Description

Technical Field

[0001] This application relates to the field of explosion-proof lighting technology, specifically to an explosion-proof lighting method, device, storage medium, and electronic equipment. Background Technology

[0002] Explosion-proof lights are lighting fixtures used in hazardous locations containing flammable gases and dust. They prevent potential internal arcs, sparks, and high temperatures from igniting the surrounding flammable materials and dust, thus meeting explosion-proof requirements. For example, ships transporting oil are considered hazardous locations in flammable and explosive environments, and explosion-proof lights are widely used on these vessels, especially during nighttime navigation, to meet their lighting needs.

[0003] When ships navigate at night, to avoid collisions due to low visibility, the common method is to use navigation lights to help other vessels know the ship's course, position, and size, allowing them to take appropriate evasive action. However, this method only provides other vessels with approximate course and position information, resulting in low precision in avoidance. Summary of the Invention

[0004] To improve the accuracy of obstacle avoidance, this application provides an explosion-proof lighting method, device, storage medium, and electronic device.

[0005] The first aspect of this application provides a method for providing explosion-proof lighting, specifically including: Obtain the target distance between other vessels and the target vessel; If the other vessels are sailing in the same direction as the target vessel, a first illumination spot is determined based on the target distance, and the first illumination spot is projected onto a first area by a preset explosion-proof lamp. The first area is the water surface area between the target vessel and the other vessels in the sailing direction. If the other vessels are sailing in the opposite direction to the target vessel, and the other vessels are sailing towards the target vessel, then a second illumination spot is determined according to the target vessel's target route, and the second illumination spot is projected onto a second area through the explosion-proof lamp. The second area is the water surface area directly in front of the target vessel.

[0006] By adopting the above technical solution, when other vessels are present on the water, if the other vessels are traveling in the same direction as the target vessel and there is a risk of rear-end collision, then a first illumination spot with a reasonable range is determined based on the target distance between the other vessels and the target vessel. This spot is then projected onto the first area, i.e., the water surface area between the other vessels and the target vessel, through explosion-proof lights. This creates a reasonable illumination area between the two vessels, which helps to accurately avoid collisions and prevent rear-end collisions. If the other vessels are traveling in the same direction as the target vessel and are heading towards each other, there is a risk of a bow-to-bow collision or a bow-to-hull collision when the two vessels pass each other. In this case, the target vessel's target course is projected onto the second area, i.e., the water surface area directly in front of the target vessel, in the form of a second illumination spot. This allows the navigator of the target vessel to accurately know the target vessel's course through the light spot on the water surface, thus enabling precise avoidance and preventing collisions between the vessels.

[0007] Optionally, determining the first illumination spot based on the target distance and projecting the first illumination spot onto the first area using a preset explosion-proof lamp specifically includes: If the target vessel is a vessel behind, then the initial illumination spot and the initial projection area are determined based on the target distance; Calculate the speed difference between the first speed of the target vessel and the second speed of the other vessels. If the first speed is greater than the second speed, increase the length of the initial illumination spot according to the speed difference to obtain the first illumination spot. The initial projection area is defined as the first area, and the first illumination spot is projected onto the first area by a preset explosion-proof lamp; If the first ship speed is not greater than the second ship speed, then the initial illumination spot is determined as the first illumination spot, and the initial projection area is moved backward to obtain the first area; The first illumination spot is projected onto the first area by a preset explosion-proof lamp.

[0008] By adopting the above technical solution, when the target vessel is traveling in the same direction as other vessels and is the vessel following behind, and the first vessel speed is greater than the second vessel speed, the target distance between the target vessel and other vessels ahead will continuously decrease. To ensure a good lighting field of view in front of the target vessel, the lighting field of view must also be moved forward accordingly. Based on the speed difference, the length of the initial lighting spot is increased to obtain the first lighting spot, which is then projected onto the first area. This achieves forward movement of the lighting field of view, avoiding situations where the lighting field of view cannot keep up with excessive speed. If the first vessel speed is not greater than the second vessel speed, it means that the target distance between the target vessel and other vessels ahead and behind will not decrease, and may even increase, making the probability of needing to avoid it relatively small. In this case, the initial lighting spot remains unchanged and is determined as the first lighting spot, and the initial projection area is moved backward to obtain the first area, making the illumination area closer to the target vessel itself, thus facilitating the driver's observation of whether there are obstacles such as reefs ahead.

