At a young age, students are not born with the consciousness and initiative to protect their eyesight and prevent myopia. Even though many parents educate their children and often remind students to raise their heads and keep a healthy eye distance when reading books and doing homework, many students are still reluctant. The eyes are close to the books to read and do homework at a close distance; students have a heavy learning burden, and students spend a long time reading books and doing homework at home. Many students cannot follow parents' reminders or requirements to maintain a healthy eye distance when studying at home. These are Now there are many students suffering from myopia is the main reason. Students spend most of their time in school listening to the teacher's lectures and reading the teacher's writing on the blackboard. The reason why many students suffer from myopia is that students keep their eyes close to the book for a long time when they are studying at home. It is caused by the habit of reading books.

In the prior art, such a sitting posture reminder device sends out an alarm or prompt to remind the student to raise his head or keep his eyes away from the book when it detects that a student who is reading and studying is bowing his head or leaning forward. The sitting posture reminder can be removed casually, or the sitting posture reminder can be turned off, or the detection distance standard can be adjusted to make the detection and reminder of the sitting posture reminder invalid. There is also a type of device where the bracket installed on the corner of the student's desk is pressed against the student's chin or against the student's chest to control the student's head not too low and eyes not close to the book to read and study. This kind of device is very good. It restricts students' eyes from getting too close to the book when studying. However, such devices are unsightly when used, especially as a shackle for children who are studying. Many parents and students psychologically reject such measures to protect eyesight and prevent myopia. , the promotion of such a device has limitations, and it is difficult to use it for a long time in the student life of more than 10 years.

The difference between the technical solution of this embodiment and the sitting posture reminder in the prior art is: 1. The box-type base 10 is fixedly installed on the desktop 6, and the measurement reference of the ultrasonic ranging sensor 2 is reliable; 2.

The student cannot turn off the ultrasonic ranging sensor 2 without authorization 4. Students cannot turn off the alarm or reminder sound issued by the speaker 18 without authorization when studying; 5. Students cannot adjust the detection distance standard without authorization to avoid detection and supervision. Incorrect sitting posture or students' eyes too close to the book when studying is an unhealthy eye-use habit for students. Generally speaking, students with such unhealthy eye-use habits will definitely be reminded by teachers and/or parents. However, such students often do not have the persevering determination to correct unhealthy eye habits and cannot put it into practice to implement healthy eye learning every day. This is the deep-seated reason why some students' eyes gradually suffer from myopia. The technical solution strengthens the monitoring and supervision of students' healthy eyes during learning. Most of the students are in a very fixed position when they study at home. Such a desktop device with a lock to protect eyesight is compared to the sitting posture reminder. The device can reliably replace the parents urging the students to protect their eyesight and prevent myopia. Compared with the students, the parents are patient, scientific, tenacious, principled, and can remind the method of diversification. For example, at the beginning, the detection distance standard of the ultrasonic ranging sensor 2 can be adjusted to slightly improve the requirements for healthy eyes, and at the same time, the harsh noise from the loudspeaker 18 can be adjusted so that the students have to correct the unhealthy Using eyes to focus on learning, students just lift their heads a little bit to make the harsh noise disappear immediately, and students can do their homework with peace of mind. Such a student learns the use of a desktop device with a lock to protect eyesight Few students disobey; for example, the speaker 18 can be adjusted to remind the parents of the students or the teacher's dignified language prompt recording, so that the students feel that the teachers and parents are beside them to supervise them; It is adjusted that the loudspeaker 18 sends out a reminder with pleasant music, so that students can learn with their eyes in a happy and healthy way.

The technical solution of this embodiment is the use of a desktop device with a lock for students to learn to protect their eyesight, and solves the problem that students are young and lack the consciousness and initiative to protect their eyesight and prevent myopia, and the key 14 is controlled in the students. In the hands of the parents, it effectively prevents naughty students from moving the cassette base 10 without authorization, changing the detection distance standard, turning off the detection of the ultrasonic ranging sensor 2, turning off the speaker 18 to sound an alarm or a reminder, and monitoring, urging The measures of students' healthy eye-learning have been put into practice, and the implementation effect is good.

