[0002] Teenagers are in the growth and development stage and have a relatively heavy workload. Sitting on a stool for a long time to write has a significant impact on their vision and development. Specifically, long reading and writing time can easily lead to poor vision and adverse effects on joints such as the lumbar spine. Therefore, preventing teenagers from sitting for a long time is an important means to ensure their vision and physical health.

[0003] In the prior art, there is no device that can count the time teenagers spend sitting on stools at home, and it cannot remind them to get up from the stools for exercise in the corresponding time period. Generally, teenagers get up from the stools for physical exercise at regular intervals. This method relies entirely on the teenagers to take the initiative to exercise. In reality, not every teenager has good self-discipline, and when they forget to get up from the stools for exercise while reading and writing, it will have an adverse effect on their eyesight and physical health. In summary, it is particularly necessary to provide a monitoring and prompting device that can actively accumulate and count the time teenagers spend sitting on stools for writing, and can actively remind them to get up from the stools for exercise when a time period threshold is set.

When the user sits on the stool for a period exceeding the set time, it can automatically remind the user to get up from the stool for exercise, and when the user fails to exercise within the set time for multiple times, it can notify the parents by text message to supervise them. This can provide a relatively good protective effect on the eyesight and physical health of teenagers.

[0007] Furthermore, the lower end of the blocking block contacts the upper end force-bearing surface of the pressure sensor.

The trigger circuit includes a time relay module A4, a resistor R3, and a transistor Q4 connected via circuit board wiring. The negative power input terminal 2 and the negative trigger signal input terminal 4 of the time relay module A4 are connected to the emitter of the transistor Q2. The output terminal 5 of the time relay module A4 is connected to one end of the resistor R3. The other end of the resistor R3 is connected to the base of the transistor Q1.

[0017] Figure 1 , 2As shown in the figure, the two poles of the battery G1 and the two ends of the charging socket CZ are connected by wires respectively (when the battery G1 is out of power, the external 12V power charger plug can be inserted into the charging socket to charge the battery. The socket of the charging socket and the power switch handle are located at the right outer end of the component box), and are connected in series with the power input terminals 1 and 2 of the SMS module A3, the power input terminal of the detection circuit, the positive power input terminal of the relay J1 and the emitter of the transistor Q1, the power input terminal of the timing circuit, the 1 and 2 feet of the time relay module A1, and the power input terminal of the trigger circuit, the 1 and 2 feet of the time relay module A4.

[0018] Figure 1 , 2As shown in , the utility model can conveniently detect whether teenagers are sitting still on the stool for a long time by placing a cushion on the stool. After turning on the power switch S1, all circuits are powered on and work. When no one is sitting on the stool, the force-bearing surface of the pressure sensor RT is not stressed, its resistance value is relatively large, and the voltage divided between it and the resistor R1 is large. In this way, the 12V power supply is divided by the pressure sensor RT and the resistor R1, and the resistor R2 reduces the voltage and limits the current to enter the base of the transistor Q1 below 0.7V. The transistor Q1 will not be turned on, the relay J1 will not be powered on, and the corresponding timing circuit will not input the trigger signal. When someone sits on the stool, the force-bearing surface of the pressure sensor RT is relatively small in resistance, and the voltage divided between it and the resistor R1 is small. In this way, the 12V power supply is divided by the pressure sensor RT and the resistor R1, and the resistor R2 steps down and limits the current to enter the base of the transistor Q1, which is higher than 0.7V. The transistor Q1 will conduct the collector and output a low level to the negative power input terminal of the relay J1. The relay J1 will be energized to close its control power input terminal and the normally open contact terminal, so that the 3rd pin of the time relay module A1 will be input with a high level trigger signal. The 3rd pin of the time relay module A1 inputs a high level signal, and its 5th pin will output a period of power at a certain interval (for example, 5 seconds of power at an interval of 30 minutes, and the time can be set) to the positive trigger signal input terminal 3rd pin of the time relay module A2 and the positive pole of the diode VD. The high level is unidirectionally conducted through the diode VD to enter the positive power input terminal of the buzzer B. The buzzer B is energized to emit a 5-second sound for the first time to remind the user who has been sitting on the stool for a long time to move in time. After the high level is input to the pin 3 of the time relay module A2, its pin 5 outputs a period of power at a certain interval (for example, it outputs 5 seconds of power at an interval of 30 minutes) to the positive trigger signal input terminal 3 of the time relay module A4 and the positive electrode of the diode VD1. The high level is unidirectionally conducted through the diode VD1 and enters the positive power input terminal of the buzzer B. The buzzer B is energized and emits a 5-second sound for the second time to remind the user who has been sitting on the stool for a long time to move in time. After the high level is input to the pin 3 of the time relay module A4, its pin 5 outputs a period of power at a certain interval (for example, it outputs 5 seconds of power at an interval of 30 minutes, and the time can be set) through the resistor R3 current limiting and voltage reduction to enter the base of the transistor Q2. The transistor Q2 conducts and outputs a low level to the pin 3 of the SMS module A3. Therefore, the SMS module A3 sends a text message in the memory. After the mobile phone of the remote relevant personnel (such as parents) receives the text message, they can understand the situation in the first time. Parents can supervise teenagers through telephone (the telephone reminds them to leave the stool in time to exercise), which can play a relatively good protective role for the eyesight and physical health of teenagers. Figure 2Among them, the relay J1 model is DC12V; the transistors Q1 and Q2 are NPN transistors of model 9013; the sounder B is an active continuous buzzer alarm finished product of model FM12; the battery G1 is a 12V / 20Ah lithium battery; the pressure sensor RT is a resistance strain gauge of model BX120-3AA; the resistance values ​​of resistors R1, R2, and R3 are 10K, 47K, and 47K respectively; the time relay modules A1, A2, and A4 are delay time relay modules of model K1305-V2.1, which have two power input terminals, two trigger signal input terminals, four setting buttons, and one power output terminal. By operating the four setting buttons, the time interval and duration of the power output terminal outputting power after the trigger signal input terminal inputs the trigger signal can be set. The SMS module A3 is a wireless remote mobile phone SMS alarm product of the brand Biyin Technology, model 834 (it has two power input terminals and six signal input terminals. When a low level is input to each signal input terminal, a text message can be sent respectively, and the mobile phone connected to the SMS module can receive text messages, so that parents can know the specific situation at the first time); the diodes VD and VD1 are 1N4007.
