轮椅左右腿同步运动系统设计

Design of synchronous motion system for left and right legs of wheelchairs

为了解决轮椅在爬楼过程中左右腿不能同时着地受力,造成轮椅偏斜的问题,设计了一种基于PC与STC12LE系列单片机的轮椅左右腿同步运动系统.在系统硬件设计部分,介绍了该系统的硬件组成、连接关系和工作原理;在系统软件设计部分,主要介绍了单片机程序流程图和单输入模糊控制在同步运动控制过程中的应用.该系统在最近测试过中,实验结果符合设计要求,且表现出操作简单、反应灵敏、性能稳定等优点.

In order to solve the problem that the left and right legs of the wheelchair can not touch the ground at the same time and have even forces in the process of climbing the floor, and then cause wheelchair deflection, a synchronous motion system is designed based on PC and STC12LE series mcu. In the part of system hardware design, the hardware composition, connection and working principles are introduced; in the part of system software design, the application of MCU program flow chart and single input fuzzy control in synchronous motion control process are mainly introduced.The recent test results show that the system meet the design requirements and show advantages of simple operation, sensitive response, stable performance and so on.
