BALISEN CONNECTION FOR THE SELECTION OF A ETCS OF TELEGRAM TO A RELAY SIGNAL TOWER

[0001] The available invention concerns a Balisen connection for the selection of a ETCS telegram to a relay signal tower in accordance with the generic term of the patent claim 1, like e.g. from the contribution “ETCS migration in that s Switzerland with Balisenlesegerät " of T. Mueller and H. existing building, SIGNAL + WIRE (94), expenditure 1 +2/2002 admits is. [0002] System the ERTMS - resuming information see - can be introduced only gradually. So also older relay signal towers are to be turned on to a Balise and an associated light signal. An overview of the existing train control system systems like also the replacement replacing by ETCS the writing gives to ETR number 11/2000 under the title of “train control system systems of European courses” p. 725 to 733 of Professor Dr. Jörn Pachl. The technical 'o specification of the ETCS is contained in the appropriate documents the UNIVERSITY VICTORY. [0003] In figure 1 the arrangement in principle is represented to system by Balisengruppen L0, L1, L2 of the ETGS/Eurobalise before a Hauptsignal 3, arranged at points of distance. With the reference symbol R the direction of travel of a course is indicated. A Balisengruppe at the points of distance L0, L1 or L2 contains at least two Balisen. A Balisengruppe can cover up to eight one behind the other arranged Balisen. Balisen can as always same '5 telegrams sending Festdatenbalisen F or as controllable Transparentbalisen T implemented its. transparency balisen T transfer the contents of, that is a signal term, a telegram coming of from an adapter LEU to a vehicle. The arrangement at least in pairs of Balisen in Balisengruppen is necessary, in order to recognize with passage by means of a firm identification in a telegram the direction of travel R of the over-driving course. The group in accordance with L0 the Fig. 1 covers a Transparentbalise T and a Festdatenbalise F. in a further distance (not L2 per a further group with two Balisen each is arranged 20 full-scale drawn) of the Hauptsignal 3 at two further points of distance L1 and. The group of L1 is formed by two Festdatenbalisen F and the group of L3 of a Festdatenbalise F and a Transparentbaalise T. [0004] Relay signal towers 4 are turned on in accordance with past practice in the way represented in figure 2 to a Transparentbalise T. In addition is for the adapter LEU 2 an additional power supply from a set off 25 relay area over a line 6 necessarily. The connection transparency balise T to the adapter of a LEU (reference symbol 2 in Fig. 3) requires on side of the Transparentbalise T as in Fig. 4 shown: Telegram memory 9, telegram selection 11 30 - contact inquiry of the connection of relay 7. In the following is usually only of Balise T in place of Transparentbalise T the speech. The principle in accordance with the figure 3 contains: The signal term (which lamp shines and which not) is supplied with an electrical contact or a current switch of the Balise T by way of a line 12. The logic of the Balise T changes and/or selects the correct telegram part, tel2,…, which in a non volatile telegram memory 9 one programmed. This Telegram part, tel2,…, is strengthened in the signal achievement and called arrived at a transmission loop 18, this also Uplink. [0005] Those managing described connection in accordance with the figures 2 to 4 has the disadvantage that does not admit is, how the telegram selection can be accomplished signal-technically surely and simply. The requirement for the correct selection of a ETCS telegram part. .tel2. .ist in the course safety engineering with an error rate within the range 40 given from 10-6/h to 10-9/h, SIL 1 - 4, EN 50129. [0006] The available invention is the basis the task to indicate a circuit for the selection of a ETCS telegram to a relay signal tower with which the demanded error rates can be proven. [0007] This task solved according to invention by the connection indicated in the requirement 1. [0008] Favourable execution forms of the available invention are indicated in the dependant requirements. 45[0009] by the connection of railway signal according to invention, whereafter A) the ETCS telegrams per asignalcoming of which can be selected from a telegram-specific signal sourceis overlaid; b) a multiplexer connected by an address bus with the relay logic is, whereby the relay logicsets 50due to agiven signal term on the address bus an address, with that the multiplexer with one Signal overlaid ETCS telegram selected; C) the multiplexer with a transmission stage for the transmission of the ETCS telegrams overlaid with a signal is connected; D) the transmission stage (15) with an analog comparator is connected to coming ofsignals, in that by the amplifier produced overlaid 55 telegram concerning the overlaid signal by telegram-specific second signal sourcesis also compared and e) the analog comparator is connected with the relay logic, so that the result of the comparisonis restorableto the relay logic; EP 1,759,953 B1 a Balisen connection is created, which ensures a continuous examination of the telegram lesson