摘要
针对盲人行动不便和行动范围受限的问题,设计一种基于ZigBee的盲人室内定位导航及远程监控系统。利用超声波技术、热释电红外技术和语音合成技术,设计出便携装置;通过研究质心定位算法,设计出RBIWCL算法;利用GSM/GPRS技术,设计出与智能终端进行远程通信的方法。结果表明,便携装置能有效检测障碍物并及时提醒盲人,RBIWCL算法提高了定位精度,远程智能终端能实时准确地监控盲人的位置和行动轨迹。
For the problem of walking inconvenience and limited walking range,a blind indoor location,navigation and remote monitoring system is designed based on ZigBee.A portable device is designed by ultrasonic technology,passive infrared technology and text to speech technology.Range-based improved weighted centroid localization（RBIWCL）algorithm is designed by studying the centroid localization algorithm.The method of communicating with the remote intelligent terminal is designed by GSM/GPRS technology.The results show that the portable device can detect an obstacle effectively and remind the blind timely.RBIWCL algorithm improves the locating accuracy.The remote intelligent terminal can accurately monitor the position and action track of the blind in real time.
