Abstract:

In this paper the analyses of the interlocking (control) table of the railway station signalling system is carried out to allow the microprocessor control . Control table represents the synthesis of the safety criteria and traffic demands that shall be implemented into the operation logic of the station interlocking system . The solutions, which present a control table as a set of logic functions of Boolean type, thus, transform this complex task in the form that enables very simple programming, are given.
