Problems solved by technology
At present, the display and viewing of balance readings in domestic wind tunnel tests all use a single color to display a single color balance reading, such as displaying a black balance reading on a white background color, to view when the number of balances and balance components are small. It is still easy to compare, but when the number of balances and the number of balance components are large, it is particularly difficult to quickly distinguish, view, and compare during the test; and the operator stares at the monotonous black and white for a long time. It is easy to make the observer's eyes tired and distracted, which leads to errors in data classification and identification

Embodiment Construction
[0019] The method of the present invention comprises the following steps:
[0020] A. Define m kinds of basic colors, marked as Basic_color(n), n=1,...m, and the value of m is 5-10;
[0021] B. Before the test, define the balance identifier in the form of "B + balance number j + balance component name";
[0022] C. During the test, the balance identifiers are read sequentially, and the balance number j is automatically resolved;
[0023] D. Substitute the balance number j into the calculation formula (1) to calculate the background color value of the balance reading, and record it in the color array;
[0024] E. When displaying the balance reading, first set the background color of the balance reading display area according to the data in the color array, and then display the black balance reading.
[0025] Wherein, the m primary colors described in step A are m constants, which are used to represent the color values that need to be subtracted from white. In order to faci...

The invention provides a method for displaying balance readings in separate colors in a wind tunnel test. The method includes the following steps: firstly based on identifiers of balances, automatically identifying which balance does each balance reading belong to, then based on identification results, displaying the balance reading in different background colors in accordance with the classification of the balances. The method enables operation workers to identify and look up data in accordance with balance identifiers and to directly identify classification and look up the data based on colors. The application of a plurality of soft colors can also effectively alleviate vision fatigue of the operation workers. The method can automatically display the balance readings in the wind tunnel test in separate background colors in accordance with balance numbers, such that viewers can rapidly classify, identify and compare data through colors, and also the application of a plurality of soft colors can effectively alleviate vision fatigue of the operation workers.
Description
technical field [0001] The invention belongs to the technical field of aerodynamic wind tunnel tests in the aerospace industry, and relates to a method for displaying balance readings in wind tunnel tests. Background technique [0002] As an important part of experimental aerodynamics, one of the main tasks of the wind tunnel test is to use the balance to measure the force and moment felt by the aircraft model. During the test, a large number of balance readings need to be displayed, viewed, compared and analyzed. At present, the balance readings in domestic wind tunnel tests are displayed on a single background color. For example, black balance readings are displayed on a white background. When the number of balances and balance components are small, check, It is still easy to compare, but when the number of balances and the number of balance components are large, it is particularly difficult to quickly distinguish, view, and compare during the test; and the operator stares...
