Myopia preventing system based on automatic detection technology

Abstract

The invention relates to a myopia preventing system based on an automatic detection technology. The myopia preventing system comprises a studying table, an LED table lamp, a photosensitive resistance sensor, an ultrasonic distance sensor, an infrared sensor, a controller, a power supply and a PCB circuit, wherein the photosensitive resistance sensor, the ultrasonic distance sensor and the infrared sensor are all electrically connected with the controller through the PCB circuit. Through the feedback information from the photosensitive resistance sensor, the ultrasonic distance sensor and the infrared sensor, the luminance of the LED table lamp can be adjusted; whether a user is in the studying table or not, and determination of the posture of the user are performed, so that it is ensured that light intensity received by the eyeballs of the user is constantly in a comfortable range; and in addition, the myopia preventing system has functions of timing and sitting posture reminding, so that vision of the user can be more effectively protected.

Description

technical field [0001] The invention relates to the technology belonging to the professional field of automatic detection and electric power technology, in particular to an anti-myopia system based on the automatic detection technology. Background technique [0002] There is an existing anti-myopia system that measures the distance of objects seen by the human eye through an ultrasonic sensor placed in front of the human eye, and sorts out and sends the information to the mobile phone at all times. The information that calculates the long-term vision time is transmitted to the user through an alarm. Ultrasonic sensor, processor, Bluetooth transmitter module, switch, drive circuit, buzzer, battery, glasses clip, glasses, Bluetooth receiver module, host computer software, and mobile phone. It solves the problem that people cannot always know their own eye use conditions in daily life, which leads to damage to the user's eyes. [0003] First of all, it is obvious that the comp...

Solve the problem that people cannot always know their own eye use in daily life, which leads to damage to the user's eyes

[0003] First of all, it is obvious that the composition of the existing system is relatively complicated. Taking the Bluetooth function as an example, users are required to have a mobile phone, while the anti-myopia system is mostly used for groups that often use their eyes, such as elementary and middle school students, but elementary and middle school students rarely own mobile phones. Once you have a mobile phone, there is no way to calculate the long-term viewing time with the mobile phone

Secondly, the system hardware is placed in front of the user's eyes with a device similar to glasses, which will cause interference to users without visual impairment and is not practical enough

Secondly, due to the limited volume of the spectacle frame itself, the power supply capacity of the system is also limited, and it needs to be charged continuously
