Automatic segmentation method for 1553B servo instruction of solid engine test

Abstract

The invention provides an automatic segmentation method for a 1553B servo instruction of solid engine test. A test data record file is opened, a sinusoidal signal is marked as 0, two adjacent data points are read sequentially and whether the two data points are equivalent is determined, and if the two data joints are not equivalent and the sinusoidal signal is marked as 0, it is determined that first data of the group of the data is a first data point of the sinusoidal signal of certain frequency point, a corresponding time stamp is recorded, and the sine is marked as 1; and if the two data joints are equivalent and the sinusoidal signal is marked as 1, it is determined that the first data of the group of the data is an ending data point of the sinusoidal signal of certain frequency point,a corresponding time stamp is recorded, and the sine is marked as 0. A time stamp array composed of an even number of time stamps is obtained finally. The first and second time stamps represent startand end time of the sinusoidal signal of the first frequency point respectively, the third and fourth represent start and end time of the sinusoidal signal of the second frequency point respectively,and the rest can be done in the same way; and the start and end time of the sinusoidal signals of all frequency points can be obtained, and thus, data of the test data file is segmented according tothe start and end time of the sinusoidal signals of all frequency points.

Description

technical field [0001] The invention relates to the technical field of solid engine ground test measurement and control, in particular to a method for automatic segmenting of solid engine test 1553B servo commands. Background technique [0002] Servo system is a control system widely used in industry, aviation, military and other fields, and its frequency characteristic is one of the most important system characteristics. The principle of servo system frequency characteristics test is relatively simple. The test signal is input into the servo system under test, and the input and output signals are collected into the computer, and the corresponding algorithm is processed to obtain the frequency characteristics of the servo system. The performance of the servo system must be verified through a ground test run with the engine. In the ground joint test of the solid engine, the ground servo system sends the servo mechanism action command to the servo controller on the missile thr...
