摘要
通过研究GPRS和ZigBee协议及WSN技术,提出了一种基于GPRS和ZigBee的矿井无线监测系统的设计方案。该方案借助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,利用系统及射频芯片CC2430设计多种类型传感器节点,采用簇-树网络拓扑结构,通过监测矿井下多种可燃性气体浓度和温湿度等环境参数的变化,为异常情况采取相应的措施提供决策依据。此方案较传统矿井监测系统具有功耗低、成本低、实时性高、布线方便等特点。
Based on the study of GPRS, ZigBee protocol and WSN technology, a new design of environmental monitoring system is put forward. By means of ZigBee protocol advantages in short - distance wireless commu- nication and GPRS network in long- distance data transmission, radio frequency chip CC2430 is introduced in the scheme to design sensor nodes, and the system uses cluster- tree topological structure. The decision for abnormal condition can be made rightly through detecting variation of parameters of combustible gases concen- tration and humiture from the mine. Compared with the traditional minel monitoring system, this scheme has characteristic of low power dissipation, low cost, high real - time and easy wiring, etc.