[0009] Optionally, determining the second illumination spot based on the target route of the target vessel specifically includes: Based on the target route of the target vessel, the projection profile of the illumination spot in the length direction is determined, and the width of the target vessel is determined as the initial projection width; If the target distance is less than the warning distance, the initial projection width is increased according to the sum of the speeds of the target vessel and the other vessels to obtain the first projection width; The second illumination spot is determined based on the projection profile and the first projection width; If the target distance is not less than the warning distance, then when the sum of the ship speeds exceeds the ship speed threshold, the initial projection width is increased according to the difference between the sum of the ship speeds and the ship speed threshold to obtain the second projection width; The second illumination spot is determined based on the projection profile and the second projection width.

[0010] By adopting the above technical solution, after determining the projection outline and initial projection width, when the target distance is small, in order to improve the lighting warning effect and reduce the collision risk, the initial projection width is increased according to the sum of ship speeds to obtain the first projection width, and then the second lighting spot is determined. This ensures that when the second spot is projected onto the second area, it can not only provide accurate heading information for other ships, but also have a wider lighting warning range. If the target distance is large, the initial projection width is increased according to the difference between the sum of ship speeds and the ship speed threshold, and the second lighting spot is finally determined, thereby improving the accuracy of avoidance.

[0011] Optionally, the method further includes: Determine whether the target vessel and the other vessels are in a state of hull overlap. If so, determine the third illumination spot based on the distance between the target vessel and the other vessels. The third illumination spot is projected onto the third area by a backup explosion-proof lamp. The third area is the water surface area between the hull of the target vessel and the hulls of the other vessels. If any other vessel enters the third illumination spot, the color of the third illumination spot will be adjusted to red to warn the other vessel.

[0012] By adopting the above technical solution, if the target vessel is in a state of hull overlap with other vessels, it indicates that they are passing each other during navigation, which can be understood as a passing situation between vehicles. Then, a reasonable third illumination spot is determined based on the distance between the vessels, and the third illumination spot is projected onto the third area using explosion-proof lights. Once other vessels approach the target vessel, the color of the third illumination spot is adjusted to red, thereby effectively preventing the target vessel from colliding with the sides of other vessels.

[0013] Optionally, the method further includes: If the other vessels are sailing in the same direction as the target vessel and the target vessel is the preceding vessel, determine whether the target vessel and the other vessels are in the same fleet. If the other vessels belong to the same fleet as the target vessel, the second illumination spot will be projected onto the first area by the explosion-proof lamp; If the other vessels do not belong to the same fleet as the target vessel, the first illumination spot is projected onto the first area by the explosion-proof lamp.

[0014] By adopting the above technical solution, if other vessels belong to the same fleet as the target vessel, the target route is preferentially projected as a second illumination spot onto the area between the target vessel and the other vessels, thereby reducing the risk of other vessels deviating from their course, keeping them close to the target vessel ahead, and avoiding falling behind the fleet. It also provides further illumination for other vessels behind. If other vessels do not belong to the same fleet as the target vessel, the first illumination spot is preferentially projected onto the first area, providing lighting warnings to avoid rear-end collisions.

[0015] Optionally, the method further includes: The water surface ripple value is obtained through a float sensor. If the water surface ripple value exceeds a ripple threshold, a first three-dimensional pattern corresponding to the first illumination spot is projected onto the top of the first area using a preset holographic projection drone; or The second 3D pattern corresponding to the second illumination spot is projected onto the area directly above the second region using a pre-set holographic projection drone; or The third stereoscopic pattern corresponding to the third illumination spot is projected onto the top of the third region by a pre-set holographic projection drone.

[0016] By adopting the above technical solution, if the water surface fluctuation value exceeds the fluctuation threshold, it indicates that the current water surface fluctuation amplitude is large, which will affect the integrity and visibility of the illumination spot projected onto the water surface. Therefore, by using a holographic projection drone to project the three-dimensional pattern of the corresponding illumination spot onto the corresponding area of ​​the water surface, even if the illumination spot is affected, it can still ensure that other ships can accurately avoid it.

