Abstract

Provided is a plant equipment state gathering system which simplifies the work relating to attaching and/or replacing a detection device that detects the state of plant equipment. A plant equipment state gathering system is provided with a detection device, a mobile terminal, a network construction device and a data storage device. The detection device includes a tag unit that can store, in a non-contact manner, at least some setting information that at least includes network information for connecting to the network from the mobile terminal. The mobile terminal includes a tag control unit that allows the tag unit of the detection device to automatically store, in a non-contact manner, at least some of the setting information. When network information is stored in the tag unit of the detection device by the mobile terminal the network construction device uses this network information to determine whether to allow the connection of the detection device to the network.

First claim

The invention claimed is:

1. A plant equipment state gathering system, comprising:
a detection device, a mobile terminal, a network construction device, and a data storage device,
wherein the mobile terminal includes a tag control unit, the tag control unit contactlessly transmitting, to the detection device, network information for connecting the detection device to a network, the network being constructed by the network construction device,
wherein the detection device includes:
a detection unit detecting a state of plant equipment disposed in a plant,
a tag unit contactlessly receiving, from the mobile terminal, the network information and storing the received network information,
a network connection unit connecting the detection device to the network based on the received network information, and

wherein the detection device and at least transmits, to the network construction device via the network, 1) the detected state of the plant equipment and 2) specifying information for specifying the detection device,
wherein the data storage device 1) receives, from the network construction device, the state of the plant equipment and the specifying information of the detection device and 2) stores the received state of the plant equipment and the specifying information of the detection device,
wherein the detection device further includes a battery,
wherein a first amount of power is supplied to the detection device while the network information is stored in the tag unit of the detection device,
wherein a second amount of power is supplied to the detection device when the network information is not stored in the tag unit of the detection device, the second amount of power being smaller than the first amount of power, and
wherein the second amount of power supplied to the detection device when a network participation completion report is issued by the network construction device.

2. The plant equipment state gathering system according to claim 1 , wherein
the tag unit of the detection device stores the specifying information of the detection device,
the tag control unit of the mobile terminal contactlessly and automatically acquires the specifying information from the tag unit of the detection device, and
after the tag control unit of the mobile terminal acquires the specifying information from the tag unit of the detection device, the tag control unit of the mobile terminal transmits the network information to the tag unit of the detection device by the tag control unit.

3. The plant equipment state gathering system according to claim 1 , wherein
when the tag control unit of the mobile terminal transmits the network information to the tag unit of the detection device, the mobile terminal transmits the specifying information and the network information to the data storage device.

4. The plant equipment state gathering system according to claim 1 , wherein
the detection device further includes a report unit,
when the state of the plant equipment stored in the data storage device indicates an abnormal state of the plant equipment;
the data storage device transmits, to the network construction device, an abnormal state occurrence signal including the specifying information of the detection device that detected the abnormal state of the plant equipment,
the network construction device transmits a report start signal to the detection device specified in the specifying information included in the abnormal state occurrence signal, and
the detection device which received the report start signal starts a report process.

5. The plant equipment state gathering system according to claim 2 , wherein
when the state of the plant equipment stored in the data storage device indicates an abnormal state of the plant equipment;
the data storage device transmits, to the mobile terminal, an abnormal state occurrence signal including the specifying information of the detection device that detected the abnormal state of the plant equipment to the mobile terminal, and
after receiving the abnormal state occurrence signal, the tag control unit of the mobile terminal determines whether the specifying information of the detection device acquired from the tag unit of the detection device and the specifying information included in the abnormal state occurrence signal match each other.

6. The plant equipment state gathering system according to claim 5 , wherein
the detection device further includes a report unit,
when the state of the plant equipment stored in the data storage device indicates an abnormal state of the plant equipment;
the data storage device transmits, to the network construction device, an abnormal state occurrence signal including the specifying information of the detection device that detected the abnormal state of the plant equipment,
the network construction device transmits the report start signal to the detection device specified in the specifying information included in the abnormal state occurrence signal, and
the detection device which received the report start signal starts the report unit.

7. The plant equipment state gathering system according to claim 1 , wherein
the mobile terminal acquires current position information of the mobile terminal, and
the acquired current position information is included in the network information as a position at which the detection device is disposed.