Students are young, and students are not born with the consciousness to protect their eyesight and prevent myopia. Even though many parents educate their children and often remind students to raise their heads and keep a healthy eye distance when reading books and doing homework, many students still have long eyes. Time to read books and do homework at close range; students have a heavy learning burden, students spend a long time reading books and doing homework at home, and many students cannot follow parents' reminders or requirements to keep a healthy eye distance when studying at home. These are the reasons why many students today The main cause of myopia.

The existing technology has such a sitting posture reminder device that sends out an alarm or prompt to remind the student to raise his head or keep his eyes away from the book when it detects that the student's head is lowered or the body is leaning forward. However, many students are naughty and resist this. The students can move the sitting posture reminder casually, or turn off the ultrasonic ranging sensor 2 or adjust the detection distance standard to make the detection invalid.

The difference between the technical solution of this embodiment and the prior art sitting posture reminder is: 1. The box base 10 is fixedly installed on the desktop 6, and the ultrasonic distance measuring sensor 2 has a reliable measurement reference; 2.

The students cannot move the box base 10 without permission, and the students cannot escape the detection of the ultrasonic ranging sensor 2 when they study; 3. The students cannot close the box without authorization. Detection of ultrasonic ranging sensor 2; 4. Students cannot turn off the alarm or reminder issued by the speaker 18 without permission when they are studying; 5. Students cannot adjust the detection distance standard without permission to avoid detection and supervision. Improper sitting posture or students studying with their eyes close to books are unhealthy eye habits. Most of these students are reminded by teachers and/or parents when they study, but these students do not have the persistent determination to correct unhealthy eye habits And can not put into practice the practical action of changing unhealthy eye habits every day, this is the deep-seated reason why some students' eyes gradually become myopic. The technical solution of this embodiment strengthens the monitoring and supervision of students' healthy eyes when they study. Most of the students are in very fixed positions when they study at home. In this way, the method of using the desktop device with a lock to protect eyesight makes a A desktop device with a lock to protect eyesight replaces the parents to urge the students to learn to protect eyesight and prevent myopia. Compared with the students, the parents are patient, scientific, tenacious, principled, and can remind the methods of diversification and humanity. change. For example, when using a desktop device with a lock at the beginning, the detection distance standard of the ultrasonic ranging sensor 2 is adjusted to slightly increase the requirements for healthy eyes, and at the same time, the harsh noise from the speaker 18 is adjusted to make students feel uneasy The students have to obey. As long as the students raise their heads a little, the harsh noise will disappear immediately, and the students can do their homework with peace of mind; It is the recording of the dignified language prompts from the parents of the students or the teachers, so that the students feel that the teachers or parents are supervising them. Students are happy and healthy to study with their eyes. A desktop device with a lock for student learning to protect eyesight and a method for using it promote students to change their unhealthy eye habits when they study, and promote the students' eyes to keep their eyes away from books to read and study.

The technical solution of this embodiment specifically solves the problem that students are young and lacks the consciousness and initiative of protecting eyesight and preventing myopia, and implements the measures of urging students to study with eyes healthily, and the implementation effect is good.

Optionally, or both the transmitter and the receiver of the ultrasonic ranging sensor 2 protrude out of the box-type base 10 through the hole opened on the box-type base 10 shell for detection; the sound of the speaker 18 It is also smoothly outputted to the outside of the box-type base 10 through the holes opened on the box-type base 10 .

The base 10 is fixedly installed on the desktop 6 and cannot be adjusted or turned off by the speaker 18 to prompt the students to keep their eyes away from the book or the desktop 6 . According to the technical solution of this embodiment, the student must receive the detection and supervision of whether the camera 17 and the speaker 18 connected to the single chip 15 are healthy or not during the study time. The healthy eye height positioning standard stored in the single-chip microcomputer 15 and the alarm or reminder sound issued by adjusting the speaker 18 are either harsh noises or serious language sounds or gentle voice sounds or pleasant to the ear. Music, the parents or teachers of the students effectively train the students to develop a good habit of using eyes for health, so that the students can protect their eyesight and prevent myopia.

