The following description describes how to perform a knee-knee sit-up test with the knee-capping sit-up detector system of the present invention. Referring to FIG. 1 to FIG. 3 and FIG. 6 together, the knee-sit-up detector system 100 is first provided (step S10), and the user may first place the user's identity mark M at the corresponding position of the identity recognition module 20. (See FIG. 6, for example, placing the identity mark M above the identity recognition module 20, or moving the identity mark M to a position detectable by the identity recognition module 20). After the identity recognition module 20 recognizes the user's identity mark M (step S20), the control module 50 activates the output module 30 to issue a command for starting, for example, a voice or video (step S30, for example, "please lay flat" The voice of the knee-preparing posture is displayed on the display screen (not shown) on a floor or plane and the knees are bent at about 90 degrees. In the present invention, the back sensor 12, the two hand sensors 14, the two leg sensors 16, the identification module 20, and the output module 30 can be electrically connected to the control module 50, for example, by wires. In order to make the drawing simple, the wires are not shown in Fig. 6).

Subsequently, the user lie flat on the ground or plane according to the aforementioned start command and bend the knees to about 90 degrees (see Fig. 6). Then, the user can start the measurement when the user sits up from the plane G (for example, the ground) by the abdominal muscle force (see FIG. 7), because the upper body is off the ground or the plane, The back sensor 12 disposed on the back of the user is switched from the original touch state to the non-touch state. When the first back sensor 12 is switched from the touch state to the non-touch state, the back sensor 12 generates one. Timing signal to control module 50. When the control module 50 receives the timing signal, it indicates that the timing starts (for example, one minute). During a predetermined time interval (for example, one minute), the user then presses the two elbows sequentially or simultaneously to the leg sensor 16 to cause the two leg sensors 16 to generate the first trigger signal and the second trigger signal, respectively. The control module 50 (step S40). After receiving the first trigger signal and the second trigger signal, the control module 50 determines whether the trigger time difference between the first trigger signal and the second trigger signal generated by the two leg sensors 16 is less than a preset trigger time difference ( For example, less than 100 milliseconds), if the trigger time difference between the first trigger signal and the second trigger signal is less than 100 milliseconds, the first trigger signal and the second trigger signal generated by the double elbow touch leg sensor 16 For a valid number of times. Subsequently, the user rests the upper body back on the ground or plane to return to the lying preparation action (see FIG. 6), so that the back sensor 12 is in a touch state. After repeated buckling, the elbows touch the leg sensor 16 and then resume the lying preparation action, the control module 50 receives the plurality of first ones generated by the multiple elbows repeatedly touching the leg sensor 16. The triggering signal and the plurality of second triggering signals, when the posture is correct, the control module 50 counts the sum of the effective times of the first triggering signal and the second triggering signal to obtain the total effective number of times (step S50). For example, in a preset time interval of one minute, if the user completes 20 knee-ups (the effective number of 20) in the correct posture, the control module 50 will count the effective times to obtain the total effective number of times. Is 20.

After one minute has elapsed, the control module 50 causes the output module 30 to issue an end command such as a voice (step S60, for example, "send the measurement, stop the action"). When the user hears the end command, the user stops pressing or triggers the leg sensor 16 and the back sensor 12. Finally, the control module 50 integrates the total effective number with the user information (eg, identity) to integrate a measurement result (including the measured total effective number and user information), and the communication module 40 Wireless transmission of this measurement result Go to the database D (step S70). In the present invention, the communication module 40 can also be electrically connected to the control module 50 by wires, for example. (To simplify the drawing, the communication module 40 is not shown in FIG. 6, and the connection mode of the communication module 40 is required. see picture 1).

In addition, in a preset time interval of, for example, one minute, if the triggering time difference between the first trigger signal and the second trigger signal generated by the user's elbow-touching the leg sensor 16 is not less than the preset trigger time difference ( For example, if it is greater than 100 milliseconds) (indicating that the time of the two elbows touching the leg sensor 16 is too long), the control module 50 generates a reminder signal to the output module 30 to cause the output module 30 to issue a reminder command (for example, The light is emitted or the "Position is incorrect, please correct the posture" voice, or the words "posture error" or the screen is displayed on the display screen (not shown) (step S80). Similarly, if the user's hand does not properly touch the hand sensor 14 (ie, the user's two fingers or both palms are not placed in the correct position, for example, the user's shoulder), the control module 50 will generate a reminder. Signaling to the output module 30, so that the output module 30 issues a reminder command (for example, a light that emits light or "the posture is incorrect, please correct the posture", or displays a "posture error" or the like on the display screen. (Step S80). Similarly, if the user's back does not properly touch the back sensor 12 (ie, within a predetermined time interval of one minute, the user's back does not completely lie back to the ground or plane when the user lie back and prepare for the action. The control module 50 generates a reminder signal to the output module 30 to cause the output module 30 to issue a reminder command (for example, a light that emits light or "the posture is incorrect, please correct the posture", or is displayed on the display screen. A word or screen such as "posture error" (step S80).

When the output module 30 issues a reminder command, the control module 50 counts the first trigger signal and the second trigger signal generated by the predetermined period of time before and after the reminder command as invalid times (the posture is incorrect and is therefore invalid). If the user's posture is incorrect multiple times and the output module 30 issues multiple reminder commands, the control module 50 counts the sum of these invalid times as the total number of invalid times. And at the step In S70, the control module 50 further integrates the total invalid number with the total effective number and the user information (such as identity), and includes the measured total effective number, the total invalid number, and the user. The information is wirelessly transmitted to the database D by the communication module 40.

Thereby, the user can know whether the knee-sit-up posture is correct by whether the output module 30 issues a reminder command. Moreover, when the output module 30 issues a reminder command, the user can immediately adjust and correct the action, so as to avoid the number of invalid times of the incorrect posture after the preset time interval of one minute, and must be measured again. inconvenient.

In summary, the knee-sit-up detector system and method thereof of the present invention are provided by a knee-shoulder detection module, an identity recognition module, an output module, a communication module, and a control module. The sit-up detector system can automatically measure the subject's knee-sit-ups without the need for manual testing and interpretation. There will be no errors in interpretation, data transmission errors, labor costs, and no confidentiality. The problem arises. Moreover, it is possible to determine whether the user's posture is correct or not, and to avoid the problem that the measurement result is out of alignment due to the user's posture being incorrect. In addition, the encryption step is used to encrypt the measurement results to avoid the problem of capital leakage. The user can also identify the user's identity mark by the identity recognition module after the measurement to view or compare the measurement results of the user.
