【摘要】：对于我国智慧城市建设的逐步推进,有线电视网络的现代化建设也是智慧城市发展的重要组成部分。为了解决当前有线电视网络的分布混乱、管理困难、以及由于有线电视设备的型号繁杂引起的无法进行统一管理等问题,本文设计了面向智慧城市的有线电视网络管理系统,对于推动有线电视网络的发展以及三网融合有着重要的意义。本文通过对WebGIS技术以及网络理管技术进行详细了解并深入研究,同时结合有线电视网络的通信特点,设计并实现了包含呈现层、服务层以及代理层三层结构的有线电视网络管理系统。首先,针对于现今有线电视设备分布混乱、管理困难的问题,本系统在呈现层使用WebGIS技术,对有线电视设备进行定位设置与显示,展示各有线电视设备的性能参数,实现有线电视机房地理信息的统一管理,并且直观地显示各处有线电视设备的故障信息,进行故障定位;其次本文在服务层对系统的资源管理、性能管理、配置管理以及故障管理进行设计,并且获取与解析网络中的SNMP报文进行存储分析,为上层的数据显示提供支持;同时,对于众多有线电视设备无法统一进行网络管理的问题,本系统在代理层对多种有线电视管理设备通信方式进行分析与研究,应用动态链接库技术,将不同通信协议设备的协议转换程序编译为相应的动态链接库,然后通过查询配置文件中对应端口有线电视设备的通信协议代号,动态导入库文件而不必影响系统正常运行,实现了多种有线电视设备的通用管理,节约网络资源;最终基于面向智慧城市的设计理念,设计系统框架,并完成系统的功能实现。最后,应用测试软件对本系统的稳定性进行测试。测试结果表明,本系统能够及时地响应用户所发送的设置、查询请求,能够持续稳定地对有线电视设备性能参数进行获取,能够支持多用户并发操作,因此本系统对于推动有线电视网络的发展具有实用意义。
[Abstract]:The modernization of CATV network is also an important part of the development of intelligent city.In order to solve the problems of disordered distribution and difficult management of CATV network, and the difficulty of unified management caused by the complexity of CATV equipment, a CATV network management system for intelligent city is designed in this paper.It is of great significance to promote the development of CATV network and the integration of three networks.In this paper, the WebGIS technology and network management technology are understood and studied in detail. At the same time, combining with the communication characteristics of CATV network, a presentation layer is designed and implemented.CATV network management system with service layer and agent layer.First of all, aiming at the problem of disordered distribution and difficult management of CATV equipment, this system uses WebGIS technology in the presentation layer to locate and display the CATV equipment and display the performance parameters of each CATV equipment.Realize the unified management of the geographical information of the CATV computer room, and display the fault information of the cable TV equipment directly, carry on the fault location. Secondly, this paper manages the system resource, the performance management in the service layer,Configuration management and fault management are designed, and the SNMP packets in the network are obtained and analyzed for storage and analysis, which provide support for the data display in the upper layer, and at the same time, for many cable television equipment can not be unified in network management.This system analyzes and studies the communication methods of many CATV management equipments in the agent layer, and compiles the protocol conversion program of different communication protocol devices into the corresponding dynamic link library by using the dynamic link library technology.Then, by querying the corresponding communication protocol code of the port cable TV equipment in the configuration file, dynamically importing the library file without affecting the normal operation of the system, the general management of various cable TV equipments is realized, and the network resources are saved.Finally, based on the intelligent city oriented design concept, the system framework is designed, and the function of the system is realized.Finally, the stability of the system is tested by testing software.The test results show that the system can respond to the settings sent by the users in time, query requests, continuously and stably obtain the performance parameters of CATV equipment, and can support multi-user concurrent operation.Therefore, this system has practical significance for promoting the development of CATV network.
