6A系统综合试验台系统设计与实现

Design and Implementation of Integrated Test-bed for 6A System

从机车车载安全防护系统(简称6A系统)检修现场运用实际需求出发,基于QNX操作系统,设计了用于检测6A系统中央处理平台、各子系统板卡以及外围传感器的6A系统综合试验台,阐述了6A系统综合试验台系统的总体方案设计,详细介绍了各检测模块检测原理以及系统软件设计与实现,概述了6A系统综合试验台的测试内容。实际应用结果表明,6A系统综合试验台具有很高的自动化水平和现场实用性。

According to the actual testing needs of the locomotive safety protection system （abbreviation： 6A）, based on QNX operating system, an integrated test-bed is designed in this paper, which is used for the testing of the central processing platform, the child sys- tem boards and peripheral sensors of 6A system. The overall design of the system is expounded, including the principle and the soft- ware design and implementation of testing modules. The test content of the integrated test-bed is introduced. Practical implementation has proved that the integrated test-bed has a high level of automation and practicability.
