It is not necessary to draw the guide 25 so as to connect all the previous designated points 28 and the designated points 27 on the screen in all combinations, so that it is easy to see and the position on the screen can be grasped. It should be clear. For example, the previous designated point 2
8 in time series, each previous designated point 28 and designated point 2
If there is a line segment connecting 7 (current designated point), it is enough to grasp where in the drawing on the screen it is displayed.

The operation of the embodiment of the site support system according to the present invention will be described with reference to FIGS. In the stage of starting the production and inspection work, the worker A16 who performs the production and inspection work of the membrane LNG ship 18
Etc. are preparing for the next. The WPC shown in FIGS. 1 to 3 is mounted, and the LPC shown in FIG.
The AN 17 is connected to the work management server 122. The work management server 122 includes a work database 123
Is connected, and the information can be retrieved at any time.

Referring to FIG. 6, membrane LNG ship 18
The worker A16 or the like who is working at the manufacturing site of the HMD extracts the drawings and the like necessary for performing the work from the work management server 14 or the HD of the worker A WPC 16-1, and reads out the HMD.
7 is displayed. At this time, the initial state of the displayed drawing and the like is the entire display of the drawing and the like shown in FIG. 6A (however, there is no spider pointer 23, the designated point 27, the previous designated point 28, and the guide 25). The worker A16 operates a pull-down menu or a button on the screen to display the spider pointer 23 on the screen. And worker A16
Designates a place (designated point) to be enlarged with the spider pointer 23 and enlarges a drawing or the like near the designated point with the zooming dial 26 (FIG. 6B). Then, work is performed using the screen.

When the worker A16 wants to confirm another place in the drawing, the operation is performed as follows. While the drawing or the like is being enlarged, the spider pointer 23 currently at the designated point 27 is dragged with the mouse, and is moved as it is to a place to be checked. And the spider pointer 23
Specify the point with. At this time, since a line segment (guide 25) extends from the immediately preceding designated point to the moving spider pointer 23, the direction from the immediately preceding designated point can be known without enlarging the drawing or the like, and the drawing is enlarged. Also do not lose track of the place on the drawing. At this time, the position on the drawing (coordinates, etc.)
May be displayed beside the spider pointer 23. For example, (0, 0)
The position in the drawing is displayed with the upper right as (1.0, 1.0).

When a position on the drawing is designated by the designated point 27, another detailed drawing or design data of the designated point 27 can be read out by a menu. For example, there is a method in which a menu for requesting detailed drawings and detailed data is displayed on the screen after specifying the specified point 27 and right-clicking the mouse or from a pull-down menu on the screen. The control unit of the present site support system (such as the control unit 2-1 of the WPC 16-1 for the worker A) requests the details based on the position information of the display screen on the drawing and the input menu information. The drawing and design data are specified, and the work management server 14 is inquired of the information via the wireless LAN. The work management server 14 acquires the requested detailed image and design data from the work management database 15 and
To the WPC 16-1 for use. WPC16- for worker A
1 displays a detailed image and design data on the display unit 4-1. If the data is in the HD of the worker A WPC 16-1, it is needless to ask the work management server 14, and the worker A WPC 16-1 displays the detailed image and the design data on the display unit 4-1. . Through such a process, it is also possible to easily acquire detailed information not specified in the displayed drawing for the designated point 27 designated by the spider pointer 23.

When the number of points designated by the spider pointer 23 increases, the designated point 27, the previous designated point 28 (-1 to 4) and the guide 25 (-1 to 7) shown in FIG. Is done. Then, even when the designated point 27 is enlarged, the position shown in FIG. 6B is obtained, and the position on the entire figure can be easily grasped from the relation with the guide.

When the worker A16 wants to check another place on the drawing, he or she reduces the drawing to an appropriate size with the zooming dial 26, designates the point to be checked with the spider pointer 23, and uses the zooming dial 26 to designate the designated point. A method of enlarging a drawing or the like in the vicinity to an appropriate size again is also possible. Also in this case, since the spider pointer 23 and the guide 25 have functions, it is possible to easily grasp the current position of the designated point after re-enlargement. In particular, when there are many places to be enlarged, it becomes a very effective position checking means. Also, the size of the enlargement can be freely changed by the zooming dial 26, and can be selected according to the work situation.

In this way, when a worker or the like uses a WPC, even if a large drawing or the like is displayed on the HMD 7 or another display device attached to the WPC, the whole and local areas can be displayed simultaneously and continuously. Etc. can be reduced. Therefore, the work efficiency is improved, the construction period can be shortened, and the cost can be reduced.

In this embodiment, an example relating to the work on the wall surface of the membrane tank 19 of the membrane LNG ship 18 has been described.
However, this can be used for all operations using drawings and the like. For example, consider the case of searching for something on a shelf in a warehouse. Referring to FIG.
FIGS. 7A and 7B show an overall view and an enlarged view of the warehouse. The meanings of the reference numerals in the figure are the same as those in FIG.

First, the searcher wearing the WPC accesses the warehouse database having the inventory data of the warehouse from the WPC in the warehouse via the wireless LAN. Then, the searcher uses a search tool to search the stock data of the warehouse for a place where the required parts are stored. The search tool displays the position where the component is stored on the screen. In that case, the position is displayed on the entire drawing of FIG. The searcher specifies the position with the spider pointer 23. Then, the position is enlarged by the zooming dial 26, and a more accurate position and a part number in the warehouse are confirmed (FIG. 7 (b)). The searcher searches for the next necessary part as necessary, because the location of the housed part can be accurately known.

When there are a plurality of parts to be searched, it is necessary to know where each part is located in the warehouse.
In this case, since the spider pointer 23 is used, it is possible to clearly grasp the positional relationship of each part in the warehouse. For example, FIG. 7 shows a location and a positional relationship in a warehouse accommodating four parts. With the guide 25 function of the spider point 23, it is possible to understand the respective positional relationships.

When a position on the drawing is designated by the designated point 27, it is also possible to read out detailed data relating to the storage at the designated point 27 by using a menu. For example, there is a method in which a menu for requesting detailed drawings and detailed data is displayed on the screen after specifying the specified point 27 and right-clicking the mouse or from a pull-down menu on the screen. The control unit of the worker WPC specifies detailed data relating to the requested storage item based on the position information of the display screen on the drawing and the information of the input menu, and sends the work management server 14 a wireless LAN. Query the information via The work management server 14 acquires detailed data related to the requested storage item from the work management database 15 and transmits the data to the worker WPC. Display part 4 for worker W
Display detailed images and design data on -1. Through such a process, it is also possible to easily acquire detailed information not specified in the displayed drawing for the designated point 27 designated by the spider pointer 23.

The present invention is not limited to WPC, but can be applied to a case where an object larger than the display screen is displayed and the display content is enlarged or reduced. In addition, not only when using WPC when manufacturing a membrane LNG ship,
When performing work while displaying a drawing or the like on a display unit of the WPC using another WPC (for example, an aircraft, a rocket, another ship, a chemical plant, a power plant, a gas turbine,
The present invention can also be applied to manufacturing, maintenance, inspection, etc.).

The above-mentioned operations can be performed by voice guidance, voice command input, and numerical input using the voice recognition function of the WPC.
