摘　　要：本文首先结合中央广播电视节目无线数字化覆盖工程的建设实施情况,简要介绍我国国标地面数字电视单频网当前现状及发展趋势。其次通过对国标地面数字电视单频网组网技术、常见问题、网络优化设计方法的分析介绍,阐述开展地面数字单频网监测工作的重要作用。最后从监测点选取、监测内容、监测方法等角度提出地面数字电视单频网监测管理方面的技术思路以及对智能化地面数字电视单频网监测系统架构的设想。This paper firstly introduces the current situation and development trend of the DTMB single frequency network, according to the recent digital radio and television construction project. Secondly, the important role of the DTMB single frequency network monitoring is expounded in aspects of the standard networking technology, common problems and optimization design methods. Finally, some technical ideas from the perspectives of monitoring location selection, monitoring content and monitoring methods are addressed for DTMB single frequency network management. Furthermore, an assumption of SFN intelligent monitoring system architecture is given for discussion.
