Complex simulation model of functioning mine telecommunication system using Power Line Communication technology

Abstract

This paper considers a modern development of telecommunication systems as a part of electrical complexes of underground facilities, namely, application of PLC technologies for complexing electrical systems. A description is provided of the main tool of experimental studies of such systems, a simulation model of operation, its structure, development sequence and main elements, as well as an experimental validation of the model.

The proposed model will allow solving a wide range of problems in the process of studying telecommunications systems and power supply systems for underground structures. Model development included the formulation of complex research tasks, the creation of the conceptual model, the formation of a set of requirements for the modeling algorithm, the development of a mathematical model, creating a simulation program in C++ with the use of JBuilder, the company Embarcadero version 10.3, as well as the verification of the simulation model. Based on the considered structure of the PLC network, it is proposed to include an information generation module, a connection module, a transmission line module, a modulation, encoding and decoding module, an information processing and noise reduction module, a subscriber module and a performance evaluation module in the model of integration of power supply and telecommunications systems for underground structures. To solve the problem verify the model was developed methods of research the effectiveness of various algorithms for transmission power supply networks underground structures, allowing an informed choice of data transfer methods and rational selection of the non-necessity to implement the methods selected equipment and conducted a series of experimental studies on real industrial underground facilities.