[0017] Optionally, the step of acquiring water surface fluctuation values ​​via a float sensor, if the water surface fluctuation value exceeds a fluctuation threshold, further includes: When the extended course of the target vessel intersects with the extended course of other vessels, the duration during which the course of the other vessels remains unchanged is recorded. If the duration exceeds the duration threshold, the holographic projection drone will project a target 3D pattern onto the area above the water surface directly in front of the other vessel. The target 3D pattern is a directional guidance pattern that is away from the target vessel.

[0018] By adopting the above technical solution, if the duration exceeds the time threshold, it means that other ships have not changed course for a long time. In this case, a holographic projection drone can project a directional guidance pattern away from the target ship onto the airspace above the water directly in front of the other ships. This makes it easy for the drivers of other ships to observe the directional guidance, adjust their course in time, and make precise avoidance to prevent collisions.

[0019] A second aspect of this application provides an explosion-proof lighting device, specifically comprising: The distance acquisition module (11) is used to acquire the target distance between other ships and the target ship; The first projection module (12) is used to determine the first illumination spot according to the target distance if the other ships are sailing in the same direction as the target ship, and to project the first illumination spot to the first area through a preset explosion-proof lamp. The first area is the water surface area between the target ship and the other ships in the sailing direction. The second projection module (13) is used to determine a second illumination spot according to the target route of the target vessel if the other vessels are sailing in opposite directions to the target vessel and the other vessels are sailing towards the target vessel, and to project the second illumination spot to a second area through the explosion-proof lamp. The second area is the water surface area directly in front of the target vessel.

[0020] By adopting the above technical solution, after the distance acquisition module obtains the target distance, the first projection module determines the first illumination spot when other ships are sailing in the same direction as the target ship, and projects the first illumination spot onto the first area through an explosion-proof light. Finally, the second projection module determines the second illumination spot when other ships are sailing in opposite directions and heading towards the target ship, and projects it onto the second area through an explosion-proof light, thereby improving the accuracy of avoidance between other ships and the target ship.

[0021] In summary, this application includes at least one of the following beneficial technical effects: When other vessels are present on the water, if they are traveling in the same direction as the target vessel and there is a risk of rear-end collision, a first illumination spot of reasonable range is determined based on the target distance between the other vessels and the target vessel. This spot is then projected onto the first area, i.e., the water surface area between the other vessels and the target vessel, through explosion-proof lights. This creates a reasonable illumination area between the two vessels, facilitating precise avoidance and preventing a rear-end collision. If the other vessels are traveling in the same direction as the target vessel and are heading towards each other, there is a risk of a bow-to-bow collision or a bow-to-hull collision when the two vessels pass each other. In this case, the target vessel's target course is projected onto the second area, i.e., the water surface area directly in front of the target vessel, in the form of a second illumination spot. This allows the navigator of the target vessel to accurately determine the target vessel's course through the illumination spot on the water surface, enabling precise avoidance and preventing a collision.

[0027] See Figure 1 This application discloses a flowchart of an explosion-proof lighting method, which can be implemented using a computer program or run on an explosion-proof lighting device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application, specifically including: S101: Obtain the target distance between other vessels and the target vessel.

[0028] Specifically, the target vessel is a vessel equipped with a ship control platform, which is used to manage and monitor various equipment and systems within the target vessel. An explosion-proof lighting method disclosed in this application is applied to this ship control platform. The ship control platform can be a server, which can be a standalone physical server or a server cluster consisting of multiple physical servers. In other embodiments, the ship control platform can also be a terminal, such as a personal computer (PC) or other electronic device.

[0029] Marine radar is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves and receives those reflected from targets. By analyzing the reflected waves, the target's position, speed, and direction can be determined. Marine radar installed on a target vessel can detect the presence of other vessels within a preset range. If other vessels are present, their positions can be determined, thus establishing the target distance between the target vessel and the target vessel. It should be noted that marine radar can also acquire the headings and speeds of other vessels. Furthermore, target distance is the straight-line distance between the target vessel and other vessels.

