Description

Technical Field

[0001] The present invention relates to a marine target abnormality warning system based on visualized situation display, and in particular to a marine target abnormality warning system based on visualized situation display applied in the field of abnormality warning. Background Art

[0002] For situation display, GIS, DIS, HLA and other systems or architectures are mainly used to design and implement situation display systems. In the document "Implementation of combat situation display system based on multi-layer Web technology", a system architecture framework of battlefield situation display system is established according to key technology CORBA standard, etc.; in the document "Research on framework and key technologies of general situation display system based on Qt", a system data organization model is established, a scene-view software architecture is proposed, a classified and hierarchical situation management mechanism is constructed, and the module functions are designed in detail; in the document "Research on situation display system in distributed combat simulation", a distributed combat situation display system structure is constructed by combining two-dimensional situation display with three-dimensional virtual battlefield.

[0003] However, due to the particularity of the marine environment compared to land, the trajectory of moving targets on the sea is difficult to control as accurately as on land, and there are fewer reference objects, which makes it easy for deviation to occur. For some large moving targets, when they deviate from the established route, they are likely to intersect with the routes of other moving targets. When two ships approach each other, due to restrictions such as water flow velocity and pressure, the two ships are likely to "attract" each other and cause a collision. When there are no other ships around, it is difficult to detect the deviation in time due to the lack of reference objects. In severe cases, it may even occur. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that in the prior art, after the target object deviates, it is difficult to detect in time, which easily leads to a collision between the two ships or a direct loss of connection.

On the one hand, when the distance between adjacent targets is relatively close, due to the sharing of information such as heading and speed between each other, it is convenient to detect the abnormality of the other party in time, so as to take corresponding measures to effectively avoid the collision of the two targets. On the other hand, when the distance between adjacent targets is relatively far, when deviation or loss of contact occurs, the location range can be narrowed through adjacent targets, thereby reducing the difficulty and time of search and rescue, and improving the safety of the lost target.

The self-diffusion chain includes a sealing pipe head fixedly connected to the mounting plate, a double-layer rope fixedly connected to the end of the sealing pipe head, and a collection chain fixedly connected to the end of the double-layer rope away from the sealing pipe head. The collection chain includes an extended chain body, multiple floats respectively fixedly connected to the extended chain body, and multiple tail deformation balls respectively fixedly connected to multiple ends of the extended chain body. The data acquisition module includes but is not limited to radar, flow rate sensor, water pressure sensor, and locator.

[0015] In summary, multiple targets sailing at sea can share information with each other, thus forming a self-service information chain. On the one hand, when the distance between adjacent targets is relatively close, due to the sharing of information such as heading and speed between each other, it is convenient to detect the abnormality of the other party in time, so as to take corresponding measures to effectively avoid the collision of the two targets.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1 A marine target abnormality warning system based on visual situation display is shown, comprising a fixed base station installed on the coast, a command center connected to the fixed base station signal, a mobile base station installed on the target ship, and a cruise rescue team, wherein the mobile base station is connected to the fixed base station signal, and the cruise rescue team is connected to the command center signal; The command center signal is connected with a visualization display module, an early warning module, an early warning response module, a normal behavior model library and an abnormal rating module. The target ship is also equipped with a data acquisition module, a data processing module and a data analysis module. The relevant information collected by the data acquisition module is processed by the data processing module, and then analyzed by the data analysis module. After the analysis, the analysis results can be fed back to the command center. The command center can compare the analysis results with the data in the normal behavior model library to determine whether the target ship is abnormal. When an abnormality occurs, the abnormality can be rated according to the magnitude of the data difference. The command center can give priority to early warning responses to more urgent abnormal ships based on the ratings; The normal behavior model library can collect and record the normal behavior data of ship navigation, such as navigation speed, navigation trajectory, heading direction, navigation area, ship safe navigation data range, etc. When there is a navigation situation that does not conform to the normal behavior model library, it is judged as abnormal navigation. At this time, the early warning module can alarm, and the command center can send the early warning situation to the corresponding target ship through the communication between the fixed base station and the mobile base station, so as to facilitate the timely adjustment of the navigation plan and take corresponding measures to the abnormal parts, effectively avoiding the safety hazards caused by abnormal situations.

