the compression module is used for compressing the voice information through an ultra-low rate voice coding and decoding technology, so that the sending time of the compressed target voice data is less than or equal to the basic time slot;
and the voice transceiving module is used for receiving and/or sending the target voice data through the set signal channel.
10. A fire fighting communication device as defined in claim 6, wherein the setup module includes:
the acquisition submodule is used for acquiring the transmission state transmitted in each signal channel in one superslot at a specified time;
and the selection submodule is used for selecting a target signal channel with the best transmission state in each signal channel according to the transmission state to receive voice data and/or send the voice data.