[0030] S102: If other vessels are sailing in the same direction as the target vessel, the first illumination spot is determined according to the target distance, and the first illumination spot is projected to the first area through a preset explosion-proof lamp.

[0031] Specifically, the illumination spot is the light pattern projected onto the water surface by the explosion-proof lamp. The first area is the water surface area between the target vessel and other vessels in the direction of navigation. After determining the target distance, it is necessary to determine whether the target vessel and other vessels are traveling in the same direction. One feasible method is to obtain the target vessel's heading through BeiDou satellite navigation and compare it with the headings of other vessels. If the two headings are consistent, for example, in the same waterway, if the target vessel's heading is east-northeast and the other vessels' headings are also east-northeast, then it is determined that the target vessel and other vessels are traveling in the same direction. It should be noted that in the case of traveling in the same direction, the target vessel can be behind (the vessel following the other vessel) or ahead (the vessel preceding the other vessel).

[0032] Furthermore, the first illumination spot is determined based on the target distance. One feasible implementation is as follows: if the target vessel is the following vessel, the initial illumination spot and the initial projection area are determined based on the target distance. Calculate the speed difference between the first speed of the target vessel and the second speed of other vessels. If the first speed is greater than the second speed, increase the length of the initial illumination spot according to the speed difference to obtain the first illumination spot. The initial projection area is defined as the first area, and a first illumination spot is projected onto the first area using a preset explosion-proof lamp; If the first ship speed is not greater than the second ship speed, then the initial illumination spot is determined as the first illumination spot, and the initial projection area is moved back to obtain the first area; The first illumination spot is projected onto the first area by a preset explosion-proof lamp.

[0033] Specifically, when ships are traveling in the same direction, the target distance is the distance between the fore and aft vessels. If the target vessel is the following vessel, the length of the illumination spot and the projection angle of the explosion-proof lamp corresponding to the target distance are matched from the projection parameter matching table. The projection angle of the explosion-proof lamp is the angle between the explosion-proof lamp beam and the water surface. The larger the target distance, the larger the corresponding illumination spot length. Then, a rectangle with a length equal to the illumination spot length and a width equal to the width of the target vessel is determined as the initial illumination spot. In addition, the area where the illumination spot is located at this explosion-proof lamp projection angle is determined as the initial projection area.

[0034] Furthermore, the first speed of the target vessel is obtained through a speed sensor. If the first speed is greater than the second speed of other vessels, it indicates that the target distance between the target vessel and other vessels ahead will continuously decrease. To ensure a good illumination field of view in front of the target vessel, the illumination field of view must also be moved forward accordingly. The difference between the first and second speeds is calculated to obtain the speed difference value. Then, a preset length increase matching table is used to match the increase in the length of the illumination spot corresponding to the speed difference. The length of the initial illumination spot is increased by the illumination spot length increase value to obtain the first illumination spot. Simultaneously, the illumination angle of the explosion-proof lamp remains unchanged, thus defining the initial projection area as the first region. In other embodiments, the length of the initial illumination spot can also be kept constant, and the initial projection area can be moved forward relative to the target vessel to obtain the first region. The forward movement amount can be obtained by matching the speed difference value; the larger the speed difference value, the larger the forward movement amount. The current projection area is repeatedly moved forward at preset time intervals. The preset time interval is also determined by matching the speed difference value; the larger the speed difference value, the smaller the preset time interval. One possible way to achieve this is by adjusting the angle of the explosion-proof lamp head to adjust the projection angle of the explosion-proof lamp.

[0035] If the first ship speed is not greater than the second ship speed, it means that the target distance between the target ship and other ships will not decrease, or may even increase, and the probability of needing to avoid it is small. Therefore, keep the initial illumination spot unchanged and determine it as the first illumination spot. Move the initial projection area backward to obtain the first area, so that the illumination area is closer to the target ship, which makes it easier for the target ship's driver to observe whether there are obstacles such as reefs ahead.

[0036] Finally, the explosion-proof lights installed on the target vessel project the first illumination spot onto the first area, thereby creating a relatively reasonable illumination area between the target vessel and other vessels, enabling the target vessel to make accurate avoidance maneuvers and avoid collision with the vessel in front.

