Definitions

  • the invention relates to a method for transmitting remote control signals according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 3.
  • Methods for remote control of mobile objects in which command telegrams are transmitted between the transmitter stations and the mobile objects using a single carrier frequency, are widely known.
  • the individual transmitter stations can send to the addressed receiving stations cyclically one after the other, the individual transmitter stations automatically synchronizing with the time slot of the specified multiplex transmission frame, and those transmitter stations whose transmission times have not yet been reached are excluded from transmission; see. DE 23 54 067.
  • a random generator can also be provided in each transmitter station, which determines the timing of the transmission of the command telegrams for the relevant transmitter station; see. DE 25 51 013.
  • the ranges can be optimized by optimizing the structure and circuit design of the radio remote controls and the transmitting and receiving antennas are enlarged, but do not prevent that undesired radio interruptions occur in the transmission system over longer ranges, which, due to the requirements of the existing safety regulations, result in the locomotives to be remotely switched off.
  • the experimental use of so-called active / passive antenna reflectors instead of the usual rod antennas led to corresponding experiences.
  • additional amplifier stations of the type of relay stations are to be set up for remote control of locomotives in the field. These amplifier stations are intended to receive the signals of the portable radio remote control transmitters - frequency F1 - and additionally transmit them on another frequency - frequency F2.
  • two separate high-frequency receivers must be provided for each receiver on the locomotives to be remote-controlled, so that the downstream receiver evaluation circuit can receive the signals from the portable radio remote control transmitter - F1 - and the signals - F2 - from the repeater station at the same time.
  • the invention is therefore based on the object of increasing the range between the transmitters and receivers of such radio remote control devices by simple technical measures using a single transmission frequency.
  • one or more so-called receive-transmit (repeater) stations are provided distributed in the area within which the locomotives to be remote-controlled can be moved.
  • a repeater station receives the signals from the radio remote control transmitters and transmits them again at the same frequency with a time delay.
  • the portable radio remote control transmitters and the repeater station belong to a common time division multiplex system, so that the transmissions of the radio remote control transmitters cannot be disturbed and the individual command telegrams are transmitted at different times according to a predetermined scheme.
  • the repeater station which automatically classifies itself in this time-division multiplex system and adjusts its transmission time for the repeated transmission of a received command telegram so that it is sent out in a time gap within this time-division multiplex system.
  • FIG. 1 shows an overview of the components of a radio remote control system for the remote control of locomotives with a receive-transmit (repeater) station MEREP.
  • Pending control commands in the form of command telegrams can be radioed from a number of portable transmitter stations S1 to Sn to locomotive receivers L1 to Ln, which are there received and converted into control signals for controlling the locomotive.
  • these signals are received by the repeater station MEREP, which sends these signals again to the locomotive receivers L1 to Ln within a time gap.
  • the mobile receiving stations are thus embodied here by the radio receivers arranged on the locomotives to be controlled remotely.
  • FIG. 2 shows the receive-transmit station according to the invention, designated by reference number 3, also referred to as the repeater station MEREP, which has a receiver 4 for evaluating the command telegrams received via an antenna 7 and transmitted by one of the transmitter stations.
  • a delay circuit 6 and an evaluation circuit 9, to which the LF output signal of the high-frequency receiver 4 is present, are connected to the receiver.
  • the LF output signal is time-delayed via these switching elements and then transmitted again via an HF transmitter 5, the delay time of the delay circuit 6 corresponding at least to the transmission time for the command telegram to be transmitted in the relevant transmitter station.
  • the command telegram pending at the output of the HF receiver 4 is simultaneously fed to the delay element 6 and the evaluation circuit 9 and evaluated there. If it is determined in the evaluation circuit 9 that the received command telegram has an identifier S to be described, the repeater station recognizes that the received command telegram should be sent again. Via the evaluation circuit 9, the RF transmitter 5 is then released in the for the renewed Sending this command telegram provided, determined by the delay element 6 time gap in the time schedule of the time division multiplex system.
  • the additional identifier S can be generated in the transmitter stations, for example, in such a way that a switch S-MEREP is located in the keypad of the command telegram input device (not shown here) is provided, which is to be operated by the operator when this detects range problems.
