Description

Technical Field

[0001] The present invention belongs to the field of accident early warning, and relates to a method and system for early warning and prediction of ship impact on the revetment. Background Art

[0002] The prediction of ship impact on the revetment accident is to accurately predict the impact point, time, and intensity, that is, the three elements of impact, before the ship impacts the revetment, so as to greatly avoid casualties caused by the occurrence of ship impact on the revetment under unknown circumstances. At present, the trend of ship large-scale development is obvious. Ship impacts on the revetment caused by sudden changes in water conditions and ship failures occur from time to time. Since the ship is sailing on the water, the perceived ship speed is slow, there is a certain lag in ship control and course change, and the ship has a large load, resulting in the ship developing rapidly before impacting the revetment and being difficult to attract the attention of people on the shore before impact. At the same time, ship impact is likely to cause the collapse of the revetment, seriously endangering people's lives and property safety. At present, the revetment lacks methods and systems for active monitoring and prediction of ship impact, and the research and development of relevant methods and systems have become an urgent objective need. Summary of the Invention

[0003] The purpose of the present invention is to provide a method and system suitable for predicting ship impact on the revetment to meet the protection needs of people's lives and property safety in view of the deficiencies of the prior art.

[0018] Optionally, according to the warning distance requirements of the alarm devices for the revetment, distributed externally field alarm front-ends are arranged at intervals along the revetment parallel to the shoreline to cover the warning area of the revetment. Generally, they are set in the areas where people are active on the revetment; the sound of the high-volume speakers of the distributed externally field alarm front-ends arranged at intervals covers a revetment area within the range of 50m 2 to 1000m 2 The adjacent high-volume speakers have an overlapping sound coverage of 5% to 20%.

[0037] The present invention discloses a method and system for predicting ship impact on a revetment. A plurality of sets of ship impact revetment field perception front - ends and ship impact prediction distributed field alarm front - ends are arranged at a certain distance along the front of the revetment where ship impact is predicted. In the anti - collision warning system, a water virtual warning area of multiple groups of revetment front - line is delimited on the waterside of the revetment front. When the ship AIS and image recognition trajectory deviate from the waterway and the ship has invaded the water virtual warning area, and the actual route of the ship or the predicted trajectory within a certain future time intersects with the revetment front - line, the backend anti - collision warning system forms an impact record and simultaneously issues a ship impact on the revetment alarm message and evacuation information. The alarm content includes information such as the name and model of the impact ship, the impact point, the impact intensity, the impact countdown, etc. On the revetment section where the impact occurs, the impact information and evacuation information are sent through devices such as audible and visual alarms, variable message electronic signs, and mobile phone APPs.

[0038] According to the monitoring distance requirement of the perception device for the water area, the field perception front - ends are arranged at intervals along the revetment front parallel to the shoreline to cover the ship impact perception area. The scanning range of the 3D lidar and the video monitoring range of the field perception front - ends arranged at intervals cover the water area 20m to 1000m in front of the revetment. The monitoring ranges of the field perception front - ends arranged at intervals have an overlapping coverage of 5% - 20%. The AIS signal receiving device, 3D lidar, video monitoring camera, and the three - proof chassis containing the front - end computer and network equipment of each set of field perception front - ends are installed on the monitoring pole or other suitable attachments at a certain height. The monitoring distance is 20m to 1000m, the interval distance is taken as 30m to 200m, and the installation height of the 3D lidar and the video monitoring camera is taken as 5m to 20m from the ground.

