Simulating the Various Subsystems of a Coal Mine

A set of simulation models of various subsystems of a coal mine was developed with the help of a new visual interactive simulation system of technological processes. This paper contains a brief description of this simulation system and its possibilities. The main possibilities provided by the simulation system are: the quick construction of models from library elements, 3D representation, and the communication of models with actual control systems. These simulation models were developed for the simulation of various subsystems of a coal mine: underground conveyor network subsystems, pumping subsystems and coal face subsystems. These simulation models were developed with the goal to be used as a quality and reliability assurance tool for new process control systems in coal mining.

DCOM Based Group Communication for Ship Motion Virtual Simulation

Virtual reality based visual interactive simulation system is proposed and completed, which applied integrated intelligent control to ship steering and main engine. For the multipoint communication of the proposed distributed visual simulation system, a DCOM based communication model is discussed. The group communications is divided into three layers from bottom to top. Based on static and dynamic combined algorithm, a dispatcher using centrality load balancing is also presented.
