Field device management system

A maintenance management system for maintenance management of field devices in industrial processes located at different geographical locations remote from each other, said maintenance management system comprising:

• a local maintenance management system in association with each of the industrial processes,
• wherein the local maintenance management systems of said industrial processes are arranged to form a network and to communicate with each other and to exchange information relating to maintenance management of the field devices to learn and utilize the information on a network level,
• wherein each of said local maintenance management systems is arranged to control local maintenance management parameters independently based on data collected locally and data received from other local maintenance management systems, each of said local maintenance management systems comprises:
• a knowledge database arranged to store knowledge types of at least one of application-specific knowledge data, field device-specific knowledge data, and field device-type specific knowledge data;
• an analyzer arranged to analyze conditions of the field devices based on measurement data obtained from a respective local process and knowledge data obtained from said knowledge database, said analyzer is further able to change value of at least one maintenance parameter in the respective local process, when required according to results of an analysis;
• and
• a knowledge database controller arranged to modify content of said knowledge database based on maintenance management history data collected locally and maintenance management history data received from the other local maintenance management systems.

A maintenance management system for managing field devices in an industrial process, said maintenance management system comprising:

• a maintenance management system communication mechanism arranged to communicate with respective maintenance management systems of industrial processes of other plants located geographically apart from each other in order to transmit and receive data which relates to a maintenance of field devices;
• and
• a maintenance management parameter adjusting mechanism arranged to adjust maintenance management parameters of field device types in a self-learning manner based on data collected locally and data received from said other maintenance management systems,
• said maintenance management system further comprising:
• a knowledge database arranged to store knowledge types of at least one of application-specific knowledge data, field device-specific knowledge data, or field device-type specific knowledge data;
• an analyzer arranged to analyze a condition of the field devices based on measurement data obtained from a respective local process and knowledge data obtained from said knowledge database, said analyzer is further able to change value of at least one maintenance parameter in the respective local process, when required according to results of an analysis;
• and
• a knowledge database controller to modify content of said knowledge database based on maintenance management history data collected locally and maintenance management history data received from the other maintenance management systems.
