ABSTRACT

One of the main problems of physical processes simulation which is used for operation support of technological equipment is that it should be solved repeatedly, parallel with the current technological processes. As input data for solving the simulation tasks the values of current processes parameters and equipment status. Most often the solution of the simulation tasks is realized on the basis of embedded systems we use. The results of simulation are used for the equipment diagnostics, generation of the controlling impacts, creation of forecasts and visualization of the current technological processes. Functions for processing of the simulation results are advisable to organize in other software subsystem. They are also executed repeatedly throughout all operating time of the equipment. At the same time it is very difficult to achieve equal speeds of software systems operation. The paper discusses methods of data transmission from the simulation subsystem to subsystems which perform their further processing. The cases where the speed of the processing of simulation results is less than the rate of their gaining are considered. The paper presents experimental results on the study of the data queue influence on the speed of the software subsystems, when a continuous data stream between subsystem is provided.

Keywords: computer simulation, asynchronous data interchange, real-time simulation software system
