The paper presents questions connected with the transport telematic systems. One of the most important attributes of telematic systems is the data transfer and transmission. The transmitters and receivers applied require reliable power feeding sources. Therefore, buffer power supply units are used that cooperate with backup power sources, such as rechargeable electrical power sources (batteries).
Theory of the systems reliability is particularly applicable to electronic protection systems (alarm systems), which due to their specific character of use, should be characterised by the high level of reliability. The devices and electronic units applied in the wide range in those systems, the microprocessor systems in particular, require a new perspective on the reliability and the safety of the...
