Analysis and Design of On-Line Monitoring and Fault Prewarning System for Mine Ventilator

Abstract

According to the present state that traditional regular repair methods are always adopted for mining equipment maintenance, this paper puts forward a method of installing various sensors on the equipment which are combined with computer and signal analysis technology so as to realize on-line monitoring, fault prewarning, and remote release. This paper analyses the common faults of mine ventilator and their characteristics, selects the vibration sensor and its mounting points based on the characteristics of the fault signal, selects the signal acquisition cards based on equipment operating conditions and analysis parameters accuracy, builds up the hardware and software platform, completes the design of system function module and data flow, and achieves modularization programming for the whole software system by combining labVIEW and database. This system realizes the condition-based equipment maintenance so that informatization and automation can be achieved in equipment management.
