摘要
依据国家广播电视节目无线覆盖工程建设的相关要求,全国各省广播电视台结合数字化建设实际,积极运用新建的微波传输线路,高效完成对省内各微波传输节点的备份信源覆盖任务。基于此,阐述数字微波传输网的组织架构与工作原理,在此基础上,提出一套省级无线覆盖工程备份信源数字微波传输网建设方案,并重点分析设计思路、关键配置以及核心技术,最后通过工程实践给出方案实施中重难点问题的解决措施。
According to the relevant requirements of the national radio and television program wireless coverage project construction,the radio and television stations in all provinces in the country actively use the newly built microwave transmission lines in combination with the actual digital construction to efficiently complete the backup information source coverage task for each microwave transmission node in the province.Based on this,this paper describes the organization structure and working principle of digital microwave transmission network,and on this basis,puts forward a set of provincial wireless coverage project backup information source digital microwave transmission network construction scheme,and focuses on the analysis of design ideas,key configuration and core technology,and finally gives the solution of the key and difficult problems in the implementation of the scheme through engineering practice.
