基于PCI总线的多功能可定制数据采集系统

摘要

为满足航空电子总线数据采集系统的通用性和多功能性,设计了基于PCI总线的多功能可定制数据采集系统；研究了相关总线板卡的驱动函数；采用自顶向下和模块化的方法设计了数据采集系统的系统运行管理模块、数据采集显示模块、数据分析处理模块和记录数据管理模块；使用了多线程、多视图、双缓存和Teechart控件等关键技术.设计实现的数据采集系统具有采集任务、ICD可定制功能,可以灵活地设计针对不同硬件的数据采集任务,效果良好.%The multifunction and customizable data gathering system based on PCI bus is designed, according to the requirements of making avionics bus data gathering system all-purpose and multifunctional. The driving function of related bus interface card is studied; the system operation management module, data acquisition display module, data analysis and processing module and recording data management module of the data gathering with top-down and modular methods are designed; the key technologies such as multithreading, multi-view, double cache and Teechart control, are used. This data gathering system has acquisition task and ICD customizable function, can be flexibly designed according to different hardware data acquisition tasks, and the result is good.
