Coal cutter state monitoring method based on black box

The invention relates to a coal cutter state monitoring method based on a black box. The method is implemented through a coal cutter state monitoring system based on the black box and a coal cutter state monitoring method based on the black box. The coal cutter state monitoring system based on the black box is composed of a hardware part and a software part, the hardware part comprises the coal cutter black box and an intrinsic safety type vibration acceleration sensor provided with a coal safety certificate. The software part mainly comprises data storage software and data analysis software. The coal cutter state monitoring method based on the black box mainly comprises state parameter acquisition, state parameter storage, state parameter analysis and coal cutter working state monitoring. The coal cutter state monitoring method is complete in monitoring range, multiple in monitoring parameters and good in timeliness, and data storage is convenient.
