基于DSP的嵌入式网络化数据采集分析系统

System on Real-time Data Acquisition and Signal Processing System Based on Internet/Intranet Oriented DSP and Embedded Technologies

为了实现网络通讯和远程诊断,提出了一种基于网络的嵌入式现场实时信号采集分析系统的总体方案及软硬件系统实现模式．从网络控制管理、数据处理部分设计及其接口和协同工作等角度研究了一个网络化数据采集平台的设计和实现,通过采用ARM和DSP主从处理器结构、嵌入式LINUX系统及合理的多任务分配机制,保证了系统的实时性要求,将网络数据传输率需求控制在可行范围内．

To realize net-based real-time communication and long distance diagnose, an embedded main architecture of real-time data acquisition and signal processing system based on TCP/IP is proposed and analyzed. And design and realization of the data communication system, which is based on Internet/Intranets including master CPU （ARM） of net managing, slave CPU （DSP） of data processing and their interface both in software and hardware are also presented. By using ARM and DSP master-slave system, embedded LINUX OS and reasonable multi-task-assigned mechanism, the demand for real-time and data communication speed of network are guaranteed.
