Improvement of the information-measuring complex for diagnostics of traction power supply objects at high-speed traffic

Abstract

This paper considers the improvement of the information-measuring complex for diagnostics and monitoring of traction power supply equipment under high-speed traffic, which has several features associated with a multilevel hierarchical structure, spatial distribution of objects, energy modes and functional relationships. The analysis of the transmission and conversion of measuring analogue information into a digital one, considering the maximum frequency of the primary signal spectrum components according to the sampling and quantization parameters to determine the time of the signal converted into a digital form is made. Functional dependencies and an algorithm for measuring information processing, considering the multilevel structure of traction power supply, which allow increasing the reliability and accuracy of diagnosing the main objects in high-speed traffic, are obtained.

Application of the method of direct mathematical modeling to diamond-shaped contact lines

“…In the diаgrаm, the T аnd K tension is аpplied to the suspension wires, equаl to the double tension of the cаrrier cаble аnd the contаct wire respectively. The resilient elements аre rigid, independent of, the аmount of force аpplied to the retаiner, which, аccording to the results of experiments, is quite reasonable [6][7][8][9][10]. The tension of eаch of the wires will be considered constаnt, independent of the pressure of the current collector, аnd the loаd from the weight of the contаct wires evenly distributed аlong the spаn.…”

Investigation of biparametric resonance sensors with distributed parameters

“…that meet modern requirements when working in extreme operating conditions with increased dust, humidity, significant temperature differences, etc. [1,2,3]. A comparative analysis of the main characteristics of existing motion sensors shows that the most promising direction in solving the actual problem of more efficient use of monitoring and control systems is the use of biparametric resonant motion sensors (BRMS), which, by their properties (high reliability and stability of characteristics in extreme operating conditions, and also high output power) best meet the modern requirements of monitoring and control systems.…”
