Definitions

  • the invention relates to a method for controlling and / or monitoring a compressor system comprising a plurality of components, namely one or more compressors and one or more peripheral devices, and a control / monitoring unit, wherein the compressors and peripheral devices are arranged or interconnected in a specific configuration, according to the features of claim 1 and a compressor system according to claim 16.
  • Compressor systems such as from document DE 10 2011 079 732 A1 are known, represent a system of a variety of compressors and peripheral devices of various types, which are coupled together via an air duct network and, when using heat recovery systems, via a water pipeline network.
  • compressor systems are designed individually for the local conditions.
  • a general structure for compressor systems does not exist. Therefore, the behavior of a concrete compressor system can only be analyzed and evaluated to a limited extent without knowledge of the structure of the compressor system.
  • control / monitoring unit may also be the task of the control / monitoring unit to collect measured values accumulating in the compressor system and store them as time courses or timestamps in order to evaluate these measured values later in the control / monitoring unit or also in other technical systems. It can be particularly interesting if a large number of different measured values are collected from within or also outside the compressor system, in order to be able to create analyzes from this and to draw conclusions in the following, in particular by forming correlations, etc.
  • a central idea of the present invention is based on the following guiding principle: In order to be able to further process the measured values which are relevant for the compressor installation in different questions, it is essential that the meaning of the measured values is defined and known at the latest at the time of evaluation of the measured values. Advantageous In this case, it may also be the case that the measured values of defined and known significance are prepared in advance, during or as a result of the method in such a way that they can be further processed in the control / monitoring unit but also in other technical systems.
  • the preparation can be understood as measured value standardization.
  • the standardization of measured values also has the advantage that measured values from various compressor systems can be processed without compressor-plant-specific adaptations of the routines intended for measured value processing.
  • the measured value standardization takes place in that context information is assigned to the measured value itself, so that the context of the measured value is defined at the latest at the time of the evaluation of the measured value.
  • the context of the measurement may directly or indirectly define the location of the measurement acquisition and / or the medium (e.g., oil, compressed air, ambient air, cooling water, etc.) to which the measurement relates.
  • the medium e.g., oil, compressed air, ambient air, cooling water, etc.
  • Indirect context information can in exceptional cases also take place via a name definition, namely when it is sufficiently unambiguous.
  • a name definition is only a very soft definition of the meaning of a metric, since it is very likely that the name definition will be differently applied or interpreted by different people, so that a unique context for the metric over a name definition will not necessarily be guaranteed.
  • a measured value may have several not necessarily contradictory meanings that may change compressor specific or component specific.
  • Preferred context information defines the location of the measurement directly, for example, using a model of the component or the compressor system.
  • a control, monitoring, diagnostic or evaluation routine should generally be understood as meaning different control tasks, monitoring tasks, diagnostic tasks or evaluation tasks.

  • an R & I scheme in the sense of the present invention can be abstracted from the basic interactions in a viewing direction / from a domain and thus does not have to include all the details of a possibly otherwise common P & I scheme.
  • P & ID scheme instead of the term P & ID scheme, it is also possible to understand a graphical representation of the functional relationships in a specific perspective / in a specific domain, such as, for example, a graphical representation of compressed air technical correlations, a graphic representation of the heat recovery related effects. It is insofar a flow chart that reflects the flow of energy and / or resources and / or compressed air between the individual compressors and the individual peripherals or between the individual elements of a component.
  • the measured value acquisition step may comprise the metrological direct acquisition of a measured value and / or the recourse to already existing, in particular stored, measured values.
  • measured values which are already available, on the one hand are measured values from the directly representational compressor system or external measured values.
  • External readings may be comparative data from other compressor equipment or environmental data, such as humidity, air temperature of outdoor or ambient air.
  • the measured value acquisition step comprises, in addition to the direct measurement-related detection of the measured values, also the storage of these measured values in an assigned database, which can be implemented in one or more components, in the compressor system or externally.
  • the standardization of the measured value by assigning a context information specifically comprises the unique assignment of the location of a measured value acquisition and / or the medium to which the measured value refers (eg oil, compressed air, ambient air, cooling water, etc.) to a measured value within an assignment step according to the invention.

  • the location of the measured value detection is defined by one or more output models of the specific compressor system or comparable compressor systems and / or one or more output models of the specific components or comparable components.
  • These output models can be defined for example by the aforementioned R & I schemes of the compressor system or the aforementioned R & I schemes of the corresponding components.

  • the superordinate state of the compressor system and / or individual components at the time of data acquisition can also be assigned to the respective measured value (s). This ensures that non-differentiated measured values of a compressor in the startup behavior are compared with measured values of a compressor in the stable operating state, without these different boundary conditions also being taken into account in such a comparison.
  • the superordinate state of the compressor system can also be taken into account, for example, by assigning one or more other measured values of the compressor system at this time as additional context information to the one or more measured values from which the state of the compressor system or a partial state of the compressor system can be derived.

    sachant que les compresseurs (11, 12, 13) et appareils périphériques (14 à 21) sont disposés ou connectés dans une configuration prédéterminée, et
    sachant que l'unité de cammande/surveillance (22) présente une unité d'acquisition de valeurs de mesure (25) ou interagit avec une unité d'acquisition de valeurs de mesure (25) qui est constituée pour l'acquisition de valeurs de mesure au sein de l'installation de compresseurs ou des composants, caractérisée en ce que l'unité de commande/surveillance (22) comprend en outre une unité d'affectation (26) ou interagit avec une unité d'affectation (26) qui est constituée pour affecter respectivement une information contextuelle aux valeurs de mesure acquises afin de standardiser les valeurs de mesure,
    - sachant qu'un modèle de départ sous forme d'un schéma R&I ou des informations contextuelles plus faibles codant l'endroit de l'acquisition de valeurs de mesure servent de base pour l'information contextuelle
    - et sachant que l'unité de commande/surveillance (22) comprend une interface (27) pour transmettre les valeurs de mesure standardisées par l'information contextuelle ou les utiliser elle-même dans des routines de commande, de surveillance, de diagnostic ou d'évaluation consécutives.
