Design and Application of Municipal Emergency Broadcasting Adaptation System in Heterogeneous Transmission Network
Municipal emergency broadcasting platform is a key link in the emergency broadcasting system.Based on a series of emergency broadcasting technical standards,this paper adapts and designs the adaptive system architecture of each transmission link according to local conditions,so that the municipal emergency broadcasting platform can invoke various transmission coverage resources and achieve accurate broadcasting and comprehensive coverage of emergency broadcasting signals through various transmission channels.Through the real-time monitoring of the status data of the backpass terminal,the omnidirectional connection,multi-level linkage and controllable management of the emergency broadcasting platform,system and terminal in the heterogeneous transmission network are realized.
