Description

Ein Fernsteuer- und Programmiersystem dieser Art für Minen und andere Sperren ist bekannt (System RABAS der Firma Rohde & Schwarz, Datenblatt PD 756.9045.11 vom Juni 1990). Die Steuerbefehle werden über die Funkstrecke bei der Fernsteuerung entweder unmittelbar als codierte Befehle zur Mine übertragen oder gegebenenfalls auch als codierte Speicheradressen, unter welchen die jeweiligen Steuerbefehle im Programmspeicher des Fernbediengerätes und der Mine abgespeichert sind. Es ist auch schon bekannt, sowohl im Fernbediengerät als auch in der Mine einen zusätzlichen Codewortspeicher vorzusehen und bei der Programmierung über einen Zufallsgenerator die Speicheradressen, unter welchen die jeweiligen Steuerbefehle im Programmspeicher abgespeichert sind, als Codewörter zu verschlüsseln und nur diese verschlüsselten Codewörter, die für einen Nichtberechtigten nicht lesbar sind, vom Fernbediengerät zur Mine zu übertragen (DE-PS 40 27 150). Selbst wenn die übertragenen Speicheradressen codiert sind oder nur die durch einen Zufallsgenerator erzeugten Codewörter übertragen werden, besteht die Gefahr, daß der Gegner die vom Funksender ausgestrahlten codierten Adressen oder Codewörter empfängt und seinerseits diese Signale wiederholt aussendet und so unbefugt und unkontrolliert auf die ausgelegten Minen einwirkt. A remote control and programming system of this type for Mines and other barriers are known (RABAS system from Rohde & Schwarz, data sheet PD 756.9045.11 from June 1990). The control commands are over the Radio link in the remote control either immediately transmitted as coded commands to the mine or, if necessary also as coded memory addresses, among which the respective control commands in the program memory of the Remote control device and the mine are stored. It is also already known, both in the remote control device as well as an additional code word memory in the mine to be provided and when programming via a random generator the memory addresses under which the respective control commands are stored in the program memory are to be encrypted as code words and only these encrypted code words for an unauthorized person are not readable, from the remote control device Mine to transfer (DE-PS 40 27 150). Even if the transmitted memory addresses are encoded or only the code words generated by a random generator transferred, there is a risk that the opponent the coded addresses broadcast by the radio transmitter or code words and in turn receives these signals repeatedly emits and so unauthorized and uncontrolled acts on the mines laid out.

Zur verschlüsselten Informationsübertragung zwischen mobilen Sende-Empfangsstationen ist es an sich schon bekannt, sowohl sende- als auch empfangsseitig eine Uhr vorzusehen und bei der Erzeugung der Codierparameter, in Abhängigkeit von denen in einem Pseudonoise (PN)-Generator die eigentliche Codiervorschrift zum Codieren der zu verschlüssenden Information erzeugt wird, in Abhängigkeit von der Momentanzeit zu ändern (Europäische Patentanmeldung 0 050 268). Dabei werden die von einem Schlüsselgeber erzeugten binären Codierparameter mit den binären Ausgangssignalen der Zeituhr fortwährend zu neuen Codierparametern (Schlüssel) verknüpft und gleichzeitig der PN-Generator auf seine Anfangsposition zurückgestellt. Dadurch kann eine Verschlüsselung mit einer relativ kurzen PN-Folgeperiode durchgeführt werden. Bei diesem bekannten System ist außerdem schon vorgesehen, sende- und empfangsseitig jeweils ein Frequenzadressenregister vorzusehen und in Abhängigkeit von der Ablaufsteuerung vor Beginn eines für Rufzwecke vorgesehenen Zeitschlitzes oder eines Sende- bzw. Empfangsinformationsblockes im Sender und im Empfänger jeweils eine neue Übertragungsfrequenz einzustellen (Frequenzsprungverfahren). Selbst bei kombinierter Anwendung dieser bekannten Verschlüsselung der zu übertragenden Information und des Frequenzsprungverfahrens wäre dieses bekannte System für die Fernsteuerung von Minen nicht sicher genug, da durch wiederholtes Aufnehmen der Sendungen bei Kenntnis des Algorithmus aufgrund der wiederholten Rückstellung des PN-Gernerators die Codierparameter von einem Nichtberechtigten herausgefunden werden können und dann wieder eine Fremdbeeinflussung des Fernsteuersystems möglich ist. For encrypted information transfer between mobile transceiver stations are in themselves known, both on the transmitting and receiving side To provide clock and in the generation of the coding parameters, depending on those in a pseudonoise (PN) generator the actual coding regulation for coding the information to be encrypted is generated in Change depending on the current time (European Patent application 0 050 268). The one Key encoders generated binary coding parameters with the binary output signals of the time clock continuously linked to new coding parameters (keys) and at the same time the PN generator to its initial position deferred. This can result in encryption with a relatively short PN follow-up period will. In this known system is also already provided, one on the transmitting and one on the receiving side Provide frequency address register and depending from the sequencer before the start of a call provided time slot or a send or Receive information block in the transmitter and in the receiver to set a new transmission frequency (Frequency hopping method). Even when combined Application of this known encryption to transmitting information and frequency hopping would be this known system for remote control of mines not safe enough because of repeated Record the programs with knowledge of the algorithm due to the repeated reset of the PN generator generator the coding parameters found out by an unauthorized person can become and then another interference of the remote control system is possible.

