Method for operating a state monitoring system of a vibrating machine and state monitoring system

A method for operating condition monitoring systems of vibrating machines in the form of a vibrating conveyor or a vibrating screen, whereby the vibrating machines perform different movement patterns of any complexity in the direction of the x-axis, the y-axis and the z-axis and about the x-axis, the y-axis and the z-axis, wherein each respective one of the vibrating machines has a respective one of the condition monitoring systems, wherein each of the condition monitoring systems comprise at least one sensor designed for motion detection and/or acceleration detection, which is mounted on each respective one of the vibrating machines, the method comprising:

• providing, via the at least one sensor, measurement data which is further processed into characteristic values/condition variables in a processing unit connected with the at least one sensor;
• storing, in the processing unit connected with the at least one sensor, the characteristic values/condition variables as at least one data set;
• transmitting the at least one data set from the processing unit connected with the at least one sensor to a central data storage that communicates with the condition monitoring system of each of the vibrating machines;
• generating, via an external central processing unit, a knowledge base for an expert system taking into account information provided by the at least one data set in the central data storage for each of the condition monitoring systems and based on theoretical models;
• in order to assign the measurement data provided by the at least one sensor to a cause of damage, analyzing the at least one data set in the processing unit connected to the at least one sensor of each of the vibrating machines with the involvement of the knowledge base generated for the expert system, while correlating multiple ones of the characteristic values/condition variables and taking a temporal course of the multiple ones of the characteristic values/condition variables into account;
• and
• producing and/or displaying, via the processing unit connected to the at least one sensor, a diagnosis and/or a prognosis of an anomaly in the condition of the respective one of the vibrating machines, a recommendation for a maintenance measure or an indication of a failure time of the respective one of the vibrating machines.
