基于MSP430的无线环境监测系统设计

Design of Wireless Environmental Monitoring System Based on MSP430

无线环境监测系统由一个监控终端和多个探测节点组成。监控终端由无线收发模块、探测模块、液晶显示及键盘模块组成，通过无线模块收集其它探测节点的环境数据，并能显示和查询各节点的环境数据，同时实现本地环境数据的探测，对超过监测阀值的节点（包括本地和远端节点）数据提供告警功能。探测节点也由无线收发模块和环境监测模块组成，可实现对周边环境数据的探测，同时能上报环境数据。为拓展环境监测系统的覆盖范围，这里采用了预设路由的接力数据传输方式，有效解决了低功耗无线传输模块传输距离近的问题。

Wireless Environmental Monitoring System comprises a monitoring terminal and several detectation nodes. Monitoring terminal comprises a wireless transceiver/receiver module, a detection module, an LCD and a keyboard module. The environment data of other nodes are collected by the wireless module. It can display and inquire the environment data of each node; at the same time, it can detect the local environment data and provides the warning function when the nodedata exceed the monitoring threshold value. Detection nodes, also comprising a wireless transceiver/receiver module and a environmental monitoring module, can detect and upload surrounding environment data. In order to expand the coverage area of Wireless Environmental Monitoring System, we adopted the relay transmission mode of default rotlte, which solved the problem of the short transmitting distance of the low power wireless transmission module effectively.
