Asked the launch of the experimental compartment successfully, this time the "Gold Finger" of the "ignition" button was her

At 14:22 on July 24, 2022, Beijing time, the Long March 5 Yao San Launa Rocket was equipped with an experimental cabin and ignited at the Wenchang Space launcher.

In the testing hall, as the 01 commander shouted the "ignition" password for dozens of seconds with a calm voice, Liu Shuojie, the person in charge of the hair console, pressed the red "ignition" button to send out the last remote remote before the rocket took off. instruction.

This is the first time the hair console of the Wenchang launch site ushered in women's faces. The post is named "Golden Finger" because of the "ignition" button, but in fact, the work console involved is far more complicated than we see.

As the neural center of the rocket control system, the hair console requires the person in charge of their positions to have the overall thinking of the entire set of measurement processes. There are as many as hundreds of buttons on the console working panel. Each button represents a instruction. Nearly 300 parameters and status lights displayed on the workbench on the workbench are associated with the equipment of the rocket front end.

In order to meet the needs of the intersection of the Tiantian Experimental Curring and Space Station, the task has achieved the launch of the Long March 5 Rockets Zero window.

This is the first time that the launch site has performed large pushing low -temperature liquid carrier rockets to launch. At the same time, it is worth noting that the long five B is the most complicated type of rocket in my country at present. Therefore, this task puts forward higher requirements for the ability and quality of the head of the hair console.

"Zero window launch means that I want to be more familiar with the relevant emergency response situation. Every second in advance to find abnormalities in advance, I can get more time to correct it for the launch window." Liu Tujie said, "And the launch of the zero window launch At the request, compared to the automatic ignition process of other types of rockets, the manual ignition of the hair console can more flexibly control the rocket pre -shooting process, and it is more in line with the time accuracy required for the launch. "

As soon as the zero o'clock on July 24, Liu Tujie rushed to the test launch hall in the night.

Both Liu Tujie and her husband Li Fan are aerospace workers.

According to the test procedure, about 14 hours before launch, she will be in office. The first thing she did on this night was to confirm the status of the system instrument. Although these processes have been practiced countless times, they officially sat on the hair console seat on the day of launch, and once again made her feel "not disappointing this mission and trust."

Liu Tujie said: "The biggest challenge for this task to me is to quickly identify abnormal parameters." So after the Dinggang console, she immediately launched an offensive.

In the early stage, Liu Tujie designed the map to the Rockets, carefully analyzed the changes caused by the instructions, and which parameter abnormalities would be caused after the movement was abnormal. She and the rocket designer jointly study each circuit, classify the parameter values ​​of the current and voltage of some components. Each category is made into a small card. During the meal, the work gap, and before going to bed, take it out to see it.

Liu Tujie admitted that she prepared for seven years for the "ignition" button. "Every astronauts who work in the control system have a 'golden finger dream'." To become a "golden finger", you have to cross a lot of difficulties.

The first level is physical quality. In order to be familiar with the system work, Liu Tujie decided to practice all the positions in the control system. A considerable part of the work had higher physical strength for women, but she was not timid. In order to pull the cable, Liu Shuojie exercise every day to enhance the core force; in order to complete the operation of the high -altitude rod, she is afraid that she will go to the playground to try the roller coaster and pirate ship; the long -term umbilical cord tower work on the sixteen -layer umbilical cord can cause her to suffer for a while Knee effusion, infrared therapy and hot compresses have become her daily necessities.

"I don't have any essential differences with others. Even if you spend more effort, I can still do it in the end." Liu Tujie said that the job work should not have preconceived gender. In the process of experience in each position, Liu Tujie also set a small goal for himself: every time he experienced a post, he solved a problem. With excellent mathematical theory and programming performance, she hopes to implement scientific research.

Liu Tujie found that the control system in the post in the launch area was small. At the same time, observing the status of dozens of indicator lights in five cabinets is a great test of the staff. Therefore, she uses image recognition technology The key to the alarm can be found in time in the lobby. At the same time, after a large amount of data generated by the testing stages of the analysis system, she used big data technology to develop a data interpretation system to achieve one -click generating data and abnormal data at a glance.

In addition, Liu Shuojie also actively carried out project research such as rocket system simulation and wind farm data modeling, and wrote papers in addition to work, published more than 20 papers in the core journal.

After seven years after this sword, when Liu Tujie really sat in front of the hair console, she could confidently say: "I'm ready." The journey is still very long, and it will go to a more beautiful destination.
