Embodiment Construction

[0019] figure 1 A system S for controlling a central control station according to a first embodiment is shown. Here, the original hardware device H is shown, which is replicated several times, i.e. multiple replicas R1a, R1b, R1c, R2a, R2b, R2c are generated for redundancy, which, in the absence of failure, generate Same control signals as original hardware device H. System S comprises a plurality of replicas R1a, R1b, R1c, R2a, R2b, R2c and associated voter structures 1 . Multiple replicas R1a, R1b, R1c, R2a, R2b, R2c generate control signals for voting through the voter structure 1 . As hardware device H or as replicas R1a, R1b, R1c, R2a, R2b, R2c, for example electrical circuits, logic circuits, processors, computers, control devices etc. are conceivable, wherein the invention is not limited to these examples. Signals for controlling central control stations can be used, for example, in order to switch switches; to activate track blocking; or, for example, to ensure that...

Abstract

A system (S) is provided, in particular for controlling central control stations in railway traffic, having at least a plurality of redundant copies (R1a, R1b, R1c, R2a, R2b) for generating redundant control signals , R2c). There is also provided a voter structure (1) comprising a plurality of majority voters (M1, M2), wherein each majority voter (M1, M2) has a plurality of redundant replicas (R1a, R1b, R1c, The output terminals of R2a, R2b, R2c) are connected to the input terminals and the corresponding output terminals. According to the invention, the voter structure (1) and the multiple redundant replicas (R1a, R1b, R1c, R2a, R2b, R2c) are constructed separately from each other in terms of hardware technology, and the multiple majority voters (M1, M2 ) is connected to the input of the discriminator voter (D), wherein the output of the discriminator voter (D) provides a control signal especially for controlling the centralized control station. It outputs a control signal only when the inputs of the discriminator voter (D) do not contradict each other.

Description

technical field [0001] The invention relates to a system, in particular for controlling central control stations in railway traffic. Background technique [0002] In railway traffic, the control signals used to control centralized control stations must meet certain safety requirements. In this case, this usually involves a distributed system which generates the corresponding output or control signals. In this case, the signal-generating hardware device is duplicated several times in order to increase security, which is referred to as so-called duplication. The output of this so-called replica is directed to a central voter (Voter). Such a voter is a decision maker that produces the "correct" output data from a given amount of redundant input data. Usually, a majority voter is used for this, which generates the output signal by a majority decision. An output signal, a so-called voting signal, can be provided to the user. This voting signal is trustworthy. However, in th...
