Application of Closed Circuit Television for Highway Telematics

The article presents questions connected with the transport telematic systems. Both analogue (CCTV) and TCP/IP controlled (CCTV IP) visual monitoring system are presented. New concepts of technical and functional solutions are also discussed, aimed to improve the operational effectiveness of integrated control and surveillance centres managing the transport telematic systems.

Modelling of power supplies reliability in aspect of their technical and functional state

Abstract The article presents issues related to the modeling of reliability of power supply in terms of their technical and functional condition. There are designated relations allowing to determine the probability of staying the power supply in the state: full suitability, incomplete suitability and unsuitability. There is also examined the impact of time restore of the state of full suitability for the value of the probability of staying the power supply in the state of incomplete suitability.

Reliability and maintenance analysis of CCTV systems used in rail transport

Abstract CCTV systems are widely used across plethora of industrial areas including transport, where their function is to support transport telematics systems. Among others, they are used to ensure travel safety. This paper presented a reliability and maintenance analysis of CCTV. It led to building a relationships graph and then Chapman–Kolmogorov system of equations was derived to describe it. Drawing on those equations, relationships for calculating probability of system staying in state of full ability SPZ, state of the impendency over safety SZB1 as well as state of unreliability of safety SB were derived.
