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.
Claims19
A method for setting up an electronic signal box as a replacement for an existing signal box, comprising the steps of:
- providing the existing signal box, the existing signal box being connected to components to be actuated for the rail transportation and to actuate said components, the existing signal box having a switching logic,
- providing the switching logic of the existing signal box in an electronically readable form,
- mapping, by means of a transformation, the switching logic onto a logic function that corresponds to the electronic representation of a logic circuit, that is functionally equivalent with the switching logic,
- using the representation to physically configure a configurable logic circuit being a circuit of electronic semiconductor parts,
- whereby the switching logic of the existing signal box is physically mapped onto the functionally equivalent configurable logic circuit by means of the transformation, and
- connecting outputs of said configurable logic circuit to at least some of the existing components to be actuated;
- and
- whereby the configurable logic circuit actuates the components to be actuated without the use of a processor.
An electronic signal box as a replacement for an existing signal box for a rail transportation,
- wherein the existing signal box is connected to components to be actuated for the rail transportation before the existing signal box is replaced by the electronic signal box and includes a switching logic physically mapped onto hardware,
- the electronic signal box comprising an electronic logic unit comprising a configurable logic circuit and a plurality of input and/or output units for actuating the components, the input and/or output units connected to at least some of the components,
- wherein the configurable logic circuit is a circuit of electronic semiconductor parts functionally equivalent to the switching logic of the existing signal box, and
- whereby the configurable logic circuit actuates the components to be actuated without the use of a processor.