Entsprechendes gilt für eine bekannte elektronische Schließeinrichtung für Kraftfahrzeuge (Europäische Patentanmeldung 0 215 291), bei der sowohl im Schlüssel (Sender) als auch im Schloß (Empfänger) jeweils wieder synchrone Zeitsteuereinrichtungen vorgesehen sind, wobei zur Verschlüsselung der vom Schlüssel zum Schloß zu übertragenden Kennziffer eine Codiervorschrift benutzt wird, die in Abhängigkeit von den Zeitsteuereinrichtungen zeitabhängig unterschiedlich erzeugt wird. Auch das Prinzip dieser bekannten Schließeinrichtung wäre für ein Fernsteuersystem für Minen nicht geeignet, da die Übertragung der verschlüsseiten Steuerbefehle immer bei der gleichen Sendefrequenz erfolgt und auch damit ein Nichtberechtigter die Möglichkeit hat, durch längere Beobachtung der codierten Befehle deren Codierung zu erkennen.The same applies to a known electronic Locking device for motor vehicles (European Patent application 0 215 291), in which both in the key (Transmitter) as well as in the castle (receiver) again synchronous time control devices are provided, being used to encrypt the key to the lock a coding rule to be transmitted is used depending on the timing devices is generated differently depending on the time. The principle of this known locking device would not be suitable for a remote control system for mines, since the transmission of the encrypted control commands always takes place at the same transmission frequency and also so that an unauthorized person has the opportunity to longer observation of the coded commands their coding to recognize.

Es ist Aufgabe der Erfindung, ein Fernsteuersystem für Minen und andere Sperren zu schaffen, das gegen Fremdbeeinflussung absolut sicher ist. It is an object of the invention to provide a remote control system for mines and other barriers to create that against Interference is absolutely certain.

Diese Aufgabe wird ausgehend von einem Fernsteuersystem für Minen laut Oberbegriff des Hauptanspruches durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This task is based on a remote control system for mines according to the preamble of the main claim its characteristic features solved. Beneficial Further training results from the subclaims.

