基于ZigBee与数传电台的矿井环境检测系统节点设计及其组网方案

针对因煤矿井下环境复杂造成无线传感器网络无法有效地远距离传输信息的问题,提出了一种基于ZigBee无线传感器网络与数传电台的矿井环境检测系统的设计方案,给出了系统总体结构,介绍了以CC2430为核心的传感器节点和网关节点的设计,阐述了适合于矿井环境的ZigBee无线传感器树形网络组网方案的实现。实际测试结果表明,该系统采用ZigBee无线传感器网络与数传电台相结合的通信方案是切实可行的,有效解决了低功耗、远距离传输、高可靠性方面的问题;对节点进行编号的组网规则使网络拓扑结构更具有针对性,提高了节点的精确定位功能,降低了井下作业的危险性。

Node Design and Networking Scheme of Mine Environmental Detection System Based on ZigBee and Data Radio Station

In view of the problem that wireless sensor network can't make remote transmission because of complex underground situation,the paper proposed a design scheme of mine environmental detection system based on ZigBee wireless sensor network and data radio station.It gave general structure of the system,introduced design of sensor node and gateway node which taking CC2430 as core,and expounded implementation of networking scheme of ZigBee wireless sensor tree network.The test result showed that the system uses communication scheme combing with ZigBee wireless sensor network and data radio station is feasible,which solves problems about low power,remote transmission and high reliability,and networking rule of node numbering makes topology of network has pertinence,which improves accurate position function of node and reduces risk of underground operation.
