Abstract

The invention discloses a navigation planning and correction system of a tugboat. The navigation planning and correction system is provided with an integrated antenna, a GPS (Global Positioning System), a fixed floating beacon, an airborne radar for sea search and a central processing unit, wherein the integrated antenna has a satellite signal receiving function; the GPS is used for acquiring the current tugboat position; the fixed floating beacon is arranged at a working sea area of the tugboat and is provided with a radar responder; the airborne radar for sea search is arranged on the tugboat and is used for transmitting radar waves, receiving back waves of the radar responder and acquiring a self position; the central processing unit is used for receiving current tugboat position information acquired by the GPS and a return position signal of the airborne radar for sea search, and calculating the current tugboat position. According to the navigation planning and correction system, a GPS positioning technology is utilized as a main positioning means, and the positioning floating beacon with a radar back wave reflection function is utilized as an auxiliary positioning means, so that the current tugboat position is effectively mastered in real time; furthermore, the navigation route of the tugboat is monitored in real time, and when the tugboat yaws, yawing prewarning and a corresponding operation suggestion are given out.

Description

technical field [0001] The invention relates to a navigation planning and correction system of a tugboat. It involves patent classification number G08 signal device G08G traffic control system G08G3 / 00 traffic control system for marine vehicles. Background technique [0002] With the rapid development of my country's shipping industry, international shipping trade has become more and more busy, and the use of tugboats has become more and more frequent. Faced with such a large number of tugboats, it is already difficult to rely on traditional manual loose management methods Accurate scheduling and evaluation. [0003] Now the development of GPS technology has become increasingly mature, and the positioning accuracy has also ranged from tens of meters to several meters. And with the popularization of technology, the use of GPS has become more and more widespread. Interaction with other devices is also getting easier and cheaper. Contents of the invention [0004] Aiming a...
