Abstract
A voice reminding and rectifying device for sitting posture comprises an infrared photoelectric switch (10) which is arranged at the lateral side of a reading table at 300mm height away from the surface of the table, infrared ray emitted from said infrared photoelectric switch (10) being horizontally directed to the head of a reader. The output signal end of the switch (10) is connected to an electronic circuit (41) contained in a controlling device (40), and the output signal of the electronic circuit (41) is connected to a voice reminding device by a time-delay circuit. The utility model has no interference in and no harmfulness to the reader. The utility model can detect the distance between eyes of the reader and the book, with accuracy above 1cm, thereby helping to prevent myopia and humpback.
Description
Technical field
The utility model relates to the infrared ray position sensor, particularly utilizes infrared ray position sensing technology for detection position of human body and the device of realizing carrying out voice suggestion.
Background technology
Because of the work and study relation, people read before unavoidably will sitting desk, write.But sitting posture leans forward during because of reading, easily cause the bad attitude of those who read and write's hunchback, and excuse leans forward, the eye distance books too closely cause myopia, this situation to the minor particularly the child cause irreversible injury, thereby people have also taked the certain methods measure, prevent the appearance of this situation, and present way has following several:
1. add a plate washer before desk, leaning forward to prevent those who read and write's head, back in the chin position that props up the those who read and write, prevents bad attitude.
2 hang a pendant on those who read and write's neck, be similar to necklace.On weight, adorn inductive switch, lean forward, send the sound and remind those who read and write's correcting sitting postures with detection those who read and write back, head.
3 adorn a photodetector in desk the place ahead, over against those who read and write's face.Those who read and write's head leans forward, and detector detects facial signal, sends the sound, reminds the those who read and write.
4 wear the same utensil of an earphone in those who read and write's head, load onto the location sensitive switch, and those who read and write's head leans forward, and switch changes and sends the sound, reminds the those who read and write.
First method: head always has some activities during reading and writing, and about as above descending etc., this method causes the those who read and write uncomfortable.
Second method: if the those who read and write only head forward, downwards, inductive switch is difficult for detecting those who read and write's eyes and the near excessively attitude of books, does not have the effect of prompting, if hot day, neck was hung a weight, the those who read and write can be uncomfortable yet.
The third method: because usefulness is photodetector head assembly, detection range is difficult for adjusting, moreover infrared ray might damage reading person's eyes.
The 4th kind of method: head is worn a utensil, and certain weight is arranged, and the those who read and write is uncomfortable, wears and gets also inconvenience of this utensil.
CN85202283 number Chinese utility model patent for another example, the scheme of disclosed " prevention myopia of student and vertebra distortion Sitting posture correcting device " by name, it is the device that is provided with a similar mercury cut-off, wear on human body, when human body tilts, switch conduction, this device sends the suggestion voice sound equipment.As can be seen, only depend on the inclination of mercury cut-off to come whether the monitoring human sitting posture correctly is unilateral.
Summary of the invention
The purpose of this utility model is to propose a kind of read-write sitting posture voice reminder corrector for fear of the deficiencies in the prior art part, the utility model adopts the infrared ray position sensor, infrared ray detects the outstanding position of those who read and write's head from the side, if those who read and write's eye apart from books apart from convergence, shelter from the infrared ray light path, and have signal to return, then this device sends the prompting language.
The utility model is realized by adopting following technical scheme.
