Method and device for the diagnosis of technical devices disposed within an industrial installation
First Claim
1. A device for diagnosis of a plurality of processing devices that are disposed within an industrial installation used in a processing industry with sensors for detecting disturbance variables that affect the plurality of processing devices and influence the service life thereof, with data of said disturbance variables being processed by a simulation unit containing a stored device model in order to determine the expected service life of each said processing device, comprising an expert unit containing stored servicing instructions that outputs an associated maintenance instruction for at least two processing devices together with the expected remaining trouble-free operating time of the industrial installation via a central display unit when a lower service life limit of one of said processing devices is reached;
- andwherein the maintenance instructions contain a complete replacement of at least two of the processing devices and a replacement of parts of a processing devices requiring maintenance, with the processing device or part thereof to be replaced being given within the maintenance instruction.

Abstract
Disclosed is a method for diagnosing technical devices, especially pumps and valves, which are arranged within an installation used in the processing industry. According to said method, disturbance variables that affect the devices and influence the service life thereof are detected by means of sensory technology while the data of said disturbance variables is processed in a simulative manner in order to determine the expected service life of each device. Various maintenance instructions which are output along with the expected remaining trouble-free operating time of the industrial installation when a lower service life threshold value of one or several devices has been reached are stored in an expert unit.

10. A method for diagnosing a plurality of processing devices that are disposed within an industrial installation used in a processing industry, with disturbance variables that affect the plurality of processing devices and influence the service life thereof being detected by sensors, with data of said disturbance variables being processed in a simulative manner in order to determine the expected service life of each said processing device, said method comprising:
-
monitoring a service life limit for each of the plurality of processing devices, said service life limit being reached before the processing devices fail; storing various maintenance instructions in an expert unit, and outputting maintenance instructions for at least two processing devices together with an expected remaining trouble-free operating time of the industrial installation when a lower service life limit of one of said processing devices is reached; and wherein the maintenance instructions contain, as information, a complete replacement of at least two of the processing devices and a replacement of parts of a processing device requiring maintenance, with the processing devices or parts thereof to be replaced being given within the maintenance instruction. - View Dependent Claims (11, 12, 13)
