Abstract: This article describes a methodology for evaluating the effectiveness of a rail vehicle condition monitoring system in terms of requirements for the hardware part of the system. The requirements contained herein should be met in the construction of any system intended for installation on a rail vehicle. They concern environmental requirements based on applicable standards and functional requirements related to the measurement properties of the equipment used, which will guarantee the correct operation of the system, and consequently its high efficiency and the reliability of the diagnostic information obtained.1. INTRODUCTION
When designing any technical system, we must take into account the scope of the system, defining its limitations, and define its constituent elements and their necessary mutual couplings. The constituent elements of a technical system can be divided into six groups, which include: electronics, mechanics, electromechanics, thermomechanics, electro-optics, and software. The first five groups can be called the system hardware.
The process of monitoring the condition of rail vehicles is also a technical system containing the components listed above. This article will be devoted to the methodology for evaluating the effectiveness of such a system from the point of view of its hardware part, which will consist of: sensors, cabling, a data acquisition unit, a positioning system, and data transfer. This involves formulating essential requirements related to their functioning and capabilities. We will evaluate the effectiveness of the monitoring system based on an assessment of the system’s capabilities in relation to the applicable regulatory requirements for the conditions in which the system will operate and the results of simulation tests carried out on a simulation model of the vehicle.
We will deal in turn with the environmental conditions in which rail vehicles are operated, the system architecture and its operating mode, the selection of sensors for the system, and the data transmission parameters in the system. (…)
