My "King" gold coins can be withdrawn

Thank you very much indeed.

At this moment, the wooden door of Su Jing's bedroom has been removed and replaced with a metal door.

It looks a little different now.

It is more high-end and upscale.

Others are wooden doors, our house has metal doors, but it is different.

Then it's time to install the smart lock cylinder.

Su Jing turned on the computer, turned his mobile phone to the computer, and said, "This is the smart access control lock system we wrote. It was completed by a few of our friends. It has been installed in the lock cylinder just now... The next step is to put the lock Install the core and do a test."

"This was written by Su Jing and Tan Yi, I just made soy sauce!"

"Indeed, Sun Gaojie and I didn't help much!"

On the side, Lin Weicheng and Sun Gaojie heard from Su Jing that the access control system was completed by four friends in the dormitory.

The two of them said that they did not contribute much.

Although they are both academic masters, in terms of computer technology, Sun Gaojie and Lin Weicheng are not as good as Su Jing and Tan Yi.

It is also difficult for them to write a small software independently.

After all, I was only a freshman, and I learned the basics of the basics.

"That's helpful too, isn't it?"

"Not much to say, install the lock cylinder directly, and then test..."

The lock cylinder was handed over to the postgraduate seniors of the School of Mechanical Engineering. The door locks and doors they built were also very skilled in installation.

After the installation was completed, Su Jing used a computer to conduct a simple inspection and debugging.

When the system was installed just now, relevant debugging was done.

Now that the door lock is installed, we have to try it to see if all functions are normal and whether the door lock can be controlled.

"DiDi~!"

Accompanied by a sound, it marks that the entire smart door lock has been debugged.

Tan Yi stood up without hesitation and started to do related tests.

Enroll your fingerprints first!

human face!

Then swipe the card and enter the NFC system of the mobile phone, and the lock can be unlocked directly with the mobile phone in the future.

Then it's time to witness the miracle! !

Su Jing also left from the computer, stood at the door of the dormitory, and broadcast live to Tan Yi on his mobile phone.

Tan Yi close the door!

Then press your thumb on the fingerprint recognition template;

"Didi~click~!"

Accompanied by a mechanical sound and the sound of the door lock opening, the bedroom door has been opened;

"Ok, Ok!!!"

Tan Yi looked very happy and excited.

At least to prove that the system they wrote themselves is no problem in fingerprint identification.

The response is also very fast and sensitive.

Then test the face recognition system!

Also very fast.

Similar to fingerprint recognition.

This shows that the relevant algorithm written by Su Jing is very strong! !

The other students watching the excitement outside the dormitory may not be able to see what this means.

The leaders of Su Jing and their departments, as well as the boss of the graduate students of the School of Mechanical Engineering... naturally know what this means.

Su Jing and the others are amazing young people! !

Although the entire smart access control lock was commissioned by a laboratory here at Tsinghua University, the chips used are of course not researched by ourselves, but are some chips on the market.

The software system is made by Su Jing and the others, and it looks very strong.

Just like mobile phones, many mobile phones also use Qualcomm chips, and the systems are deeply customized by major manufacturers;

The smart locks on the market are also their own software technology + chips from other companies.

Su Jing and the others are only freshmen! !

The recognition speed of the smart access control lock system written is quite fast, which is not worse than the products of those big companies on the market.

Now it's time to test the security!

The recognition speed is fast...it may be that the software is very strong.

It may also be that the software is not well done, the recognition accuracy is not high, and the recognition speed is so fast.

Test the security next! !

These functions of NFC are very simple, just a simple test.

Next, Tan Yi used the fingerprints of other fingers to unlock the lock... Because the other fingers did not record fingerprints, all unlocks failed.

Other students who did not enter their fingerprints came to do the test, and they all failed to unlock!

The human face is covered as well!

All failed!

Su Jing and the four of them all recorded their faces and fingerprints.

The other students tried it again.

Enter more faces and fingerprints... In this way, maybe there will be similar fingerprints or face shapes, will it be fooled?

