Description

Die Erfindung betrifft eine Sicherheitsschaltung für eine elektrische Antriebsvorrichtung zum Öffnen und Schließen des Lukendeckels an einer Ein-/Ausstiegsluke eines Kampffahrzeugs, wobei die elektrische Antriebsvorrichtung über eine Lastversorgungsleitung und eine Ein-/Ausschaltvorrichtung an eine Laststromquelle angeschlossen ist und ein im Bereich der Ein-/Ausstiegsluke angeordneter, manuell betätigbarer Steuerschalter eine Steuerspannung liefert zur Sperrung oder Freigabe der elektrischen Antriebsvorrichtung.The invention relates to a safety circuit for an electric drive device for opening and closing the hatch cover at an entrance / exit hatch of a combat vehicle, wherein the electric drive device is connected via a load supply line and an on / off device to a load power source and a Exit hatch arranged, manually operable control switch provides a control voltage for blocking or release of the electric drive device.

Ein-/Ausstiegsluken an Kampffahrzeugen sind allgemein bekannt, insbesondere Ein-/Ausstiegsluken, die einen Lukendeckel aufweisen, welcher oberhalb des oberen Randes einer Lukenöffnung angeordnet und zum Öffnen und Schließen parallel zur Ebene der Lukenöffnung bewegbar ist.Entry / exit hatches on combat vehicles are well known, in particular entry / exit hatches, which have a hatch cover, which is arranged above the upper edge of a hatch opening and movable for opening and closing parallel to the plane of the hatch opening.

Derartige Ein-/Ausstiegsluken sind beispielsweise in DE 3 305 882 A1 , DE 4 240 140 A1 und DE 19504922 A1 beschrieben.Such entry / exit hatches are, for example, in DE 3 305 882 A1 . DE 4 240 140 A1 and DE 19504922 A1 described.

Bei derartigen Ein-/Ausstiegsluken ist es für die Sicherheit der Besatzung von großer Bedeutung, dass der Lukendeckel nicht auf- oder zugefahren werden kann, wenn sich noch Teile einer Person im Bereich der Lukenöffnung befinden, da sonst schwere Verletzungen zu befürchten sind. Aus diesem Grunde weist jede Luke einen Steuerschalter auf, der manuell betätigbar ist und ein Steuerspannungssignal liefert zur Sperrung oder Freigabe der elektrischen Antriebsvorrichtung für den Lukendeckel. Dieser Steuerschalter ist im allgemeinen so ausgebildet und angeordnet, dass nach seiner Betätigung sichergestellt ist, dass sich keine Person mehr im Bewegungsbereich des Lukendeckels befinden kann. Zu diesem Zweck ist der Steuerschalter beispielsweise mit einem Sicherheitsrollo gekoppelt, das sich in der Lukenöffnung unterhalb der Bewegungsbahn des Lukendeckels befindet und manuell auf- und zuziehbar ist. Nur wenn dieses Sicherheitsrollo zugezogen ist und somit in den Schließweg des Lukendeckels nicht mehr hineingegriffen werden kann, gibt der Steuerschalter ein Freigabesignal für die elektrische Antriebsvorrichtung.In such entry / exit hatches, it is for the safety of the crew of great importance that the hatch cover can not be opened or closed, if there are still parts of a person in the hatch opening, otherwise serious injuries are to be feared. For this reason, each hatch has a control switch which is manually operable and provides a control voltage signal for blocking or enabling the electric drive device for the hatch cover. This control switch is generally designed and arranged so that it is ensured after its operation that no person can be located in the range of movement of the hatch cover. For this purpose, the control switch is coupled, for example, with a safety roller blind, which is located in the hatch opening below the movement path of the hatch cover and manually on and is zuziehbar. Only when this safety roller blind is closed and thus can no longer be grasped into the closing path of the hatch cover, the control switch gives an enable signal for the electric drive device.

Es hat sich nun gezeigt, dass gefährliche Situationen entstehen können, wenn beispielsweise das Fahrzeug bei halbgeöffnetem Lukendeckel abgeschaltet wird und sich das ganze System in einem undefinierten Zustand befindet.It has now been shown that dangerous situations can arise when, for example, the vehicle is switched off when the hatch cover is half open and the entire system is in an undefined state.

