| Description |
An improved algorithm for modelling the time characteristics of the freight traffic working faces is described in article. Using existing technology simulation algorithms need to use conditional constructions, and other variables, which increases the times of working program simulates the process by computer and complexity algorithms of human perception. The idea of modelling the flow of coal from the working face is to use the properties of elementary linear functions together with the operators of rounding to whole pseudorandom numbers with a Gaussian distribution for the subsequent value of the generalized function at only a certain present. The proposed algorithm uses a property of a linear function y = - (x-l) y = 0 when x = l and y = 1 when x = 0, which allows you to escape from conventional structures and not introduce additional variables. The function Y (t) at any given time can be equal to either the first part of the sum Y (t-l) * ceil (z-zn) or the second (- (Y (t-l) -l) * (- (ceil (z -Zo) -1)), because the the multipliers Y (t-l) and - (Y (t-l) -1) take the opposite binary values for the same value of the function Y (t-l). The first part of the sum multiplier ceil (z-zn) is equal to one for z> zn, which determines the probability of a lack of freight traffic in the interval 2 determimng the probability of the start of the interval availability of freight. The algorithm allows to simulate the flow of coal from the working face in the simulation model of the transport network of the mine. The drawings, which are given in the article, show receipts of coal from two working faces and merging these streams after passing through the conveyor chain. In the simulation of two or more working faces on modern PCs use advanced algorithm reduces by about a third the time their outputs, which is particularly important for modeling modes of mine transport network as a whole. The accuracy of the calculation of the characteristics of mass flows of the proposed algorithm is not lower than the existing one. The proposed algorithm combined with the indirect method of determimng the flow patterns of coal working faces an opportunity to assess the real-time efficiency of the conveyor and control processes for the transportation of coal, in particular, the maximum energy efficiency, for example, by means of variable speed drive. Предлагается алгоритм моделирования потока угля из очистного забоя, приводятся результаты его работы в составе имитационной модели транспортной сети шахт. |
