航空瞄准显示设备是战斗机武器系统的重要组成部分,对其性能的检查测试研究十分必要。嵌入式PC由于功能扩展性强、体积轻便已经成为测试设备的主要搭建平台,文中设计了一种基于技术成熟的PC/104总线计算机测试平台的外场检测系统,能实现对机载设备信号的原位检测。根据航空瞄准显示设备测试需求,在多种方案中比较优选,制定出软、硬件结合的设计方案,并介绍了采用的主要技术手段。本系统的开发和应用,为提高装备的维修保障能力提供了一种有效手段,也为类似检测设备的设计提供一种有效的方法。 Aviation aiming display device is an important part of the fighter weapon system. It is very necessary to inspect its performance. Embedded PC has become the main platform for testing equipment due to its strong function expansion and light weight. In this paper, an outfield detection system based on the mature PC / 104 bus computer testing platform is designed, which can realize the original Bit detection. According to the test requirements of aviation aiming display equipment, it is more preferable in a variety of schemes to formulate a design scheme combining hardware and software and introduces the main technical means adopted. The development and application of the system provide an effective means to improve the maintenance and repair capability of equipment and provide an effective method for the design of similar testing equipment.