Still all failed!

It proves that the software system of this smart access control lock written by Su Jing is quite powerful.

Especially the core algorithms of fingerprint recognition and face recognition.

Chapter 245 Four Zero One Technology Company

The door lock has been tested and the effect is quite good.

It is a university after all.

Students in other dormitories also want to make one... It's a pity that the cost of this door lock is not included in Su Jing's software system development cost;

Just the processing and manufacturing of smart locks, various parts and chips, etc., cost several thousand.

As for this iron door, even though it was given by a graduate student from the School of Mechanical Engineering, the cost will not be too cheap, maybe a few hundred yuan? !

Maybe even higher.

This is not something the students in the dormitory can afford.

It is also impossible for the school to spend a huge price to change the door lock of the school dormitory.

The price is too high.

And it's completely unnecessary.

It's just that Su Jing and the others are playing around with themselves, using the knowledge they have learned in college to create such a smart lock and replace it, the school still encourages and supports it very much.

Next, test the remodeled air conditioner and bedroom lighting.

Lighting can now be controlled from a mobile phone.

An electronic thermometer is installed in the dormitory to test the room temperature and air humidity and so on.

Now the air conditioner is connected to the smart door lock system written by Su Jing and the others, which automatically detects the temperature in the city, and then turns on the heating or cooling of the air conditioner.

Of course... when there is no one in the dormitory, this function will definitely not be activated.

Otherwise, if there is no one in the dormitory, the air conditioner detects that the temperature in the city is too cold and automatically heats up. That is not a waste of electricity.

The overall test can be said to be perfect! !

In the future, this smart door lock system...or simply called a smart butler system?

It is also very convenient to connect to other smart home devices and control them.

This smart butler system was simply written by Su Jing and Tan Yi, and it will be upgraded and optimized later.

Later, some other functions can be added to open the access ports of other smart devices.

"Very good, learning should be to apply what you have learned..."

The head of the department watched Su Jing and the others change the door and lock of the dormitory, and gave an encouraging evaluation.

For students, the school is more supportive if they can make some gadgets with the knowledge they have learned.

What's more, the access control lock made by Su Jing and the others is not low in technology.

It can be said to be quite good.

It's just Su Jing and Tan Yi... well, it's mainly because Tan Yi has nothing to do.

At that time, Su Jing went to South Korea to participate in a competition, and he had no idea about animation production software and special effects production software.

I just thought it would be troublesome to go back to the dormitory every day to open the door and turn off the lights.

Thinking of this, he started working on a control system.

When Su Jing came back from the competition, he helped him complete the system.

It's really just for fun.

Serious work is still designing and developing action production software and special effects software.

but……

"Really want companies to buy our technology?!"

The next day, Su Jing received news from Yu Jiamei.

There is a company that really wants to buy the "smart butler system" for the door developed by Su Jing and a few roommates, which is actually an access control lock system.

Su Jing cannot be contacted by those companies.

They can only contact the external link department of Su Jing's company: Yu Jiamei is in charge.

"It really is!!"

It's not just Su Jing's side.

Tan Yi said: "The seniors from the School of Mechanical Engineering also contacted us, saying that a company approached them and wanted to buy the smart lock-related design and software technology we designed, and asked if we would like to sell it..."

"Actually... the school wants to buy it too!"

Tsingtao actually has its own industry.

And it's a pretty huge industry!

The assets managed by Tsingta Holdings are as high as hundreds of billions, and there are several listed companies under its umbrella, many of which are leading companies with a level of hundreds of billions.

how to say!

The smart door lock made by Su Jing and a few friends has some technical content.

But it will definitely not be said to lead the entire market.

Compared with some other smart door locks with high reputation and high safety factor on the market, there is still a gap.

Why are so many companies interested?

This is about Su Jing's popularity and popularity.

Su Jing's popularity and popularity can be said to be different from the past.

After participating in domestic swimming championships and archery championships, Su Jing's popularity has almost reached a peak, and he received a $1 million endorsement from Coca-Cola.