Wenn dann später der Fahrzeughauptschalter betätigt wird, kann es geschehen, dass die Luke sofort beim Einschalten zugefahren wird und entsprechend Verletzungen entstehen können.If the vehicle main switch is then actuated later, the hatch can be closed immediately when it is switched on and injuries may occur.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherheitsschaltung der eingangs erwähnten Art zu schaffen, welche sicherstellt, dass die elektrische Antriebsvorrichtung zum Öffnen und Schließen des Lukendeckels in jeder Situation, also auch beim Start des Fahrzeugs mit halbgeöffnetem Lukendeckel, erst freigegeben wird, wenn der Steuerschalter mindestens einmal betätigt worden ist, womit verhindert wird, dass beim Starten des Fahrzeugs ohne Zutun der Besatzung der Lukendeckel zufährt.The invention has for its object to provide a safety circuit of the type mentioned, which ensures that the electric drive device for opening and closing the hatch cover in any situation, including the start of the vehicle with half-hatch, only released when the control switch has been actuated at least once, thus preventing the hatch cover from moving when the vehicle is started without any intervention from the crew.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1. Eine vorteilhafte Weiterbildung der Erfindung ist im abhängigen Anspruch beschrieben.The solution of this object is achieved according to the invention with the features of the characterizing part of claim 1. An advantageous development of the invention is described in the dependent claim.

Ein Grundgedanke der Erfindung besteht darin, die Sicherheitsschaltung als Relaisschaltung auszubilden. Es wäre wohl grundsätzlich möglich, hier eine Schaltung aus anderen steuerbaren Schaltelementen aufzubauen, oder die Sicherheit durch eine entsprechende Software im Steuersystem zu gewährleisten. Es hat sich aber herausgestellt, dass diese Lösungen störanfällig sind und insbesondere der geforderte Temperaturbereich, innerhalb dessen die Schaltung oder das System fehlerfrei arbeiten muß, nur schwer eingehalten werden kann. Weiterhin haben sich diese Lösungen als kostenaufwendig erwiesen.A basic idea of the invention is to design the safety circuit as a relay circuit. It would probably be possible in principle to build a circuit of other controllable switching elements, or to ensure the security of a corresponding software in the control system. However, it has been found that these solutions are prone to failure and in particular the required temperature range within which the circuit or the system must work properly, can be met only with difficulty. Furthermore, these solutions have proven to be costly.

Die Lösung als Relaisschaltung ist dagegen einfach und robust aufzubauen und wenig störungsanfällig, insbesondere bei extremen Temperaturen.The solution as a relay circuit, however, is simple and robust to build and little susceptible to interference, especially at extreme temperatures.

Die jeweilige Stellung der Relais kann durch eine entsprechende Software überwacht werden.The respective position of the relays can be monitored by appropriate software.

Im folgenden wird anhand der beigefügten Zeichnungen ein Ausführungsbeispiel für die erfindungsgemäße Sicherheitsschaltung und ihre Funktionsweise näher erläutert.In the following an embodiment of the safety circuit according to the invention and its operation will be explained in more detail with reference to the accompanying drawings.

In den Zeichnungen zeigen

  • Fig.1 eine als Relaisschaltung ausgebildete Sicherheitsschaltung im Schaltbild;
  • Fig. 2 und 3 den zeitlichen Verlauf einiger Spannungen an der Schaltung gemäß Fig. 1 ausgelöst von einer positiven oder negativen Flanke der Steuerspannung.
In the drawings show
  • Fig.1 a trained as a relay circuit safety circuit in the diagram;
  • FIGS. 2 and 3 the time course of some voltages on the circuit according to Fig. 1 triggered by a positive or negative edge of the control voltage.

