Description

Operation behavior tracking system for coal mine multi-source sensing Technical Field The invention belongs to the technical field of coal mine operation behavior monitoring, and particularly relates to an operation behavior tracking system for coal mine multi-source sensing. Background In a complex working environment of a coal mine, in order to improve the safety and the working efficiency of underground working, the prior art generally adopts a multi-source sensing technology to track and monitor the working behaviors of miners. The action data of miners are collected through wearable equipment, a positioning system, a camera device and the like, and management targets such as operation dangerous behavior early warning, fatigue state identification and personnel behavior standardization are achieved by combining equipment operation parameters. Meanwhile, aiming at the operation state monitoring of underground movable support equipment, the equipment performance is also detected in real time by means of pressure sensors, inclination sensors and the like so as to ensure the equipment stability and the coal mine supporting capacity. However, most of such techniques focus on the personnel behavior itself or the device state itself, and do not sufficiently pay attention to the coupling relationship between the device operation region configuration and the personnel operation behavior. In an actual underground operation environment, underground movable support equipment is usually installed in different mining area environments by different assembly personnel, and is influenced by factors such as roadway structures, terrain height differences, space limitation and the like, and unavoidable differences exist in the aspects of working space width, effective operation height and the like in equipment operation areas. It is generally recognized in the art that these differences do not affect operation and are therefore not quantitatively identified or normalized. However, those skilled in the art find that, when the miners perform the operations of adjusting the stent pressure or controlling the stent inclination, the posture adjustment is closely related to the layout of the operation area, and when the operation area is unreasonable, the miners deviate from the standard operation posture for adapting to the space, so that deterioration of the equipment degradation response, such as aggravation of stent pressure deviation, slow inclination recovery, etc., is caused, and the quality of the operation is reduced and the potential safety hazard is increased. Therefore, the prior art has the core technical defects of uncontrollable configuration of an operation area, lack of evaluation basis and no follow-up quantification standard, so that the deviation of the operation posture of a miner cannot be effectively prevented, and the running quality of underground movable support equipment cannot be stably ensured at the source. Disclosure of Invention The invention aims to provide an operation behavior tracking system for multi-source sensing of a coal mine, and aims to solve the problems in the background technology. The invention is realized in such a way that an operation behavior tracking system facing to multi-source sensing of a coal mine comprises: the data screening module is used for screening a plurality of first samples which are consistent with the background of the current coal mine operation area and different in working time length of miners from the operation behavior database; The data analysis module is used for analyzing each first sample and analyzing whether a preset mode exists or not, wherein as the working time length is increased, the posture change amplitude of a mineworker in an operation area of the underground movable support equipment is gradually increased and is stable, and meanwhile, the degradation feedback comprehensive index of the underground movable support equipment is gradually optimized and is stable; the mode identification module is used for selecting an miner with the best degradation feedback comprehensive index change as a reference miner if the existence of the preset mode is determined, finding a plurality of second samples which are consistent with the background of the current coal mine operation area and have the working time longer than the specified time length and work by the reference miner from the database, and analyzing whether the coupling relation exists between the equipment operation area configuration change trend and the gesture change amplitude change trend in the second samples; And the configuration adjustment module is used for screening second samples with the gesture change amplitude lower than a preset amplitude and the degradation feedback comprehensive index lower than a preset requirement from a plurality of second samples as standard samples if the coupling relation is determined, and adjusting the current underground movable support equipment ope
