Description

Die Erfindung betrifft eine redundante Überwachungseinrichtung entsprechend dem Oberbegriff des ersten Patentanspruches.The invention relates to a redundant monitoring device according to the preamble of the first claim.

Die Erfindung ist überall dort anwendbar, wo Steuerventile, vorzugsweise Magnetventile durch Brandmelde- und Feuerlöschzentralen, überwacht werden müssen. Die vorgeschlagene Art der Überwachung ist besonders dann sinnvoll, wenn Anlagen vorhanden sind, bei denen ein Ausfall eines Verbrauchers mehrere weitere Ausfälle nach sich zieht. Das ist z. B. bei Mehrbereichslöschanlagen der Fall, bei denen nur ein Steuerventil vorhanden ist. Fällt dieses Ventil zu 100 % aus, kann kein weiterer Löschbereich mehr angesteuert werden. Die Überwachung aller an eine Brandmeldezentrale angeschlossenen Verbraucher, die eine Löschanlage steuern, wird durch den Verband der Sachversicherer vorgeschrieben. Diese Überwachung soll sicherstellen, daß alle Komponenten einer Brandmelde- bzw. Löschanlage zu jedem Zeitpunkt einsatzbereit sind oder ggf. eine kurzfristige Instandhaltung gewährleistet werden kann.The invention is applicable wherever control valves, preferably solenoid valves by fire detection and fire extinguishing centers, must be monitored. The proposed type of monitoring is particularly useful when facilities are present in which a loss of a consumer causes several more failures. This is z. As in multi-range extinguishing systems of the case in which only one control valve is present. If this valve fails to 100%, no further extinguishing area can be controlled. The monitoring of all consumers connected to a fire alarm control panel controlling an extinguishing system is prescribed by the Association of Property Insurers. This monitoring should ensure that all components of a fire alarm or extinguishing system are ready for use at any time or, if necessary, that a short-term maintenance can be guaranteed.

Um die Funktionalität von Steuerventilen von Feuerlöschanlagen zu überwachen, sind einfache Überwachungswege Spannungspolung oder Impulsauswertung bekannt. Diese haben den Nachteil, daß bei ihrem Ausfall keine Funktionalität des Steuerventils mehr gegeben ist.To monitor the functionality of control valves of fire extinguishing systems, simple monitoring paths voltage polarization or pulse evaluation are known. These have the disadvantage that in their failure no functionality of the control valve is given more.

Es ist daher Aufgabe der Erfindung, eine redundante Überwachungseinrichtung für Brandmelde- und Feuerlöschzentralen für die elektrische Funktion von Steuerventilen von Feuerlöschanlagen zu entwickeln, wobei der Schaltungsaufwand und die Baugröße minimal sein sollen.It is therefore an object of the invention to develop a redundant monitoring device for fire alarm and fire extinguishers for the electrical function of control valves of fire extinguishing systems, the circuit complexity and size should be minimal.

Diese Aufgabe wird durch eine redundante Überwachungseinrichtung nach den kennzeichnenden Merkmalen des ersten Patentanspruches gelöst.
Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.This object is achieved by a redundant monitoring device according to the characterizing features of the first claim.
Subclaims give advantageous embodiments of the invention again.

