is provided on one side of the flat reflector, and the reflective bevel is coated with a total reflection film. The flat reflector uses the reflective bevel to change the propagation direction of infrared light, thereby realizing a structure in which the axis of the lens module in the camera module is set to be parallel to the photographed wrist, thereby achieving the purpose of compressing the thickness of the plate-type vein camera module and realizing that the plate-type vein camera module is built into the smart watch; the flat reflector is fixedly set in the rectangular through hole of the module bracket, and the reflective bevel corresponds to the supporting bevel A and the supporting bevel B. The reflective bevel angle of the flat reflector is designed to be equal to the supporting bevel A and the supporting bevel B, and the supporting bevel A and the supporting bevel B can be used as the assembly positioning and fixing surfaces of the flat reflector , achieving precise positioning and reliable fixation of the flat reflector assembly, reducing the overall thickness of the plate-type vein camera module to the greatest extent, and the flat reflector is fixed to the module bracket by adhesive bonding; the plate surface corresponding to the reflective bevel is the working surface. When the plate-type vein camera module is working, the working surface is facing the wrist skin of the wearer of the dynamic motion monitoring terminal, and the infrared light is emitted from the working surface, irradiated on the wrist of the wearer, and then enters the working surface after being reflected by the wrist; the side surface corresponding to the reflective bevel is provided with a camera surface and a fill light surface, the camera surface is located in the middle, and the fill light surface is located on both sides of the camera surface; the camera surface, fill light surface, and working surface of the flat reflector are light-transmitting surfaces, and the remaining surfaces are coated with a black light-absorbing film, which is used to absorb infrared light outside the imaging surface to improve the final imaging quality;

[0011] The camera module A includes a camera module A soft film circuit board, an infrared LED, and an infrared camera chip. Two infrared LEDs are provided. The infrared camera chip and the infrared LEDs are arranged in a linear shape and are fixedly arranged on the camera module A soft film circuit board. The infrared LEDs are located on both sides of the infrared camera chip. A lens module is fixedly arranged at the front end of the infrared camera chip.

[0012] The camera module B includes a camera module B soft film circuit board, an infrared LED, an infrared camera chip, and a lens module. The infrared camera chip, the infrared LED, and the lens module are arranged and fixed on the camera module B soft film circuit board in the same manner as the camera module A.

[0013] The camera module A and the camera module B are fixedly arranged in the rectangular through-hole of the module bracket, the lens module corresponds to the camera surface, and the infrared LED corresponds to the fill light surface; the working principle of the plate-type vein camera module is as follows: the infrared LED emits infrared light, which enters the flat reflector through the fill light surface of the flat reflector, and then changes direction through the reflecting inclined surface of the flat reflector, and is emitted from the working surface of the flat reflector, vertically irradiates the wearer's wrist, re-enters the working surface of the flat reflector after being reflected by the wrist, and then changes direction through the reflecting inclined surface of the flat reflector, is transmitted in the flat reflector, and finally enters the lens module, and after being focused by the lens module, an image is formed on the infrared camera chip; there is abundant infrared light under the superficial skin of the wearer's wrist. The wrist is rich in veins. Since venous blood has a high absorption rate of infrared light, the infrared light reflected by the wrist contains the information of the veins under the superficial skin of the wearer's wrist, that is, the final image on the infrared camera chip is actually the local vein image of the wearer's wrist. The width of the local vein image of the wrist is the width of the working surface corresponding to the reflecting slope of the flat reflector, which is basically equal to the thickness of the flat reflector; the soft film circuit board of camera module B is electrically connected to the soft film circuit board of camera module A; when the plate-type vein camera module is working, camera module A and camera module B each independently take a local vein image of the wrist, which is transmitted to the smart watch through the soft film circuit board of camera module B and the soft film circuit board of camera module A.

