煤矿井下局部风机监控系统研究

摘要

This study aims at designing a monitoring system which could automatically monitor main indicators of local ventilation of coal mine underground.This system was designed via diagnosis of key fault units in ventilators and analysis of pan-alarm and control technique.It is based on a single chip（SCM） MSP 430 with multi-sensors and peripheral circuits.to realize a real-time data transmission of environmental parameters such as mine gas concentration and air quantity,to communicate with host computers in control center,achieving remote monitoring.This intelligent system could reduce the possibility of mine gas explosion caused by stuffiness and thus ensure the safety in modern coal mine production.%通过对煤矿局部通风关键故障单元、检测和报警参数等进行分析。设计了以单片机作为核心,配合各种传感器与外围电路,自动监控煤矿井下局部通风各项指标的系统。实现了局部风机开机、停机、检测、调速的全面智能化,采用实时在线监测数据传输,实现集中和远程监控。该系统提高了井下安全生产的可靠性,可以满足现代化矿井安全监控的需求,具有实用和推广价值。
