Abstract

An infrared remote control for automotive soil compacting equipment such as rollers, vibration plates and so forth is proposed which ensures that the equipment cannot be set in motion by remote control as long as the operator with the transmitting unit 10 is so close to the soil compacting equipment BV that a starting caused by unwanted remote control or initiated in the wrong direction of movement of the equipment could be dangerous to him. This is achieved according to the invention by the fact that, apart from the infrared control beam intended for the functional control of the equipment, an infrared close-range beam having much less intensity compared with the control beam is transmitted so that it can only be received with sufficient intensity by the receiving unit 11 in the close vicinity of the transmitter 10. When this close-area beam is received, the formation or output of electrical signals which otherwise, caused by the control beam, effect the travel of the soil compacting equipment is suppressed in the receiving unit. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 und auf eine Infrarot-Steuereinrichtung zum Durchführen dieses Verfahrens.The invention relates to a method according to the preamble of claim 1 and to an infrared control device for performing this method.

Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 sind bekannt. Sie ermöglichen es, ein Bodenverdichtungsgerät aus der Entfernung hinsichtlich vieler gewünschter Funktionen wie Vorwärtsfahrt, Rückwärtsfahrt, Arbeiten auf der Stelle, Ein- und Ausschalten des Antriebsmotors u. dgl. zu steuern. Die Fernsteuerung als solche hat den Vorteil, daß sich der Bedienungsmann nicht in der unmittelbaren Umgebung des Bodenverdichtungsgerätes, in der er meist durch eine erhebliche Lärm- und Staubentwicklung gefährdet ist, aufhalten muß.Methods according to the preamble of claim 1 are known. They make it possible to operate a soil compactor from a distance with regard to many desired functions such as driving forward, driving backwards, working on the spot, switching the drive motor on and off and the like. To control. The remote control as such has the advantage that the operator does not have to be in the immediate vicinity of the soil compacting device, in which he is usually endangered by considerable noise and dust.

Bei den bekannten Fernsteuerungen ist es leicht möglich, das Bodenverdichtungsgerät ungewollt in Bewegung zu versetzen oder ungewollt zunächst in eine falsche Richtung laufen oder anlaufen zu lassen. Dies ist besonders gefährlich, wenn sich der Bedienungsmann hierbei in unmittelbarer Nähe des Bodenverdichtungsgerätes befindet, weil dann die Gefahr besteht, daß er von diesem überfahren wird.In the known remote controls, it is easily possible to set the soil compacting device in motion unintentionally or to let it run or start unintentionally in the wrong direction. This is particularly dangerous if the operator is in the immediate vicinity of the soil compacting device because there is then a risk that he will be run over by it.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 zu schaffen, das eine ungewollte Bedienung hinsichtlich verschiedener Funktionen, die für einen sich in der Nähe des Gerätes aufhaltenden Bedienungsmann gefährlich sind, mit Sicherheit ausschließt, so lange sich der Bedienungsmann nicht in einer ausreichenden Entfernung von dem Gerät befindet.The invention has for its object to provide a method according to the preamble of claim 1, that excludes unintentional operation with regard to various functions that are dangerous for an operator in the vicinity of the device, as long as the operator is not at a sufficient distance from the device.

Die vorgenannte Aufgabe wird durch im Kennzeichnungsteil des Patentanspruchs 1 genannten Merkmale gelöst.The above object is achieved by the features mentioned in the characterizing part of patent claim 1.

Die gemäß der Erfindung mit wesentlich geringerer Intensität als die Steuerstrahlung von der Sendeeinheit ausgesendete Nahbereichsstrahlung erreicht die Empfangseinheit am Bodenverdichtungsgerät mit einer für den Empfang ausreichenden Intensität nur dann, wenn sich der Bedienungsmann mit der Sendeeinheit in der Nähe des Geräts befindet. Bei Empfang dieser Nahbereichsstrahlung wird die Bildung oder Ausgabe von Steuersignalen für den Bedienungsmann gefährdende Operationen, die dieser über die Stuerstrahlung veranlassen möchte, in der Empfangseinheit unterbunden, so daß der Bedienungsmann über die Steuerstrahlung keine solchen für ihn gefährlichen Operationen einleiten kann, so lange er sich nicht in einer sicheren Entfernung von dem Gerät befindet.The short-range radiation emitted according to the invention with a much lower intensity than the control radiation from the transmitter unit reaches the receiver unit on the soil compacting device with an intensity sufficient for reception only when the operator with the transmitter unit is in the vicinity of the device. When this short-range radiation is received, the formation or output of control signals for operations which endanger the operator and which he wishes to initiate via the control radiation are prevented in the receiving unit, so that the operator cannot initiate such operations which are dangerous for him as long as he is doing so is not at a safe distance from the device.

