摘要
为了保证灾难现场搜救人员的自身安全,提出一种基于单片机和ZigBee技术的搜救人员特征信息无线传输新技术。着重了介绍了无线传输单元的设计原理、硬件组成以及实现方法。同时,提出了改善ZigBee传输距离的方法,使得传输距离大于100 m,速率达到50 kbit/s,可以较好地满足现场应用要求。
To guarantee the safety of search and rescue persons in disarster site, a new wireless transmission technology is presented based on SCM and ZigBee for transmitting the characteristics information about the search and rescue persons. The design principle, hardware composition and implementation of the wireless transmission unit are emphasized. At the same time, a method for improving the ZigBee transmission distance is provided. More than 100 metres transmission distance is achieved and the transmission rate is 50 kbit/s. The unit completely meets the site application requirements.
