Prospects of Using Technologies for Adaptive Control of the Latent Period of Accidents in Facilities of the East-West Transport Corridor
摘要
It is shown that increasing the level of safety of the East-West transport corridor first of all requires developing technologies, means and a system for adaptive control of the onset of malfunctions on rolling stock, railroads, bridges, tunnels and key communications along the entire route. At present, the number of unexpected accidents in rail transport largely depends on the qualification of the driver, who intuitively determines the current technical condition of the object and the beginning of possible accidents on the basis of accumulated experience and information received from control systems. Despite this, sometimes the driver’s decision is delayed and accidents occur. Usually, these accidents occur as a result of emergence and development of various malfunctions. Here facilities enter the latent period of an emergency state, noises emerge that are correlated with the controlled signal \(g\left(t\right)\) , the dynamics of facility operation changes, causing the spectra of the useful signal \(X\left(t\right)\) and the noise \(\varepsilon \left(t\right)\) , which is filtered according to traditional technologies, to change as well. In this paper, while allowing the traditional control technology to stand, we additionally propose an adaptive technology for controlling the beginning of the latent period of the accident. Here the estimate of the relay cross-correlation function between the following the useful signal \(X\left(t\right)\) and the noise \(\varepsilon \left(t\right)\) is used as an informative attribute. In addition, the use of positional binary technology is considered.
