The motor vibration reminding unit 8 and the LED lamp unit 6 are respectively connected with the output end of the central processing unit, and the power supply unit 9 is a rechargeable power supply or a dry battery. The appearance structure diagram is shown as the figure I. The structure diagram of the circuit part is shown as the second drawing.
When the distance between the pen holder and the pen is too small, the infrared detection distance unit 1 generates a signal and inputs the signal to the central processing unit 4. After the central processing unit 4 recognizes, the LED lamp unit 6 is started to prompt, the LED lamp unit 6 flickers, and the flickering frequency of the LED lamp is set to 120 times per minute until the posture is correct.
The LED lamp adopts green, white, red and yellow LED type lamps.
When the light of the writing environment is too strong, that is, under the strong light exceeding 1000LX illumination, the too-strong light monitoring unit 2 sends a signal to the chip processor 4, and after the central processing unit 4 recognizes the signal, the LED lamp unit 6 is started to prompt, and the output signal of the central processing unit 4 is set to enable the LED lamp to flash 120 times per minute. The over-light monitoring unit is positioned at the upper end of the intelligent swing and is connected with the central processing unit 4.
When the light is too weak (i.e., dim light), i.e., weak light below 250LX, the too-low light monitoring unit 3 is activated, and the LED lamp unit 6 gives an indication. The LED lamp is always on, and the LED lamp is not turned off until the light is suitable.
After the manual switch 11 is started, the timing rest monitoring unit 5 starts timing, when the learning time reaches about 45 minutes, the LED lamp unit 6 flickers to prompt the user to have a rest, and the flickering frequency is set to be 80 times per minute.
After the manual switch 11 is started, the LED lamp unit 6 flashes at the rhythm of breathing light at a frequency of 15-25 times per minute for six times. The twinkling of the LED light is helpful for a writer to concentrate on writing and quickly enter a learning state.

In order to reduce energy consumption, energy-saving optimization in a working state is performed, and the infrared detection distance unit 1 detects the infrared detection distance once every 400-800 milliseconds. The over-illumination unit 2 and the under-illumination unit 3 are detected every 400-800 ms. The above arrangement is already built in the central processing unit 4, forms an energy-saving measure in the working state, and the energy-saving effect is very obvious. In practice, the working time of the intelligent ornament is prolonged by 180% -200%.
When the user does not trigger the infrared distance detection unit 1, eye fatigue is likely to occur if the user performs a relatively rapid movement. Since the position movement detection unit 16 monitors that the user's position has changed in a short time, the cpu 4 triggers the LED lamp 6 to blink at a frequency of 100 times per minute. Specifically, the position movement detection unit 16 can be regarded as another set of infrared distance detection devices. But differ in two ways: firstly, the detection distance is larger than that of the infrared distance detection unit 1; secondly, the alarm is not given in a certain distance range, and the alarm is given when the distance exceeds the range, while the infrared distance detection unit 1 is opposite, namely the alarm is given when the distance is closer, and the alarm is not given when the distance exceeds the certain distance range. As shown in figure three. In the figure, the dotted line is the boundary line of the detection range, and the solid line is an example of the movement path of the user. When the user goes out of the range shown by the dotted line, i.e., crosses the intersection a or B of the solid line and the dotted line, the position movement detection unit 16 sends a signal to the central processing unit 4, and the central processing unit 4 has the storage unit 4-1, and can perform recording. And analyzing according to the recorded data, and triggering the LED lamp unit 6 and the motor vibration unit 8 to remind when the interval time between two times of recording is found to be less than 1-5 seconds, wherein the flashing frequency of the LED unit is 100 times per minute.
When the learning posture correcting device is used, the front face of the swing part faces a user, and the user adopts a correct learning posture. After the machine is started, the motor and driving wheel unit 8 starts to work, if the swing part is more than 40CM away from the user, the swing part moves to the learner, at the moment, the infrared distance detection unit 1 starts, when the swing part is about 20-40 CM away from the user, an alarm signal is still generated and transmitted to the central processing unit 4, and then the central processing unit 4 commands the motor and driving wheel unit 8 to retreat 1-3 CM away from the swing part and stop, namely, the swing part is in a proper position. When the distance between the swing part and the user is less than 20-40 CM, the motor and driving wheel unit 8 is retreated by 1-3 CM, and then the detection is carried out again, if the distance is still less than 20-40 CM. It continues to back 1-3 CM until proper. After 10 seconds from the distance determination, the infrared distance detection unit 1 will continue normal monitoring. The motor and drive wheel unit 8 can refer to fig. five.
