Description

  • The invention relates to a method for diagnosing at least one automation system with at least one pneumatic actuator and / or at least one electrical actuator, in particular at least one valve device, comprising the steps of: detecting system operating data, in particular sensor data and / or usage data, at the operating location of the automation system and providing Diagnostic data, in particular with regard to a lifetime prognosis, based on the plant operating data.
  • The automation system is used, for example, in industrial automation, process automation and / or factory automation. In the automation system, the flow of a fluid, in particular of a process fluid, is expediently controlled with the aid of the valve device.
  • It is known to equip one or more components of an automation system with a local diagnostic function, which can make a prognosis regarding their service life on the basis of recorded system operating data, for example sensor data. The diagnostic function is provided, for example, by means of a model integrated in the components and can be used with the aid of a customer application.
  • An object of the invention is to improve the aforementioned method so that more accurate diagnostic data can be provided.
  • The object is solved by the features specified in claim 1.
  • According to the invention, a method for diagnosing at least one automation system is provided, wherein the automation system comprises at least one pneumatic actuator and / or at least one electrical actuator, in particular at least one valve device. The method comprises the steps of acquiring plant operating data, in particular sensor data and / or usage data, at the automation plant operating site and providing diagnostic aid data, in particular life prediction data, energy forecasting data, maintenance prediction data and / or operating parameter recommendation data, in a database in a diagnostic auxiliary data server remote from the operating site. The diagnostic auxiliary data includes test operational data and / or simulation data. The test operation data is based on performing a test operation of at least one test component that does not belong to the automation system. The simulation data is based on a simulation of a plant component of the automation plant.
  • The method further comprises the steps of: merging the plant operating data and the diagnostic auxiliary data via a communication platform, in particular a wide area network, preferably the Internet, and / or a cloud, and providing diagnostic data, in particular with regard to a life prediction, an energy consumption forecast, a maintenance forecast and / or a Operating parameter recommendation, based on plant operating data and diagnostic auxiliary data.
  • According to the invention, the diagnostic data are thus not only provided on the basis of plant operating data, but also in the provision of the diagnostic data also diagnostic auxiliary data are taken into account, which are provided by a remote diagnostic auxiliary data server and based on test operating data and / or simulation data. In this way, the diagnostic data can be created using a much larger database, which can improve the accuracy of the information contained in the diagnostic data.
  • The diagnostic auxiliary data server can be, for example, a server of the manufacturer of the automation system and / or specific components of the automation system. Consequently, diagnostics auxiliary data can be provided in the diagnostic auxiliary data server, in particular directly from the manufacturer, which can be based, for example, on extensive test operations and / or extensive simulations by the manufacturer and, in particular, can also be continuously updated. By means of the method according to the invention, these data can then be taken into account for the provision of the diagnostic data in addition to the locally recorded system operating data, thus leading to an overall more accurate result.
  • The plant operating data acquired at the operating site of the automation system are, for example, usage data, that is, for example, a number of actuations, strokes or switching cycles of an actuator, a temperature, a pressure, and / or a current profile. Based on this data, diagnostic data, such as the life expectancy and / or energy consumption prognosis, may be provided. If, in accordance with the invention, the diagnosis aid data are additionally used by the diagnostic auxiliary data server in the provision of the diagnostic data, then the accuracy of the diagnostic data, for example the accuracy of the mentioned prognosis of the service life and / or the energy consumption, can be improved.
  • By way of example, the diagnostic auxiliary data are parameters with which the diagnostic data-that is, in particular a prognosis with regard to the service life and / or the energy consumption-can be made on the basis of the plant operating data. These diagnostic diagnostic data can be updated continuously as they are based on test operation and / or simulation, so that the use of these diagnostic diagnostic data when generating the diagnostic data ensures the most accurate possible result, taking the latest findings into account.
  • Advantageous developments are the subject of the dependent claims.
  • According to one embodiment, the method comprises the step: performing the test operation, in particular a long-term test operation, preferably over several months or years, the test component and providing the diagnostic auxiliary data based on the test operation performed.
