Systems of Automatic Control of the Technical Condition of the Rolling Stock During the Movement of the Train

Abstract

The article deals with the improvement of automatic control over the technical condition of rolling stock during train movement. The consequences arising from a malfunction of axlebox node are described, the principles of detecting the emergency heating of the axleboxes are justified. The main detectors of infrared radiation and their characteristics used in temperature control systems are listed. The expediency of updating these devices on Ukrainian railways is substantiated. The paper analyzes both current domestic (PVNAB-3, ASDK-B) and foreign diagnostic control systems, concluding that the rear wall of the axlebox housing is the most rational control area. The authors emphasize the necessity of modernizing Ukrainian systems by implementing microprocessors and full computerization to enhance safety and prevent accidents.