[0037] S103: If other vessels are sailing in the opposite direction to the target vessel and are sailing towards the target vessel, then the second illumination spot is determined according to the target vessel's target route, and the second illumination spot is projected into the second area by explosion-proof lights.

[0038] Specifically, the target route is the trajectory of the target vessel from its current position to its destination, which can be obtained through the BeiDou Navigation Satellite System. The second area is the water surface area directly in front of the target vessel. If other vessels are traveling in the opposite direction to the target vessel, and the position of the other vessels is determined to be ahead of the target vessel by marine radar, i.e., it is determined that the other vessels are traveling towards the target vessel, further, to avoid inaccurate avoidance angles by other vessels, which would increase the risk of collision between the two vessels, a second illumination spot is further determined based on the target route. One feasible method for determining this is: based on the target vessel's target route, determine the projection profile of the illumination spot in the length direction, and determine the width of the target vessel as the initial projection width; If the target distance is less than the warning distance, the initial projection width is increased based on the sum of the speeds of the target vessel and other vessels to obtain the first projection width; The second illumination spot is determined based on the projection profile and the first projection width; If the target distance is not less than the warning distance, then when the sum of the ship speeds exceeds the ship speed threshold, the initial projection width is increased according to the difference between the sum of the ship speeds and the ship speed threshold to obtain the second projection width. The second illumination spot is determined based on the projection profile and the second projection width.

[0039] Specifically, such as Figure 2 As shown, starting from the current position of the target vessel, a curve of a preset length is extracted from the trajectory curve of the target route as the projection outline of the light spot to be projected, and the width of the target vessel is determined as the initial projection width. Next, the target distance is compared with the warning distance, which is the minimum safe distance between vessels traveling in opposite directions. If the target distance is less than the warning distance, it indicates that the target vessel is too close to other vessels, and the risk of collision is high. Therefore, the sum of the speeds of the target vessel and other vessels is calculated. The larger the sum of the speeds, the faster the target vessel and other vessels are approaching. To reduce the risk of collision and warn other vessels to maintain a safe distance from the target vessel, the projection width adjustment amount corresponding to the sum of the speeds is matched from the width adjustment amount matching table. The width adjustment amount matching table includes different sums of speeds and their corresponding projection width adjustment amounts. The larger the sum of the speeds, the larger the corresponding projection width adjustment amount. Then, the initial projection width is increased by the projection width adjustment amount to obtain the first projection width, making the coverage of the illumination spot wider and the warning range for other vessels larger. Finally, based on the first projection width and the projection outline, the second illumination spot is determined. It should be noted that, in the embodiment of the application, the projection width adjustment is increased on the side of the initial projection width closer to other ships.

[0040] If the target distance is not less than the warning distance, it means that other vessels are still far from the target vessel. Then, it is determined whether the sum of their speeds exceeds a speed threshold. If it does, it means that although the two vessels are far apart, they are approaching too quickly. Based on the difference between the sum of their speeds and the speed threshold, a projection width increment corresponding to the difference is matched from a preset width increment matching table. The initial projection width is then increased based on this increment to obtain the second projection width. Finally, the second illumination spot is determined based on the second projection width and the projection profile.

[0041] Furthermore, a second illumination spot is projected onto a second area using explosion-proof lights. This second area can be determined based on the target distance; the greater the target distance, the farther the second area should be from the target vessel. Ultimately, this projects the target vessel's course onto the water surface as an illumination spot, providing not only illumination for the target vessel but also accurately indicating its course to other vessels, allowing them to make precise avoidance maneuvers and reducing the risk of collision.

[0042] See Figure 3 This application discloses a flowchart of another explosion-proof lighting method, which can be implemented using a computer program or run on an explosion-proof lighting device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application, specifically including: S201: Obtain the target distance between other vessels and the target vessel.

[0043] S202: If other vessels are sailing in the same direction as the target vessel, the first illumination spot is determined according to the target distance, and the first illumination spot is projected to the first area through a preset explosion-proof lamp.

