An emergency broadcasting system realizing audio broadcasting self-checking function

Abstract

The invention provides an emergency broadcast system for realizing an audio broadcast self-check function. The system comprises a platform, a transmission network, a terminal and a pass back network.The platform comprises a platform control module, a test audio file generation module, a transmission module, a platform communication module, and a first audio to text module. The terminal comprisesa terminal control module, a receiving module, an interface module, a play module, an audio acquisition module, a second audio to text module and a terminal communication module. The platform sends atest audio file to the terminal via the transmission network, and converts the test audio file into a test text file. The terminal plays the test audio file, and simultaneously collects broadcast voices in real time to generate a listening audio file, and converts the listening audio file into a listening text file. The listening text file is sent to the platform via the pass back network. The platform compares the consistency of the listening text file and the test text file. If the listening text file and the test text file are consistent, audio broadcast self-check is normal. By using the emergency broadcast system for realizing the audio broadcast self-check function, maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of emergency broadcasting, in particular to an emergency broadcasting system for realizing the self-checking function of audio broadcasting. Background technique [0002] The emergency broadcast system includes a platform and a terminal. Terminals are distributed everywhere, with many points and a wide area, especially in rural areas, where the distribution is very scattered. As the running time of the system increases, the maintenance cost will continue to rise. Audio broadcast self-check is that the emergency broadcast platform sends emergency broadcast audio to the terminal, and then automatically judges whether the terminal is playing the emergency broadcast audio, so as to self-test whether the audio broadcast is normal. The emergency broadcast system has an audio broadcast self-check function, which can simplify maintenance steps and quickly locate fault points. There is a need for an emergency broa...
