Background technology

Myopia is the teen-age common disease in China.Shown according to relevant data：In China, 10% to 20% new primary students suffer from Myopia；Rate of myopia when pupil graduates is about 50%；The rate of myopia of entrant is about 90%, is much higher than US and European. Serious threat has arrived the national holistic health level in China for this.The main reason for causing adolescent myopia is incorrect reading Write posture.Teenager is in growth and development stage, and many organs are not all reached maturity also including eyes, easily produces distortion. Due to heavy lessons pressure, teenager is very long between using at the moment daily, and eyes are easily tired, if not keeping correctly reading and writing Posture, eyes are excessively near from books, will aggravate the burden of eyes, so as to induce myopia.And present smart mobile phone, tablet personal computer etc. Amusement equipment emerge in an endless stream, and have even more aggravated this trend.

For pre- myopia prevention, people come up with thousand and one way.Most commonly seen method is exactly with the pre- myopia prevention of auxiliary equipment. The pre- myopic-preventing auxiliary equipment occurred now is broadly divided into following two according to operation principle：1st, it is mechanically fixed asana.2、 Sensor is visited away from method.It is exactly that human body is fixed on a certain position using devices such as support, belts to be mechanically fixed asana, so as to protect Hold correct read-write posture.Such as a kind of Support for preventing myopia, desktop edge is fixed on during use, and pedestal upper end has a crossbeam, horizontal Beam is away from desktop distance 30cm.Chin is placed on crossbeam during use, the distance of eyes to books will one when writing on the table Such a safe distances of more than 30cm directly are maintained at, so as to pre- myopia prevention.The advantages of this kind equipment is simple in construction, effect Substantially, shortcoming is can only to be used in fixed location, and installation and removal are all cumbersome.It is exactly to consolidate in Head And Face that sensor, which is visited away from method, A fixed device for carrying range sensor, the distance of eyes and objects in front is detected by range sensor, works as hypotelorism When send alarm sounds user's correcting sitting postures.Common way is that range sensor is integrated in head hoop or frame, is led to Cross constantly measurement objects in front and judge whether user maintains enough distances with eye to the distance of equipment, when apart from mistake Send that alarm and reminding user keeps fit when near with eye distance from.The advantages of this kind equipment is small volume, is easy to carry with. Shortcoming is that accuracy is poor and wearing comfort is bad.Because range sensor is that all objects in front are carried out Detection, any object in front of equipment are likely to trigger alarm, such as hair, pen etc..And this can not reflect real use Eye situation.Further, since eyes are rotary, so the direction of sight is possible to the direction with sensor detection and differed Cause.Such as people, when writing on the table, head and eyes all rotate down, and the direction on head and the direction of sight are not consistent, In the presence of an angle.This distance for being possible to cause to measure objects in front in cephalad direction is more than safe Writing distance, and Eyes to target actual range already less than safe Writing distance.So this kind equipment knowledge with eye situation actual to user Other accuracy is poor.And in order to prevent head from adjusting the distance the obstruction of sensor, this kind equipment must be worn on face, and this is just doomed It can only use the form of head hoop or glasses, and most people are without the custom for wearing head hoop, without near-sighted people's pendant Wearing glasses can also feel uncomfortable, therefore wearing comfort is bad.

The content of the invention

The technical problems to be solved in the utility model is：The pre- myopic-preventing portable devices of tradition are bad, and accuracy is not high, The problem of wearing comfort is poor.

In order to solve the above-mentioned technical problem, a technical scheme of the utility model use is：Design one kind can prevent near Depending on wearable device, worn part by wearing part and hand and formed, head and the hand of human body are separately fixed at during use, is worn Range sensor, single-chip microcomputer, battery built in part, hand wear range sensor built in part, single-chip microcomputer, attention device, battery, equipment The distance of head and hand is measured by range sensor, and is compared with built-in preset data, when the data measured and in advance If data are not inconsistent, single-chip microcomputer control attention device sends alarm signal.

Wherein, equipment profile is designed as the profile for meeting the daily wearing custom of people.For example, the profile for wearing part can be with It is designed as hair clip, ear-hang, earrings, head hoop, headband, glasses etc..Hand wear part profile can be designed as bracelet, ring, wrist-watch, Bracelet etc..

Wherein, it is transmitter to wear the range sensor one that part and hand are worn built in part, and one is receiver.Signal Send and be received by the receiver from transmitter, so as to realize precision ranging between the two, and exclude approaching object interference.

Wherein, the signal of range sensor transmitting makes receiver only receive same complete equipment using coding or other modes The signal that transmitter is sent, to prevent from closing on the interference of same category of device.

The beneficial effects of the utility model are：1st, good portability.Equipment is designed as wearable device, improves equipment Portability.It can whenever and wherever possible play a role, adapt to plurality of application scenes, such as read, write, using handheld electronics device.

2nd, accuracy is high.Closely with eye activity, eyes range-to-gos is in fact all in most cases It is the distance between eyes and hand.During writing, eyes are to stare at the pen in hand always.During reading, eyes are stared in hand and taken always Book.When playing mobile phone, eyes stare at the mobile phone in hand.So the distance between eye and hand can accurately reflect close eye feelings Eyes range-to-go under condition.In addition, the design of range sensor transmitter and receiver can also exclude other objects Interference, accurately measure distance between the two.To the coding of transmission signal, it can prevent from closing on the interference of same category of device.
