During the two months when Miao Wei's team was busy with the ECU control system, Song Qingwei and Zhu Tao's teams were not idle either.

Before this, they had arranged the network cables in advance and installed smart furniture and appliances, so everything was ready but the east wind was not available.

Of course, because the project volume is very large, the actual work is done by Master Wang’s decoration company, and they only provide technical guidance.

In the past two months, their two teams have been working hard to polish the smart home system.

There is always a gap between theory and practice. There are many problems encountered. You need to modify and set parameters according to actual conditions.

For example, if you automatically open doors and windows, you will have an extra value, which will cause the doors and windows to be in place and the motor will still be running, causing the doors and windows to constantly bump into, like a ghost hitting a wall.

If one value is missing, the doors and windows will not be completely opened.

In this process, it is more important for them to summarize the parameter setting methods so that they can compile a technical manual so that Wilson's construction personnel can easily master it.

The most difficult thing is the adjustment of the intelligent voice control system. The technology here is very difficult and has involved primary artificial intelligence technology.

That is, fuzzy recognition technology allows computers to recognize less standard Mandarin. There is no end in this regard, only better.

Each of their teams of 200 people had to issue various instructions, and even deliberately issued less standard Mandarin to increase the technical difficulty and solve the problem when encountering problems.

They spend most of their time adjusting speech recognition.

The second major problem they encountered was the problem of far-infrared laser positioning technology.

The far-infrared laser is the red light we see on TV, the infrared alarm device in the bank vault.

That was deliberately displayed for the audience, but in fact, the far-infrared laser cannot be seen by the naked eye.

There is also the remote control of the TV set, which is far-infrared laser, but it is scattering, and here it needs to be concave mirrors to form a thin line.

Why did Song Qingwei and others choose far-infrared laser? It is mainly because it is cheap and harmless to the human body, but it is beneficial to the human body. For example, some far-infrared physiotherapy products are developed based on the principle that far-infrared rays can stimulate the activity of human cells.

Another indoor positioning distance is not far, as long as there is a positioning distance of ten meters, it is enough, so far-infrared laser is the most suitable and economical solution.

It's not a problem of measurement accuracy. They have solved this problem long ago. It can be improved while doing experiments without a computer.

The problem they are facing now is the problem of tracking in real time with people.

It is impossible to install laser generators and receivers all over the room, as that would be too expensive.

So they designed infrared tracking devices that can shake their heads at 360 degrees, just like the 360 ​​degree surveillance cameras today.

However, the surveillance camera is constantly spinning, and this infrared laser tracker must be synchronized with people and does not move normally.

The solution is infrared induction technology as a positioning technology. The human body surface also emits infrared rays at all times. Fix the infrared sensor and the laser emitter on one surface and drive the micro motor to rotate with the person, so that real-time tracking and real-time positioning can be achieved.

The principle is very simple, but there are many problems actually encountered, such as because the house is not round, there are corners and obstacles, and there are always blind spots in positioning, etc.

However, no matter how many problems there are, there are many people and great power. With the efforts of more than 200 people, it has been solved in the past two months, and it has basically had practical value.

Because Song Qingwei's team renovated the office building every day, Wang Yong knew what they were busy with, so he didn't ask, just one morning two months later.

When Wang Yong rushed to work, he saw that the square outside the office building was full of people, and everyone was talking fiercely about something.

Wang Yong suddenly felt unhappy. At this time, Song Qingwei and Zhu Tao were excited to greet him.

"Boss, from today on, the intelligent control system of the office building will be officially launched. Everyone is waiting for you to try it out first!"

When Wang Yong heard that this was the case, he was immediately happy.

"Is that so? OK! You two give me technical guidance and tell me how to use it. I am a person who doesn't know any technology at all. If I can use it easily, I believe there will be no problem."

Wang Yong did not stop. He walked towards the office building gate as he spoke.

At this time, Song Qingwei stopped him: "Boss, you will have to punch in fingerprints from today, otherwise the door will not be opened automatically."

"Oh!" Wang Yong stopped hearing this. He looked at the fingerprint recognition table that had been installed long ago. Sure enough, it changed. It turned out to be a ring button, but now it has become a flat stainless steel plate. In the center of the stainless steel plate, there is a fingerprint-shaped pattern.

Wang Yong walked over and pressed his right thumb, and heard a sweet female voice in the speaker installed at the gate asking: "Please report your name so that you can register your fingerprint data."

"Wang Yong" Wang Yong replied casually.

"Hello, boss! Please press your fingerprint again to confirm." The smart voice immediately recognized his identity and changed the boss's name.

This is because the smartwatch that Wang Yong wore has already shown his identity. The computer can identify twenty people at a time, but it is not certain that Wang Yong is a certain person.

Wang Yong pressed his fingerprint and made a sound to confirm, and the computer could determine his identity.

Wang Yong pressed his handprint again as he spoke.

"Boss, your fingerprint data has been established, please press the fingerprint again to check in."

Wang Yong pressed his fingerprint again as he spoke.

"The check-in is successful, and it is now 8:52 in the morning. I wish you a happy day."

The smart voice reminder check-in was successful and the accurate time was reported. At the same time, the glass door opened in response to the sound.

At the same time, Wang Yong's smart watch also vibrated slightly, prompting that he had successfully checked in.

The entire dialogue process seems very complicated, but it is actually a dialogue that has been set up long ago. It is just that the name changes according to the person. For example, others do not call the boss, but call Mr. XX and Ms. XX.

This is just the first conversation during fingerprint modeling. When you are busy, there will be no conversation, and you will only jingle. Because there are too many people, it will cause a crash due to too much calculation.

Technically, it is not complicated. It is all pre-recorded pronunciation dialogue. The key is that the pronunciation should be fresh and natural, so that people cannot hear the voice emitted by the machine. This requires engineers to carefully adjust it.

After Wang Yong registered and checked in, Mo Qingying inserted it. She was the second to perform fingerprint modeling. The process was exactly the same, but she changed her name.

The whole process was very fast, and it took less than half a minute, so the employees took turns to register and check in.

After Wang Yong left, everyone was afraid of being late and rushing to register one in a few seconds. The computer conversation could not proceed and it was automatically closed, but instead it was changed to a jingle prompt.

It seems that engineers have also considered this issue so that the computer will not crash.

On the other hand, it also reflects the powerful data processing capabilities of the Huaxin 401 chip. In fact, the main control computer of the smart home system is a high-performance server.

As mentioned earlier, Huaxin 401 has a unique function, which is the distributed computing function, which can use computers in office buildings to process data to disperse busy computing pressure.

Therefore, it can be easily dealt with in dealing with this special situation where multiple people continuously recognize it.
