Technical Field

The invention relates to the field of sensors, and artificial intelligence algorithm-based equipment and an active control method.

Background

In recent years, due to the popularization of electronic products such as mobile phones and computers, factors such as increased burden inside and outside primary schools, and unscientific use of eyes, the myopia rate of children and teenagers is continuously increased, statistics shows that the myopia rate of primary schools exceeds 38%, the myopia rate of juniors and students exceeds 60%, the myopia rate of senior high school students exceeds 70%, and in order to realize myopia prevention and control, the state brings the myopia rate of young schools into government examination. Therefore, the eye is scientifically protected by some technical means, and the myopia generation or the myopia deepening is effectively intervened, so that the method is a social thing and is beneficial to the healthy growth of teenagers.

The existing ultrasonic distance detection method has the problems that the detection of the eye using state of a glasses wearer is inaccurate, the sound and vibration reminding is easy to be ignored by the glasses wearer and continuously keeps wrong eye using state, and the sound or vibration is easy to influence other people in a quiet reading environment and limits the use of the glasses. Meanwhile, the current technical scheme is stopped at simple distance judgment, error judgment is easy to generate, consideration on eye use time, light intensity and the like is lacked, and the purpose of really ensuring eye use health cannot be achieved in effect. In addition, the normal phase atomization membrane used in the current design is opaque in a non-electrified state, if the normal phase atomization membrane is transparent for a long time, the normal phase atomization membrane needs to be electrified all the time, and a large-capacity battery needs to be equipped, so that the product is heavy, and the requirements of portability and wearing comfort cannot be met.

Disclosure of Invention

In order to meet the comprehensive requirements of practicability, accuracy, portability, safety and wearing comfort, the myopia prevention glasses based on the artificial intelligence algorithm are invented, and eye health of a user can be protected to the greatest extent.

The invention uses sensors with multiple functions, such as a wearing state sensor, an azimuth and acceleration sensor, a light sensor, a distance sensor and the like, comprehensively senses the environmental state and the eye using state of a user, and carries out customized setting according to historical data used by the user.

The intelligent glasses for monitoring the eye state and actively protecting the myopia are composed of the following parts: one or more infrared light distance sensors, one or more human eye light sensors, an angle sensor, an acceleration sensor, a wearing state sensor, a battery, a single chip microcomputer, a reminding atmosphere lamp and optical components thereof, glasses with atomizing functional lenses or films and other necessary electronic circuits and mechanical structures.

The intelligent glasses for eye state monitoring and active myopia protection work by the following principle.

The method comprises the steps that one or more infrared distance sensors and one or more angle sensors are utilized to indirectly or directly detect the effective distance between the glasses or eyes of a glasses wearer and an observer, and once the effective distance is judged to be smaller than the safe eye using distance, the atomization functional lens or the atomization functional film is controlled to periodically change in an atomization state and a transparent state according to a preset rule, so that the glasses wearer is reminded and forced to adjust the eye using distance until the healthy eye using distance is reached.

The detection of the environment of the surrounding environment is realized by one or more human eye light sensors, and once the glasses wearer is judged to be in the unsafe eye environment, for example, the surrounding light is too dark or the screen is watched for a long time, the atomization functional lens or the film is controlled to periodically change in the atomization state and the transparent state according to a preset rule, so that the glasses wearer is reminded and forced to adjust the eye environment.

Through the comprehensive analysis to multiple sensor data, whether intelligent recognition user sits for a long time or uses eyes for a long time to do corresponding health suggestion.

The state of the glasses wearer is judged by utilizing the angular velocity sensor, the acceleration sensor and the magnetic field sensor and through artificial intelligence. Only when the glasses are in wearing and reading states, the corresponding devices and the reminding function can be started. And at other times, the corresponding device enters a standby power-saving mode.

In consideration of safety, the atomization functional lens or film is a lens or film which is in a transparent state after power failure, and is periodically switched between the atomization state and the transparent state when activated, so that the function of reminding and forcing a glasses wearer to adjust the eye using state is realized, and the situation that the safety of a user is harmed due to the fact that the visual field is blocked even under the condition that the battery of equipment is exhausted is ensured.

The atmosphere light reminding function is invented, and the grading reminding function is realized together with the lens atomization reminding function. The eye use state monitoring data and the comprehensive analysis data are recorded, the Bluetooth function and intelligent equipment such as a mobile phone with APP are used for communication, data are uploaded, scientific eye use suggestions are provided, and parents can conveniently supervise the eye use state in one day or a period of time; the user can also customize key parameters and threshold values of the glasses through the intelligent equipment so as to adapt to use scenes of different users; the latest firmware and software can be downloaded from the Internet through the intelligent equipment to upgrade the glasses.

A large amount of user data is gathered to a cloud server; and optimizing an intelligent algorithm through analysis of big data.