Die Unteransprüche 2 und 3 betreffen bevorzugte Ausgestaltungen des Verfahrens gemäß Patentanspruch 1.The sub-claims 2 and 3 relate to preferred embodiments of the method according to claim 1.

Mittels des weiteren Bereichssignals, des Fernbereichssignals, gemäß Patentanspruch 2 wird verhindert, daß das Bodenverdichtungsgerät aus der Reichweite der Fernsteuerung herausläuft und dann nicht mehr kontrollierbar ist, bevor die Intensität der Steuerstrahlung aufgrund einer zu großen Entfernung des Empfangsortes vom Sender so gering geworden ist, daß ein sicherer Empfang nicht mehr gewährleistet ist.By means of the further range signal, the far range signal, according to claim 2, it is prevented that the soil compacting device runs out of the range of the remote control and is then no longer controllable before the intensity of the control radiation has become so low due to the distance of the receiving location from the transmitter being too great that secure reception is no longer guaranteed.

Im Falle der Sperrung der gefährlichen Signale bleiben die übrigen Funktionen des Gerätes über die Steuerstrahlung weiterhin steuerbar, so daß z. B. der Antriebsmotor noch ein- oder abschaltbar ist, nachdem das Gerät aufgrund eines nicht mehr ausreichenden Empfangs des Fernbereichssignals stillgesetzt wurde oder wegen zu geringer Entfernung vom Sender nicht in Gang gesetzt werden kann.If the dangerous signals are blocked, the remaining functions of the device can still be controlled via the control radiation, so that, for. B. the drive motor can still be switched on or off after the device has been stopped due to insufficient reception of the long-range signal or cannot be started because the distance from the transmitter is too short.

Die Unteransprüche 4 und 5 betreffen eine Fernsteuereinrichtung zum Durchführen des erfindungsgemäßen Verfahrens.The dependent claims 4 and 5 relate to a remote control device for performing the method according to the invention.

Die Erfindung wird nachstehend anhand der Zeichnung an einem Ausführungsbeispiel noch näher erläutert:
Die Fig. 1 zeigt in perspektivischer Darstellung schematisch ein Bodenverdichtungsgerät BV, hier eine Bodenverdichtungswalze, sowie durch konzentrische Linienzüge S1, S2 und S3 gegeneinander abgegrenzten Entfernungsbereiche, wobei angenommen ist, daß sich ein Bedienungsmann mit einem Infrarotsender zur Steuerung des Bodenverdichtungsgerätes BV im Zentrum befindet. Der Linienzug S3 umgrenzt um den Bedienungsmann herum einen Nahbereich, in dem für ihn ein sich darin bewegendes, insbesondere ungewollt in Gang gesetztes Bodenverdichtugsgerät gefährlich ist. Zwischen den Linienzügen S3 und S2 befindet sich der normale, für den Bedienungsmann ungefährliche Arbeitsbereich des Bopdenverdichtungsgerätes, und in dem Bereich außerhalb des Linienzuges S1, aber erst ab diesem, kann die Infrarotstrahlung, über die das Bodenverdichtungsgerät BV funktionell gesteuert wird, vom Empfänger an dem Bodenverdichtungsgerät nicht mehr richtig empfangen werden.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment:
Fig. 1 shows a perspective view schematically a soil compacting device BV, here a soil compacting roller, as well as distance ranges delimited from each other by concentric lines S1, S2 and S3, it being assumed that an operator with an infrared transmitter for controlling the soil compacting device BV is in the center. The line train S3 delimits a near area around the operator, in which a soil compacting device which is moving therein, in particular which is started unintentionally, is dangerous for him. Between the lines S3 and S2 is the normal, safe area for the operator of the crop compacting device, and in the area outside the line drawing S1, but only from this, the infrared radiation, via which the soil compacting device BV is functionally controlled, can be transmitted from the receiver to the Soil compactor can no longer be received correctly.

Die Fig. 2 gibt schematisch ein Ausführungsbeispiel einer zum Durchführen des erfindungsgemäßen Verfahrens geeigneten Infrarot-Fernsteuereinrichtung wieder.2 schematically shows an embodiment of an infrared remote control device suitable for carrying out the method according to the invention.

