中文摘要：
针对气体在开放式空间扩散的问题,手机了基于无线传感网的气体扩散立体监测系统。监测系统由多个无线传感器节点和基站组成。低功耗设计的无线传感器节点具有无线通信、串行通信、GPS自定位、计算控制等功能,传感器节点之间通过MESH网络实现多跳组网通信。实时操作系统上运行的网络协议可提高系统运行的实时性和可靠性。系统上位机软件能够显示气体在三维空间中的扩散情况,并显示天气状况和节点的剩余电量信息。通过外场测试表明,该系统能够实时监测含磷气体扩散情况,为防止进一步造成较大的损失提供可靠的信息。
英文摘要：
A tridimensional wireless sensor network system for monitoring phosphorous gas diffusion is proposed. Lower-power design and miniature nodes have functions of wireless communication, serial communication, GPS self-localization, computing and control. Nodes communicate through MESH multi-hop network. The network protocol is built on the real-time operating system to improve the reabtiming and reliability of system. The monitoring software, which run in PC operation system, can real-time display the spread situation of poisonous gas in the 3-D space, the weather conditions and the remaining power of nodes. The field test shows that this monitoring system can monitor the spread of phosphorous gas and provide reliable information to avoid greater loss.
