Movie black technology

After ordering the meal, Chen Shen and He Changfeng communicated in the cafeteria for a while, and then they separated.

Go back to your dormitory.

Pushing open the door, inserting the data hard disk on his hand into the computer, and carefully checking the signal data inside again, he was completely sure.

In the experiment just carried out, the ten sensors did clearly and completely capture the ten photoacoustic signals generated by the mice.

This is the basis for moving forward.

Chen Shen breathed a sigh of relief.

It took so long to solve this problem. After the boxer was created, it was the first time to encounter a problem that had hindered him for so long, although there were special factors of the Spring Festival in it.

Now that the signal has been detected, the next thing to do is to write the algorithm and program for signal analysis to prepare for the subsequent human experiments, and strive to analyze the signal on the day the signal is obtained.

There is nothing to say about this.

Turn on the system, switch to the computer page, and just press the keyboard to do it!

While looking at the algorithms and program codes in the system, Chen Shen reproduced them on the computer.

He chose the simplest blood sugar algorithm in the system. After analyzing the signal with this algorithm program, the blood sugar value range of the test object can be obtained.

It's not that he doesn't want to choose other algorithms with more analytical information. The reason why he chooses this algorithm is still a reason that limits him.

The number of lines of code...

For other algorithms with complex functions, the number of lines of code will increase accordingly...

For example, the algorithm of body image construction has reached the point where he would be bald just by looking at it.

As for code, it is well known that it cannot be copied.

This Mediterranean boat ticket should be given to the programmers of the artificial intelligence center.

So he can only pick the one with the least number of lines of code to copy. Anyway, he only needs to make sure that the signal collected by the human body is usable, and he doesn't need to care too much about the analyzed data.

Among the materials currently released by the system, the blood sugar detection algorithm has the least code.

This algorithm is not complicated, but the specific program code was copied for more than two hours.

It's not that Chen Shen didn't think about optimizing this program, but after studying it, he found that the program proposed by the system was already the optimal solution, and there was no room for optimization.

He also had to be a code porter honestly.

He didn't finish the whole procedure until eleven o'clock in the evening.

As soon as it was finished, he couldn't wait to input the signal data of the mouse on the hard disk into the program for analysis.

【Invalid data】

"Sure enough, the analysis algorithm of mice is not the same as that of humans." Looking at the results on the screen, Chen Shen muttered to himself.

To detect the blood information of mice, it is possible to make additional adaptive transformations to the analysis algorithm.

In the photoacoustic signals produced by various living organisms, various influencing factors are different from those of human beings. For example, the analysis algorithm of the human body may be addition, while the analysis algorithm of mice may be multiplication.

Such a situation naturally cannot be resolved by human algorithms.

This is also a small shortcoming of the photoacoustic scanner. Before the algorithms of other creatures are perfect, it is not applicable to non-human life forms.

In order to improve these algorithms, a lot of research and experiments are required. This is a big project, and there is no systematic guidance in it.

Destined to be another Mediterranean ferry ticket.

As the holiday passed, the relaxed atmosphere in the base quickly dissipated.

People's footsteps became hurried again, and it was difficult to see people in the park during non-break hours.

And the members of the photoacoustic laboratory gradually returned to the base.

Chen Shen's previous three experimental assistants also returned to the laboratory.

When they heard that Chen Shen had carried out the signal acquisition experiment by himself, and it was successful, the three research assistants in Zhouzhuang didn't know what to say for a while.

"What we are going to conduct today is the experiment of obtaining the photoacoustic signal of the human body."

In the laboratory, Chen Shen was talking to the three people in Zhouzhuang, and He Changfeng was also on the side.

He left the rest of the team today and came here to observe this experiment.

Of course, according to him, he himself came to help.

"Is there anyone willing to be a test subject?"

As soon as Chen Shen's words fell, Zhou Zhuang raised his hand immediately without any hesitation.

The other two research assistants saw it and gave up too.

Chen Shen took out a consent form for the experiment.

"Although in principle, it is impossible for the scanner to cause any damage to the body, but to be on the safe side, let's sign a consent form."

There are various guarantees in the event of an accident in the subsidiary conditions of the consent letter.

However, Zhou Zhuang didn't even look at it, so he signed it without hesitation.

The white mouse has been scanned by the laser countless times under his nose, and it is even less likely that he, a human being, will worry about the safety of the photoacoustic scanner.

After signing the consent form, he walked into the laboratory and sat on the test chair.

The other assistant is responsible for starting the instrument outside.

"Are you ready?" the assistant asked Zhouzhuang.

Zhou Zhuang gave an "ok" gesture.

The assistant operating the instrument immediately activated the scanner.

squeak~

With the soft sound of the mechanical arm, the laser emitter aimed at Zhouzhuang, automatically avoided the clothes on his body, and quickly scanned the exposed skin.

As usual, within two seconds, the signal has appeared on the oscilloscope and converted into detailed data through the converter.

"Did it succeed?" Zhou Zhuang was still asking in the experimental area, and when others replied to him, Chen Shen was already checking the data in front of the computer.

"How is it? Is the signal reception complete?" Several other people and He Changfeng approached.

Faced with a large amount of data, Chen Shen directly took out a USB flash drive from his pocket, and said to his assistant:

"Install the program in the U disk, and then import the data just now."

"Ah? What is this?" The research assistant was taken aback for a moment.

"I wrote a signal analysis algorithm two days ago, which can analyze the blood sugar value in the signal." Chen Shen said, and took out a household blood sugar detector from his bag, and handed it to Zhou Zhuang to signal him to test it.

He Changfeng immediately said: "Quick, try it!"

The research assistant in front of the computer immediately took the USB drive, "Okay!"

Insert the USB flash drive, install the program, and import data in one go.

After the data was imported, the mainframe of the computer started to run crazily. Everyone at the scene could hear the sound, and then the results were displayed on the screen.

【7.8mmol/L】

Everyone looked at Zhouzhuang at this moment.

He had just put down the blood glucose meter in his hand, and he showed everyone the results on the blood glucose meter:

【7.9mmol/L】
