Definitions

  • a remote control and programming system of this type for mines and other barriers is known (system RABAS from Rohde & Schwarz, data sheet PD 756.9045.11 from June 1990).
  • the control commands are transmitted via the radio link in the remote control either directly to the mine as coded commands or, if appropriate, also as coded memory addresses under which the respective control commands are stored in the program memory of the remote control device and the mine.
  • the remote control system regardless of the type of transmission of the control commands by the synchronously operating time control devices built into both the mine and in the remote control device, the possibility is created to change various parameters of the command transmission as a function of time, so that the opponent only receives signals which change over time which are no longer constant in time and therefore cannot be evaluated by him and cannot be regenerated to disrupt the remote control system.
  • Such a remote control system is completely safe against external interference.
  • a first possibility is that, controlled by the synchronously operating time control devices in the remote control device and in the mine, the code is changed in a time-dependent manner with which the commands or the memory addresses or the corresponding code words are transmitted.
  • time-controlled time control devices are time-synchronized clocks that are synchronized in a suitable manner, for example via the so-called GPS system (Global Positioning System).
  • GPS system Global Positioning System
  • electronic time control devices can also be used, for example in the form of electronic counters, each of which is started synchronously in the programming device and in the mine by a control command emitted via the radio transmitter and thus then act as synchronously operating time control devices.
  • the FIGURE shows a remote control and programming system for mines M according to the invention, which has a remote control device, which in the exemplary embodiment shown consists of a programming part P and a remote control part F.
  • a remote control device which in the exemplary embodiment shown consists of a programming part P and a remote control part F.
  • the programming part P consists of a microprocessor 1 with associated working memory 2, a clock 3 and an operating key 6.
  • a random generator which continuously provides coding parameters which are generated randomly and which are used in coding the control commands.
  • a device for receiving a separate code memory S is also provided, which is designed, for example, as a conventional magnetic card and can be inserted into a corresponding slot in the programming part P. Signals can be transmitted in the shortest possible way to a corresponding inductive coupler 27 in the mine M via an inductive coupler 5 of the programming part P.
  • the remote control part F again consists of a microprocessor 10 with associated working memory 11, a clock 13 connected to the microprocessor 10, a coding logic 14 with a code memory 15 and an operating keyboard 12 interacting with the microprocessor 10, and a recording device for the code memory S.
  • a program memory 16 Various control commands for the mine are stored at predetermined addresses A, B, C, D, at address A, for example, the command "mine activated ren ", the address” deactivate mine "etc. at address B.
  • the control commands can be transmitted to a radio receiver 22 in the mine M via a radio transmitter 17.
  • a program memory 26 corresponding to the program memory 16 is arranged in the mine M, in which in turn the same control commands as in the memory 16 are stored under the same addresses A, B, C.
  • a decoding logic 24 with associated code memory 25 and a microprocessor 20 with working memory 21 is provided, to which a clock 23 is again assigned and via which the ignition and safety devices 28 of the mine are also controlled.
  • a mine M to be installed can be programmed as follows: the memory card S is inserted into the receiving device of the programming part P. Then the programming button 6 is pressed. Taking into account the current time of the clock 3, the coding parameters generated by the random generator are then recorded as a function of time, and these coding parameters containing the respective time of day are stored on the one hand on the memory card S and at the same time via the inductive connection 5-27 (the coupler 27 of the mine M For this purpose, it is brought as close as possible to the coupler 5 of the programming part P) and transferred to the mine M and stored there in the code memory 25 of the decoding logic 24.
  • the code memory S of the programming part P and also the code memory 25 of the mine M each contain the randomly generated coding parameters which are necessary for generating a time-dependent coding or decoding rule.
  • the memory card S is removed from the programming part P and inserted into the remote control part F, where the stored coding parameters are read out and read into the code memory 15 of the coding logic 14.
  • the mine M is to be activated by remote control at any time t 1
  • the user presses the button A via the microprocessor 10 taking into account the time t 1 of the clock 13 and the coding parameters in the code memory 15 at this time t 1 predetermined coding specification
  • the address A of the programming memory 16 is correspondingly coded and transmitted via the transmitter 17 to the receiver 22 of the mine M, here the same coding parameters are now read out from the code memory 25 by the microprocessor 20 as from the code memory 15 and after that for the time t 1 of the clock 23 determines the same decoding rule in the decoding logic 24 from the transmitted information decodes the address A, which then reads the associated control command "activate mine" from the program memory 26 via the microprocessor 20 and supplies it to the ignition and safety device
  • a clock 3 or 13 is provided both in the programming part P and in the remote control part F; this is necessary in the case of remote devices. If the two device parts P and F are combined in one device, of course, only a single clock and also only a single microprocessor are required. Another possibility is to mount a corresponding electronic time control device in the form of a microchip 4 directly on the memory card S, as a result of which separate clocks 3 and 13 become superfluous, since the current time can also be read out via the time control device 4 when the memory card S is inserted and can be read out during programming or can be taken into account accordingly with the remote control.
  • the coding parameters are transferred from program part P to mine M during programming, preferably via inductive coupling device 5, 27, which prevents unauthorized eavesdropping on the programming instruction.
  • the radio link 17, 22 provided for remote control would also be suitable for this transmission of the coding parameters.
  • the clocks in the remote control unit and in the mine must have the smallest possible gear difference work, these clocks can be re-synchronized at certain time intervals, for example via radio, depending on the quality of the clocks, this is sufficient, for example, monthly.
  • One way of saving energy in the mine is to leave the power-consuming electronic components in the mine M, in particular the receiver 22, switched off for the majority of the time via the synchronous clocks 13, 23 and only in predetermined ones, in the microprocessor 10 or 20 stored time intervals, so only when a transmission is necessary. In this way, a significantly longer lay time for the mines is achieved with the same performance of the receiving system or, with the same lay time of the mine, a significant improvement in the receiving system.
  • the functionality of the system can be made dependent on the comparison of an authorization code entered with an authorization code stored on the removable memory card S.
