Abstract

An equipment management system structured by a monitoring apparatus to monitor equipment of a facility being monitored and retrieve operation data, a database apparatus in which the operation data retrieved by the monitoring apparatus is recorded, and a database client apparatus to send and receive information to and from the database apparatus via a network, display the data recorded in the database apparatus, and enter data. The database apparatus records maintenance reference values for the equipment of the facility being monitored and the monitoring apparatus or database client apparatus outputs a display or printout prompting an execution of maintenance work when the operation data is in excess of or close to the maintenance reference values.

Claims

1. An equipment management system comprising:

a monitoring apparatus to monitor equipment of a facility being monitored and retrieve operation data;

a database apparatus in which the operation data retrieved by the monitoring apparatus is recorded; and

a database client apparatus to send and receive information to and from the database apparatus via a network, display the data recorded in the database apparatus, and enter data,

wherein said database apparatus records maintenance reference values for the equipment of the facility being monitored and said monitoring apparatus or said database client apparatus outputs a display or printout prompting an execution of maintenance work when the operation data is in excess of or close to the maintenance reference values, and

wherein, after the equipment of the facility being monitored is serviced, an equipment operation start date is entered from said database client apparatus, a check is made based on the equipment operation start date as to whether a maintenance period is exceeded or will soon be exceeded, and a display or printout prompting an execution of maintenance work is output to said monitoring apparatus or said database client apparatus.
