After the tour, on the way back to the hotel by car, Oda Choi came to Zhang Yifu again. As a senior professional salesperson, he could not miss any opportunity, whether it was fat or fly legs: "Director Zhang, are you interested in relay devices?"

Zhang Yifu thought about it and replied: "I don't have much interest in transistors. You can give a brief introduction to integrated circuits and microcomputer protection. ︾"

Oda Chee quickly smiled and said, "Director Zhang, you are an expert. I'm just showing off your skills. I believe you know one thing. The launch time of integrated circuit protection is quite embarrassing. Although it has its advantages, with the rise of microcomputer protection, it no longer has much room for survival."

"This is right, so have you basically given up on integrated circuits now?"

"It's not a question of giving up. The product is still being sold, but I'm not ready to invest more energy in research and development." Odaki said immediately, "Microcomputer protection is different. Most of the energy we have to protect professional and technical personnel is invested in this. As long as we can get enough trial opportunities, subsequent power grid resilience will be popularized."

“Is it difficult to win a trial opportunity?”

"On-site trial, after all, we have to strive for the cooperation of several major power companies, and our company also has to pay a lot." Oda Choe smiled awkwardly, "But please rest assured that our power plant microcomputer protection has completely entered the stage of popularization."

"I am more concerned about the algorithm mechanism and trial effects." Zhang Yifu said lightly.

"Director Zhang, what you said has exceeded my professional scope." Oda Kei said immediately, "But I can do my best to fight for it. I think so, I will contact the company's business department and do my best to provide you with a complete set of microcomputer protection introduction materials. You can take it back to China to learn more about it, or if you have time, we welcome you to bring a group to Japan for inspection at any time. How about it?"

After experiencing these two days, Oda Chee was in a daze and realized that Ou Wei was just eating and drinking, and he seemed to be the young man with courage.

"It's totally OK, thank you." Zhang Yifu shook hands with satisfaction. "The more detailed the information you provide, the more you can understand it."

"Pack it with me and I will definitely sort it out before returning to China." Oda Choi swears, "If you are interested, you can tell me as soon as possible. In addition, you have my business card. You can also contact me at any time after returning to China. If it is not convenient to contact me, it is OK to contact Mitsubishi's Beijing-based agency to convey it. I will cooperate with you with all my strength!"

Zhang Yifu nodded. He still has some good feelings for Oda Chee. As a professional salesperson, he is definitely qualified. Excluding nationality factors, if Hengdian Energy has such a sales team and trains a group of such people, he will definitely be the top team in China.

At this point, the main task to go to Japan was basically completed. The rest was to inspect the other two power plants, shop and play. Oda Kei accompanied him throughout the journey.

After inspection, Zhang Yifu took the time to visit several stores and finally completed the promise to Liu Jian.com. He spent a high price of RMB 4,800 to buy the Canon telephoto. Although it was spent on Liu Jian.com, Zhang Yifu still felt extremely painful when he took action. Photography is really something that ordinary people can do.

There is another thing that has made Zhang Yifu confused for a long time.

Although it was only 1991, [18x] patterns have appeared frequently in the corners of Tokyo streets. It is not uncommon to bring supercritical units and other things back. It is the most amazing thing to bring two AV videos of popular porn stars back. Recording hundreds of copies is enough for Zhang Yifu to become rich, but on the other hand, it is enough for him to be imprisoned.

Perhaps because Japan's economy is so good, everyone can work in large companies. The most popular ones at this moment are the secretary and ol themes. Zhang Yifu lowered his head and walked around. The empty, lonely and cold heart was very itchy. As for Wen Tianming, he didn't even dare to enter the store. He was afraid that he would be found out and would be arrested and entered the public security bureau when he returned to China.

Zhang Yifu thought for a long time, but finally gave up on buying. After all, he is in strict control now, because a videotape will delay major events.

...

Seven days later, when the airport was leaving, Oda Chee finally revealed his original intention to Zhang Yifu.

"Director Zhang, this is an urgent introduction to microcomputer protection materials." Oda Choi handed the two color page promotional materials and several copy papers to Zhang Yifu, "We are very sincere in cooperation."

"Thank you, I'll take it back and take a look first." Zhang Yifu was a little embarrassed, letting Oda Chee know that he was touching Mitsubishi's foundation and directly developing the next generation of products. He wasn't crazy? But he was not allowed to feel any self-blame and guilt. Isn't this the case for commercial competition? You join forces with Dongdian to rely on the foolishness of Ou Wei to trick us, right? This is the world of adults.

"In addition, I will say something more in my personal name." Oda Kei sighed immediately after sending the materials, "I believe that you, Zhang Yifu, have also understood Japan's economic situation in recent years?"

"If you know a little, you should also hold a lot of stocks, right?" Zhang Yifu teased.

"Of course, it's all our own from Mitsubishi." Oda Kei laughed and changed the subject, "But you don't know if you noticed that the yen exchange rate is in a rising stage. Orders of the same price may have to pay more in half a year for China. It is purely for your interests. Importing equipment should be done sooner rather than later."

