The unmanned ship comprehensive data transmission system used for receiving the data transmitted by the unmanned ship or the ground control center based onthe unmanned ship comprehensive data transmission method comprises a broadband radio station RF receiving antenna, a narrow-band radio station RF receiving antenna, a broadband radio station receiving unit, a narrow-band radio station receiving unit and a multi-channel data demultiplexing module. Through adoption of the unmanned ship comprehensive data transmission method and the unmanned ship comprehensive data transmission system of the invention, remote, multi-channel, full-duplex, efficient and comprehensive data transmission of the unmanned ship can be achieved, distance and efficiency of data transmission can be increased, an anti-interference capability can be raised, and the whole secure and stable performance of the unmanned ship system also can be improved.
Description
technical field [0001] The invention belongs to the field of unmanned ships, and more specifically relates to a comprehensive data transmission method and system for unmanned ships. Background technique [0002] The unmanned ship system can be efficiently used in water surveying and mapping, environmental monitoring, military reconnaissance and other fields. The conventional communication method is to use narrowband radio as the transmission channel for unmanned ship control commands. In a complex electromagnetic environment and when performing long-distance patrol missions, narrowband radio stations may lose control commands due to limited transmission power and frequency band interference. As a result, unmanned ships cannot accurately execute the control commands issued by the ground control center in real time Complex task requirements for unmanned ships. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a meth...
