Health degree monitoring and fault diagnosis system for coal mining machine

Abstract

The invention discloses a health degree monitoring and fault diagnosis system for a coal mining machine. The health degree monitoring and fault diagnosis system comprises an intelligent detection unit, wherein an output end of the intelligent detection unit is provided with a background controller; an input end of the background controller is provided with an information input module; an output end of the background controller is provided with an alarm, a display, a data storage module and a maintenance and repair module; and an output end of the data storage module is provided with a data analysis and judgement module. Data acquired by a data analysis and judgment module and data in big data are analyzed and compared to obtain fault data and health degree degradation data. An icon displaymodule compares received data with a normal range value and a fault degree range value to make texts and charts with higher readability, thereby facilitating check and alarm. During maintenance, health degree and fault information of the coal mining machine is transmitted to the maintenance and repair terminal, so that the maintenance and repair terminal can perform rapid maintenance or repair onthe coal mining machine, and delay in the work progress is avoided.

Description

technical field [0001] The invention relates to the field of coal mining machine monitoring systems, in particular to a coal mining machine health degree monitoring and fault diagnosis system. Background technique [0002] Most of the maintenance of traditional coal mining machines is after-the-fact maintenance. After-the-fact maintenance, as the name implies, refers to emergency maintenance without prior planning that is forced to stop when the shearer breaks down and is damaged. The countermeasures taken after the failure occurs are passive. Since there is no plan in advance, production may be stopped due to the long maintenance time. This phenomenon often causes greater losses to production and brings greater surprise to the repair work. , because the preparation work is not timely, the quality of the repair cannot be guaranteed. Regular maintenance, although it also relies on some relatively simple monitoring methods, mainly determines the maintenance cycle based on ex...

Problems solved by technology

The countermeasures taken after the failure occurs are passive. Since there is no plan in advance, production may be stopped due to the long maintenance time. This phenomenon often causes greater losses to production and brings greater surprise to the repair work. , because the preparation work is not timely, the repair quality cannot be guaranteed

Regular maintenance, although it also relies on some relatively simple monitoring methods, mainly determines the maintenance cycle based on experience. Regardless of whether the equipment needs to be repaired objectively, it must be repaired once at a certain time, that is, the daily maintenance and inspection of the shearer is carried out according to the plan , calibration and major and minor repairs, there is a waste of time and increased maintenance costs
