Gao Jing-mi · Microcomputer Information · 2010
In this paper,it was introduced that using a multi-sensor system for avoiding obstacle for intelligent wheelchair by using multiple ultrasonic sensors and infrared sensors to solve the environment information couldn't be precision and detail achieve by single sensor.It applied LPC2210 as its controller,comprising five transmitting receipting sensors,four pairs of infrared sensors,a temperature sensor DS18B20 and all of above constructed the multi-sensor perception system.It also introduced the whole hardware design system and further offered the experimental results analysis.Therefore it can make use of this obstacle avoidance detect system to control the intelligent wheelchair,with the characteristics of good timing,high accuracy and high robustness.
