自助式视力检测仪器的设计

The design of self-service vision detecting instrument

本团队致力于研制一套自助式视力测试仪器,以实现使用者独自在该智能仪器的辅助下可以对自身的视力状况进行检测。本设计采用STM32F103RCT6型单片机作为控制单元的核心芯片,结合屏幕显示图标输出以及按键输入进行仪器硬件整体的搭建,软件采用C语言编程设计,实现了便捷进行视力检测的效果,包括远近视视力度数检测、色盲检测、散光检测等,同时拥有眼保健操、视力小游戏、视力小知识等功能板块。实验测试与调查结果表明,该仪器体积小,使用方便、检测结果准确、运行可靠;与传统的检测视力方式相比,该仪器的使用能够有效地避免人为机械记忆视力表的现象发生,同时节省了部分眼科医护人力资源。

This team is committed to developing a self-service vision test instrument, in order to realize the user alone in the help of the intelligent instrument to test the own eyesight condition.This design adopts STM32F103RCT6 type single-chip microcomputer as core chip of the control unit, combined with the screen display icon on the output and the overall key input constructing instrument hardware, software using C language programming design, which has realized the convenient detection of vision effect, including distance vision degree detection, color blind detection, astigmatism and so on, also has the eye exercises, visual function such as little game, visual knowledge plate.The experimental test and the results of the survey show that the instrument is small in size, easy to use, test results are accurate and reliable operation;Compared with the traditional way of detection of vision, the use of the instrument can effectively avoid the phenomenon of artificial mechanical memory end, save a part of the eye health human resources.
