Definitions

  • the invention relates to an arrangement for transmission, radiation and reception of high-frequency signals, consisting of a system connected to a transmitting and receiving device comprising at least one suitable for guiding electromagnetic waves high-frequency component and a parallel to the same, first signal cable is constructed, in which the signal cable is connected in each case at intervals arranged at coupling points with the high-frequency component in a manner suitable for guiding the high-frequency signals manner ( Proceedings of the 1st International Conference on Tunnel Control and Communication, 28th to 30th November 1994, pages 181 to 192 ).
  • NBS tunnel radio for customer services.
  • Technical Alternatives and System Description J. Leinweber, Signal + Thr. 6, June 1990 "describes two completely different technical solutions for the construction of a tunnel radio system: a slot planing system suspended from the tunnel walls and a 40 GHz radio relay network with digital transmission.
  • the information is transmitted in each case with low loss via the two signal cables.
  • Information coming from the transmitter is fed into the AHF cable at the adjustable power coupling points, so that RF signals of sufficiently high level can always be received along the same.
  • the Range of transmission can be significantly increased without the use of repeaters, even if in the course of the transmission line a larger number of coupling points between the AHF cable and the two signal cables is present.
  • the functionality of the transmission path is safer. Even if one of the signal cables is damaged or destroyed, the functionality of the system is maintained because the AHF cable continues to be connected to the transmitter and receiver via the other signal cable. This increased security is achieved in a very simple manner.
  • Each of the two signal cables is namely continuously connected to every other coupling point. The equipment costs and the structure of the coupling points therefore remain unchanged. Only a second signal cable is needed.
  • Each of the two signal cables supplies, in cooperation with its associated coupling points, sections of the AHF cable, in both directions of transmission.
  • both signal cables are functional - fed from two different coupling points signals in each leg of the AHF cable.
  • signals received by the AHF cable also run into two coupling points delimiting the respective part of the same.
  • AHF cable is subdivided in a manner known per se into sections which are arranged one behind the other in the longitudinal direction, a coupling point is assigned to each section.
  • the subdivision of the AHF cable can be made, for example, to safely avoid interference.
  • a signal cable or the associated part of the transmitting and receiving device must then be ensured that the sections are automatically interconnected. This can be done according to the DE 195 03 744 A1
  • equipped with a switch components are used, which are controllable by a pilot signal of the transmitting and receiving device.
  • an AHF cable 1 and a parallel thereto extending signal system 2 to a transmitting and receiving device 3 are connected, which has a transmitter S and a receiver E. and can be equipped with an antenna 4.
  • the signal system 2 is according to Fig. 2 from two signal cables 5 and 6, via which RF signals are transmitted with low loss.
  • the two fiber optic cables 5 and 6 are connected to coupling points K1 to Kn with the AHF cable 1, in a manner suitable for guiding RF signals.
  • "n" is an integer, even number.
  • electro / optical converters are available, which are known per se and therefore not shown. In this manner and RF signals can be transmitted from the transmitting and receiving device 3 to the antenna of a vehicle moving along the AHF cable 1 or even a portable radio and vice versa.
  • the AHF cable 1 and the two fiber optic cables 5 and 6 are expedient spatially separated from each other.
  • the two fiber optic cables 5 and 6 have a large spatial distance from each other. They may advantageously be attached to the two opposite walls of the tunnel T.
  • fiber optic cables 5 and 6 can also be mounted in different tunnels. It is then prevented with great certainty that both fiber optic cables 5 and 6 can be damaged at the same time. The functionality of the arrangement is thereby ensured even if one of the fiber optic cables 5 or 6 is damaged.
  • the RF signals are routed from the other fiber optic cable 5 or 6.
  • both fiber optic cables 5 and 6 are connected to the coupling points K1 to Kn with the AHF cable 1, and accordingly Fig. 2 alternately.
  • the fiber-optic cable 5 is connected to the odd-numbered coupling points K1, K3, K5 .... Kn ⁇ 1 to the AHF cable 1.
  • the even-numbered coupling points K2, K4, K6 Vietnamese Kn are provided.
  • the count starts accordingly Fig. 2 at the transmitting and receiving device 3, and without interruption.
  • the structure of the coupling points K1 to Kn remains unchanged compared to an arrangement with only one fiber optic cable. For the increased security of the arrangement so only the second fiber optic cable is needed.
  • the fiber optic cable 5 or its associated part of the transmitting and receiving device 3 fails, the functionality of the arrangement is maintained by the optical fiber cable 6.
  • the coming of the transmitting and receiving device 3 RF signals are now fed only via the even coupling points K2 to Kn in the AHF cable 1. This is sufficient with proper sizing but to ensure a sufficiently high reception level along the AHF cable 1. It also remains ensured that RF signals fed into the AHF cable 1 reach the transmitting and receiving device 3.
  • the AHF cable 1 according to Fig. 3 be divided into sections A, which are arranged one behind the other in the longitudinal direction.
  • each section A is one of the coupling points K1 to Kn attached, preferably symmetrically.
  • switching elements 7 are arranged, through which the sections A can optionally be interconnected. This is required if one of the fiber optic cables 5 or 6 fails.
  • Such a structure of the arrangement is based in principle from the DE 195 03 744 A1 out.
  • the pilot signal no longer arrives in case of failure of one of the optical fiber cables 5 or 6 or of the associated part of the transmitting and receiving device 3 in a receiver 8 or 9 of the switching element 7, this is detected by the associated evaluation unit 10. From the corresponding sections A of the AHF cable 1 then no RF signal could be received and it could also be forwarded no RF signal. By the evaluation unit 10, the switches 11 are then immediately closed, so that in each case a conductive connection between the two connected to the switching element 7 Sections of the AHF cable 1 is made. The arrangement is then fully functional as shown above.
