Description

Technical Field

[0001] The present application relates to the technical field of electronic digital data processing, and in particular to a device for adjusting the safe navigation distance of ships around an offshore platform, and also to a method. Background Art

[0002] Due to the characteristics of large inertia, strong nonlinearity and model uncertainty of ships, as well as factors such as wind disturbance at sea, ship drivers will maintain a certain safe distance from other ships or other obstacles according to the maneuvering characteristics of their own and other ships to avoid collision risks. For obstacles of different types, speeds and maneuvering performances in different environments, it is crucial to master the safe distance maintained from the ship to make correct avoidance decisions.

[0003] At present, most autonomous safety distance studies use safety warning circles to represent safety distances. Due to the maneuverability of ships, it is obvious that the safety distances required for ships in different directions or under different circumstances are not the same, and the safety distances for obstacles such as dynamic ships and static anchored ships are also different. Summary of the invention

[0004] Through research, the inventors found that due to the special working requirements of the offshore platform, it is necessary to set a fixed position in the ocean to operate, which puts strict requirements on the navigation of ships. If the ship driver can receive the position signal of the offshore platform in advance, dangerous situations during navigation can be greatly avoided.

[0005] The purpose of the present application is to provide a device and method for adjusting the safe distance for ships passing around an offshore platform, and to solve the technical problem that the prior art cannot provide a device for dynamically adjusting the safe distance between passing ships and offshore platforms through data feedback components and distance response components.

[0006] According to one aspect of the present application, a device for adjusting the safe navigation distance of ships around an offshore platform is provided, including an adjustment component, the adjustment component including a data feedback component, and a distance response component data-connected to the data feedback component; the distance response component includes at least a first distance response module and a second distance response module, and a telescopic column is connected between the first distance response module and the second distance response module.

[0007] In some embodiments, the first distance response module and the second distance response module both include a mounting component and a response component detachably connected to the mounting component.

[0008] In some embodiments, the mounting assembly includes a first mounting plate, a buffer block, and a second mounting plate, wherein the buffer block is flexibly connected between the first mounting plate and the second mounting plate.

[0009] In some embodiments, the first mounting plate is disposed in parallel with the second mounting plate.

[0010] In some embodiments, the response component includes a bearing base, a rotating wheel and a connecting block, the connecting block is fixedly connected to the bearing base, and the rotating wheel is rotatably connected to the bearing base.

[0011] In some embodiments, the support base is also electrically connected to a rotation speed measuring instrument for measuring the rotating wheel, and the rotation speed measuring instrument data is connected to the data feedback component.

[0012] In some embodiments, the first distance response module and the second distance response module are both slidably connected to the offshore platform.

[0013] In some embodiments, the peripheral side of the offshore platform is electrically connected to at least one set of the data feedback components.

[0014] According to another aspect of the present application, a method for adjusting the safe navigation distance of ships around an offshore platform is provided, the method being executed by a processor and comprising:

[0015] Obtain electronic chart signals of passing ships within 100 to 200 nautical miles around the target offshore platform;

[0016] Based on the electronic chart signal, the rotation speed of the wheels of the first distance response module and the second distance response module corresponding to the passing ship is obtained. When the rotation speed reaches the preset rotation speed value, the telescopic column will execute the movement of the first distance response module and the second distance response module. When the length of the telescopic column reaches the preset length, the data feedback component is triggered to execute the distance alarm to disperse the passing ships that are too close;

[0017] After the alarm signal is issued, a cyclic alarm is executed until the passing ship is at a safe distance.

[0018] Compared with the prior art, the present application realizes the distance alarm between the ship and the offshore platform through data feedback components and distance response components; further, through the cooperation of the rotor and the tachometer, the ship's sailing speed and distance can be judged in advance through wave fluctuations, and distance alarms can be made accordingly, ultimately achieving rapid early warning and adjustment of the safe distance between the offshore platform and the surrounding navigable ships.

DETAILED DESCRIPTION

[0026] The following will be combined with the attached examples of the present application Figure 1-4 The technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0027] Application Overview

[0028] Since the existing safety distance for maritime navigation is mostly represented by safety warning circles, it is obvious that the safety distance of ships to target objects in different directions or different sea areas is not the same. At the same time, when ships are sailing in the sea, there are certain risks in controlling the safety distance of offshore platforms. This application focuses on the safety distance of offshore platforms, and through data feedback components and distance response components, targeted warnings and adjustments are made to the safety distances of surrounding ships, so as to improve the navigation safety of ships around offshore platforms.

[0029] Example 1

[0030] The present embodiment provides a device for adjusting the safe distance of ships passing through the periphery of an offshore platform, including an adjustment component, the adjustment component including a data feedback component 14, and a distance response component data-connected to the data feedback component 14. The adjustment component in the present embodiment includes at least the data feedback component 14 and the distance response component, and in other sea areas, or when facing different offshore platforms, it may also include a route guidance module, the route guidance module is configured with a route calculation unit and a route planning unit, the route calculation unit is configured with a calculation model, and the route planning unit is configured with a planning model.

[0031] Furthermore, the distance response component includes at least a first distance response module and a second distance response module, and a telescopic column 8 is connected between the first distance response module and the second distance response module. In detail, the telescopic column 8 is telescopic in the vertical space, and is jointly controlled by the first response module and the second response module. The joint control can more accurately perform telescopic length control. At the same time, in order to ensure smooth telescopic operation, the connection method of the connecting column 8 in this embodiment adopts a flexible connection.

