Design And Research Of Synoptophore Control System Based On ARM

Amblyopia is not uncommon.Foreign reports indicate that in the general population,the incidence of amblyopia is 2 to 2.5%,and the incidence of amblyopia in China is about2 to 4%.Amblyopia is a common and frequently occurring disease.Amblyopia is also the most common disease in childhood.The incidence of the disease is high,accounting for 2to 3% of the total proportion of children.Since childhood is a critical period of visual development,these eye diseases during childhood are very detrimental to the development of children's eyesight.Many eye diseases,if not cured during childhood,will result in life-long disability of the eyes.Synoptophores is now recognized as the best eye treatment device for the treatment of amblyopia.This article uses an ARM-based control chip to use Haidinger brush-guided localized amblyopia treatment.The method is firstly to accurately guide and find the macular fovea through the Haidinger brush,and then according to the eccentric gaze amount,select a suitable picture with black dots to treat amblyopia patients,which greatly increases the therapeutic effect on amblyopia.Compared with the traditional synoptophores,all the controls of the improved synoptophores can be operated on the LCD screen.First,the treatment method can be selected on the LCD screen,and after the selection,the interface of the treatment method will be displayed through the control interface.The button to change the treatment method of time,light intensity,motor speed and other treatment parameters.The improved synoptophore machine replaced the traditional synoptophore light source and the picture cassette with the LCD screen.The liquid crystal screen not only serves as a light source but also can simultaneously display the pictures required for treatment.The treatment of more pictures,ARM can not be stored in large quantities,so the U disk to store treatment picture.The improved synergy is more effective than conventional synergy in terms of the treatment effect,and the operation is more human and intelligent.The hardware design and software program design of the ARM control system in this article are based on the STM32F429 chip.Use the STM32F429 development board to debug the algorithm that has been determined.The Keil programming software is used for the program design.The new type of synoptophores developed in this paper have shown good treatmenteffects and data on the treatment of amblyopia patients.The treatment efficiency is relatively high.
