Dazu wird vorgeschlagen, przessual in der verfahrenstechnischen Anlage vorhandene, nicht-elektrische Primärenergie in elektrische Energie umzusetzen und das Feldgerät mit dieser elektrischen Energie zu versorgen.The invention relates to a method for supplying energy to field devices with a wireless communication interface in a process engineering system. For this purpose, it is proposed to convert non-electrical primary energy present in the process engineering system into electrical energy and to supply the field device with this electrical energy.
Description
Die Erfindung betrifft ein Verfahren zur Energieversorgung von Feldgeräten in verfahrenstechnischen Anlagen gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a method for supplying energy to field devices in process plants according to the features of 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 by means of a multi-core connecting line with a central device connected, each field device via the connecting line is supplied with electrical energy for its operation and with the central one Facility exchanges data.
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 systems are with a variety of such field devices fitted. The network of connecting lines is for the operator of the system a considerable cost factor and moreover especially in the course of Construction work exposed to interruptions due to line breaks. At a Line interruption is the connected field device from both Data exchange with the central facility cut off as well from the Energy supply to 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 with the help of wireless communication facilities that everyone Field device and the central device are assigned to the data exchange independent of the network of connecting lines, insofar as the Field devices continue to be supplied with energy. However, the field devices are at Line interruptions separated from the energy source.
Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile des Standes der Technik zu überwinden und die Feldgeräte unabhängig vom Netz der Verbindungsleitungen mit Energie zu ihren Betrieb zu versorgen.The invention is therefore based on the object, the disadvantages of the prior art Technology to overcome and the field devices independent of the network of To supply connecting lines with energy for their operation.
Die Erfindung geht davon aus, dass der Leistungsbedarf zur Versorgung derzeitiger Feldgeräte durch zunehmende Integration auf einige wenige Müllwatt reduziert ist.The invention assumes that the power requirement to supply current Field devices is reduced to a few garbage wastes due to increasing integration.
Erfindungsgemäß ist vorgesehen, prozessual in der verfahrenstechnischen Anlage vorhandene, nicht-elektrische Primärenergie in elektrische Energie umzusetzen und das Feldgerät mit dieser elektrischen Energie zu versorgen.According to the invention, there is provision in terms of process in the process plant convert existing, non-electrical primary energy into electrical energy and to supply the field device with this electrical energy.
Die Erfindung macht sich zu Nutze, dass in Abhängigkeit von der Art der verfahrenstechnischen Anlage mindestens eine Quelle nicht-elektrischer Primärenergie dauerhaft zur Verfügung steht. Dabei wird unter dauerhafter Verfügbarkeit auch diskontinuierliche aber periodische Verfügbarkeit verstanden.The invention takes advantage of the fact that, depending on the type of process plant at least one source of non-electrical primary energy is permanently available. It is also under permanent availability discontinuous but periodic availability understood.
Bei diskontinuierlicher Verfügbarkeit der nicht-elektrischen Primärenergie wird die diskontinuierlich erzeugte elektrische Energie zur Versorgung des Feldgeräts während der Unterbrechung des Zuflusses der nicht-elektrischen Primärenergie im Feldgerät gespeichert. Damit ist die kontinuierliche unterbrechungsfreie Versorgung des Feldgeräts mit elektrischer Energie zu seinem Betrieb gewährleistet.In the case of discontinuous availability of the non-electrical primary energy, the discontinuously generated electrical energy for supplying the field device during the interruption of the inflow of non-electrical primary energy in the field device saved. This means that the Field device with electrical energy ensures 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.The energy supply of the field device advantageously comes without electrical Connection lines from and to a central source of electrical energy. The The availability of the field devices is therefore independent of interference Line interruptions. In addition, the considerable material expense for one Network of electrical connecting lines and its maintenance and care altogether dispensable.
