Description

technical field [0001] The invention belongs to the technical field of short-wave radio data communication, and in particular relates to a conversion device and method for a short-wave radio data communication interface. Background technique [0002] Short-wave communication uses a frequency range of 2 to 30Mhz, using ground waves to achieve short-distance communication, or using sky waves to achieve long-distance communication through ionospheric reflection. Due to the indestructible nature of the ionosphere, short-wave communication has always been an important means of military command, emergency rescue and disaster relief. [0003] Shortwave data communication currently mainly uses 3kHz bandwidth to transmit data in China, and the highest wireless transmission rate is 2400bps. Due to the limitation of the wireless communication rate, the data communication interface provided by the shortwave radio station generally adopts the RS232 interface, and the interface rate is u...