[0032] In some embodiments, the first distance response module and the second distance response module both include a mounting assembly 10 and a response assembly 9 detachably connected to the mounting assembly 10, the mounting assembly 10 includes a first mounting plate 1, a buffer block 2 and a second mounting plate 3, the buffer block 2 is flexibly connected between the first mounting plate 1 and the second mounting plate 3, wherein the first mounting plate 1 is arranged in parallel with the second mounting plate 3. In detail, in order to ensure the efficient operation of the device of this embodiment, the first mounting plate 1 will first be connected to the peripheral side of the support column 12 of the offshore platform 11, such as Figure 2 As shown. Next, since it is fixed in the sea, a buffer block 2 is added to reduce the impact of waves on the first mounting plate 1 caused by wind or rain in the sea. Finally, the second mounting plate 3 is connected to the buffer block 2, and further connected to the response component 9 to achieve a flexible connection. It should be noted that in some possible implementation scenarios, an elastic pad 4 can also be set between the response component 9 and the mounting component 10 to further improve the buffering effect.

[0033] In some embodiments, the response component 9 includes a bearing base 5, a rotating wheel 6 and a connecting block 7, wherein the connecting block 7 is fixedly connected to the bearing base 5, and the rotating wheel 6 is rotatably connected to the bearing base 5. The bearing base 5 is also electrically connected to a rotation speed measuring instrument for measuring the rotating wheel 6, and the data of the rotation speed measuring instrument is connected to the data feedback component 14. In detail, when there are multiple ships sailing around the offshore platform 11, since the distance between the ship and the offshore platform 11 cannot be directly measured, there will be scratches or route obstacles. At this time, the inventor has found through long-term front-line operations that the wave ripples generated during the navigation of the ship can be used to adjust the distance of the navigable ship and to warn. When one of the ships enters the vicinity of the offshore platform 11, due to its own power and weight, it will generate water ripples with itself as the origin and a certain radius. When the water ripples meet a hard target, a short-term impact will occur, and this impact is obtained by converting potential energy into kinetic energy. Then, when the wheel 6 in the response component 9 is exposed to the impact of the ripples, it will rotate. It can be understood that the speed of rotation is determined by the frequency of the ripples, and the frequency of the ripples is determined by the distance between the ship and the offshore platform 11. The closer the distance, the higher the frequency of the ripples, and the more impacts there are. At this time, the rotation speed of the wheel 6 will become faster and faster. When the rotation speed of the wheel 6 is measured by the speed meter to reach the preset value, the response component 9 will send a signal, which will trigger the telescopic column 8 to perform the telescopic operation, wherein the telescopic column 8 is telescoped by the driving member in the connecting block 7. The driving member includes at least an underwater power supply, a bidirectional drive motor, and a coupling connecting the end of the telescopic column 8 and the output end of the bidirectional drive motor, and a drive guide rod installed on the coupling. It can be understood that the aforementioned structures will be waterproofed.

[0034] Reference Figure 2 When the telescopic column 8 is extended to the preset length, the response component 9 will send an alarm signal to the data feedback component 14. At this time, the data feedback component 14 will issue an alarm broadcast and send a stop or turn notification to the control system of the corresponding target navigable ship. This process stops until the corresponding ship turns or enters a safe distance.

[0035] Example 2

[0036] The technical features in this embodiment are basically the same as the technical features described in Example 1. The same technical features and technical solutions will not be repeated here. Only the differences between Example 2 and Example 1 are described here. The first distance response module and the second distance response module are both slidably connected to the offshore platform 11. It can be understood that in order to ensure more adaptability to different offshore platforms 11 or different depths, the connection method of the sliding connection can quickly solve this problem. Of course, other connection methods can also be selected, such as detachable connection. It should be noted that the sliding connection method in this embodiment is to install a slide rail between the first mounting plate 1 and the support column 12 to achieve relative sliding.

[0037] In some embodiments, the peripheral side of the offshore platform 11 is electrically connected to at least one set of data feedback components 14. It is understandable that the data feedback components 14 are at least arranged on a peripheral surface of the offshore platform 11, and in a possible embodiment, the data feedback components 14 can also be connected to each peripheral surface.

[0038] Exemplary Methods

[0039] The present application also provides a method for adjusting the safe navigation distance of ships around an offshore platform, which is executed by a processor, and the processor can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc.

[0040] The method includes: obtaining the electronic chart signal of the passing ship within 100 to 200 nautical miles around the target offshore platform. It should be noted that the electronic chart signal at least includes the ship AIS signal; based on the electronic chart signal, obtaining the rotation speed of the first distance response module and the second distance response module of the corresponding passing ship, when the rotation speed reaches the preset rotation speed value, the telescopic column will execute the movement of the first distance response module and the second distance response module, and when the length of the telescopic column reaches the preset length, the data feedback component is triggered to execute the distance alarm to disperse the passing ship that is too close; after the alarm signal is issued, the cyclic alarm is executed until the passing ship is at a safe distance. It can be understood that the selection of 100 to 200 nautical miles is to make a distance judgment in advance. At the same time, in order to avoid making an erroneous judgment, that is, judging the wrong corresponding navigable ship information, the fuzzy positioning of the navigable ship position will be realized based on the electronic chart information and GPS, thereby avoiding the erroneous determination of the navigable ship that needs to be adjusted in the subsequent operation.
