The world's richest man started by developing gutter oil

When the electronic lock was displayed on the big screen, the staff pushed up the two display doors.

"Is there any friend who would like to come over and try our product?" Han Chen asked with a smile.

After hearing Han Chen's words, many boys raised their hands immediately. Boys are still very interested in technological products, not to mention such advanced technology. Han Chen also selected five viewers from among many people.

After the five audience members came on stage, the staff recorded their faces and introduced them.

The cameraman also immediately forwarded the picture to the big screen and live broadcast room. Many people were amazed when they saw the way the facial recognition lock was used. As long as they walked to the door, the door lock would automatically open the door. This design is very useful for people. It was too advanced for them.

However, some imaginative viewers in the audience raised a question.

"Emmmm, if someone holds me hostage and the door of my house opens so easily, isn't this inviting a thief into the house?"

"Brother, you have been held hostage. If you use a key lock and they don't let you use a key to open the door, what do you think is the difference?"

"It seems to be the case."

"This brother's brain circuit seems to be a bit extraordinary."

"However, this facial recognition unlocking method is really convenient. You no longer need to carry a key when you go out. Even thieves are a little confused when they look at this lock."

"There is no keyhole and if you ask him to open it, he won't know how to open it."

"I believe that many people have encountered the situation of leaving garbage when they went out. The door was blown shut because of the strong wind, making it impossible for them to enter the house. Or they forgot to bring the key or something when they went out. In the end, they had to find a locksmith. The master came over to help unlock the door.

Especially for those friends who often forget to bring their keys, it is very distressing to open the door for tens of dollars at a time.

But if you use our facial recognition electronic lock, you no longer have to worry about this problem.

You can easily open the door of your home with just one face. Of course, in addition to face recognition, our electronic lock also supports passwords and electronic cards for unlocking. If relatives come over but you cannot return home immediately .

You can tell your relative the unlocking code and ask him to unlock the door first and wait at home, so that you don't have to rush home all the way.

Is this kind of electronic lock very convenient? "Han Chen said with a smile.

The audience in the audience nodded when they heard Han Chen's words, and some people even said the word "yeah".

At the same time, Han Chen invited several spectators who had already experienced the dark blue electronic lock, and the staff also brought them to Han Chen's side.

"I wonder what you think of our facial recognition electronic lock?" Han Chen asked.

An audience member raised his hand and a staff member handed him the microphone.

"Hello, Mr. Han, my name is Xia Qi. I would like to ask whether this electronic lock uses AC or battery. What should I do if the electronic lock runs out of power?" Xia Qi asked.

"Our electronic lock uses 6 AA batteries. We have installed a photosensitive sensor on the electronic lock. Our electronic lock will only be reactivated when the light is blocked. Under normal conditions, our electronic lock They are all in a sleeping state, so the electronic lock requires very little power.

Under normal circumstances, a set of electronic locks can be used for one year. If the battery of the electronic lock accidentally runs out, there is a USB interface under the electronic lock, and a power bank can be used to power the electronic lock, so that the user can open the door lock again and replace it. Battery.

In addition, we also designed a hidden physical key code lock, which means that users can also use a spare key to open it, provided that you know the password of the physical lock.

This prevents master lock pickers from using physical keys to force open electronic locks. "Han Chen explained.

"What if the thief picks the lock directly?" Xia Qi asked again.

"Our lock cylinder and lock head are all made according to the national C-level standards. It is impossible to pry open the door lock. Moreover, our electronic lock has an anti-pry design. If a thief wants to pry open the panel and open the lock, he has to pry. The electronic lock will emit a loud alarm sound when it is opened for a while, and the alarm sound of the electronic lock is enough to scare away thieves.

Moreover, the camera of our electronic lock will take a real-time photo the moment it is opened. If the thief's face is accidentally photographed, you can directly take the photo to the police station to report it.

In addition, if a thief tries to unlock with a password lock, when he enters the wrong password, our electronic lock will also take a photo and will remind the user when he returns. You only need to find a disk and insert it into the door lock. USB, and then transfer the photos to the USB flash drive through the system menu. "Han Chen said with a smile.

