- the result of the frequency evaluation can thus be a spectrum whose values are represented digitally by the monitoring information.
- the monitoring component is designed to be structurally separate from the object and/or the processing system.
- the monitoring component can thus also be used for monitoring during ongoing operation of the object and without structural adjustments to the object for the installation of the monitoring component due to the separate design to the object. In this way it can also be made possible for the monitoring component to monitor a number of objects.
- the separate training for the processing system makes it possible to use a central processing system, which can be connected to a number of monitoring components via the at least one network.

So e.g. eg, the event of opening a door, with the door as the object, can affect the detection parameters used in a reproducible manner. This makes it possible to recognize such influences by certain values or patterns or anomalies in the monitoring information.
- the monitoring information advantageously includes the combination of the values and can optionally also be evaluated as a function of time (e.g. based on the progression over time). The temporal correlation of the occurrence of this influence with the various detection parameters can also be specific to the object parameter. Therefore, it may be useful to time-synchronize the acquisition and/or the monitoring information that is output.

- Exceeding predefined threshold values of the amplitudes of specific frequency components and/or a specific frequency pattern can provide conclusions about the object parameter.
- an optionally empirically determined assignment of certain predefined spectra to certain object parameters or states can also be provided. Based on this assignment, the spectrum of the monitoring information can then be assigned to the corresponding object parameter or state, and monitoring can thus take place in a simple manner.
- the assigned object parameter or status is then the result of the evaluation. If the assignment is made to a critical object parameter or condition, which z. B. indicates an overload of the object, a warning message can advantageously be issued to a user.
- the evaluation means includes, for example, a predefined table for this assignment.
- the evaluation means can have at least one artificial neural network in order to carry out the processing, in particular evaluation, in accordance with machine learning using learned information from the evaluation means.

- the monitoring component can have at least one evaluation component, which comprises at least one DPU (data processing unit).
- the data of the evaluation component can have precise data stamps but they may not arrive at the processing system in a timely order, since, for example, millions of data may arrive from thousands of DPUs over multiple networks, each with their own latencies - a timestamp may arrive fractions of a second later, although that Event itself used to take place in real time.

- the reliability of the monitoring and in particular the evaluation 140 of the object parameter based on the monitoring information 240 is particularly reliable when a number of detection parameters are recorded by a number of sensors 25 .
- the piece of monitoring information 240 can then have at least one item of information about these recorded recording parameters. This information can be evaluated by the processing system 80 in order to determine a state of the object 5 .
- the use of a vibration in the vicinity of the object 5 is also an option. Mechanical vibrations, which travel more slowly through surfaces than electromagnetic waves or audio noise through air, can then be detected as acquisition parameters. Since the humidity and temperature may also correlate with the state of the object or the object parameter, it may also be possible to record these detection parameters. These then correlate into complex data that moves precisely in sync with time and that can accurately describe the energy exposure (EMI) that correlates to the state of the object 5 .