Die Fernsteuereinrichtung gemäß Fig. 2 weist eine Sendeeinheit 10 und eine Empfangseinheit 11 auf.2 has a transmitter unit 10 and a receiver unit 11.

Die Sendeeinheit 10 ist von einem Bedienungsmann bedienbar. Sie weist drei Infrarotstrahlung aussendende Diode D1, D2 und D3 auf, die über ICs S1 , S2 und S3 zeitlich der Reihe nach angesteuert werden. Diese ICs werden mittels eines Ringzählers Z periodisch nacheinander aktiviert und versorgen die zugehörige Diode jeweils mit einem eine vorbestimmte Frequenz aufweisenden Wechselstrom, wobei jedes der ICs diesen Wechselstrom mit einer zugehörigen, sich von den anderen ICs unterscheidenden "Adresse" kodiert, so daß auch das von der zugehörigen Diode D1 ausgesendete Wechsellicht diese Adresse enthält. Die Adressierung besorgt das IC S1 in Verbindung mit einem Kodierschalter C, der es ermöglicht, für eine bestimmte Sendeeinheit 10 eine von mehreren möglichen Addressierungen für das IC S1 auszuwählen, so daß die Möglichkeit besteht, mehrere, in örtlich benachbarten Gebieten arbeitende Sendeeinheiten 10 so einzustellen, daß sie sich gegenseitig nicht in dem Sinne stören können, daß von ihnen auch andere als die zugehörige Empfangseinheit 11 beeinflußbar sind.The transmitter unit 10 can be operated by an operator. It has three diodes D1, D2 and D3 which emit infrared radiation and are controlled in time via ICs S1, S2 and S3. These ICs are periodically activated one after the other by means of a ring counter Z and each supply the associated diode with an alternating current having a predetermined frequency, each of the ICs encoding this alternating current with an associated "address" which differs from the other ICs, so that the of alternating light emitted by the associated diode D1 contains this address. The addressing is provided by the IC S1 in conjunction with a coding switch C, which makes it possible to select one of a number of possible addressings for the IC S1 for a specific transmission unit 10, so that it is possible to set a plurality of transmission units 10 operating in locally adjacent areas that they cannot interfere with each other in the sense that they can also influence other than the associated receiving unit 11.

Demgegenüber ist sind die Addressencodes für die ICs S2 und S3 fest verdrahtet.In contrast, the address codes for the ICs S2 and S3 are hard-wired.

Zusätzlich zu der Addresse sind bei dem IC S1 mehrere unterschiedliche Datencodes zur Übertragung verschiedener Funktionsbefehle an das Bodenverdichtungsgerät BV einkodierbar, unter denen der Bedienungsmann mit einer Schalteinrichtung SE durch Betätigen einer zugehörigen Taste T₁ - Tn jeweils einen auswählen kann. Das einkodierte Datensignal bewirkt in der Empfangseinheit 11 die Bildung eines ihm zugeordneten elektrischen Steuersignals, das eine bestimmte Funktion bei dem Bodenverdichtungsgerät auslöst, auf dem die Empfangseinheit 11 angeordnet ist.In addition to the address, several different data codes for the transmission of various function commands to the soil compacting device BV can be encoded in the IC S1, among which the operator can select one with a switching device SE by pressing an associated key T 1 - T n . The encoded data signal causes in the receiving unit 11 the formation of an electrical control signal assigned to it, which triggers a specific function in the soil compacting device on which the receiving unit 11 is arranged.

Die Empfangsintensität der von den Dioden D1, D2 und D3 emittierten Strahlungen nimmt mit wachsender Entfernung der Empfangseinheit 11 von der Sendeeinheit (10) am Ort der Emfangseinheit 11 ab.The receiving intensity of the radiation emitted by the diodes D1, D2 and D3 decreases with increasing distance of the receiving unit 11 from the transmitting unit (10) at the location of the receiving unit 11.

Die Diode D1 strahlt Infrarotlicht mit einer größeren Intensität aus als die Diode D2, und das von der Diode D2 ausgestrahlte Infrarotlicht hat eine größere Intensität als das von der Diode D3 ausgesendete.The diode D1 emits infrared light with a greater intensity than the diode D2, and the infrared light emitted by the diode D2 has a greater intensity than that emitted by the diode D3.

