Description
Die vorliegende Erfindung betrifft ein Prozesseinrichtungssystem mit Wartungsfunktion.The present invention relates to a process device system with maintenance function.
Prozesseinrichtungen, wie zum Beispiel Brand- oder Einbruchmeldeanlagen, bestehen im Allgemeinen aus einer oder mehreren zentralen Steuereinheit(en) sowie einem oder mehreren verteilten Feldgerät(en), wie zum Beispiel Sensoren oder Aktoren. Für eine Vielzahl solcher Geräte ist in regelmäßigen Abständen eine Wartung und Funktionsprüfung durchzuführen. In der Regel umfasst solch eine Funktionsprüfung ein Auslösen des Feldgeräts.Process equipment, such as fire or burglary alarm systems, generally consist of one or more central control unit (s) and one or more distributed field devices, such as sensors or actuators. For a large number of such devices, maintenance and functional testing must be carried out at regular intervals. As a rule, such a functional test comprises triggering of the field device.
Im Normalbetrieb ist eine Reaktion der Prozesseinrichtung auf ein Auslösen eines oder mehrere Feldgeräte vorgesehen. Die Prozesseinrichtung ist dabei auf den Ernstfall hin konfiguriert, nicht auf den Wartungsfall. Beispielsweise kann eine Brandmeldeanlage so eingerichtet sein, dass das Auslösen eines zugehörigen Rauchmelders zu einer Alarmierung der Feuerwehr und/oder dem Aktivieren einer Sprinkleranlage führt. Eine Einbruchmeldeanlage kann entsprechend eingerichtet sein, gegebenenfalls automatisch einen Notruf bei der Polizei abzusetzen.In normal operation, a reaction of the process device is provided to trigger one or more field devices. The process device is configured for emergencies, not for the maintenance case. For example, a fire alarm system be set up so that the triggering of an associated smoke detector leads to an alarm of the fire department and / or the activation of a sprinkler system. A burglary alarm system can be set up accordingly, if necessary, to automatically make an emergency call to the police.
Während einer Wartung ist eine derartige Reaktion unangebracht und zumeist unerwünscht. Um sie zu verhindern, wird die gesamte Prozesseinrichtung oder ein großer Teil davon für die Dauer einer Wartung in einen gesonderten Zustand versetzt, der diese Reaktion unterbindet. Um dabei dennoch weiterhin die ursprüngliche Funktion der Prozesseinrichtung wie zum Beispiel die Brandüberwachung (z.B. durch andere, gerade nicht gewartete Feldgeräte) in einem Gebäudekomplex gewährleisten zu können, kann die Prozesseinrichtung für die Dauer der Wartung der Anlage an zentraler Stelle von einer Person überwacht werden, während eine weitere Person die eigentliche Wartung vornimmt. Dieser Aufwand ist notwendig, weil die Feldgeräte (und somit die gesamte Prozessanlage) nicht zwischen einem Auslösen zu Wartungszwecken und einem Auslösen aufgrund tatsächlich auftretender, zu überwachender Ereignisse unterscheiden können.During maintenance, such a reaction is inappropriate and mostly undesirable. In order to prevent them, the entire process device or a large part thereof is placed in a separate state for the duration of a maintenance, which prevents this reaction. In doing so, the original function of the process equipment, such as fire monitoring, still remains (For example, by other, just not serviced field devices) to ensure in a building complex, the process device can be monitored for the duration of the maintenance of the system in a central location of one person, while another person performs the actual maintenance. This effort is necessary because the field devices (and thus the entire process plant) can not differentiate between triggering for maintenance purposes and triggering due to actually occurring events to be monitored.
Alternativ kann die Wartung von der Steuerungseinheit reguliert werden. In diesem Fall legt die Steuerungseinheit fest, welches Feldgerät geprüft wird, und schaltet dieses dann über einen Datenbus in einen Prüfmodus. In der Druckschrift

Es ist wünschenswert, die Wartung von Prozesseinrichtungen effizienter zu gestalten.It is desirable to make the maintenance of process equipment more efficient.
Erfindungsgemäß wird ein Prozesseinrichtungssystem mit Wartungsfunktion mit mindestens einem Prüfgerät und mindestens einem Feldgerät mit den Merkmalen des unabhängigen Patentanspruchs 1 vorgeschlagen.According to the invention, a process device system with a maintenance function with at least one test device and at least one field device with the features of independent patent claim 1 is proposed.
