Design and Application Analysis of Monitoring System for Mining Belt Conveyor
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.
