Study on remote real-time interactive fault diagnosis technology for coal mine hoist
Coal mine hoist is very important to coal mine safety production.In order to ensure the safe and stable operation of the hoist,the remote real-time interactive fault diagnosis technology of the coal mine hoist was studied.A remote real-time interactive system architecture of hoist was proposed,which was composed of four parts:data perception and processing,real-time monitoring platform,re-mote supervision and remote maintenance.On the basis of summarizing the field experience,six methods suitable for eliminating hoist faults were proposed,including principle judgment method,ap-proximation method,fault law method,comparison method,hypothesis method and system thinking method.In addition,regular maintenance of equipment based on workflow and auxiliary evaluation method of equipment operation status based on support vector machine were also proposed.The field application shows that the system runs well and is stable and reliable.It can improve the information management level of coal mine hoist.