[0039] For the described method of distributing and arranging the front-end of the ship impact prediction distributed outfield alarm, according to the warning distance requirements of the alarm equipment for the revetment, distributed outfield alarm front-ends are arranged at intervals along the revetment parallel to the shoreline to cover the revetment warning area as required. The sound of the high-power speakers of the distributed outfield alarm front-ends arranged at intervals can cover a revetment area within a range of 50m 2 to 1000m 2 The overlapping coverage of the sound of the high-power speakers arranged at intervals is 5% - 20%. The visual coverage of the strobe lights and warning light strips of each set of distributed outfield alarm front-ends can cover a revetment area within a range of 50m 2 to 500m 2 The overlapping coverage of the visual coverage of the strobe lights and warning light strips arranged at intervals is 5% - 20%. Each set of variable message electronic displays is arranged at the entrance and exit of the revetment.

[0040] The outfield perception front-end consists of an AIS system, a three-dimensional lidar ranging system, a video surveillance system, a ship impact model calculation system, and a network transmission system. When the AIS system detects that the AIS track of a ship intrudes into the virtual waterborne warning area in front of the revetment set within the anti-collision warning system, the video surveillance system starts ship image recognition, uses motion object detection based on the background to model the ship area captured in the image, judges the difference between the ship's motion trend and the ship's AIS track using the model, synchronously starts the three-dimensional lidar ranging system to conduct three-dimensional lidar point cloud scanning of the target ship, compares the image model and the point cloud model, strips and obtains the monitoring target model, further establishes a ship freeboard model, a speed model, a course model, a distance-to-shore model, and a local coordinate model, and submits the ship name, ship type, real-time ship speed, real-time ship course, ship freeboard data, and target local coordinates to the back-end of the anti-collision warning system in real time through the network transmission system.

[0041] The back-end of the anti-collision warning system consists of a geographic information system, a virtual waterborne warning area setting system, a real-time analysis system for ship impact models, an emergency information recording and publishing system, and a monitoring equipment management system. When the back-end of the system receives data from the outfield perception front-end of ship impact on the revetment, it calculates the ship impact point, impact intensity, and impact countdown through the geographic information system and the real-time analysis system for ship impact models, and sends signals to the distributed outfield alarm front-end of ship impact prediction according to the setting rules of the virtual waterborne warning area setting system.

[0042] The described geographic information system includes a two-dimensional and three-dimensional electronic waterway map database, a three-dimensional real-scene model database, a revetment BIM model, a dynamic ship AIS track module, a dynamic ship radar module, and a three-dimensional ship model library.

[0043] The virtual waterborne warning area setting system is characterized by including the planning of the virtual waterborne warning area and the setting of warning content.

[0044] Ship impact model real-time analysis system, including revetment structure grid, two-dimensional and three-dimensional revetment impact models, and historical results of ship impact simulation calculations.

[0045] The emergency information recording and publishing system described above includes voice announcements, light warnings, electronic screen warnings, evacuation information, SMS notifications, and synchronization of other system information according to the system requirements set for the virtual water warning area.

[0046] The monitoring equipment management system described above includes equipment data collection, basic parameter setting of the equipment, and equipment operation status management.

[0047] The equipment data collection of the monitoring equipment management system collects AIS data, three-dimensional point cloud ranging data, video surveillance data, and calculation results of the front-end system, including the name of the impacting ship, ship type, freeboard height, speed, course, distance, local coordinates, and time.

[0048] The ship impact prediction distributed outfield alarm front-end system is composed of a high-volume horn, a strobe light, a warning light strip, a variable message electronic screen, and a mobile phone APP.

[0049] The following further describes the present invention with reference to the embodiments shown in the accompanying drawings.

