Multi-backup uninterrupted network broadcast cloud audio transmission system

Abstract

The invention provides a multi-backup uninterrupted network broadcast cloud audio transmission system, which is used for solving the problem that a wired network broadcast audio transmission network can interrupt transmission under the conditions of network disconnection and power failure. The system comprises a wired network broadcast audio mainboard for providing an audio signal; a wireless cellular communication cloud streaming media mainboard which is connected with the cloud audio streaming media server and receives a cloud network audio signal; a backup automatic switching module, wherein a constant-voltage audio signal is backed up in the backup automatic switching module, and the backup automatic switching module is connected with the wired network broadcast audio mainboard and thewireless cellular communication cloud streaming media mainboard, and selects and outputs one of an audio signal sent by the wired network broadcast audio mainboard, an audio signal sent by the wireless cellular communication cloud streaming media mainboard and a backup constant-voltage audio signal in the backup automatic switching module; a audio signal output interface which is connected with the backup automatic switching module and outputs an audio signal to the loudspeaker; and a power supply module which supplies power to the system.

Description

technical field [0001] The invention relates to the technical field of network broadcast cloud audio transmission system, in particular to a multiple backup uninterrupted network broadcast cloud audio transmission system. Background technique [0002] Most of the current network broadcast audio transmission systems completely rely on wired audio transmission networks. However, in an emergency, the industry still has not given a good solution for how to realize the uninterrupted output and backup transmission of network audio in case of possible network and power outages. Therefore, the stability of the network broadcasting audio transmission system has been challenged. How to realize the stable transmission of the network audio system in important application scenarios has become a very challenging topic even when the cable network is disconnected and the mains power is cut off. Contents of the invention [0003] The purpose of the present invention is to overcome the def...
