摘要
SCM作为一种广泛的嵌入式系统,被常用在不同的传感器,机器人,汽车,端口通信,回路控制上等。单片机系统通常会由于电压输入的触发,影响其内部的程序逻辑,致使其输出状态改变。SNMP是IP网络管理设备中的一种标准协议,它提供了出色的功能,比如扩展能力,信息管理,鉴权,加密以及接入控制。为了能提供可扩展的控制模式,本文旨在设计一种在单片机系统上的SNMP代理。用户可通过SNMP命令有效控制单片机控制器设备。本文中的SNMP代理虽然集成了SNMP和MCU的数据库功能,未集成信息管理数据库,但是是一种小的关于单片机的设计。这个技术会帮助开发者基于单片机网络应用建立一个小的SNMP代理。对比现代网络设备,此技术扩展了其应用能力以及配套了更多的模块管理,使更多的网络模块设备管理更加便捷化。
SCM(Single Chip Micro controller)is widely used in all kinds of embedded system,it often combined with different types of sensors,robot,hybrid cars,communication interface,control circuit,etc.Usually single chip microcomputer system triggered by the input voltage,it will affect the internal program logic,then make the output state change.Simple network management protocol(SNMP)is a standard protocol in IP network management equipment.It provides outstanding features such as extendibility,information management,authentication,encryption,and access control.In order to be able to provide a scalable control mode,this paper proposes a design for single chip microcomputer system of SNMP agent.Users can control microcontroller devices through the agency of SNMP command to effectively.We integrate the function of library of SNMP and MCU,there are no management information database,but there is a design of a small network embedded devices.This technology will help developers build a small SNMP agent based on single chip microcomputer network application.Compared with the modern networked embedded devices,the technology extends its applicability,and make with the module number of management become more then.and make it convenient to management the networked devices as the number of modules increase.
