Description

Technical Field

[0001] The present disclosure relates to the technical field of ship safety design, and in particular to a water-fall positioning device, a ship control system and a ship. Background Art

[0002] The number of passengers on a cruise ship can range from a few hundred to thousands. While ensuring the passengers' travel experience, safety is of paramount importance. With the gradual improvement of relevant international conventions, the probability of accidents on cruise ships has gradually decreased, and the safety after accidents has also been continuously improved.

[0003] Among the many safety issues of cruise ships, the current regulations only put forward design requirements for the maneuverability of ships in response to the phenomenon of passengers falling into the water. Williamson turn and Schiano turn are usually used for search and rescue. Among them, Williamson turn can ensure that the ship turns to the position where the passengers fall into the water within a certain period of time, but it is only suitable for rapid rescue after witnessing the passengers fall into the water. It is time-sensitive and it is difficult to take into account the situation of non-immediate missing persons; Schiano turn can ensure that the ship searches in reverse along the track, but it is difficult to play a role in poor weather conditions at sea or low visibility at night.

[0004] For this reason, some cruise operating companies require passengers to wear safety bracelets after boarding the ship. The safety bracelets can provide real-time feedback of the passengers' location signals. When a passenger falls into the water, the positioning signal and the change in the relative position of the ship can serve as a warning, allowing search and rescue to be carried out more quickly and accurately.

[0005] However, although the safety bracelet can provide rapid warning and accurate positioning of passengers falling into the water, this method still has certain limitations and cannot guarantee that all passengers on the ship will wear the bracelet as required. When the bracelet is lost, forgotten to be worn, or deliberately taken off, it is difficult to provide rapid warning and rescue for passengers who fall into the water. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defect in the prior art that a person who falls into the water cannot be accurately located, resulting in difficulty in rapid warning and rescue, and to provide a person-falling-into-water positioning device, a ship control system and a ship.

In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0040] In the embodiments of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0041] Example 1

[0042] In a specific embodiment of the present disclosure, a water-falling positioning device is provided, which is arranged at a preset position of a ship, such as Figure 1 As shown, the water-falling positioning device includes a control module 100, M information collection devices 200 and N ejection devices 300 which are communicatively connected to the control module 100, wherein M and N are both positive integers; the M information collection devices and the N ejection devices 300 are arranged at different positions of the ship, and the ejection area of ​​each ejection device 300 corresponds to the information collection area of ​​at least one information collection device;

[0043] The information collection device 200 is used to collect content information within an information collection area within a preset range from the ship and send it to the control module 100;

[0044] The control module 100 is used to respond to the content information characterizing that the target object is in a falling-in-water state, determine a matching target projectile device based on the target information collection area, and generate a control instruction to send to the target projectile device, drive the target projectile device to project a locating object along a preset projectile direction within the projectile area, so as to track the falling-in-water range of the target object based on the locating object.

[0045] Specifically, the information collection device 200 can be an image collection device, a sound collection device, an infrared detection device, or other device that can obtain real-time dynamic information of the area surrounding the ship, and an entity for positioning is placed in the ejection device 300. By setting N ejection devices 300 and M information collection devices 200 at multiple different positions on the ship, when the control module 100 identifies that a person has fallen into the water from the real-time dynamic information collected by the information collection device 200, the real-time dynamic information is traced, and then the target ejection device located closest to the falling-into-water position is determined according to the ship's orientation corresponding to the real-time dynamic information, and the target ejection device is controlled to eject the positioning object along the preset ejection direction, so as to use the positioning object to simulate the position change of the person who fell into the water after falling into the water, so that the search and rescue personnel can accurately determine the search and rescue range according to the positioning object, thereby improving the success rate of the search and rescue.

[0046] Among them, considering that people will be close to the hull when falling into the water, the throwing situation of the positioning object is tested before setting the throwing device 300, and the throwing device 300 is installed at a fixed and relatively reasonable angle. At the same time, the target throwing devices corresponding to the real-time dynamic information in different directions are pre-set. When it is recognized that a person has fallen into the water, the target throwing device is directly controlled to throw the positioning object according to the direction of falling into the water to ensure the accuracy of positioning.

[0047] In a specific achievable method, a launching device 300 may be provided on the port and starboard sides of the ship, respectively. When the real-time dynamic information collected by any one of the information collection devices 200 located on the left side of the ship indicates that a person has fallen into the water, the launching device 300 on the port side is controlled to launch the locating object. Conversely, when the real-time dynamic information collected by any one of the information collection devices 200 located on the right side of the ship indicates that a person has fallen into the water, the launching device 300 on the starboard side is controlled to launch the locating object.

[0048] This specific implementation method utilizes information collection equipment to perform real-time monitoring of the area surrounding the ship. When a person falls into the water, a positioning object located near the place where the person fell into the water is ejected. By binding the positioning function of the person who fell into the water to the ship itself, problems such as search and rescue time lag and search and rescue position ambiguity caused by subjective factors are avoided. In addition, the use of positioning objects can more accurately simulate the position changes of people after falling into the water, thereby improving the success rate of search and rescue.

[0049] In a specific embodiment, the information acquisition device 200 includes an image acquisition module, and the water drop location device further includes an image recognition module that is communicatively connected to the control module 100 and the image acquisition module;

[0050] The image acquisition module is used to acquire images within the target information acquisition area within a preset range from the ship at the acquisition time, and send them to the image recognition module;

[0051] The image recognition module is used to receive and recognize an image, and send the recognition result to the control module 100;

[0052] The control module 100 is further configured to determine a matching target projectile device based on a target information acquisition area of ​​a target image corresponding to the recognition result in response to the recognition result indicating that the target object is in a state of falling into water.

