DETAILED DESCRIPTION
[0009] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figure 1-8 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.
[0010] The intelligent myopia prevention glasses adopted in this embodiment include a glasses frame 2, a glasses frame 1 for connecting the glasses frame 2, and a first glasses leg 8 and a second glasses leg connected to both sides of the glasses frame 2. The inner wall of the first glasses leg 8 is provided with a circuit board groove 6 and a myopia warning light 4, and the control circuit board 5 is installed in the circuit board groove 7 and the circuit board groove 7 is closed by a circuit board groove baffle; an invisible light transmitting and receiving head 3 is installed on the glasses frame 2, and a battery groove 11 for installing a rechargeable battery 10 is provided on the inner side wall of the second glasses leg, and the battery groove 11 is closed by a battery baffle 9. A charging port 12 is also provided at the end of the second glasses leg.
[0011] The control circuit board 5 of this embodiment includes a tilt control module, a distance measurement module, a clock interface module and a control module, wherein the distance measurement module uses TOF technology to emit invisible light and receive return light, and uses the time difference between the two to calculate the measured distance.
[0012] The tilt control module is mainly composed of a tilt sensor, which is used to measure the tilt of the glasses. When the user wears glasses for preventing myopia, the tilt control module for preventing myopia starts to work. By measuring the tilt of the glasses, a signal is generated to indicate whether a specific tilt has been reached and transmitted to the controller. If the horizontal tilt of the glasses is less than the specified value, it means that the user is not reading or writing, and the distance measurement module does not work, thereby saving energy. If the horizontal tilt of the glasses is greater than the specified value, it means that the user is reading or writing, and the distance measurement module starts to work.
[0013] The clock interface module obtains the time between emitting invisible light and receiving the returned light, and passes the data to the distance measurement module. The control module uses the CH579F chip, and its main function is to determine the distance between the user's eyes and the object being viewed. It receives the measured distance from the distance measurement module through the SDA data interface and compares it with the set clear vision distance. The judgment formula is as follows: l〉L Among them, l is the distance tested by the clear vision distance measurement module, and L is the clear vision distance. There are three gears, gear 1 is 33CM, gear 2 is 35CM, and gear 3 is 37CM. If the measured distance exceeds the clear vision distance, a signal will be sent through the serial communication terminal to the myopia warning light 4 of the reminder LED, controlling the LED light to flash twice to remind the user that the distance is too close. The flashing LED light reminds the user that there is an incorrect reading or writing posture, thereby preventing myopia and correcting pseudomyopia.
[0014] When the distance measurement task is completed, the controller will control the clear visual distance measurement module to rest for 10 seconds before starting the second distance measurement to achieve power saving.
[0015] The power supply module of this embodiment is composed of a rechargeable lithium battery, a charging and power consumption software management system, and a magnetic charging interface 12. The module is powered by a lithium battery and can be charged and used repeatedly, which is convenient and fast. The power consumption software management system can analyze the battery power. When the remaining power is insufficient, the low power signal light will light up to remind the user to charge in time. When the battery is fully charged, the charger power reminder signal light will light up to remind the user that the battery is fully charged. The charging interface adopts a magnetic charging interface, which is convenient and fast, not easy to damage, and has a data transmission function to save the interface, which is conducive to reducing the size of the device and reducing the weight of the device.
[0016] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