[0050] As Figure 1As shown in the figure, the ship impact revetment warning method of the present invention has the following specific prediction working steps: When the embedded AIS signal receiver 10 in the outfield perception front-end system 03 detects that the ship AIS trajectory invades the virtual warning area 13 on the water in front of the revetment set in the ship impact revetment prediction system 15, the video camera 09 monitoring system starts ship image recognition. Using background-based moving object detection, the ship area captured in the image is modeled, and the difference between the ship movement trend and the ship AIS trajectory is judged using the model. At the same time, the 3D lidar 08 ranging system is started to perform 3D lidar point cloud scanning on the target ship. By comparing the trajectory model, the image model and the point cloud model, a more accurate monitoring target model is obtained by stripping. Further, a freeboard model, a speed model, a course model, a distance-to-shore model and a local coordinate model of the invading ship 07 are established, and the ship name, ship type, real-time ship speed, real-time ship course, ship freeboard data, and local coordinates of the invading ship are submitted to the ship impact revetment prediction system 15 in real time through the network transmission device 11. After the system receives the data from the ship impact revetment outfield perception front-end system 03, the ship impact point, impact intensity, and impact countdown are calculated through the geographic information system 23 and the ship impact real-time analysis system 20, and signals are sent to the distributed outfield alarm front-end according to the setting rules of the virtual warning area setting system 19 on the water. The integrated variable message electronic display and the embedded high-volume horn 05 play voice and text alarm information, including impact countdown, impact location, impact intensity, and evacuation guidance information. The flashlights 06 on the water side in front of the revetment flash synchronously to warn the crew, and the warning light belts 04 at the revetment entrance and exit flash synchronously. The ship impact warning information is simultaneously synchronized to the mobile APP and text messages.

Among them, the outfield perception front-end system 03 is as Figure 3 shown, and is composed of a 3D lidar 08, 7 video surveillance cameras 09, an embedded AIS signal receiver 10, a network transmission device 11, and a front-end computer 12.

[0053] The distributed outfield alarm front-end system is as Figure 3 shown, and is composed of a variable message electronic display and an embedded high-volume horn 05, a warning light belt 04, and a flashlight 06. Multiple sets of equipment are arranged in sequence on the water side in front of the revetment as Figure 4 shown.

[0054] As Figure 3As shown in the figure, in order to ensure that the outfield perception front-end system 03 can accurately capture the ship 07 impact behavior, according to the actual needs of water area monitoring, the outfield perception devices are arranged at intervals of 100 m along the front of the revetment 01 parallel to the shoreline to cover the ship 07 impact prediction area with the outfield perception front-end 03. The outfield perception front-end three-dimensional lidar 08 scanning range is arranged at intervals of 100 m, and the video camera 09 monitoring range covers the water area 14 in front of the revetment from 20 m to 1000 m. The monitoring ranges of the outfield perception front-ends 03 arranged at intervals overlap by 5% - 20%. Each set of outfield perception front-end embedded AIS signal receiving device 10, three-dimensional lidar 08, and video surveillance camera 09, including the three-proof chassis of the front-end computer 12 and network device 11, are installed on the monitoring pole or other suitable attachments at a certain height. The monitoring distance is from 20 m to 1000 m, the interval distance is taken from 30 m to 200 m, and the installation height of the three-dimensional lidar 08 and video surveillance camera 09 is taken from 5 m to 20 m above the ground.

[0055] As Figure 4 shown in the figure, in order to ensure that the distributed outfield alarm front-end system can accurately transmit the ship impact warning signal, a flash lamp 06 is set on the water surface of the front of the revetment to warn the ship driver of the possible impact position. An integrated variable message electronic screen and an embedded high-volume horn 05 are arranged at the exit passage of the wharf front for the release of impact warning information and evacuation guidance text and voice information. At the entrance and exit passage of the revetment, warning light belts are arranged to guide the personnel to evacuate.

[0056] As Figure 5 shown in the figure, in order to ensure that multiple sets of outfield perception front-end systems 03 and distributed outfield alarm front-end systems can work properly, it is necessary to cooperate with the ship impact on the revetment prediction system 15 for unified management and maintenance. The ship impact on the revetment prediction system mainly includes a geographic information system 23, a water virtual warning area setting system 19, a ship impact real-time analysis system 20, an emergency information recording and release system 16, and a monitoring device management system 17.

When a ship enters this area, the ship impact on the revetment prediction system can predict the trajectory and impact of the intruding ship 07.
