Siheyuan: Through Sixty Bright Life

"Let's go on to talk about its scope of application. It can receive Chinese characters, documents, notifications, stock markets and other extensive services, and even be used as a terminal for telegrams and data networks."

"The sensitivity of Chinese character display or digital display is better than 10PV/M or 5PV/M, and the channel selectivity is better than 60DB (VHF frequency band). The digital display is not less than 12 digits, and the average trouble-free time is not less than [-] hours."

Director Wang said, "I don't understand these advanced data. Although I have heard of pagers, I still haven't figured out how they work."

"Then let me briefly introduce how to use it. For example, if you want to find A, but he is not at home, you can call the paging station, and you can say that A will return the call quickly.

"A will call you back on the public phone when he sees it."

"Oh," Wang Changzi thought for a while, "Understood, just send a message through the paging station, and then the person I'm looking for will know that I'm looking for him?"

"Yes, our current paging station works like this. It's just that it used to be numbers and could only send numbers. Now it can send Chinese characters, and the messages are clearer."

"It's amazing. It's unbelievable. There are such amazing things in the world."

"Many high-tech product ideas are derived from discoveries in life. Where there is demand, there is the motivation for research and development. This is the charm of scientific research."

After He Yuzhu finished speaking, the audience applauded.

Everyone's hands were red, but they still didn't want to stop.

Years of hard work finally came to fruition, so how can we not excite all engineers?

Because He Yuzhu's research and development not only changed the country's science and technology, but also brought them a bright road for Huaxia's scientific research.

Chapter 405 If something happens, you call me

After three days of experiments, the prototype was completed.

The first Chinese character BP machine developed by He Yuzhu finally came out.

The frame of the main unit is black, and there are red and green buttons under the main display, and four buttons beside it are up, down, left, and right.

At the bottom is the brand model, the name is why Torola's new generation of Chinese character BP machine.

He Yuzhu has been registered and is a communication product independently developed by Huaxia Kingdom.

Today, the May [-] Factory has gathered many top scientific and technological figures from China.

There are old leaders of the Chinese Academy of Sciences, leaders of scientific research institutes, and a large number of top figures engaged in scientific research.

The leader of the scientific research institute received a notice yesterday and asked him to go to the [-] factory for a meeting. Only after he came did he know that He Yuzhu had developed new communication equipment.

And it's been less than a month since they last met.

There are many people in the room now, and He Yuzhu is holding a pager for the final test.

After the test was completed, He Yuzhu took a deep breath, picked up the phone on the table and dialed the 126 paging station.

This seemingly simple dial actually ushered in a new era of communication and information in China!

After a while, Miss Paging answered the phone.

"Hello, Hannstar paging station, operator No. 28 is at your service."

"I want to call 4898473 and leave a message: If you have anything to do, please call back. My number is 1888888, and my name is He Yuzhu."

He Yuzhu picked a good number for himself, and this number will be with him for several years in the future.

4898473 is He Fushang's pager number. Because there are no pagers in the mainland and few people use them, he thought of calling He Fushang.

Someone asked He Yuzhu, "What should the paging station do after receiving your message?"

He Yuzhu said, "The operator will immediately input the information into the computer, and the transmitter will automatically send a signal to the air under the control of the computer."

Someone asked again, "Since the telegram sent by the paging station can cover a certain area, why can the BP machine in this area only receive calls to itself, but not other people's paging signals?"

He Yuzhu held the pager and said, "In the future, the pagers we produce will all have their own numbers, and these numbers will be stored in the computers of the paging stations."

"The information sent by the paging station contains this number, which can only activate the corresponding BP machine, and has no effect on other BP machines."

"Let me make a simple analogy. It's like the postman delivers the mail according to the user's house number, so there will be no mistakes."

When He Yuzhu explained this, the other party nodded repeatedly, and everyone present also understood.

After all, it’s a new thing, so it’s clear, why don’t you try it yourself.

Therefore, He Yuzhu's experiment just now is to show the usage of the product more intuitively.

The doctoral student and the engineer next to him said, "I don't know if the other party can receive the message."

The engineer said, "It's hard to say."

Although the old leader did not participate in the research and development of the pager, he still has a good understanding of many principles of the pager.