over a closed chain permitted and with a “single-channel” structure to immediate error revealing and thus the necessary safety requirements. Favourable execution forms of the available invention are specified in the dependant requirements. s A remark example of the invention is more near described in the following on the basis the design. Show: Figure 1 Arrangement of Balisengruppen before a Hauptsignal, arranged at points of distance; Figure 2 Connection of a Transparentbalise to relay signal towers in accordance with past practice; Figure 3 More detailed representation of the connection in accordance with figure 2, whereby the LEU is omitted; 'o Figure 4 Detailed block diagram of a Transparentbalise; Figure 5 Remark example of the available invention with a Transparentbalise by telegram lesson of telegrams provided with an overlaid signal; Figure 6 Level representation of the telegrams provided with overlaid signals. 15 the connection in accordance with the figures 2 to 4, well-known from the state of the art, one does not show here again, but an execution form of the available invention is described on the basis the figure 5. Those are here subsummiert managing indicated explanations for the state of the art. Previous still another remark on the term “signal”. This term is doubly occupied in this writing: 20 i) “signal” as driving term and/or as means for the announcement of a driving term; ii) Electrical “signal” of a signal source. From the respective context is to be derived however easily, in which allocation the term “signal” is used. [0010] The figure 5 shows as “admitted” of component a connection of relay 7 and/or a relay logic 7 for those 25 signal term conversion. The relay logic 7 is connected by an address bus adrs with a Mulitplexer 13. The relay logic 7 puts an address adrs, with which Mulitplexer the addresses selects adrs assigned pre-programmed telegrams Teil', Tel2',… due to a given signal term to the address bus adrs. The telegrams part, Tel2', etc., are overlaid with one signal each U1, U2, etc. by second signal sources Q1, Q2, etc. for the telegram concerned part, Tel2 and/or for the driving term concerned. The additional signal source Q1, Q2, possesses so favourably different signal characteristics than the telegram. A signal-term-specific DC offset, that is particularly favourable is DC voltage. The additional signal is transmitted as well by the whole chain up to the exit of the transmission stage 15 and decoded there in an additional logic. [0011] A T-member 20 carries the uncoupling out of the overlaid check signal of to send the telegram part, of Tel2. In the figure 5 this is circuit-moderately symbolized with a condenser Gl. This separation can as active 35 or as passive uncoupling out-arranged its. The check signal covers the overlaid of signal U1, U2, etc. additional signal sources of the Q1, Q2 and the information signal, which are the telegrams part, Tel2, etc. the overlaid signal can as dynamic signal be implemented, e.g. from a source of sine coming of. The condenser Gl symbolizes a band-pass filter and/or a band suppressor in this case. The RG-network in an educated manner from resisted R3 and the condenser the G2 works as a time window for the examination of the function of the comparator 14. are represented to 40[ooi 2] in the figure 5 for three telegrams part, Tel 3 and Tel 2 the overlay. The tension of the signal sources Q1, Q3 and Q2, which can be added in addition, is represented in the lower part. The amplitudes are provided with a DG offset. Entire deflection (point points value) can remain quite also with the offset equivalent in addition, differently, i.e. to be asymmetrically out-arranged. [0013] The feedback to the connection of relay 14 takes place via a comparison of the exit of the signal to 45 exit of the transmission stage 15 with the reference signal sources Ovl, Ov2 in an analog comparator 17 planned per reference signal. The result of the comparison of all analog comparators is coded in a unit 16 and put on the address bus adrc. The address put on the address bus adrc corresponds to the preselected telegraphic cable address with the correct selection of the Telegrames adrs. For the safe and genuine transmission to the comparator 14 however the address can be reciprocally negated adrs. The comparator 14 examines the agreement of the addresses adrs 50 and adrc. This agreement is finally passed on at the logic and/or connection of relay 7. [0014] The logic 7 and/or connection of relay 7 can be out-arranged as memory programmed circuit SPS. [0015] we already managing partly implemented, can than signal which can be overlaid in place of a DG-Offsets also an AG tension be used. In principle all signals which deeper frequency portions than the Telegramsignal are suitable contain for an overlay. The relationship should for instance 1:20 = fAC: fTe| its. With a frequency 55 of the telegram of fTe| =564 kHz are 0 < fAC < 30 kHz well possible overlaid signals in the frequency range. Thereby sinusoidal signals are preferential. For fAC = 0 those is managing in the remark example of the invention very in detail revealed DG-overlay enclosed.
