摘要:

为解决传统监测系统中布线麻烦、覆盖面积窄、节点不易移动等问题,设计了一种基于ZigBee和3G无线网络的远程监测系统；整个系统由ZigBee无线传感网、3G-ZigBee网关节点、3G网和监控中心组成；ZigBee节点由射频模块、主板、传感器模块和电源模块组成,射频模块由CC2530与CC2591加长距离式组合组成,3G-ZigBee网关以ARM9微处理器S3C2440和Linux操作系统为核心进行开发,实现了ZigBee网和3G网之间的连接；该系统应用于水族馆鱼缸中的水质监测系统,对温度、PH值、电导率、溶氧量、氨氮等参数进行测量；结果表明该系统实现了数据的稳定采集和较高的数据传输速度,满足了现代监测系统的要求。

Abstract:

To solve the problems in traditional monitoring system including wiring problems, covering narrow, node’s immobility and so on. A remote wireless monitoring system based on ZigBee/3G is designed. The whole system is composed of ZigBee wireless sensor network, 3G-ZigBee gateway’s node, 3G network and monitor’s center. The nodes in wireless sensor networks are composed of RF module, the mainboard, sensor module and power supply module. The RF module is composed of the length distance combination CC2530 and CC2591. The connection between ZigBee network and 3G is implemented by 3G-ZigBee gateway’s node which is developed with the microprocessor S3C2440 of ARM9 and Linux operation system. This system is used in water quality monitoring system in the aquarium. Temperature, pH, conductivity, dissolved oxygen, ammonia nitrogen and other parameters are measured. The results show that the system has achieved the more stable acquisition speed and the higher transmission speed. And the system satisfied the requirements of the modern monitoring system.
