Підвищення показників готовності та відновлення систем керування рухом поїздів на основі збільшення глибини контролю

Abstract

Continuity of the processes of transportation by rail is determined by the operational reliability of train control systems. One of their most important parameters, which determine the operability and serviceability of control systems, is serviceability for regulating train traffic and performing shunting operations, as well as the ability to recover from failures. They are determined by availability factors and recovery rates, respectively. In order to increase these indicators in the published study, based on the latest scientific achievements, a model has been developed for assessing the depth of control of the functional parameters of train traffic control systems, which is carried out through functional tests. On the basis of scientific data that determine the relationship between the availability factor, the rate of recovery of technical means and the depth of their control, regularities have been established that determine the increase in the operational readiness and recovery rates of train traffic control systems when the scale and complexity of technological facilities change. A method has been developed that allows, on the basis of increasing the depth of control, to achieve an increase in operational readiness and the parameter of restoration of train traffic control systems, respectively, up to 30% and up to six times. Taking into account the correlation between the failures of train control devices and their delays, the indicated results make it possible to reduce the unproductive idle train up to 15%.
