Digital emergency broadcasting host machine

Abstract

The invention discloses a digital emergency broadcasting host machine, which integrates and comprises an embedded industrial computer control center, a voice recording system, a client, a storage center, an IP data conversion module, a TS stream conversion module, an MP3 data conversion module, a database, a running memory, an encryption manager, a TTS text conversion module, a USB signal acquisition module, an audio signal acquisition module, an audio input module, a remote audio and data acquisition module, a microphone input, 4 GPRS modules, a display control system, a touch screen control and display module, a PID addressing control signal, a serial port control signal, high-low level control signals, an automatic priority level processor, a power supply, a volume detecting and adjusting module, a working state detection and display module, a satellite ground service center and a terminal data return module. An output end of the embedded industrial computer control center outputs a controlled power supply, audio and control signals of an IP network, terrestrial digital television broadcasting, RDS wired / wireless tuning, satellite and telephone / SMS / GPRS, and data to the satellite ground service center and switches to be connected with terminals.

Description

technical field [0001] The invention relates to the technical field of broadcast equipment, in particular to a digital emergency broadcast host. Background technique [0002] Emergency broadcast refers to when a major natural disaster Emergency broadcasting can provide a fast and efficient information transmission channel through various networks in case of sudden public crises such as emergencies, public health and social security, and current affairs information dissemination Or the possible harm caused by disasters can be transmitted to the public, so that the public can know what happened at the first time, how to evacuate, avoid danger, and minimize the loss of life and property; usually the government can use this machine to broadcast entertainment programs, current affairs, etc. Important news, scientific and technological knowledge, policies and regulations and other information are passed on to the people. [0003] Traditional broadcasting generally adopts a singl...

AI Technical Summary

Problems solved by technology

[0003] Traditional broadcasting generally adopts a single network transmission and control method, which cannot centrally manage the transmission of multiple network data and the control of terminals. Multiple hosts and software are required to manage different terminals during multiple network transmissions, and the operation is very cumbersome. Inconvenience, small coverage, limited transmission distance, poor security, poor scalability, single function, low reliability, inconvenient maintenance, difficult to grasp the operating status of equipment, difficult construction, low applicability, difficult to meet emergency and broadcasting needs
