With the rapid development of civil aviation, the field of civil aviation has gradually accumulated a large amount of aviation data. As one type of typical data, civil aviation flight trajectory data includes many information such as space-time position, speed, altitude and heading, which contains the behavior characteristics and space-time characteristics of the aircraft during flight. These characteristics are important for the safe operation and efficient management of civil aviation. significance. Therefore, how to use data processing technology and visualization technology to explore and analyze civil aviation flight trajectory data, and mine the potential information behind it, so as to guide civil aviation management decision-making and promote the development of civil aviation, is an important research topic today.
Through the Tupu software visualization system, the aircraft shape, cabin management, cabin equipment, engine, and cockpit are digitally twinned in a science fiction style, and various data are sorted out through the Internet, cloud computing, big data analysis, artificial intelligence and other technologies. After integration and analysis, it will be displayed on the hightopo visual large screen to establish a scenario-based, intelligent, and humanized smart aircraft comprehensive management and control platform, providing managers with diversified, multi-angle, and multi-data management and decision-making basis. Through the practice of civil aviation metaverse, build a green, intelligent and safe intelligent civil aviation management system.
model selection
The 3D scene of the Tupu visualization system uses three different types of aircraft as examples to display the appearance parameters. Airbus A380 (Airbus A380) is a super-large long-range wide-body airliner with four engines developed and produced by the European Airbus Company. The Boeing 787 (Boeing 787) is the first ultra-long-range mid-size airliner in aviation history. Boeing 727 (Boeing 727) is a short- and medium-range civil aviation aircraft developed and produced by Boeing Company of the United States.
Using technologies such as virtual simulation and digital twins, combined with Tupu software's self-developed engine HT for Web, it renders 2D and 3D seamlessly integrated flight scenes, and simulates the aerodynamic layout and wing geometry of Airbus A380, Boeing 787, and Boeing 727 parameters etc.
After selecting the model, the overall appearance of the currently selected model will be displayed in the form of roaming animation. Clicking on the small gradient triangle next to a different model will pop up a brief introduction of the current airliner to learn about the history, engine, engine, etc. of the airliner. The real-time flight data is connected to the large visualized screen, seamlessly linking the flight management systems of various flying aircraft, real-time monitoring of aircraft equipment data and passenger status, etc., and realizing real-time data sharing between the tower and the flying aircraft. Pre-warning and post-event review can effectively reduce the occurrence of various aviation accidents.
The new generation of Internet of Things communication based on α-link technology relies on the technical advantages of advanced aviation radio, which improves the transmission efficiency of information and expands the number of connections, and optimizes the limitation that Bluetooth cannot be deployed on a large scale in limited areas. Duplex communication realizes the goal of interconnection of all things, digital empowerment, and precise monitoring.
Tupu software is based on the 3D engine independently developed by WebGL, which can smoothly display the 3D scene and model of the aircraft in the browser, and can also create complex navigation and data visualization. Access to real-time data such as aircraft wingspan, fuel capacity, interference resistance, etc., to achieve refined flight management. Simulate real-time flight images, bringing an immersive look and feel. Through Tupu software's one-stop development tools from view component design, icon design, 2D drawing design to 3D scene design, designers and programmers can realize collaborative development and quickly implement 2D and 3D visualization results of different models.
Airliner parameters
Connect the monitoring data of the airport to the Tupu visualization system, display the wing, fuselage, tail, landing gear, control system and power plant, interference resistance, cargo hold full load rate, etc. of the aircraft type, and assist the control tower and instrument flight command room science for flight management.
Interference resistance
In addition to frictional resistance, differential pressure resistance and induced resistance, "disturbance resistance" is an additional resistance caused by mutual interference of airflow between various parts of the aircraft wing, fuselage, and empennage. Interference drag can be reduced by carefully considering their relative position when designing an aircraft. The real-time resistance data is connected to the Hightopo visualization system. When the resistance is too high, a red triangle warning with an exclamation mark will appear. The ground control tower can contact the crew in time to confirm whether the flight is safe. Records of historical data can also be used for subsequent optimization of aircraft design.
Fuel capacity
There are three categories of aircraft fuel loads, namely the maximum fuel load, the minimum fuel load, and the take-off fuel load. The maximum fuel capacity is the maximum amount of fuel that the aircraft can carry when the aircraft is safe to fly. The minimum fuel load refers to the amount of fuel that the aircraft can fly over the airport at the holding airspeed for 30 minutes after it arrives at the landing airport. Take-off fuel refers to the total amount of fuel carried by the aircraft when performing flight tasks.
In January 2022, the Civil Aviation Administration of China issued the "14th Five-Year Plan" Civil Aviation Green Development Special Plan, clearly proposing to promote the comprehensive green transformation of civil aviation development under the guidance of achieving carbon peak, carbon neutrality and "dual carbon" goals. Combined with sensors, 5G and other technologies, the fuel load data is connected to the 2D panel of the Tupu visualization system, so as to control the fuel consumption at all times and reduce the fuel consumption ratio. Making the actual fuel used as close as possible to the theoretical minimum is the most direct way to reduce civil aviation carbon emissions.