"Thank you, Mr. Han for your answer, I have no questions." Xia Qi replied.

At this time, another audience member raised his hand, and Xia Qi handed him the microphone.

"Mr. Han, I would like to ask what the price of this electronic lock is?" Yuan Shaoxian asked curiously.

"Our electronic locked price is 2999 yuan. Within one month after the press conference, everyone can enjoy a 1499% discount. It only costs [-] yuan to purchase. Friends in need can log in to Goudong to purchase.

Maybe you think our electronic lock is very expensive. You can compare it with other brands of electronic locks. The most common password electronic lock from Samsung costs 3499 yuan. Our facial recognition electronic lock can be said to be very affordable. .

In fact, you can think about this problem in another way. A door lock can be used for at least ten years, and ten years is 650 days. If you purchased the electronic lock during the promotion period, it will be calculated based on ten years. , the daily usage fee is only [-] cents.

We will provide five-year free warranty service to all users. After five years, we will also provide paid warranty service to ensure that each user's electronic lock can be used for ten years. " Han Chen replied.

Although Han Chen has discounted the price by [-]%, many people still think that the price is very expensive, mainly because of income issues.

"The price is a little expensive. A lock is almost half a month's salary for me."

"This thing is not for us ordinary people to use. It is obviously for those rich people. We still lock it with ordinary keys."

"Don't say it so absolutely. I think what Mr. Han said is right. If a lock really lasts for ten years, it will only cost a few cents a day."

"That's right, it's normal for a lock to last for ten years. Besides, they also provide a five-year free warranty. Even if it breaks after only five years of use, the cost is only 1 yuan a day."

“It’s something you can still afford if you bite your tongue.”

"Thank you, Mr. Han, for your answer. I don't have any more questions." Yuan Shaoxian replied.

"I wonder if the others have any questions to ask?" Han Chen asked with a smile.

After several other people shook their heads, the staff sent them off the stage. When the staff sent them off, each person gave them a gift bag.When they received the gift bags, they found that they were quite heavy, but they were still at the event, so they didn't open them to take a look.

"I didn't expect to go up to ask questions and get gifts. If I had known, I would have gone up too."

"If I had known it earlier, why wouldn't there be so many people? If I had known it earlier, why didn't you raise your hand just now?"

"What is the gift you gave Deep Blue to them?"

"What it is has nothing to do with you, it's someone else's thing, okay?"

"The introduction of the electronic lock, the first product of the press conference, is over here. Let us introduce today's second product. I believe many people have the second product at home, but our product once again stands out in terms of technology. leading the world.

It is not an exaggeration to use the word "far ahead" to describe it. Our second product is the Deep Blue Starlink wireless router.

In September this year, the WIFI Alliance released the 9n protocol. Maybe you don’t know the meaning of this name. To put it simply, it is the fourth generation WIFI.

The International WIFI Alliance released the fourth generation of WIFI in September this year. The fourth generation of WIFI introduced MIMO technology. The theoretical maximum transmission speed is 9Mbps, which is significantly improved compared to the previous 600Mbps. The transmission distance of WIFI has also been greatly increased.

MIMO technology allows the fourth generation WIFI to connect multiple devices at the same time.

The biggest advantage of WIFI is that it allows us to avoid the trouble of wiring. We can enjoy wireless networks even without network cables. With the development of technology, more and more devices can use WIFI.

For example, smartphones, laptops, Itouch and other devices can access the network through WIFI.

But is the fourth generation WIFI released by the WIFI Alliance really the most advanced technology?

I can tell you that the answer is no. Starlink technology developed by Deep Blue Semiconductor is currently the most advanced wireless network technology. "When Han Chen said this, the parameter comparison chart of WIFI4 and Starlink appeared on the projector behind him.

