The Organization of Effective Maintenance of Railway Automation and Telemechanics Devices in Low-Activity Sections

The article proposes a technological model for the organization of effective maintenance of signaling, centralization and blocking devices in low-active section.

Currently, the frequency of maintenance of infrastructure facilities in low-activity section is carried out with a regulated cyclic.

At the same time, the control of the technical condition, maintenance and repair of signaling, centralization and blocking devices depend on various parameters of the site in question, such as the intensity of train movement, traffic capacity and carrier capacity, the presence or absence of diagnostic and monitoring systems on the site and others.

The proposed model makes it possible to make a reasonable choice of technology for organizing the technical operation of train movement system on stretches and stations with low train traffic, taking into account the performance of safety functions assigned to them by infrastructure facilities, as well as compliance with established values of technical and economic efficiency indicators.

The technological model was developed using methods for assessing the risks of reliability and safety of alarm devices, centralization and blocking, methods for optimizing production processes and minimizing unproductive losses, modeling these processes using the method of functional networks.

The technological model is a decision-making tool for the application of a particular technology for the organization of maintenance of systems and devices for signaling, centralization and blocking in low-active section train traffic.

The practical application of the proposed model is realized by automatization of its provisions using appropriate information systems. Keywords: inactive sites, maintenance, alarm, centralization and blocking, technological model.
