Method for providing at least one item of information relating to a hydraulic system

A method for providing at least one piece of information about a hydraulic apparatus, wherein the following stages are performed:

• performing a detection of detection values at the apparatus, wherein the detection values are specific for measurements at different measuring points and at different apparatus components of the apparatus,
• performing a transmission of the detected detection values to a processing component,
• providing apparatus information about at least a specification of the apparatus or the measurements, wherein providing of the apparatus information is performed at the processing component to provide the transmitted detection values with the apparatus information and wherein the apparatus information is static information about the apparatus,
• performing processing of the transmitted detection values based on the provided apparatus information by the processing component, wherein as a result of the processing for at least one of the apparatus components at least one target variable is determined by at least a soft sensor system and at least one operating point,
• wherein the at least one target variable is at least one of a first variable or a second variable:
• where the first variable for a pump is a rotational speed, a flow rate, an inlet pressure, a delivery head, a power, a medium temperature at the pump, or a result of a vibration analysis of the pump,
• where the second variable for a valve is a stroke position, a flow velocity, a differential pressure ratio, an inlet and outlet pressure, a medium temperature at the valve, or a device status of the valve,
• wherein the at least one operating point is calculated at least on the basis of the at least one target variable or on the basis of the at least one parameter, and wherein an evaluation of the at least one apparatus component is carried out on the basis of the result of the processing, and wherein the at least one target variable is a virtual value at the at least one operating point where no real measured values of the at least one target variable are available.