Die in Fig. 1 dargestellte Relaisschaltung besitzt ein erstes Relais K5 mit einem Selbsthaltekreis SH, dessen Arbeitskontakt K5 - A1A2 in der Lastversorgungsleitung LV liegt, die über einen Hauptschalter S1 an eine Spannungsquelle U0 zur Zuführung einer Lastversorgungsspannung U1 anschließbar ist. Vom Arbeitskontakt K5 - A1A2 wird dann die Lastspannung U2 abgegeben und der elektrischen Antriebsvorrichtung zum Öffnen und Schließen des Lukendeckels zugeführt.
Der Steuereingang X1 des ersten Relais K5 ist über einen Arbeitskontakt K4 - A1A2 eines zweiten Relais K4 und einen Ruhekontakt K3-A2A3 eines dritten Relais K3 in Serienschaltung mit der Lastversorgungsleitung LV verbunden. Der Steuereingang X1 des zweiten Relais K4 ist über den Arbeitskontakt K2-A1A2 an eine Versorgungsspannungsquelle U4 angeschlossen, wobei dieses vierte Relais K2 als abfallverzögertes Zeitrelais ausgebildet ist. Der Steuereingang X1 des dritten Relais K3 ist über den Arbeitskontakt K1 - A1A2 eines fünften Relais K1 an einen Steuerschalter S2 angeschlossen, wobei das fünfte Relais K1 als anzugverzögertes Zeitrelais ausgebildet ist. Die Steuereingänge K2 - X3 und K1 - X1 des vierten und fünften Relais K2 beziehungsweise K1 sind ebenfalls an den Steuerschalter S2 angeschlossen.In the Fig. 1 relay circuit shown has a first relay K5 with a self-holding circuit SH, the normally open contact K5 - A1A2 is located in the load supply line LV, which is connected via a main switch S1 to a voltage source U0 for supplying a load supply voltage U1. From the normally open contact K5 - A1A2, the load voltage U2 is then output and fed to the electric drive device for opening and closing the hatch cover.
The control input X1 of the first relay K5 is connected in series with the load supply line LV via a normally open contact K4-A1A2 of a second relay K4 and a normally closed contact K3-A2A3 of a third relay K3. The control input X1 of the second relay K4 is connected via the normally open contact K2-A1A2 to a supply voltage source U4, wherein this fourth relay K2 is designed as a time delay relay delayed. The control input X1 of the third relay K3 is connected via the normally open contact K1-A1A2 of a fifth relay K1 to a control switch S2, the fifth relay K1 being designed as a time-delayed relay. The control inputs K2 - X3 and K1 - X1 of the fourth and fifth relays K2 and K1 are also connected to the control switch S2.

Der Steuerschalter S2 ist in nicht eigens dargestellter Weise mit einem Sicherheitsrollo verbunden, das an der Ein-/Ausstiegsluke des Kampffahrzeugs unterhalb der Bewegungsbahn des Lukendeckels angeordnet und manuell auf- und zuziehbar ist. Bei der Betätigung des Steuerschalters S2 wird jeweils ein Steuerspannungssignal U3 ein- oder ausgeschaltet, womit jeweils eine positive oder negative Signalflanke entsteht.The control switch S2 is connected in a manner not specifically shown with a safety roller, which is arranged at the entrance / exit hatch of the combat vehicle below the movement path of the hatch cover and manually auf- and pulled up. Upon actuation of the control switch S2, in each case a control voltage signal U3 is switched on or off, whereby in each case a positive or negative signal edge is formed.

Die Funktionsweise der in Fig. 1 dargestellten Schaltung wird im folgenden auch anhand der Figuren 2 und 3 erläutert. Es wird beim Einschalten zunächst die Versorgungsspannung U4 angelegt und sodann durch Betätigung des Hauptschalters S1 von der Spannungsquelle U0 die Lastversorgungsspannung U1 eingeschaltet. In diesem Zustand wird noch keine Lastspannung U2 zum Antrieb hin abgegeben.
Wird der Steuerschalter S2 in der Weise betätigt, dass die Steuerspannung U3 von "0" nach "1" ansteigt, so zieht das vierte Relais K2 sofort an, während das fünfte Relais K1 zeitverzögert anzieht. Durch das somit über die Steuerleitungen ST3 und ST1 laufende Steuersignal zieht das zweite Relais K4 sofort an, während das dritte Relais K3 infolge der Zeitverzögerung an K1 zeitverzögert anzieht. Dies hat zur Folge, dass die Lastversorgungsspannung U1 über das erste Relais K5 sofort durchgeschaltet wird und infolge des Selbsthaltekreises SH gehalten wird. Somit steht die Lastspannung U2 zur Verfügung bis mittels des Hauptschalters S1 die Lastversorgungsspannung U1 ausgeschaltet wird.The functioning of in Fig. 1 The circuit shown below is also based on the FIGS. 2 and 3 explained. When switching on, the supply voltage U4 is initially applied, and then the load supply voltage U1 is switched on by actuation of the main switch S1 by the voltage source U0. In this state, no load voltage U2 is still delivered to the drive.
If the control switch S2 is actuated in such a manner that the control voltage U3 rises from "0" to "1", the fourth relay K2 picks up immediately, while the fifth relay K1 attracts with a time delay. As a result of the control signal thus running via the control lines ST3 and ST1, the second relay K4 immediately picks up, while the third relay K3 attracts with a time delay as a result of the time delay at K1. This has the consequence that the load supply voltage U1 is switched through immediately via the first relay K5 and as a result of the self-holding circuit SH is held. Thus, the load voltage U2 is available until the load supply voltage U1 is turned off by means of the main switch S1.

