煤矿井下便携式无线报警器的设计

The design of coal mine portable wireless alarm

针对目前煤矿井下报警器采用有线传输、检测参数单一、价格昂贵等不足,设计了一种基于无线传感网络的无线便携式报警器,测试并分析了该装置在不同环境下的传输规律,为其生产和推广提供了理论依据。该报警器具有同时检测多种气体、方便灵活、成本低廉等特点,为煤矿安全生产和矿工生命安全提供了有力保障。

Against coal mine alarm has deficiency of cable transmission, single parametric detection, expensive price,this paper presents design a wireless portable alarm based on wireless sensor network,test and analyze its transmission laws in different environments,which will provides a theoretical basis for pro-duction and promotion. This device has features of simultaneous detection of multiple gases,convenient and flexible,low cost and so on, which can provide a strong safe guarantee, for the coal mine production and the lives of miners.