Hold information
Tupu software HT visualization uses rich charts, graphics and design elements to present the data of general cargo, chemicals, overweight items, and fresh items in a more intuitive and understandable form. Connect the real-time data of the cargo compartment with the data of the ground passenger and cargo transportation service area to improve the efficiency of airport loading and unloading.
The loading capacity of the cargo compartment is mainly limited by the weight limit, volume limit, door size limit and floor bearing capacity. For example, the maximum cargo capacity of the Airbus A380 is 66.4 tons. The loading capacity data of the operating aircraft is connected to the visualized 2D panel of Tupu software HT, the current full load rate of the cargo compartment is displayed in percentage, and the data information is clearly and effectively interpreted and communicated by means of graphics. Through the visualization of Tupu software, unmanned monitoring of the cargo compartment and fire warning can also be realized.
cabin management
The "Big Mac" A380 in the sky is the most passenger-carrying civil aviation airliner in the world. Many A380s have gyms, bathrooms, restaurants, bars and other entertainment venues to add fun to passengers' flight. The Tupu software visualization system splits and displays the two-story passenger cabin and luggage compartment of the airliner, visually displays the structure, layout, facilities and equipment in the cabin, and corresponds to its actual position and number one by one, keeping it consistent with the actual scene.
The cabin is divided into first class, business class and economy class according to the spaciousness and comfort of the seats. Connect the ticketing system with the Tupu software visualization system, distinguish the optional seats, non-selectable seats, and VIP seats with colors, and view the remaining seats. For flights with long routes and insufficient passenger sources, the remaining seats can be sold to increase the passenger load rate.
passenger body temperature
At the moment of the epidemic, the heat map is used to display the body temperature test results for epidemic prevention, and the body temperature of passengers with high body temperature is listed separately, and the crew members take targeted countermeasures.
passenger information
The information such as member level, user name, registration number, and available mileage is counted and displayed through Tupu software visualization, which allows flight attendants to adopt more appropriate customer service measures.
flight information

Using Tupu software HT virtual simulation technology, according to the actual aircraft appearance, make a 3D visual simulation interactive model of the aircraft, and strive to display a high-precision model while maintaining complete consistency with the actual aircraft, and grasp flight data through real-time data drive.
Device self-test
Equipment data monitoring is an ongoing supervision, and equipment self-inspection is a reminder in advance. The 2D panel of Tupu civil aviation visualization interface scrolls to display the current safety system status, adding intelligent early warning analysis function, once the system data exceeds the predetermined threshold, the information will be marked red in the list, and maintenance personnel need to check the health status of the equipment in time .
Aircraft System Display
Flight management systems (FMS) automate flight missions. Airborne Health Management System (AHMS) includes aircraft health status monitoring, diagnosis, evaluation, etc. The Atmospheric Inertial Navigation System (ADIRSP) measures the aircraft's position, speed, track, wind direction/speed, attitude, etc. Information system (IS) provides flight information, maintenance information, cabin information and operation information services. The Integrated Modular Platform (IMA) is based on core computing, RTOS and airborne network, and supports system interconnection and data exchange. The main purpose of the communication system (CNS) is to enable the aircraft to maintain two-way voice and signal contact with relevant personnel on the ground such as air traffic control personnel, dispatch, maintenance, etc. during each phase of flight. The display system (CDS) points to the pilot's equipment to provide integrated monitoring and cockpit display control systems for optimum situational awareness.
Combining aircraft system with map visualization and smart airport system for refined flight management.
Tupu Smart Airport relies on the accurate time-space perception of the whole area of the flight area and ubiquitous interconnection to build a "one map of the situation" to realize the visualization of all elements; through the aggregation and fusion of multi-dimensional data and the reasoning and decision-making knowledge map, the whole process can be measured; through the Internet Interoperability and intelligent collaboration enable full-scenario control; seize opportunities for digital transformation.
Aviation activity is an integral sector of transport, which together with rail, road, water and pipeline transport make up the country's transport system. For the green digital transformation of waterway transportation, Hightopo visualization products can also be used to solve the problems of high energy consumption, high cost and heavy pollution of traditional docks and ships.
engine
An aircraft power plant is a device used to generate pull (propeller aircraft) or thrust (jet aircraft) to propel the aircraft forward. In addition to supersonic aircraft and high-subsonic trunk airliners in modern aircraft, propeller aircraft still occupy an important position. Taking the TRENT 900 specification engine as an example, the engine is displayed in an all-round way through four methods: cross-section, air flow, disassembly, and reset. The TRENT 900 turbofan engine is a turbofan engine, which consists of a compressor, a combustion chamber, a high-pressure turbine (to drive the compressor), a low-pressure turbine (to drive the fan) and an exhaust system.
Cutaway showing high pressure turbine blade power, there are 70 high pressure turbine blades on the Trent 900 engine, each producing nearly 600 kWh of power. Through the data binding of the 2D panel visualized by Tupu and the chart, the line chart is used to display the pressure and temperature changes.
The airflow page shows the propulsion efficiency of different types of turbojet engines, inlet airflow values, aerodynamic load, thermal load, centrifugal load and other indices, with red arrows and green arrows to distinguish the incoming and outgoing airflows.