Diese Vorgänge sind im Zeitdiagramm nach Fig. 2 dargestellt.These processes are in the time diagram after Fig. 2 shown.

Bei einem Abfall der Steuerspannung U3 von "1" nach "0", fällt das fünfte Relais K1 sofort ab, während das vierte Relais K2 zeitverzögert abfällt. Dies hat zur Folge, dass auch das dritte Relais K3 sofort abfällt, während das zweite Relais K4 zeitverzögert abfällt. Dies hat zur Folge, dass infolge des über die Steuerleitung ST2 durchlaufenden Steuersignals mittels des ersten Relais K5 die Lastversorgungsspannung U1 durchgeschaltet wird und als Lastspannung U2 für den Antrieb zur Verfügung steht bis mittels des Hauptschalters S1 die Lastversorgungsspannung U1 ausgeschaltet wird. Diese Vorgänge sind im Zeitdiagramm gemäß Fig. 3 dargestellt. Wie der Schaltung und den Diagrammen abzulesen, haben nach einer ersten Änderung der Steuerspannung U3 weitere Änderungen der Steuerspannung keinen Einfluß mehr auf die Lastspannung U2.If the control voltage U3 falls from "1" to "0", the fifth relay K1 drops immediately, while the fourth relay K2 drops in a time-delayed manner. This has the consequence that the third relay K3 drops immediately, while the second relay K4 drops with a time delay. As a result, as a result of the control signal passing through the control line ST2, the load supply voltage U1 is turned on by means of the first relay K5 and the load voltage U2 for the drive is available until the load supply voltage U1 is switched off by means of the main switch S1. These processes are in accordance with the time diagram Fig. 3 shown. As can be seen from the circuit and the diagrams, after a first change in the control voltage U3 further changes in the control voltage have no influence on the load voltage U2.

Somit bilden das zweite Relais K4 und das dritte Relais K3 zusammen eine Exklusive-ODER-Schaltung, während durch das erste Relais K5 mit Selbsthaltekreis eine Speicherschaltung realisiert ist.Thus, the second relay K4 and the third relay K3 together form an exclusive-OR circuit, while a memory circuit is realized by the first relay K5 with self-holding circuit.

Das erste Relais K5 sowie das zweite Relais K4 und das dritte Relais K3 können jeweils Prüfkontakte B1, B2, B3 beziehungsweise C1, C2, C3 enthalten, über welche die jeweiligen Stellungen dieser Relais festgestellt und einer Software-gesteuerten Prüfeinrichtung zugeführt werden können. Durch die dargestellte Schaltung ist sichergestellt, dass die Lastspannung U2 nur angelegt wird, wenn vorher der Steuerschalter S2 in einer der beiden Richtungen betätigt worden ist, das heißt, dass das entsprechende Sicherheitsrollo geöffnet oder geschlossen worden ist.The first relay K5 and the second relay K4 and the third relay K3 may each contain test contacts B1, B2, B3 or C1, C2, C3, via which the respective positions of these relays can be determined and fed to a software-controlled test device. The illustrated circuit ensures that the load voltage U2 is only applied, if previously the control switch S2 has been operated in one of the two directions, that is, that the corresponding safety blind has been opened or closed.
