Context. Development of models of automated control systems for ventilation, designed to prevent emergencies in the mine ventilation<br />network, is considered in the paper. The task of research and implementation of software modeling tools that allows the execution of<br />experiments with real science-intensive objects is being solved.<br />Objective is to improve effectiveness of the real-time model of a mine ventilation network by developing and optimizing a method for<br />organizing a computational process that considers the different frequency parameters of the models.<br />Method. We proposed and investigated the algorithm of scheduling and implementation of the cyclic schedule for the model of the<br />dynamic real-time object, presented by the mine ventilation network. We analyzed the mathematical model of aerodynamic processes and<br />classified it as a stiff real-time system. Calculations of phase variables with varying velocities are performed by splitting the original algorithm<br />into parallel flows in the program model. Numerical integration of the differential equations system of the mathematical model of the object<br />is performed in accordance with the algorithm of static priorities and controlled using the time scale. The schedules feasibility is determined<br />for the target object limited parameters. The scheduling algorithm considers the time parameters of software tools for both uniprocessor and symmetric multiprocessor systems.<br />Results. Analysis of simulation results of the proposed model with using cyclic schedules shows the correspondence of the obtained<br />modeling results to the reference one.<br />Conclusions. The main advantage of the model is the performance increase when performing data processing due to the reduction of the<br />CPU usage time. Implemented cyclic schedule algorithm for real-time simulation platform can be used for development of control system for<br />technological and emergency modes of ventilation in mines. |