“Although the fourth generation introduced MIMO technology so that WIFI can connect to multiple devices at the same time, the fourth generation WIFI can only transmit signals to one device at a time. That is to say, when two people use WIFI at the same time, only one person can connect to WIFI from the WIFI. Get the data there.

If the other party just browses the web page, it may not have much impact. If the other party uses WIFI to download files, then you can only use WIFI after he finishes downloading.

However, our Starlink technology has added a technology called MU-MIMO, which you can understand as an upgraded version of MIMO technology.

With the support of MU-MIMO, Starlink wireless routing can transmit signals to multiple devices at the same time, completely solving the problem that fourth-generation WIFI can only transmit signals to one device.

As mentioned just now, the maximum theoretical transmission speed of the fourth generation WIFI is 600Mbps, but the Starlink technology developed by Deep Blue Semiconductor is as high as 1GMbps.

To put it simply, the maximum theoretical transmission speed of the fourth generation WIFI can reach 7M, but the Starlink technology developed by Deep Blue Semiconductor can reach 125MB.

That is to say, the transmission rate of Starlink is 17 times that of the fourth generation WIFI.

The transmission range of the Starlink technology developed by Deep Blue Semiconductor is three times that of the fourth generation WIFI. In addition, the Starlink technology delay has been reduced from the third generation 3MS to 100MS.

Compared with the fourth generation WIFI technology, Starlink technology allows you to not feel any delay. Starlink technology makes you feel no different from a wired network when using it.

This is the wireless network transmission rate with the fastest known transmission speed, the lowest delay and the widest coverage in the world.

We, DeepBlue, are far ahead of the world in the field of wireless networks. "Han Chen said.

The audience present applauded after hearing Han Chen's introduction. Although this thing is useless to some people, Deep Blue's feat deserves their applause.

"I believe friends who are watching the live broadcast have many questions about our Starlink technology. For example, whether Starlink wireless routers can only be connected to Starlink technology. Our Starlink technology supports backward compatibility. If your device uses the In terms of fourth generation WIFI technology.

Our Starlink router can also be connected, and it does not affect the fourth generation technology compatibility issue.

Some friends will ask if Starlink technology is only used by Deep Blue. You don’t have to worry about this. You can take a look at the big screen behind me.

Manufacturers such as Fruit, SONY, Sanxing, Toshiba, Panasonic, Asus, Lenovo, HP, Dell, Qualcomm, etc. are all our customers.

They will use Deep Blue's Starlink technology in the next generation of products, so you don't have to worry about not having corresponding product adaptations after purchasing our products, because no one can refuse such advanced technology.

Of course, our Starlink router is more than just a little thing. I believe everyone knows that Deep Blue Network Security Company is a company under our Deep Blue Group.

Simply providing a high-speed wireless network product to customers is not perfect for us.

Therefore, we integrated Deep Blue Network Security’s firewall technology into Starlink routing.

"Han Chen Balabala began to introduce the firewall function on its routing.

Most of the audience was confused because the knowledge was beyond their scope of knowledge, but they knew what Han Chen was talking about.

Han Chen was telling them that DeepBlue's Starlink router was very powerful, and these functions were not available in other wireless routers.

After introducing the protective function of the router, Han Chen introduced the hardware configuration of the router to the audience.

What dual-core processor, 64MB of memory, two 2.4G signal amplifiers, 6 antennas, 5 Gigabit network card ports, etc.

Most people don't have any idea about this thing, but some colleagues who are watching the live broadcast know that Deep Blue's routing is really awesome, and it is really full of materials.

"I believe everyone is very curious about the price of our router. Our Starlink router is so much more expensive than other routers, but it can bring you the ultimate network experience. The price of our wireless router is 499 yuan soft sister coins.

If you want to use our Starlink technology on your desktop computers and laptops.

Then you can purchase our matching wireless network card, whether it is a PCI-E wireless network card used on a desktop or a mini wireless network card used on a laptop, the retail price is all 149 yuan. "Han Chen said.

At the same time, the large screen behind him displayed pictures of the two graphics cards. (End of chapter)
