Investigation of the quality of functioning of a quadrature signals receiver of a continuous automatic cab signaling on records of real signals and interference

Abstract

Ensuring a safe transportation process is impossible without the use of complex systems for interval regulation of train traffic. In particular, such a system is a continuous automatic cab signaling (CACS) where signals are affected by various kinds of interference, leading to system failures. To reduce the number of system failures, the authors previously proposed a quadrature signal receiver of CACS (QSR of CACS). The article presents the methodology and results of an experimental study of the quality of the functioning of the QSR of CACS on records of real signals and interference. A simulation model of the test facility has been developed in the Simulink simulation environment. The study showed that the QSR of CACS provides reliable reception of CACS code signals with a low level of interference. However, it needs to apply additional measures in it to reduce the influence of impulse noise.