Vermöge der beanspruchten Merkmale sind das Prüfgerät und das Feldgerät so aufeinander abgestimmt, dass eine mittels eines Prüfgerätes vorgenommene Wartung des Feldgeräts in einer Prozesseinrichtung automatisch erkannt werden kann und eine zugehörige Steuereinrichtung entsprechend informiert wird und reagieren kann. Die Auswahl des zu prüfenden Feldgeräts kann dabei dezentral, beispielsweise also von Seiten des Prüfenden erfolgen.By virtue of the claimed features, the test apparatus and the field device are matched to one another such that maintenance of the field device carried out by means of a test device can be automatically detected in a process device and an associated control device is appropriately informed and able to react. The selection of the field device to be tested can be decentralized, for example by the examiner.
Das erfindungsgemäße Prozesseinrichtungssystem umfasst eine Prozesseinrichtung mit einem oder mehreren Feldgerät(en) und mit mindestens einer Steuerungseinheit. Beispiele für solch eine Prozesseinrichtung sind Brand- oder Einbruchmeldeanlagen oder auch Temperatur-, Druck- oder Wasserstandskontrollsysteme, die in verschiedenen Räumen oder Zellen eines Gebäudes oder einer Anlage Feldgeräte wie Rauchmelder, Bewegungs- oder Temperatursensoren aufweisen und von einer oder mehreren Steuergeräten gesteuert werden. Das oder die Feldgeräte können über ein Kommunikationssystem wie beispielsweise einen verdrahteten oder drahtlosen Datenbus oder ein optisches System miteinander und/oder mit der Steuerungseinheit verbunden sein.The process device system according to the invention comprises a process device with one or more field devices and with at least one control unit. Examples of such a process device are fire or burglar alarm systems or even temperature, pressure or water level control systems, the field devices such as smoke detectors, motion or temperature sensors in different rooms or cells of a building or a plant and controlled by one or more controllers. The field device or devices may be connected to each other and / or to the control unit via a communication system such as a wired or wireless data bus or an optical system.
Das erfindungsgemäße Prozesseinrichtungssystem umfasst weiterhin mindestens ein Prüfgerät zur Wartung des oder wenigstens eines der Feldgeräte. Handelt es sich bei der Prozesseinrichtung um eine Brandmeldeanlage und bei dem Feldgerät um einen automatischen Rauchmelder, kann das Prüfgerät beispielsweise für die Wartung ein Aerosol in die Rauchkammer des Rauchmelders leiten und prüfen, ob der Rauchmelder funktionsgemäß einen Alarm auslöst.The process device system according to the invention furthermore comprises at least one test device for the maintenance of the or at least one of the field devices. If the process device is a fire alarm system and the field device is an automatic smoke detector, the test device may, for example, conduct an aerosol into the smoke chamber of the smoke detector for maintenance and check whether the smoke detector functionally triggers an alarm.
Das mindestens eine Prüfgerät und das mindestens eine Feldgerät des erfindungsgemäßen Prozesseinrichtungssystems sind eingerichtet, die Steuerungseinheit über eine anstehende oder eine begonnene Wartung des Feldgeräts durch das Prüfgerät zu informieren.The at least one test device and the at least one field device of the process device system according to the invention are set up to inform the control unit about an upcoming or started maintenance of the field device by the test device.
Auf diese Weise können das oder die Steuergerät(e) der Prozesseinrichtung automatisch eine anstehende oder bereits in der Durchführung befindliche Wartung eines einzelnen Feldgeräts erkennen und darauf angemessen reagieren. Demgegenüber kann auf alarmierende Signale von gerade nicht gewarteten Feldgeräten korrekt reagiert werden. Auf diese Weise kann die Prozesseinrichtung so automatisiert werden, dass sie auch während der Wartung sicher arbeitet. Auf eine Überwachung der Wartung durch eine Person kann so verzichtet werden. Dadurch können Kosten eingespart werden.In this way, the controller or the control device (s) of the process device can automatically detect a pending or already in the running maintenance of a single field device and react appropriately. On the other hand, it is possible to react correctly to alarming signals from field devices that have just not been maintained. In this way, the process equipment can be automated to operate safely even during maintenance. On a monitoring of the maintenance by a person can be dispensed with. This can save costs.
Mehrere verschiedene Möglichkeiten des Informierens können von Prüfgerät und/oder Feldgerät parallel verwendet werden. Dadurch kann Redundanz erzeugt werden, die für größere Sicherheit beispielsweise bei Ausfall eines Kommunikationskanals sorgt.Several different ways of informing can be used by the tester and / or field device in parallel. As a result, redundancy can be generated, which ensures greater security, for example, in the event of a communication channel failure.
