摘　　要：为了提高广播信号的强度,提升广播系统发射信号的覆盖范围,开展基于广播数据系统(Radio Data System,RDS)技术的数字调频同步广播系统设计研究。硬件设计方面,选择PowerEdge-R440机架式服务器作为广播系统的信息发布服务器,选择IMH89000-M10型号的RDS编码器。软件设计方面,设置广播系统RDS信号传输物理通道,引进RDS技术,将信号在局域宽带网络之间进行动态交换,实现数字调频同步广播播控优化设计。通过对比实验证明,设计的广播系统可以在保证终端对广播信号接收效果的基础上,扩大广播信号覆盖范围。In order to improve the strength of broadcast signal and the coverage of transmitted signal of broadcast system, the design and research of digital FM synchronous broadcast system based on Radio Data System(RDS) technology is carried out. In terms of hardware design, PowerEdge-R440 rack server is selected as the information publishing server of the broadcasting system, and IMH89000-M10 RDS encoder is selected. In terms of software design, the physical channel for RDS signal transmission of the broadcasting system is set, RDS technology is introduced, and the signals are dynamically exchanged between local broadband networks to realize the optimal design of digital FM synchronous broadcasting control. Through comparative experiments, it is proved that the designed broadcasting system can expand the coverage of broadcasting signals on the basis of ensuring the receiving effect of broadcasting signals by terminals.
