Next, the instruction device 3 of the outfitting support system S will be described. FIG. 7 shows this outfitting support system S
FIG. 4 is an explanatory diagram showing a data flow in the embodiment. Hereinafter, description will be made with reference to FIG.

As shown in FIGS. 3 and 7, the outfitting support system S includes an indicating device 3 connected to a bogie controller 23 of the bogie 2. For example, the pointing device 3 and the bogie controller 23
They may be connected to each other by a wireless LAN or the like. The pointing device 3 may be constituted by a personal computer.

In the pointing device 3, drawing data is stored in a storage device (not shown). The drawing data includes a plan view, a side view, a detailed view, and the like of the outfitting block. Note that the drawing data is stored in a database, and the indicating device 3 can search for a section of the outfitting block that is divided for each outfitting stage in the drawing.

Prior to the actual outfitting work, the work instructor uses the indicating device 3 to instruct the work order of each outfitting stage and to indicate a screen to be projected on each outfitting stage. The worker works on one outfitting stage at a time, and after completing the work on one outfitting stage, moves to the next outfitting stage. Therefore, the work instructor made the outfitting work for the frame K to be performed most efficiently as a whole,
The work order of each of these outfitting stages is determined in advance, and the work order is instructed to the instruction device 3.

FIG. 6 shows each outfitting stage G in the skeleton K.
FIG. As shown in FIG. 6, the frame K is divided into a plurality of outfit stages G. Then, the work instructor determines the work order of each of the outfitting stages G. For example, the work instructor selects each outfitting stage G according to the most preferable work order while referring to a plan view of the outfitting block divided into a plurality of outfitting stages G and displayed on a screen (not shown) of the indicating device 3. I will do it. Then, the instruction device 3 recognizes the work order of each outfitting stage G selected by the work instructor. In the example shown in FIG. 6, the outfitting work for each outfitting stage G is G
The operations are performed in the order of [1] to G [16].

The pointing device 3 moves the main body 22 of the bogie 2 above the respective outfitting stages G (corresponding position) based on the work order of each outfitting stage G instructed by the work instructor.
Then, movement control data for instructing the bogie controller 23 to move in the shortest time according to the work order is created. Then, as shown in FIG. 7, the pointing device 3 transmits the created movement control data to the bogie controller 23.

The work instructor uses the indicating device 3 to indicate a portion to be projected in correspondence with each outfitting stage G in the drawing data stored in the storage device in the indicating device 3. Go on. The worker performs actual outfitting work with reference to the side view and the detailed view together with the plan view of the block. For this reason, the work instructor instructs a part necessary for the work in the outfitting stage G in the plan view of the outfitting block and other drawings with respect to each outfitting stage G.

Further, the work instructor checks each outfitting stage G
Of the projection portions E1 in the projection area E of FIG. For example, as shown in FIG. 5, the work instructor determines that a certain outfitting stage G is to project the plan view M1 on the three projection portions E1. Then, the work instructor determines to project another drawing (a side view, a detailed view, or the like) on a projection portion other than the projection portion E1 on which the plan view M1 is to be projected.

The work instructor determines the information thus determined,
That is, in each outfitting stage G, information indicating which drawing is to be projected on which projection portion E in the projection area E is input to the instruction device 3. As shown in FIG. 7, the instruction device 3 transmits the information and the drawing data including the drawing selected as described above to the projection control device 26 as projection instruction data.

Thus, prior to the actual outfitting work,
The movement control data is transmitted from the instruction device 3 to the carriage control controller 23, and the projection control device 2
6 is transmitted with the projection instruction data.

Next, the flow of data during an actual outfitting operation will be described. First, at the start of the outfitting operation, the bogie controller 23 reads out the movement control data and moves the main body 22 of the bogie 2 to a position above the first outfitting stage G [1]. That is, the bogie controller 23
Controls the traveling motor drivers 214 and 214 to move the traveling frame 21 in the traveling direction, and controls the traversing motor drivers 223 and 223 to move the main body 22 in the traversing direction.

