A maintenance work support system comprising: a database in which support information for supporting maintenance work is registered; a camera-image acquisition unit configured to acquire a camera-image imaged by a camera that is mounted on a terminal possessed by a worker performing the maintenance work; a position/attitude estimation unit configured to estimate a position and attitude of the terminal based on information that is obtained by at least one device mounted on the terminal; a target recognition unit configured to recognize a target of the maintenance work depicted in the camera-image; and a superimposed display unit configured to perform display processing in such a manner that the support information corresponding to the target acquired from the database is superimposed on least part of an image of the target visually recognized by the worker.

Maintenance work support system and maintenance work support method

A field cooperation system according to an embodiment includes a terminal device and a management device. The terminal device includes: a position measurement unit; and a display unit. The position measurement unit measures a position of the terminal device. A display device displays a display image. The management device includes: a database; and a display control unit. The database stores three-dimensional data representing a layout of a structure. The display control unit generates a display image to illustrate the structure and an icon representing the position of the terminal device on the display unit in correspondence with each other based on the three-dimensional data and the measured position of the terminal device.

Field cooperation system and management device

According to the embodiment, there is provided a blade vibration measuring apparatus, having, a contactless displacement sensor which outputs a displacement measurement signal as measuring a displacement of a turbine moving blade in a rotation axis direction, a blade top position identifying device which outputs a blade top position identification signal to identify a top position based on a distance between the contactless displacement sensor and the top position of the turbine moving blade as receiving the displacement measurement signal output from the contactless displacement sensor, and a blade vibration calculating device which calculates vibration amplitude and a vibration frequency of the turbine moving blade based on temporal variation of the distance between the contactless displacement sensor and the top position of the turbine moving blade as receiving the blade top position identification signal output from the blade top position identifying device.
