基于DSP嵌入式系统的网络接口设计

首先针对一个具体测控系统的网络化改进,通过分析现有系统拓扑结构在控制方式上存在的缺陷,提出用嵌入式系统及分布式控制方式取代传统的中央控制结构方案,并论述改进方案在企业安全生产和网络化管理中的优势。然后,针对测控系统控制要求,着重介绍了一种基于DSP嵌入式系统的以太网实现的软硬件设计,以实现嵌入式Internet。实验结果表明:改进方案能很好地缓解中心机的处理压力,提高了数据的抗干扰能力和数据共享程度,并简化了数据传输线路。

Design of Network Interface Based on DSP Embedded System

An improvement on network of a certain measure and control system is presented and the defect in the structure of the old control system is analysed. A reforming design of embedded system and distributed control system is proposed to replace the old central control system. The advantage of the improved scheme in production and management is discussed. A design of Ethernet interface based on DSP embedded system is introduced to realize embedded Internet, according to the performance index of the control system. Experiment results show that the scheme is effective and reliable.
