某型飞机武器控制系统执行组件测试仪

Test equipment for Executing Componentin a Certain Airborne Weapon Control System

摘要:

某型飞机武器控制系统执行组件测试设备在测试诊断过程中，操作复杂且需人工排除故障，因此测试诊断效率低下。为了提高测试诊断效率，设计了某型飞机武器控制系统执行组件测试仪。首先，基于执行组件接口信号分析，获得测试需求，设计了执行组件测试仪的系统结构和工作原理；然后，搭建了以STC89C51单片机为控制核心，具有8路开关量输入和输出功能的硬件电路，并且在Keil编程环境下采用C语言开发了包含测试和诊断模块的系统软件；最后，采用多路测试技术和故障字典法，设置执行组件故障，并通过测试仪的按键控制模块模拟所有可能的测试情况，验证了执行组件测试仪的有效性。实际使用表明，该测试仪可自动故障定位到元器件级，有效提高测试诊断效率。

Abstract:

In the process of test and diagnosis, the test equipment for execution component in a certain airborne weapon control system needs complex operation and manual troubleshooting, so the efficiency of test and diagnosis is low. To improve test efficiency, a new test equipment for executing component in a certain airborne weapon control system is designed. First, According to the test requirement based on the relationship with input and output of the executing component, The system structure and working principle of the test equipment are designed. Then, The circuit of test system based on STC89C51 microcontroller which has the function of receiving and sending eight-channel switching signal is built. and the software baed on keil development environment for the STC89C51 microcontroller is designed wih C-language, which contains test and diagnostic modules. Last, The multi-channel test technology and fault dictionary method are used, the execution component failures are set, and all possible test conditions through the key control module of the test equipment are simulated. All of above verify the validity of the test equipment. The practical application shows that the test equipment can automatically locate faults to the component level and effectively improve the efficiency of test and diagnosis.
