Research on the Key Technology of Ship VHFDSC Wireless Communication Network

摘要

Sea transport occupies a very important position in human life. In recent years, due to the increase of traffic volume of vessels, the increase of transportation tonnage and the increase of ship speed have made the water transport environment more crowded and dangerous. Ship traffic safety is the first problem. The shadow of the sea condition and the topography must exist in many blind areas. It cannot be fully covered, and it is difficult to contact the ship with distress and handle the alarm of the ship. The ship's safety information cannot be reported to the shore in a timely and reliable manner, and the so-called coordinated search and rescue cannot be realized effectively. Therefore, this paper proposes a design scheme for the establishment of VHFDSC regional network, which can realize the complete seamless coverage of offshore busy waterway and port area ship safety information, so as to ensure the safety of navigation.
