摘　　要：分析了AFDX(avionics full duplex switched Ethernet)高速数据采集记录系统的需求,设计了系统的执行流程,确定了系统的模块组成,介绍了各模块的实现方案。利用多线程、循环缓冲区等技术,实现AFDX总线高速长时间无故障数据采集。该数据采集记录系统采用MFC实现,并利用了TeeChart控件。After analyzing the demands of high speed data acquisition and recording system on AFDX, the exe- cution process of system is designed and the module components of this system are determined. The implemen- tation methods of the modules which constitutes the system are described. Long time high-speed trouble-free data acquisition are achieved for the AFDX with the usage of technologies such as multi-thread and circular buffer. The system is implemented by using MFC and the TeeChart controls.
