B43 - 基于STM32单片机的自动视力检测仪
任务
本系统设计了一个基于STM32单片机的自动视力检测系统，通过单片机控制LCD高清液晶显示屏显示“E”字形的开口方向和大小，来替代传统的视力测试面板；通过语音播放模块进行测试过程的提示语播放、语音识别模块进行识别测试者对于当前屏幕显示“E”形状的开口方向的回答，完成对测试者的自动视力检测过程；通过无线按钮为听力受损人员提供手动按下方向按键回答屏幕显示“E”行方向和大小的功能。本系统整体设计功能和参数如下。
设计功能:
（1）采用LCD高清液晶显示“E”字形，涵盖视力检测板所有“E”形状和大小。（2）自动化语音提示，确保检测者知道当前需要做什么。
（3）智能化语音识别，系统精准采集测试者的回答结果。
（4）无线按键，方便用户通过选择按下的方向按键回答显示屏“E”开口方向，扩大适用人群和使用环境。
（5）采用QT设计安卓程序，通过蓝牙和主控板连接，能够记录和显示测试者本人的近期视力检测结果，可以通过蓝牙应用程序或者在液晶屏上获取到对应的折线图，使用户方便直观的看到视力检测结果的变化。
（6）检测系统在调取检测结果时，可以根据历史检测结果做出温馨提醒，比如“近期视力检测下降，请注意适当休息哦！”。
设计参数：
（1）显示屏幕细腻，分辨率最低480*320，屏幕尺寸采用3.5寸。
（2）无线通讯距离不低于5米。
（3）语音识别：非特定人识别，2米内识别准确率95%以上，识别速度2秒以内。
（4）识别语种：中文。
（5）语音播放功率不小于3W。
（6）检测结果可存储不低于100人，可记录每人最低20条最近测试结果。

语音识别模块
LU-ASR01鹿小班智能语音识别模块是由鹿小班开源电子厂家设计生产的一款高性能语音识别模组。该模块支持天问公司的block软件，是天问ASR主板系列之一，支持以可视化代码积木的方式配置语音指令、设定语音识别提示、串口输出指令信息等。模块扩展了8个输出I/O口用于直接和控制设备相连，且支持DHT11温湿度模块直接采集的特性。该模块支持10米超远距离唤醒功能、超过98%的超高识别准确率。本系统将LU-ASR01语音模块的输出串口TXD连接到了从机的串口3对应的PB11引脚用于接收语音识别后的输出指令。通过LU-ASR01语音识别模块的开发平台设定好语音识别指令词和识别到关键词的串口输出内容，当语音模块接收到测试者的语音并处理解析到对应的指令词后，通过串口向从机输出设定的指令对应数据用于系统的逻辑处理。

在此占位，后期有时间整理了再开源。