Hightopo shows the internal structure of the engine in the form of equipment disassembly and explosion, showing the names of the various parts of the engine, such as hollow structure fan blades, titanium alloy honeycomb core, honeycomb interlayer, superplastic formed wide chord fan, etc. After the engine is disassembled, every tiny part can be viewed one by one. By accessing the Internet of Things data of components, you can view the current status of each component of the equipment, and realize global monitoring and visualization from macro to micro.
Reset status to view Thrust, Total Pressure Ratio, Inlet Mass Flow, Fan Diameter, Length, Weight, Class Fan, 8 Stage Intermediate Pressure Compressor (IPC), 6 Stage Intermediate Pressure Compressor (HPC), Annular Combustor, Duct than the data. The bypass ratio is the ratio of the air flow of the turbofan engine's outer bypass to the inner passage, and the bypass ratio is closely related to the fuel consumption rate.
Tupu software uses the event mechanism to update the interface locally, avoiding FPS game mode, too many meaningless interface refreshes, and avoiding problems such as desktop freezing and mobile phone overheating.
cockpit
The aircraft control system refers to the entire system from the pilot's control stick (disc) in the cockpit to the horizontal tail, aileron, rudder and other control surfaces, which are used to transmit the pilot's control instructions and change the flight state. Various flight instruments and aircraft control systems are generally installed in the cockpit of an aircraft.
The mode control panel (MCP) is a device that instructs the automatic driving device to perform route, altitude, rate of ascent and descent, and speed. The primary flight display (PFD) includes an attitude indicator, a digital representation of the airspeed and altitude indicators (usually as a tape display), and a vertical speed indicator, among others. Click on the display in the Tupu visualization system to pop up a 2D panel to display the flight information of the flying aircraft.
Engine Indication and Crew Alerting (EICAS/ECAM) will allow the pilot to monitor values N1, N2 and N3, fuel temperature, electrical system etc. The Flight Management System (FMS) is used to enter and check flight plans, speed control, etc. The Multi-Function Display (MFD) provides a viewing area that can be used for flight information integration, engine monitoring, and flight parameter configuration. The Navigation Display (ND) shows current heading information and commands entered into the Flight Management System (FMC).
The application of aviation navigation can provide continuous safe and reliable technical services to aircraft operating in the air. In the 1960s, the INS (inertial navigation system) with autonomous navigation capability was used in the aviation field. It can display the three-dimensional aspects of the aircraft (position, speed), and can also provide important information such as heading attitude.
Compared with other modes of transport, air transport is relatively small in terms of transport volume. The mode of transport for bulk cargo in my country is water transport. With the deep integration of modern information technology, Internet of Things technology, artificial intelligence technology and other advanced technologies with traditional waterway transportation in safety supervision, operation services, ship management, port services, etc., smart transportation has become a reality. Combining Tupu software with GIS maps, according to latitude and longitude information, underwater topography, water flow, wind speed and wind direction and other environmental elements, a three-dimensional dynamic navigation geographical environment integrating point-line-surface is constructed to ensure the safety of shipping.
HT for Web GIS products support the loading of different GIS data such as map tile services or data, 3DTiles format data of aerial oblique photography real scenes, and urban building groups. At the same time, it combines BIM data lightweight, 3D video fusion, and 2D and 3D With technical advantages such as the seamless integration of GIS, the massive POI data, traffic flow data, planning data, and current status data are displayed in a variety of ways in the GIS system.
Today, aircraft are largely designed with an all-digital "glass cockpit" that integrates a GPS receiver into the glass cockpit. The traditional gyroscope has also been replaced by an electronic Heading and Attitude Reference System (AHRS) and an Air Data Computer (ADC), which reduces costs and simplifies maintenance while increasing reliability.
The glass cockpit uses the flight management system to display flight information, and displays different data on demand through the multi-function display. Simplify the pilot's control and navigation of the aircraft, so that the pilot can focus on the most relevant information. Combining big data, cloud computing and other technologies to realize digital and green flight in the general aviation industry.
Since the "13th Five-Year Plan", general aviation and transport aviation have "flyed on both wings", and emerging business forms represented by low-altitude tourism and entertainment flying have flourished, and the application scope and fields of drones have also continued to expand.
Tupu Digital Twin UAV Monitoring System
At the end of the "13th Five-Year Plan", the fuel efficiency level of China's civil aviation increased by nearly 30% compared with 2000, and the cumulative reduction of carbon dioxide emissions was about 360 million tons; the electrification rate of China's airports was nearly 60%, and the proportion of new energy vehicles in the airport reached 16%. The installation rate and utilization rate of replacement equipment exceeded 95%, and the annual power generation of the airport photovoltaic project exceeded 20 million kWh.
With the proposal of carbon peak and carbon neutral goals, not only civil aviation is reducing carbon, but the transportation industry has also made many carbon reduction attempts after the deep integration of digital technology. Focusing on application fields such as the Internet of Vehicles, the Internet of Flying, and smart ports and airlines, it has carried out industry explorations in smart driving, smart airports, and other smart transportation industries.
