面向实时控制任务的高速数据采集存储方法

Method of high-speed data acquisition and storage for real-time system control

提出一种基于CAN总线,面向实时控制任务的高速数据采集存储方法.该方法将数据实时采集、系统实时控制、数据存储与显示分配在相互独立的处理单元中实现,处理单元之间通过独立的CAN网络进行通信.该数据采集方法解决了数据实时采集与系统实时控制之间的矛盾.利用队列技术,该方法解决了数据存储与数据实时显示之间的矛盾.该数据采集存储方法已成功应用到某大型仿真系统中.

A method of high-speed data acquisition and storage for real-time system control is proposed,based on CAN bus.In the proposed method,the functions of real-time data acquisition,real-time system control,data storage and display are implemented on independent processors.The communications between the processors are realized via independent CAN bus networks.This method not only deal with the relationship between real-time data acquisition and real-time system control,but also deal with the relationship between...
