Structural design of a universalized carrier rocket test system

Abstract

The invention discloses a structural of a universalized carrier rocket test system. The system structure is suitable for design of an automatic testing system of a multi-type carrier rocket in China.The designed universalized carrier rocket test system structure comprises a hybrid test framework constructed based on C / S (Client / Sever) and B / S (Browser / Sever), A networked distributed test system constructed based on LXI, PXI and other bus instruments is a new generation of spaceflight automatic test system software architecture constructed based on international advanced ABBET standards. The carrier rocket automatic test system is small in size, high in test efficiency, good in interactivity, high in safety and reliability, good in adaptability, high in timing and synchronizing capacity, high in transmission speed and high in compatibility, and a design method high in universality and low in cost is provided for a new generation of carrier rocket automatic test system.

Description

technical field [0001] The invention belongs to the field of automatic testing, and is a generalized launch vehicle testing system structure design. Background technique [0002] The development of launch vehicle automatic test launch control technology develops along with the development of launch vehicle. Abroad, space vehicle testing technology is represented by the United States and the European Space Agency. Early American launch vehicles did not adopt standard processing, procedures, support equipment or infrastructure. Each set of test equipment was highly targeted and specific, and each mission was independent, with very poor versatility. The cost is very expensive. Therefore, from the late 1960s, the United States began to consider "three modernizations" (modularization, combination, and generalization) in testing technology. Over the years, the realization of "three modernizations" has brought great benefits to the testing of American aerospace vehicles [Yu Jins...

AI Technical Summary

Problems solved by technology

[0007] (1) Aerospace equipment lacks sufficient testability design: due to insufficient testability design in the design stage of the equipment, it is difficult to select the measured points of the equipment in the test stage, which in turn brings inconvenience to the smooth development of the test work;

[0008] (2) Poor versatility: due to the lack of unified ATS specifications and standards, most products have not gotten rid of the one-to-one mode between the object under test and the test equipment so far, and the utilization rate of test resources is low;

[0009] (3) Poor compatibility: my country's aerospace testing has a long history, and a large number of automatic testing systems have been produced in this process. These systems are mainly based on a single bus-type instrument (such as GPIB, VXI, etc.). The devices are not compatible with each other;

[0010] (4) Low utilization rate of test and diagnosis information: test data is stored in the form of files in text or binary content format, which brings great difficulties to data query, analysis, comparison, etc.;

[0011] (5) The degree of industrialization of test products is low: in the aerospace test systems currently equipped in China, most of the test equipment are foreign products, and the localization rate is low
