Embodiment Construction
[0023] figure 1 An embodiment of the computer system 100 according to the present invention for monitoring the system components K1 to Kp of the production system 200 is shown.
[0024] The fluid-conducting cascade production system 200 has a plurality of system components that are installed in a cascade arrangement and are suitable for processing liquids (fluids) guided through the production system 200. Here, each system component performs processing steps for the processing or transformation of fluids. The system components may be sequentially arranged in a cascade manner as shown in the embodiment. However, there may also be branches, which are parallel to the fluid path section by section, wherein the parallel paths gather together again in the last cascade stage Kp at the latest.
[0025] An example of a cascade production system 200 that directs fluids is a water treatment system for dialysis. Examples of the cascaded system components K1 to Kp of this water treatment syst...

The invention relates to a computer system (100), to a computer-implemented method, and to a computer program product for determining an operating state of at least one system component (K1 to Kp) in a fluid-conducting cascading production system (200). The computer system comprises an interface (110), which is configured to receive a first and a second pressure-pulse signal (201, 202), wherein the first pressure-pulse signal (201) characterizes a pressure pulse before the passage through the production system (200) and the second pressure-pulse signal (202) characterizes the pressure pulse after the passage through the production system (200). The system also comprises a memory unit (120), which is configured to store a plurality of transfer functions (TF1 to TFm), wherein a transfer function (TF1 to TFm) describes an operating-state-dependent impulse response of at least one system component (K1 to Kp) to the pressure pulse. The system also comprises an evaluating unit (130), which is configured to determine a real transfer function for the production system from the first and second pressure-pulse signals (201, 202) and to compare the real transfer function of the production system (200) with the stored plurality of transfer functions (TF1 to TFm) for the system components in order to determine the operating state of a specific system component (K1 to Kp) of the production system (200) therefrom.
Description
Technical field [0001] Generally speaking, the present invention relates to an electronic data processing system, in particular to a computer system, a computer program product, and a computer-implemented method for monitoring the components of a cascade production system for guiding fluids . Background technique [0002] In cascaded production systems that guide fluids, such as water treatment systems for dialysis, sensors for monitoring specific parameters are used after each production or purification step. The sensor provides measurement data for each component of the production system monitored by the sensor, which can be used to determine the operating status of the corresponding component. An example of such a specific parameter is the pressure difference between the inlet pressure of a specific component and the outlet pressure of a specific component. Therefore, for example, if the sand filter is filled with clean sand or the filter is contaminated with floating partic...
