摘要
基于功能强大的工控元件可编程序控制器(PLC)开发的盲人行走引导系统——导盲小车,由不同部位的传感器所探测到的障碍信号,通过编程,经由PLC处理后,输出语音信号,指导使用者在小车的引导下准确越过障碍.
Based on Programmable Logical Controller （PLC）, a leading system for blind person-blindguided-handcart is designed. Regarding to detected signals which are measured by different sensors on the handcar and converted into different sound information by program, the user can be able to operate this device to walk correctly.
