Definitions
- the invention relates to a system, in particular for controlling signal boxes in rail traffic.
- control signals for the control of signal boxes must meet certain safety requirements. It is typically dealing with distributed systems, each generating outputs or control signals. While signal-generating Hardwareeinrich ⁇ obligations are replicated multiple times to increase security, which are so-called replicants. The expenses of these so-called
- Replicants are directed to central voters.
- a voter is a decider that generates the "correct" output data from a given number of redundant input data, often using majors that produce an output signal by a majority vote.
- the output signals called voted signals, are provided to the consumer.
- Such voted signals are trustworthy, but with central voters the weak point is the voter per se, because if this voter fails, there is no transmission of voted signals to the consumers
- the object is to provide an alternative system insbeson ⁇ particular for the control of signal boxes available, which has a low risk of failure, as well as high availability.
- a system in particular for controlling signal boxes in rail traffic, which Ches at least a plurality of redundant replicants for generating redundant control signals.
- a voter structure is provided that includes a plurality of majors, each of which has mismatch inputs connected to the outputs of the plurality of redundant ones
- Replicants are connected, and each having an output.
- Voter Arbitrary replicants from each other and connected to the outputs of the plurality of Maj orticiansvoter to the inputs of Diskriminatorvoters, wherein the output of Diskriminatorvoters provides a control signal insbesonde ⁇ re available for the control of signal boxes.
- the discriminator voter does not output a control signal if its inputs contradict each other.
- the invention has the advantage that the majority of the replicants and the voter structure are in distinct failure units due to the hardware separation, which simplifies the localization of malfunctions or failures. Furthermore, the object regions are thereby separated voneinan ⁇ the.
- commercially üb ⁇ Liche computing hardware can be used by this division and it does not have to be reset gripped with integrated Vote purities ⁇ to specific hardware. Furthermore, can be advantageous by the
- Discriminator voter be issued only a control signal, if its inputs are not contradictory, which also the deviation of an upstream Majoryvoters can festge ⁇ feststell ⁇ can be. Since in the pre-stage the majors voter control signals already voted by majority voting are transferred to the discriminator voter, an additional
- the discriminator voter has a less complex and thus more failure resistant hardware than a majory voter, so that the failure probability of the system according to the invention is reduced.
- the discriminator voter preferably acts as a through switch if only one input signal is present. As a result, a failure of one or more majors voters be compensated, so that at the output of the discriminator still a
- Voted control signal is output.
- the United ⁇ availability of the system is increased because the failure of a
- An error message is preferably output if the discriminator voter receives no input signal from a majity voter.
- a plurality of downstream discriminator voters may be used, with the outputs of the plurality of majory voters associated with each input
- Discriminator are connected, wherein at each output of the respective Diskriminatorvoters a control signal, in particular ⁇ special for controlling interlockings, is provided. This provides redundancy in terms of
- Discriminator voter achieved. Should a discriminator voter fail, a control signal is still available at the output of the other discriminator voters. In addition, the respective control signals can be compared with each other. Thus, the system can tolerate a failure of a discriminator voter.
- a plurality of replicants may be spatially separated from a plurality of replicants, and / or the plurality of downstream majory voters and / or the plurality of discriminator voters may be spatially separated. In practice one often deals with spatially distributed systems. For example, a plurality of
- Replicants are located in different locations, but generate the same control signal per location. Even the majors voters or the discriminator voters can be separated. Now fall one of these "places" from, for example, be ⁇ sondere events such as power failures, natural disasters, etc., so still a gevotetes control signal can be provided at one or at different locations available. This is a local redundancy is generated because of the failure of a In addition, a failure of a discriminator voter or associated connections will have less of an impact on the system as they are located on the receiver or consumer failure unit.
- An error message can be output if not all input signals to a majory voter are equal. As a result, an error localization can be achieved, which can lead to a check or replacement of a replicant. Furthermore, deviating inputs of a majory voter can be reliably blocked.
- the entire system can be blocked if the
- Discriminator voter receives no input signal from a majory voter or if the inputs of the
- the downstream discriminator voter or the plurality of downstream discriminator voters can form a stand-alone configurable device.
- the downstream discriminator voter or the plurality of downstream discriminator voters is integrated within an evaluation unit. This are out ⁇ evaluation unit and Diskriminatorvoter in the same unit failure.
- Figure 2 System for controlling interlockings according to a second embodiment

- FIG. 1 shows a system S for controlling interlockings according to a first embodiment.
- an original hardware device is illustrated H that is replicated multiple times, that is, a plurality of replicants Ria, RLB, Rlc, R2a, R2b, R2c gene ⁇ riert redundancy creation, the same control signal erzeu ⁇ gene in the trouble-free case as the original hardware device H.
- the system S environmentally summarizes the plurality of replicants Ria, RLB, Rlc, R2a, R2b, R2c and an associated Voter Cook 1 generates the plurality of replicants Ria, RLB, Rlc, R2a, R2b, R2c Steuersigna ⁇ le, which are voted on the Voter réelle 1.
- the signal for the control of interlockings can be used to convert a switch, to activate a track lock or, for example, a Schal ⁇ th a traffic light from red to green to ensure, with many other appropriate taxes in rail transport into consideration.

- M ority voters M1, M2 connected i. the outputs of the plurality of replicants Ria, Rlb, Rlc, R2a, R2b, R2c are located at the inputs of the plurality of majors Vm, M2.
- the outputs of the replicants Ria, Rlb, Rlc are purely exemplary at the inputs of Ml and the outputs of the replicants R2a, R2b, R2c at the inputs of M2.
- the majors Ml, M2 form a majority vote for their output signal on the basis of their incoming signals, ie if a majority of the inputs have the same signal, this is output. If purely by way of example of Ria and Rlb a "high level” and of Rlc a "low level” is received, then there is a high level at the output of Ml. In the normal case, that is the interference-free case, the same control signals are present at the inputs, which are then output at the output by the master-level Ml. In the case of a deviation of an input signal, for example the replicant Rlc, this can additionally lead to an error message. Furthermore, deviating inputs of a majors voter can be reliably blocked.

- the outputs of the plurality of maj orticiansvoter Ml, M2 are inventively connected to the inputs of a discriminator Voters D, whose output signal represents the control signal for Steue ⁇ tion of interlockings. Only if the inputs of the Discriminator Voters D contradict each other, is of the
- Discriminator voter D produces no output signal. This can advantageously be the departure of an upstream
- Voter structure 1 and replicants Ria, Rlb, Rlc, R2a, R2b, R2c then advantageously form different precipitation units. This can advantageously be a targeted localization of a failure source. In addition, no longer needs to spe ⁇ cial hardware be drawn with integrated Vote units, but it may be the commercially usual computer hard ⁇ ware used.
- the discriminator voter D acts like a
- the entire system S can be blocked if the discriminator voter D of one
- the downstream discriminator voter D can form a standalone configurable device. However, the downstream discriminator voter D can also be integrated within an evaluation unit, thus forming a failure unit with the evaluation unit.
