Definitions

  • Industrial plants also called automation systems, are used for the automated production of products and for the automated execution of processes. Depending on the requirements of the system, they are composed of many small and large components. In these components, a variety of functionalities, such as measuring, controlling, controlling, the operation of the components via interfaces and the communication between the components and the interfaces are realized.
  • the components may be individual machines, conveyor units or entire manufacturing cells with internal structure. There are also dependencies between these components, which, for example, dictate that a particular component can not be turned on or off until one or more other components are in a defined state.
  • the raising or lowering of such a complex system is a process that extends for a long period of time as well as done manually, because the ⁇ game of components is too complex to program a sequence sequence explicitly.

It enables the compo ⁇ nents of a plant, the possible states and building state transitions each plant component and to define the logical interdependencies and save. Under logical dependencies is understood in the following that a switching operation of at least one conditioning component further requires to ⁇ stands of other system components to control arranged a plant or a plant part. For the states and state transitions, further information has been created which will later be helpful or even necessary for switching. This information includes z. B. the power ⁇ recordings in the individual component states, as well as the times and the load curves for each state transitions in the components.
  • the Energyschaltcont ⁇ roller By knowing the dependencies between the components of the system, it is (the Energyschaltcont ⁇ roller) of the device possible to switch each component in its various states.

  • FIG. 9 shows an exemplary system with a plurality of energy switch controllers.
  • the power switching controller contains the following functions in its interface upwards (ie to higher-level systems):

  • an energy state model 332 is shown by way of example. This is already included in the component.
  • FIG. 3 shows a prior art system analogous to FIG. 2, which represents support / implementation of the prior art disconnection logic. This is accommodated in the respective plant controllers or in the controllers of the subsystems, on / off switching.
  • FIG. 4 shows an exemplary plant 12 and state model 13. This is a test plant in which small parts are filled into bottles, the bottles are checked for correct content and then emptied again.
  • the state is then changed: only in the case of state changes in the model is it necessary to switch in the real plant.

  • the STANDBY states are characterized by a lower power consumption than in the operating state.
  • Figure 7 is provides for the exemplary system a possible Ag ⁇ gregierung of components of the system into subsystems ones shown,. There are multi-level hierarchies possible depen ⁇ pendencies can be inherited through multiple levels.
  • FIG. 8 shows the plant from FIG. 7 with state models according to the invention, in particular for aggregate components.
  • the power switching controller In order for the power switching controller to always have an overview of the dependencies of the components of a system in order to be able to switch them in a coordinated manner, it is necessary for it to be sufficiently high in the hierarchy of the components. However, it is possible to equip parts of a plant (eg a machine or a line) that are relatively self-sufficient - ie have only little dependency on other components outside - with their own energy switching controller, which then in turn via its own interface can be used by a higher power ⁇ switching controller. As a result, a hierarchical staggering of energy switching controllers is also possible, see FIG. 9.

Abstract

Dispositif de commande d'une installation ou d'une partie d'une installation, constituées de composants d'installation. La commande repose sur l'utilisation d'un modèle de structure de l'installation, ainsi que sur des modèles d'état des composants constituant l'installation. Les modèles utilisés contiennent également des informations sur des états possibles auxquels les composants de l'installation peuvent passer, et sur la consommation d'énergie de chaque composant dans son état du moment, ainsi que d'autres informations sur des relations logiques entre des composants individuels dans leur état énergétique du moment. Par relations logiques, il faut entendre dans ce qui suit le fait qu'un processus de connexion d'au moins un composant d'installation présuppose d'autres états d'autres composants de l'installation pour commander une installation ou une partie d'installation de manière ordonnée. La connaissance des relations entre les composants de l'installation permet au dispositif (dispositif de commande de connexion d'énergie, ESC) de connecter chaque composant dans ses différents états. L'installation peut ainsi être connectée dans des états globaux prédéfinis (se composant de combinaisons des états des composants). La présente invention permet non seulement la connexion ou la déconnexion automatique de l'installation, mais aussi la commutation vers des états d'économie d'énergie définis en fonctionnement non productif, à savoir les états dits de veille, ainsi que vers des états d'économie d'énergie en fonctionnement productif, par ex. un fonctionnement à charge partielle.