Compared with the technical solution of the student sitting posture reminder, the technical solution of this embodiment has mandatory constraints on student detection and alarm or reminder, aiming at the lack of consciousness and initiative of protecting eyesight and preventing myopia for young students, and avoiding naughty classmates. The detection and supervision failure caused by resistance to detection and resistance to reminders, a desktop device and method for students to learn to protect eyesight with a lock have good implementation effects.

Optionally, the daily startup and shutdown of the lockable desktop device can be selected from the following solutions: 1. When the device is turned on for a long time, no switch exposed outside the casing of the box base 10 can be operated. Shut down, even if the student unplugs the power cord and tries to turn off the detection of the camera 17, because the battery 9 continues to provide power, and after the student goes to school, the parent will continue to plug in the power cord to the The battery 9 is charged; 2. The student's parents use the key 14 to open the lock 13 to open the door 11 to turn on or off; or the parent unplugs the power cord and pulls out the battery 9 to realize the shutdown; 3. There is an electronic clock in the desktop device with a lock, and the The program of the single-chip microcomputer 15 is set to turn on or off according to the time of the electronic clock; 4. The parents of the students use their mobile phones to connect the Internet access module to access the single-chip microcomputer 15 to turn on or off the single-chip computer 15; 5. Set the program of the single-chip microcomputer 15 to control the camera 17 Interval time to detect whether there are students sitting in the position to study, detect that there are students turning on when they are studying, and detect that no students are turning off or sleeping when they are studying.

Now the proportion of students suffering from myopia is very high. It is not because parents or teachers did not find and remind them, nor did they have no tools to guide or remind students to keep their eyes at a healthy distance from books. The brackets on the corners and under the chin or on the chest are a good tool to prevent myopia in the eyes of students. It is low-cost, simple and applicable. After insisting on using it, the effect of preventing myopia in students is very good, but it is difficult to promote the use in practice. The reason is that such an application scenario seems to be using a shackle to bind children to study. Many students and their parents are psychologically difficult to accept such a state, and it is difficult to persevere for a long time to allow children to study in such a scenario. For another example, there is also a sitting posture reminder device for students to study while reading, which can prompt the students with sound or light in time when their eyes are too close to the book. Good; the reason is that the students are young, students are not born with the consciousness to protect their eyesight and prevent myopia, some students are naughty, and some students will do everything possible to resist detection and reminders, and the sitting posture reminder device for students to read and study is in Students who resist so much lose the effect of forcing them to change their unhealthy eye-use study habits.

Most of the students who gradually develop myopia are because they have developed the unhealthy habit of using their eyes to read books or homework books, just through the education of the students' parents or teachers, or just by providing the students with a sitting posture reminder It is very difficult for students to change their unhealthy eye-use habits to study. The technical solution of this embodiment is different from the prior art, providing a training tool for parents or teachers to train the students to change their unhealthy eye-use study habits, and providing a method for using such training tools for parents or teachers of students And provide such a training method to change students' unhealthy eye habit of reading and learning. The parents or teachers of the students have goals, plans, steps, and means to compare each time in stages according to the current situation of changes in the students' eyesight or changes in the students' eye habits. The situation at that time slightly improved the requirements of protecting eyesight, preventing myopia, and using healthy eyes to adjust the height positioning standard of the students' learning eyes. For example, at the beginning, according to the current situation of changes in the students' eyesight or the changes in the students' eye habits, the parents or teachers of the students just compared the situation of the students at that time to improve a little bit to protect the eyesight and prevent myopia. The requirement of healthy eyes adjusts the height positioning standard for judging the healthy eyes of the students reading and learning eyes stored in the single-chip microcomputer 15, and simultaneously adjusts the loudspeaker 18 to emit a harsh alarm sound to make the students noisy; At this time, there are two options. One option is to keep reading and studying with an unhealthy eye distance. However, the technical solution of this embodiment makes it impossible for the student to choose this solution because of the continuous piercing alarm sound. The noise makes the student unable to concentrate on completing the homework assigned by the teacher that day; another option is to ask the student to raise his head a little, the screeching alarm sound stops immediately, and the student After obtaining a quiet environment, you can continue to study and successfully complete the homework assigned by the teacher that day. Faced with such a situation, almost 100% of the students will choose to raise their heads slightly. The technical scheme of training students to change their unhealthy eye-use habit of reading and learning in this example makes students obey the question of whether to change their unhealthy eye-use habit of reading and learning, and every time it improves a little bit to protect their eyesight and prevent myopia The requirements of healthy eyes adjust the height positioning standard of the students' eyes to judge the health of the students' reading and learning eyes, which is stored in the single-chip microcomputer 15. The daunting task of eye habituation is accomplished through repeated, repeated, repeated, long-lasting, only minor improvements each time, with a locked tabletop tool, with a single training method. , to achieve the goal of protecting students' eyesight and preventing students' myopia. In the course of this training, the parents or teachers make the students gradually change the unhealthy habit of studying with eyes, and the parents of the students train the students to gradually develop the habit of protecting eyesight, preventing myopia and healthy studying with eyes , until the student has changed the unhealthy habit of studying with eyes and has developed the habit of studying at a distance of healthy eyes; the parents or teachers of the students can also assist the students with pseudo-myopia by exercising their eyes at the same time. The students recover their eyesight, and for students whose myopia is irreversible, they can wear glasses on the premise that their vision has been stabilized and continue to use a desktop device and method with a lock to protect the eyesight to cultivate and consolidate the students' healthy eyes. The habit of studying makes such students' eyesight no longer deteriorate and avoid deep myopia. Implementing the technical solution of this embodiment can achieve the goal of protecting students' eyesight and preventing myopia, and the process of implementing the technical solution of this embodiment conforms to the doctrine of behavioral science.