[0053] Specifically, the information acquisition device 200 can be an image acquisition module, which performs real-time image acquisition of the area surrounding the ship and uses an image recognition module (for example, AI recognition) to identify each acquired image. When it is recognized that the image includes a person falling into the water, the corresponding target projectile device is determined by the acquisition direction of the target image, and the target projectile device is controlled to project a positioning object to track the position of the person falling into the water.

[0054] Among them, when it is identified that the person in the image is not in the clamping area, it can be considered that a person has fallen into the water. It can also be further judged whether it is a state of a person falling into the water to avoid judging normal diving, swimming and other behaviors as falling into the water and causing panic. For example, the state of falling into the water can be the state of the person in the air before falling into the water in the collected image, or it can be the state of struggling after falling into the water, or it can be the state of the whole process from falling into the air to struggling after falling into the water in multiple consecutive images. This embodiment does not limit this.

[0055] This specific implementation method can accurately identify the state of a person falling into the water by using images, and timely eject the positioning object to accurately track the person falling into the water.

[0056] In a specific embodiment, the image acquisition module includes a camera;

[0057] The control module 100 is also used to determine the target information collection area according to the position information of the camera that captures the target image.

[0058] Specifically, multiple cameras can be deployed at different locations around the ship, and the camera locations can be flexibly adjusted according to ships of different sizes and types, such as Figure 2As shown, the projection range of multiple cameras can fully cover the preset range of vision outside the ship (for example, the vision within 10 meters). For example, for a multi-layer cruise ship, in order to achieve the outer side of the cruise ship, the cameras can be arranged around the deck where the lowest outdoor area of ​​the ship is located at a preset interval for full ship deployment, such as Figure 3 As shown, the outdoor area of ​​the lowest level of the cruise ship is the outdoor corridor A, the cameras are arranged above the corridor and arranged along the entire ship, and the projectile device 300 is arranged on the side below the corridor; Figure 4 As shown, the superstructure of the cruise ship adopts an outward convex structure, and the outdoor area of ​​the lowest level is the cabin balcony B. The camera is arranged below the balcony on the lowest level and arranged along the entire ship, and the projectile device 300 is arranged on the side of the deck below the balcony.

[0059] This specific implementation method sets up multiple cameras to fully cover the preset range of vision outside the ship, so as to timely identify the status of people falling into the water in various directions, and timely throw positioning objects to accurately track the position of the people falling into the water.

[0060] In one embodiment, the positioning object includes a first entity and a second entity;

[0061] The first entity and the second entity have different densities;

[0062] The first entity and the second entity are both dummy models.

[0063] Specifically, due to the complex wind and wave conditions at sea, the situations of people falling into the water are diverse. For example, whether the person can swim, whether he deliberately jumps into the sea, whether he is drunk, etc. will affect the movement trajectory after falling into the water. Therefore, two positioning entities (i.e., the first entity and the second entity) are provided in each projectile device 300. Among them, in order to accurately simulate the movement trajectory of the person falling into the water floating with the waves, the positioning entity can be set to a dummy model with the same volume and shape as an adult male, and one dummy is made of a material with a density lower than the water density (e.g., seawater) in the waters where the ship is located, and the other dummy is filled with a material with a higher density inside so that it can sink in the water. When a person falls into the water, the target projectile device immediately starts the projectile device to throw the two dummies out of the ship at the same time.

[0064] After the dummies are thrown overboard, the dummy with a density lower than that of seawater floats on the sea surface and drifts with the waves, simulating the movement of the passengers falling into the water with the surges. The dummy with a density higher than that of seawater provides an original "anchor point" for the falling-in location. Based on the positions of the two dummies, the search and rescue range of the fallen passengers can be accurately determined, thereby improving the success rate of the search and rescue.

[0065] In a specific embodiment, a first wireless location tracker is provided in the first entity, and a second wireless location tracker is provided in the second entity;

[0066] The control module 100 is in communication connection with the first wireless positioning tracker and the second wireless positioning tracker;

[0067] The first wireless positioning tracker is used to send the first location information of the first entity to the control module 100;

[0068] The second wireless positioning tracker is used to send the second location information of the second entity to the control module 100;

[0069] The control module 100 is further configured to determine a water-falling range of the target object based on the first position information and the second position information.

[0070] Specifically, both positioning entities are provided with positioning trackers which are in communication connection with the control module 100, and the positions of the two positioning entities can be sent to the control module 100 in real time, so that search and rescue personnel can search and rescue the person who falls into the water according to the real-time positioning information.

[0071] In a specific embodiment, the control module 100 is communicatively connected to a control system of a ship's wheelhouse;

[0072] The control module 100 is also used to send an alarm signal to the control system.

[0073] Specifically, in order to further carry out rapid warning and rescue of people who fall into the water, by communicating with the control module 100 and the control system of the ship's cab, when a person who falls into the water is identified, an alarm signal of a person falling into the water is immediately sent to the cab, so that the crew can carry out rescue in time.

[0074] This embodiment uses information collection equipment to perform real-time monitoring of the area surrounding the ship. When a person falls into the water, a positioning object located near the place where the person fell into the water is ejected. By binding the positioning and alarm functions of the person who fell into the water to the ship itself, problems such as search and rescue time lag and search and rescue position ambiguity caused by subjective factors are avoided. In addition, the use of positioning objects can more accurately simulate the position changes of people after falling into the water, thereby improving the success rate of search and rescue.
