Fully-mechanized mining equipment digital mock-up analysis system and method based on geographic information system

Abstract

The present invention discloses a fully-mechanized mining equipment digital mock-up analysis system based on a geographic information system. The system comprises a geological database, a mining scheme constructing module, a geological environment analysis module, a digital mock-up analysis module and an equipment performance evaluation module. The present invention also discloses an analysis method using the system. The method comprises: establishing a mining area geographic information system according to the geological database; converting each coal seam mining scheme into a propulsion path and coordinate data of a fully-mechanized mining equipment in a geological environment, converting a cutting process scheme into an operating parameter of the fully-mechanized mining equipment, and associating the operating parameter of the fully-mechanized mining equipment with the propulsion path and coordinates; and extracting partial geographic environment information and the associated equipment operating parameter along the propulsion path, performing operation simulation and performance analysis by converting the partial geographic environment information and the associated equipment operating parameter into load and boundary conditions that are applied to a digital three-dimensional model of the fully-mechanized mining equipment, and performing comprehensive performance evaluation. According to the digital mock-up analysis system and method based on the geographic information system provided by the present invention, a comprehensive, reliable and effective analysis can be performed on the performance of the fully-mechanized mining equipment according to a complex geological environment; and a performance evaluation and warning can be performed on the fully-mechanized mining equipment.

Description

technical field [0001] The invention relates to a digital prototype analysis system and method of fully mechanized mining equipment based on a geographic information system, and belongs to the technical field of computer-aided design industry. Background technique [0002] The modern coal mining industry is developing rapidly in the direction of automation and less or unmanned mining. The three machines in the fully mechanized coal mining face: coal shearer, scraper conveyor and hydraulic support are the core equipment of modern coal mining technology. In the process of coal mining, safety is an eternal theme, and the safe and effective operation of fully mechanized mining equipment with three machines as the core is of great significance to the safety of the entire mining process. [0003] Fully mechanized mining equipment is a large and complex electromechanical equipment. During the development and design process, it is necessary to analyze and study its working performan...

Problems solved by technology

[0003] Fully mechanized mining equipment is a large and complex electromechanical equipment. During the development and design process, it is necessary to analyze and study its working performance to improve the reliability of the design. However, at present, the performance analysis is only performed on the typical working conditions of the equipment. The equipment needs to experience a complex and changeable working environment. The analysis of typical working conditions obviously cannot obtain comprehensive and effective performance results of fully mechanized mining equipment, and it cannot effectively analyze equipment performance in combination with the actual working environment
