Information processing system, information processing method, mobile device, and computer-readable recording medium
An information processing system includes a number of field devices provided in a plant and a mobile device that acquires data from the field devices. The mobile device includes a data management unit that manages the field devices that are grouped for each plant area and a processing unit that acquires data using wireless communication from, out of the field devices managed by the data management unit, the field devices provided in the plant area selected by user operation.
1. An information processing system comprising:
a number of field devices provided in a plant; and
a mobile device configured to acquire data from the field devices, wherein
the mobile device includes
a data management unit configured to manage the field devices by using a list indicating the field devices that are grouped for each plant area, and
a processing unit configured to sequentially acquire data using wireless communication from, out of the field devices managed in the list, the field device for which a connection is successful from among the field devices provided in the plant area selected by user operation.
2. The information processing system according to claim 1 , wherein
the processing unit acquires data using wireless communication from the field device selected by user operation, out of the field devices indicated in an image of the plant area selected by the user operation; and
the data management unit selects one of the list-based sequential access management using the list and the image-based access management using the image according to the user operation.
3. The information processing system according to claim 2 , wherein the processing unit stops to acquire data from the field device for which the connection failed, and skips to a next field device in the list to acquire data.
4. The information processing system according claim 1 , wherein the processing unit generates at least one of a file including acquired data and a report document, used to report the acquired data.
5. The information processing system according to claim 1 , further comprising an app management unit configured to manage an application installed in the mobile device to check credential information of user's authority that allows at least a part of processing of the processing unit based on the user operation to be executed.
6. The information processing system according claim 1 , wherein the processing unit edits a parameter of the field device.
7. The information processing system according to claim 1 , wherein the processing unit generates log information concerning acquisition of data from the field device.
8. The information processing system according to claim 1 , wherein the processing unit acquires information stored in the mobile device or information from outside of the mobile device as support information to support maintenance work of the field device performed by a user.
9. The information processing system according to claim 1 , wherein the field devices are, in order to transmit the data, connected in a wired manner to a radio that performs wireless communication with the mobile device.
10. The information processing system according to claim 1 , wherein
the processing unit sequentially tries to connect to all of the field devices in the list to acquire data.
11. The information processing system according to claim 1 , wherein the processing unit stops to acquire data from the field device for which the connection failed, and skips to a next field device in the list to acquire data.
12. An information processing method comprising:
managing, by a mobile device, a number of field devices by using a list indicating the field devices that are grouped for each plant area; and
sequentially acquiring, by the mobile device, data using wireless communication from, out of the field devices managed in the list, the field device for which a connection is successful from among the field devices provided in the plant area selected by user operation.
13. A mobile device comprising:
a data management unit configured to manage a number of field devices by using a list indicating the field devices that are grouped for each plant area, each of the field devices being configured to allow direct wireless communication with the mobile device; and
a processing unit configured to sequentially acquire data using wireless communication from, out of the field devices managed in the list, the field device for which a connection is successful from among the field devices provided in the plant area selected by user operation.
14. A computer-readable recording medium having stored therein an information processing program that causes a computer to perform a process comprising:
managing a number of field devices by using a list indicating the field devices that are grouped for each plant area; and
sequentially acquiring data using wireless communication from, out of the field devices managed in the list, the field device for which a connection is successful from among the field devices provided in the plant area selected by user operation.