Die erfindungsgemäße Lösung sieht vor, daß zwischen zwei Steuergruppen einer Brandmelde- und Feuerlöschzentrale und zwei Überwachungskreisen mindestens zwei separate Leitungen bestehen, die zu Anschlußklemmen führen. An diesen Anschlußklemmen ist ein Überwachungsmodul angeordnet, mit dem es möglich ist, Steuerventile redundant zu überwachen und das Modul so klein zu halten, daß es in einen Ventilstecker zu montieren ist. Die Überwachung des Ventils erfolgt durch zwei Steuergruppen. Diese Gruppen basieren auf dem Prinzip der Spannungsüberwachung und werden im Auslösefall parallel angesteuert. Die Überwachung des Ventils erfolgt direkt im Anschlußstecker des Ventils. Das Modul beinhaltet zwei Überwachungskreise, an deren Ende Gabelkontakte für einen Plus- und Minuspol angeordnet sind. Zwischen beiden Überwachungskreisen ist eine Spule des zu überwachenden Ventils geschaltet ist. Nach den Anschlußklemmen und innerhalb des Überwachungsmoduls bilden jeweils gleichpolige Leitungen separate Überwachungskreise, in denen Low-Side-Schalter angeordnet und Entkopplungsdioden in Reihe geschaltet sind. Die Entkopplungsdioden, die in Reihe geschaltet sind, sind nur in einem Überwachungskreis angeordnet. Zwischen den beiden Überwachungskreisen sind Darlington-Transistoren angeordnet.The solution according to the invention provides that between two control groups of a fire alarm and fire extinguisher and two monitoring circuits consist of at least two separate lines leading to terminals. At these terminals, a monitoring module is arranged, with which it is possible to monitor control valves redundant and keep the module so small that it is to be mounted in a valve plug. The valve is monitored by two valves Control groups. These groups are based on the principle of voltage monitoring and are triggered in parallel in the event of tripping. The valve is monitored directly in the connector of the valve. The module contains two monitoring circuits, at the end of which fork contacts for a plus and minus pole are arranged. Between both monitoring circuits, a coil of the valve to be monitored is connected. After the terminals and within the monitoring module, each of the same-pole lines form separate monitoring circuits, in which low-side switches are arranged and decoupling diodes are connected in series. The decoupling diodes, which are connected in series, are arranged only in a monitoring circuit. Between the two monitoring circuits Darlington transistors are arranged.

Die zwei separaten Überwachungskreise des Moduls dienen der gemeinsamen Überwachung der Spule des Ventils sowie des Weges von der Brandmelde- bzw. Steuerzentrale zum Verbraucher auf Drahtbruch oder Kurzschluß. Die Überwachung vom Kreis 1 erfolgt im wesentlichen durch eine Entkopplungsdiode und anschließend durch die Ventilspule. Da nach der Spule eine Ableitung von 0 V (Ground) vorhanden ist, kann über einen Spannungsleiter ein Darlington-Transistor angesteuert werden. Dieser Transistor schaltet den eigentlichen Anschlußwiderstand des Überwachungskreises in den Überwachungsweg. Die Überwachung von Kreis 2 erfolgt auf die gleiche Weise wie Kreis 1, nämlich ebenfalls durch die Ventilspule. Wird der Stecker vom Ventil abgezogen und somit ein Drahtbruch in der Ventilzuleitung erzeugt, schließen beide Darlington-Transistoren und auch beide Überwachungskreise, und es wird durch das Abschalten der Endwiderstände ein Drahtbruch erzeugt.The two separate monitoring circuits of the module are used for common monitoring of the coil of the valve as well as the way from the fire alarm or control center to the consumer to wire break or short circuit. The monitoring of the circuit 1 takes place essentially by a decoupling diode and then by the valve coil. Since there is a derivative of 0 V (ground) after the coil, a Darlington transistor can be controlled via a voltage conductor. This transistor switches the actual connection resistance of the monitoring circuit in the monitoring path. The monitoring of circuit 2 takes place in the same way as circuit 1, namely also through the valve coil. If the connector is removed from the valve and thus a wire break in the valve lead generated, close both Darlington transistors and both monitoring circuits, and it is generated by switching off the terminating resistances a wire break.

Im Ansteuerungsfall wird je nach Kreis eine Spannung von beispielsweise +19 bis 29 V, an das Modul geschaltet, wodurch eine Zehnerdiode leitend wird und über einen Spannungsteiler wird der Low-Side-Schalter eingeschaltet. Dieser Schalter schaltet 0 V (Ground) an die Ventilspule, wodurch das Ventil öffnet und schaltet weiterhin den Darlington-Transistor aus. Durch das Abschalten des Transistors wird auch der Überwachungsanschlußwiderstand abgeschaltet. Durch diese Abschaltung wird der Abschlußwiderstand abgeschaltet und es kann keine Leistung an dem Widerstand verbraucht werden.In the drive case, depending on the circuit, a voltage of, for example, +19 to 29 V, connected to the module, whereby a zener diode is conductive and a voltage divider, the low-side switch is turned on. This switch connects 0 V (ground) to the valve spool, which opens the valve and continues to turn off the Darlington transistor. By switching off the transistor and the monitoring terminal resistance is turned off. This shutdown shuts off the termination resistor and no power can be consumed on the resistor.

