An Aircraft Integrated Test System Based on 1553b Bus

Abstract

An air vehicle integrated testing system based on a 1553B bus comprises a power distribution conversion module, a direct-current power source, a direct-current power source controller, an alternating-current power source, an alternating-current power source controller, a measurement and control computer, a bus controller, a testing interface adapter, a bus protocol conversion module, an AD collecting module, a digital multimeter, a testing control module, a signal conditioning module and a data interpretation module. Related equipment in a traditional air vehicle testing scheme is integrated sufficiently to form a highly integrated general testing platform, and ground testing for an air vehicle achieves integration, miniaturization and portability assisted by advanced software technologies.

Description

technical field [0001] The invention relates to an aircraft integrated test system based on a 1553B bus, which is suitable for verifying the parameter characteristics of the avionics system during the ground test of the aerospace / aviation aircraft before leaving the factory. Background technique [0002] At present, the traditional distributed test technology is widely used in the ground test system of the domestic aviation / space vehicle before leaving the factory, which is used for the internal function and performance test of different systems. [0003] Aviation / aerospace vehicle distributed test technology refers to the difference between different subsystems, such as the power supply and power distribution subsystem, navigation guidance and control subsystem, measurement and control communication subsystem, data and health management subsystem under the same avionics system. It has a set of independent ground test equipment, which independently completes the functions of...

AI Technical Summary

Problems solved by technology

At present, with the continuous improvement of test requirements for aircraft avionics systems, the defects of distributed test schemes, duplication of test equipment functions, and poor comprehensive utilization have become more and more obvious. Inconsistent standards lead to poor compatibility and low reliability of the entire system, and the maintenance of test equipment requires a lot of manpower and material resources, resulting in a lot of waste of resources

Secondly, due to the large number of equipment in the test site of each subsystem, the layout of cables in the site is often chaotic, the command of personnel is not in place, the test process and status are not clear, it is very easy to cause misoperation by test personnel, the number of test repetitions is large, and it is difficult to find errors, etc. question

[0004] With the increase of aircraft development tasks, the accumulation of a large amount of experience of designers, the vigorous development of network technology, the continuous innovation of bus test technology, and the urgent need for new test technology, the traditional distributed ground test technology can no longer adapt to the current aviation environment. / Space Vehicle Test Requirements
