"Tianzhou II" successfully docked! Three minutes to understand the shocking black technology on "Tianzhou II"! Headlines

When tianzhou-2 docked with the space station , Using a black technology that refreshes the world's cognition , By means of manual remote control, the tianzhou-2 spacecraft has been docked with the national space station . Astronauts operate the cargo spacecraft to dock with the space station through remote control , Compared with the past, it can only be fully automatic docking , Or they can only rely on the direct operation of the pilots inside the spacecraft , It can already be regarded as black technology , Because the real purpose of this remote operation is not to operate the cargo spacecraft to dock with the space station , Its real purpose , In fact, it paves the way for the extravehicular humanoid robot .

Hightopo build “ Tianzhou I ” Cargo ship digital twin management system .HT Three dimensional simulation technology can show the main body of the spacecraft in many dimensions 、 Carrier information 、 flight test 、 Technology experiments 、 Operation process and other key management objects , Support the situation visualization monitoring in full range space . Smart space is based on big data 、 Cloud computing 、 Application platform of artificial intelligence technology , It can extract effective information from massive data more quickly , Provide strong support for intelligent decision making .

// Simulate the operation of a spaceship

The earth in the form of three-dimensional, supplemented by matching the geographical environment map for three-dimensional virtual simulation display , And display the distribution of developed dense areas by highlighting scattered points . The interface consists of 3D Lightweight scene matching 2D Data panel and animation driven , The picture shows the complete interface ：

choose 3D The visual monitoring platform can present a three-dimensional and comprehensive real-time picture of spacecraft operation , It also supports real-time acquisition and telemetry of docking spacecraft sensors 、 Remote signaling information , Auxiliary monitoring personnel through the data of the spacecraft operation situation 、 A healthy state 、 Early warning information, etc .

2022 year 1 month 6 Japan , China's first space station manipulator , Operate the large on orbit vehicle, namely tianzhou-2, to conduct the transposition experiment , And achieved complete success .

// All round display of data

For the complicated space data , Want super precision 、 high efficiency 、 Large scale processing and analysis of data , It takes time 、 Space 、 Classification and other multi-source data analysis , And then present the propellant of the spacecraft in real time 、 Carry 、 flight test 、 Technical experiments and other status information , And according to the warning prompt to quickly locate the problem .

At the same time, the interface can be added with a time axis running history , Carry out historical backtracking and simulation exercises , Click the time node to play the animation of the corresponding process .

Tianzhou （ Including tianzhou-1 、 Tianzhou-2 ） The cargo ship consists of a large-diameter cargo cabin and a small-diameter propulsion cabin . Cargo hold is used for loading cargo , The propulsion module provides power and electricity for the entire spacecraft . There are three solar panels on each side of the propulsion module ,3D The visual simulation demonstration is as follows ：

// Autonomous guidance Visualization

Tianzhou-1 needs human assistance to guide the spacecraft to a certain distance from tiangong-2 in the long distance , Then the spacecraft independently completes the close rendezvous and docking .

Before and after every orbit change , The ground TT & C station must first accurately measure the orbit of spacecraft and space laboratory , After taking control of their exact location now and in the future , Give orders to the spaceship . Such a link is a link , At every step, the spaceship must be strictly controlled within the predetermined range , Finally, we can ensure the normal implementation of spacecraft autonomous guidance .

// Autonomous docking Visualization

according to the understanding of , Rendezvous and docking is one of the three basic technologies for manned space activities , It is the assembly of space station and space transportation system 、 supply 、 maintenance 、 Recycling 、 Prerequisites for on orbit services such as astronaut exchange and rescue . But the motion of the spacecraft is unpredictable , Its flight speed can reach 8 Km/s, In order to ensure the smooth docking of the spacecraft , The ground monitoring personnel must obtain the flight situation from the data at the first time , And the raw data that the spacecraft sends back per second is 8G As much as , It's just a manual solution , Efficiency will be greatly reduced .

HT Built 3D Visual application layer , By virtual spaceship , It opens the bridge between abstract model and data presentation , Endow with “ class / object “” Formally expressed “ Device model / Examples of equipment ” The effect of simulation visualization .

The spacecraft's rendezvous and docking mainly depends on the ground measurement and control , The orbit parameter injection command generated by the monitoring personnel on the ground , For example, when the engine of the spaceship is turned on, it will be a long time , Monitoring personnel can still analyze, judge and make decisions based on the real-time data presented on the large data visualization screen .

// Refuelling Visualization

Switch to Visualization , Through transparency, models other than key equipment , Visually display the distribution of energy equipment , The monitoring personnel can directly observe the fuel supply status in the cabin , Present information about spaceships and propellant reserves .

Real time display of various monitoring data received through 3D visualization platform 、 Detect the whole process and other necessary state information . In addition to the traditional manual modeling ,HT Support for BIM Model display function , There will be structures 、 Engineering and other information BIM The model is lightweight , Make sure the scene is Web Load and run efficiently and smoothly in . Use the event mechanism to update the interface locally , avoid FPS The way of playing , Too many meaningless interface refreshes , Avoid desktop jams and hot mobile phones .

HT The application of visualization technology realizes data sharing , Gradually realize the digitalization of industry 、 greening 、 Intelligent . Using lightweight 3D Modeling Technology , adopt HT Achieve interactive Web Three dimensional scene , Zoomable 、 translation 、 rotate , Each device in the scene can respond to interactive events .

HT 3D visualization technology adopts B/S framework , User access PC 、 PAD Or smart phones , As long as you open the browser, you can access the 3D visualization system anytime and anywhere , Realize remote monitoring and control . adopt B/S Architecture combined with model lightweight , HT First of all, 3D visualization technology reduces the user's pressure on purchasing high-performance hardware to a certain extent , Secondly, it breaks the limitation of the previous management scenario that users manage in the monitoring room .

2021 For the whole line of manned spaceflight project, the year 2010 is full of harvest 、 A fruitful year ,5 The missions were fought in a row , The construction of the space station has achieved phased results , For the first time, Chinese people settled in their own ‘ Space home ’, History is constantly breaking new records in the hands of hard workers .