Zwischen den separaten Leitungen und den Überwachungskreisen sowie zwischen der Spule und den Überwachungskreisen sind Klemmen und Gabelkontakte angeordnet. Vorteilhaft ist es, im ersten Überwachungskreis, der der Pluspolung dient, zwischen den Klemmen und dem Gabelkontakt zwei Dioden anzuordnen.Between the separate lines and the monitoring circuits and between the coil and the monitoring circuits terminals and fork contacts are arranged. It is advantageous to arrange two diodes between the terminals and the fork contact in the first monitoring circuit, which serves the positive polarity.

Im zweiten Überwachungskreis für die negative Polung sind Low-Side-Schalter zwischen den Klemmen und den Gabelkontakten anzuordnen.In the second monitoring circuit for the negative polarity, low-side switches must be arranged between the terminals and the fork contacts.

Die Darlington-Transistoren sind unmittelbar nach den Klemmen anzuordnen. Weiterhin ist es vorteilhaft, zwischen den separaten Überwachungskreisen mindestens eine Diode anzuordnen. Darüber hinaus ist es vorteilhaft, zwischen den separaten Überwachungskreisen eine Diode und eine Leuchtdiode anzuordnen.The Darlington transistors should be located immediately after the terminals. Furthermore, it is advantageous to arrange at least one diode between the separate monitoring circuits. In addition, it is advantageous to arrange a diode and a light-emitting diode between the separate monitoring circuits.

In vorteilhafter Weise wird vor den Darlington-Transistoren jeweils ein Anschlußwiderstand angeordnet.Advantageously, in each case a connection resistor is arranged in front of the Darlington transistors.

Im Folgenden wird die vorgeschlagene Lösung an einer Figur und einem Ausführungsbeispiel näher erläutert.The proposed solution to a figure and an embodiment will be explained in more detail below.

Die Figur zeigt das Blockdiagramm der Karte der redundanten Überwachung eines Magnetventils 17 für eine Feuerlöschanlage durch eine Brandmelde- und Steuerzentrale 1. Dazu werden zwei Primärsteuerleitungen 2, 3 zu den Klemmen 6, die die Kennzeichnung X1.1, X1.2, X1.3 und X1.4 tragen, geführt. Zwischen den unterschiedlichen Polen + und - der beiden Primärleitungen 2, 3 sind nach den Klemmen 6 Anschlußwiderstände 7,8 mit Darlington-Transistoren 4,5 in Reihe geschaltet. In den Leitungen, die von X1.2 und X1.4 zum Anschluß X4 führen, sind zwei Low-Side-Schalter 9,10 angeordnet. In den Leitungen, die den anderen Überwachungskreis bilden und von X1.1 und X1.3 zu X3 führen, sind zwei Dioden 11,18 angeordnet. Zwischen beiden Überwachungskreisen ist eine Leuchtdiode 13 und parallel eine weitere Diode 12 angeordnet. Zwischen beiden Überwachungskreisen ist die Spule 16 des Magnetventils 17 angeordnet.The figure shows the block diagram of the redundant monitoring card of a solenoid valve 17 for a fire extinguishing system by a fire alarm and control center 1. For this purpose, two primary control lines 2, 3 to the terminals 6, the marking X1.1, X1.2, X1.3 and carry X1.4, guided. Between the different poles + and - of the two primary lines 2, 3, terminal resistors 7, 8 are connected in series with Darlington transistors 4 after the terminals 6. In the lines leading from X1.2 and X1.4 to terminal X4, two low-side switches 9,10 are arranged. Two diodes 11, 18 are arranged in the lines which form the other monitoring circuit and lead from X1.1 and X1.3 to X3. Between two monitoring circuits, a light emitting diode 13 and a further diode 12 is arranged in parallel. Between the two monitoring circuits, the coil 16 of the solenoid valve 17 is arranged.

