Zur Übertragung der Wärmeenergie zwischen einem Fernwärmeverteilnetz und dem Heizkreislauf in den einzelnen Gebäuden werden Hausstationen (Anschlussstellen) verwendet, in denen der Energieaustausch zwischen dem Heizkreislauf und dem Fernwärmekreislauf über Wärmetauscher erfolgt. Die Steuerung dieses Prozesses erfolgt über Fernheizregler, die mit einer Regelelektronik versehen ist. Diese Regelelektronik kann von einer Zentraleinheit gesteuert und abgefragt werden.For the transmission of heat energy between a district heating distribution network and the Heating circuit in the individual buildings become house stations (connection points) used in which the energy exchange between the heating circuit and the District heating circuit via heat exchanger takes place.

Die Rohre eines Fernwärmeverteilnetzes sind regelmäßig mit Messadern und/oder Messelementen versehen, deren Messwerte von einer Sensorelektronik erfasst werden. Dabei werden die Messadern zu größeren Überwachungsabschnitten zusammengeschaltet und von einem Dauerüberwachungsgerät überwacht. Bei größeren Netzen werden zentralisierte Systeme verwendet, die aus einem Zentralgerät und örtlich verteilten Messgeräten bestehen, die jeweils bestimmte Überwachungsabschnitte auf Feuchtigkeit überwachen und eine Lokalisierung der Schadensstelle ermöglichen. Die Messwertausgabe, die Meldeausgabe sowie die Parametrierung der Einzelgeräte erfolgt von einem Zentralgerät aus.

These too Central devices are usually with display devices for the graphical representation of Asset status and the incoming messages equipped.

Der Erfindung liegt die Aufgabe zugrunde, ein Überwachungssystem für ein mit einer Reglerelektronik versehenes Fernwärmeverteilnetz zu schaffen, das bei Verzicht auf eine gesondertes Übertragungssystem für die Messwerte der Sensorelektroniken eine einfache, genaue Lokalisierung einer Schadensstelle ermöglicht.The invention has for its object to provide a monitoring system for a with a To provide regulator electronics provided district heating distribution network, which waives one separate transmission system for the measured values of the sensor electronics a simple, accurate localization of a damaged area allows.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass jede der Sensorelektroniken zur Ermittlung der von ihnen erfassten Messwerte an eine einer der Anschlussstellen zugehörigen Reglerelektronik eingerichtet ist und die Messadern und/oder Messelementen von der mit ihr verbundenen Sensorelektronik zu einer der jeweiligen Anschlussstelle benachbarten Anschlussstelle verlaufen.According to the invention, this object is achieved in that each of the sensor electronics for Determining the measured values acquired by them at one of the connection points Control electronics is set up and the measurement wires and / or measuring elements of the with her connected sensor electronics to one of the respective connection point adjacent Run junction.

Bei dem von den Sensorelektroniken an die zugehörigen Reglerelektroniken übermittelten Messwerte handelt es sich vorzugsweise um den Isolationswiderstand der Wärmedämmung, andere durch Feuchtigkeit in der Wärmedämmung beeinflusste elektrischen Parameter (Spannungen, Ströme in Amplitude und/oder Signalform), oder den Widerstandswert der Messadem.When transmitted from the sensor electronics to the associated control electronics Measured values are preferably the insulation resistance of the thermal insulation, other electrical parameters influenced by moisture in the thermal insulation (Voltages, currents in amplitude and / or waveform), or the resistance of the Messadem.

Die Messelemente können als Messschleife ausgebildet sein, die durch eine Fühlerader und einer Rückführader gebildet ist.The measuring elements may be formed as a measuring loop, which by a sensor wire and a Rückführader is formed.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert.The invention will be explained below with reference to a drawing.