[0014] Preferably, the support inclined plane A and the support inclined plane B of the module bracket are located on the inner side surfaces adjacent to the two rectangular through holes, and the two wrist local vein images taken are about 0.2 mm apart. The two wrist local vein images can be merged into a wrist local vein image with a width of about 6 mm by interpolating pixels. The wrist local vein image of this width already contains more wrist vein features, so it can be identified by the usual vein recognition method. In addition, when the smart watch is used to collect the complete vein image of the authorized user's wrist, the collection workload is small and the success rate is relatively high. If the module is used The support bevel A and the support bevel B of the block bracket are located on the inner side surfaces away from the two rectangular through holes. The two local wrist vein images taken by it are about 15 mm apart. This distance makes the two local wrist vein images have significant differences. The accuracy of the recognition results can be significantly improved when the wrist vein images are jointly compared and recognized. However, when a smart watch is used to collect a complete vein image of the authorized user's wrist, the collection workload is large and the success rate is relatively low. Therefore, it is recommended to use proprietary equipment to collect the complete vein image of the authorized user's wrist, and then transmit it to the smart watch for storage via the 4G communication network or Bluetooth communication.

[0015] Furthermore, the lens module includes a lens frame and a lens, wherein the lens is embedded in the lens frame; the lens adopts a GRIN cylindrical lens or a spherical lens or an aspherical lens.

[0016] Furthermore, a through hole is provided on the bottom cover of the smart watch, and a bottom cover glass is fixedly arranged at the through hole; the working surface of the flat reflector of the plate-type vein camera module faces the bottom cover glass.

[0017] Furthermore, an ambient light sensor is fixedly provided on the bottom cover of the smart watch, and the ambient light sensor is used to assist in detecting whether the dynamic motion status monitoring terminal is out of the wearing state; when the dynamic motion status monitoring terminal is normally worn on the wrist of the authorized user, the ambient light sensor will be blocked by the wrist, and at this time the ambient light sensor has no output signal. When the authorized user takes off the dynamic motion status monitoring terminal, the ambient light sensor will detect the surrounding light and output a signal to the smart watch. At this time, the identity recognition and authentication of the original wearer will be invalid, and the wearer's wrist vein image must be re-compared to determine whether the user of the dynamic motion status monitoring terminal is an authorized user; in addition, when the ambient light sensor detects the surrounding light and outputs a signal to the smart watch, the smart watch will stop detecting the ID code in the startup module and taking the wearer's wrist vein image for comparison and identification, so as to save the power consumption of the smart watch and extend the standby time.

[0018] Furthermore, the main wristband is built with a startup module, in which an ID code is preset, and the auxiliary wristband is built with a startup connection module, which is electrically connected to the smart watch; when the main wristband is connected to the auxiliary wristband, the startup module in the main wristband is connected to the smart watch through the startup connection module in the auxiliary wristband, and the smart watch determines the connection status of the main wristband and the auxiliary wristband by periodically reading the ID code stored in the startup module, and indirectly determines whether the dynamic sports status monitoring terminal is worn on the wrist; the purpose of setting this structure and function is to prevent the dynamic sports status monitoring terminal from confirming the authorized use through the wrist vein image After identifying the wearer, the dynamic exercise status monitoring terminal is taken off by covering the ambient light sensor and worn on the wrist of an unauthorized user to cheat during a short-term physical examination, thereby ensuring the accuracy and fairness of the physical examination results; when the dynamic exercise status monitoring terminal is working normally, the plate-type vein camera module captures the wearer's wrist vein image at a set period for identification, and at the same time reads the ID code stored in the startup module at a set period to determine the wearing status of the dynamic exercise status monitoring terminal, but the working cycle of the plate-type vein camera module is much longer than the cycle of reading the ID code stored in the startup module.

[0019] Furthermore, the main wristband includes a main wristband body and a start-up module. The main wristband body is made of flexible material. The start-up module includes a soft film circuit board, a strong magnet electrode, and an identification chip. The strong magnet electrode and the identification chip are fixedly arranged on the soft film circuit board, and the strong magnet electrode is electrically connected to the identification chip. The start-up module is embedded at the end of the main wristband away from the smart watch, and the strong magnet electrode is exposed on the surface of the main wristband body.

[0020] The auxiliary wristband includes an auxiliary wristband body and a starting connection module. The auxiliary wristband body is made of flexible material. The starting connection module includes a starting connection module soft film circuit board and a connecting electrode. The connecting electrode is fixedly arranged on the starting connection module soft film circuit board. The starting connection module is embedded in the auxiliary wristband body, and the connecting electrode is exposed from the surface of the starting connection module soft film circuit board. There are several groups of connecting electrodes, which are arranged along the length direction of the auxiliary wristband. When different groups of connecting electrodes are adsorbed with strong magnet electrodes, the connection length between the main wristband and the auxiliary wristband can be adjusted to adapt to the wrist diameters of different wearers. One end of the starting connection module soft film circuit board extends out of the auxiliary wristband body and is electrically connected to a smart watch. When the strong magnet electrode of the main wristband is correspondingly attracted with the connecting electrode of the auxiliary wristband, the starting module in the main wristband is electrically connected to the smart watch through the starting connection module of the auxiliary wristband.

