New model of maritime supervision | 3D visualization management of smart ships

Preface

Since entering the new century, new-generation information technologies such as cloud computing, big data, and artificial intelligence are developing rapidly. By taking advantage of emerging technologies, all parties in the maritime industry can be linked together through data to simplify complex problems and make hidden costs explicit. The exploration of new modes of maritime supervision has also spawned new combat ideas and combat methods, which have become a powerful driving force for a new round of industrial transformation following mechanization and digitization.

Using the HT products independently developed by the localized Hightopo, a low-code 3D visualization management platform for smart ships is built throughout the whole process. Taking a large surface ship aircraft carrier as a model, it integrates data monitoring of energy power, mission execution, fire prevention and anti-sinking, navigation status, and comprehensive overview. It integrates factors such as situational awareness, risk assessment, and action process control to achieve reliable, controllable, and accurate full-dimensional information perception and application.

Ship Integrated Management Visualization

The overall scene adopts the form of lightweight modeling, and high-precision modeling and restoration of the monitoring area, surrounding environment and appearance required by the ship are carried out.

The navigation aids of modern ships mainly include electronic instruments such as GPS, radar, on-board AIS, ECDIS, etc., which satisfy the driving intensity of the crew to a certain extent, but they are often restricted to dynamic water surface information in the process of use, especially in the When navigating in near-shore shallow waters, the static information of the sea area cannot provide the crew with easily identifiable environmental information in the three-dimensional real-time monitoring.

The combination of selection and geographic information system (Geographic Information System, GIS) can bring a new model for spatial information analysis, which can intuitively and accurately display the ship's latitude and longitude, heading angle, speed, water temperature and depth, wind direction and other information. Integrate the data of intelligent perception equipment to carry out comprehensive visual analysis of many key indicators such as ship mission progress, energy retention, damage management and security. Strengthen the closed-loop management of the ship's own security data, and make macro-control in the face of potential crises, so as to achieve the purpose of all-round planning, layout, analysis and decision-making.

The engine comes with mouse zoom, rotation, panning, zooming in and zooming out operations, and can also perform one-finger rotation, two-finger zooming, and three-finger panning operations on touch-screen devices, so there is no need to worry about different interaction modes across platforms.

Energy Power

As one of the core parts, the ship power system is a vital part of the modern ship equipment, which can ensure the safety of navigation, the power of the ship and the daily needs of the personnel.

The wireframe mode with a sense of technology is selected to make the hangar, power cabin, deck and other parts of the aircraft carrier transparent, so that the crew can view the overall layout structure. The HT virtual simulation technology is used to construct the interaction of equipment such as power room and boiler room. By connecting equipment sensors, dynamic data of ship equipment operation status, comprehensive power data and power distribution information can be obtained in real time. Conform to the development trend of "green ships" and assist the crew to improve the energy efficiency management of ships.

Visualization can not only depict objects seen by the naked eye with images, but also vividly display the information status of the device. Using a wealth of visual graphics components, the key data of the water-cooled pump room, lubricating oil, fuel oil, air conditioning and other systems can be visually displayed, and the number of damaged pipes and the failure time of equipment such as fire fans, near bulletproof warehouses, heat engine rooms, and water pump pipes can be collected simultaneously. , the number of failures, and multiple indicators float on both sides of the 2D panel to create multi-parameter real-time monitoring. By connecting the real-time data sharing between the various systems of the ship, the operation quality and operation level of the power system can be better guaranteed.

The intelligent early warning analysis function is added to understand the health status of the equipment, determine whether the equipment is in a stable state or showing a deterioration trend, and immediately trigger the alarm device when the safety threshold is exceeded, providing a practical basis for fault diagnosis. Improve the efficiency of accident emergency handling and emergency response capabilities, and open up the internal cycle of online monitoring, remote control, and self-regulation, which can not only replace the previous complex manual inspection process, but also meet the complex and changeable conditions of navigation, still provide high-quality power demand.

task execution

Aircraft carriers have established the superiority of maritime hegemony over land powers. Its mission execution is based on aircraft carriers, equipped with a variety of ships, and then forms a maritime combat group, which can perform multiple types of complex combat tasks, and has the ability to maneuver and quickly resist. However, for complex and cumbersome ships to obtain ultra-precise, large-scale, and efficient processing and analysis data, it is necessary to conduct comprehensive research and judgment based on multi-source data such as space, time, and type, and then dynamically present the information of the aircraft carrier's escort formation, Mission map, mission plan and carrier aircraft status information. In the task map, the running history of the task execution can be added according to the requirements, which is convenient for historical backtracking and path tracking. Click the corresponding event node to play the process animation.

