井下粉尘监测预警系统探究

Research on Underground Dust Monitoring and Early Warning System

文章针对井下现有粉尘浓度监测方法单一、系统性差、预警系统不完善等问题,进行了井下粉尘监测预警系统探究,设计了自动监测与无线传输、自动监测与有线传输、自动监测与人工记录、手动监测与人工记录四层功能结构的分层次全方位粉尘质量浓度监测新方法,从产尘尘源、传播路径、影响人群三个环节分析了井下各测尘点的基础产尘机理,构建了基础产尘机理与粉尘质量浓度数据库,研发了基于DSP28335的智能预警系统,下设数据库子系统和PC主机子系统,为粉尘防控提供基础理论与现场数据。

Aiming at the problems of single detection method,poor systematicness and imperfect early warning system of underground dust concentration,this paper explores the underground dust monitoring and early warning system and designs a hierarchical and omnidirectional dust quality monitoring system with four functional structures:automatic monitoring and wireless transmission,automatic monitoring and wired transmission,automatic detection and manual recording,manual detection and manual recording.The new method of concentration monitoring analyzes the basic dust production mechanism of underground dust measuring points from three aspects of dust source,transmission path and affected population,builds the database of basic dust production mechanism and dust mass concentration,develops the intelligent early warning system based on DSP28335,and sets up database subsystem and PC host subsystem to provide basic theory and field data for dust prevention and control.
