Description
Die Erfindung betrifft eine Einrichtung zur Energieversorgung von Feldgeräten in verfahrenstechnischen Anlagen nach dem Oberbegriff des Schutzanspruchs 1.The invention relates to a device for supplying energy to field devices in process engineering plants according to the preamble of claim 1.
Bekannte Feldgeräte sind mittels einer mehradrigen Verbindungsleitung mit einer zentralen Einrichtung verbunden, wobei jedes Feldgerät über die Verbindungsleitung mit elektrischer Energie zu seinem Betrieb versorgt wird und mit der zentralen Einrichtung Daten austauscht.Known field devices are connected to a central facility by means of a multi-core connecting cable, whereby each field device is supplied with electrical energy for its operation via the connecting cable and exchanges data with the central facility.
Komplexe verfahrenstechnische Anlagen sind mit einer Vielzahl derartiger Feldgeräte ausgestattet. Dabei ist das Netz der Verbindungsleitungen für den Betreiber der Anlage ein erheblicher Kostenfaktor und darüber hinaus insbesondere im Zuge von Bauarbeiten Störungen durch Leitungsunterbrechungen ausgesetzt. Bei einer Leitungsunterbrechung ist das angeschlossene Feldgerät sowohl von dem Datenaustausch mit der zentralen Einrichtung abgeschnitten als auch von der Energieversorgung zu seinem Betrieb.Complex process engineering plants are equipped with a large number of such field devices. The network of connecting lines represents a significant cost factor for the plant operator and is also subject to disruptions due to line interruptions, particularly during construction work. If a line is interrupted, the connected field device is cut off from both the exchange of data with the central facility and from the power supply for its operation.
Zwar gelingt es, mit Hilfe von drahtlosen Kommunikationseinrichtungen, die jedem Feldgerät und der zentralen Einrichtung zugeordnet werden, den Datenaustausch unabhängig vom Netz der Verbindungsleitungen aufrechtzuerhalten, soweit die Feldgeräte weiterhin mit Energie versorgt sind. Jedoch sind die Feldgeräte bei Leitungsunterbrechungen von der Energiequelle getrennt.It is possible to maintain data exchange independently of the network of connecting cables using wireless communication devices that are assigned to each field device and the central device, as long as the field devices continue to be supplied with energy. However, the field devices are disconnected from the energy source if the lines are interrupted.

Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile des Standes der Technik zu überwinden und Mittel anzugeben, die eine vom Netz der Verbindungsleitungen unabhängige Energieversorgung der Feldgeräte gestattet.The invention is therefore based on the object of overcoming the disadvantages of the prior art and of providing means which allow a power supply of the field devices independent of the network of connecting lines.
Erfindungsgemäß wird diese Aufgabe mit den Mitteln des Schutzanspruchs 1 gelöst. Eine vorteilhafte Ausgestaltung der Erfindung ist in dem rückbezogenen Anspruch genannt.According to the invention, this object is achieved by the means of claim 1. An advantageous embodiment of the invention is mentioned in the dependent claim.
Die Erfindung geht davon aus, dass der Leistungsbedarf zur Versorgung derzeitiger Feldgeräte durch zunehmende Integration auf einige wenige Milliwatt reduziert ist.The invention assumes that the power requirement for supplying current field devices is reduced to a few milliwatts through increasing integration.
Erfindungsgemäß ist eine zentrale netzgespeiste Sendeeinrichtung hochfrequenter elektromagnetischer Strahlung vorgesehen und das Feldgerät mit einer Empfangseinrichtung für die hochfrequente elektromagnetische Strahlung ausgestattet, mit der die empfangene Strahlungsenergie in einen elektrischen Strom umgesetzt wird.According to the invention, a central mains-powered transmitting device for high-frequency electromagnetic radiation is provided and the field device is equipped with a receiving device for the high-frequency electromagnetic radiation, with which the received radiation energy is converted into an electrical current.
Nach einem weiteren Merkmal der Erfindung ist das Feldgerät mit einem Speicher elektrischer Energie ausgestattet.According to a further feature of the invention, the field device is equipped with a storage device for electrical energy.
Bei diskontinuierlicher Verfügbarkeit der hochfrequenten elektromagnetischen Strahlung wird die diskontinuierlich erzeugte elektrische Energie zur Versorgung des Feldgeräts während der Unterbrechung des Zuflusses der hochfrequenten elektromagnetischen Strahlung im Feldgerät gespeichert. Damit ist die kontinuierliche unterbrechungsfreie Versorgung des Feldgeräts mit elektrischer Energie zu seinem Betrieb gewährleistet.If the high-frequency electromagnetic radiation is intermittently available, the intermittently generated electrical energy is stored in the field device to supply the field device during the interruption of the flow of high-frequency electromagnetic radiation. This ensures the continuous, uninterrupted supply of the field device with electrical energy for its operation.
Vorteilhafterweise kommt die Energieversorgung des Feldgeräts ohne elektrische Verbindungsleitungen von und zu einer zentralen Quelle elektrischer Energie aus. Die Verfügbarkeit der Feldgeräts ist damit unabhängig von Störungen durch Leitungsunterbrechungen. Darüber hinaus ist der erhebliche materielle Aufwand für ein Netz von elektrischen Verbindungsleitungen und dessen Wartung und Pflege insgesamt verzichtbar.Advantageously, the power supply of the field device does not require electrical connecting cables to and from a central source of electrical energy. The availability of the field device is therefore independent of disruptions caused by line interruptions. In addition, the considerable material expenditure for a network of electrical connecting cables and its maintenance and care is completely dispensable.
