- FIG. 2 shows a second exemplary embodiment for a vehicle according to the invention, in which a monitoring device additionally enables a test operation
- FIG. 3 shows a third exemplary embodiment of a vehicle according to the invention, in which a control device connected to an internal direct current network of the vehicle transmits control signals to a monitoring device via a secure connection, the control device, the connection and the monitoring device having a specified safety standard meet, and
- FIG. 4-6 exemplary embodiments for vehicles according to the invention, in each of which an internal direct current network of the vehicle is connected to an external, track-side feed network.
- FIG. 1 shows a vehicle 1, which is preferably an electrically operated or electrically drivable rail vehicle.
- vehicle 1 is connected to a converter 10, which is connected on the input side to a vehicle's own feed network 20 via a connection E10.
- the converter 10 generates a direct voltage U2 at an output A10.
- the output side of the converter 10 is connected to an internal direct current network 30 of the vehicle 1.
- the internal direct current network 30, however, is not directly connected to the converter 10, but via a backup power supply device 40.
- the backup power supply device 40 comprises an energy storage device 41 (e.g. in the form of one or more batteries or capacitors) and a control unit 42 that controls the Converter 10 from the internal direct current network 30 separates.
- the control unit 42 is designed in such a way that it feeds the direct voltage U2 of the converter 10 as an output voltage U3 or mains voltage into the internal direct current network 30 or, alternatively, an auxiliary operating voltage U4 supplied by the energy store 41.
- the control unit 42 is preferably designed such that it feeds the direct voltage U2 of the converter 10 directly into the internal direct current network 30 when the direct voltage U2 is in a predetermined voltage range. If the DC voltage U2 falls below or exceeds specified limits, the control unit 42 will cancel the connection between the converter 10 and the internal DC network 30 and alternatively feed the auxiliary operating voltage U4 of the energy store 41 into the internal DC network 30, so that the further energy supply of the internal Direct current network 30 subsequently takes place through the energy store 41.
- a monitoring device 50 is seen, which is connected to three sensors S1, S2 and S3 via sensor lines not shown for reasons of clarity and from these three sensor signals in the form of control signals Kl, K2 or K3 receives:
- a first control signal Kl which the sensor S1 generates, writes the output from the converter 10 on the output side DC voltage U2 and thus the functioning of the converter 10 and the correct feeding of the converter 10 through the feed network 20, since the converter 10 can only work correctly if it is sufficiently fed.
- a second control signal K2, which the sensor S2 generates, describes the output voltage U3 fed into the internal direct current network 30 by the backup power supply device 40 and thus the functioning of the backup power supply device 40 including the components 41 and 42 contained therein.
- the monitoring device 50 has a computing device 51 and a memory 52.
- a control module KM is stored in the memory 52 which, when executed by the computing device 51, enables or ensures a control operation of the monitoring device 50, which preferably proceeds as follows:
- the monitoring device 50 or its control module KM determines that the first control signal K1 (U2) is within a tolerance range specified for the first control signal Kl and the second control signal K2 (U3) is outside a tolerance range specified for the second control signal K2 is, then it / it generates an error signal Fl indicating an error in the control unit 42 of the replacement power supply device 40 as the status signal Z.
- the monitoring device 50 or its control module KM determines that the third control signal K3 lies outside a tolerance range that is necessary for sufficient charging state of the energy store is characteristic, it / it generates, as the state signal Z, an error signal F2 indicating an error in the energy store 41.
- the monitoring device 50 or the control module KM determines that the first control signal K1 (U2) is outside the tolerance range specified for the first control signal Kl, it generates an error in the converter 10 or an error in the memory as the status signal Z on on the output side error signal F3 indicating senetzes 20.
- FIG. 2 shows a second exemplary embodiment for a vehicle 1 which is equipped with a converter 10, a vehicle's own supply network 20, an internal direct current network 30 and a backup power supply device 40.
- the last-mentioned components correspond to the corresponding components 10 to 40, as they have already been explained in connection with FIG.
- an additional test module TM is stored in the memory 52 of the monitoring device 50, which, when executed by the computing device 51, enables the monitoring device 50 to run test.
- the test module TM or the monitoring device 50 switches off the input-side feed of the backup power supply device 40, that is to say the DC voltage U2 applied to the backup power supply device.
- the DC voltage U2 is switched off by a switch S which is arranged between the input E10 of the converter 10 and the vehicle's own supply network 20.
- the supply of the converter 10 can be stopped, so that the converter 10 can no longer feed DC voltage U2 into the backup power supply device 40 (immediately or at least after internal stored electrical charges or magnetic fields have been released).
- the control signal K1 (U2) will indicate that the input-side feed of the backup power supply device 40 is missing; the control signal K2 (U3) confirms the further supply of the internal direct current network 30, which is now carried out by the energy storage device 41 of the backup power supply device 40.
- the test module TM will observe the time course of the control signals K2 and K3.
- the replacement power supply device 40 will be able to maintain the supply of the internal direct current network 30 for a predetermined minimum period of time, so that the control signals K2 and K3 will continue to indicate proper auxiliary operation of the replacement power supply device 40 for this minimum time period.
- the test module TM can generate a positive test signal P + as a status signal.
- the backup power supply device 40 If the backup power supply device 40, in particular its energy storage device 41, is faulty or not sufficiently charged, the output voltage U3 of the backup power supply device 40 or the line voltage of the internal direct current network 30 will drop before the specified minimum period of time has elapsed; this will be determined by the test module TM of the monitoring device 50. In this case, it will generate an error signal F4 as the status signal, which indicates an incorrect behavior of the replacement power supply device 40, for example due to a deterioration in the charging capacity of the energy store 41 due to aging.
- FIG. 3 shows a third exemplary embodiment for a vehicle 1 in which the components 10, 20, 30 and 40 already described in connection with FIGS. 1 to 2 are present.

- the monitoring device 50 is therefore not directly connected to the sensors S1, S2 and S3, but is only indirectly connected to them via the control device 60.
- the control device 60, the connecting link 70 and the monitoring device 50 are preferably designed such that they meet a predetermined safety standard, preferably at least SAS1 or SIL1.
- FIG. 4 shows an exemplary embodiment for a vehicle 1 in which the converter 10 is not connected to a vehicle's own supply network, but to a route-side supply network 21 external to the vehicle, for example via a pantograph 80.
- the converter 10 and the replacement power supply device 40 serve in the embodiment according to FIG. 4 to feed the DC voltage U1 output by the feed network 21 on the output side in a converted form into the internal DC network 30, as was explained in connection with FIG.
- the above statements apply, including with a view to the operation of the monitoring device 50, accordingly.
- FIG. 5 shows an exemplary embodiment for a vehicle 1 in which the converter 10, as shown in FIG. 4, is connected to a feed network 21 outside the vehicle.
- the electrical arrangement formed from the converter 10, the internal direct current network 30 and the monitoring device 50 corresponds to the electrical arrangement as explained in connection with FIG.
- FIG. 6 shows a variant of the embodiment according to FIG. 5, in which - as explained in connection with FIG. 3 - a control device 60 and a connecting link 70 enable a secure transmission of control signals K1, K2 and K3 to the monitoring device 50; in this regard, reference is made to the above statements in connection with FIG. 3, which apply accordingly here.