[0021] A method for determining the identity of a user of a sports status dynamic monitoring terminal comprises the following steps:

[0022] S1. Recording of wrist vein images of authorized users: Turn on the smart watch and send an encrypted wrist vein image acquisition instruction to the smart watch via Bluetooth; Stick the bottom cover of the smart watch to the wrist, move the smart watch along the forearm for several times, and use the plate-type vein camera module to capture the complete vein image of the authorized user's wrist, store it in the smart watch, and upload it to the back-end monitoring cloud platform via the 4G communication network;

[0023] S2. Confirmation of wearing status of the dynamic sports monitoring terminal: The smart watch is placed on the wrist of the authorized user, and the main wristband and the auxiliary wristband are wrapped around the wrist, so that the strong magnet electrode of the main wristband and the connection electrode of the auxiliary wristband are correspondingly attracted, and the start-up module in the main wristband is electrically connected to the smart watch through the start-up connection module of the auxiliary wristband; at this time, the ambient light sensor has no output signal, and the smart watch determines the connection status of the main wristband and the auxiliary wristband by reading the ID code stored in the start-up module, and indirectly determines whether the dynamic sports monitoring terminal is worn on the wrist;

[0024] S3. Identification of the wearer's identity of the dynamic motion status monitoring terminal: When it is determined that the dynamic motion status monitoring terminal is worn on the wrist, the plate-type vein camera module periodically captures the wearer's wrist vein image, and compares it with the wrist vein image of the authorized user stored in the smart watch to determine whether the wearer of the dynamic motion status monitoring terminal is an authorized user; if the dynamic motion status monitoring terminal determines that the wearer is an authorized user, the heart rate monitoring and recording function of the smart watch is turned on, and the heart rate monitoring record results are uploaded to the back-end monitoring cloud platform through the 4G communication network at regular intervals; if the dynamic motion status monitoring terminal determines that the wearer is an unauthorized user, the wearer's wrist vein image captured by the plate-type vein camera module is uploaded to the back-end monitoring cloud platform through the 4G communication network, and the back-end monitoring cloud platform compares the stored wrist vein image of the authorized user to determine the identity of the unauthorized user, and sends a warning message to the smart watch through the 4G communication network.

[0025] Furthermore, the specific method of identifying the wearer of the motion status dynamic monitoring terminal is as follows:

[0026] S31, grayscale processing and binarization processing are performed on the complete vein image of the authorized user's wrist to obtain a binary image of the complete vein of the authorized user's wrist; and then the binary image of the complete vein of the authorized user's wrist is refined to obtain a refined image of the complete vein of the authorized user's wrist; the complete vein image of the authorized user's wrist, the binary image of the complete vein of the authorized user's wrist, and the refined image of the complete vein of the authorized user's wrist are all stored in the smart watch;

[0027] S32. When the smart watch is worn on the wrist for judging the dynamic monitoring terminal of the movement status, the plate-type vein camera module captures the vein image of the wearer's wrist, and obtains the local vein image A and the local vein image B through the camera module A and the camera module B; grayscale processing and binarization processing are performed on the local vein image A and the local vein image B to obtain the local vein binary image A and the local vein binary image B; the local vein binary image A and the local vein binary image B are then refined to obtain the local vein refined image A and the local vein refined image B; the camera module A is used to obtain the local vein binary image A and the local vein binary image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein refined image A and the local vein refined image B; the camera module A is used to obtain the local vein binary image A and the local vein binary image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein refined image A and the local vein refined image B; the camera module A is used to obtain the local vein binary image A and the local vein binary image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein refined image A and the local vein refined image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein refined image A and the local vein refined image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein binary image A and the local vein binary ... binary image A and the local vein binary image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein binary image A and the local vein binary image B; the local vein binary image A and the local vein binary image B are refined to obtain the local vein binary image A and the local vein , the relative position of the camera module B, the local vein binary image A and the local vein binary image B are merged into a local vein binary image, and the local vein thinning image A and the local vein thinning image B are merged into a local vein thinning image; it is supplemented that: the local vein binary image only contains the image and relative position information of the local vein binary image A and the local vein binary image B, and other image information except the local vein binary image A and the local vein binary image B does not participate in the image comparison and recognition process, so as to reduce the calculation amount of image comparison and recognition;

