无线传感器网络在环境应急车中的设计与应用

Design and applications of wireless sensor network in environmental emergency vehicle

针对传统的环境应急车获取现场数据耗时、复杂、不够灵活的缺点,提出了利用Z igBee无线传感器网络对污染现场进行数据采集和实时监测的方案。该方案将传感器终端布置于污染现场进行监测,并将监测的数据通过Z igBee无线通信协议传输给路由器、协调器,最终把数据提交给上位机软件进行分析整理并导入数据库。硬件上采用C8051F340微控制器与XBee-PRO无线模块相结合设计各节点。本设计功耗低、体积小、成本低,使用方便,适用于环境应急车对污染现场的监测。

The methods of traditional environmental emergency vehicles collecting field data were time-consuming, complex and inflexible. This paper presented a program of pollution field data collection and real-time monitoring using ZigBee wireless sensor network. Set the sensor terminal to the pollution region and detected, transmitted the field data to router and coordinator by the ZigBee wireless communication protocol. Finally, processed environmental monitoring data and imported to database by software. Designed each node in hardware with C8051 F340 microcontroller and XBee-PRO RF module. The design of low power, small size, low cost and convenient, is suitable for environmental emergency vehicles to monitor on-site data.
