Embodiment 1

[0070] Such as figure 1 As shown, Embodiment 1 of the present invention provides a ship inland river navigation early warning and auxiliary collision avoidance method, comprising the following steps:

[0071] S1. Obtain the data of the boundary of the waterway and the data of the obstructions, divide the waterway into a plurality of flight segments, associate the data of the boundary of the flight segments and the data of the obstructions corresponding to each flight segment with the corresponding flight segments, and establish a basic database;

[0072] S2. Obtain the position data and heading data of the ship;

[0073] S3. According to the real-time position data of the ship and the segment boundary data of each segment, obtain the segment where the ship is located as the current segment;

[0074] S4. Comparing the heading data of the ship with the direction data of the current voyage, it is judged whether the ship is traveling along the course. Data acquisition of collisi...

Embodiment 2

[0167] Embodiment 2 of the present invention provides a ship early warning and auxiliary collision avoidance device for inland river navigation, including a processor and a memory, and a computer program is stored on the memory, and when the computer program is executed by the processor, the implementation of Embodiment 1 is realized. Early warning and auxiliary collision avoidance methods for inland river navigation of ships.

[0168] The ship inland river navigation early warning and auxiliary collision avoidance device provided by the embodiment of the present invention is used to realize the ship inland river navigation early warning and auxiliary collision avoidance method. It is also provided with the auxiliary collision avoidance device, and will not be repeated here.

Embodiment 3

[0170] Embodiment 3 of the present invention provides a ship inland river navigation early warning and auxiliary collision avoidance system, including the ship inland river navigation early warning and auxiliary collision avoidance device provided in embodiment 2, and also includes a collection device and a display device;

[0171] The collection device is used to collect the position data and heading data of the own ship, and the display device is used to display the yaw warning information and auxiliary collision avoidance decision information.

[0172] Specifically, the acquisition device in this embodiment is composed of a marine radar and a set of AIS equipment; the early warning and auxiliary collision avoidance device for inland river navigation of ships uses a computer, and the early warning and auxiliary collision avoidance methods for inland river navigation of ships are used on the computer to realize data processing calculations, etc. The display device includes an ...

Abstract

The invention relates to a ship inland river navigation early warning and auxiliary collision avoidance method, which comprises the following steps of obtaining navigation channel boundary data and navigation obstacle data, dividing a navigation channel into a plurality of navigation segments, and associating the navigation segment boundary data and the navigation obstacle data corresponding to each navigation segment with the corresponding navigation segment; acquiring position data and heading data of the ship; according to the position data of the ship and the route segment boundary data ofeach route segment, obtaining the route segment where the ship is located as a current route segment; judging whether the ship runs along the navigation channel or not, and if so, acquiring yaw dataaccording to the navigation segment boundary data of the current navigation segment, acquiring collision avoidance data according to the navigation obstruction data of the current navigation segment,and acquiring auxiliary decision data corresponding to the collision avoidance data based on an inland river collision avoidance rule; and outputting yaw early warning information based on the yaw data, and outputting auxiliary collision avoidance decision information based on the auxiliary decision data. According to the invention, effective early danger early warning and navigation assistance functions can be realized.

Description

technical field [0001] The invention relates to the technical field of navigation collision avoidance, in particular to a ship inland river navigation early warning and auxiliary collision avoidance method, device, system and computer storage medium. Background technique [0002] In recent years, the country has accelerated the construction of the inland waterway shipping center. Due to the narrow and curved inland channel, the large number of inland ships and the high density of navigation, even if the inland navigation environment is improved, the number of inland ships is gradually decreasing, and ship collision accidents still occur frequently. According to statistics, among the ship traffic accidents in 2019, inland waters accounted for 49.3%, and inland ships accounted for 59.9%. In the process of water transportation, there are potential accident hazards whether it is people, machines or the environment. Once a water transportation accident occurs, it will often caus...
