【摘要】：随着自动测试技术的不断发展,军用自动测试设备已经成为武器装备的重要组成部分,自动测试系统是武器装备维护过程中的必要手段,也是武器装备战斗力的有力保障,对提高部队装备水平和作战能力具有重要意义。本文以某通信干扰飞机的任务系统为测试对象,在详细分析侦察引导子系统测试需求的基础上,提出了综合自动测试系统的总体设计方案。该综合自动测试系统包括自动测试设备(ATE)、测试程序集(TPS)和自动测试系统软件平台。ATE由PXI总线模块仪器、GPIB台式仪器,以及系统控制单元、信号阵列接口等组成;TPS由测试适配器(TUA)、测试程序、测试说明文档组成;自动测试系统软件平台能够完成系统配置、测试程序开发、测试程序运行。测试适配器是连接ATE与被测设备(UUT)之间的桥梁,本项目共设计完成7个适配器,其中6个用于测试、1个用于系统校验。为了满足测试设备通用性和标准化的要求、以及降低测试设备成本,适配器采用可拆卸式。本文重点针对某频段侦察引导子系统设计了测试适配器,该适配器提供了SPI、RS232、RS422、ARINC429、LAN、KVM等通信接口,并能够满足13个单机设备的测试。测试程序是基于自动测试系统软件平台GPTS3.1开发的,GPTS3.1为通用测试软件平台,采用面向信号的测试过程描述语言ATLAS作为编程语言,该平台能够实现测试程序与系统仪器无关性设计。每个UUT对应一个测试程序,在测试程序中,每个被测项目定义成一个章节,本文设计完成了4个测试程序,共24个章节。本文以射频接收前端的测试为例,在详细介绍其组成模块测试内容以及测试方法的基础上,对接收灵敏度的故障隔离、故障定位方法、以及测试步骤进行了说明,并详细分析了故障原因。测试充分表明测试适配器、测试程序稳定可靠,测试结果准确可信,效率高,故障检出率高,故障隔离准确。
[Abstract]:With the continuous development of automatic test technology, military automatic test equipment has become an important part of weapon equipment. Automatic test system is a necessary means in the process of weapon equipment maintenance, and it is also a powerful guarantee of weapon equipment combat effectiveness. It is of great significance to improve the equipment level and combat capability of troops. This paper takes the mission system of a communication jamming aircraft as the test object and puts forward the overall design scheme of the integrated automatic test system based on the detailed analysis of the test requirements of the reconnaissance and guidance subsystem. The integrated automatic test system includes automatic test equipment (ATE), test assembly (TPS) and automatic test system software platform. Ate is composed of PXI bus module instrument GPIb desktop instrument and system control unit. Signal array interface is composed of test adapter (TUA), test program, test description document, automatic test system software platform can complete system configuration, test program development, test program running. The test adapter is a bridge between ATE and (UUT). This project designs 7 adapters, 6 of which are used for testing and 1 for system verification. In order to meet the requirements of generality and standardization of test equipment and reduce the cost of test equipment, the adapter adopts detachable type. This paper focuses on the design of a test adapter for the reconnaissance and guidance subsystem in a certain frequency band. The adapter provides communication interfaces such as SPIRS232, ARINC429ARINC429LANU KVM, and can meet the test of 13 single equipment. The test program is based on GPTS3.1, an automatic test system software platform, which is a general testing software platform. It uses signal-oriented test process description language (ATLAS) as the programming language. The platform can realize the design of the test program independent of the system instrument. Each UUT corresponds to a test program. In the test program, each item under test is defined as a chapter. In this paper, four test programs have been designed and completed, with a total of 24 chapters. Taking the RF receiver front-end test as an example, this paper describes the fault isolation, fault location method and test steps of the receiving sensitivity on the basis of the detailed introduction of the test contents and test methods of its component modules. The fault causes are analyzed in detail. The test results show that the test adapter is stable and reliable, the test results are accurate and reliable, the efficiency is high, the fault detection rate is high, and the fault isolation is accurate.
