Problems solved by technology

The process of coal sample sampling must not only comply with national standards and industry standards, but also meet the management requirements of power generation companies. The national standard requires that the top of the coal transport vehicle be divided into 18 areas for random area sampling. Many problems were found during the implementation. A lot of power generation compani

Abstract

The invention discloses a coal conveying vehicle sampling point selection method and system based on exclusive randomness. The method comprises the steps that S1, acquiring the size of a coal conveying vehicle and the number N of sampling points; s2, evenly dividing the roof area of the coal conveying vehicle into 18 areas; s3, selecting a sampling area, when N is smaller than or equal to 3, determining that the adjacent sampling area of any selected sampling area cannot be selected any more, and when N is larger than 3, selecting the sampling area according to the condition that N is equal to3, and then randomly selecting N3 different sampling areas from the remaining 15 areas; and S4, randomly generating sampling point coordinates in the selected sampling area. The system comprises a memory and a processor for operating the method. According to the embodiment of the invention, an exclusive random algorithm is adopted, so that the randomness of the positions of the vehicle sampling points is ensured, the positions of the sampling points cannot be concentrated in adjacent areas, the representativeness of the coal sample is improved, and the sampling result better conforms to the actual situation.

Description

technical field [0001] The invention relates to the field of sampling coal-carrying vehicles in thermal power plants, in particular to a method and system for selecting sampling points of coal-carrying vehicles based on exclusionary randomness. Background technique [0002] At present, fuel accounts for about 70% of the cost of power generation in thermal power generation companies. Minimizing fuel cost and improving corporate profitability are the key issues for every power generation company. The settlement of fuel is based on the results of sampling and testing of coal samples. The process of coal sample sampling must not only comply with national standards and industry standards, but also meet the management requirements of power generation companies. The national standard requires that the top of the coal transport vehicle be divided into 18 areas for random area sampling. Many problems were found during the implementation. A lot of power generation companies still use...
