Abstract

Des circuits électroniques servent à commander les enroulements excitateurs de composants électromagnétiques pourvus de connexions à des circuits complémentaires, notamment des circuits en régime libre; de préférence, ces composants sont des soupapes magnétiques (MV1 à MVn) et sont connectés en série à un élément réglable de commutation (3), ce qui permet d'obtenir un réglage flexible. Afin de réduire la quantité de circuits, le coût de fabrication et le volume, les bornes (1, 4) de cette connexion en série mènent directement à un point collecteur (A, B, C); de même, les connexions (2) entre les composants (MV1 à MVn) et les éléments de réglage (3) mènent également à ces points collecteurs (A, B, C), par l'intermédiaire de diodes (D1 à Dn). Un seul circuit complémentaire (TF, CL, 10, 11) commun à tous les composants est connecté à ces points collecteurs. Les éléments du circuit complémentaire sont ainsi utilisés de façons multiples, étant donné qu'ils sont à disposition de tous les composants électromagnétiques.Electronic circuits are used to control the excitation windings of electromagnetic components provided with connections to complementary circuits, in particular free-running circuits; these components are preferably magnetic valves (MV1 to MVn) and are connected in series to an adjustable switching element (3), which makes it possible to obtain flexible adjustment. In order to reduce the quantity of circuits, the manufacturing cost and the volume, the terminals (1, 4) of this series connection lead directly to a collecting point (A, B, C); similarly, the connections (2) between the components (MV1 to MVn) and the adjustment elements (3) also lead to these collecting points (A, B, C), by means of diodes (D1 to Dn). A single complementary circuit (TF, CL, 10, 11) common to all the components is connected to these collecting points. The elements of the complementary circuit are thus used in multiple ways, since they are available to all the electromagnetic components.

Description

Elektronische Schaltungsanordnung  Electronic circuitry
Stand der Technik State of the art
Die Erfindung betrifft eine elektronische Schaltungsanordnung zur Ansteuerung von Erregerwicklungen von elektromagnetischen, mit Zusatzbeschaltung, insbesondere Freilaufkreisbeschaltung versehenen Bauelementen, vorzugsweise Magnetventilen, nach der Gattung des Hauptanspruchs. The invention relates to an electronic circuit arrangement for controlling excitation windings of electromagnetic components provided with additional circuitry, in particular free-wheeling circuitry, preferably solenoid valves, according to the preamble of the main claim.
Derartige Schaltungsanordnungen werden beispielsweise zur Ansteuerung der Erregerwicklungen von Magnetventilen verwendet, wie sie insbesondere bei der Steuerung von Einspritzsystemen für Verbrennungsmotoren eingesetzt werden. Die bei Einspritzsystemen für Verbrennungsmotoren bekannten elektronischen Schaltungsanordnungen erfordern für die Ansteuerung der Magnetventile einen relativ großen Schaltungsaufwand, so daß zum einen ein relativ hoher Erstellungspreis entsteht, andererseits jedoch auch ein entsprechender Raumbedarf für die elektronischen Bauteile zur Verfügung gestellt werden muß. Such circuit arrangements are used, for example, to control the field windings of solenoid valves, as are used in particular in the control of injection systems for internal combustion engines. The electronic circuit arrangements known in the case of injection systems for internal combustion engines require a relatively large circuit outlay for the control of the solenoid valves, so that on the one hand a relatively high production price arises, but on the other hand a corresponding space requirement for the electronic components must also be made available.
