## Abstract

Provided is a plant instrument status collection system making it possible to more accurately manage operation information for plant instruments. A plant equipment status collection system according to the present invention comprises detection apparatuses, a portable terminal, a network construction apparatus, and a data storage apparatus. The portable terminal comprises a tag control unit that is capable of automatically and contactlessly acquiring specific information and date/time information stored in a tag unit of the detection apparatuses and is configured to be in communication with the data storage apparatus, wherein the portable terminal selects the specific information of any of the detection apparatuses in advance, determines whether or not the specific information acquired from the tag unit and the selected specific information are consistent, times this synchronously with the date/time information acquired from the tag unit in cases where these are consistent, and makes it possible to transmit operation content information representing predetermined operation content for the plant instruments, the selected specific information, and synchronized operation completion date/time information to the data storage apparatus.

## Claims

### Claim 1

A plant instrument status collection system, comprising:
a detection apparatus, a portable terminal, a network construction apparatus, and a data storage apparatus,
wherein the detection apparatus includes a detection unit detecting a state of plant equipment disposed in a plant, a network connection unit connectable to a network constructed by the network construction apparatus, and a clocking unit clocking date, and a tag unit storing specifying information for specifying the detection apparatus and date information, and capable of contactlessly transmitting the specifying information and the date information to the portable terminal, at least transmits the state of the plant instrument detected by the detection unit and specifying information to the network construction apparatus via the network,
wherein the data storage apparatus includes a storage unit at least storing the state of the plant equipment received from the network construction apparatus, and the specifying information of the detection apparatus, and
wherein the portable terminal includes a tag control unit capable of contactlessly and automatically acquirable the specifying information and the date information which are stored in the tag unit, and is configured to be able to communicate with the data storage apparatus, selects the specifying information of any of the detection apparatus in advance, and determines whether the specifying information acquired from the tag unit and the selected the specifying information match each other, clocks date in synchronization with the date information acquired from the tag unit if these match each other, and makes it possible to transmit the selected specifying information clocked work completion date information together with work contents information indicating predetermined work contents with respect to the plant instrument to the data storage apparatus.

### Claim 2 (depends on 1)

The plant instrument status collection system according to claim 1, wherein the clocking unit clocks date via the network in synchronization with other detection apparatus, the network construction apparatus and/or the data storage apparatus.

### Claim 3 (depends on 1)

The plant instrument status collection system according to claim 1, wherein the portable terminal is provided with a report unit reporting whether the specifying information acquired from the tag unit and the specifying information acquired from the data storage apparatus match each other.
