Who can guarantee that no other satellites will be affected by extreme solar activity in the future?

During this period of time, Xu You has also been working hard to find a suitable solution.

Xu You's idea is to create an early warning system for in-orbit satellite failures.

In this way, before serious failures occur, early warnings can be made, and operations such as satellite orbit changes can be used to avoid areas with intense solar activity.

Maximize people's safety.

The key to early warning is to analyze the law of changes in satellite telemetry parameters.

Telemetry parameters on the satellite, including voltage, current, temperature, pressure, count, equipment status on the satellite, etc.

Among them, there are real digital data and some analog quantities.

Some represent the state of the satellite itself, and some represent the state of the surrounding space environment.

If you want to use these data for early warning, you must understand the characteristics of these data in detail and be able to convert these data with actual conditions.

After mastering a large amount of satellite telemetry data, Xu You finally designed a complete early warning system through brain simulation and software assistance.

Not only can early warning of solar activities, but also include some other possible emergencies.

Xu You informed Yang Wu of the news, and Yang Wu was also very overjoyed.

"Professor Xu, are you saying that you have already made a satellite early warning system for solar activity?"

"Not only solar activities, but also other events including system failure, fuel exhaustion, accidental collision with space junk, etc., can also be used for early warning. If we have time, let's hold a meeting to discuss it."

"Now I will organize the meeting. If there are no core members with urgent tasks, I will call them over!"

The significance of this early warning system is very important, not only for our aerospace system, but also for the safety of satellites all over the world.

Yang Wu was also very excited, as if he was about to launch a rocket mission.

After everyone came to the conference room, Yang Wu said:

"Professor Xu just made a fault warning system for in-orbit satellites. Let's ask Professor Xu to explain this early warning system."

Hearing the news, everyone was very anxious.

After all, if there is such a set of fault warning system for satellites in orbit, many satellite faults can be avoided.

It is of great significance to ensure the safety of satellites.

At this time, they all focused their eyes on Xu You, looking forward to Xu You's explanation.

Xu You first talked about his own analysis of the changes in the data rules of satellite telemetry parameters.

"According to my summary and analysis of a large number of satellite telemetry data before, these data are roughly divided into one category. The first type is stable telemetry data, and the various telemetry data are maintained near a fixed value, which can indicate that the satellite is in a comparative In a safe state. The second is when there is no state and no measurement and control event occurs, the parameter change rate has a step change. This situation should be paid more attention to, and some abnormal situations may appear..."

At the beginning, everyone could fully understand what Xu You said.

Some of these early warning methods have been adopted before.

However, as the data and formulas involved gradually increase, the early warning method becomes more and more complicated. As we all know, this is indeed a very powerful technology.

"The prediction method of this satellite failure is to analyze the satellite data according to the satellite's historical data and real-time data, and the law of changes over time. By changing the parameters, I will make the curves of each polynomial Fitting, and finally got such a formula."

Looking at the complicated formula on Xu You's screen, everyone couldn't help but looked at each other.

"Professor Xu, can you tell me how to understand this formula?" Su Yiguo asked.

"Yes. When deriving, we must first select the appropriate fitting method model according to each parameter, and set the order of fitting. We assume that the conditions such as the structure and function of each subsystem of the satellite under study are Basically the same..."

Under Xu You's patient explanation, everyone finally understood Xu You's train of thought roughly.

At this time, Hu Shucheng asked:

"Professor Xu, according to what you said, this method is mainly suitable for periodic telemetry data that changes slowly over time. If it is in other situations, can this method accurately give early warning of satellite failures?"

This time, Hu Shucheng did not choose again, and went to discuss this issue with Xu You privately after the meeting.

With Xu You's entrustment last time, Hu Shucheng believed that Xu You really didn't care about the so-called face.

At this time, the most important thing is to try to solve all the problems at the meeting and further improve the entire early warning system.

Xu You didn't lose his footing because of Hu Shucheng's sudden question, because Xu You had already prepared for this question.

Xu You was also very happy that Hu Shucheng was able to directly ask questions at the meeting this time, instead of blindly taking care of his own face.

"Gong Hu's question is very good, and I'm about to explain it. The early warning system I made is not the only technology, but it is aimed at different types of telemetry data and automatically connects with suitable systems."

Hearing Xu You's words, Hu Shucheng also nodded repeatedly.

Sure enough, even what Hu Shucheng could notice, Xu You had already considered it.

"If it is a relatively complex time series with various patterns, that is, the non-stationary trend data prediction problem, we can use the summation autoregressive moving average model to analyze. Here, we use a relatively simple, but A very practical method - difference method..."

Immediately afterwards, Xu You explained several early warning technologies for satellite failures.

For each type of telemetry data, Xu You has found a corresponding early warning technology.

In this way, the greatest degree of protection can be guaranteed, and the system can give early warning of unexpected situations that the satellite may encounter in a timely manner.

After Xu You finished talking about his entire early warning system, the atmosphere at the meeting seemed very quiet.

Because for a while, everyone can't give any suggestions.

"Thank you Professor Xu for sharing. Do you think there are any questions?"

Commander-in-chief Yang Wu asked everyone, but he himself could not find any problems.

Seeing that no one raised their hands, Yang Wu continued:

"I think if there is no problem, let's start the trial operation of this in-orbit satellite failure warning system as soon as possible."