Vorteile der Erfindung Advantages of the invention
Die erfindungεgemäße elektronische Schaltungsanordnung mit den im Hauptanspruch genannten Merkmalen hat demgegenüber den Vorteil, daß eine Mehrfachausnutzung der Zusatzbeschaltung für die einzelnen elektromagnetischen Bauelemente erfolgt, gleichwohl jedoch ein Ein- und Ausschalten der einzelnen elektromagnetischen Bauelemente unabhängig voneinander möglich ist. Damit ist der apparative Aufwand und somit auch der Platzbedarf verringert, gleichwohl jedoch eine flexible Steuerung geschaffen. Der erfindungsgemäße Schaltungsaufbau ist auch insofern besonders einfach, als lediglich drei unterschiedliche Sammelpunkte gebildet werden, an die dann die für sämtliche elektromagnetischen Bauelemente gemeinsame Zusatzbeschaltung angeschlossen wird. In contrast, the electronic circuit arrangement according to the invention with the features mentioned in the main claim has the advantage that the additional circuitry is used several times for the individual electromagnetic components, but nevertheless the individual electromagnetic components can be switched on and off independently of one another. This reduces the outlay on equipment and thus also the space required, but nevertheless creates flexible control. The circuit structure according to the invention is also particularly simple in that only three different collection points are formed, to which the additional circuitry common to all electromagnetic components is then connected.
Mit Vorzug ist vorgesehen, daß zwischen dem bauelementseitigen Sammelpunkt und dem diodenseitigen Sammelpunkt ein zur Zusatzbeschaltung gehörendes Freilaufschaltglied liegt. Letzteres ist vorzugsweise als Freilauftransistor ausgebildet. Mithin übernimmt die- ses Freilaufschaltglied jeweils den Freilaufström sämtlicher elektromagnetischer Bauelemente bei deren Abschaltung. It is preferably provided that a freewheeling switching element belonging to the additional circuitry lies between the component-side collecting point and the diode-side collecting point. The latter is preferably designed as a free-wheeling transistor. So this- ses freewheeling switching element each the freewheeling flow of all electromagnetic components when they are switched off.
Nach einer Weiterbildung der Erfindung ist vorgesehen, daß zwischen dem schaltelementseitigen Sammelpunkt und dem diodenseitigen Sammelpunkt ein zur Zusatzbeschaltung gehörender Löschkondensator liegt. Auch hier wird nach dem oben bereits erläuterten erfindungsgemäßen Prinzip vorgegangen, indem nämlich lediglich ein Löschkondesator vorgesehen ist, der jedoch alle elektronischen Bauelemente bedient. According to a development of the invention, it is provided that between the switching element-side collecting point and the diode-side collecting point there is an extinguishing capacitor belonging to the additional circuit. Here too, the principle according to the invention has already been explained above, namely that only one extinguishing capacitor is provided, which, however, operates all electronic components.
Durch die Erfindung läßt sich auch der betriebsspannungsquellenseitige Schaltungsaufwand erheblich vermindern, indem zwischen dem bauelementseitigen Sammelpunkt und dem schaltungselementseitigen Sammelpunkt in Reihe zur Betriebsspannungsquelle eine zur Zusatzbeschaltung gehörende Schutzdiode liegt. Diese Schutzdiode ist demgemäß als alleiniges Bauteil sämtlichen elektromagnetischen Bauelementen zugeordnet. The invention also considerably reduces the circuit complexity on the operating voltage source side, in that a protective diode belonging to the additional circuit is located in series with the operating voltage source between the component-side collection point and the circuit element-side collection point. This protective diode is accordingly assigned as the sole component to all electromagnetic components.
In gleicher Weise - wie zuvor erläutert - kann zur Betriebsspannungsquelle fernerhin mit Vorzug ein zur Zusatzbeschaltung gehörender Vorwiderstand in Reihe liegen , der demzufolge ebenfalls einer Mehrfachausnutzung unterliegt. In the same way - as explained above - a series resistor belonging to the additional circuit can also preferably be connected in series with the operating voltage source, which series resistor is consequently also subject to multiple use.
Zeichnung drawing
Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Die Figur zeigt in schematisch vereinfachter Darstellung ein Schaltbild der elektronischen Schaltungsanordnung. The invention is explained below with reference to the drawing. The figure shows a schematic diagram of a circuit diagram of the electronic circuit arrangement.
