某型飞机航行驾驶综合体的数据集成技术

The study for data integration technology of avionics integrated system

介绍了高通用性的航行驾驶综合体总线检测仪的研究,并详细描述了该检测仪相关功能模块、硬件的设计原理:在硬件上采用带CPU-双向RAM的数据采集卡;利用数据集成、多总线测试与信息分析技术,基于VB开发出通用检测软件,实现对航行驾驶综合体多个子系统总线信息的快速采集、精确化显示;创建故障诊断数据库,自动调入采集数据,分析、定位故障,可对多个系统进行故障测定,提高了检测设备的通用性和性价比。

Design a multi - airbus testing system of avionics integrated system, using the data acquisition card with CPU and double -RAM, where data can be wrote in by the card and read by the testing program. Based on data integration and processing technology, setup the auto -connection between the model of data processing and malfunction diagnosis database, so the malfunction of all the sub - systems can be found quickly ; the design features of data acquisition card, data processing modle and malfunction diagnosis database is proposed.
