Abstract

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.

Description

technical field [0001] The invention relates to a method for monitoring the state of a coal shearer based on a black box, in particular to a method for monitoring state information such as working parameters of a coal shearer motor, oil cylinder load, vibration characteristics, and posture based on a black box. Background technique [0002] The fully mechanized mining face is the back mining face equipped with comprehensive mechanized equipment underground in coal mines, and it is the most advanced and most complicated working link in coal mine production. A standard fully mechanized mining face generally consists of 200 to 300 pieces of equipment. The core equipment includes coal shearers, scraper conveyors, hydraulic supports, reloaders, crushers, and belt conveyors. Restrict and coordinate with each other. [0003] There are restrictive factors such as high gas, large inclination, hard top coal, and complex geological conditions in the mine. To achieve the development go...
