智能导盲杖的设计研究
Design and Study of Intelligent Guide Rod

针对视障人士无法识别道路状况这一根本问题，本团队拟研制一款智能导盲杖。以HT66F2390单片机为主控制芯片。导盲杖的杖身可以伸缩调节，适应各个高度人群使用。在触感GPS导航工作同时，通过摄像头模块识别红绿灯以及障碍物。在此基础上加入GSM模块、NRF模块、陀螺仪等传感器。进而实现语音触感导航，障碍物提醒，熟人识别，实测心率，摔倒报警，危险报警呼叫，无线寻杖，夜间亮警示灯等功能。在一定程度上解决了视障人士出行的安全问题。
In response to the fundamental problem that the visually impaired people cannot identify the road conditions, the team plans to develop an intelligent guide rod. The HT66F2390 microchip is the main control chip. The body of the guide rod can be adjusted and adapted to the use of various high groups. While the tactile GPS navigation works, identify the traffic lights and obstacles through the camera module. On this basis, GSM module, NRF module, gyroscope and other sen-sors are added. Then realize voice tactile navigation, obstacle reminder, acquaintance recogni-tion, measured heart rate, fall alarm, dangerous alarm call, wireless rod search, light warning light at night and other functions. To some extent, it solves the safety problem of visually impaired people.