Beim erfindungsgemäßen Fernsteuersystem wird unabhängig von der Art der Übertragung der Steuerbefehle durch die sowohl in der Mine als auch im Fernbedienungsgerät eingebauten synchron arbeitenden Zeitsteuereinrichtungen die Möglichkeit geschaffen, verschiedene Parameter der Befehlsübertragung zeitabhängig zu verändern, so daß der Gegner nur sich mit der Zeit ändernde Signale empfängt, die nicht mehr zeitkonstant sind und daher von ihm nicht ausgewertet und auch nicht zur Störung des Fernsteuersystems wiedererzeugt werden können. Damit ist ein solches Fernsteuersystem gegen Fremdbeeinflussung völlig sicher. Für die zeitabhängige Beeinflussung der Steuerbefehlsübertragung gibt es dabei verschiedene Möglichkeiten. Eine erste Möglichkeit ist, daß gesteuert durch die synchron arbeitenden Zeitsteuereinrichtungen im Fernbediengerät und in der Mine der Code zeitabhängig geändert wird, mit dem die Befehle bzw. die Speicheradressen oder die entsprechenden Codewörter übertragen werden. Eine andere Möglichkeit besteht darin, die Steuerbefehle über den Funksender wiederholt auf verschiedenen Frequenzen zu senden (frequency hopping) oder zu verschiedenen nicht vorhersehbaren Zeiten zu senden (time hopping). Die zeitsynchron arbeitenden Zeitsteuereinrichtungen sind im einfachsten Fall zeitsynchron arbeitende Uhren, die auf geeignete Weise synchronisiert sind, beispielsweise über das sogenannte GPS-System (Global Positioning System). Es können aber auch elektronische Zeitsteuereinrichtungen verwendet werden, beispielsweise in Form von elektronischen Zählern, die jeweils durch einen über den Funksender ausgestrahlten Steuerbefehl gleichzeitig im Programmiergerät und in der Mine synchron gestartet werden und damit dann als synchron arbeitende Zeitsteuereinrichtungen wirken.In the remote control system according to the invention, 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. There are various options for influencing the control command transmission as a function of time. 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. Another possibility is to send the control commands repeatedly via the radio transmitter on different frequencies (frequency hopping) or to send them at different unpredictable times (time hopping). The synchronously working time control devices are in the simplest case synchronously operating clocks which are synchronized in a suitable manner, for example via the so-called GPS (Global Positioning S ystem). However, 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.

Die Erfindung wird im folgenden anhand einer schematischen Zeichnung an einem Ausführungsbeispiel näher erläutert.The invention is based on a schematic Drawing explained in more detail using an exemplary embodiment.

Die Fig. zeigt ein erfindungsgemäßes Fernsteuer- und Programmiersystem für Minen M, das ein Fernbediengerät aufweist, das im gezeigten Ausführungsbeispiel aus einem Programmierteil P und einem Fernbedienteil F besteht. Durch die Aufteilung des Fernbediengeräts in ein Programmierteil und in ein Fernbedienteil können einerseits an einer Stelle Minen programmiert und verlegt werden und an einer anderen Stelle über das Fernbedienteil die Minen gesteuert werden. Die beiden Geräteteile P und F können natürlich auch in einem einzigen Gerät zusammengefaßt werden.The Fig. Shows an inventive remote control and Programming system for mines M, which is a remote control device has, in the embodiment shown from a Programming part P and a remote control part F exists. By dividing the remote control unit into a programming part and in a remote control unit on the one hand mines can be programmed and installed in one place and elsewhere on the remote control Mines are controlled. The two parts of the device P and F can of course also be combined in a single device will.

Der Programmierteil P besteht aus einem Mikroprozessor 1 mit zugehörigem Arbeitsspeicher 2, einer Uhr 3 und einer Bedientaste 6. Im Programmierteil P ist ferner noch ein Zufallsgenerator vorgesehen, der fortlaufend zufällig erzeugte Codierparameter liefert, die beim Codieren der Steuerbefehle benutzt werden. Am Programmierteil P ist ferner eine Vorrichtung zur Aufnahme eines gesonderten Codespeichers S vorgesehen, der beispielsweise als übliche Magnetkarte ausgebildet und in einen entsprechenden Schlitz des Programmierteils P einsetzbar ist. Über einen induktiven Koppler 5 des Programmierteils P können auf kürzestem Wege Signale zu einem entsprechenden induktiven Koppler 27 in der Mine M übertragen werden.The programming part P consists of a microprocessor 1 with associated memory 2, a clock 3 and an operating button 6. In the programming part P is also another random generator is provided, which is continuous provides randomly generated coding parameters that the Coding of the control commands can be used. On the programming part P is also a device for receiving a separate code memory S is provided, for example designed as a conventional magnetic card and in a corresponding Slot of the programming part P can be used is. Via an inductive coupler 5 of the programming part P can use the shortest possible route to a corresponding signal inductive coupler 27 are transmitted in the mine M.

