摘　　要：飞机音频管理系统检测中一方面要模拟、测量与之存在交联的来自机载导航和通信设备的信号,且测试项目、信号种类和数量繁多;另一方面,还要控制和监视专用试验平台模拟机载运行环境以便音频管理系统故障复现,因此基于LXI总线的自动测试系统构建方案成为最佳选择。在软件开发中,通过分析被测对象的测试需求和测试过程,提出面向对象的模块化软件开发方法,大大提高了软件复用性和开发效率。实践证明,采用LXI总线提高了自动测试系统的可靠性,缩短了航修公司的维修时间,降低了维修成本,提高了维修效率。In the detection of civil plane audio management system, it must to simulate and measure the cross-linked signals which come from the airborne navigation and communication equipment, and the test items, the type and quantity of the signal are so many;On the other hand, it must control and surveillance the special test-bed simulate the airborne operating environment in order to audio management system fault recur, so based on the LXI bus build the automatic test system to be the best selection. In the software development, through analyze the test requirements and testing process of the measured object, advance the modular object-oriented software development methods improve the software reusability and development efficiency greatly. Practice has proved that the use of LXI bus improve the automatic test system reliability, shorten the aircraft repair company repair time, reduce maintenance costs and im- prove the efficiency of repair.