Students' acquired myopia is mainly caused by the unhealthy habit of using eyes when they are studying, and the students' unhealthy eye habits include poor light in the learning environment, inability to insist on doing eye exercises to exercise their eyes, and others. Proper rest time cannot be arranged during long-term study, which makes the adjustment function of the nerves and muscles of the eye organs decline. Among these factors, the habit of reading and doing homework by keeping the eyes close to books for a long time is the most harmful when students study at home. . The prior art prominently proposes some technical solutions for monitoring and urging the students to keep their eyes away from the book or homework while reading and doing homework when their eyes are close to books or homework for a long time while studying at home. However, the current situation is that more and more students are suffering from myopia and a large area of students in schools are suffering from myopia, which directly affects the supply of eye health labor and the supply of cutting-edge technical talents. Under the circumstances that parents attach importance to reminders, teachers strengthen education, and the supply of some devices to protect eyesight and prevent myopia is becoming more and more abundant, why are more and more students still suffering from myopia? What are the deep-seated reasons? How to break the game is a social phenomenon that triggers our further research and innovation. We realize that: ① It is not a problem of lack of reminders for students, and it is not a problem that can be solved by increasing the supply of products like sitting posture reminders; ② We are facing the development of technology, knowledge explosion, and students' academic burden. The reversal is increasingly heavy, and it is impossible to solve this problem by reducing the burden; 3. The students are young, and they are born without the consciousness and initiative to protect their eyesight and prevent myopia; 4. The students are naughty, and the students have the ability to resist monitoring and urge them to keep their eyes healthy. The urge to learn; ⑤Students do not have the persistent determination to change their unhealthy habit of studying with their eyes. Based on the above knowledge, the technical solution of the present application is to provide a training tool for parents or teachers to train the study to change unhealthy eye-use study habits, and to provide parents or teachers with a desktop device that protects eyesight and has a lock method, and provide a training method for students' parents or teachers to train the said study to change the unhealthy eye-use study habits, among the students, students' parents and teachers, teachers strengthen professional education and promote and help students' parents stand To solve this problem, there are goals, plans, steps, and means to train the students to change the unhealthy habit of studying with eyes, and cultivate the students to gradually develop the habit of studying with eyes in a healthy way, so that the students can learn with their eyes. Students achieve the desired goal of protecting eyesight and preventing myopia.

The technical solution of the present application is not available in the prior art, and has practicability, novelty and creativity.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent substitutions can be made without departing from the spirit and scope of the technical solutions of the present invention.
