Example Embodiment

[0069]Example 1

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

[0071]S1. Obtain the channel boundary data and obstruction data, divide the channel into multiple flight segments, associate the segment boundary data and obstruction data corresponding to each segment with the corresponding flight segment, and establish a basic database;

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

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

[0074]S4. Compare the course data of the ship and the direction data of the current flight segment to determine whether the ship is traveling along the course. If so, obtain the yaw data based on the segment boundary data of the current flight segment, and based on the obstacles of the cu...

Example Embodiment

[0166]Example 2

[0167]Embodiment 2 of the present invention provides an early warning and auxiliary collision avoidance device for ship inland water navigation, including a processor and a memory, and a computer program is stored on the memory. When the computer program is executed by the processor, the device provided in embodiment 1 is implemented Early warning and auxiliary collision avoidance methods for ships’ inland navigation.

[0168]The ship inland navigation early warning and auxiliary collision avoidance device provided by the embodiment of the present invention is used to realize the ship inland navigation early warning and auxiliary collision avoidance method. Therefore, the technical effect of the ship inland navigation early warning and auxiliary collision avoidance method is that the ship inland navigation early warning It is the same as the auxiliary collision avoidance device, so I will not repeat it here.

Example Embodiment

[0169]Example 3

[0170]Embodiment 3 of the present invention provides a ship inland navigation early warning and auxiliary collision avoidance system, including the ship inland 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 position data and heading data of the ship, and the display device is used to display the yaw early 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 ship's inland navigation early warning and auxiliary collision avoidance device adopts a computer, and the computer uses the ship's inland navigation early warning and auxiliary collision avoidance method to realize data processing calculations, etc. The display device includes an information transmission device and a displ...

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...
