突发性环境污染事故的应急监测要求监测数据能及时而有效地采集和传输,以便管理部门能够及时应对各种突发状况。针对传统的有线传输网络铺设麻烦、可移动性差和数据传输不稳定等问题,设计了一种应用于污染源应急监测系统的无线传感器网络节点,硬件上采用C8051F340微控制器和XBee-PRO无线传输模块构架节点,并构建了一个基于ZigBee技术的无线传感器网络,最终实现污染源现场数据的高效采集、传输以及处理。研究结果表明,该无线传感器网络节点能应对各种突发情况,具有很好的稳定性。

Design of wireless sensor network node for emergency environmental monitoring

Emergency monitoring for sudden environmental pollution accident requires that the monitoring data can be collected and transmitted timely and effectively in order that management can respond promptly to all kinds of unexpected dilemmas.Aiming at dealing with the drawback of the traditional wired transmission networks inconvenient pave,weak mobility,unsafe and unstable data transmission,a wireless sensor network node applied to pollution emergency monitoring system was designed.The system structured nodes with C8051F340 microcontroller and XBee-PRO wireless transmission module on the part of the hardware and built the wireless sensor networks based on ZigBee.The pollution sources on-site data collection,transmission and processing were realized.The results indicate that the nodes are stability enough to cope with various emergency situations.