[0028] S33, make a fixed thread in the middle of the local vein thinning image A or the local vein thinning image B in the width direction, the fixed thread intersects with the thin line in the local vein thinning image A or the local vein thinning image B to generate a thread intersection point, and take the fixed thread intersection point with the thread intersection point of the thickest vein as the origin; take the origin of the local vein thinning image as the reference point, take the thinning line of the thickest vein in the complete vein thinning image of the wrist of the authorized user as the trajectory, and slide the local vein binary image in the complete vein binary image of the wrist of the authorized user; when the local vein binary image A and the complete vein binary image of the wrist of the authorized user intersect, When the overlap rate reaches the maximum value and exceeds the set threshold, the overlap rate of the local vein binary image B and the complete vein binary image of the authorized user's wrist also reaches the maximum value and exceeds the set threshold, then the wearer of the dynamic motion monitoring terminal is determined to be an authorized user; if the overlap rate of the local vein binary image A, the local vein binary image B and the complete vein binary image of the authorized user's wrist cannot reach the maximum value at the same time, or the overlap rate is always lower than the set threshold, then the wearer of the dynamic motion monitoring terminal is determined to be an unauthorized user; Supplementary explanation: 1. When the wearer of the dynamic motion monitoring terminal In the wearer's identity recognition, the origin of the local vein thinning image is used as the reference point, and the thinning line of the thickest vein in the complete vein thinning image of the authorized user's wrist is used as the trajectory to slide the local vein binary image in the complete vein binary image of the authorized user's wrist, so as to reduce the amount of image matching calculation and shorten the recognition time; second, when the overlap rate of the local vein binary image A and the complete vein binary image of the authorized user's wrist reaches the maximum value and exceeds the set threshold, the overlap rate of the local vein binary image B and the complete vein binary image of the authorized user's wrist also reaches the maximum value and exceeds the set threshold. If the set threshold is exceeded, the determination condition for determining that the wearer of the motion status dynamic monitoring terminal is an authorized user is actually a three-dimensional determination condition, namely, the overlap rate of local vein binary image A, the overlap rate of local vein binary image B, and the synchronous reaching of the maximum value, wherein the synchronous reaching of the maximum value is a correlation dimension generated based on the feature that the relative positions of local vein image A and local vein image B are fixed, which is used to exclude the possible non-correlated maximum values ​​of the overlap rate of local vein binary image A or the overlap rate of local vein binary image B, so as to improve the accuracy of the comparison and recognition results and reduce the misjudgment rate.

[0029] Due to the adoption of the technical solution as described above, the present invention has the following beneficial effects: based on the volume of the existing smart watch, a plate-type vein camera module with a thickness of less than 3 mm is built-in, and the wrist vein image of the authorized user is pre-recorded in the smart watch before use. When in use, the dynamic motion status monitoring terminal is worn on the wrist of the user, and the plate-type vein camera module regularly captures the wrist vein image of the user, and compares it with the wrist vein image of the authorized user stored in the smart watch to determine whether the user of the dynamic motion status monitoring terminal is the authorized user himself, thereby preventing other people from wearing the dynamic motion status monitoring terminal to replace the authorized user to participate in daily physical exercise. The cheating problem; in addition, a startup module and a startup connection module are set in the main wristband and the auxiliary wristband of the dynamic motion status monitoring terminal. The smart watch detects the ID number set in the startup module through the startup connection module, and determines the dynamic connection state of the main wristband and the auxiliary wristband, thereby preventing the dynamic motion status monitoring terminal from temporarily removing the dynamic motion status monitoring terminal to change the user for physical examination after confirming the authorized user through the wrist vein image, thereby ensuring the accuracy and fairness of the physical examination results.

DETAILED DESCRIPTION

[0054] The present invention can be explained in detail by the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