Das Überwachen der Ventilspule 16 auf Drahtbruch und Kurzschluß erfolgt für beide Kreise nach dem gleichen Prinzip. Die jeweilige Überwachungsspannung wird über die Klemmen 6 (X1.1 und X1.2) eingespeist und über die Dioden 11,18 (V7, V8) gemeinsam nach 14 (X3) geschaltet. Von 14 (X3) aus wird die Überwachungsspannung durch die Spule 16 des Ventils 17 nach 14 (X4) geleitet und kann von dort aus über die Spannungsteiler R9 und R11 sowie R10 und R12 die Transistoren V9 und V10 für die jeweiligen Überwachungskreise ansteuern. Der Anschlußwiderstand 7 (R3) wird durch V9 nach 0 V (Ground) geschaltet, wobei der Überwachungsstrom durch den Anschlußwiderstand 7 (R3) fließen kann. Für den zweiten Überwachungskreis ist der Anschlußwiderstand 8 (R8) zuständig, der durch V10 gesteuert wird. Durch den Spannungsabfall an den beiden Dioden 11,12 und die Widerstände 7,8 stellt sich an den beiden Klemmen 14,15 eine Spannung ein, die durch die Auswerteelektronik der Zentrale bzw. der Steuereinrichtung 1 gemessen und ausgewertet wird.The monitoring of the valve spool 16 for wire breakage and short circuit takes place for both circuits according to the same principle. The respective monitoring voltage is fed in via the terminals 6 (X1.1 and X1.2) and connected together via the diodes 11, 18 (V7, V8) to 14 (X3). From FIG. 14 (X3), the monitoring voltage is passed through the coil 16 of the valve 17 to 14 (X4) and from there via the voltage dividers R9 and R11 and R10 and R12 to drive the transistors V9 and V10 for the respective monitoring circuits. The terminal resistor 7 (R3) is switched to 0 V (ground) by V9, and the monitor current can flow through the terminal resistor 7 (R3). For the second monitoring circuit, the connection resistor 8 (R8) is responsible, which is controlled by V10. Due to the voltage drop across the two diodes 11,12 and the resistors 7,8 at the two terminals 14,15 a voltage which is measured and evaluated by the transmitter of the control center or the control device 1.

Im Folgenden wird das Ansteuern des Ventils durch den Kreis 1 beschrieben:The following describes the activation of the valve by the circle 1:

Soll die Spule 16 des Ventils 17 durch die Primärsteuerleitung 2 an den Klemmen 6 (X1 und X2) angesteuert werden, wird durch die Zentrale bzw. Steuereinrichtung 1 eine +24 V Spannung an die Klemme 6 (X1.1) angelegt. Durch die Spannung wird die Zehnerdiode V1 des Low-Side-Schalters 9 leitend und an Pin 1 von V3 stellt sich über den Spannungsteiler R1 und R2 eine Ansteuerspannung für V3 ein. Der Kondensator C1 dient zum einen zum Glätten von Spannungsspitzen und zum anderen als Ladungsspeicher. Durch die Ansteuerung von V3 schaltet sich dieser durch und wird durch den Pin 2/1 und 3 leitend und schaltet 0 V über die Klemme 15 (X4) an die Spule 16 des Ventils 17. Dadurch wird die Ansteuerspannung des Transistors V9 des Darlington-Transistors 4 kurzgeschlossen und V9 gesperrt. Der Anschlußwiderstand 7 (R3) wird abgeschaltet, wodurch keine Verlustleistung am Anschlußwiderstand 7 (R3) entstehen kann. Gleichzeitig wird über die Dioden 7 (V8) die Spannung +24 V an die Spule 16 des Ventils 17 über die Klemme 14 (X3) geschaltet, wodurch dieses nun anzieht. Des weiteren wird die Zehnerdiode V4 leitend und die Leuchtdiode 13 beginnt zu leuchten. Die Widerstände R4 und R5 dienen als Vorwiderstände für die Leuchtdiode 13 (LED H1). Die Diode 12 (V2) dient als Freilaufdiode für die Ventilspule 16.If the coil 16 of the valve 17 is to be controlled by the primary control line 2 at the terminals 6 (X1 and X2), a +24 V voltage is applied to the terminal 6 (X1.1) by the control unit or control device 1. The voltage causes the diode diode V1 of the low-side switch 9 to conduct, and pin 1 of V3 adjusts a drive voltage for V3 via the voltage divider R1 and R2. The capacitor C1 serves on the one hand for smoothing voltage peaks and on the other hand as a charge storage. By driving V3, this turns on and becomes conductive by the pin 2/1 and 3 and switches 0 V via the terminal 15 (X4) to the coil 16 of the valve 17. Thus, the driving voltage of the transistor V9 of the Darlington transistor 4 shorted and V9 disabled. The connection resistor 7 (R3) is switched off, whereby no power loss at the connection resistor 7 (R3) can arise. At the same time, the voltage +24 V is connected to the coil 16 of the valve 17 via the terminal 14 (X3) via the diodes 7 (V8), whereby this now attracts. Furthermore, the zener diode V4 becomes conductive and the light-emitting diode 13 starts to light up. The resistors R4 and R5 serve as series resistors for the light-emitting diode 13 (LED H1). The diode 12 (V2) serves as a freewheeling diode for the valve spool 16.

