【摘要】：众所周知,现今国家的经济发展与高速公路的发展是密不可分的,高速公路现代化离不开高速公路通信系统的建设,正是优秀的通信系统带动了高速公路的蓬勃进步,高速公路通信系统支撑了高速公路的日常管理与运营,是高速信息的传输载体,为各种通信服务及会议提供传输通道,确保了通信服务的优秀程度与安全程度。一般来说,先进的高速公路通信系统可以更好地承载高速公路的各种业务,更便捷的管理高速公路的运营。本文首先介绍了国内外高速公路的发展状况与国内外高速公路通信系统的发展情况,着重对吉林省高速公路通信系统的现状进行了分析,指出高速公路通信系统在高速公路整体建设占有主要地位,说明了通信系统在高速公路建设中的重要性,提出了规划高速公路通信系统的重要意义。然后简要介绍了高速公路通信系统现有的主要传送网技术,包括同步数字系列、多业务传送平台技术以及分组交换技术,三种技术都在实际工程中广泛应用,但是同步数字系列已难以满足数据业务的传送需求,多业务传送平台在一定程度上有所改进,但改进的只是设备接口的适应性,然而从网络应用方面,分组交换网络提供了一个可以兼容各种技术,而且相对性能最好的网络。考虑到吉林省某地的实际情况,结合经济因素以及未来的发展因素,提出采用分组传送技术作为吉林省某地高速公路通信系统的方案。进而阐述了分组交换技术的发展历程,分析了此技术的主要体系即多协议标签交换;综合分析了分组传送网的主要技术,即操作管理维护系统、网络保护技术与同步技术。对分组传送网的保护技术进行了详细的阐述,分别说明了保护技术中的设备级保护、端口级保护、隧道级保护、环网级保护、伪线级保护、路由级保护,充分说明分组传送网可以稳定安全地承载高速公路所需的各种业务。最后规划设计了吉林省某地高速公路通信系统,设计了高速公路通信系统的同步、容量、保护与承载,对吉林省某地高速公路通信系统网络进行组网,详细阐述网络的组成、设备的选择、通信系统的构成。根据实际工程的实施,对于新建网络,要严格按组网安全标准验收;对于现网长支链,要加大改造力度,降低业务阻断几率;对于老旧设备,要统筹安排升级与替换等意见。本文对高速公路通信系统的设计可以替代原有通信系统,高速公路可以发挥更大的经济效益,带动吉林省某地的经济。文中经验可以辅助吉林省高速公路通信系统的升级改造,但是自身的问题还是存在的,而且通信技术的发展十分迅速,需要在提升安全、性能等方面坚持不懈地研究与优化。
[Abstract]:As we all know, the economic development of the country and the development of the highway are inseparable. The modernization of the highway can not be separated from the construction of the highway communication system. It is the excellent communication system that drives the rapid progress of the highway. Expressway communication system supports the daily management and operation of expressway and is the carrier of high-speed information transmission. It provides transmission channels for various communication services and conferences and ensures the excellent level and security of communication services. Generally speaking, the advanced highway communication system can better carry all kinds of business of highway and manage the operation of expressway more conveniently. This paper first introduces the development of expressway at home and abroad and the development of expressway communication system at home and abroad, focusing on the analysis of the current situation of highway communication system in Jilin Province. The paper points out that the communication system of expressway occupies the main position in the whole construction of expressway, explains the importance of communication system in the construction of expressway, and puts forward the important significance of planning the communication system of expressway. Then it briefly introduces the main transmission network technologies of expressway communication system, including synchronous digital series, multi-service transmission platform technology and packet switching technology, all of which are widely used in practical engineering. But the synchronous digital series has been difficult to meet the demand of data service transmission, the multi-service transmission platform has been improved to some extent, but the improvement is only the adaptability of the device interface, however, from the aspect of network application, Packet-switched networks provide a network that is compatible with a variety of technologies and has the best relative performance. Considering the actual situation of a certain place in Jilin Province, combined with economic factors and future development factors, a scheme of adopting packet transmission technology as the highway communication system of a certain place in Jilin Province is put forward. Then, the development of packet switching technology is described, the main architecture of this technology is analyzed, that is, multi-protocol label switching, and the main technologies of packet transport network, namely, operation management and maintenance system, network protection technology and synchronization technology, are comprehensively analyzed. The protection technology of packet transmission network is described in detail, including device level protection, port level protection, tunnel level protection, ring network level protection, pseudo-line level protection, routing level protection, etc. It is fully explained that packet transport network can carry all kinds of traffic needed for freeway stably and safely. Finally, the highway communication system of a certain place in Jilin province is planned and designed. The synchronization, capacity, protection and carrying capacity of highway communication system are designed. The network of highway communication system in a certain place of Jilin Province is set up, and the composition of the network is described in detail. Selection of equipment, composition of communication system. According to the implementation of the actual project, the new network should be strictly accepted according to the network safety standard; for the current network long chain, we should strengthen the transformation efforts, reduce the probability of business blocking; for old equipment, we should arrange the upgrade and replacement as a whole. In this paper, the design of highway communication system can replace the original communication system, the expressway can play a greater economic benefit and drive the economy of a certain place in Jilin Province. The experience in this paper can be used to assist the upgrading of highway communication system in Jilin Province, but there are still some problems, and the communication technology is developing very rapidly, so it is necessary to study and optimize persistently in the aspects of improving safety and performance.