The sensor unit 25 always obtains measurement data corresponding to the position in the traveling direction and the position in the traverse direction of the main body unit 22 of the bogie 2 by using the position sensors 251 and 252, and transmits the measurement data. It is transmitted to the bogie position calculating device 24. Then, the bogie position calculating device 24 converts the measurement data into position data indicating the position of the main body 22 of the bogie 2 in the running direction and the position in the transverse direction. Further, the bogie position calculating device 24
Transmits the position data to the carriage controller 23 and the projection controller 26, respectively.

The carriage controller 23 can accurately stop the main body 22 at a desired position by recognizing the position of the main body 22 of the carriage 2 based on the position data.

When the main body 22 of the carriage 2 stops,
The projection control device 26 recognizes on which outfitting stage G the main unit 22 is stopped based on the position data and the position conversion data stored in the storage device in advance. The position conversion data is data indicating a conversion relationship between the coordinate system of the position data acquired from the carriage position calculation device 24 and the coordinate system of the drawing data in the projection instruction data.

Then, the projection control device 26 projects an image on the outfitting stage G. That is, the projection control device 26 controls the projection instruction data acquired from the instruction device 3,
Further, a projection screen is created based on the offset data and the size data stored in the storage device, and the projection screen is projected on each projector 27.

Therefore, first, an image is projected on the outfitting stage G of [1], which is the first work object. For example, as shown in FIG. 5, on the outfitting stage G, a drawing (plan view) M1 is projected onto three projection portions E1 in the projection area, and another drawing is projected onto another projection portion. (Side view or detailed view, etc.) M2
Is projected. For this reason, the worker can refer to the plan view M1 and the other drawings M2 together, so that the worker can simply look at the floor surface of the skeleton K in the outfitting stage G without using a paper drawing. The outfitting work can be performed.

When the worker completes the outfitting work on the outfitting stage G of No. [1], the worker operates the remote controller or the like by himself without waiting for the instruction from the work instructor. To notify the completion of work. Then, the bogie controller 23 moves the main body 22 of the bogie 2 to a position above the next [2] outfitting stage G according to the movement control data.

When the main body 22 of the carriage 2 stops, the projection control device 26 stops the main body 22 on the No. 2 outfitting stage G based on the position data and the position conversion data. Recognize that Further, the projection control device 26 projects a corresponding image on the outfitting stage G. That is, the projection control device 26 creates a projection screen based on the projection instruction data, the offset data, and the size data and causes each projector 27 to project the projection screen. The worker can perform the outfitting operation in the same manner as described above with reference to the plan view M1 and the other drawings M2 displayed on the outfitting stage G.

When the worker finishes the outfitting work on the [2] outfitting stage G and notifies the bogie control controller 23 of the completion of the work, the bogie control controller 23 similarly sets Body part 22 of cart 2
Is moved to a position above the next outfitting stage G, the projection control device 26 causes each projector 27 to project an image corresponding to the outfitting stage G, and the worker performs outfitting work.

As described above, the outfitting work is sequentially performed on each outfitting stage G in accordance with the working order. In each outfitting stage G, the worker can refer to both the plan view M1 and the other drawings M2, so that there is no need to search for paper drawings, and
Work time is reduced. Further, the worker does not need to wait for an instruction from the work instructor when moving to the next outfitting stage G after completing the work on each outfitting stage G. For this reason, the time required for the outfitting work for the entire frame K is reduced.

[0050]

According to the outfitting support system configured as described above, when a drawing is projected on the projection area of each outfitting stage in the skeleton according to the working order of the outfitting stage, the worker can work in an efficient working order. , The outfitting operation can be performed. When the outfitting support system projects a plurality of drawings on each projection area, the worker can efficiently perform the outfitting work by simultaneously referring to the plurality of drawings. Therefore, the efficiency of the outfitting work is improved, and the work time is shortened.