Im Folgenden wird das Ansteuern des Ventils 17 durch Kreis 2 beschrieben. Soll die Spule 16 des Ventils 17 durch die Primärsteuerleitung 3 an den Klemmen 6 (X1.3 und X1.4) angesteuert werden, wird durch die Zentrale bzw. Steuereinrichtung 1 eine +24 V-Spannung an die Klemme 14 (X1.3) angelegt. Durch die Spannung wird die Zehnerdiode V6 des Low-Side-Schalters 10 leitend und an Pin 1 von V5 stellt sich über den Spannungsteiler R6 und R7 eine Ansteuerspannung für V5 ein. Durch die Ansteuerung von V3 schaltet der Kondensator C3 durch und wird zwischen den Pins 4/2 und 3 leitend und schaltet 0 V an die Spule 16 des Ventils 17 über die Klemme 15 (X4). Dadurch wird die Ansteuerspannung des Transistors V10 (Darlington-Transistor 5) kurzgeschlossen und V10 sperrt. Der Anschlußwiderstand 8 (R8) wird abgeschaltet, wodurch keine Verlustleistung an 8 (R8) entstehen kann. Gleichzeitig wird über die Diode 11 (V7) die Spannung von +24 V an die Spule 16 des Ventils 17 über den Gabelkontakt 15 (X4) geschaltet, wodurch die Spule 16 nun anzieht. Des weiteren wird die Z-Diode V4 leitend und die Leuchtdiode 13 beginnt zu leuchten. Die Widerstände R4 und R5 dienen als Vorwiderstände für die Leuchtdiode 13. (LED H1). Die Diode 12 (V2) dient als Freilaufdiode für die Ventilspule 16.The driving of the valve 17 by circuit 2 will be described below. If the coil 16 of the valve 17 is to be controlled by the primary control line 3 at the terminals 6 (X1.3 and X1.4), a +24 V voltage is applied to the terminal 14 (X1.3) by the control unit or control device 1 created. Due to the voltage, the Zener diode V6 of the low-side switch 10 is turned on and pin 1 of V5 adjusts itself via the voltage divider R6 and R7 a drive voltage for V5. By driving V3, the capacitor C3 turns on and becomes conductive between the pins 4/2 and 3 and switches 0 V to the coil 16 of the valve 17 via the terminal 15 (X4). As a result, the drive voltage of the transistor V10 (Darlington transistor 5) is short-circuited and V10 blocks. The connection resistor 8 (R8) is switched off, whereby no power loss at 8 (R8) can occur. At the same time, the voltage of +24 V is connected to the coil 16 of the valve 17 via the fork contact 15 (X4) via the diode 11 (V7), whereby the coil 16 now attracts. Furthermore, the Zener diode V4 becomes conductive and the light emitting diode 13 starts to light up. The resistors R4 and R5 serve as series resistors for the light emitting diode 13 (LED H1). The diode 12 (V2) serves as a freewheeling diode for the valve spool 16.

Die Überwachung des Ventils 16 erfolgt nach dem Prinzip der Spannungsüberwachung. Durch die Reihenschaltung der Entkopplungsdioden 11,18, der Ventilspule 16 und der Anschlußwiderstände 7,8 stellt sich an den Klemmen 6 des Überwachungsmoduls eine Spannung ein, die durch die Brandmelde- und Steuerzentrale 1 ausgewertet wird. Die Überwachungskreise auf dem Modul sind jeweils identisch. Die Überwachungsspannung ist von den jeweiligen Zuständen der Primärsteuerleitung 2,3 zu dem Ventil mit Spule 16,17 hin abhängig und kann sich von Ventil zu Ventil deutlich unterscheiden.The monitoring of the valve 16 is carried out according to the principle of voltage monitoring. By the series connection of the decoupling diodes 11,18, the valve coil 16 and the terminal resistors 7,8 turns on the terminals 6 of the monitoring module, a voltage which is evaluated by the fire alarm and control center 1. The monitoring circuits on the module are identical. The monitoring voltage is dependent on the respective states of the primary control line 2,3 to the valve with coil 16,17 out and can differ significantly from valve to valve.