  • Expediently, the test operation is carried out in parallel, ie in particular at the same time, for the operation of the automation system. The diagnostic aid data obtained in this way can be repeated, preferably continuously, provided and / or updated. In this way it can be ensured that the diagnostic data are always based on the latest test findings with regard to the automation system or the components used therein.
  • According to a further embodiment, the diagnostic data is provided by a diagnostic module, in particular by a software component, which is provided in at least one controller and / or a gateway of the automation system and / or an external server not belonging to the automation system, in particular the diagnostic auxiliary data server.
  • The diagnostic data can thus be provided directly on one or more components of the automation system. Alternatively or additionally, the diagnostic data can also be provided on an external server, and then transmitted, for example, to the operating location of the automation system.
  • According to one embodiment, the diagnostic module is configured and / or is designed such that it can not influence the control of actuators of the automation system.
  • For example, the diagnostic module is executed in its own, in particular an encapsulated runtime environment, so that no influence on the control of the actuators of the automation system can be taken by the diagnostic module. In this way it can be prevented, in particular, that an unauthorized external intervention, for example via the communication platform, on the diagnostic module can influence the control of the automation system.
  • According to another embodiment, the diagnostic auxiliary data includes a diagnostic model, and the diagnostic data is provided by applying the diagnostic model to the plant operating data.
  • The diagnostic model is, for example, a mathematical model into which the plant operating data can be used so that as a result the diagnostic data are obtained. The diagnostic model, for example, based on the results of the test operation and / or the simulation can be continuously developed and thus ensure the highest possible accuracy of the diagnostic data.
  • According to a further embodiment, the automation system has a plurality of components, each of which is assigned an identifier, wherein the plant operating data are detected in association with the identifiers and the provision of the diagnostic auxiliary data based on the identifiers.
  • By way of example, separate plant operating data and diagnostic auxiliary data for each component can be provided by means of the identifier, so that finally also for each of these components own diagnostic data - for example, an own life prognosis and / or a separate energy consumption diagnosis - can be provided.
  • According to a further embodiment, the plant operating data comprise operating parameters, in particular a temperature, a humidity, an air pressure and / or an air composition. Expediently, on the basis of the operating parameters, a selection of the diagnostic auxiliary data on the basis of which the diagnostic data are provided is carried out.
  • For example, different diagnostic auxiliary data may be provided on the diagnostic auxiliary data server for different operating parameters or operating parameter ranges. Depending on the operating parameters contained in the plant operating data, appropriate diagnostic auxiliary data can then be selected, on the basis of which in turn the diagnostic data is provided. For example, for a first temperature range, first diagnostic auxiliary data may be provided and for a second Temperature range second diagnostic auxiliary data can be provided. If the operating parameters contained in the plant operating data now indicate that the automation plant is operated in the first temperature range, the first diagnostic auxiliary data (and not the second diagnostic auxiliary data) can be used in the provision of the diagnostic data.
  • Thus, when providing the diagnostic data, the operating parameters actually prevailing in the automation system to be diagnosed can be discussed.
  • In accordance with a further embodiment, the method is used to diagnose at least two automation systems. In this case, further plant operating data of a further automation system are recorded. The further automation system is arranged away from the operating location of the automation system. Diagnostic helper data is provided in the external database, and the other plant operational data and diagnostic helper data are merged through the communication platform. Based on the further plant operating data and the diagnostic auxiliary data, further diagnostic data are provided.
  • Consequently, one and the same diagnostic auxiliary data server can be used for the diagnosis of multiple automation plants located at different operating locations.
  • The invention further relates to a system comprising at least one automation system with at least one pneumatic actuator and / or at least one electrical actuator, in particular at least one valve device. The automation system is designed to record plant operating data, in particular sensor data and / or usage data, at the operating location of the automation system. The system further includes a diagnostic help data server remotely located from the operating site and having a database providing diagnostic utility data, in particular life prediction data, energy usage prediction data, maintenance prediction data, and / or operating parameter recommendation data.

The test operating data is based on the execution of a test operation of at least one test component not belonging to the automation system. The simulation data is based on a simulation of a plant component of the automation plant.
