Qi Tian's experimental cabin launch successfully depends on Chengdu's strength hardcore escort

At 14:22 on July 24, 2022, the Long March 5 Yao Three Lauret Rockets were equipped with the "Tiangong" space station and the Tiangong Experimental Curm was successfully launched at the Hainan Wenchang Launch Center. The reporter learned from the Tenth Research Institute (referred to as "Zhongdian Ten" in Chengdu) in Chengdu that in this dream -seeking journey, a number of equipment and systems of CICC contributed scientific and technological power.

A new generation of comprehensive test control system

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

It is reported that the Luhai Tianji test control communication system led by Zhongdian Ten Institute has 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 with the ground is like the kite line of the kite, so it is also called the "lifeline" of the spacecraft.

The new generation of comprehensive test control system mainly includes three characteristics of "intelligence, nationwide, high reliability".

"Intelligence": First of all, it is "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 health status.

"All -NPC": In the new generation of measurement and control systems, from software to hardware, from basic components to the whole machine and system, it has all realized localization. Now the stability and reliability of domestic operating systems and domestic meta -devices have been greatly improved. It can be said to be assured and comfortable.

"High reliability": In addition to the aforementioned resource reorganization technology, deep comprehensiveization 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".

Ground light transmission combination

A high -speed "bridge"

In this launch task, CLP Ten Institute for the Long March 5 Yao Three Rockets supported the front video light transmission equipment, the back -end video light transmission equipment, the front -end radio frequency light transmission equipment, and the rear -end radio frequency light transmission equipment. This ground The optical transmission combination set up a "bridge" of signal transmission between a stand -alone comprehensive testing equipment, technical position, launch position tower, and rocket response machine. 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. The current system has played the role of "pairing". With the accuracy of 1 second of 3,000 years, it is "precise synchronization" for user equipment scattered in various places to provide standard time and frequency signals.