Beschreibung des Ausführungsbeispiels Description of the embodiment
Gemäß der Figur weist die elektronische Schaltungsanordnung eine Vielzahl von Magnetventilen MV1 bis MVn auf, die mit Erregerwicklungen versehene elektromagnetische Bauelemente darstellen. Die Vielzahl der Magnetventile MV1 bis MVn ist in der Figur durch die Punktreihe gekennzeichnet. Die Anfänge der einzelnen Erregerwicklungen der Magnetventile MV1 bis MVn stehen über Leitungen 1 mit einem Sammelpunkt A in Verbindung. Die Enden der Erregerwicklungen der Magnetventile MV1 bis MVn führen über Leitungen 2 zu steuerbaren Schaltelementen 3, welche als bipolare Transistoren T1 bis Tn ausgebildet sind. Demzufolge ist jedem Magnetventil MV1 bis MVn jeweils ein bipolarer Transistor T1 bis Tn zugeordnet. Die einzelnen Leitungen 2 führen über die jeweilige KollektorEmitter-Strecke der Transistoren T1 bis Tn über Leitungen 4 zu einem weiteren Sammelpunkt B. According to the figure, the electronic circuit arrangement has a multiplicity of solenoid valves MV 1 to MV n , which represent electromagnetic components provided with excitation windings. The large number of solenoid valves MV 1 to MV n is identified in the figure by the row of dots. The beginnings of the individual field windings of the solenoid valves MV 1 to MV n are connected to a collection point A via lines 1. The ends of the field windings of the solenoid valves MV 1 to MV n lead via lines 2 to controllable switching elements 3, which are designed as bipolar transistors T 1 to T n . Accordingly, each solenoid valve MV 1 to MV n is assigned a bipolar transistor T 1 to T n . The individual lines 2 lead via the respective collector-emitter path of the transistors T 1 to T n via lines 4 to a further collection point B.
Jede Leitung 2 führt zu einer Diode D1 bis Dn und von dort aus über Leitungen 5 zu einem dritten Sammelpunkt C. Each line 2 leads to a diode D 1 to D n and from there via lines 5 to a third collection point C.
An die einzelnen Sammelpunkte A, B und C sind nunmehr Komponenten einer Zusatzbeschaltung derart angeschlossen, daß diese Komponenten mit sämtlichen Magnetventilen MV1 bis MVn zusammenwirken. Demzufolge liegt eine Vielfachausnutzung der einzelnen Zusatzbeschaltungskomponenten vor. Components of an additional circuit are now connected to the individual collection points A, B and C in such a way that these components interact with all solenoid valves MV 1 to MV n . As a result there is multiple use of the individual additional wiring components.
Im einzelnen ist dabei so vorgegangen, daß zwischen dem bauelementεeitigen Sammelpunkt A und dem diodenseitigen Sammelpunkt C ein zur Zusatzbeschaltung gehörendes Freilaufschaltglied 6 liegt, das als Freilauftransistor TF ausgebildet ist. In detail, the procedure is such that between the component-side collecting point A and the diode-side collecting point C there is a free-wheel switching element 6, which is part of the additional circuit and is designed as a free-wheeling transistor T F.
Zwischen dem schaltelementseitigen Sammelpunkt B und dem diodenseitigen Sammelpunkt C ist darüber hinaus ein Löschkondensator CL geschaltet. Die konkrete Schaltungsanordnung des Freilauftransistors TF und des Löschkondensators CL ist in der Figur nicht im Detail wiedergegeben; sie wird lediglich durch die Darstellung der diese Bauteile aufnehmenden Platine 7 angedeutet. Ihre Versorgungsspannung erhält die Schaltung der Platine 7 über gestrichelt eingezeichnete Leitungen 8, die zu einer Betriebsspannungsquelle 9 führen. An extinguishing capacitor C L is also connected between the switching element-side collecting point B and the diode-side collecting point C. The specific circuit arrangement of the freewheeling transistor T F and the quenching capacitor C L is not shown in detail in the figure; it is only indicated by the representation of the circuit board 7 receiving these components. The circuit of the circuit board 7 receives its supply voltage via lines 8 shown in broken lines, which lead to an operating voltage source 9.
Der Pluspol der Betriebsspannungsquelle 9 führt zu einer Schutzdiode 10, deren anderer Anschluß zum Sammelpunkt A führt. Der Minuspol der Betriebsspannungsquelle 9 ist mit einem Vorwiderstand 11 verbunden, dessen weiterer Anschluß zum Sammelpunkt B führt. The positive pole of the operating voltage source 9 leads to a protective diode 10, the other connection of which leads to the collecting point A. The negative pole of the operating voltage source 9 is connected to a series resistor 11, the further connection of which leads to the collecting point B.
