基于超声和红外传感器的探测系统设计

Design of detection system Based on ultrasonic sensors and infrared sensors

为了克服单一传感器固有的缺陷,本文研究了超声波传感器和红外传感器构成的智能轮椅避障感知系统。它采用了以ARM7TDMI-S为内核的单片机LPC2210作为控制器,包括收发一体的超声波传感器、红外传感器和DS18B20温度传感器等组成的多传感器感知系统。介绍了整个硬件设计并对实验结果进行了分析。可利用此避障探测系统对智能轮椅进行实时性好、精确度高和鲁棒性强的避障控制。

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.
