<p>PROBLEM TO BE SOLVED: To provide an integral control system having a database collecting and controlling function for performing highly reliable message collection and high performance message retrieval and a maintenance controlling function for preparing a schedule whose contents are flexible and detail, and for recognizing necessary maintenance work information. SOLUTION: An HIS part 2 is a server for collecting messages from field equipment. A PRM data server 1 collects those messages through the HIS part 2 as necessary, and stores the messages in a database 12 so that a first automatic message collecting function can be realized. The PRM data server 1 stores the messages in a temporary file 13 when the database 12 is stopped, and moves the contents of the temporary file 13 to the database 12 after the database 12 is restarted. Moreover, the PRM data server 1 regularly arranges the storage contents by referring to a log file 11 so that a second automatic export function can be realized.</p> |
