For the provision of year round transport accessibility at realisation of the Northern Latitudinal Railway project it is necessary to consider not only difficult weather conditions of the region, but also the requirements to the organization of train operation and control of technical means condition on the designed railway line. The application of the integral complex of microprocessor systems of train dispatching allows creating a configuration of control areas between stations and realizing automatic control and monitoring of technical condition of railway automatics and telemechanics with the use of STD-MPK embedded module. Moreover, the system of technical diagnostics enables the application of various methods for digital processing of signals with the subsequent reception of qualitative feature space.
The paper is devoted to possibilities of application of a distributed optical sensor on the railway transport as a mean of rolling stock position control. The paper proposes numerical modeling of a signal of a phase-sensitive reflectometer for assessing influence of moving rolling stock vibration. A theoretical description supposes that the external vibrational influence creates an area of elastic deformation of a light wave guide cable and causes changes of phase relations of scattered radiation. As a result, the author presents that the frequency and the amplitude of the applied vibration affect to a greater extent on the signal of the distributed optical sensor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
