Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides so-called C
A D ((OmpuH3r aided desi
This invention relates to a drawing device for creating a drawing of the object to be drawn.

The conventional method for creating design drawings using piping model engineering for thermal power plants, for example, is to manually create a comprehensive piping plan (hereinafter referred to as "general outline") from a separately created plant model, and then use the created general outline to For example, coordinates, shapes, etc. of piping and equipment are input into a computer using a data card or keyboard, and drawings are performed using CAD.

That is, as shown in FIG. 1 as an example of this piping model engineering, how many stages of piping models 1C are placed on the plant model 1 which includes the furnace or boiler body model 1a and the boiler steel frame model 1b, and the piping model 1C is constructed based on this piping model 1b. Create a general note 2 by hand, and enter the piping, 1 vessel, etc. seat 1 sheet, shape, etc. shown in this general note 2 into the computer 4 from the terminal device 3 using a data card or keyboard. The creation of the data card and the keyboard input operations must also be done manually.The computer 4 creates drawing data based on the input information such as coordinates and shapes of piping, equipment, etc., and sends this data to the printer 5. Output and draw. Complete drawings 6 such as assembly and detailed drawings drawn by the printer 5 are printed out (drawing generation (7)). Here, the terminal device 3 to the printer 5 use the so-called CAD system main body. It consists of

However, with this method, it is difficult to convert the model to CAD.
It takes a lot of time and effort to create general notes manually, and spending a long time in the planning stage can lead to problems with product delivery times if order plan 1, which has a short delivery time, is used. It arises.

The present invention has been made to solve the above-mentioned problems, and is a drawing device that creates a drawing of a drawing object through computer processing based on information about the drawing object in a plant model. , the main idea is to provide a sensor that reads at least the coordinates and shape of the object to be drawn among the colors, and to have a configuration in which the information on the coordinates and shape of the object to be drawn obtained by this sensor is directly input into the computer, thereby saving time. The purpose of the present invention is to provide a drawing device that enables improvement of work efficiency.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows a system configuration of an embodiment of the present invention.

In this example, piping model engineering is directly CA
As a means for application to D, a piping model 11 similar to the conventional one is used, and the automatic graphic input device 12 automatically inputs graphic information into the CAD device main body 13 to perform CAD.

That is, the automatic figure input device 12 detects the coordinates, shapes, colors, etc. of piping, equipment, etc. in the plans 1 to 11 using a position sensor 12a that uses ultrasonic waves, light, etc., and performs A/D.
The analog signal is converted into a digital signal by the (analog-digital) converter 12b, and the minicomputer 12 converts the analog signal into a digital signal.
G recognizes the shape configuration and generates graphic information. In other words, the -sensor 12a is substantially directly connected to the minicomputer 12c. Then, the graphic information generated by this automatic graphic input device 12 is transferred from the minicomputer 12c to the minicomputer 1 of the CAD device main body 13.
3a, and various work instructions such as modifying and adding graphic information are performed using an interactive input device 13C using a tablet or the like or a keyboard 13d. In this case, the minicomputer 13a performs graphic processing, etc., and the boss computer 13g, to which the output information of the minicomputer 13a is given via the magnetic tape 13f, generates design conditions, checks piping interference, and performs various strength calculations such as thermal stress. , performs drawing processing.

In addition, in this case, the piping model 11 is the position sensor 12a.
The system is divided into a plurality of modules 11a so that the coordinates, shapes, colors, etc. of piping, fixtures, etc. can be easily detected.

Further, the magnetic disk 13b is connected to the minicomputer 13a.
The magnetic tape 13f, which is a dedicated data bank, serves as a common data bank between the minicomputer 13a and the host computer 13Q, and also serves as an information transmission path between the two. The hard copy printer 13e is used to partially print and confirm corrections and additions to information obtained by the minicomputer 13a, as well as various work instructions. In the plotter 13h, the completed drawings 14, such as assembly and detailed drawings, based on the information generated by the host computer 13g and organized through necessary corrections, additions, etc., are sent to the printer and can be printed out as they are.

In this way, it is no longer necessary to manually create a summary, which saves working time and improves work efficiency.

In the above-mentioned embodiment, since the position sensor reads not only the position coordinates but also the color etc., the plant model 11 is provided with information only about a specific colored part corresponding to the object to be drawn. It is also possible to take it out and draw it.

Note that the present invention is not limited to the embodiments described above and shown in the drawings; for example, only the position and coordinates are read by a sensor (if the object to be drawn is clear or if the object to be drawn is determined by other means). (effective when discrimination is possible), etc., can be implemented with various modifications without changing the gist.

As described in detail above, in the present invention, in a drawing device that creates a drawing of a drawing object through computer processing based on the information of the drawing object in the plan 1 model, coordinates, shape, color, etc. are directly obtained from the plant model. At least a sensor is provided to read the coordinates and shape of the drawing target,
The purpose of the present invention is to provide a plotting device that saves time and improves work efficiency by directly inputting information on the coordinates and shape of the drawing object obtained by this sensor into a computer. It became possible.
