The invention provides an emergency broadcast system with 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 an audio to text module. The terminal comprises a terminal control module, a receiving module, an interface module, a play module, an audio acquisition module, and a terminal communication module. The platform sends a test 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 to generate a listening audio file in real time, and sends to the platform via the pass back network. The platform converts the listening audio file into a listening text file, and compares the consistency of the test text file and the listening text file. By using the emergency broadcast system with 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 with an audio broadcasting self-inspection function. 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 broadcast syste...
