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 wide variety of functionalities, such as measuring, controlling, regulating, operating 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 built-in system components ie machines, lines or cells, although today support a more or less standardized state model (z. B. OMAC, Or ⁇ ganization for Machine Automation and Control, for packaging machines), but here are neither Energysparzu- stands (z. B. standby) taken into account, nor offer the compo ⁇ nents outside an interface with which it can be connected in such energy-saving states.
  • component suppliers eg mechanical engineers, plant engineers
  • the inventive apparatus for supporting an energy efficient control of a plant or part of a plant consists of a decision logic for Auswer ⁇ processing of information on a structural model of the system to be controlled and at least one state model of the contained in the on ⁇ location components, comprising means for storing associated with the components of actual energetic or functional states and possible state transitions between the individual component states, means for storing dependencies between components included in the plant or plant part, and means for converting the actual states and state transitions associated with the components to the states of the associated one State model and an interface to the controller or to the components of the plant to be controlled, the switching of the components in a new actual state and / or query the state of the component.
  • the possible actual states of the contained components and possible state transitions between the component-specific states as well as the dependencies between the components for calculating a conversion into the structural model are given by the actual states and the state transitions and to a plant control the associated state model for Be ⁇ calculation of the control is made available.
  • the apparatus for controlling a plant energi slaughter it is possible that components of the system, the Moegli ⁇ chen states and state transitions for each component and to define the dependencies ⁇ from each other and store.
  • the device communicates with the system via an interface; ie with the components that belong to the system. These interfaces to the components make it possible to put the respective components in different states.
  • Each component can (off z. B., different standby states, different synchronization states, ready for operation ⁇ riding, operation enable) to several different stands ⁇ possess.
  • This information includes z. B. the power consumption in states, as well as the times and the load curves for state ⁇ transitions. This information can also be queried via the interface. It is now necessary to parameterize this advantageously standardized interface (eg a future extension of PROFIenergy) of the components (eg machines) in such a way that the following goals can be achieved:
  • the state model includes:
  • At least one state of the components which has a lower energy consumption compared to the operating state.
  • new standby states can be defined, which of course will be a corresponding implementation in the Com- component controller to be called.
  • states of the individual units within the component z. B. devices. Mo ⁇ tor / pump runs half power

  • the configuration tool also allows Anle ⁇ gen information for states and state transitions (eg. As the power consumption in states as well as the times and the load curves for state transitions). A initialization ⁇ insurance run from the tool out to determine the levels is possible.
  • the apparatus for supporting an energy efficient control of a plant or part of a plant has advantageously stored further information about Moegli ⁇ chen actual or model states may take the system components with respect to the energy consumption of the component in this state. More In ⁇ formations can be saved to the state transitions gen that can occur between the possible or actual model states that can take plant components, and
  • the duration of a state transition of egg ⁇ nem first state to a second state and / or the energy consumption of the component during the stand may comprise To ⁇ transition.
  • information about dependencies between the components can be stored, in particular the respective stands to ⁇ in which the components are, in particular logic, temporal or energy dependencies.
  • the interfaces are advantageously formed according to the ProfiEnergy standard, for example with a supplement ge ⁇ suitable for the transmission of control commands for switching the component of a first actual state to a second actual state.
  • Ektiansstool by such Pro is to provide simple and fast new components but also existing ones, with a standardized interface (eg future expan ⁇ tertes Profienergy).

  • Such a tool is relevant for machine and plant builders, who have to run machines, cells and lines in large complex production facilities. In the future it will be required in the tenders that these machines, cells and lines in particular have the standardized interfaces for the call by an energy switching controller. Machine and plant engineers can with the help of such
  • logical dependencies mean that a switching operation of at least one system component contains further states. which presupposes plant components in order to control a plant or a plant part in an orderly manner.
  • This information includes z. B. the power consumption in the individual component states, as well as the times and the load profiles for each Zu ⁇ state transitions in the components.
  • the device By knowing the dependencies between the components of the plant, the device is able to switch each component to its various states. This means that the system can also be switched to predefined overall states (made up of combinations of the states of the components). This is not only the system can be switched on automatic ⁇ table on and off, but it can also defined energy-saving states in non-productive operation, so-called standby states, as well as energy-saving states in production such.
  • the configuration for the energy switching controller can be made by parameterization. This allows the complex logical, temporal and energy-related dependencies in the plant at the various possible

For example, they can be used for an overall overview of the plant and its current status, or it can also be used for calculation in other systems.
  • state models states and state transitions
  • n-dimensional state space By describing the dependencies, the possible paths between overall states of the system, that is to say combinations of the states of the individual components and their dependencies, within this state space are limited to the paths that can be safely reached for the system.
  • the control apparatus allows a plant or Anla ⁇ gent hurry automatically operating states in various operating and fostbe- to switch, both for the system as a whole and for its individual components. Since the power switching controller also has information about the switching times of the individual state transitions, as well as the energy consumption in states and state transitions, it is possible for him to process even complex requests so that the system goes into the most energetically favorable states and thereby varnishge ⁇ is that if necessary, it is also available again.

B. get no more parts delivered. Now the fault management using the Energyschaltcont ⁇ rollers can send these unneeded parts of the system in an energy-saving standby state. Expected to be ensured that the system parts "resurrected" in a ⁇ be certain time, so they can be switched back into production.
  • a load management system 23, or in the future a command response controller with a connection to a smart grid, should be able to switch parts of the system off or into standby states for peak load control.
  • these systems can first be determined by the energy switching controller 1, in which states and with which power consumption the system and its components are currently running. It can also determine which states (productive or non-productive) the individual components can be switched on. With the help of specifications (which of course also take into account the ascertainable from the power switching controller dependencies) can now call on the power switch controller to drive the entire system or parts of it in energy-saving states (productive or between non- ⁇ -productive) load management system.
  • a material handling system knows that due to different speeds and buffers in the plant, or due to redundant plant parts, some parts of the plant are only used intermittently. Since it also knows when and how long these parts of the system will be used or not used, such parts (must of course be modeled as components in the power switching controller) can be switched to the most energetically favorable state by the power switching controller for the time of non-use. Also, such system parts could be in partial operating conditions, eg. As long ⁇ samere products are switched.
