Description

Technical Field

[0001] The present invention relates to the technical field of ship situation awareness, and in particular to a ship situation awareness system. Background Art

[0002] During the navigation and movement of ships, since ships float on the water and are large in size, they are easily affected by water currents and wind, which may cause the ships to experience bumps, swaying and lateral movement when sailing on the water. These changes in the ship's posture will affect the safety of the ship's navigation and movement.

[0003] As a gathering point and hub for water and land transportation, ports provide logistics services, information services, commercial functions and industrial functions. Ports are located along the coasts of seas, rivers, lakes and reservoirs, and are equipped with water and land transport equipment to ensure the safe entry, exit and berthing of ships. They are distribution centers for industrial and agricultural products and foreign trade import and export materials, as well as places for ships to berth, load and unload goods, board and disembark passengers, and replenish supplies. Therefore, ships need to enter ports along the way to berth, load and unload goods, and replenish supplies during their voyage.

[0004] However, port waters and approaches are generally narrow and cramped, and the channels or waters of ports are filled with various equipment and ships entering and leaving the port. Therefore, the conditions in the channels or waters are relatively complex and there are many obstacles, which causes the ship's situation to change rapidly and easily cause a collision between the ship and surrounding obstacles, seriously threatening the navigation safety of the ship. The existing ship situation detection system is unable to fully and accurately perceive the changes in the ship's situation and avoid collisions. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a ship situation awareness system, which solves the problem that the existing ship situation detection system cannot fully and accurately perceive the changes in ship situation to avoid collisions, thereby reducing the safety of ship navigation.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A ship situation awareness system, comprising a ship attitude sensor, a surrounding natural environment detection unit, a surrounding object detection module, a ship motion state measurement module and a data acquisition center;

[0008] The ship attitude sensor is used to detect attitude parameters such as the ship's tilt angle, pitch angle, roll angle and heading angle;

[0009] The surrounding natural environment detection unit is used to detect various natural environment conditions around the ship that can affect the ship's posture;

[0010] The surrounding object detection module is used to detect the distance and direction between the moving or stationary objects around the ship and the ship;

[0011] The ship motion state measurement module is used to detect the motion data of the ship;

[0012] The data acquisition center is used to obtain various detection information and parameters transmitted by the ship attitude sensor, the surrounding natural environment detection unit, the surrounding object detection module and the ship motion state measurement module. The data acquisition center is connected to the ship attitude sensor, the surrounding natural environment detection unit, the surrounding object detection module and the ship motion state measurement module.

[0013] Preferably, the ship attitude sensor comprises an inclination sensor, an acceleration sensor and a gyroscope installed on the ship.

[0014] Preferably, the surrounding natural environment detection unit includes a plurality of flow meters installed on the shore or on a bridge in the water area. The advantage of such an arrangement is that the ship can obtain the mainstream direction of the water flow in the water area near itself in time when sailing, thereby providing a reference for the ship driver to avoid the mainstream direction of the water flow from seriously affecting the ship's heading and situation, thereby improving navigation safety.

[0015] Preferably, the current meter needs to be installed mainly on piers, dock facilities, underwater buildings, obstacles, shoals and bank bumps in port waters. The advantage of such an arrangement is that it can monitor in real time the direction and velocity of water flow at locations where backflow is likely to occur, such as piers, dock facilities, underwater buildings, obstacles, shoals and bank bumps, so as to detect backflow in time and prompt ship drivers to stay away from the backflow location to ensure that the ship is not affected by the backflow and the ship's situation is seriously changed, causing navigation hazards, thereby effectively improving the safety of ships sailing in port waters and other waters with complex terrain or many obstacles.

[0016] Preferably, the surrounding natural environment detection unit also includes an anemometer installed on the ship. The advantage of such a setting is that it can accurately monitor the wind speed and direction at the location of the ship, thereby providing reference information to the ship driver to avoid serious impact of wind on the ship's situation.

[0017] Preferably, the surrounding object detection module includes multiple radars installed at various positions on the ship. The advantage of such a configuration is that it can monitor the position and distance relationship between various objects around the ship and the ship in real time, so as to promptly detect objects that are too close or approaching the ship quickly, avoid collision with surrounding objects during the ship's navigation and movement, and ensure the safety of the ship's navigation.

[0018] Preferably, the surrounding object detection module also includes a surround image system installed on the ship. The advantage of such a setting is that the ship driver can clearly see the high-definition images at various positions around the ship, so that the objects around the ship can be clearly seen, and the radar can more effectively avoid collisions with surrounding objects.

[0019] Preferably, the ship motion state measurement module includes a navigation speed sensor and a ship heading monitoring unit installed on the ship. The advantage of such a configuration is that the navigation speed sensor can monitor the ship's navigation speed to avoid safety accidents caused by speeding, while the ship heading monitoring unit can monitor the ship's navigation direction in real time to prevent the ship from deviating from the predetermined course and ensure the safety of the ship's navigation.

[0020] Preferably, it also includes an early warning prompt module, which is connected to a data acquisition center. The early warning prompt module obtains various information and parameters detected by the ship attitude sensor, the surrounding natural environment detection unit, the surrounding object detection module and the ship motion state measurement module through the data acquisition center to analyze whether to issue an early warning prompt. The advantage of such a setting is that it can timely discover possible dangerous situations from the various information and parameters obtained and promptly prompt the ship's driving personnel, avoiding the ship's driving personnel from being unable to discover dangerous situations in time due to too much information, thereby maximizing the safety of ship navigation.

