摘要
视力下降给很多人的日常生活带来了极大的影响,对此,设计一款便携式的视力自助检测仪,对缓解视疲劳情况和改善用眼健康有着重要的作用.设计采用电子、信息识别、液晶显示屏(liquid crystal display,LCD)显示、红外遥控、SD卡存储等技术相互结合,利用Keil MDK5软件通过C语言编程实现各模块控制连接.用户控制红外遥控器对图标"E"的方向进行判别,满足4.0~5.2的视力测试需要,同时视力检测仪还附有色盲检测功能.本装置的设计大小为22 cm×13 cm×6 cm,实现用户独立检测视力的功能,检测仪具有实用性、实时性和便携性,有更快的处理速度、更准确的检测结果.此装置的设计可以更好地为用户带来便捷,有很好的发展前景.
Vision decline has brought a great impact on many people’s daily life.To this end,the design of a portable vision self-detector has an important role in relieving visual fatigue and improving eye health.The design uses the combination of electronics,information recognition,liquid crystal display(LCD)displaying,infrared remote control,SD card storage and other technologies,and uses Keil MDK5 software to realize the control connection of each module through C language programming.The user controls the infrared remote control to distinguish the direction of the icon“E”,which meets the needs of visual acuity test from 4.0 to 5.2.Meanwhile,the visual acuity detector is also equipped with color blindness detection function.The design size of this device is 22 cm×13 cm×6 cm,which can realize the function of user’s independent vision detection.The detector is practical,real-time and portable,with faster processing speed and more accurate detection results.The design of this device can better bring convenience to users and has a good development prospect.
