摘　　要：从助老助残的需要出发,以降低成本和操控灵活为目标,采用AT89S51单片机研制了一款电动轮椅控制器。首先介绍了控制器的组成功能模块,然后详细分析了其控制及驱动电路的原理,包括H桥驱动电路构成及分类,功率MOSFET导通过程,关键元器件的参数选择。与硬件相结合,对方向控制的实现进行了算法设计并编程实现。实验结果表明该控制器满足较大功率直流电机的驱动需要,且操作轻便,控制灵活,满足老弱及下肢患者的操作需要。In order to reduce cost and improve the operation flexibility of the old and lower limb disabilities, we develop an electric wheelchair controller by using single-chip computer AT89S51. The paper introduces the composition and the function dodules,analyzes the principle of the control circuit that includes the classification of the H-bridge drivering circuit,the work process of power N-MOSFET, the parameter selection of the key components. Combined with the hardware,the directional control algorithm and the programs are designed. The experimental results show that the controller is easy to operation, flexible to control, suitable for driving higher-power DC motor and meets the operational needs of the old and lower limb disabilities.
