基于DSP+单片机的主从式电动轮椅控制器设计

A Design of an Electric Powered Wheelchair Controller with the Principal and Subordinate Structure Based on DSP and MCU

给出了一种新型的基于DSP+单片机的主从式电动轮椅控制器的设计方案。系统的操作与显示模块由单片机(C8051F020)、液晶显示、操纵杆及按键组成,系统的驱动模块由DSP(TMS320LF2407A)、直流永磁电动机及驱动电路组成,主从机之间采用串口通信方式实现数据的传输。实验结果表明该主从系统能够实现轮椅的多种运动,控制效果较好。

A new type design of an electric powered wheelchair controller of the principal and subordinate structure based on DSP and MCU is presented. MCU, LCD （liquid crystal display） ,joy stick and keypad are included in the operating and display modules of the system. DSP （TMS320LF2407A） ,direct current permanent magnet motor and driving circuit are included in the driver module of the system. The communication between the principal and subordinate is serial communication. The experiment result shows that the principal and subordinate mode system can realize wheelchair＇s various kinds of movements and the controlling effect is good.
