Research On Expressway Intelligent Communication System Based On ASON Technology

Highway intelligent communications system is not only able to provide means ofcommunication to highway management and driving, but also to provide specialized transportplatform to support the monitoring system, charging system and the management andmaintenance system. In order to meet present and future business requirements of highway, itis need to highway communication system of reasonable planning and design, making it ahighly efficient, safe, fast, and t meet the needs of the development of highwaycommunication in the future.With the implementation of the provincial highway interconnection charges, centralizedmonitoring, accompanied by a sudden image business communication carrier systems with ahigher demand for high survivability of communications networks, scalability, manageability,etc. The needs have become increasingly prominent. SDH and later MSTP technology tobuild communication networks have become increasingly "powerless". Therefore, theconstruction of an efficient to meet the present transmission platform for the future become animportant consideration for highway operations The paper introduced ASON technology inShaanxi highway communication system design, starting from a relatively simple area of theline conditions, the introduction of ASON steps from point to plane, then these local ASONnetwork are interconnected, thus realization of the intelligent exchange of all-optical network.The design also uses MESH networking, and communications network has better scalabilityand flexibility to adapt to the evolving needs of the business.The paper first points of the highway communication services and communicationtechnologies, the choice of highway communication technologies were discussed Xi’an toTongchuan highway communication system design, research, communications systemarchitecture, the trunk optical fiber digital transmission systems, integrated service accessnetwork systems, telephone switching systems, and support the network design. The thesisthen ASON equipment with SDH equipment joint networking and Xi’an to Tongchuan highway communication system ASON network design. Finally, highway communicationsystem based on ASON technology, respectively, described the implementation of thebackbone transmission systems, digital telephone switching systems, data and imagetransmission system, and video conferencing systems, the basic realization of intelligentcommunication system for a highway of all business functions, and give full play to theadvantage of ASON technology.
