Diagnostic and Control System of Automatic Locomotive Signaling System Based on Microprocessor Elements

In this article, a wireless data transmission and reception module, a software for archiving and protocolizing measured parameters, and a complex modular control system with a universal digital programmable microprocessor have been developed to determine the external and internal interference affecting the automatic locomotive signaling system on railway sections in a special laboratory car. It was possible to transfer the obtained results online from a special laboratory car to the site electromechanic during movement, and a software interface window was developed for car operators and engineers. The developed system was tested on the high-speed section of the Uzbek Railways. In order to check the reliability of the device, the green (Z), yellow (J) and red-yellow (KJ), red (K) and white (B) code signals of automatic locomotive signaling were checked separately for each process and oscillogram results were obtained using a laboratory stand. In addition, the structural block diagram of the automatic locomotive signaling signal measuring stand has been improved. Based on the existing expressions, an optimal graph of the height from the rail to the locomotive receiver coil and the operating frequency range in order to reduce the disturbances in the rail circuits was developed.
