摘　　要：我国科学技术的发展十分迅速,电子通信技术也因此获得十分显著的进步,人们的生活中开始所处可见电子科技的身影。因为受到先进的科学技术的影响,广播电视技术的发展以及产业革新逐渐趋于成熟。然而,广播电视行业在现阶段还未达到较高的自动化程度,人工值守操作方式仍旧十分普遍。对于目前的经济发展情况而言,广播电视的发展方向开始趋向于小功率、多布点和单品同步覆盖发展,广播电视设施的信号源系统的备份不再局限于单一备份,开始转变为多路备份,也抛弃了单一模式,转变为多元化模式。本文的研究切入点为广播电视的信号源系统,参考实践经验,针对广电发射设施信号系统的传输和自动切换有关技术要点进行重点的分析,希望能够为广播电视行业的产业进步提供帮助。With the rapid development of science and technology in China,the electronic communication technology has made remarkable progress,and electronic technology has begun to appear in people's lives.Because of the influence of advanced science and technology,the development of radio and television technology and industrial innovation gradually become mature.However,the radio and television industry has not reached a high degree of automation at this stage,and the manual operation mode is still very common.As far as the current economic development is concerned,the development direction of radio and television tends to be low power,multi-distribution and single product synchronous coverage.The backup of signal source system of radio and television facilities is no longer limited to single backup,but begins to change to multi-channel backup,and also abandons single mode and changes to diversified mode.The starting point of this paper is the signal source system of radio and television.With reference to practical experience,this paper focuses on the analysis of the technical points related to the transmission and automatic switching of the signal system of radio and television transmission facilities,hoping to provide help for the industrial progress of the radio and television industry.
