Embodiment Construction

[0047] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0048] 1. First explain the following concepts:

[0049] a. In grayscale graphics, the operating system uses 0-255 to represent the color that gradually transitions from black to white;

[0050]b. The graphics read into the computing system are bitmap graphics, that is, the graphics are divided into several small squares, each small square is called a pixel point, and the grid composed of these pixel points is called " Grating". The computer expresses the entire graphic by expressing information such as the position, color, and brightness of these pixels;

[0051] c. The matrix serial number is the serial number of the data in the matrix, such as matrix

[0052] , the matrix numbers 1 to 6 are test(1) to test(6), and their values ​​are a, b, c, d, e, f respectively.

[0053] 2. The computing system reads in the bitmap graphics to be analyzed, such as figu...

Abstract

The invention discloses a method for fast reading a cross electrical parameter graph. The method comprises the following steps of reading a bitmap graph to be analyzed in an operating system, inputting the X-axis coordinate range X of the graph, the Y-axis coordinate range Y of the graph and the curve number Z in the graph, transforming the graph in a matrix mode, removing transverse and vertical grid lines, arranging the graph, determining the function relationship between x0 of the X axis and y0 of the Y axis within the certain X-axis coordinate range and the Y-axis coordinate range according to a matrix value of the obtained arrangement graph, wherein the function relationship meets a formula that y0 is equal to f(x0), and using the function relationship in calculation in actual work. The method can carry out quantitative analysis on the electrical parameter graph with a high speed and an accurate rate, the determined function relationship brings convenience to use and calculation, and effective data can be provided for normal proceeding of follow-up design development work.

Description

technical field [0001] The invention belongs to the field of electrical product design, and in particular relates to a method for quickly reading cross electrical parameter graphs, which is used to quickly read electrical parameter graphs, improve the accuracy and accuracy of reading parameters, and facilitate electrical engineers to compare similar components parameters, select the appropriate model, and optimize product design and development. Background technique [0002] With the increasing popularity and widespread use of automobiles, the economy and energy saving of automobiles have been paid more and more attention. In the process of vehicle design, how to accurately select models to avoid over-design has become an issue that car planning, design, and sales personnel are increasingly concerned about. [0003] As an OEM, in order to meet market demand, it is necessary to continuously design new models and optimize old models to increase market share, while improving p...
