SNMP在运维系统公交车载终端上的设计和实现研究

针对目前公交车载嵌入式终端存在没有统一网络管理机制的问题,设计了基于公交车载终端的SNMP网络管理代理系统。着重研究和设计了SNMP网管代理系统的软件部分,完成了SNMP网管系统的代码编写和在车载终端上的移植。系统通过分析终端特性和管理参数,采用SNMP消息机制,完成对设备的管理和与管理站的通信,方便对公交车载终端的统一管理,也增强了公交系统的安全性。通过在ZTM2001上部署和测试,验证了设计的可靠性、稳定性和故障检测能力。

Design and Implementation for SNMP's Using in Operation and Maintenance System on the Bus Terminal

For there is no unified network management mechanism on bus terminal,the article designs the SNMP network management agent system.The article focuses on research and design of the SNMP network management agent system software,and completes the coding and transplant on board unit.The System completes equipment management and communication with the management station,by analyzing the terminal characteristics and management parameters,and uses SNMP-message mechanism to facilitate the unification of the transit bus terminal management,and also enhances the safety of the bus system.The design＇s reliability,stability and fault detection capabilities are verified,by disposing and testing on ZTM2001.
