飞机灯光告警系统自动测试设备研制

Design of Auto Test Equipment for Plane Light Alarm System

告警控制盒是飞机灯光告警系统的核心部件,采集来自飞机各系统的告警信号,经分析处理后控制信号灯盒点亮、熄灭与闪烁来表达不同的告警信息。对告警控制盒进行了测试需求分析,基于ATE硬件平台设计了自动测试电路,采用了总线程控仪器和图形化测试软件等技术,实现了告警控制盒的功能和性能自动测试。经部队使用表明,该设备具有测试效率高、人机交互界面友好和操作简单等优点。

The alarm control box as the key part of plane light alarm system is used to express different alarm information by controlling sig-nal light boxes to light on, light off or flicker. The test source requirements of the alarm control box are introduced in detail and the design of test circuit for the alarm control box based on ATE hardware platform is also given. Some technologies such as bus program controlling instruments and GUI test software are applied to realize functions verification. The equipment performance is validated by the army in the following respects： grea-ter efficiency, easy to operate and friendly graphical user interface.