Die von der Diode D1 ausgesendete Infrarot-Strahlung, die, wie gesagt, außer der ihr zugeordneten Addressenkodierung auch eine Kodierung mit Steuerdaten zur Empfangseinheit 11 überträgt, bildet die Steuerstrahlung für das zu steuernde Bodenverdichtungsgerät BV. Demgegenüber dienen die von den Dioden D2 und D3 ausgesandten Infrarotstrahlungen, die nur eine Addressenkodierung beinhalten, als Strahlungen, die aufgrund der Intensität, mit der sie die Empfangseinheit 11 erreichen, für die Entfernung charakteristisch sind, in der sich die Empfangseinheit 11 von der Sendeeinheit 10 jeweils befindet. Wegen der unterschiedlichen Intensität, mit der diese Strahlungen von der Sendeeinheit 10 ausgesendet werden, ist die Entfernung, bei welcher sie von der Empfangseinheit 11 noch empfangen werden können, verschieden groß. Die von der Diode D3 ausgesendete Strahlung ist von der Empfangseinheit 11 nur in sehr kleiner Entfernung von der Sendeeinheit 10, z. B. bis zu dem Linienzug S3 in Fig. 1, empfangbar. Demgegenüber kann die von der Diode D2 ausgesendete Strahlung bis zu einer wesentlich größeren Entfernung der Empfangseinheit 11 von der Sendeeinheit 10, z. B. bis zu dem Linienzug S2 in Fig.1, von der Empfangseinheit 11 empfangen werden. Die von der Diode D1 ausgesendete Strahlung empfängt die Empfangseinheit 11 bis zu einer noch größeren Entfernung, z. B. bis zum Linienzug S1 in Fig 1.The infrared radiation emitted by the diode D1, which, as said, also transmits a coding with control data to the receiving unit 11 in addition to the address coding assigned to it, forms the control radiation for the soil compacting device BV to be controlled. In contrast, the infrared radiation emitted by the diodes D2 and D3, which only contain an address coding, serve as radiation which, due to the intensity with which they reach the receiving unit 11, are characteristic of the distance at which the receiving unit 11 is separated from the transmitting unit 10 each is located. Because of the different intensity with which these radiations are emitted by the transmitter unit 10, the distance at which they can still be received by the receiver unit 11 is different. The radiation emitted by the diode D3 is from the receiving unit 11 only at a very short distance from the transmitting unit 10, for. B. up to the line S3 in Fig. 1, receivable. In contrast, the radiation emitted by the diode D2 can be up to a substantially greater distance of the receiving unit 11 from the transmitting unit 10, e.g. B. up to the line S2 in Fig.1, received by the receiving unit 11. The radiation emitted by the diode D1 is received by the receiving unit 11 up to an even greater distance, e.g. B. up to the line S1 in Fig. 1st

Solange das von der Diode D3 ausgesendete Infrarotlicht von der Empfangseinheit 11 empfangen wird, werden in der Empfangseinheit 11 bestimmte Befehle, die die von der Diode D1 ausgesendete und von der Empfangseinheit richtig empfangene Steuerstrahlung auslösen möchte, unterdrückt. Das gleiche geschieht, wenn die von der Diode D2 ausgesendete Strahlung von der Empfangseinheit 11 nicht mehr empfangen wird. Es werden dabei auf jeden Fall mindestens immer diejenigen Steuerbefehle unterdrückt, die für die Fortbewegung des Bodenverdichtungsgerätes maßgeblich sind, so daß bei zu geringer Entfernung der Empfangseinheit 11 und damit des Bodenverdichtungsgerätes von der Sendeeinheit 10 und bei zu großer Entfernung zwischen diesen das Bodenverdichtungsgerät nicht in Gang gesetzt werden kann bzw. stehenbleibt. In jedem Falle aber ist die Steuerstrahlung von der Empfangseinheit 11 empfangbar, so daß damit die restlichen Befehle durchführbar bleiben. Die von den Dioden D2 und D3 ausgesendeten Strahlungen dienen also der Kennzeichnung eines Nahbereichs (Diode D₃) und eines Fernbereichs (Diode D₂), und die von ihnen ausgesendeten Infrarotstrahlungen stellen somit eine Nahbereichsstrahlung bzw. Fernbereichsstrahlung dar, deren Empfangsintensität für die Durchführbarkeit bestimmter Steuerbefehle maßgeblich ist.As long as the infrared light emitted by the diode D3 is received by the receiving unit 11, certain commands which would like to trigger the control radiation emitted by the diode D1 and correctly received by the receiving unit are suppressed in the receiving unit 11. The same happens when the radiation emitted by the diode D2 is no longer received by the receiving unit 11. In any case, at least those control commands that are decisive for the movement of the soil compacting device are suppressed, so that if the receiving unit 11 and thus the soil compacting device are too close to the transmitting unit 10 and the distance between them is too great, the soil compacting device will not start can be set or stops. In any case, however, the control radiation can be received by the receiving unit 11, so that the remaining commands remain executable. The radiation emitted by the diodes D2 and D3 thus serve to identify a short-range (diode D₃) and a long range (diode D₂), and the infrared radiation they emit thus represents short-range radiation or long-range radiation, the reception intensity of which is decisive for the feasibility of certain control commands is.

