Abstract

The invention relates to a multimode emergency broadcast terminal with FM-CDR receiving. Comprising an FM-CDR receiving module, an FM-RDS receiving module, a DVB-C receiving module, a DTMB receiving module, a DVB-S receiving module, a digital medium wave receiving module, an IP network module, a main control module, a safety module, a storage module, a digital-to-analog conversion module, an audio switching module, an analog audio output module, an audio acquisition module and an output module. According to the method and the device, the emergency broadcast messages are simultaneously received and processed by multiple signal channels of digital frequency modulation FM-CDR, FM-RDS, DVB-C, DTMB, DVB-S, digital medium wave and IP networks, the emergency broadcast messages can still be received through other channels for emergency broadcast playing under the condition that partial channel signals are interrupted, and the channel anti-disaster performance of the emergency broadcast terminal is improved.

Description

technical field [0001] The invention belongs to the technical field of emergency broadcasting, and in particular relates to a multi-mode emergency broadcasting terminal including FM-CDR reception. Background technique [0002] The emergency broadcast system consists of an emergency broadcast platform, an adapter, a transmission coverage system, and an emergency broadcast terminal. The emergency broadcast platform transmits emergency broadcast messages to the emergency broadcast terminal through the adapter and the transmission coverage system for playback. The emergency broadcast message includes emergency broadcast instructions and emergency broadcast content. The emergency broadcast content is the supplementary content of the message (text, audio, audio and video) or the parameters of the specified broadcast and TV programs. [0003] The emergency broadcast terminal is an integral part of the emergency broadcast system and the key to solving the "last mile" of emergency b...
