Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0040] Such as Figure 1-Figure 4 As shown, the present embodiment discloses a method for replaying a large amount of data parameter curve based on DirectX, and the method for replaying a parameter curve includes the following steps:

[0041] S1. First, input the data collected by the collector into the computer, and draw the parameter curve through DirectX;

[0042] S2. Next, the projection mode is set to orthogonal projection, the x coordinate is set as time, the y coordinate is set as parameter value, and the drawing primitive is set as a line s...

Abstract

The invention discloses a DirectX-based large data volume parameter curve playback method, which comprises the following steps of S1, firstly, inputting data collected by a collector into a computer,and drawing a parameter curve through DirectX; s2, secondly, setting a projection mode as orthogonal projection, setting x coordinates as time and y coordinates as parameter values, and setting drawing primitives as line segment strips; s3, realizing transformation from a local coordinate system to a world coordinate system with a changeable display area through compression matrix calculation andtranslation matrix calculation; and S4, finally, arranging the plurality of parameter curves on the same panel so as to realize playback display of the parameter curves. Through tests, DirectX is utilized to realize parameter data curve playback and operation flow, curve display is smooth, and the requirement of data analysis can be met.

Description

technical field [0001] The invention relates to a method for analyzing and processing collected data, which belongs to the technical field of data collection and testing, in particular to a DirectX-based large data amount parameter curve playback method. Background technique [0002] The data curve playback display is intuitive, and it is the most commonly used method for data collection and analysis. Due to the improvement of the performance of the collector, the amount of parameter recording data is getting larger and larger. Taking the collection frequency as 50Hz as an example, the number of data collected in 2 hours will reach 7200. The collection frequency of high-performance collectors can even reach MHz or even GHz, and the corresponding collection data volume will reach millions or even more per second. [0003] If such a huge amount of data is used, ordinary drawing software such as Matlab (matrix work) or GDI (graphics device interface) will cause the program to...
