Problems solved by technology
[0002] With the rapid development of maritime trade and marine fishery, the existing maritime communication technology is far from being able to meet the information transmission between the ship and the shore. Due to the limited resources of the radio stations on the ship, different ship radio stations occupy the same frequency channel and cannot realize sending and receiving. The information is sent simultaneously, and due to the distance between the ship and the shore, the optimal frequency ranges are also different, which makes the communication between the ship and the shore, and between the ships extremely difficult

A ship wireless transmission control device comprises ship terminals arranged on all ships, a transmitting / receiving platform and a shore terminal, wherein the transmitting / receiving platform and the shore terminal are located on a shore, the ship terminals are in wireless connection with the transmitting / receiving platform through a radio station, the shore terminal is in wireless connection with the transmitting / receiving platform, and the transmitting / receiving platform is used for receiving, sending and forwarding of files between the ship terminals and the shore terminal and among the ship terminals. The ship wireless transmission control device further comprises a file multi-path receiving-sending control platform, wherein the file multi-path receiving-sending control platform is connected with the transmitting / receiving platform and selectively controls different frequencies occupied by communication channels of all the ship terminals, so that files among multipoint terminals are sent and received in real time. The invention further provides a ship wireless transmission control method adopting the device. By means of the ship wireless transmission control device and method, real-time data transmission of multipoint users is achieved, and files are received and sent more timely, more flexibly and more diversely.
Description
technical field [0001] The invention relates to a ship wireless transmission control device and a control method, which are suitable for the real-time transmission of massive information between the ship and the shore, and between the ship and the ship. Background technique [0002] With the rapid development of maritime trade and marine fishery, the existing maritime communication technology is far from being able to meet the information transmission between the ship and the shore. Due to the limited resources of the radio stations on the ship, different ship radio stations occupy the same frequency channel and cannot realize sending and receiving. The information is sent simultaneously, and due to the difference in the distance between the ship and the shore, the optimal frequency range is also different, which makes the communication between the ship and the shore, and between the ships extremely difficult. Contents of the invention [0003] In view of the above pro...
