Intelligent head-wearing eyesight protection instrument

Abstract

The invention discloses an intelligent head-wearing eyesight protection instrument which comprises a sensor, a controller and an alarming device. The sensor is used for measuring distance, light intensity or dip angle, wherein the distance is measured by an infrared PSD (position sensitive detector), infrared TOF (time of flight) or a laser measurement unit, the light intensity is measured by the aid of a photosensitive sensor, and the dip angle is measured by the aid of a gravity accelerometer or a gyroscope. The controller is used for receiving corresponding data measured by the sensor and comparing the corresponding data with a set value according to measured results, and the alarming device is triggered to send an alarm if the data exceed a set range. The alarming device is used for alarming according to control commands of the controller. The intelligent head-wearing eyesight protection instrument has the advantages that a user is helped to develop a fine learning posture by means of monitoring the learning posture of the user so as to effectively protect eyesight.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a head-mounted intelligent vision protector. Users can use this product in the process of learning to maintain correct learning postures and develop habits, effectively preventing teenagers from Myopia problems caused by bad sitting posture, poor light environment, and too long study time. Background technique [0002] 1. In the current information society, more than 80% of human beings obtain external information through vision. The data shows that the prevalence of myopia in our country is about 33%, that is to say, 400 million people are myopia. What is even more concerning is that there are about 30 million people in China with pathological myopia above 600 degrees and accompanied by fundus changes. Such myopia may be complicated by retinal detachment, glaucoma, and core cataract. At the same time, strabismus and amblyopia among teenagers have become a major problem th...

Problems solved by technology

[0003] 2. More and more primary and middle school students study for too long due to excessive homework and do not pay attention to eye rest. Incorrect sitting posture is also the main cause of myopia.

[0004] 3. Some current inventions, such as CN97221900.5 "Electronic Eyesight Protector", CN99210689.3 "Multifunctional Eyesight Protection Desk Lamp Special for Students", etc., cannot detect the tilt angle of the head, and cannot perform scientific calculations and Allocate study and rest time, and use photoresistors to accurately detect the current light intensity
