摘　　要：近年来航空武器的功能性能快速提高,机载计算机处理能力也越来越强;接口模块作为处理多种接口信号的重要部件,在机载计算机中起着至关重要的作用;文中结合故障注入技术,在以往常用模拟量采集电路基础上,设计了模拟量激励产生电路,实现模拟量采集电路的故障注入,结合测试软件完成模拟量采集电路的检测,达到提高机载计算机的测试性的目标。In recent years, The function and performance of aviation weapon is increasing rapidly, Airborne computer processing ability is also becoming stronger. As an important part of processing multiple interface signals, Interface module plays a vital role in airborne computer. Based on the fault injection technology and the widely used analog signal acquisition circuit, Designed the analog signal generating circuit to injection fault for analog signal acquisition circuit, with the test software to complete the detection of the analog signal acquisition circuit, so as to improve the test performance of the airborne computer.