[0020] like Figure 2 By comparing with the normal behavior model library, when abnormal deviation occurs, the command center can plan a navigation plan for returning to the original route and feedback it to the target ship after the warning. At this time, the target ship will perform self-correction according to the plan. If the target ship is difficult to return to the route by itself, the control center can control the cruise rescue team near the target ship through the early warning response module to approach the target ship, thereby guiding it to return and achieve rapid rescue. Compared with the existing technology, it greatly improves the speed of abnormal ships returning to normal routes and reduces the risk of loss of contact.

[0021] like Figure 3 , multiple target ships on the sea are connected by signal with each other, and multiple target ships form a self-service information chain, each target ship is equipped with multiple self-diffusion chains, multiple self-diffusion chains are equipped with signal transmitters, the signal transmitters are connected with other target ships and fixed base stations by signal, the same target ship is connected with at least two other target ships by signal, and the two target ships connected by signal meet at least one of the following conditions: the distance between two adjacent ships is not more than 50km, and the distance between the two ships is the smallest compared with other ships, so that in the same sea area, multiple target ships are cross-correlated with each other in information, when one of them loses contact or deviates, its range can be quickly locked according to the position of the target ship associated with it, when the loss of contact abnormality occurs, the difficulty and scope of search and rescue can be reduced in the sea area without reference objects, and the safety hazards of abnormal ships after the abnormality are reduced.

[0022] There are multiple fixed base stations, and one is set up at a certain distance along the coastline. The mobile base station on the target ship is connected to the signal of the nearest fixed base station, so that target ships in different areas can establish signal connections with different fixed base stations, thereby making it less likely for the target ship to lose contact or have difficulty in establishing contact with the fixed base station due to the fixed base station being too far away.

[0023] In the above-mentioned marine target abnormality warning system based on visual situation display, multiple targets sailing at sea can share information with each other, thereby forming a self-service information chain. On the one hand, when the distance between adjacent targets is relatively close, due to the sharing of information such as heading and speed between each other, it is convenient to detect the abnormality of the other party in time, so as to take corresponding measures to effectively avoid the collision of the two targets. On the other hand, when the distance between adjacent targets is relatively far, when deviation or loss of contact occurs, the location range can be narrowed through adjacent targets, thereby reducing the difficulty and time of search and rescue, and improving the safety of the lost target.

[0024] The second implementation method: This embodiment is based on the first embodiment, and a self-diffusion chain is added, and the rest of the parts are consistent with the first embodiment.

[0025] Figure 4 As shown, a mounting plate 1 is fixedly connected to the tail of the target ship, and multiple self-diffusion chains are fixedly connected to the mounting plate 1. The self-diffusion chain includes a sealing pipe head 3 fixedly connected to the mounting plate 1, a double-layer rope 2 fixedly connected to the end of the sealing pipe head 3, and a collection chain fixedly connected to the end of the double-layer rope 2 away from the sealing pipe head 3. The collection chain includes an extended chain body 41, multiple floats 42 respectively fixedly connected to the extended chain body 41, and multiple tail deformation balls 43 respectively fixedly connected to multiple ends of the extended chain body 41. The data acquisition module includes but is not limited to radar, flow rate sensor, water pressure sensor, and locator. The radar, flow rate sensor, water pressure sensor, locator, etc. are respectively provided in duplicate, one is installed on the hull of the target ship, and the other is installed on the self-diffusion chain. When driving normally, they are directly exposed to the sea surface, which is convenient for directly sensing and detecting the sea surface conditions, and for timely detecting abnormal sea surface fluctuations, foreign objects, etc., so as to timely adjust the navigation plan to avoid dangerous factors and improve the safety and stability of navigation.

[0026] like Figure 5-6 The sealed pipe head 3 includes a fixed pipe segment 31 fixedly connected to the mounting plate 1 and a movable pipe segment 32 threadedly connected to the fixed pipe segment 31. The double-layer rope 2 includes an outer rope layer 21 fixedly connected to the movable pipe segment 32 and an extension rope 22 fixedly connected to the outer rope layer 21 away from the inner wall of the fixed pipe segment 31. One end of the extension rope 22 away from the vertical inner wall of the outer rope layer 21 is fixedly connected to the fixed pipe segment 31.

