摘要
为提升井下矿用带式输送机生产运行安全性,基于分布式光纤测温原理,构建大柳塔矿主斜井带式输送机温度监测系统。利用拉曼散射光原理和DTS技术实现温度监测和定位监测,温度监测精度可控制在±1℃以内,定位精度小于0.3 m;通过设置不同区域的预警温度,可实现带式输送机在不同位置处的分布式火灾预警功能,对电机、滚筒和CST等重点位置进行重点监测;根据用户需求的不同,系统可提供温升斜率、绝对温度以及相对温度等多种报警方式,从而提高监测预警的可靠性,实现整个运输巷的分布式、连续无盲区监测,具有较高的应用价值。
In order to enhance the production and operation safety of underground mining belt conveyor,the temperature monitoring system of main inclined shaft belt conveyor in Daliuta mine is constructed based on the principle of distributed optical fiber temperature measurement.Raman scattering light principle and DTS technology are applied to realize temperature monitoring and positioning monitoring with the temperature monitoring accuracy being controlled within±1℃and the positioning accuracy less than 0.3 m.The early warning temperature is set in different areas to realize the distributed fire early warning function at different positions of belt conveyor,and intensively monitor the key positions such as motor,drum and CST.According to the different needs of users,the system can provide a variety of alarm modes such as temperature rise slope,absolute temperature and relative temperature,so as to improve the reliability of monitoring and early warning and realize the distributed and continuous non-blind area monitoring of the whole transportation roadway,which has high application value.