"Oh? Are you so sure?" Zhang Yifu smiled.

"Director Zhang, Japan's economy will definitely continue to grow. In many industrial exports, Japanese products have completely surpassed American products. As we all know, Sony acquired Columbia Film and Television Company and Mitsubishi Heavy Industries acquired Rockefeller Center. These are just the tip of the iceberg. At this stage, our products still have a slight price advantage over Ge, but I'm not sure how long this will last."

"Yeah." Zhang Yifu smiled without saying a word. This passage of the girl was definitely carefully prepared, and the idiom was used quite well.

"Anyway, there is no other meaning. This is completely for your interests." Oda Kei looked down and looked at his watch. It was time to say goodbye, "I'll send it here and wish you a safe journey."

"Thanks."

Just as the two shook hands, Zhang Yifu noticed the large screen of the stock index, and a seemingly important news flashed through the lower part of the large screen. But Zhang Yifu couldn't understand it.

Because the Japanese stock market is so hot now, even the airport is equipped with large screens for stock indexes and information releases. Of course, this is the most primitive type. Although there are no pictures, it does not hinder information extraction.

The reason why Zhang Yifu noticed it was because there was a sensitive number in this news - 2%.3.25%.

Zhang Yifu pointed to the screen and asked, "What does that news mean?"

Odaki turned his head and read it silently, then narrowed his eyes slightly, and twitched his eyebrows: "The central bank's interest rate adjustment...is said it was a rumor, but it turned out to be true."

"From 2% to 3.25%?" Zhang Yifu asked.

"Yes."

“How many years has 2% been going on?”

"I can't remember it, it's been many years..." Oda Kei thought.

Zhang Yifu then patted Oda Chee and said, "I am very grateful for your arrangement of our itinerary and accept your personal advice. Finally, I will tell you in my personal name."

"Please say it." Oda Keikka said politely.

"Hurry up and sell the stocks, don't leave any penny left, and then come to China to invest."

"??" Oda Chee showed an indescribable expression of surprise. He did not believe that Zhang Yifu, who had always been so steady, would suddenly say such illogical words. It was simply unreasonable! Even though he paid great attention to etiquette, his expression at this time could not conceal his confusion and disdain, "Director Zhang, you are thinking too much. Everything about us is thriving. It is impossible for the 1.25% interest rate change to cause any impact."

"Look, this is the advice." Zhang Yifu finally smiled, "I may not listen to what you warned me. I will not necessarily listen. I will also be unable to understand what I warned you. Maybe the advice we give to the other party is correct, but our judgment is wrong?"

"No, I don't mean that."

In the bustling crowd, Zhang Yifu and Oda Chee shook hands last and turned around and embarked on the way back.

The history I thought I missed appeared when it was time for him to appear.

In this history, on the surface, the United States was the real winner, planning and cutting off everything, causing Japan to stagnate for ten or even twenty years, but the one who really rose was another young man in the United States.

The Koreans took advantage of this precious leisure to occupy the market that originally belonged to the Japanese until their confidence burst into unification of the entire universe.

I hope that this time, there will be a slight change, at least... in terms of microcomputer protection.

10 years is enough. The Chinese market is so big, at least in this regard, it should be better than the Kanzi?

On the return flight, Zhang Yifu closed his eyes and silently summarized the matters along the way.

Joe Oda said it well. As the yen appreciates, the price of doing business may change, but once the economic crisis breaks out, the position of both parties' subject and object will also change. When their confidence is destroyed, we will definitely have more capital and even introduce key technologies.

But that level is not what Zhang Yifu should consider. It is a national technical level. It is a group of professors from several institutes who need to sit together to conquer. As for what they should do, they should still report back to the country and look at the leader's intentions. Don't make any stance without authorization, and don't be induced by Ou Wei.

This is a business, you can only keep your troops in a stable manner, but you have to prepare for your private matters.

Zhang Yifu first looked at history and looked at the microcomputer protection process in our country in his previous life.

Surprisingly, in the previous life, there was a real elder brother in this regard. Even if I called the real elder brother, I would be a little disrespectful.

A knowledgeable man in his previous life brought back a complete set of microcomputers when he returned from studying abroad in the early 1980s and began to engage in research on microcomputer protection. He worked for 10 years. By the early 1990s, he could almost enter the popularization stage. Microcomputer protection inherited the long-established principles and technologies of simulation protection, as well as successful operation experience, fully utilized the advantages of intelligence, and brought a lot of convenience to the installation, testing and operation of the device, and was loved by the on-site staff. The veteran bet on all his assets and efforts on this, and it took him ten years to see it. Almost with his hands, he brought relay protection, which was originally lagging behind world-class for many years to the same level. It can even be said that the research and development and application of China's microcomputer protection was at the forefront of the world. With the joint efforts of that generation, using microcomputer protection as the starting point, it promoted the explosive development of my country's automation level and created a great cause.

