基于Python的智能控制轮椅的研究与设计

Research and Design of Intelligent Control Wheelchair Based on Python

针对普通电动轮椅功能单一的问题,利用Python控制及多传感器实现了对电动轮椅的智能控制。Python开发板控制驱动电机、传动机构,实现轮椅的行走和座椅的升降。倾角传感器、速度传感器、加速度传感器、超声波传感器实时测量和监控行走速度、加速度、座椅倾斜角度、障碍物情况,从而使系统自动判断和控制轮椅速度和刹车。特别是下坡时,当速度超过设定极限值,就自动进行刹车减速到适宜的速度。多功能轮椅具有太阳能辅助供电、手动剪叉式座椅升降、腿部加热、语音提示、刹车等多功能模块,提高了轮椅的舒适性、安全性和多用性。

Ordinary electric wheelchair has a single function. This uses Python control and multiple sensors to realize intelligent control of electric wheelchair. The Python development board controls the drive motor and transmission mechanism to realize wheelchair walking and chair lifting. Tilt sensor, speed sensor, acceleration sensor, ultrasonic sensor real-time measure and monitor walking speed, acceleration, seat tilt Angle, obstacles, so that the system automatically judge and control wheelchair speed and brake. Especially downhill, when the speed exceeds the set limit, it will automatically brake and slow down to the appropriate speed. The multi-function wheelchair is equipped with solar energy auxiliary power supply, manual fork chair lifting, leg heating, voice hint, brake and other multi-function modules, which improves the comfort, safety and versatility of the wheelchair.
