Abstract
According to one aspect of the invention, the circuit logic of an existing relay interlocking system is mapped onto a functionally equivalent circuit of electronic components. Semiconductor components that are functionally identical to the components of the relay circuit are thus preferably used. The circuit logic is created, for example, by transforming an interlocking table or track diagram into a logic circuit by means of an automatic compiler according to predefined rules.
Claims18
A method for building an electronic signal box as a replacement for an existing signal box, wherein the switching logic in the existing signal box is mapped by means of transformation onto a functionally equivalent circuit of electronic semiconductor parts, and the outputs of said circuit are connected to at least some of the existing components to be actuated.
The method as claimed in one of the preceding claims, wherein the outputs of said circuit are connected to the components to be actuated via component-specific input and/or output units without integrated logic or with integrated logic.
The method as claimed in one of the preceding claims, wherein the signal box to be replaced is a relay signal box.
A method, particularly as claimed in one of the preceding claims, for building an electronic signal box as a replacement for a relay signal box, wherein an interlocking plan (V) or a track plan (S) for the relay signal box is transformed into a logic circuit by means of a translator by applying predefined unambiguous rules (T).
The method as claimed in one of the preceding claims, wherein the circuit has a logic unit (L) and a plurality of input and/or output units (IOk), wherein the logic circuit is connected to the input and/or output units in a star shape.
The method as claimed in one of the preceding claims, characterized in that the circuit has two redundant logic units which both execute the same logic function and output the results, respectively, wherein preferably, if the results do not match, a safe state is entered and/or an alarm is triggered.
A signal box, particularly built in accordance with a method as claimed in one of the preceding claims, comprising an electronic logic unit and a plurality of input and/or output units for actuating components such as points, signals, barriers and the like, characterized in that the logic unit is at least to some extent in the form of a programmed semiconductor logic chip.