In addition to admiration, Zhang Yifu also showed some uneasiness in his heart. The history of the 1980s and 1990s in the previous world is not exactly consistent with what happened in the 1980s and 1990s. Maybe the big old man in the present world will not appear and should create a miracle by himself. Maybe the big old man is just starting out and has not yet become a climate.

It’s not that I feel uneasy when I think of such an opponent, but that kind of real inexplicable guilt. If I take action on this aspect, I might have overcome the efforts of others for ten years.

Duan Youwei was sitting next to him, and Zhang Yifu immediately interrupted Duan Youwei in the book: "Mr. Duan, do you know who is working on microcomputer protection in China?"

"Microcomputer protection?" Duan Youwei waved his hand and smiled, "Microcomputers are not popular, so how can we talk about protection."

"Then have you heard of even the information that you are catching up on the wind and shadow?"

Seeing Zhang Yifu so serious, Duan Youwei frowned and thought hard, but shook his head: "I don't have any. You can ask Lao Chang, even if there is, he should do research in their school."

So Zhang Yifu woke up Chang Siping who was sleeping again.

"It seems that someone is doing it, but they are all slow and leisurely, without much substantial results." Chang Siping replied irritably and continued to fall asleep.

In this way, Zhang Yifu was undoubtedly much more relieved. No one was willing to do it. Besides, the market was so big that Hengdian could do it. Even if it did it, it would be impossible to not give others a way out.

It was boring during the flight, and he happened to use the next time to open the materials provided by Mitsubishi to see how their products were doing.

According to Zhang Yifu's existing knowledge, microcomputer protection can be roughly divided into three stages.

The first stage is the protection of microcomputer with single CPU operation and multi-plug-in combination. This stage is mainly an 8-bit microprocessor.

The second stage is to use multiple 8-bit CPUs to form protection, and there are fewer hardware circuits that need to be expanded, so that the bus cannot be plug-ins.

The third stage is to integrate protection functions into one chip to support more complex protection systems with more powerful and streamlined hardware.

This is the hardware stage, everything follows the hardware. Judging from Mitsubishi’s introduction, their equipment is in the middle of the second stage and is mainstream in the market.

But hardware is the final say in Silicon Valley. As a microcomputer protection manufacturer of different brands, the software part is still known.

The parameter input and parameter output are all set. The core depends on how the CPU is calculated and how it is calculated. This is the cleverness of the software system. It completely exceeds the computing power and logic capabilities of circuits and transistors. It can be designed and used by others. If the production of hardware depends on the industrial hard power, software design depends more on the genius of the human brain.

How to maximize the hardware capabilities and develop a software system with limited hardware computing speed and small storage space at this stage, with high speed, good and good hardware computing speed and high reliability, and how fast, good and safer software systems are naturally the top priority of subsequent "private affairs".

Back to the microcomputer protection itself, everything starts with the a/d conversion, that is, the mutual replacement of analog signals and digital signals, and converting parameters such as current and voltage into data input CPU. This is undoubtedly the first difficulty.

Well, another damn chip was used during this period. There is no doubt that this was made by Americans, so Odaki blew it for a long time, and their microcomputer protection devices were actually almost all the core of the United States.

Of course, the inner part of this chip can be fine-tuned, which is another profound knowledge, and it is also something that Zhang Yifu has no energy, ability and money to consider at this stage. He has temporarily written down the model of this analog digital conversion chip for subsequent research and development and cost calculations.

The following is the highlight, CPU and software system.

He has a lot of say in this regard, because this part basically has the same meaning as the computer host. Of course, this is not an ordinary office computer, but an industrial control-grade computer. An industrial control computer with a slightly lower standard of military products is generally higher than that of Zhongguancun.

The reason why industrial control machines are used is because the operating environment of power plants and substations and the harsh strong electromagnetic environment poses a great threat to the safe and reliable operation of microcomputer protection devices and has high anti-interference requirements.

But this is still not the most demanding place for technical requirements. The internal CPU and software system are the most interesting. Because this set of things is only for protection calculations, although the composition of hot is not much different from that of PC computers, it is not called PC, but digital filters. As a microcomputer protection manufacturer, the most important thing is just here. Those terrible algorithms, outrageous mathematical formulas, and the time setting of milliseconds are all here. This is the real technical core of microcomputer protection. The reason why a microcomputer protection device can have a profit of dozens of times higher than a PC computer.

At this point, Zhang Yifu could only laugh, and after laughing, he cried.

Xiaoshi Xiao’s algorithms are clear at a glance, and they don’t even need to verify them. The reliability has been completely tested. And depending on the times and hardware, Zhang Yifu can provide more than a dozen or dozens of versions in one breath, covering everything from transformers to large power grids.

Crying is a terrible formula, and it makes your scalp numb when you look at it, let alone write them down.

At this point, he developed more admiration for his predecessors. He was already scared of taking advantage of such opportunities, not to mention that his predecessors made a calculation by stroke by stroke.
