摘要
本文提出了一套应急广播无线覆盖适配系统的设计和实施方案。针对现有发射台设备差异性大、原无线覆盖方案简单且缺乏信号监控的问题,基于日照市的应急广播建设实践,形成了包含设备配置和信号分配的改进方案。方案针对无线调频和中波广播,通过技术改造和适配器、切换器等设备的优化配置,实现了信号的安全、可控播出,并考虑了应急情况下的快速处置能力。此外,文中还探讨了无线调频RDS信号处理,确保了广播的规范性和安全性。
This article proposes a design and implementation plan for an emergency broadcast wireless coverage adaptation system.Based on the emergency broadcasting construction practice in Rizhao City,an improved plan including equipment configuration and signal allocation has been developed to address the problems of significant differences in existing transmitter equipment,simple original wireless coverage schemes,and lack of signal monitoring.The plan is aimed at wireless frequency modulation and medium wave broadcasting.Through technological transformation and optimized configuration of adapters,switches,and other equipment,it achieves safe and controllable signal broadcasting and considers the ability to quickly respond to emergencies.In addition,the article also discusses the processing of wireless FM RDS signals,ensuring the standardization and security of broadcasting.
