摘　　要：研究煤矿瓦斯爆炸准确预警问题,为及时准确的获取瓦斯爆炸预警信息,帮助人们采取有效的预防措施、降低人员伤亡和经济损失。由于有线监控系统本身受布线区域的限制,所以在建立瓦斯爆炸预警系统时,采用无线传感器网络技术,开发了以无线传感器网络为基础的预警系统。按照标准化生产的要求,系统的总体架构分为感知层、传输层、预警层和应用层。根据总体架构设计,系统应用了定向扩散路由协议对传感器所收集的数据进行有效传输。并有效的利用BP神经网络建立预警模型,结合无线传感器网络所收集的预警信息的数据,可对煤矿瓦斯爆炸做出准确有效的预警。Research on accurate early warning problem of coal mine gas explosion can acquire the early warn ing information of gas explosion timely and accurately and help people to take effective precaution measures against reducing the casualties and economic losses. Because the cable monitoring system itself is limited by wiring area, the wireless sensor network technology can used to develop the early warning system based on wireless sensor networks when the precaution system of gas explosion is established. According to the requirements of standardized production, the system＇s overall structure is divided into perception level, transport level, early warning level and application level. On the basis of the overall structure designing, the system applies the directed diffusion protocol to transmit da ta which are collected by sensors. Building the early warning model by the effective use of the BP neural network model and the collected data by WSN can make an accurate and effective early warning to the coal mine gas explo sion.
