一种高速实时多任务数据采集系统设计

A New Design of High-speed Multi-task Real-time Data Acquisition System

针对实时多任务数据采集系统的任务调度和时间调度提出了自己的实现策略,给出了一种基于ARM9(S3C2440A)和μC/OS-II操作系统平台的实时多任务数据采集系统的设计实现方法;在满足实时多任务数据采集系统对实时性和快速性要求的基础上,实现了数据的多通道实时并行采集和单通道实时采集,并对μC/OS-II操作系统进行了适应性改造,对出厂Bug进行了修正。

This paper introducers a task and time scheduling strategy for real-time data acquisition systems,and give a method towards design and realization of real-time data acquisition systems which based on ARM9（S3C2440A） and μC/OS-II Operating system.Achieved data acquisition in real-tine model and single-channel model,on the base of fulfilling the requirements of real-time and rapidity in the real-time data acquisition system.And reformed the μC/OS-II real-time kernel and Bug in factory process in order to meet the needs of actual demand.