[0021] Preferably, the early warning module decides whether to issue an early warning based on whether various information and parameters exceed a set threshold.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. The ship attitude sensor, surrounding natural environment detection unit, surrounding object detection module and ship motion state measurement module are used to detect and obtain information and parameters that may affect the navigation safety of the ship. Finally, these information and parameters are transmitted to the data acquisition center, so that the ship drivers can obtain these information and parameters in a timely and rapid manner, thereby providing a detailed and reliable basis for the safe driving of the ship drivers, so that the ship drivers can accurately and timely control the ship to avoid obvious changes in the ship's situation due to various external factors. In this way, the ship's situation can be reliably and fully obtained to avoid navigation accidents caused by the inability to accurately and reliably adjust the ship's situation.

[0024] 2. By setting up multiple current meters installed at the pier bank, wharf facilities, underwater buildings, obstacles, shoals and bank convexities in the port waters, the water flow direction and flow rate at the pier bank, wharf facilities, underwater buildings, obstacles, shoals and bank convexities, which are prone to backflow, can be monitored in real time, so as to detect backflow in time to remind the ship drivers to stay away from the backflow location, to ensure that the ship is affected by the backflow and the situation of the ship is seriously changed, which will cause navigation hazards, and effectively improve the safety of ships in port waters and other waters with complex terrain or many obstacles.

[0034] Furthermore, the ship attitude sensor 1 includes an inclination sensor 11 , an acceleration sensor 12 and a gyroscope 13 installed on the ship.

[0035] Furthermore, the surrounding natural environment detection unit 2 includes a plurality of current meters 21 installed on the shore or on a bridge in the water area.

[0036] Specifically, it can enable a ship to obtain the main flow direction of the water in its vicinity in a timely manner when sailing, thereby providing a reference for the ship's driving personnel to avoid the main flow direction of the water from causing serious impact on the ship's heading and situation, thereby improving navigation safety.

[0037] Furthermore, the current meter 21 needs to be installed mainly on the pier bank, wharf facilities, underwater buildings, obstacles, shoals and bank concave and convex parts in the port waters.

[0038] Specifically, it can monitor in real time the direction and velocity of water flow at locations prone to backflow, such as pier banks, dock facilities, underwater buildings, obstacles, shoals, and uneven shores, so as to detect backflow in time and remind ship drivers to stay away from the backflow location to ensure that the ship is not affected by the backflow and the ship's situation is seriously changed, which would cause navigation hazards. This effectively improves the safety of ship navigation in port waters and other waters with complex terrain or many obstacles.

[0039] Furthermore, the surrounding natural environment detection unit 2 also includes an anemometer 22 installed on the ship.

[0040] Specifically, it can accurately monitor the wind speed and direction at the location of the ship, thus providing reference information to the ship's drivers to avoid serious impact of wind on the ship's situation.

[0041] Furthermore, the surrounding object detection module 3 includes a plurality of radars 31 installed at various locations on the ship.

[0042] Specifically, it can monitor the position and distance relationship between various objects around the ship and the ship in real time, so as to promptly detect objects that are too close or approaching the ship quickly, avoid collision with surrounding objects during the ship's navigation and movement, and ensure the safety of the ship's navigation.

[0043] Furthermore, the surrounding object detection module 3 also includes a surround image system 32 installed on the ship.

[0048] Furthermore, it also includes an early warning prompt module 6, which is connected to the data acquisition center 5. The early warning prompt module 6 obtains various information and parameters detected by the ship attitude sensor 1, the surrounding natural environment detection unit 2, the surrounding object detection module 3 and the ship motion state measurement module 4 through the data acquisition center 5 to analyze whether to issue an early warning prompt.

[0049] Specifically, it can timely discover possible dangerous situations from the various information and parameters obtained and promptly alert the ship's drivers, avoiding the situation where the ship's drivers are unable to discover dangerous situations in time due to too much information, thereby maximizing the safety of ship navigation.

[0050] Furthermore, the early warning module 6 decides whether to issue an early warning based on whether the information and parameters exceed the set thresholds. Preferably, the wind force threshold is level eight, the distance threshold between the surrounding objects and the ship is fifty meters, the speed threshold of the surrounding objects approaching the ship is thirty kilometers per hour, etc. In this way, possible dangerous situations can be simply and quickly discovered based on the various ship navigation situations obtained, ensuring that the ship can avoid various risks in time to improve navigation safety.

[0051] Working principle: Please refer to Figure 1 As shown, during navigation, the inclination sensor 11, the acceleration sensor 12 and the gyroscope 13 are used to obtain the ship's attitude parameters such as the inclination angle, pitch angle, roll angle and heading angle respectively;

The current meter 21 installed at locations such as pier banks, dock facilities, underwater buildings, obstacles, shoals, and bank bumps can monitor in real time the direction and velocity of the water flow at locations such as pier banks, dock facilities, underwater buildings, obstacles, shoals, and bank bumps that are prone to backflow, thereby timely detecting backflow and prompting the ship's driving personnel to stay away from the backflow location.

[0053] At the same time, the anemometer 22 can accurately monitor the wind speed and direction at the location of the ship, thereby providing reference information to the ship's driving personnel to avoid serious impact of wind force on the ship's situation.

[0054] Among them, the radar 31 can monitor the position and distance relationship between various objects around the ship and the ship in real time, so as to promptly discover objects that are too close or approaching the ship quickly, avoid collision with surrounding objects during the navigation and movement of the ship, and ensure the safety of the ship's navigation.
