基于ZigBee无线传感网的泥石流多发地数据采集系统

针对有线传感网数据采集系统布线成本高以及无法在环境恶劣的野外放置等问题,介绍一种基于ZigBee无线传感网的数据采集系统。该系统由基于MSP430单片机的主机、子机组成,子机由太阳能供电连接传感器,放置在户外采集数据,主机连接PC机放置在室内,主机和子机通过ZigBee无线网络通信。该系统实现了野外数据的采集和无线传输,具有实时性、稳定性等特点,可用于地质分析和泥石流预警等系统,以及各种无线传感网数据采集系统。

Data acquiring system based on ZigBee wireless sensor network used in mudslide place

Due to the high cabling cost of data acquisition system and its infeasibility in poorenvironment for wiring sensor networks,this paper presented a design of wireless data acquisition system which is based on the ZigBee protocol-based wireless sensor network. The system is composed of sub machine and host machine which are implemented by the MSP430 SCM and the PC. The sub machine powered by solar energy connects sensors. It is placed outdoors to gather the data. The host machine is placed in the room to connect the PC. Host machine communicates with sub machines through the ZigBee wireless network. This system realizes data acquisition and wireless transmission,guarantees the real-time transmission and stability. It can be implemented in the fields where mudslides frequently happen. It is suitable for geological analysis and mudslides warning or other wireless sensor data colleting system.
