基于无线自组网络的矿井环境数据采集设备设计

Design of mine environmental data acquisition equipment based on wireless ad hoc networks

针对目前煤矿安全监测系统大多采用固定的有线传感器组成的网络而存在监测盲区的现状,提出了一种基于无线自组网络的矿井环境数据采集设备的设计方案,详细介绍了低功耗无线自组网络的设计。该设备以ATmega16L单片机作为主控芯片,通过射频收发芯片NRF24L01实现无线收发功能,采用平面式网络拓扑结构及按需路由方式,实现了对矿井环境数据的采集及预警,减小了监测盲区,且具有较高的安全性和可靠性。

For status that most coal mine safety monitoring and control systems adopt fixed and wired sensor network which has blind spots, the paper proposed a design scheme of mine environmental data acquisition equipment based on wireless ad hoc networks, and introduced design of low-power wireless ad hoc networks in details. The equipment takes ATmegal6L signle-chip microcomputer as master chip, achieves wireless transceiver by RF transceiver chip NRF24L01, and uses planar network topology and ondemand routing mode. It realizes collection of mine environmental data and early warning, reduces monitoring blind spots, and has higher security and reliability.