Die Information über die anstehende oder begonnene Wartung kann in einer gesonderten Meldung an die Steuerungseinheit übermittelt werden. Alternativ oder zusätzlich kann die Information einer Nachricht angefügt werden, die auch im Normalfall an die Steuerungseinheit gesandt wird, beispielsweise einer Nachricht mit Angaben zum Zustand des Feldgeräts oder des Prüfgeräts.The information about the pending or started maintenance can be transmitted in a separate message to the control unit. Alternatively or additionally, the information of a message can be added, which is also in the Normally sent to the control unit, such as a message with information on the state of the field device or the tester.
Gemäß einem Beispiel, welches keine Ausführungsform der vorliegenden Erfindung ist, ist das mindestens eine Prüfgerät eingerichtet, die Steuerungseinheit mit einer Meldung über die Wartung zu informieren und dabei einen Kommunikationskanal zu verwenden, der separat zwischen Prüfgerät und Steuerungeinheit besteht oder aufgebaut wird. Dieser externe Kommunikationskanal kann unabhängig von einem Kommunikationsmedium zwischen Feldgerät und Steuerungseinheit sein.According to an example, which is not an embodiment of the present invention, the at least one test device is arranged to inform the control unit with a message about the maintenance, thereby using a communication channel that exists or is set up separately between tester and control unit. This external communication channel can be independent of a communication medium between field device and control unit.
Aus einer Vielzahl bekannter geeigneter derartiger externer Kommunikationskanäle seien ein bestehendes WLAN-Netz oder ein Mobilfunknetz oder auch eine drahtgebundene Verbindung zur Steuerungseinheit beispielhaft genannt.From a variety of known suitable such external communication channels an existing wireless network or a mobile network or a wired connection to the control unit are exemplified.
Zum Beispiel bei einer Prozesseinrichtung, in der die Feldgeräte und die Steuerungseinheit(en) über einen Feldbus kommunizieren, kann mit solch einem externen Kommunikationskanal auf praktikable Weise eine direkte, störungsfreie Kommunikation zwischen Prüfgerät und Steuerungseinheit gewährleistet werden.For example, in a process device in which the field devices and the control unit (s) communicate via a field bus, a direct, trouble-free communication between the test device and the control unit can be ensured in a practical manner with such an external communication channel.
Erfindungsgemäß ist das Prüfgerät eingerichtet, die Steuerungseinheit mit einer Meldung unter Verwendung eines Kommunikationskanals über die Wartung zu informieren, der über das Feldgerät verläuft.According to the invention, the test apparatus is set up to inform the control unit about the maintenance by means of a message using a communication channel which runs via the field device.
Das Feldgerät kann dabei eingerichtet sein, die Meldung oder Teile der Meldung unverändert an die Steuerungseinheit weiterzuleiten. Beispielsweise kann das Feldgerät die Meldung in Form eines IP-Pakets vom Prüfgerät erhalten und an die Steuerungseinheit weiterleiten, ohne den Inhalt der Meldung zu interpretieren.The field device can be set up to forward the message or parts of the message to the control unit unchanged. For example, the field device may receive the message in the form of an IP packet from the tester and forward it to the control unit without interpreting the contents of the message.
Alternativ oder zusätzlich kann das Feldgerät eingerichtet sein, bei der eingehenden Meldung eine Umsetzung von einer ersten Kommunikationstechnik (die zwischen Prüfgerät und Feldgerät eingesetzt wird) auf eine andere Kommunikationstechnik (die zwischen Feldgerät und Steuerungseinheit verwendet wird) durchzuführen. Beispielsweise kann die erste Kommunikationstechnik eine drahtlose Near-Field-Communication oder eine Bluetooth-Übertragung sein und die andere Kommunikationstechnik eine drahtgebundene Übertragung über einen Feldbus; andere Kombinationen von Kommunikationstechniken sind alternativ ebenfalls möglich. Die Umsetzung kann eine Protokollübersetzung umfassen, für die das Feldgerät eine Datenkonvertierung an der Meldung durchführt. Das Feldgerät kann dazu eine Gatewayfunktionalität aufweisen.Alternatively or additionally, the field device can be set up, in the case of the incoming message, a conversion from a first communication technology (which is used between test device and field device) to another communication technology (which is used between field device and control unit). perform. For example, the first communication technique may be a wireless near-field communication or a Bluetooth transmission, and the other communication technique may be a wired transmission over a field bus; other combinations of communication techniques are alternatively possible as well. The implementation may include a protocol translation for which the field device performs a data conversion on the message. The field device may have a gateway functionality for this purpose.
