Water information engineering design?

1 Significance of hydraulic engineering design

In the process of water conservancy project design, information technology and new technology are actively used to give full play to the role of information technology in water conservancy project design, which can complete the project design with high speed and high quality, provide reliable technical scheme for the implementation of water conservancy project and implement it smoothly [1].

2 Application of information technology and new technology in water conservancy project design

2. Application of1AutoCAD technology in hydraulic engineering design

AutoCAD is a technology imported from America and a popular drawing tool in the world. It can not only draw two-dimensional and three-dimensional graphics, but also has a fast drawing speed. With the development of information technology, AutoCAD technology has been widely recognized and is a compulsory technology for designers and draftsmen. In the concrete design of water conservancy projects, it is necessary to draw a large number of design drawings such as floor plans and structural drawings. AutoCAD technology can improve the drawing speed and make the drawing simple and convenient. When applying AutoCAD technology in hydraulic engineering design, we should pay attention to the following aspects:

2. 1. 1 Design system variables

In general, it is not necessary to modify the system variables, but sometimes there are special requirements in the design process of specific water conservancy projects, and the system variables need to be reset. In this process, it is very important to master the function and usage of some commonly used variables, which can improve the efficiency of designing system variables. In engineering drawing, text is also an indispensable part. We should systematically understand the notes, explanations and annotations in design drawings, and skillfully master their application methods and precautions, so as to accurately express the ideas of water conservancy engineering design through these words and figures [2].

2. 1.2 multi-layer display

A layer is a transparent overlay for organizing related information. Each hydraulic engineering design layer contains information such as graphics, text and images. In order to have a better display effect, they need to be superimposed. To facilitate the management of layers, you can use VCL components to manage them. VCL component is a component dedicated to managing multiple layers. It has a visual environment, can encapsulate Windows windows and distribute messages, and can arrange layers in a certain logical order, which is convenient for managing multiple layers.

2. 1.3 design scheme inspection

In the design scheme audit stage, the 3D rendering technology in AutoCAD is mainly used to audit the design scheme of water conservancy project. Three-dimensional human body structure can be drawn by using the three-dimensional rendering technology in AutoCAD. You can draw three-dimensional renderings first and then render them. Three-dimensional rendering technology mainly makes the graphics more beautiful and more harmonious with the surrounding environment by adding materials, shielding light sources, shielding shadows and other means.

2.2 the practical application of AutoCAD

The concrete application example of AutoCAD in water conservancy design: drawing dam surface curve. In the process of drawing dam surface curve, spline command in Au-toCAD software and office tools such as EXCEL can be used to realize it. Use EXCEL to process related data information, and then convert the data into a specific coordinate form. Then execute the spline command in AutoCAD, copy the curve coordinates in EXCEL, paste them into AutoCAD, and press Enter to end the drawing process. In the process of converting data into coordinates, the conversion process can be realized through the conversion table in the following figure, and then the coordinate points of drawing curves can be determined according to the specific construction data in water conservancy construction projects, such as water level, storage capacity and other data, combined with the table calculation function in AutoCAD coordinate conversion process technology. The specific implementation process is as follows: ① draw a table in AutoCAD and input relevant data into the table; ② The specific storage capacity should be calculated by using the table calculation function in Auto-CAD software; ③ Input of relative coordinates; (4) Change the water level difference of each coordinate point. Because the water level is far from the storage capacity, the water level difference in the coordinates should be enlarged by 5 times. In the process of adjusting related values, the function of related coordinate points should also be marked, and the position on the curve relative to the origin of coordinates should be marked. In the process of calculation, it should be noted that the specific water level value is obtained by dividing the numerical value in the coordinates by the corresponding multiple; ⑤ Execute UCS command in AutoCAD; ⑥ Execute spline command in Auto-CAD, draw related spline curves, and input coordinates after adjustment; ⑦ Press Enter to end the curve drawing process and complete the drawing of water level-storage capacity curve.

2.3 application of SV 300 surveying and mapping software in water conservancy project design

SV300 surveying and mapping software is a set of professional intelligent surveying and mapping software, through which the data in hydraulic engineering design can be systematically processed, and it has the functions of drawing and management. SV300 surveying and mapping software is based on AutoCAD software and combined with the interactive graphic processing interface of Micsoft-windows, which has a very convenient and quick graphic drawing function. The application of SV300 surveying and mapping software in hydraulic engineering design is shown in the following aspects:

2.3. 1 image calibration

Using the graphic calibration function in SV300 software in hydraulic engineering design can solve the problem of angle deviation in traditional graphic processing well. Taking a 500m×500m topographic map as an example, if you want to generate an image of 1∶ 1000, you can follow the following four steps: ① Select a calibration point. Will it be 2 colors *? Transfer the bmp file to the image calibration program in SV300 software, and select four corners of the image as calibration points, or select calibration points within the graph to improve the accuracy; ② Enter the calibration point. The process of calibration point input is as follows: click the image in the edit drop-down menu, then click pixel acquisition, change the diagonal point in the dialog box, enter four pixel values (0,0) (3000,0) (0,3000) (3000,3000) and exit; ③ generate a standard orthogonal image; (4) adjust the proportion. Select Edit from the drop-down menu, click Image and Pixel Acquisition in turn, and enter the coordinates of the lower left corner and the upper right corner in the Pixel Acquisition dialog box, that is, (0,0) and (500,500), to generate an image with a scale of 1: 1000.

Overlay function

SV300 software also has shielding function. Can maintain the integrity of the contour line, highlight the text, cover the contour line and other functions. This function can highlight the structure in the graph, maintain the integrity of the entity, and is also beneficial to editing.

3 Conclusion

In addition to the above two kinds of information processing software and technologies, there are many information technology means and new technologies that can be applied to hydraulic engineering design, such as FAHP technology, AutoCAD software and office software. These technologies can play an important role in the design of water conservancy projects, and need to be flexibly selected and applied according to specific construction objectives and conditions.