Das Fernwärmeverteilnetz besteht aus Rohren 18, das zu Anschlussstellen 10 führt. An den Anschlussstellen sind Regler angeordnet, die mit Pumpen und/oder Ventilen versehen sind, die über eine Reglerelektronik 14 gesteuert werden. Diese Reglerelektronik wird von einer Zentraleinheit 12 gesteuert und abgefragt.The district heating distribution network consists of tubes 18, which leads to connection points 10. To the Connection points are arranged regulators, which are provided with pumps and / or valves, which are controlled by a controller electronics 14. This controller electronics is powered by a Central unit 12 controlled and queried.

Das Überwachungssystem weist weiter eine Mehrzahl von Sensorelektroniken 16 auf, die Messwerte der Sensoren 20 erfassen, die aus in das Isolationsmaterial der Rohre 18 des Fernwärmeverteilnetzes eingebrachten Messadern und/oder Messelementen bestehen 20.The monitoring system further comprises a plurality of sensor electronics 16, the Detecting measured values of the sensors 20, which consist of in the insulating material of the tubes 18 of the District heating distribution network introduced Messadern and / or measuring elements exist 20.

Jede der Sensorelektroniken 16 ist zur Übermittlung der von ihnen erfassten Messwerte an die der Anschlussstelle zugehörigen Reglerelektronik 14 eingerichtet. Dabei verlaufen die Sensoren 20 von der mit ihr verbundenen Sensorelektronik 16 zu einer der jeweiligen Anschlussstelle 10 benachbarten Anschlussstelle 10.Each of the sensor electronics 16 is for transmitting the measured values they have acquired to the the connection point associated control electronics 14 set. Here are the run Sensors 20 from the associated sensor electronics 16 to one of the respective Junction 10 adjacent junction 10th

Durch die vorgeschlagene Ausbildung kann mit sehr einfachen Geräten eine vollständige Überwachung auch komplexer Fernwärmenetze durchgeführt werden. Es wird die ohnehin für die Leittechnik (also für die Regler) vorhandene Infrastruktur genutzt: Bei der Abfrage der einzelnen Reglerelektroniken 14 durch die Zentraleinheit 12 erfolgt auch eine Abfrage der Meßwerte der Sensorelektroniken, also z.B. eine Abfrage des Isolationswiderstands des Rohrabschnitts zwischen der abgefragten Reglerelektronik und der benachbarten Anschlussstelle. Da jeweils nur relativ kurze Abschnitte abgefragt werden, ist es auch möglich, differenzierte Aussage über den Netzzustand zu halten, beispielsweise Mehrfachfehler zu erkennen.The proposed training can with very simple devices a complete Monitoring even complex district heating networks are performed. It will be for anyway used the control technology (ie for the controller) existing infrastructure: When querying the individual controller electronics 14 by the central unit 12 is also a query of Measured values of the sensor electronics, e.g. a query of the insulation resistance of the Pipe section between the requested controller electronics and the adjacent Junction. Since only relatively short sections are queried, so it is possible to keep differentiated statement about the network state, for example Recognize multiple errors.

Vorteilhaft ist weiter, dass bei Erweiterungen oder Verdichtungen des Fernwärmeverteilnetzes eine zunehmend differenzierte Aussage möglich ist, da die Anschlussstelle der jeweils abgefragten Reglerelektronik und die benachbarte Anschlussstelle bekannt sind, ist auch die jeweils abgefragte Sensorschleife bekannt.It is also advantageous that in extensions or densifications of District heating distribution network an increasingly differentiated statement is possible because the Connection point of the requested control electronics and the adjacent connection point are known, the respectively polled sensor loop is known.

Zusatzkosten im Bereich des Reglers entstehen praktisch nicht, diese sind bereits heute mit einer ausreichenden Anzahl von Messeingängen versehen, die Sensorelektronik muss an diese Schnittstelle einfach angesteckt werden. Für die Parametrierung stellt die Überwachung lediglich einen zusätzlichen Messwert dar, der in der Zentraleinheit 12 anzuzeigen ist.Additional costs in the area of the controller practically do not arise, these are already today provided a sufficient number of measuring inputs, the sensor electronics must to this Interface can be easily plugged. The monitoring is set for the parameterization merely an additional measured value to be displayed in the central unit 12.
