The invention relates to the technical field of short-wave fax communication, and discloses a ship
communication device for short-wave fax communication and a short-wave fax transmission method in order to solve the problem of low
signal transmission reliability in a scene in which current ship communication devices depend on short-wave communication to carry out fax transmission. The equipment comprises a wired fax module, a main control module and at least one
wireless transmission module, the wired fax module is connected with an external fax
machine through a cable, the main control module is connected with the wired fax module through the
Ethernet, and the main control module is further connected with at least one
wireless transmission module in parallel through the
Ethernet; each
wireless transmission module is connected with the short-wave
radio frequency equipment through an
optical fiber; in the short-wave fax sending process, the main control module is used for selecting a target
wireless transmission waveform according to an intercommunication object short-wave channel and selecting a target
wireless transmission module matched with the target
wireless transmission waveform from the at least one wireless transmission module. By adopting the equipment, the fax transmission requirements of high reliability and high adaptability of a short-wave channel can be met.