Im Detail ist im Hinblick auf die Durchlaßrichtung der einzelnen Dioden so vorgegangen, daß die Anoden der Dioden D1 bis Dn mit den Leitungen 2 und deren Katoden mit dem Sammelpunkt C in Verbindung stehen. Die Anode der Schutzdiode 10 steht mit dem Plusnol der Betriebsspannungsquelle 9 in Verbindung, während die Katode zum Sammelpunkt A führt. In detail, with regard to the forward direction of the individual diodes, the procedure is such that the anodes of the diodes D 1 to D n are connected to the lines 2 and their cathodes to the collecting point C. The anode of the protective diode 10 stands with the plus pole of the operating voltage source 9 in connection, while the cathode leads to the collecting point A.
Die Schaltungsanordnung arbeitet folgendermaßen: The circuit arrangement works as follows:
Durch Ansteuerung der einzelnen Basen der bipolaren Transistoren T1 bis Tn ist es möglich, in jeweils erforderlicher Konstellation die einzelnen Magnetventile MV1 bis MVn einzuschalten. Dieses ergibt eine flexible Steuerung des die Magnetventile Mv1 bis MVn aufweisenden Einspritzsystems für Verbrennungsmotoren. In entsprechender Weise ist eine Ausschaltung der Magnetventile MV1 bis MVn möglich, wobei über die Dioden D1 bis Dn und den Freilauftransistor TF ein Freilaufström abfließen kann. Obwohl erfindungsgemäß für die Vielzahl der Magnetventile MV1 bis MVn nur ein Freilauftransistor Tp vorgesehen ist, kann dennoch mittels entsprechender Ansteuerung seiner Basis auf jeden individuellen Schaltvorgang der bipolaren Transistoren T1 bis Tn reagiert werden. By controlling the individual bases of the bipolar transistors T 1 to T n , it is possible to switch on the individual solenoid valves MV 1 to MV n in the constellation required in each case. This results in flexible control of the injection system for internal combustion engines which has the magnetic valves Mv 1 to MV n . In a corresponding manner, the solenoid valves MV 1 to MV n can be switched off, a freewheeling current being able to flow off via the diodes D 1 to D n and the freewheeling transistor T F. Although according to the invention only one free-wheeling transistor Tp is provided for the large number of solenoid valves MV 1 to MV n , it is nevertheless possible to respond to each individual switching operation of the bipolar transistors T 1 to Tn by appropriately controlling its base.
Die dargestellte Schaltungsanordnung macht fernerhin deutlich, daß durch Einschleifung des Löschkondensators CL zwischen die Sammelpunkte B und C eine entsprechende Löschung bei der unabhängig voneinander möglichen Ausschaltung der einzelnen Magnetventile MV1 bis MVn vornehmbar ist. Auch hier ist trotz der Vielzahl der Magnetventile MV1 bis MVn lediglich ein Löschbauteil erforderlich. The circuit arrangement shown also makes it clear that by looping in the quenching capacitor C L between the collection points B and C, a corresponding quenching can be carried out when the individual solenoid valves MV 1 to MV n are switched off independently of one another. Here too, despite the large number of solenoid valves MV 1 to MV n, only one extinguishing component is required.
Fernerhin wird sowohl die Schutzdiode 10 als auch der Vorwiderstand 11 gemeinschaftlich für die Vielzahl der Magnetventile MV1 bis MVn benutzt, so daß ein optimales Verhältnis im Hinblick auf den Bauteileinsatz vorliegt, wobei gleichwohl einzelne Schaltungsteile unabhängig von anderen Schaltungsteilen gesteuert werden können. Furthermore, both the protective diode 10 and the series resistor 11 are used jointly for the large number of solenoid valves MV 1 to MV n , so that an optimal ratio with regard to the use of components is present, although individual circuit parts can still be controlled independently of other circuit parts.
