Railway Point Machine Control Automation Methods

In this article, the method of remote control of signals in stations with local control, which is used in railway stations, is considered. The analysis of control schemes of 2-, 3-, 4-, 9-wire direct current and 3-, 5-, 7-wire alternating current railway point machine, which are currently used in the electric centralization systems available in the Joint Stock Company “Uzbekistan Railways”, is presented. The article also presents the algorithm of the method of controlling the railway point machine using wireless communication with the help of constant and variable current microprocessor control modules. The method of controlling and controlling the railway point machine using wireless communication can provide the following advantages compared to the method of controlling and controlling the railway point machine using a wired connection: it reduces the operational costs for the equipment of the railway point machine; reduces human factors in local management of railway point machine; reduces maneuvering time; reduces the operating costs of stopping and moving the rolling stock. The safety of the method of controlling and controlling the railway point machine using wireless communication is mathematically based on Markov semi-chains.
