The detection direction of the distance detector 102 is a direction away from the upper surface of the ruler body 101.

It should be noted that the preset distance value is determined according to the distance from the eyes to the reading material in the correct sitting posture, if the distance from the eyes to the reading material is 30cm in the normal sitting posture, the preset distance value may be set to 30cm, and when the detected distance is less than 30cm, it indicates that the eyes are too close to the reading material, the control unit 104 may send a control signal to the reminding unit 103, and the reminding unit 103 may perform a reminding action, such as sending out a reminding signal in the form of sound, light, vibration, and the like, to remind the using pupils to adjust the sitting posture of the pupils.

According to the embodiment, the ruler used by the pupils in daily life is combined with the sitting posture detection device, so that the pupils do not need to additionally carry the sitting posture detection device, and inconvenience caused by additionally adding the sitting posture detection device is avoided.

Optionally, the distance detecting unit 102 includes: an ultrasonic distance detection module and/or an infrared distance detection module.

The ultrasonic distance detection module is a sensor developed by using the characteristics of ultrasonic waves. The ultrasonic wave is a mechanical wave with vibration frequency higher than that of sound wave, is generated by the vibration of a transduction wafer under the excitation of voltage, and has the characteristics of high frequency, short wavelength, small diffraction phenomenon, good directivity, directional propagation as rays and the like.

It should be noted that the infrared distance detection module is a measurement system using infrared as a medium, and has a pair of infrared signal emitting and receiving diodes, which emits a beam of infrared light, forms a reflection process after the infrared light irradiates an object, receives the signal after the infrared light is reflected to a sensor, and then receives data of a time difference between the emission and the reception by using an image sensor.

Optionally, as shown in fig. 2 to 3, the ruler further includes: a reflector 201 rotatably connected to the ruler body 101; the detection direction of the infrared distance detection module faces the reflector 201. In practical use, when the ruler is placed at different positions relative to a user, the detection directions of the infrared distance detection modules are different, and therefore, the detection directions of the infrared distance detection modules need to be adjusted correspondingly. However, if the infrared transmitting terminal and the receiving terminal of the infrared distance detecting module are made to be rotatable, the structure corresponding to the infrared distance detecting module is too complicated, and frequent rotation may cause damage to the communication line of the infrared distance detecting module. Therefore, in the above embodiment, a rotatable reflector 201 and an infrared distance detection module are provided, the infrared detection light 301 is emitted onto the reflector 201, the reflector 201 emits the infrared detection light 301 onto the reflector 201, the reflector 201 reflects the infrared detection light 301 to a target detection direction, after the infrared detection light 301 hits on a target (such as a human face), the infrared light is reflected, and after the reflected feedback infrared light 302 irradiates on the reflector 201, the reflector 201 reflects the feedback infrared light 302 to a receiving end of the infrared distance detection module. Thus, the detection direction of the infrared distance detection module can be adjusted by rotating the reflector 201, so as to adapt to different detection angles corresponding to different positions of the ruler.

Optionally, the ruler further comprises: and the adjusting button is in communication connection with the control part and is used for adjusting the size of the preset distance value.

It should be noted that, because the distances from the measured object at the same position to the ruler are different at different detection angles, different detection angles need to correspond to different preset distance values. If the ruler is placed under the head of a student and the infrared distance detection module faces upwards for detection, the distance from the head of the student to the ruler should be greater than 20cm when the ruler is in a correct sitting position, and if the ruler is placed in front of a book of the student on a desktop, the infrared distance detection module needs to detect at an upward inclination angle of about 30 degrees relative to the horizontal plane, and the distance from the head of the student to the ruler should be greater than 40cm when the ruler is in a correct sitting position. The above-mentioned adjustment button is therefore required to adjust the preset distance value. So that the ruler can be judged at different positions according to different preset distance values.

Optionally, a groove 202 is formed in the ruler body, and the transmitting end and the receiving end of the infrared distance detection module and the reflector are disposed in the groove 202.

It should be noted that, if the emitting end, the receiving end and the reflector of the infrared distance detection module are arranged on the surface of the ruler, the surface of the ruler has a large protruding structure, which affects the normal use of the ruler, and meanwhile, the infrared distance detection module is easily damaged due to collision of the infrared distance detection module protruding out of the surface of the ruler. Therefore, the infrared distance detecting module is embedded in the ruler, and the emitting end and the receiving end thereof are exposed through the groove 202.

Optionally, the reminding portion 103 includes at least one of: the sound-emitting reminding module, the light-emitting reminding module 303 and the vibration reminding module.

The sounding reminding module can be a buzzer or a loudspeaker; the light-emitting reminding module can be an LED lamp bead, a lamp strip and the like, and can also be an LED display screen; the vibration reminding module can be a vibration motor.

Optionally, as shown in fig. 4, the ruler body 101 includes a ruler body portion 401 and a scale portion 402, the scale portion 402 is made of a light-transmitting material, and the scale portion 402 is connected to a side surface of the ruler body portion 401; the light-emitting reminding module 403 is arranged on the side surface of the ruler body part 401 connected with the scale part 402, and the light-emitting direction of the light-emitting reminding module 403 faces the scale part 402.

Optionally, the ruler further comprises: an on-off button for controlling the turning on and off of at least one of: the device comprises a sounding reminding module, a luminous reminding module and a vibration reminding module.

It should be noted that, because the ruler is frequently used when the student goes to learn in daily class, in a quiet environment in a classroom, it is not suitable for reminding through the sounding reminding module or reminding through the vibration reminding module in order not to affect other students, so that in order to adapt to the scene, the luminous reminding module 403 may be only arranged in the reminding part 103, or arranged on a switch corresponding to the occurrence reminding module and the vibration reminding module. Further, if the light-emitting reminding module 403 directly emits strong reminding light into the air, it will also affect other classmates in the classroom, so in the above embodiment, the scale portion 402 is provided with a transparent material, which can be plastic, resin, or other material that can both transmit light and scatter light. The light-emitting reminding module 403 is arranged in front of the ruler body part 401 and the scale part 402, and the emitted light rays are firstly transmitted into the scale part 402, scattered in the scale part 402 and then emitted out of the scale part 402. The scheme avoids the influence of stronger reminding light on surrounding people. In order to improve the reminding effect, the light-emitting reminding module 403 can remind in a flashing manner.

Optionally, the light-emitting reminding module 403 includes a plurality of light-emitting devices with different light-emitting colors. The above embodiment further enhances the reminding effect of the light-emitting reminding module 403.