Using the powerful rendering function of the HT engine, the traveling effect of the escort formation and the aircraft carrier in different states can be reproduced truly, and the scene can be surveyed in real time without blind spots in a 360° panorama, enhancing the quality and efficiency of combat command and control. Click any ship in the scene to view the demand information, such as the ship model, specifications or operation and maintenance status. Ensure the formation of networked, refined, and integrated combat elements such as combat readiness and duty, strategic early warning, and weapons and equipment.

Fireproof and anti-sink

Fire

Equipped with an automatic fire detection system, it can conduct 24-hour situational awareness, identification, and positioning of the centralized control room, boiler room, dock, living room, hangar and other areas in the ship's cabin. , based on a variety of visual analysis methods such as clustering, grid, activity law, etc., and perform multi-directional parallel analysis according to requirements.

In order to improve the standardization of the emergency defense process, the system can remotely start and stop equipment such as fire doors, stop fans, oil pumps, and fuel quick shut-off valves according to the monitored ship fire state and the concentration of jet fuel combustible gas. When an abnormal condition of early warning alarm is received, the system will automatically release the sound and light alarm signal, start the self-checking and diagnosis function and quickly locate the dangerous area, and efficiently cooperate with the crew to troubleshoot the fault to avoid further expansion of the fire or explosion.

Due to the particularity of ship fires, the 3D visualization fire protection module can also be used to simulate exercises to help the crew feel the real fire scene. HT supports display in combination with WebVR. By adapting VR equipment, users can match head-mounted equipment and handle to realize functions such as grabbing and moving the equipment through the handle, providing an immersive cabin fire experience and strengthening the crew's understanding of the fire rules in the cabin. The cognitive level makes up for the lack of large-scale scene simulation in current fire drills.

Anti-sink

The unsinkability of the ship is an important indicator of the vitality of the ship. It is still sufficient stability and buoyancy after the cabin is damaged and flooded, so as to ensure the inherent ability to float on the water surface.

On the basis of the original ship structure anti-sinking, organically combined with 3D visualization, often the anti-sinking management work can achieve twice the result with half the effort. Matching the intelligent detector, you can check the liquid level of fuel tanks, lubricating oil tanks, jet fuel tanks, fresh water tanks and other tanks online.

According to the ship's trim angle, bow, stern draft, average draft and other shapes under various loading states of the ship, the system is equipped with independent analysis and prediction, abnormal alarm, and intelligent identification functions. When the ship is damaged, according to the anti-sinking measures, the watertight closing device on the boundary of the watertight area and the passage will be remotely closed to support the crew to complete the plugging, support, drainage, balance and positive and negative initial stability, and maintain the ship's safety. Buoyancy and stability.

Sailing Status

Traditional channel information mostly takes two-dimensional static as the main form, the monitoring data is huge and the information screening and analysis is relatively scattered, resulting in great limitations in comprehension and intuition.

In order to avoid the phenomenon of missing or redundant data, HT combines GIS maps and constructs a three-dimensional dynamic navigation geographic environment of point-line-surface-body according to environmental elements such as longitude and latitude information, underwater topography, water flow pattern, wind speed and wind direction. Use the navigation aids in the sight to help determine the position and direction of the ship, and then make up for the lack of relative position sense under poor visibility conditions or to dynamically perceive hydrological information in unfamiliar waters. Accelerate the acquisition of position awareness and external traffic environment, optimize operation efficiency, and meet the comprehensive visualization of navigation environment.

The HT for Web GIS product is intended to solve the realization of the user's GIS project and reduce the user's learning and input cost of GIS. Combined with HT's powerful visualization engine technology, it can realize the overlay display of different map tile data, oblique photography real scenes, 3D refined artificial modeling models, POI and other data. Subvert the development of traditional GIS systems, making development more convenient, data more intuitive, and display more diverse.
