摘要
探讨定义一种基于调频副载波的应急广播消息传输技术机制和协议封装格式,实现对应急广播信令和数据传输控制协议及终端设备编码规则的统一和规范化,解决各设备厂商生产的终端互不兼容导致后期维护困难等方面的问题,促进和加快各地采用调频负载波技术进行应急广播消息播发的应用系统建设和发展速度。
The definition of an emergency broadcast message transmission mechanism and protocol encapsulation format based on FM subcarrier are discussed, which realizes the unification and standardization of emergency broadcast signaling and data transmission control protocol and terminal equipment coding rules. It solves the incompatible problems of terminal equipment manufactured by different manufacturers, so as to promote and accelerate construction and development speed of EBM broadcast system that uses FM subcarrier technology.
