As we all know, contemporary aerospace engineering is a very large-scale system engineering, which requires excellent performance in the fields of computing, electronics, and control to be competent for this series of work. Throughout the operation of the aerospace tools, automation control has always occupied the mainstream of the project, through which to achieve the smooth operation of the spacecraft.
The spacecraft in our impression, especially the spacecraft-like space tools, should be able to directly control flight through astronauts, but due to practical technology, most of the earth-revolving aircraft are issued by ground commands and the automatic control of the spacecraft itself. carry out.
At present, in China's manned spaceflight project, the Shenzhou series of spacecraft and Tiangong-1 have completed flight missions in this form, and monitored the real-time status of the aircraft through distributed national monitoring stations.
In the live broadcast of God Ten ’s launch, when its solar windsurfing was unfolded, we could clearly hear the technical staff report the windsurfing command, and then clearly see that the windsurfing was quickly unfolded from the external monitoring probe of the spacecraft, again confirming the ground command and the spaceship The relationship between automation. In the fifteen-day on-orbit operation of Shenzhou 10, it will also be connected with Tiangong No. 1, which is another docking task after Shenjiu.
The docking is performed twice, once for automated docking and once for astronauts. As people in the automation industry, we care more about automation docking. The docking mechanism of Tiangong-1 has 118 sensors for measurement, 5 controllers send commands, thousands of gear bearings transmit force and motion, and operate through 14 motors and electromagnetic drag mechanisms. Tens of thousands of The parts and fasteners form a complex, mechatronically integrated peripheral docking mechanism with a manhole channel with a diameter of 800 mm in the middle. This kind of product with many moving parts, long transmission chain and high precision requirements must be completed by engineering design of system integration.
At the same time, the core part of the overall docking process must be automated control. No matter now or in the future, manual docking will be carried out, but manual is only a backup measure that will be taken when the hardware and software of the space equipment is faulty in the harsh space environment. Most of the normal conditions are automatic control.
In the future, with the continuous breakthroughs of many basic technologies, automation will be the key development direction in our scientific research and industrial production, and there is no one.
