Stay up late, change the code ... his youth is busy but not messy

Text ｜ "China Science News" reporter Ni Sijie

The sky is already bright. Near the Zhongguancun Park of the National Space Science Center of the Chinese Academy of Sciences (hereinafter referred to as the Space Center), the breakfast shop in the hutong is the fragrance of buns.

The sunlight sprinkled the messy march bed in Zhou Hai's office through the glass window. On the side of the marching bed, Zhou Hai and his colleagues were lying on the desk, his face almost buried in the computer. Their eyes are matched with the mouse on their hands, sweeping over the lines of the screen ...

This is an early morning in 2019. The deputy chief designer of the young space model sub -system system has been tormented for three days and three nights in the busy chaos.

This year, Zhou Hai was selected as "the nation's upward youth". He thanked those busy and suffering, which was the experience that made him busy without chaos today.

At the end of 2016, Zhou Hai was at the Xichang Satellite Launch Center. Interviewee confidence

torment

In 2019, Zhou Hai was 32 years old and had worked in the space center for 10 years.

Two days before they were developed on the star information processing load, Zhou Hai suddenly discovered that the data seemed to be wrong.

Zhou Hai's design developed on the star information processing load. As the sensitivity of satellite detectors becomes higher and higher, the amount of data passed by satellites has also begun to surge. Facing future satellite development needs, they begin to design and develop a new load. Prepare and compress data to improve transmission efficiency.

The difficulty of developing this on -star processing load is that under the constraints of satellite limited resources, the complex calculation of large -scale detection data is completed in a very short period of time. At the same time, the effect of spatial radiation effect on the reliability of the spatial radiation effect.

If there is a problem, find out the reason and find a way to solve it.

They used it for about a day and one night, eliminated the hardware problem, and locked the problem on the software code.

In the past 10 years, Zhou Hai has written nearly 500,000 lines of code, but it is not so easy to find a small loophole from 200,000 lines. Turn over historical data, each code ... After another two days and two nights, the vulnerability is still missing.

After a night, you will be delivered to the acceptance. You must not take any doubt to the sky. The time on the computer constantly urges Zhou Hai.

After repeated debugging, the code that looked less "pleasing" appeared on the screen, and Zhou Hai stopped the mouse spots on that line. "Is there a problem here?"

Lightly, it broke through the atmosphere of the office in the office like lightning. The colleagues went around and stared at the mouse spots.

"Yes, here!" A colleague sighed and lay down on the marching bed. "Finally, put it out!"

At that time, Zhou Hai had a kind of pleasure like game clearance. While preparing to modify the code and update the software, he encouraged everyone: "Persist in half a day, prepare for acceptance, and go out to eat together at night!"

The next day, the delivery of the load was smooth and the quality of the product was perfect. But Zhou Hai and colleagues did not go out to celebrate. They need to sleep more than eating.

teammate

Zhou Hai likes to eat. When the pressure is high, he has two ways to relax, one is to play, and the other is to eat.

Basketball, badminton, table tennis, it doesn't matter what to play, sweating; hot pot, skewers, stir -fried food, it doesn't matter, it's delicious.

In his team, everyone seemed used to stay together all day. After dinner together, they will play together, go back to the office to discuss the problem or write the code. Every year, the space center organizes badminton games. Their team scores are always at the bottom, but every year they still "abuse".

Zhou Hai likes his team. In 2010, when he graduated from Xi'an University of Electronic Science and Technology, Zhou Hai had already got an offer of a foreign company, but after chatting with the scientific researchers at the Space Center, he yearn for the vast universe and made him decide to come to the space center.

When he was a child, he was like many children, dreaming as astronauts.

In junior high school, his parents told him that when he was surgery of appendicitis, his first reaction was, "It's over, it won't go up."

Zhou Hai grew up in a very democratic family. His father worked in the railway department, and his mother taught Xiaoqin in the song and dance troupe.

When I was young, Zhou Hai learned the violin, but rarely pulled it when I grew up.

His mother never blame him, because in this family, interest is the motivation for everyone to move forward.

The relaxed and rigorous scientific atmosphere in the laboratory made him enjoy it. Sometimes, after a busy day, he realized when he was ready to go home: "Oh, at 11 o'clock!"

balance point

In 2011, Zhou Hai deeply participated in the first aerospace model task in life -the design and development of the first star information processing load of a scientific detection series satellite in my country.

At the end of 2016, Zhou Hai came to the Xichang Satellite Launch Center with the carrier of the design.

On the night of the Rockets, Zhou Hai experienced an unforgettable insomnia in his life. The load he was responsible for the first time on the sky, and what would happen after going up, no one could guarantee.

According to the plan, the load should not be turned on on the seventh day after the satellite.

After seven days, the load was turned on. Seeing the normal passed data, Zhou Hai's stones in the heart of Zhou Hai fell to the ground.

The success of this task made the team realize that no matter how complicated the work is, it is always possible to do what I was looking forward to through persistence and hard work.

For this young team that has begun to achieve the "from 0 to 1" breakthrough in the "0 to 1" breakthrough in the star on the Star, this success is a strong heart. Zhou Hai recalled this experience and said, "Seeing the data is normal, there is indeed a strong sense of accomplishment at that time. When testing at the base, it also produced a sense of mission. Send it smoothly to the sky. I used to hear people's sense of mission, this time I really felt it. "

After the successful development of the load, the user unit also put forward new demand. From 2016 to 2020, Zhou Hai participated in the load development project of the intelligent information processing direction on the four stars.

In 2019, the three days and three nights when Zhou Hai was sleeping, it happened before one of the loads.

The first time in life made Zhou Hai slowly adapt to the completely different work rhythm from the school laboratory.

In those years, the detours, the codes that had been changed, and the night he had gone grew up with the load he was responsible for developing.

At present, Zhou Hai and the team's main on -star intelligent information processing load development technology level has reached the leading domestic leader.

"Innovation will bring more uncertain factors, but we need to ensure its reliability, which needs to find a balance point." Zhou Hai told the China Science News.

Zhou Hai also found his own balance point. After experiencing tension and panic, he was young and had cultivated a panic, calm and calm.

As more and more loads are sent to heaven, the team's reputation is becoming more and more loud in the industry, and there are more jobs. Today, Zhou Hai, an associate researcher of the Space Center, performs six research tasks and 2 pre -research tasks at the same time.

"Pre -research projects are our lifeline, and it will make our load more intelligent." Zhou Hai said.

This year, after being rated as "the nation's upward youth", Zhou Hai felt: "We are moving towards the second century -old struggle target of building a socialist modern power in an all -round way. Young people should contribute their own strength. , Science and Technology Power. "

"If you have a child in the future, will you let him work like you, do you often work overtime?"

Hearing this problem, under the dark eyebrows of Zhou Hai, his eyes laughed into two bends: "It depends on his interest. The combination of career and interest can be happy."
