摘要
在许多恶劣的环境下,测量者不能长期置身其中,使得数据采集和传送变得非常困难。为了解决这一问题,设计了一种基于SOPC的远程数据采集系统。以Nios II软核处理器和所需的外设IP核嵌入到FPGA中为硬件架构,以移植μC/OS-Ⅱ实时操作系统和TCP/IP协议为软件体系,实现了开放式可重构的软硬件体系结构。通过对温湿度采集,表明该系统能够满足高速采集数据的实时性和同步性要求,具有广泛的适用性和良好的应用前景。
Data gathering and convection is difficult,because the measurer can t live in all kinds of execrable condition long.For resolving the problem,design a remote data gathering system based on SOPC.In this device,the Nios II soft CPU core and peripheral s IP core is embedded in FPGA,the μC /OSII real-time operating system and TCP/IP protocol stack is replanted in it,a open system is achieved which hardware and software can be reconfigure.The system realizes temperature and humidity gathering,which indicates that it satisfies data gathering system in real - time and in - phase. This device has fine applicability and application prospect.