[0027] like Figure 7-8The extended chain body 41 includes an outer hollow rope sleeve 411 and an inner liquid-conducting rope core 412 located inside the outer hollow rope sleeve 411. The outer hollow rope sleeve 411 is fixedly connected to the outer rope layer 21, and the inner liquid-conducting rope core 412 is fixedly penetrated through the outer rope layer 21 and twisted with the extension rope 22. The outer and inner rope layers 21 of the outer rope layer 21 are in a relaxed state, and the length of the extension rope 22 after straightening is not less than 20-50 times the length of the outer rope layer 21. When loss of connection or yaw occurs, the crew can manually separate the fixed pipe segment 31 and the movable pipe segment 32 to make The outer rope layer 21 is separated from the sealing pipe head 3, thereby driving the extension chain body 41, the float 42 and the tail deformation ball 43 to expand outward as a whole, thereby effectively expanding their distribution range. On the one hand, it expands the monitoring range of the surrounding sea surface conditions, and thus detects abnormalities more promptly, so that lost or distorted ships can detect and respond to unexpected situations in time. On the other hand, when a loss of connection occurs, it can expand the range and location of the distress signal to the outside, thereby increasing the probability of re-establishing contact with nearby ships or fixed base stations and improving the probability of being rescued.

[0028] The outer hollow rope sleeve 411 is made of ultra-high molecular weight polyethylene material, which is water-resistant and corrosion-resistant. It is not easily corroded and damaged by seawater when immersed in seawater. The inner liquid-conducting rope core 412 is made of highly water-absorbent material, and the extension rope 22 is a wire body made of a water-absorbent material and a wire body made of ultra-high molecular weight polyethylene material twisted together.

[0029] The outer hollow rope loop 411 is fixedly connected to the end of the tail deformation ball 43 with a one-way valve 413. The tail deformation ball 43 includes an outer low expansion ball 431 fixedly connected to the outer end of the one-way valve 413 and an inner high expansion ball 432 located inside the outer low expansion ball 431. The outer low expansion ball 431 and the inner high expansion ball 432 are both made of highly elastic and corrosion-resistant materials. The inner high expansion ball 432 is in a folded and compressed state, and the inner high expansion ball 432 is filled with effervescent particles. The outer low expansion ball 431 is filled with saturated inflation gas. The signal transmitter 51 is fixedly connected to the inner wall of the outer low expansion ball 431 opposite to the one-way valve 413, and the outer cover of the signal transmitter 51 is provided with The water-proof shield 52 and the one-way valve 413 are fixedly connected to the inner high expansion ball 432. Through the setting of the one-way valve 413, the gas generated by the effervescent particles inside the inner high expansion ball 432 in contact with water is difficult to overflow. At the same time, it does not affect the external seawater from entering the tail deformation ball 43 along the extension rope 22 and the inner liquid-conducting rope core 412, so that the inner high expansion ball 432 can stably grow larger, thereby significantly increasing its buoyancy, and it is not easy for it to be completely submerged in the sea water. It is effectively ensured that it floats on the sea surface, so that it can stably send signals to the outside, increase the possibility of it contacting other ships and fixed base stations again, and improve the probability of being rescued.

[0030] It is worth noting that the outer low expansion ball 431 is a transparent structure, and a plurality of small and dense reflective sheets are adhered to the surface of the inner high expansion ball 432. In the event of loss of connection, after the tail deformation ball 43 is expanded, the plurality of small and dense reflective sheets are all facing outward. At this time, when encountering light, the movement of the water surface can produce an obvious dynamic reflective effect, making it more likely to be discovered by the cruise search and rescue team or nearby ships, further increasing the probability of self-rescue.

[0031] In summary, multiple targets sailing at sea can share information with each other, thus forming a self-service information chain. On the one hand, when the distance between adjacent targets is relatively close, due to the sharing of information such as heading and speed between each other, it is convenient to detect the abnormality of the other party in time, so as to take corresponding measures to effectively avoid the collision of the two targets. On the other hand, when the distance between adjacent targets is relatively far, when deviation or loss of contact occurs, the position range can be narrowed through adjacent targets, the difficulty and time of search and rescue can be reduced, and the safety of the lost target can be improved; in addition, with the setting of the self-diffusion chain, under normal circumstances, the sea surface conditions can be monitored in real time, which is convenient for timely adjustment of the navigation plan and effectively ensuring safe and stable navigation. In the event of loss of contact, the distribution range can be directly increased, and signals can be sent to the outside world in multiple points, so as to facilitate timely contact with fixed base stations or nearby target ships, and effectively realize self-rescue in abnormal situations.

[0032] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
