Reliability analysis of the power supply system of closed-circuit television system used at a highway toll collection point

摘要

The article presents issues concerning the power supply systems of closed-circuit television systems used at a highway toll collection point. The general diagram of the power supply system was presented, and then the reliability analysis was conducted. This enabled to develop a relationships graph, on the basis of which the Chapmana??Kolmogorov system of equations describing it was created. On this basis, it was possible to set the relationships allowing to calculate the probability values of the systema??s staying (in symbolic terms) in the following functional states: of full ability SPZ, of non-full ability SZB1 and SZB2, and of unfitness SB.