  • the additional identifier can also be generated by certain command combinations. In such a case, the S-MEREP switch is then omitted.
  • FIG. 3 shows a further embodiment of the MEREP repeater station.
  • this includes a transmission timing control 10 which controls a command message memory 8.
  • the command telegram pending at the output of the HF receiver 4 is stored in the memory 8 and at the same time fed to the transmission timing controller 10. There, the transmission time of the MEREP transmitter 5 is determined and the transmission is initiated by simultaneously giving the transmission release to the HF transmitter 5 and the command for reading out the stored command telegram to the memory 8.
  • the transmission timing control selects the transmission timing so that the time division multiplex system to which the transmitters S1 to Sn belong is not disturbed.
  • FIGS. 1 and 2 The working of the device according to FIGS. 1 and 2 is explained below with reference to the pulse diagram according to FIG. 4, which is based on an asynchronous radio remote control method according to DE 23 51 013 mentioned at the beginning. The same applies to other radio remote control methods, such as. B. the synchronous according to DE 23 54 067 also mentioned at the beginning.
  • Such a time-division multiplex system has a random generator in each transmitter station, which determines the time sequence for the transmission of the command telegrams for the respective transmitter station.
  • FIG. 4 shows the pulse diagram over the time course of the rectangular oscillations of pseudo-random generators PZRG from two transmitter stations and the transmission times of the command telegrams S1 and S2. The transmissions t s take place there only if two logical ONE appear after a 0-1 transition of the pseudo-random rectangular sequence PZRG that occurred immediately before. A further transmission is blocked for the time t BLOCKING.
  • the command telegram received from the transmitter station S2 is now evaluated. Due to the existing additional identifier S, which was decoded from the command telegram, the delay circuit 6 is triggered, which embodies a fixed delay time. After the delay time of the delay circuit 6 the command telegram is made available to the transmitter 5 for transmission and sent as soon as the evaluation circuit 9 has given the release.
  • the additional programs are identified in FIG. 4 by the reference symbol 11 and take place immediately after the programs t sj and t sj + 1 , ie the delay time of the delay circuit 6 is only slightly longer than the transmission time of S2.
  • the two pulse transmission diagrams of the transmitters S1 and S2 in FIG. 5 correspond to those of FIG. 4.
  • a pulse transmission diagram of the receive-transmit station MEREP 1 is shown, the MEREP 1 station also being in the area of influence of the two transmitters S1 and S2 of the example according to Figure 4 should work.
  • the transmission-time control of the reception-transmission station works according to the same time-division multiplex basic scheme that the two transmitters obey, that is to say the transmission-time control 10 in principle also contains a pseudo-random generator PZRGM 2 with the function as previously explained for the purpose of Figure 4 described.
  • the associated pulse-rectangular curve PZRGM 2 is shown in FIG. 5.
  • the command telegrams t sj and t sj + 1 are evaluated in the transmission timing controller 10 and released for retransmission via the transmitter 5 of the receiving-transmitting station MEREP (t sM and t sM + 1 ), since in the example shown the command telegram has the additional identifier S has.
  • the pulse transmission diagrams t sM and t sM + 1 are denoted in FIG. 5 by the reference symbol 11.
  • the transmission times control 10 thus determines the transmission times t sM and t sM + 1 on the basis of the pseudo-random generator according to the pulse diagram PZRGM 2. After reception of t sj and t sj + 1 , a retransmission takes place if immediately after the 0-1- Transition of the pulse diagram PZRGM 2 two logical ones are present, as already described at the beginning.
  • the transmission time of the repetition by the receiving-transmitting station is determined by the time division multiplex system of the transmission timing control and not by a delay circuit with a fixed time delay as in the embodiment according to FIG. 2 and can therefore be used Adjust time-division multiplex scheme automatically.
  • the transmission timing control 10 can also be carried out according to principles other than the time division basic scheme of the transmitters S1 to Sn, such as statistical methods, mathematical methods, monitoring of the radio channel, etc. Other methods are particularly useful when the time division basic diagram of the Radio remote control transmitter in the sphere of influence of the receiving-transmitting station MEREP is not known.
