基于W5300的嵌入式网络管理控制系统设计

简单网络管理协议以其易于使用、扩展性强、功能强大等优点在网络管理系统中有广泛应用。针对测控设备的网络管理需求,以单片机为核心,设计了一种基于以太网控制器W5300的嵌入式网络管理控制系统。详细讨论了W5300作为网络接口的软硬件实现方法,以及单片机对简单网络管理协议报文进行处理的软件设计方法。该系统可以实现网络管理站、代理站及测控设备分机的网络通信,数据传输可靠有效。本系统结构简单、实时性强、可靠性高,有效保证了网络管理控制系统的网络管控能力。

Design of Embedded Network Management ControlSystem Based on Ethernet Controller W5300

Simple network management protocol (SNMP) is widely used in the network management control system because of simpleness, strong expansibility and powerful. According to the network management requirements of the equipment, a kind of embedded network management control system based on the ethernet controller W5300 is designed. The design content mainly includes two aspects, one is the hardware and software design method of W5300 as network interface, the other one is the software design method of the single chip microcomputer to deal with simple network management protocol (SNMP) message. The system can achieve network communication among management station, agent station and equipment. The network data transmission is reliable and effective. The system has the advantages of simple structure, strong real-time performance and high reliability. It can effectively to ensure that the network control ability.
