矿用带式输送机监控系统的设计及应用分析

Design and Application Analysis of Monitoring System for Mining Belt Conveyor

以煤矿中使用的3台带式输送机为研究对象,设计了带式输送机监控系统。该系统共包含1个监控主站和3个监控分站,其中主站控制器型号为S7-1200型PLC,分站控制器型号为ET-200SP;变频器型号为西门子V20,拉绳开关、跑偏传感器型号分别为KBW-220L、THFKLT1-12-30,打滑开关、纵向撕裂保护装置型号依次为HSQ-726B2、BZL-220B。在软件程序的驱动作用下,根据各类传感器信号,可以实现设备的紧急停车、故障停车和正常停车。将系统应用到工程实践中,经6个月时间测试发现效果很好,设备故障停机时间由每月的54 h缩短至7 h。

Taking three belt conveyors used in coal mines as the research object,the monitoring system of the equipment was designed.The system contains one monitoring master station and three monitoring substations,of which the master station controller model is S7-1200 PLC,and the substation controller model is ET-200SP.The inverter model is Siemens V20,the pull rope switch and deflection sensor models are KBW-220L and THFKLT1-12-30,respectively,and the slipping switch and longitudinal tearing protection device models are HSQ-Under the driving effect of the software programme,according to the signals of various types of sensors,the emergency stop,fault stop and normal stop of the equipment can be achieved.The system is applied to the engineering practice,after 6 months time test found that the effect is very good,the equipment failure downtime from 54 h per month to 7 h shortened.