There was just one question that he didn't quite understand. He asked He Yuzhu, "Will the other party see the message you sent?"

"Yes, after the paging station sends a message and the other party receives it, my number will appear on the display screen of his pager, and he will call me..."

As soon as He Yuzhu finished speaking, the phone in the conference room rang.

In order to test the BP machine, the engineer in the factory put the phone in the meeting room.

At this time, everyone present held their breath and dared not make a sound.

He Yuzhu picked up the phone and said to the receiver, "Hi, I'm He Yuzhu."

"I'm Lao He. I saw you looking for me. Is this your pager number?"

He Fushang didn't believe that He Yuzhu had a BP machine just a few days after drawing the blueprint?

"It's my number."

"Did you buy it new?"

"This is a new type of Chinese character pager I developed, and today is the first experiment."

"It's the blueprint you drew at my house that day... Did you make it?"

"Yes, this number is mine. You can call me later if you need anything."

He Fushang put down the phone and was stunned for a long time. It was unbelievable that such a high-end BP machine technology was developed by He Yuzhu.

On this side, when He Yuzhu put down the phone, he faced the old leader and said, "Successful, he received it!"

Then, the conference room burst into thunderous applause.

The success of the pager experiment means that they have their own domestic communication equipment with independent intellectual property rights.

At this moment, many engineers excitedly ran over to hold He Yuzhu and cried.

These people are engaged in scientific research, and they know the hard work of research and development.

How many people are needed for some scientific research projects, or even the results that generations of scientific researchers have worked hard to develop.

And they witnessed the birth of this new type of technological product, and their inner excitement was beyond control.

Huaxia TV interviewed He Yuzhu in the director's office of the rolling mill.

The reporter took the microphone and asked He Yuzhu a question.

"How did you come up with the idea of ​​developing a BP machine?"

"It was also by chance. I saw a new BP machine bought by a friend from a foreign country, and I wanted to develop a domestic pager."

"Our country has this ability and talents in this field. We are no worse than foreigners. What we lack is opportunities."

"Nowadays, since the opening of Huaxia, the economy has developed rapidly, and to adapt to the high-quality living standards and the ever-accelerating pace of work, it is necessary to continue to popularize more advanced communication tools.

"This is the result of a country's development and progress, and it is also an irresistible step forward of the times."

After the reporter finished the interview, he went back and started making big news, because it was going to be broadcast on the seven o'clock prime time news.

When the reporter left, he told He Yuzhu that the news would be broadcast at [-] o'clock in the evening.

After the experiment was successful, reporters from various newspapers flocked to the [-] Factory to interview He Yuzhu.

The headlines on the front pages of major mainstream newspapers were all "China's first Chinese pager with independent intellectual property rights was developed by He Yuzhu, the director of the rolling mill."

He Yuzhu went back and told Guan Xiaoguan to watch TV.

In fact, this is not the first time he has been on the evening news at [-]:[-].

Yan Bugui heard He Yuzhu's speech when he turned on the radio, and he knew what pager He Yuzhu had developed.

He hurriedly went to find Liu Haizhong.

"Liu Haizhong, have you heard the news?"

Liu Haizhong had just finished his meal and was resting with his eyes closed.

"No, what's the matter, what's the big deal?"

"Pillar...on the news again..."

"Hey, this is still news. It's strange that he doesn't appear on the TV news for a month."

"It's not this one. It's the machine he developed. You can know when someone is looking for you when you walk on the road."

Only then did Liu Haizhong open his eyes wide and look at Yan Bugui, "Are you sleepy? I'm walking on the road, how do I know someone is looking for me?"

"You, you know it after hearing the news. This thing is amazing. If you want to find someone, just tell the number to the paging station, and then the other party will know that you are looking for him."

Chapter 406 Yu Li Has Vanity Too

Yan Bugui said, "I just heard the news about the principle of the pager. Although I don't understand it very well, that's probably what it means."

Liu Haizhong turned on his own radio, and sure enough, as long as he turned it on, he could receive He Yuzhu's news at any time.

After Liu Haizhong and Yan Bugui finished listening, Liu Haizhong stopped talking.
