Abstract

The invention relates to a condition monitoring system for machines equipped with a machine control system (12) and including rotating machine elements. The condition monitoring system is based on the measurement and monitoring of various variables during the operation of the machines. The condition monitoring system includes sensing elements (10) for the measurement of desires variables as well as processing equipment (25) and storing and analyzing equipment (28) for the creation and storage of the machine'"'"'s condition information. The storing and analyzing equipment (28) is separately arranged in connection with each machine as a module (13) separate from the machine control system (12).

Claims

1. A condition monitoring system for machines equipped with a machine control system and including rotating machine elements, which condition monitoring system is based on that measurement and monitoring of various variables during the operation of the machines and including

one or more pieces of communication equipment,

sensing elements arranged in connection with the machine to be monitored for measuring desired variables, to be monitored for measuring desired variables,

processing equipment for the measuring data collected with the sensing elements, and

storing and analyzing equipment for the result data formed by the processing equipment based on the measuring data, for the purpose of creating and storing the condition information of the machine,

characterized in that the condition monitoring system includes modules, including the storing and analyzing equipment, arranged closely in connection with each machine separately, and which module is arranged separate from the machine control system, and which module is arranged for creating and storing the condition information of the machine.

2. A condition monitoring system according to claim 1, characterized in that the processing equipment is at least partly arranged in connection with the module and/or the sensing elements.

3. A condition monitoring system according to claim 1, characterized in that the module has an integrated arrangement and its design is independent of the machine design.

4. A condition monitoring system according to claim 1, characterized in that for connecting the machine control system to the condition monitoring system the communication equipment includes one or more communication interfaces, of which at least one is bi-directional.

5. A condition monitoring system according to claim 1, characterized in that the condition monitoring system includes a configuration database, from which the design and configuration data of each machine as well as the desired analyzing software are transferred to the storing and analyzing equipment using the communication equipment.

6. A condition monitoring system according to claim 5, characterized in that the design and configuration data is transferred at the production or startup stage of each machine or later as changes take place in the design and/or configuration data and/or analyzing software.

7. A condition monitoring system according to claim 1, characterized in that the storing and analyzing equipment includes an analyzing processor as well as read-alter memory and storing memory equipment, of which the read-alter memory equipment is for the operating system and the analyzing software, and the storing memory equipment is for the configuration and result data.

8. A condition monitoring system according to claim 7, characterized in that the configuration data and/or analyzing software are adapted for each machine.

9. A module to be used in a condition monitoring system according to claim 1 including communication equipment for the sensing elements and in which condition monitoring system the machine control system is arranged in connection with the machine to be monitored, characterized in that the communication equipment, processing equipment and storing and analyzing equipment are arranged in one unit to be adapted to the machine, independent of the machine design.

10. A module according to claim 9, characterized in that the communication equipment between the sensing elements and the module is fixed and/or wireless.
