Integrated assisted positioning system for inland river navigation mark layout and application method of integrated assisted positioning system

Abstract

The invention relates to an integrated assisted positioning system for inland river navigation mark layout and an application method of the integrated assisted positioning system. The system comprisesmarking ship positioning equipment, inland river depth sounding equipment and a server. According to the application method, real-time position data of a marking ship is acquired by the marking shippositioning equipment, real-time depth data of the marking ship is acquired by the inland river depth sounding equipment, the two kinds of data are transmitted to the server in real time, and a navigation mark anchoring point position is solved in real time by inland river navigation mark layout assisted positioning software in the server; meanwhile, route guidance is performed on the marking shipaccording to the relative positional relation between the navigation mark anchoring point position obtained by solution and the real-time position data of the marking ship. Automatic acquisition andprocessing of position information and depth information of the marking ship, real-time automatic solution of the anchoring point position and route guidance of the marking ship can be completed, andautomation of inland river navigation mark layout is realized; the system is simple in structure, convenient to operate, efficient to run, high in automation level and high in practicability.

Description

technical field [0001] The invention relates to the technical field of inland waterway navigation engineering, in particular to an integrated aided positioning system for laying inland waterway navigation marks and its application method. Background technique [0002] The inland navigation aid sign (referred to as "navigation mark") is a sign indicating the boundary, direction and obstacles in the water of the inland waterway. According to different layout forms, it can be divided into shore markers fixed on the river bank and buoys floating on the river surface. Because the water level of the inland river is affected by seasonal changes and the environment, it will change dynamically. In order to reasonably mark the channel boundary and obstacles in the water, the buoy needs to dynamically adjust the floating position according to the change of the water level. [0003] With the rapid development of inland waterway shipping, the guiding role of navigation marks in ship nav...

Problems solved by technology

This method has a low degree of automation and is highly dependent on the personal experience of the operator, which further affects the positioning accuracy and operating efficiency of the navigation mark.

The inaccurate position of the navigation mark will directly affect the navigation safety of the ship

[0004] For example, Chinese patent CN204110325U discloses an auxiliary suspension buoy deployment system, which includes a main suspension, an auxiliary suspension, a buoy, and a buoy base. , Fixtures, and the slewing mechanism can drive the upper structure to rotate 360 ​​degrees. The lifting cylinder stretches to realize the cantilever lifting, the telescopic cylinder stretches to realize the cantilever stretching, and the clamping cylinder stretches to realize the clamp opening and closing; the main hoist lifts the buoy through the wire rope and hook, and the auxiliary hoist cooperates When the main crane is working, the auxiliary crane clamps the buoy through its clamps, so that the buoy can be kept vertical, thereby avoiding the shaking of the buoy and the wire rope; this invention solves the problem of the buoy shaking, thereby improving the safety and efficiency of buoy deployment, but The positioning accuracy of the layout is still limited