Der Fernbedienteil F besteht wieder aus einem Mikroprozessor 10 mit zugehörigem Arbeitsspeicher 11, einer mit dem Mikroprozessor 10 verbundenen Uhr 13, einer Codierlogik 14 mit Codespeicher 15 und einer mit dem Mikroprozessor 10 zusammenwirkenden Bedientastatur 12 sowie eine Aufnahmevorrichtung für den Codespeicher S. In einem Programmspeicher 16 sind unter vorbestimmten Adressen A, B, C, D verschiedene Steuerbefehle für die Mine abgespeichert, unter der Adresse A beispielsweise der Befehl "Mine aktivieren", unter der Adresse B der Befehl "Mine deaktivieren" usw. Über einen Funksender 17 können die Steuerbefehle zu einem Funkempfänger 22 in der Mine M übertragen werden.The remote control part F again consists of a microprocessor 10 with associated working memory 11, one with the clock 13 connected to the microprocessor 10, a coding logic 14 with code memory 15 and one with the microprocessor 10 interacting control keyboard 12 as well a recording device for the code memory S. In one Program memories 16 are at predetermined addresses A, B, C, D stored various control commands for the mine, for example, the command at address A. "Activate mine", the command "Mine deactivate "etc. Via a radio transmitter 17, the Control commands to a radio receiver 22 in the mine M be transmitted.

In der Mine M ist ein dem Programmspeicher 16 entsprechender Programmspeicher 26 angeordnet, in welchem wiederum unter den gleichen Adressen A, B, C ... die gleichen Steuerbefehle wie im Speicher 16 abgespeichert sind. Außerdem ist noch eine Decodierlogik 24 mit zugehörigem Codespeicher 25 und ein Mikroprozessor 20 mit Arbeitsspeicher 21 vorgesehen, dem wieder eine Uhr 23 zugeordnet ist und über den außerdem die Zünd- und Sicherungseinrichtungen 28 der Mine gesteuert sind.In the mine M is a program memory 16 corresponding Program memory 26 arranged, in turn at the same addresses A, B, C ... the same Control commands as stored in memory 16. There is also a decoding logic 24 with associated Code memory 25 and a microprocessor 20 with memory 21 provided, which is assigned a clock 23 again is and through which also the ignition and safety devices 28 of the mine are controlled.

Mit einem System dieser Art kann eine zu verlegende Mine M wie folgt programmiert werden:A system of this type can be used to lay a mine M can be programmed as follows:

Die Speicherkarte S wird in die Aufnahmevorrichtung des Programmierteils P einsteckt. Dann wird die Programmiertaste 6 betätigt. Unter Berücksichtigung der momentanen Uhrzeit der Uhr 3 werden dann die durch den Zufallsgenerator erzeugten Codierparameter zeitabhängig erfaßt und diese somit auch die jeweilige Uhrzeit enthaltenden Codierparameter werden einerseits auf die Speicherkarte S aufgespeichert und gleichzeitig über die induktive Verbindung 5-27 (der Koppler 27 der Mine M wird zu diesem Zweck möglichst nahe an den Koppler 5 des Programmierteils P gebracht) zur Mine M übertragen und dort im Codespeicher 25 der Decodierlogik 24 abgespeichert. Damit enthält der Codespeicher S des Programmierteils P und auch der Codespeicher 25 der Mine M jeweils die zufällig erzeugten Codierparameter, die zur Erzeugung einer zeitabhängigen Codier- bzw. Decodiervorschrift nötig sind.The memory card S is in the cradle of the Programming part P inserted. Then the programming button 6 operated. Taking into account the current Time of clock 3 will then be the one generated by the random number generator generated coding parameters recorded time-dependent and these also contain the respective time Coding parameters are stored on the one hand on the memory card S stored and at the same time via the inductive Connection 5-27 (the coupler 27 of the mine M becomes this Purpose as close as possible to the coupler 5 of the programming part P brought) transferred to mine M and there in the code memory 25 of the decoding logic 24 is stored. So that contains the code memory S of the programming part P and also the Code memory 25 of mine M each of the randomly generated Coding parameters used to generate a time-dependent Coding or decoding regulations are necessary.

