Minimization of the automatic machine structure process of accounting and control of railway automation and telemechanics devices

Abstract

The article explores the features of electronic document management of technical documentation of railway automation and telemechanics. A block diagram of an automaton model of technical documentation is developed. The proposed block diagram of a formalized model of technical documentation consists of matrices of external microoperations, internal microoperations, code creation for the following microcomponents. The number of internal states of the firmware is completely determined by the number of logic elements of the algorithms. The size of the matrices depends on the number of operators and logical conditions in the logic circuits of the algorithms. In this paper, a non-maximal group of compatible elements of logic circuits of algorithms is used as a microcommand, which led to the simplification of the matrix of the circuit of the firmware automaton. In the considered method of forming the maximum groups of compatible elements of logic schemes of algorithms, micro operations included in each micro command are performed simultaneously in one microtact. The structure of the firmware of the machine is simplified due to the transition from simple to complex micro-ops.

Development of a route setting model in the dispatching centralization system

“…When supplying rail traffic in scenarios with very poor reliability, these systems are prone to errors. Small errors might result in significant financial losses and occasionally even deadly mishaps [14][15][16][17][18][19][20][21]. Thus, the safety degree of automation and remote control systems that guarantee the security of train movement should be examined.…”

“…The route setting based on the artificial neural network model [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] is shown in Figure 1, accounting for the train's moving stations. We will construct the neuron set in two layers in this instance [34][35].…”

“…The data transmission networks (DTN) distributed automated control systems (ACS) [14][15][16][17][18][19][20][21][22][23] is the source of information regarding the establishment or dissolution of the movement structure.…”

Functions of the interlocking system on mixed traffic lines

“…Every station has many pairs of control points installed on the approach section. It is found that the intervals between these locations correspond to the electrical centering system's mode entry times [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. When the rolling stock approaches the station, the first of the two control points notifies the interlocking system.…”

“…2, a -For high-speed trains, the following expressions (4), ( 5), (6), and ( 7) are used to calculate the distance between the first and second control points in the figure as well as the rolling stock's time of movement. High-speed train braking times are expressed as follows: (4) for high-speed train braking times between 0 and 108 km/h, (5) for high-speed train braking times between 108 and 350 km/h, and ( 6) and ( 7) when braking is an expression of the path [15][16][17][18][19][20][21][22][23][24].…”
