基于ZigBee-WiFi 混合网络的煤矿井下多参数传感器系统设计

摘要

现有井下无线参数采集传感器系统大多采用单一无线传输模式和采集单一参数，无法兼顾传输速率与使用能耗且安放不便。针对此缺点，设计了一种结合 ZigBee 与WiFi无线技术的多参数采集传感器系统，该传感器系统有效地结合了两种无线传输技术的优点，在降低使用能耗的同时提高了传输速率，且集成采集井下多种环境参数，具有布置灵活和扩展性强的特点。%The current wireless parameter acquisition sensor system used in coal mine was based on single wireless transmission mode and acquired single-parameter,which could not give consideration to both the transmission rate and the energy consumption,furthermore,it was complex to install.Aimed at these shortcomings,a multi-parameter sensor system based on Zig-Bee-WiFi mixed network protocol was designed for coal mine,which united the advantages of ZigBee and WiFi effectively. The system could reduce the energy consumption and meanwhile im-prove the transmission rate,and also could integrate many kinds of environmental parameters un-der the shaft,which characterized by flexible arrangement and outstanding expansibility.
