Abstract
Requirements to the sports ground illumination have been analyzed. As the result of the analysis of the latest publications dealing with the optimization of the illumination-technological parameters of the sports grounds illumination it was found, that this problem has not been investigated enough. Generally the optimization of the light source luminous flux has been studied as well as taking into consideration the light reflection and its scattering on the general illumination of the object. There are publications, which deal with the application of the parallel computation methods for rapid calculation of illumination according to the known layout of the outdoor facilities distribution. But the papers devoted to calculation of the optimal floodlights location, taking into account different additional requirements, in fact are not available. The optimization algorithm of the sports grounds illuminating devices distribution, which is based on the computer analysis of the illumination matrix of the sports ground by a single floodlight, has been proposed. The amount of computer memory needed to store all matrixes describing the sports ground illumination by one floodlight. The basis of analysis is the creation of illumination matrix for all possible places of distribution (on the towers and stadium roofs) and several types floodlights direction, taking into account standard requirements dazzling, uniform illumination and the sports grounds functioning regime. Precautions as to the elimination from the matrix calculation the disadvantageous parameters floodlight are presented. The main characteristic of the algorithm is the creation of the total matrix of the sports ground illumination as the sum of matrixes successive approximation to the optimal result, basing on the analysis of minimum and maximum level of illumination of the total matrix and every followed, which is added. After computer optimization the maximum, minimum and average levels of the sports grounds illumination are determined and compared with those acceptable parameters. Additional condition of optimization is, as a rule, providing of the sports ground shadowless illumination, which is guaranted by the location of the floodlights distribution along its path. The optimization process can be similar to other floodlight types and their distribution places. Basing on the mentioned algorithm the Pascal software in Delphi has been developed and the example of calculation of the symmetric four-tower system with main results of software icons has been presented.
