煤矿安全监控系统数据采集方式

摘要

This paper introduces the classification, basic composition and system topology of coal mine safety monitoring system, and compares the data acquisition methods of coal mine safety monitoring system. There are roughly three methods of data acquisition in coal mine safety monitoring system, i.e. master-slave (data acquisition by patrol inspection to sub-stations), multi-master (data transmission from node device initiatively upward) and their mixing methods. By comparing different data acquisition methods, the characteristics of different data acquisition methods are summarized, and the advantages and disadvantages of each method are obtained.%介绍了煤矿安全监控系统的分类、基本组成及系统的拓扑结构,对煤矿安全监控系统的数据采集方式进行了比较.煤矿安全监控系统的数据采集方式大致有3种:主从(以巡检的方式对分站进行数据采集)、多主(节点设备主动向上发送数据)及其混合方式;对比不同的数据采集方式,归纳出不同数据采集方式的特点,从而得出每种方式的优缺点.
