摘要
信息化产业时代背景下,广播事业在发展过程中,作为当下广播电台信号传输的主要设备,中波广播发射机的使用在提升信号传输稳定性的同时,也有效地降低了维护成本,但与此同时,在设备使用过程中,受极端天气的影响,发射设备的指标和参数也发生了显著变化。鉴于此,本文主要基于中波广播发射机的系统结构和技术特点,剖析了极端天气对中波发射的影响,并对干扰问题的预防对策进行了深入探讨,最终为中波广播的正常发射奠定了良好基础。
Under the background of information industry,in the development process of broadcasting industry,as the main equipment of signal transmission in current radio stations,the use of medium-wave broadcasting transmitters can not only improve the stability of signal transmission,but also effectively reduce the maintenance cost.At the same time,during the use of equipment,due to the influence of extreme weather,the indicators and parameters of transmitting equipment have also changed significantly.In view of this,based on the system structure and technical characteristics of medium wave broadcasting transmitter,this paper analyzes the influence of extreme weather on medium wave transmission,and discusses the preventive measures of interference problems in depth,which finally lays a good foundation for the normal transmission of medium wave broadcasting.
