The present invention is a filler metal installation position checking method and a filler metal installation position checking system for confirming difference between installation position and designed position of a filler metal embedded in a wall surface. A standard surface targethaving known actual dimension and position to a wall surfaceis provided to the wall surfacewhere a filler metalis installed. The wall surfaceis photographed together with the standard surface targetto create image data. Using actual position and dimension of the standard surface targetand position and dimension of the standard surface targeton an image displayed by the image data, the image datais converted into corrected image datadisplaying an image corrected in a manner that the image is photographed from front of the wall surface. Design CAD datashowing actual designed position of the filler metal is read out and the images shown by the corrected image dataand the design CAD dataare outputted as images on one same display.

The present invention provides a module structure and a plant construction method capable of easily attaching a facility device of a plant and shortening a plant construction period. The module structure of the present invention includes a support member which temporarily supports a facility device component to be arranged in a cell constituting a plant at a designed position and which constitutes scaffolding for attaching the facility device component and forming the cell, a box-shaped frame which is possible to be carried into inner space of the cell while fixing the support member, and joint means which is detachably attachable and which temporarily assembles the support member and the frame.

A pipe installation support apparatus includes: a display control device for displaying images of pipes already installed and a pipe to be attached on a display device; an input device for inputting a movement instruction to move or rotate at least one of the image of the pipes; and a moving device for translating or rotating at least one of three-dimensional data of the pipes already installed and the three-dimensional data of the pipe to be attached based on the movement instruction when the movement instruction is input from the input device, wherein when the moving device translates or rotates the three-dimensional data, the display control device moves the images of the pipes already installed and the pipe to be attached displayed on the display device.

There is provided a method of recording an image by causing a subject to truly coincide with data relating to the subject. In a finished work recording method using image data by obtaining a product to be recorded and work contents to the product to be recorded as a work recording image, RFID tags(RFID tags) in each of which inherent tag data is recorded are attached to the product to be recorded and to the work recording worker. Thereafter, whether the tag data are true to the image data of a subject to be worked is determined by comparing a time difference between the time at which the tag data recorded in the RFID tagis read and the time at which the image data of the product to be recorded is obtained with a preset specified time. When it is determined that the tag data are truly associated with the image data, the image data associated with the tag data is recorded as a finished work. In contrast, it is determined that the tag data are falsely associated with the image data, the image data and the tag data are discarded.

Image data recording method, method of recording finished work by image data, image data recording apparatus, and finished work recording system using image data

According to an aspect of the present invention, an RFID tag has a long-distance communication RFID and a plurality of short-distance communication RFIDs. The RFID tag has tear-off lines for separating the short-distance communication RFID from the whole RFID tag, and when the short-distance communication RFID is separated, a loop-shaped antenna of the long-distance communication RFID is also cut up. And the RFID tag has an overall management identification code for identifying the whole tag before separation and a partial management identification code for identifying a partial tag after separation.
