A Long March 2F rocket carrying the Shenzhou XII manned spacecraft blasted off from the Jiuquan Satellite Launch Center at 9:22 a.m. Beijing time on June 17, 2021. Astronauts Nie Haisheng, Liu Boming and Tang Hongbo entered the core module at 18:28, marking the first time that Chinese people entered their own space station.

preface

As a great cause of human exploration into the vast space, space flight produces a large amount of real-time data during the development and operation of each product, through which monitors need to know the coordinate, relative position and situation of the product. Intelligent spaceflight is an application platform based on big data, cloud computing and artificial intelligence technologies. Its emergence can extract effective and accurate information from massive data more quickly, providing strong support for intelligent decision-making.

Today, Hightopo’s product HT will be used to build the digital twin management system of “Tianzhou-1” cargo spacecraft. HT 3D simulation technology can visually display the operation state of key management objects such as the main operation of the spacecraft, carrier information, flight test, technical experiment and operation history in multiple dimensions, and support the visualized monitoring of the situation in the whole range of space.

Animation display

The earth is presented in a three-dimensional form supplemented by matching the map of geographical environment to carry out three-dimensional virtual simulation and display, and the position of each country is distinguished by the color of the highlighted part. At the same time, HT has the function of transforming BIM model to HT primitives, which can do lightweight processing for BIM files to ensure the efficient and smooth loading and running of scenes in the Web.

Simulated spacecraft operation

The interface is constructed by 3D lightweight scene, 2D data panel and animation driver. The complete interface is shown in the figure below:

The 3D visualization monitoring platform can present a three-dimensional and comprehensive real-time picture of the operation of the spacecraft, and support the real-time acquisition of data from the docking sensor of the spacecraft, and assist the monitoring personnel to quickly judge the operation status, health status, warning and warning information of the spacecraft through the data. To ensure that the spacecraft running trajectory is always in a stable state, optimize the traditional operation process.

Comprehensive display of data

For complex space data confused, want to super precision, high efficiency, wide range of process analysis data, the need to sort through time and space, such as multi-source data analysis, and real-time rendering of propellant spacecraft, carrier and flight test status information and technical experiments, and according to the early warning alarm prompt rapid positioning problem.



At the same time, timeline type operation history can be added to the interface for historical review and simulation exercise. Click the time node to play the animation of the corresponding process separately.

Windsurfboard expansion visualization

The Tianzhou cargo spacecraft consists of a large diameter cargo compartment and a small diameter propellant compartment. The cargo bay is used to hold the cargo, while the propellant bay provides the power and electricity for the entire spacecraft. There are three solar panels on each side of the propellant module. The 3D visualization control is demonstrated as follows:

Autonomous guidance visualization

In the long distance section, Tianzhou-1 will need manual assistance to guide the spacecraft to a certain position from Tiangong 2, and then the spacecraft will autonomously complete the close docking.



Before and after each orbit change, the ground observation and control station must first accurately measure the orbit of the spacecraft and the space laboratory, control their present and future accurate positions, and then give orders to the spacecraft. In this way, each step must strictly control the spacecraft within the predetermined range, so as to ensure the normal implementation of the autonomous guidance of the spacecraft.

Autonomous docking visualization

It is understood that space rendezvous and docking is one of the three basic technologies for manned spaceflight activities, and is a prerequisite for in-orbit services such as assembly, supply, maintenance, recovery, astronaut exchange and rescue of the space station and space transportation system. However, the movement process of the spacecraft is unpredictable, and its flight speed can reach 8 Km/s. In order to ensure the smooth progress of the autonomous docking of the spacecraft, the ground monitoring personnel must obtain the flight reality in the first time from the data. However, the original data sent back by the spacecraft is as much as 8 gigabytes per second, and the efficiency will be greatly reduced simply by relying on manual solution.

Data visualization can simplify and refine the messy intelligence data, and analyze and judge in real time by combining the professional data model and analysis algorithm in the aerospace field. It helps to obtain higher value of data, helps to enhance the decision-making and judgment ability of monitors, and improves the efficiency of data analysis to a certain extent.

The completion of spacecraft rendezvous and docking mainly relies on ground measurement and control. Orbit parameter injection instructions generated by monitors on the ground, such as spacecraft engine starting and long point position, can still be analyzed, judged and made decisions according to real-time data presented on the data visualization screen.

Refueling visualization

Switching to a visual effect, the monitor can directly observe the fuel replenishment status in the cabin, and present the information of the spacecraft and propellant reserves.

Tupu software aerospace series

Not long ago, the “Zhu Rong” rover has safely left the landing platform, reached the surface of Mars, began to patrol and explore. “Zhurong” is China’s first self-designed rover, which is of great significance to the development of China’s space industry. Here is Hightopo’s rover detection scenario using HT.

The received monitoring data, the whole process of detection and other necessary state information are presented in real time through the 3D visualization platform. Systematic, real-time and accurate are the main performance characteristics of the 3D Mars rover exploration system. Web 3D has unlimited imagination space, super rich data presentation way, brand-new visualization effect.

The application of HT visualization technology realizes data sharing, and gradually realizes the digitization, greening and intelligence of the industry. Whether shuttle run, rocket launch, the solar system, or the Mars rovers, which can be covered by the 3 d visual interface for the state, the relative position, quality, resource content such as the real-time control of understanding, ability more robust in space exploration, state of the planet can even through the system for real-time monitoring, On-line monitoring of astronauts’ work sites and work conditions.



Nowadays, the application scope of intelligent space has already extended beyond the earth to the universe. Hightopo uses 3D data visualization to carry out virtual simulation of spacecraft and space. At the same time, a series of rendering effects such as halo are added to reproduce the real environment of space cleverly.

For space industry, data is not only the basis of space theory, but also the cornerstone of space practice. A series of operations of intelligent space can be realized through the lightweight 3D visualization scene of Hightopo, which moves the whole universe into PC, Paid and mobile terminal for cross-platform display. The scene supports conventional rotation, translation and perspective scaling.

conclusion

Carve a new height for China in the vastness of space. From the ancient myth of Chang ‘e’s flight to the moon, to Quyuan’s “Heavenly Questions”, the ancient Chinese people’s curiosity and questioning about the mysterious space have become a reality in the exploration of Chinese space workers. Tu Pu is willing to assist aerospace researchers to contribute to the space industry, and jointly write a new chapter in the space industry.

Hightopo data visualization also deeply integrates manufacturing, wind power, energy, urban parks and other industries to boost intelligent manufacturing and digital transformation, so that industrial operation and maintenance can be traced, equipment operation can be supervised, enabling everything to exchange information, resource sharing and ability collaboration.
