Abstract

A server displays information about a plurality of industrial machines on a display of a client computer. The server includes a storage device, a processor, and a communication device. The storage device stores state data indicative of states of a plurality of industrial machines. The processor determines remaining lives of the plurality of industrial machines from the state data. The processor generates data indicative of a machine list screen. The machine list screen includes identifiers of the plurality of industrial machines and the remaining lives. The communication device outputs the data indicative of the machine list screen to a client computer via a communication network.

First claim

The invention claimed is:

1. A server for displaying information about a plurality of industrial machines on a display of a client computer, the server comprising:
a storage device that stores first data and state data indicative of states of the plurality of industrial machines, the first data being extracted from the state data;
a processor configured to
determine whether the first data is indicative of an abnormal condition of the plurality of industrial machines;
determine remaining lives of the plurality of industrial machines from the state data and
generate data indicative of a machine list screen including identifiers of the plurality of industrial machines and the remaining lives and data indicative of an individual machine screen including identifiers of a plurality of moving parts included in at least one industrial machine selected from the plurality of industrial machines; and

a communication device configured to
receive the first data;
transmit a request for the state data upon determining that the first data is indicative of the abnormal condition;
receive the state data responsive to the request for the state data; and
output the data indicative of the machine list screen and the data indicative of the individual machine screen to the client computer via a communication network,

each of the plurality of industrial machines including a motor and a plurality of drive systems, each of the plurality of drive systems including a plurality of moving parts connected to the motor,
the machine list screen including the identifiers of the plurality of industrial machines, and respective identifiers and remaining lives of the plurality of drive systems of each of the plurality of industrial machines, and
the individual machine screen including an identifier of the drive system including the moving part having a high replacement priority, and an identifier of the moving part having a high replacement priority and the remaining life.

2. The server according to claim 1 , wherein
the plurality of industrial machines are arranged in a plurality of areas,
a plurality of local computers communicatively connected to each of the plurality of industrial machines are arranged in the plurality of areas,
the communication device receives the first data and the state data from the plurality of local computers, and
the machine list screen includes the identifiers and the remaining lives of the plurality of industrial machines arranged in the plurality of areas.

3. The server according to claim 1 , wherein
the machine list screen includes the remaining lives of the plurality of drive systems included in each of the plurality of industrial machines.

4. The server according to claim 3 , wherein
the machine list screen displays the plurality of drive systems in different colors according to the remaining lives.

5. The server according to claim 1 , wherein
on the machine individual screen, at least a part of the plurality of drive systems is listed in order from the one having the shortest remaining life.

6. The server according to claim 1 , wherein
the processor is further configured to determine from the state data the one having the shortest remaining life among the plurality of movable parts, and
the machine individual screen includes the identifier and the remaining life of the movable part having the shortest remaining life.

7. A method performed by a processor to display information about a plurality of industrial machines on a display of a client computer, the method comprising:
acquiring first data, the first data being extracted from state data indicative of states of the plurality of industrial machines;
determining whether the first data is indicative of an abnormal condition of the plurality of industrial machines;
transmitting a request for the state data indicative of the states of the plurality of industrial machines upon determining the abnormal condition;
acquiring the state data indicative of the states of the plurality of industrial machines;
determining remaining lives of the plurality of industrial machines from the state data;
generating data indicative of a machine list screen including identifiers of the plurality of industrial machines and the remaining lives and data indicative of an individual machine screen including identifiers of a plurality of moving parts included in at least one industrial machine selected from the plurality of industrial machines; and
outputting the data indicative of the machine list screen and the data indicative of the individual machine screen to the client computer via a communication network,
each of the plurality of industrial machines including a motor and a plurality of drive systems, each of the plurality of drive systems including a plurality of moving parts connected to the motor,
the machine list screen including the identifiers of the plurality of industrial machines, and respective identifiers and remaining lives of the plurality of drive systems of each of the plurality of industrial machines, and
the individual machine screen including an identifier of the drive system including the moving part having a high replacement priority, and an identifier of the moving part having a high replacement priority and the remaining life.

8. The method according to claim 7 , wherein
the plurality of industrial machines are arranged in a plurality of areas,
a plurality of local computers communicatively connected to each of the plurality of industrial machines are arranged in the plurality of areas,
the acquiring the first data and the state data includes receiving the first data and the state data from the plurality of local computers, and
the machine list screen includes the identifiers and the remaining lives of the plurality of industrial machines arranged in the plurality of areas.

9. The method according to claim 7 , wherein
the machine list screen includes the remaining lives of a plurality of drive systems included in each of the plurality of industrial machines.

10. The method according to claim 9 , wherein
the machine list screen displays the plurality of drive systems in different colors according to the remaining lives.

11. The method according to claim 7 , wherein
on the machine individual screen, at least a part of the plurality of drive systems is listed in order from the one having the shortest remaining life.

12. The method according to claim 7 , wherein
the processor is further configured to determine from the state data the one having the shortest remaining life among the plurality of movable parts, and
the machine individual screen includes the identifier and the remaining life of the movable part having the shortest remaining life.

13. A system comprising:
a storage device that stores first data and state data indicative of states of a plurality of industrial machines, the first data being extracted from the state data;
a processor configured to
determine an abnormality in the plurality of industrial machines from the first data;
determine remaining lives of the plurality of industrial machines from the state data upon determining the abnormality from the first data; and
generate data indicative of a machine list screen including identifiers of the plurality of industrial machines and the remaining lives and data indicative of an individual machine screen including identifiers of a plurality of moving parts included in at least one industrial machine selected from the plurality of industrial machines; and

a display that displays the machine list screen and the individual machine screen,
each of the plurality of industrial m