[0044] S203: If other vessels are sailing in the opposite direction to the target vessel and are sailing towards the target vessel, then the second illumination spot is determined according to the target vessel's target route and the second illumination spot is projected into the second area by explosion-proof lights.

[0045] For details, please refer to steps S101-S103, which will not be repeated here.

[0046] S204: When other vessels are sailing in the same direction as the target vessel and the target vessel is the preceding vessel, determine whether the target vessel and the other vessels are in the same fleet.

[0047] Specifically, refer to step S102 for determining whether other vessels are sailing in the same direction as the target vessel. If it is determined that other vessels are sailing in the same direction as the target vessel, further, based on the position information of the other vessels, if the other vessels are behind the target vessel, then the target vessel is determined to be the preceding vessel. Next, the other vessels are photographed using a camera, and the logos or company names on the hulls of the other vessels in the photos are identified and extracted. If the logo of the other vessel matches the logo of the target vessel, or if the company name of the other vessel matches the company name of the target vessel, it indicates that they belong to the same fleet; otherwise, it is determined that they do not belong to the same fleet.

[0048] S205: If other vessels belong to the same fleet as the target vessel, a second illumination spot will be projected onto the first area using explosion-proof lights.

[0049] Specifically, if other vessels belong to the same convoy as the target vessel, it means they share the same destination and route. Therefore, a second illumination spot is determined based on the target vessel's target route. This involves capturing a pre-defined length of the target route curve from the target vessel's current position and combining this with the target vessel's width to determine the second illumination spot. Finally, the second illumination spot is projected onto the first area using explosion-proof lights. This projects the target vessel's target route as an illumination spot onto the water surface behind the target vessel and in front of other vessels. In complex night navigation conditions, guided by the second illumination spot, vessels follow the target vessel's route, reducing the risk of other vessels veering off course and ensuring close following of the target vessel ahead, preventing them from falling behind the convoy. Furthermore, the second illumination spot also provides additional illumination for other vessels behind. It should be noted that as the target vessel continues to move forward, the target route shortens, and the second illumination spot changes in real time.

[0050] S206: If other vessels do not belong to the same fleet as the target vessel, a first illumination spot shall be projected onto the first area by an explosion-proof light.

[0051] Specifically, if other vessels do not belong to the same fleet as the target vessel, there is no need to guide their course. Based on the target distance, a first illumination spot with a rectangular light pattern is determined and projected onto the water surface between the target vessel and the other vessels. This serves to warn other vessels behind to pay attention to the distance between themselves and the vessel in front, so as to avoid collisions. For details, please refer to step S102, which will not be repeated here.

[0052] In other embodiments, it is determined whether the target vessel and other vessels are in a state of hull overlap. If so, the third illumination spot is determined based on the distance between the target vessel and other vessels. The third illumination spot is projected onto the third area by the backup explosion-proof light. The third area is the water surface area between the hull of the target vessel and the hulls of other vessels. If other vessels enter the third illumination spot, the color of the third illumination spot will be adjusted to red to warn other vessels.

[0053] Specifically, in this embodiment, the ship-hull interleaving state refers to the situation where the target ship and other ships intersect during navigation. This may involve two ships with opposite directions interleaving or two ships with the same direction interleaving. The ship-to-ship distance refers to the distance between the side of the target ship and the side of other ships. One feasible method for determining the ship-hull interleaving state is as follows: An ultrasonic sensor is used to detect whether the bow of another ship enters the area on the side of the target ship's hull. If it does, the ship-hull interleaving state is determined. To avoid collisions between the side hulls of the target ship and other ships, a distance measuring sensor is used to obtain the ship-to-ship distance. Based on the ship-to-ship distance, the width of the third illumination spot corresponding to the ship-to-ship distance is matched from a width matching table. The overlap length between the target ship and other ships is determined as the length of the third illumination spot, ultimately determining a rectangular third illumination spot. Then, the distance value corresponding to the ship-to-ship distance is matched according to a distance matching table, i.e., the distance from the third illumination spot to the hull of other ships, thereby determining the third region from the water surface area between the hulls of the target ship and other ships. Finally, a third illumination spot is projected onto the third area using a backup explosion-proof light to alert other vessels to the distance between them and the target vessel, thus preventing a collision.

