Embodiment Construction

[0012] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, an intelligent myopia preventer includes: 1 ultrasonic sensor, 2 silicon photocells, 3 keyboards, 4 controllers, 5 voice chips and 6 speakers. The ultrasonic sensor, the silicon photocell, and the keyboard are connected to the controller, and the controller is connected to the speaker through the voice chip. This program uses an ultrasonic sensor to measure the eye distance, uses a photocell to measure the brightness and darkness of the light, and uses a single-chip internal timer to calculate the eye time, and is equipped with 4 time period selection switches to meet the needs of people of different ages; Finally, the voice chip is used to realize the voice alarm prompt. The system has the characteristics of convenient use, high degree of intelligence, and friendly man-machine interface.

Abstract

The invention discloses an intelligent myopia preventer, which comprises: an ultrasonic sensor, a silicon photocell, a keyboard, a controller, a voice chip and a loudspeaker. The ultrasonic sensor, the silicon photocell, and the keyboard are connected to the controller, and the controller is connected to the speaker through the voice chip. This program uses an ultrasonic sensor to measure the eye distance, uses a photocell to measure the brightness and darkness of the light, and uses a single-chip internal timer to calculate the eye time, and is equipped with 4 time period selection switches to meet the needs of people of different ages; Finally, the voice chip is used to realize the voice alarm prompt. The system has the characteristics of convenient use, high degree of intelligence, and friendly man-machine interface.

Description

technical field [0001] The invention relates to the technical fields of sensing detection and single-chip microcomputer control technology, and in particular to an intelligent myopia preventer. Background technique [0002] According to the survey, the incidence rate of myopia in the world is 22%, and the incidence rate in Asia is as high as 31%. The prevalence rate of myopia is high among school-age children and adolescents. In my country, the myopia rate of primary and middle school students has reached 34.6%, and the myopia rate of high school students has reached 70%. It can be seen that how to prevent juvenile myopia is urgent. [0003] At present, there are two main methods for preventing myopia: one is a mechanical posture correction device; the other is a myopia prevention alarm based on a wearable electronic distance measurement. Method 1 is very inconvenient to use; Method 2 does not take into account the factors that will lead to vision loss due to prolonged eye...
