  • Publication number: 20170036154
    Abstract: A method for monitoring a pressurized gas-based cleaning process in a hose filter installation (2): during a cleaning process, a throughflow (Q) of a pressurized-gas flow during a predefinable time period (T) is determined, a throughflow characteristic (V) is determined using the determined throughflow (Q) of the pressurized-gas flow, and the pressurized gas-based cleaning process is monitored using the throughflow characteristic (V), wherein the throughflow characteristic (V) is a pressurized-gas quantity that has flowed in the predefinable time period (T). A monitoring system (40) for a hose filter installation (2) has at least one throughflow sensor (44) for determining a throughflow (Q) of a pressurized-gas flow, and a control unit (42) for controlling a pressurized gas-based cleaning process, wherein the throughflow sensor (44) is a volume flow sensor or a mass flow sensor, and the control unit (42) is set up for carrying out the method.

  • Publication number: 20160378089
    Abstract: A method of creating a logical position sensor for a component of an automation system includes an automation device determining (i) a unique identifier for the component; (ii) a geographical position of the component; and (iii) a logical position of the component within a production process performed by the automation system. The method further includes the automation device creating a logical position sensor for the component. The logical position sensor comprises a sensor interface which provides access to the unique identifier, the geographical position of the component, and the logical position of the component.

  • Publication number: 20160279646
    Abstract: A method for operating a filter system (1) for filtering an exhaust gas (11) of a metallurgical plant (12), which exhaust gas (11) comprises solid particles (10), wherein the filter system (1) has at least one electrode pair (2), to each of which an electrical power and/or an electrical voltage and/or an electrical current can be applied. A system for operating such a filter system includes (1) a plant for filtering an exhaust gas (11) of a metallurgical plant (12). The exhaust gas (11) includes solid particles (10). The metallurgical plant (12) includes such a filter system (1).

  • Publication number: 20160151733
    Abstract: A method for detecting a cleaning process in a plant having filters (1, 31) arranged spatially offset from one another, wherein a first gas (21) having solid particles (20) is conducted in a first flow direction (10) filtered by a respective filter (1, 31). To clean the respective filter (1, 31), a second gas (22) is conducted through the filter (1, 31) opposite the first flow direction (10). Then listen to noise produced in the filtering or other physical phenomena to determine a condition of the filter including if it is being cleaned. To detect a cleaning process in a plant, a respective noise (12) is detected by acoustic sensors (2, 32, 2?, 32?, 42) arranged spatially offset from one another during the cleaning of the respective filter (1, 31). Further disclosed are a system for detecting a cleaning process in a plant having such filters, and such a plant.

  • Publication number: 20160033369
    Abstract: In situations where first equipment of a first technical installation could hitherto not be monitored based on condition data of the first equipment from the first equipment alone, it is proposed that a first sensor measures first condition data of the first equipment and that art additional sensor measures additional condition data of an additional equipment of an additional technical installation. The first condition data and the additional condition data are transmitted to a sorting unit and processed by the sorting unit into a ranking list. A corresponding sorting unit and a system as well as a corresponding computer program and a computer program product are also disclosed.

  • Publication number: 20150241873
    Abstract: Monitoring a first system of a technical plant for producing a product is performed by feeding first input data into a first logic unit; evaluating the first input data by the first logic unit; outputting first output data by the first logic unit, the output data characterizing a first status of the first system monitored. To improve known concepts for status monitoring, the first input data includes—first sensor data provided by the first sensors located in the plant, first data calculated by a first process model, the first process model mapping a first process in the plant, or first automation data of a first function of a first automation system in the plant; first design data characterizing physical variables of the first system and/or the plant, first parameterization data variable and predefinable relating to the first system and or the plant, and operating data characterizing production of the product.