Zur Fernsteuerung der Mine M über den Fernbedienteil F wird die Speicherkarte S aus dem Programmierteil P herausgenommen und in den Fernbedienteil F eingesteckt, dort werden die abgespeicherten Codierparameter ausgelesen und in den Codespeicher 15 der Codierlogik 14 eingelesen. Soll nun beispielsweise in einem beliebigen Zeitpunkt t1 die Mine M durch Fernsteuerung aktiviert werden, so betätigt der Benutzer die Taste A, über den Mikroprozessor 10 wird unter Berücksichtigung der Zeit t1 der Uhr 13 und der durch die Codierparameter im Codespeicher 15 zu dieser Zeit t1 vorbestimmten Codiervorschrift die Adresse A des Programmierspeichers 16 entsprechend codiert und über den Sender 17 zum Empfänger 22 der Mine M übertragen, hier werden nunmehr durch den Mikroprozessor 20 aus dem Codespeicher 25 die gleichen Codierparameter wie aus dem Codespeicher 15 ausgelesen und nach der so für die Zeit t1 der Uhr 23 bestimmten gleichen Decodiervorschrift in der Decodierlogik 24 aus der übertragenen Information die Adresse A decodiert, die dann über den Mikroprozessor 20 aus dem Programmspeicher 26 den zugehörigen Steuerbefehl "Mine aktivieren" ausliest und der Zünd- und Sicherungseinrichtung 28 zuführt, durch die dann die Mine entsprechend aktiviert wird. Wird zu einem späteren Zeitpunkt t2 beispielsweise die Deaktivierung der Mine M gewünscht und durch den Benutzer die Taste B betätigt, so wird über den Mikroprozessor 10 unter Berücksichtigung der Uhrzeit t2 ein anderer Code als zum Zeitpunkt t1 zufällig erzeugt, über die synchron mit der Uhr 13 arbeitende Uhr 23 kann jedoch wiederum in der Mine M die gleiche Decodiervorschrift erzeugt werden wie sie zum Codieren des Befehls im Fernbedienteil F im Zeitpunkt t2 benutzt wurde. Durch diese beliebige zufällige zeitabhängige Änderung der jeweiligen Codiervorschrift kann ein Gegner nicht erkennen, welche codierten Befehle zur Minensteuerung übertragen werden, da sich diese laufend ändern, er hat also keine Möglichkeit, unbefugt in das Fernsteuersystem für Minen einzugreifen.For remote control of the mine M via the remote control part F, 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. If, for example, 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 feeds it to the ignition and safety device 28, which then activates the mine accordingly. If, for example, deactivation of the mine M is desired at a later point in time t 2 and the user presses the B key, a different code is generated by the microprocessor 10, taking into account the time t 2, than at the point in time t 1 , via which synchronously with However, the clock 13 working clock 23 can in turn be generated in the mine M the same decoding rule as was used to code the command in the remote control unit F at the time t 2 . This random, time-dependent change in the respective coding rule means that an opponent cannot recognize which coded commands are being transmitted to the mine control system, since these are constantly changing, so he has no possibility of tampering with the remote control system for mines.

Neben einer zeitabhängigen Änderung der Codiervorschrift ist es auch möglich, jeweils gesteuert über die synchron arbeitenden Uhren 13, 23 die Sendefrequenz des Funksenders 17 und die entsprechende Empfangsfrequenz des Funkempfängers 22 nach einem durch den Mikroprozessor 10 bzw. 20 vorgegebenen Programm sprunghaft zu ändern oder zu verschiedenen für den Gegner nicht vorhersehbaren Zeiten zu senden und zu empfangen. In addition to a time-dependent change in the coding regulation it is also possible to be controlled via the synchron working clocks 13, 23 the transmission frequency of the radio transmitter 17 and the corresponding reception frequency of the radio receiver 22 after one by the microprocessor 10 or 20 to change or change the specified program different times not predictable for the opponent to send and receive.

