摘　　要：为满足大型复杂建筑物室内精确定位导航、无缝监控预警、应急事件管理等方面的应用,设计了一种便携的基于S3C6410和无线传感器网络的手持数据采集终端。给出了手持终端系统的总体原理框图,S3C6410处理器和Zig-Bee无线传输模块通信的串口接口方式。提供了无线传输模块的硬件电路原理图和手持终端的硬件组成框图,并提供了模块采集程序和串口通信程序。试验结果表明,手持终端实现在室内完成数据采集和无线传输,室内定位精度优于3 m(95%),系统初次定位时间少于30 s,系统可用性优于90%。To meet the applications of precise indoor positioning and navigation, seamless monitoring and warning, emergency incident management and so on in the large-scale and complex building, this paper designed a portable handheld datacollection terminal based on S3C6410 and wireless sensor network （WSN）. The system overall block diagram of handheld terminal and serial communication interface between S3C6410 processor and ZigBee wireless transmission module were given. Then the paper provided the hardware circuit schematic of wireless transmission module and the hardware block diagram of handheld terminal, and also provided the program of module data-collection and serial communication Experimental results show that the handheld terminal has finished indoor data-collection and wireless transmission, indoor accuracy of location is better than 3m （95%）, the time of initial positioning is less than 30s, and system availability is better than 90%.
