Technical control of digital code autoblock system
Journal Title: Електромагнітна сумісність та безпека на залізничному транспорті - Year 2017, Vol 1, Issue 13
Abstract
The purpose of the work is to identify the characteristic features of the technical control of the digital code autoblock system, their advantages and disadvantages, to analyze the possibility of using them to diagnose the condition of the autoblock devices and to set tasks for the develop-ment of new diagnostic complexes. To achieve this goal, a theoretical analytical method and a method of functional analysis were used. The analysis of existing and prospective means of remote control and technical diagnostics of auto-blocking devices showed that existing systems have insufficient information content, they are aimed mainly at controlling discrete parameters, which, in turn, does not allow them to build a subsystem of decision support on their basis. It was proposed to use the centralized-distributed principle of diagnostic data processing to develop a new system of technical diagnostics, to in-clude a decision support subsystem in their structure, which would reduce the amount of effort required to service autoblock devices and shorten the time for recovery after the occurrence of damage . As a result of the research, it was revealed that the existing means of automatic control of automatic blocking can’t provide a full assessment of the condition of the distillation devices of signaling and blocking, and proposed criteria for the development of new systems of technical diagnostics with increasing the number of diagnostic information and its automatic analysis. The results of the analysis can be used in practice to select the means for technical control of autoblock devices, as well as for the further development of autoblock diagnosis systems, which allows a gradual transition from a scheduled preventive maintenance model to maintenance ac-cording to the actual state of the monitored devices.
