Embodiment 1, the user process of use sitting position corrector when reading is:
(1) user employs this sitting position corrector when reading, and after opening switch, charactron can show 0000, buzzing
Device does not has sound；
(2) regulation ultrasound probe institute belt supporting frame, makes the height of probe keep maintaining an equal level with books height, ultrasonic emitting probe and
Receiving transducer is started working, and continuously sends out the ultrasound wave harmless to personage；
(3) photographic head starts simultaneously at work, reads image and passes to singlechip chip, being sentenced by singlechip chip routine processes
Whether disconnected shelter is face；
(4) use a period of time, user can unintentional activity arm once or move books, now photographic head is sentenced
Disconnected shelter is non-face, will not trigger buzzer alarm；
(5) the lowest head of user, instrument by ultrasonic ranging judge shelter and probe distance less than fixed value,
And photographic head identifies face, now singlechip chip triggers buzzer warning, and show on charactron the head of user with
Distance between books.
Embodiment 2, user use the process of sitting position corrector to be when seeing computer:
(1), before user is sitting in computer, sitting position corrector has been hung over after computer by two hooks carried by user,
And spill photographic head, ultrasound probe, on and off switch, buzzer and charactron.Sitting posture is opened by pressing on and off switch
Appliance, now numeral method 0000, buzzer does not has sound；
(2) regulation ultrasound probe institute belt supporting frame, makes probe and books holding level.Ultrasound probe is started working, by sending out
Penetrate and receive ultrasound wave to measure the distance between human body and probe；
(3) photographic head is opened simultaneously, reads the scene irradiated in real time, and image is sent to singlechip chip；
(4) use a period of time, user stand up activity time, photographic head is not detected by face, thus without trigger buzzer report
Alert；
(5) face of user slowly presses close to computer screen, and now photographic head works with ultrasound probe simultaneously, transfers data to
Singlechip chip, singlechip chip processes through calculating, and user is excessively near from computer, and therefore triggering buzzer alerts,
Distance between numeral method user and computer.
This utility model, for pursuing degree of accuracy, is mounted with lifting support for ultrasound probe and photographic head, so can make measuring instrument
Device keeps maintaining an equal level with books and computer, eliminates error.
