摘要
以适用于环境监测的无线传感器网络系统为对象,设计并开发了相应的节点硬件。将μC/OS-Ⅱ实时操作系统移植于汇聚节点的处理器上,并结合无线传感器网络汇聚节点的特性,设计了合理的多任务调度机制。传感节点设计了实时采集和按需采集两种工作方式。开发了串口通信程序,实现了传感器节点数据的实时监控。测试结果表明,该系统运行良好。
The node hardware of wireless sensor network system is designed and implemented tor environmental monitoring. The μC/OS-Ⅱ embedded real time operation system is transplanted successfully on sink node processor. Combined with the features of the WSN sink node, a multi-task scheduling mechanism is designed. Two different models of real-time data acquisition and on- demand data acquisition are designed. The serial communication program is developed and the real-time monitoring of the WSN settsor nodes is implemented. Test result shows that this system performs well.
