我国航天系统中采用简单网络管理协议(Simple Network Management Protocol,SNMP)构建测控设备统一化监控管理平台。针对采用ASN.1(Abstract Syntax Notation 1)语法管理信息库(Management Information Base,MIB)方法,编写地面测控设备MIB信息时容易出现出错、易读性差的问题,提出采用XML(Extensible Markup Language)语言来描述MIB信息的树状结构,并举例说明地面站设备MIB库转换为XML描述的方法。介绍了运管代理软件处理的消息类型,并详细介绍地面设备运管代理软件的设计方案和软件实现关键技术。仿真结果表明,提出的方法实现了网管代理的基本功能,提高了程序维护效率。
China’s aerospace system using Simple Network Management Protocol (Simple Network Management Protocol, SNMP) build monitoring and control equipment unified monitoring and management platform. Aiming at the problem of error and poor readability in the preparation of MIB information of surface measurement and control equipment by using ASN.1 (Abstract Syntax Notation 1) Management Information Base (MIB) method, an XML (Extensible Markup Language) language To describe the tree structure of the MIB information and illustrate the method of converting the ground station device MIB library into an XML description. The types of messages handled by the transport agent software are introduced, and the design scheme of the software of the transport agent of the ground equipment and the key technologies of the software are introduced in detail. The simulation results show that the proposed method realizes the basic functions of network management agent and improves the efficiency of program maintenance.
