基于共享内存的实时数据保存系统研究

详细介绍了基于共享内存的半实物实时仿真平台中数据保存系统的设计思路、工作原理和关键技术。通过对WindowsNT操作系统线程调度和中断响应的实时性改造和”中断驱动读取数据一数据缓冲暂存数据一多线程保存数据”软件架构的优化设计，改善了WindowsNT下中断响应和线程调度的实时性和确定性性能，实现了多节点、任意数据量的同时保存，为半实物实时仿真系统有效工作打下了基础。

Research on Real-time Data Saving System Based on Shared Memory

This paper describes the design idea, operating principle and key technology of the data saving system based on shared memory in the real-time hardware-in-the-loop simulation platform. By improving the real time performance of thread scheduling and interrupt respome of WindowsNT and optimizing the ＂interrupt-drive reading data-data-buffer registering data-multi-thread saving data＂ software frame, the real time performance and divinable performance of interrupt response or thread scheduling based on WindowsNT are improved and data quantity from multi-node could be simultaneous saved in time. At present, this data saving system has come on the line.