In dem gezeigten Ausführungsbeispiel ist sowohl im Programmierteil P als auch im Fernbedienungsteil F eine Uhr 3 bzw. 13 vorgesehen, dies ist bei abgesetzten Geräten nötig. Wenn die beiden Geräteteile P und F in einem Gerät zusammengefaßt sind ist natürlich nur eine einzige Uhr und auch nur ein einziger Mikroprozessor erforderlich. Eine andere Möglichkeit besteht darin, unmittelbar auf der Speicherkarte S eine entsprechende elektronische Zeitsteuereinrichtung in Form eines Mikrochips 4 anzubringen, dadurch werden getrennte Uhren 3 und 13 überflüssig, da über die Zeitsteuereinrichtung 4 bei eingesteckter Speicherkarte S auch die jeweilige momentane Zeit ausgelesen und beim Programmieren bzw. bei der Fernsteuerung entsprechend berücksichtigt werden kann.In the embodiment shown, both in Programming part P as well as in the remote control part F a Clock 3 or 13 provided, this is with remote devices necessary. If the two device parts P and F in one device of course, only one watch is summarized and even a single microprocessor is required. Another option is to go straight to it the memory card S a corresponding electronic To install the timing device in the form of a microchip 4, This eliminates the need for separate clocks 3 and 13, since via the timing device 4 when plugged in Memory card S also the current one Time read and when programming or at Remote control can be taken into account accordingly.

Die Übertragung der Codierparameter vom Programmteil P zur Mine M bei der Programmierung erfolgt im dem gezeigten Ausführungsbeispiel vorzugsweise über die induktive Koppelvorrichtung 5, 27, die ein unbefugtes Abhören der Programmiervorschrift verhindert. Zu dieser Übertragung der Codierparameter wäre jedoch auch unmittelbar die für die Fernsteuerung vorgesehene Funkstrecke 17, 22 geeignet.The transmission of the coding parameters from the program part P to mine M during programming is done in the shown Embodiment preferably on the inductive Coupling device 5, 27, the unauthorized interception of the Programming rule prevented. About this transfer however, the coding parameter would also be immediate radio link 17, 22 provided for remote control suitable.

Die Uhren im Fernbediengerät und in der Mine müssen mit möglichst geringem Gangunterschied arbeiten, dazu können diese Uhren in gewissen Zeitintervallen, beispielsweise über Funk, nachsynchronisiert werden, je nach Güte der Uhren ist dies beispielsweise monatlich ausreichend.The clocks in the remote control unit and in the mine must be with work as little as possible, can these clocks at certain time intervals, for example can be re-synchronized via radio, depending on the quality of the For example, this is sufficient for watches every month.

Eine Möglichkeit zur Energieeinsparung in der Mine besteht darin, über die synchronen Uhren 13, 23 die stromverbrauchenden elektronischen Bauteile in der Mine M, insbesondere den Empfänger 22, den größten Teil der Zeit ausgeschaltet zu lassen und nur in vorbestimmten, im Mikroprozessor 10 bzw. 20 abgespeicherten Zeitintervallen, einzuschalten, also nur dann, wenn eine Übertragung notwendig ist. Auf diese Weise wird eine wesentlich längere Liegezeit für die Minen bei gleicher Leistungsfähigkeit der Empfangsanlage erreicht bzw. bei gleicher Liegezeit der Mine eine wesentliche Verbesserung der Empfangsanlage.There is a way to save energy in the mine therein, the power consuming ones via the synchronous clocks 13, 23 electronic components in the mine M, in particular the receiver 22, most of the time to be turned off and only in predetermined, in Microprocessor 10 or 20 stored time intervals, switch on, so only when a transmission is necessary is. This way a much longer one Lying time for the mines with the same performance the reception system reached or with the same lay time the mine a significant improvement in the reception system.

Um zu vermeiden, daß unautorisiertes Personal eine Programmierung bzw. Fernsteuerung ausführt, kann die Funktionsfähigkeit des Systems von dem Vergleich eines eingegebenen mit einem auf der herausnehmbaren Speicherkarte S gespeicherten Autorisierungscode abhängig gemacht werden.To avoid unauthorized personnel from programming or remote control, the functionality of the system by comparing an entered one with one on the removable memory card S stored authorization code made dependent will.
