When the user's feet and hands are correctly contacted or abutted against the abutting member 14 and the moving member 16, the output module 30 will then issue a "start measurement" voice or display screen, and the user can follow the self. The physical condition moves or contacts the hand of the moving member 16 to move the moving member 16 in accordance with the direction D1 (see Fig. 1). After the moving member 16 is pushed by the user's hand and moved to a position d from the reference point 12 (see FIG. 3), the integral front bending length value (the body front bending length value shown in FIG. 3) can be obtained. It is 25 cm) (step S40). Finally, the control module 50 integrates a measurement result (including the measured body front bend length value and user information) according to the aforementioned body front bend length value combined with user information (such as identity), and The communication module 40 wirelessly transmits the measurement result to the database D (step S50).

In addition, since the sitting posture front bend detector system 100 of the present invention can also include a plurality of correction points 60 disposed on the moving path of the moving member 16, the current one user does not need to return the moving member 16 after the current user finishes using it. Returning to the reference point 12 (i.e., returning to zero action), the sitting posture front bend detector system 100 of the present invention can be used, if the physical condition of the next user (the physical condition in the present invention refers to the body softness) ) permission, the next user only needs to push the moving part 16 to the direction D1 (see 3), when one of the correction points 60 passes during the movement of the moving member 16, the calibration point 60 of the electrical connection control module 50 causes the control module 50 to perform a correction step (step S70) to the next bit. The user's body front bend length value is corrected; if the next user's physical condition is worse than the previous user, only the moving member 16 needs to be moved slightly toward the reference point 12 (no need to move) The piece 16 is fully pushed back to the reference point 12), and the measurement can be continued. Thereby, when measuring the softness of a plurality of users, the next user can continue to perform the measurement without performing multiple zeroing operations. Further, since the moving member 16 performs the correcting step S70 when passing through the correction point 60, there is no problem that the measured body front bending length value misalignment error does not occur.

In summary, the sitting posture front bend detector system and the method thereof can solve the problem that the conventional technique cannot achieve automatic measurement, personal security, and correct measurement of the body front bend when performing the sitting body front bend measurement. The problem of the length value.

For the purpose of bending the length value, there is no need for manual detection and interpretation, and no one will have problems for interpretation errors, data transmission errors, labor costs and no confidentiality. Moreover, by the plurality of correction points disposed on the moving path of the moving member, when the moving member passes through one of the correction points, the control module performs the correcting step, thereby correcting the body front bending length value. In addition, by means of a plurality of sensors disposed on the abutting member and the moving member, it is possible to sense whether the user's feet and hands are against the abutting member and the moving member, thereby preventing the user from being incorrectly postured. The problem of mismeasurement results. When the user's feet and hands are against the abutting member and the moving member, the output module outputs a command for the user to perform the measuring step according to the instruction; and when the user's feet and/or When the hand does not reach the top member and/or the moving member, the output module outputs a reminder signal to remind the user that the posture is improper, and the posture should be corrected to facilitate the measurement step. And, the measurement result is added by the encryption module. The secret step can avoid the problem of foreign capital leakage.