Das Prüfgerät weist Mittel auf, die dazu dienen, eine Steuerungseinheit einer Prozesseinrichtung zu informieren, wenn das Prüfgerät ein Feldgerät wartet oder zu warten im Begriff steht. Die Mittel können gemäß einem Beispiel, das keine Ausführungsform der vorliegenden Erfindung ist dabei geeignet sein, eine Meldung über die Wartung vom Prüfgerät an mindestens eine Steuerungseinheit zu senden. Erfindungsgemäß sind die Mittel geeignet, das zu wartende Feldgerät zu veranlassen, selbst eine solche Meldung an die mindestens eine Steuerungseinheit zu senden.The testing device has means which serve to inform a control unit of a process device when the test device is waiting or waiting for a field device. The means according to an example which is not an embodiment of the present invention may be adapted to send a maintenance message from the tester to at least one control unit. According to the invention, the means are suitable for causing the field device to be serviced to send such a message to the at least one control unit.
Das Prüfgerät hat somit den Vorteil, dass es mit einer Prozesseinrichtung so interagieren kann, dass letztere eine Wartung eines ihrer Feldgeräte automatisch erkennen und angemessen reagieren kann.The tester thus has the advantage that it can interact with a process device so that the latter can automatically detect maintenance of one of its field devices and react appropriately.
Das Feldgerät weist Mittel auf, die eine einseitige oder zweiseitige Interaktion mit einem Prüfgerät erlauben, wenn das Prüfgerät eine Wartung des Feldgeräts ansetzt oder bereits durchführt. Diese Mittel können dazu dienen, Nachrichtensignale automatisch dann zu erfassen, wenn das Prüfgerät solche Nachrichtensignale an das Feldgerät sendet.The field device has means that allow one-way or two-way interaction with a test device when the test device attaches or already performs a maintenance of the field device. These means can be used to automatically detect message signals when the tester sends such message signals to the field device.
Gemäß einem Beispiel, das keine Ausführungsform der Erfindung ist, können die Mittel zum Erfassen eines mechanischen Kontakts mit dem Prüfgerät dienen. Beispielsweise können ein oder mehrere Schalter im Feldgerät vorhanden sein, die ein aufsetzendes Prüfgerät betätigt, oder die Mittel können ein oder mehrere berührungsempfindliche Sensoren oder aktive Abstandssensoren sein oder solche Sensoren umfassen. Ein derartiger aktiver Abstandssensor kann beispielsweise eingerichtet sein, mittels von ihm selbst ausgestrahlter Infrarot- und/oder Schallwellen ein in der Nähe (z.B. in einem Abstand kleiner als etwa 1 cm oder kleiner als etwa 0,5cm) befindliches Prüfgerät zu erkennen.According to an example which is not an embodiment of the invention, the means may be for detecting mechanical contact with the tester. For example, one or more switches may be present in the field device that actuates an attaching tester, or the means may be one or more touch-sensitive sensors or active proximity sensors, or may include such sensors. Such an active distance sensor can be set up, for example, by means of infrared and / or radiated by itself Sound waves near a tester (eg at a distance less than about 1 cm or less than about 0.5 cm) located.
Alternativ oder zusätzlich können die Mittel geeignet sein, ein Kraftfeld wie beispielsweise ein Magnetfeld dann zu erfassen, wenn das Prüfgerät ein solches Kraftfeld erzeugt. Schließlich können die Mittel zusätzlich oder alternativ dem Feldgerät ermöglichen, mindestens ein Identifikationsmerkmal wie beispielsweise einen Token an das Prüfgerät zu senden.Alternatively or additionally, the means may be adapted to detect a force field such as a magnetic field when the test device generates such a force field. Finally, the means may additionally or alternatively enable the field device to send at least one identification feature, such as a token, to the testing device.
Das Feldgerät weist also den Vorteil auf, dass es, wenn es in einer Prozesseinrichtung eingebunden ist, in Kombination mit einem geeigneten Prüfgerät ermöglicht, dass eine Wartung automatisch erkannt und die Information darüber an die Steuerungseinheit weitergeleitet wird. So wird dieser eine entsprechend angemessene Reaktion auf Auslösesignale ermöglicht.The field device thus has the advantage that, if it is integrated in a process device, in combination with a suitable test device, it allows maintenance to be automatically detected and the information about it to be forwarded to the control unit. This allows for a correspondingly adequate response to trip signals.
