Abstract

A plant control and monitoring device includes a communication card having a first wireless communication chip on which a first unique ID is recorded, a CPU card having a second wireless communication chip on which a second unique ID is recorded, an input card having a third wireless communication chip on which a third unique ID is recorded, and a power supply unit having a fourth wireless communication chip on which a fourth unique ID is recorded. The first wireless communication chip reads out a unique ID from the second wireless communication chip or the fourth wireless communication chip, and transmits a read out unique ID to a maintenance tool through a control network. In a plant control and monitoring system, when the maintenance tool receives a unique ID transmitted through the control network, the maintenance tool collates the received unique ID with an ID database.

First claim

1 . A plant control and monitoring system, comprising;
a maintenance tool, having an ID database which correlates a unique ID with a component part that possess the unique ID, and holds a relation between the unique ID and the component part in memory and a plant control and monitoring device connected with a maintenance tool through a control network, wherein the plant control and monitoring device owns a communication card which possesses a first wireless communication chip on which a first unique ID is recorded, a CPU card which possesses a second wireless communication chip on which a second unique ID is recorded, an input card which possesses a third wireless communication chip on which a third unique ID is recorded, and a power supply unit which possesses a fourth wireless communication chip on which a unique ID is recorded, and wherein the first wireless communication chip that is possessed by the communication card reads out a unique ID from the second wireless communication chip or the fourth wireless communication chip, and transmits the read out unique ID to the maintenance tool through the control network, and when the maintenance tool receives a unique ID which is transmitted through the control network, the maintenance tool collates the received unique ID with the ID database.

2 . A plant control and monitoring system, comprising;
a maintenance tool, having an ID database which correlates a unique ID with a component part that possess the unique ID, and holds a relation between the unique ID and the component part in memory and a maintenance tool having an ID database which keeps in memory a correlation between a unique ID and a component part which possess the unique ID, and a plant control and monitoring device connected with a maintenance tool through a control network, wherein the plant control and monitoring device owns a communication card which possesses a first unique ID, a CPU card which possesses a second unique ID, an input card which possesses a third unique ID, and a system bath making connection among the communication card, the CPU card and the input card, and wherein the communication card reads out a second unique ID and a third unique ID from the CPU card and the input card by way of the system bath, and transmits the read out unique ID to the maintenance tool through the control network, and when the maintenance tool receives a unique ID which is transmitted through the control network, the maintenance tool collates the received unique ID with the ID database.

3 . The plant control and monitoring system according to claim 1 or 2 ,
wherein a recommended time for replacement of a component part is recorded in the ID database, where a unique ID of the component part is correlated with the time for replacement.

4 . The plant control and monitoring system according to claim 1 or 2 ,
wherein in the case that the maintenance tool judges that there is an injustice, after collating the received unique ID with the ID database, the maintenance tool reports a warning on a monitor display.

5 . The plant control and monitoring system according to claim 2 ,
further comprising a power supply unit possessing a first wireless communication chip on which a fourth unique ID is recorded.

6 . A plant control and monitoring system, comprising;
a maintenance tool having an ID database which correlates a unique ID with information on a component part that is correlated with the unique ID, and holds the unique ID and the information in memory and a plant control and monitoring device, connected with the maintenance tool through a control network, wherein the plant control and monitoring device owns a component part which has a IC tag on which the unique ID is recorded, and is to be mounted in a control panel, and a communication device which reads out a unique ID from the IC tag which is located in the control panel, and transmits the unique ID to the maintenance tool by way of the control network, and, when the maintenance tool receives a unique ID, which has been transmitted through the control network, the maintenance tool collates the received unique ID with the ID database and displays an outcome of the collation.

7 . The plant control and monitoring system according to claim 2 ,
wherein a recommended time for replacement of a component part is recorded in the ID database, where a unique ID of the component part is correlated with the time for replacement.

8 . The plant control and monitoring system according to claim 2 ,
wherein in the case that the maintenance tool judges that there is an injustice, after collating the received unique ID with the ID database, the maintenance tool reports a warning on a monitor display.
