摘　　要：广播电视是传播信息的主要载体工具,在新媒体时代,广播电视同样扮演着举足轻重的角色,通过对广播节目播出时间与内容的可靠控制,可进一步发挥传统媒介的应用价值。作为广播电视信号传输的基础,中波发射机的设置、监测与维护工作越来越受到行业人员的关注,文章便以此为背景,围绕智能动态监测发射机的方法展开了讨论,提出先对监测环境做抗干扰处理,再通过多串口卡对数据进行采集,最后校准入射(反射)功率的方案,并通过实验证实了所提出方法的可行性、可靠性,以供有关人员参考。Radio and television are the main carrier and tool for disseminating information.In the era of new media,radio and television also play a crucial role.By reliably controlling the broad-cast time and content of radio programs,the application value of traditional media can be further realized.As the foundation of broadcasting and television signal transmission,the setting,moni-toring,and maintenance of medium wave transmitters are receiving increasing attention from in-dustry personncl.Against this background,this article discusses the methods of intelligent dy-namic monitoring transmitters,proposes a scheme of first anti-interference treatment of the mo-nitoring environment,then collcting data through multiple serial cards,and finally calibrating the incident(reflected)power,And the feasibility and reliability of the proposed method have been confirmed through cxperiments,for reference by relevant personncl.
