Digital coal stocktaking system and digital coal stocktaking method

Abstract

The invention relates to a digital coal stocktaking system comprising a laser scanning module, a spatial positioning module, an intelligent data acquisition module, a data transmission module, and a terminal processing module. The laser scanning module sends acquired surface shape information of a measured object to the intelligent data acquisition module. The spatial positioning module sends acquired spatial position acquisition of a bucket wheel machine to the intelligent data acquisition module. The intelligent data acquisition module sends the surface shape information and the spatial position acquisition to the terminal processing module through the data transmission module. The terminal processing module obtains the surface shape and three-dimensional coordinate data of the measured object according to the surface shape information and the spatial position acquisition, and then carries out three-dimensional modeling and displaying on a coal pile. According to the invention, a coal stocktaking instrument mounted on a portal frame is wide in range of scanning, and is not constrained by the coal height of a coal yard in scanning. A GPS differential system for spatial positioning and the wireless network transmission technology are adopted. Compared with other schemes, the positioning accuracy and the real-time performance of data transmission can be better guaranteed.

Description

technical field [0001] The invention relates to a digital coal yard based on GPS (BD) differential positioning and laser scanning technology, in particular to a digital coal panning system and method. Background technique [0002] At present, most of the existing laser pan coal instruments are portable laser pan coal instruments, fixed coal pan instruments, etc. The portable coal-panning instrument has existed in the market for a long time. It is slowly transformed from engineering measuring instruments, while the fixed coal-panning system is a product specially developed for large-scale coal field inventory. From theory to practice, it has never been an immature product. It has a very deep background of the times to become the most advanced coal-coal method in thermal power plants. Every year, the cost of coal-fired power plants accounts for about 70% of the total operating costs. Only by accurately understanding the monthly coal consumption indicators can we achieve more ...

AI Technical Summary

Problems solved by technology

[0007] This technology is to install the coal panning instrument on the cantilever of the bucket wheel machine. If the pile of coal in the coal yard is too high, the cantilever of the bucket wheel machine cannot be lifted to a higher place, and the coal panning instrument cannot perform normal coal panning.

In addition, when the bucket wheel machine needs to move upward on the guide rail during coal panning, the cantilever will vibrate, which will bring errors to the coal panning results, and the scanning range of the pan coal instrument installed on the cantilever is small, and the cantilever needs to be lifted to a certain position during coal panning. height, it will bring a workload to bucket wheel operators