[0054] Once other vessels enter the third illumination spot, the color of the backup explosion-proof light is adjusted to red to warn other vessels that the distance between their hulls and the target vessel is too close, allowing them to adjust their course in time to avoid a collision.

[0055] In another embodiment, the water surface ripple value is obtained by a float sensor. If the water surface ripple value exceeds a ripple threshold, a first three-dimensional pattern corresponding to the first illumination spot is projected onto the top of the first area by a preset holographic projection drone; or The second 3D pattern corresponding to the second illumination spot is projected onto the top of the second area using a pre-set holographic projection drone; or The third stereoscopic pattern corresponding to the third illumination spot is projected onto the top of the third area using a pre-set holographic projection drone.

[0056] Specifically, such as Figure 2As shown, after the explosion-proof light projects the corresponding illumination spot onto the corresponding area, the water surface fluctuation value is acquired in real time through the float sensor. If the water surface fluctuation value exceeds the fluctuation threshold, it indicates that the current water surface fluctuation amplitude is large, and the clarity, integrity, and visibility of the first, second, or third illumination spot will be significantly affected, making it impossible for other ships to identify them, thus affecting the accurate avoidance between ships. Therefore, a cuboid with a cross-section corresponding to the rectangle of the first illumination spot is defined as the first 3D pattern, and then the first 3D pattern is projected onto the top of the first area using a holographic projection drone. Alternatively, a cube with a cross-section corresponding to the planar shape of the second illumination spot is defined as the second 3D pattern, and then the second 3D pattern is projected onto the top of the second area using a holographic projection drone. Or, a cuboid with a cross-section corresponding to the rectangle of the third illumination spot is defined as the third 3D pattern, and then the third 3D pattern is projected onto the top of the third area using a holographic projection drone, thus enabling other ships to make accurate avoidance maneuvers and maintain a safe distance from the target ship. Among them, holographic projection drones are drones that use holographic projection technology to present images.

[0057] In another embodiment, the water surface fluctuation value is obtained by a float sensor. If the water surface fluctuation value exceeds the fluctuation threshold, the method further includes: when the extended course of the target vessel intersects with the extended course of other vessels, the duration for which the course of other vessels remains unchanged is counted. If the duration exceeds the time threshold, a holographic projection drone will project a 3D pattern of the target onto the airspace above the water directly in front of other ships. The 3D pattern of the target will be a directional guide pattern that is far away from the target ship.

[0058] Specifically, the target 3D pattern is a directional guide pattern located away from the target vessel's hull. This directional guide pattern can be a three-dimensional arrow; for example, if the target vessel is to the right of other vessels, the target 3D pattern would be an arrow pointing to the left of the other vessels. If significant water surface fluctuations are detected, and the extended course of the target vessel intersects with that of other vessels, it indicates a potential collision if both vessels maintain their current course. Next, if the course of other vessels is monitored in real-time, and if the duration of their unchanged course exceeds a certain threshold, it indicates a slow avoidance response. In this case, the target 3D pattern is projected onto the water surface directly in front of the other vessels using a holographic projection drone. This makes the target 3D pattern easily visible to the crew of the other vessels, allowing them to adjust their course promptly for precise avoidance.

[0059] The implementation principle of the explosion-proof lighting method in this application embodiment is as follows: When other ships are present on the water surface, if the other ships are traveling in the same direction as the target ship and there is a risk of rear-end collision, then a first lighting spot with a reasonable range is determined based on the target distance between the other ships and the target ship, and the first lighting spot is projected onto the first area, that is, the water surface area between the front and rear of the other ships and the target ship, so that there is a reasonable lighting area between the other ships and the target ship, which helps to accurately avoid collisions. If the other ships are traveling in the same direction as the target ship and are heading towards each other, there is a risk of bow-to-bow collision or bow-to-hull collision when the two ships pass each other, then the target ship's target route is projected onto the second area, that is, the water surface area directly in front of the target ship, in the form of a second lighting spot, so that the driver of the target ship can accurately know the target ship's course through the light spot on the water surface, and thus make accurate avoidance to prevent collisions between the ships.
