The Using of Electronic Document Management Tools of Technical Documentation for the Assessment of the Life of the Train Traffic Control Devices

A number of railways have posed repeatedly the requirements to provide a capability of shifting towards repair and recovery technology for maintenance of the systems due to trouble-shooting and forecasting of the device statuses and recording of the train traffic control devices based on their actual operation hours. At present, the integrated monitoring hardware permit to shift towards the above mode only for a number of devices equipped with the operation monitoring facilities. The goal of this work is developing a methods for calculating the resource based on existing technical documentation and data monitoring systems, without the additional cost of entering the source data. To this end, a method has been developed for constructing a model of the operation of a technical system for circuit solutions and protocols for its operation. Scientific innovation consists in developing a universal method that does not depend on the type of technical system, but is entirely determined by its description in a universal format. The paper proposes a method based on the graph and binary logic theory to receive data on the operation hours of all the system devices based only on available information and technical documentation for the system only. The proposed solution permits to obtain real data on the operation hours of automation devices without additional hardware costs, requiring no fitting of every system component with monitoring equipment. The integrated principles of technical documentation generation in a special format provide the prerequisites for intelligent processing of the data. After a traffic control system design was made in a special technical documentation format, a method has been developed to automate building of a real system model and analyze its operation. Owing to a combination of a computer modeling system and a record of real process operations implemented on a specific train traffic control system, a method has been developed to obtain data on operation of all the components at any point in time. And when an expected train schedule is built into the developed model, it is possible to plan a maintenance schedule in advance for a forthcoming period based on the actual condition without integration of new special hardware.
