Ask the sky to build a dream!"Chengdu made" escort asked Tian experimental compartment launch successfully

Just now, the Long March 5 Yao Three Lauret Rockets were equipped with the "Tiangong" space station and asked the Tianchang Experimental Class to be launched smoothly at the Hainan Wenchang Launch Center. In this dream -seeking journey, the Tenth Research Institute (hereinafter referred to as the "Ten"), located in Chengdu, contributed a number of equipment and systems.

A new generation of comprehensive test control system

Three highlights to build the "lifeline" of heaven and earth

Ten led land -sea sky base test control communication systems have established a new generation of comprehensive test control system, which is responsible for rail measurement, remote control and data transmission of spacecraft (spacecraft, space station, etc.). The only connection is like the kite kite line of kite, so it is also called the "lifeline" of the spacecraft.

According to reports, the new generation of comprehensive test control system mainly has three characteristics of "intelligence, nationwide, high -reliability".

"Intelligence" is first manifested as a "unified hardware platform, software definition function" like smartphones. Different APPs can achieve different functions. On the same set of test control equipment, a variety of working modes can be run at the same time, and can be compatible with different signal modes, frequency points and goals. The second manifestations are automated operation capabilities, just like the aircraft's autonomous driver instrument. In addition to ensuring safety at the key node, the daily measurement and control movement can be fully operated automatically. In addition, the entire network measurement and control resources have realized the control of cloud architecture, and automatically allocated computing resources according to the task occupation status and equipment health status.

"All", that is, in the new generation of measurement and control systems, from software to hardware, from basic components to whole machines and systems, all have all realized localization. At present, the stability and reliability of domestic operating systems and domestic meta -devices have been greatly improved.

"High reliability", in addition to the aforementioned resource reorganization technology, deep comprehensive technology, and stable and reliable domestic software and hardware, there are health management technology and remote support technology. The health management system integrates traditional faulty trees, expert systems and modern big data technologies, and transforms the "disease -cure" model into "real -time body tests in real time, predicting diseases in the same way".

After recent years of efforts, the coverage of Chinese manned space measurement and control can reach 100%in theory and actual use. In other words, astronauts can enjoy meticulous care for the motherland at any time or place. And both the key arc segments and normal operation can ensure the high -quality voice, images and Internet services of the astronauts and the ground, which is no different from the ground.

Ground light transmission combination

A high -speed "bridge"

In this launch task, ten are the Long March 5 Yao Three Rockets with the front -end video light transmission equipment, back -end video light transmission equipment, front -end radio frequency light transmission equipment, and rear -end radio frequency light transmission equipment. This ground light transmission The combination of the "bridge" of signal transmission between a stand -alone comprehensive testing equipment, technical positions, launch position tower, and rocket response machines. It provides high -speed channels for data transmission processing through long -distance light signal transmission.

T0 console and current equipment

Provide time frequency benchmark

The T0 console is an important device installed in the launch field system to obtain the rocket take -off contact signal, generating take -off T0 time and transmitted to the hair control center, command center and measurement control system. It can be said that the computing accuracy of the rocket flight ballistic at all times the deviation of the calculation accuracy of the rocket flight balloton is the key factor for the correct execution of the rocket flight.

From launching, tracking, docking, separation, to returning to land, the equipment of the entire manned space system needs to work simultaneously at a unified time and unified frequency, just like a person's heartbeat pulse. Shi Tong equipment takes such tasks.

Shi Tong equipment assumes the role of "time commander" and plays the role of "pairing", providing standard time signals and standard frequency signals for various user equipment in the entire system, so that user equipment scattered in various places in the unified time of time in a unified time Work simultaneously under the benchmark.

It is worth mentioning that the aerospace system is distributed in various launch centers, aerospace flight control centers, relay satellite control centers, satellite measurement centers, and various measurement and control stations, and measurement of the time -frequency unified system on the ship. The accuracy has reached 3000 years of error no more than 1 second.
