The following description is provided with reference to fig. 4, the working principle of the intelligent posture-correcting double-backboard learning chair is as follows:
when the intelligent voice posture correction system is used, the seat assembly 4 is adjusted to be proper in height, depth and distance from a table, and when the power switch 701 is turned on, the intelligent voice posture correction system starts to work.
1. When the child is in the correct sitting posture
At this time, the back of the child is tightly attached to the central portions of the left back plate assembly 31 and the right back plate assembly 32, and the left back plate assembly 31 and the right back plate assembly 32 are in a balanced state. The transmitting end and the receiving end of the obstacle avoidance module 718 installed in the left back plate assembly 31 are both opposite to the inner side edge of the back middle plate of the right back plate assembly 32 through the elongated holes on the inner side edge of the back middle plate of the left back plate assembly 31. The infrared rays emitted by the emitting end of the obstacle avoidance module 718 are reflected by the middle plate of the chair back of the right back plate assembly 32 to the receiving end of the obstacle avoidance module 718, and the obstacle avoidance module 718 outputs a low-level signal and cannot trigger the relay module B716 electrically connected with the low-level signal to conduct and work.
Meanwhile, when the child is in a correct sitting position, the body part of the child cannot touch any one of the 4 pulse arm sensors, and no signal is output from the 4 pulse arm sensors.
Therefore, when the child is in a correct sitting posture state, the intelligent voice posture correcting system cannot send out a warning voice for correcting the sitting posture.
2. When the child has incorrect sitting posture (left or right inclination)
When the child is badly seated and has a left or right inclination, the left backboard assembly 31 and the right backboard assembly 32 are dislocated and deformed due to unbalanced stress. Infrared rays emitted by an emitting end of the obstacle avoidance module 718 cannot be reflected back to a receiving end of the obstacle avoidance module 718, the obstacle avoidance module 718 outputs a high level signal to trigger a relay module B716 electrically connected with the obstacle avoidance module to conduct and work, a voice recording and broadcasting module 713, a power amplifier module 709 and a relay module C707 arranged in the right chair back assembly 32 are electrified and work, so that the relay module C707 obtains the high level signal, the relay module C707 is designed to be triggered at the high level and conducted immediately, the relay module C707 is contacted effectively again during conduction, and when the relay module C707 is conducted, the generated high level signal also synchronously triggers the time relay module B708 to conduct and work; when the time relay module B708 is turned on by a high level signal, the voice recording and broadcasting module 713 works for a time T, that is, the speaker 710 repeatedly broadcasts voice times like "kids, please correct sitting posture", "correct sitting posture is good and study", and the like; when the sitting posture of the child is recovered, the obstacle avoidance module 718 outputs a low level signal, the relay module B716 electrically connected with the obstacle avoidance module cannot be triggered to be switched on, the power supply cannot be transmitted to each electronic component in the right chair back assembly 32, and the voice playing is stopped.
Meanwhile, when the child has a bad sitting posture and has a left or right inclination, the body part touches any one of the 4 pulse arm sensors, the output port of the touched pulse arm sensor outputs a pulse-charging type high-level signal, and the relay module C707 or the relay module A715 connected with the pulse arm sensor is triggered to be conducted. For example:
when a body part of a child touches any one of the pulse arm sensor A703 or the pulse arm sensor A704, the output port of the pulse arm sensor outputs a pulse-filling high-level signal to trigger the relay module A715 which is continuous with the pulse arm sensor to be conducted; since the normally open end of the relay module a 715 is electrically connected to the positive terminal port of the battery assembly 717, the common end of the relay module a 715 is electrically connected to the ground end of the time relay module a 714; the relay module a 715 is designed to be triggered at a high level and immediately turned on, and is again active during the on period.
Since the common end and the normally open end of the time relay module a 714 are connected to the common end and the normally open end of the time relay module B708 through the audio line L4 and the audio line L5, respectively, when the relay module a 715 is turned on, the audio line L4 and the audio line L5 are turned on and connected to generate a trigger high level signal for the time relay module B708, and the time relay module B708 is turned on for T time.
Because the power amplifier module 709 is connected with the public end of the time relay module B708 through the audio line L2, the time relay module B708 is connected with the loudspeaker 710 through the audio line L3, when the time relay module B708 is also conducted after obtaining a high level signal, the voice recording and broadcasting module 713 works for T time, and the loudspeaker 710 repeatedly broadcasts warning voice T time like 'children, please correct sitting posture', 'correct sitting posture and good learning' and the like; when the sitting posture of the child is recovered, the output of the pulse arm sensor A703 or the pulse arm sensor A704 is a low level signal, the relay module A715 stops conducting, the time relay module B708 has no trigger signal, and the voice playing of the loudspeaker 710 stops.
Similarly, when the body part of the child touches any one of the pulse arm sensor C705 or the pulse arm sensor D706, the time relay module B708 obtains the high level signal conduction, the voice recording and playing module 713 works for T time, and the speaker 710 repeatedly plays warning voice T time like "kids, please correct sitting posture", "correct sitting posture is good to learn", and the like; when the sitting posture of the child is recovered, the output of the pulse arm sensor A703 or the pulse arm sensor A704 is a low level signal, the relay module A715 stops conducting, the time relay module B708 has no trigger signal, and the voice playing of the loudspeaker 710 stops.
The foregoing shows and describes the basic principles, features and technical effects of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and the scope of the invention is to be protected. The scope of the invention is defined by the claims and their equivalents.
