基于ZigBee和GPRS的船载货物状态远程监控系统设计

System of Remote Monitoring System for the State of Ship's Cargo Basing on ZigBee and GPRS

通过研究GPRS和ZigBee协议及WSN技术,提出了一种基于GPRS和ZigBee的船载货物状态远程监控系统.系统借助ZigBee技术在短距离、低功耗无线通信和GPRS网络远程数据传输的优势,采用簇树网络拓扑结构,对船载货物状态进行实时监控,并将采集到的货物状态数据以及货物周围的环境数据发送到监控中心,监控中心对这些数据进行实时统计.当货物产生异常情况时,货物状态数据可以为监控中心的管理人员提供决策依据并实施相应的措施.同时系统具有功耗低、成本低、实时性高和布线方便等优良特点.

Based on the study of GPRS,ZigBee protocol and WSN technology,a new design of the state of ship＇s cargo remote monitoring system is put forward.By means of ZigBee protocol advantages in short-distance wireless communication and GPRS network in long-distance data transmission.And uses the cluster-tree network topology on the condition of the cargos on the ships for real-time monitoring.Sending the collected data on cargos and the cargos surrounding environmental data to the monitoring center,monitoring center monitors these data for real-time.When the cargos anomalies arise,the cargos status data can provide basis for the decision making to the management of monitoring center and do some implementations of appropriate measures.This system has characteristic of low power dissipation,low cost,high real-time and easy wiring,etc.