Die Empfangseinheit 11 weist ein sogenanntes Infrarotauge A zum Empfang der von den Dioden D1, D2 und D3 ausgesendeten Strahlungen auf, das einen der jeweils empfangenen Strahlung entsprechenden Strom erzeugt. Dieser Strom passiert ein Frequenzfilter F um störendes Fremdlicht von anderer Frequenz als derjenigen der Steuerstrahlung, der Nahbereichsstrahlung und der Fernbereichsstrahlung auszuschließen.The receiving unit 11 has a so-called infrared eye A for receiving the radiation emitted by the diodes D1, D2 and D3, which generates a current corresponding to the radiation received in each case. This current passes through a frequency filter F in order to exclude disturbing extraneous light from a frequency other than that of the control radiation, the short-range radiation and the long-range radiation.

Aus dem Frequenzfilter F gelangt der Strom in einen Komparator K, der die sich in der Stärke des Stromes manifestierende Intensität der empfangenen Strahlung prüft und das Signal nur weitergibt, wenn diese Intensität einen bestimmten Schwellwert überschreitet. Der durchgelassene Strom aktiviert aufgrund der in ihm enthaltenen Addresse jeweils nur das ihm adressenmäßig zugeordnete von drei ICs E1, E2 und E3, die einzeln mit den ICs S1 bzw. S2 bzw. S3 der Sendeeinheit 10 zusammenarbeiten. Das IC E1 ist dabei mittels eines Kodierschalters C' auf die gleiche Addresse eingestellt wie das IC S1 in der Sendeeinheit 10, und die ICs E2 und E3 haben die gleiche Addresse verdrahhtet wie die ICs S2 und S3.The current passes from the frequency filter F into a comparator K, which checks the intensity of the radiation received, which manifests itself in the strength of the current, and only passes on the signal if this intensity exceeds a certain threshold value. Due to the address contained in it, the let-through current only activates the one of three ICs E1, E2 and E3 assigned to it in terms of address, which individually work together with the ICs S1 or S2 or S3 of the transmission unit 10. The IC E1 is set to the same address as the IC S1 in the transmission unit 10 by means of a coding switch C ', and the ICs E2 and E3 have the same address wired as the ICs S2 and S3.

Die von den ICs E1, E2 und E3 ausgegebenen Signale werden in einer Logikeinheit L so verknüpft, daß die oben beschriebene Steuersignalerzeugung und -unterdrückung abhängig von den Datensignalen in der Steuerstrahlung und der Empfangsintensität der Nahbereichsstrahlung und der Fernbereichsstrahlung durchgeführt wird. Die Logikeinheit L liefert die entsprechenden elektrischen Steuersignale an Steuereinheiten St, die den jeweiligen Befehl bei dem Bodenverdichtungsgerät BV ausführen.The signals output by the ICs E1, E2 and E3 are linked in a logic unit L in such a way that the control signal generation and suppression described above is carried out as a function of the data signals in the control radiation and the reception intensity of the short-range radiation and the long-range radiation. The logic unit L supplies the corresponding electrical control signals to control units St, which execute the respective command at the soil compacting device BV.

Da die Lichtsendedioden D1, D2 und D3 zeitlich nacheinander angesteuert werden, könnten sie auch durch eine einzige Infrarotlicht emitierende Diode ersetzt werden, die von allen ICs S1, S2 und S3 angesteuert wird.Since the light-emitting diodes D1, D2 and D3 are activated one after the other in time, they could also be replaced by a single infrared light-emitting diode which is activated by all ICs S1, S2 and S3.
