摘要
为了满足人们日益发展的视力检测需求,使用SPCE3200微控制芯片,外部扩展TFT-LCD模块和键盘输入模块,设计出一种基于测试人员自主检测的视力检测系统。该系统的设计旨在为视力的自主检测提供方便可靠的帮助。经实际测试结果表明,该系统简单高效特点鲜明,测试者个人即可独立完成视力检测的全部步骤,避免了舞弊和人为失误的情况发生。
In order to meet the increasingly developing people＇s demand of vision detection,a testing eyesight system based on self-test is designed,combined with embedded design method,using the SPCE3200 micro-control chip,expanding tft-lcd module and keyboard input module.The design of this vision system is order to provide convenient and reliable independent testing of the help.This actual test results shows that the system is simple efficient distinct characteristics,the tester can finish the test process individual independently,avoiding the fraud and human error.
