A system for drawing schematic diagrams based on android platform

Abstract

The invention discloses a point schematic drawing system based on an android platform, comprising: an engine module for building a technical framework and providing a technical engine for the point schematic drawing system; a determination module connected with the engine module for Based on the user's use method to determine the entrance of the schematic drawing of the entry point; the collection module is connected to the determination module, and is used to collect the user's gesture touch event after the determination module determines the entrance of the schematic drawing of the entry point; draw module, connected to the collection module, for drawing a point diagram according to the gesture touch event; a storage module, connected to the drawing module, for drawing the completed point diagram after completing the drawing of the point diagram The schematic diagram is output and converted into multiple format files for storage, which makes drawing point schematic diagrams more convenient and improves user experience.

Description

technical field [0001] The invention relates to the technical field of graphic drawing, in particular to a system for drawing schematic diagrams of points based on an android platform. Background technique [0002] At present, we are in the tide of the information age. All walks of life have widely applied information technology. Of course, the testing industry is no exception. In the testing field, testing agencies usually need to send professional sampling personnel to the sampling point to conduct environmental inspection Sampling, and it is necessary to describe the orientation, wind direction, distribution and other information of the sampling points. In the traditional sampling task, the sampling personnel manually draw the schematic diagram on paper, but in the case of complex and changeable terrain environment, the manual drawn schematic diagram is inevitably not convenient and accurate, and once the drawing is wrong, the drawn content on the paper needs to be Smudg...

Problems solved by technology

In the traditional sampling task, the sampling personnel manually draw the schematic diagram on paper, but in the case of complex and changeable terrain environment, the manual drawn schematic diagram is inevitably not convenient and accurate, and once the drawing is wrong, the drawn content on the paper needs to be Smudge or simply redraw, so that the hand-drawn schematic diagram is even more unreliable, so an electronic drawing tool is particularly important

[0003] Thanks to the rapid development of electronic technology, now samplers only need to carry a very portable mobile device such as a tablet or mobile phone to work anywhere, but there is no effective solution for such application scenarios that require drawing. The reason is that the current professional drawing tools on the market are basically concentrated on the PC side. Limited by the screen size and operation methods on the mobile device, it is difficult to have the same operating experience as the PC side on the mobile device. Drawing tools only focus on non-industrial scenes such as retouching, painting, graffiti, sketching, etc., and cannot draw or easily draw graphic elements such as second-order Bezier curves, parallel lines, polyline arrows, concentric circles, and wind directions in industrial scenes; It is also impossible to readjust the previously drawn content during the drawing process; the most important thing is that there is no concept of source files and multi-layers, which is almost impossible for the need to open the edit adjustment again after temporary saving

[0004] Specifically, there are the following technical problems in the existing technology: (1) There is no concept of source files; the drawn content is directly output as a picture at one time, which directly affects the need for temporary storage and subsequent repeated adjustments

(2), there is no concept of multi-layer

Due to the small screen size of mobile devices, and most of them are drawn with fingers, once the drawn content is too much, and you want to adjust the drawn content, such as modifying the color, dragging the size, etc., it will be difficult to select it by clicking with your finger Correct graphic elements, it is easy to accidentally touch other graphic elements, which also indirectly affects the need for repeated adjustments

(3) There is no copy function; it is very useful when many identical graphics need to be drawn, and the same graphics cannot be drawn quickly;

[0005] (4) Graphical elements are not rich enough; point diagrams often need to be drawn with some fixed graphics, such as concentric circles, parallel lines, Bezier curves, etc., but the current mobile terminal drawing tools do not provide these dedicated graphics

(5) The unity of graphic elements. During the drawing process, it is often necessary to draw multiple identical graphic elements as the representation of the same type of elements. However, due to the lack of a suitable size control mechanism, the drawn elements are prone to inconsistent sizes. Problems affecting the aesthetics and professionalism of schematic diagrams

(6) There is no auxiliary line; during the drawing process, there is no grid auxiliary line that causes the drawn elements to be arranged differently. At the same time, there is no control point auxiliary line, so that the touch position cannot be accurately known when the gesture is dragged
