Fixed coal inventory method and system of closed coal yard

Abstract

The invention discloses a fixed coal inventory method of a closed coal yard for solving the problem of inaccurate coal inventory in the prior art. The method comprises the following steps: S1: collecting preset three-dimensional information of a corresponding coal pile through a plurality of rotating cloud decks fixedly installed at preset positions and laser range finders installed on the rotating cloud decks; S2: obtaining the coal quality information corresponding to the current coal pile; S3: calculating the three-dimensional model information corresponding to the current coal pile; and S4: displaying the three-dimensional model information corresponding to the current coal pile on a preset platform according to a preset display manner. By adoption of the method, the rotating cloud decks are fixedly installed at preset positions of the closed coal yard, thereby improving the scanning precision, reducing the workload of a worker and realizing real-time coal inventory, as a pluralityof rotating cloud decks and laser range finders are arranged, block scanning and data integration are performed to eliminate superposed information and useless information, and the effects of non-blind area of coal inventory and high coal inventory precision are achieved at last.

Description

technical field [0001] The invention relates to the technical field of closed coal yard monitoring, in particular to a large-scale closed coal yard fixed coal coiling system and method. Background technique [0002] Coal-burning costs of coal-fired power plants account for about 70% of their total costs. Accurately understanding the inventory of coal-fired stocks in the production and operation process and managing them scientifically is an important link for coal-fired power plants to save energy and reduce coal-burning costs . Due to the time-consuming, labor-intensive and extremely error-prone traditional manual coal-coaling, it has been basically eliminated by power plants in recent years. Panmei Yipan Coal plays an important role in coal yard management. [0003] However, there are obvious defects in the fixed coal coal method on the market today: [0004] (1) The coal pan instrument is installed on the walkable coal yard machinery, such as coal yard stacker and recl...

AI Technical Summary

Problems solved by technology

The installation method of this kind of coal detector can effectively reduce the blind area of ​​scanning, but there is a fatal flaw, that is, the smooth operation of the coal detector on the track cannot be guaranteed; the trolley must run without any bumps on the track, which requires Guarantee the absolute horizontal position and absolute flatness of the track, because any small fluctuations will reduce the accuracy of the final coal, and the scanning speed is slow, it needs to be walked to complete, and it cannot be real-time coal in the real sense, so this This mode of operation has not been widely promoted in the current detection of coal in coal yards, but it is only an ideal working mode
