At the end of the visit, on the way back to the hotel by car, Oda Kirishige came to Zhang Yifu's side again, as a senior professional salesperson, he could not let go of any opportunity, whether it was fat or fly legs: "Director Zhang, are you interested in the relay device?"

Zhang Yifu thought for a while and replied: "I don't have much interest in transistors, you can give a general introduction to integrated circuits and microcomputer protection." ”

Xiao Tian Che hurriedly smiled and said: "Director Zhang, you are an expert, I introduced it is the class to get the axe, I believe one thing you also know, the advent time of integrated circuit protection is more embarrassing, although it has its advantages, but with the rise of microcomputer protection, it has little room to survive." ”

"That's right, so you've basically given up on integrated circuits now?"

"It's not okay to give up, the product is still selling, but I'm not ready to invest more energy in research and development. Oda Che then said, "Microcomputer protection is different, most of our protection professional and technical personnel are invested in this, as long as we can win enough trial opportunities, the follow-up power grid relay will be popular." ”

"Is it hard to get a trial opportunity?"

"On-site trial, after all, we have to win the cooperation of several major power companies, and our company also has to pay a lot. Oda Kiri smiled awkwardly, "But don't worry, our power plant microcomputer protection has completely entered the popularization stage." ”

"I'm more concerned about the algorithm mechanics and the effect of the trial. Zhang Yifu wrote lightly.

"Director Zhang, what you said has gone beyond my professional scope. Oda Kiri followed, "But I can fight for it as much as I can." I think so, I will contact the company's business department, do my best to provide you with a complete set of microcomputer protection introduction materials, you can take back to China to slowly understand, or if you have time. We always welcome you to bring another delegation to Japan, how about it?"

After experiencing the events of the past two days, Xiao Tian Che also realized in a trance that Ou Wei was eating and drinking, and it seemed to be this young man who had the courage to take the idea.

"Absolutely, thank you very much. Zhang Yifu shook hands with satisfaction. "The more detailed information you provide, the more you can understand on my side. ”

"Wrap it on me, and you must sort it out before you go home. Oda Kiri swore solemnly, "In other aspects, you can also inform me as soon as possible if you are interested, in addition, you have my business card, you can also contact me at any time after returning to China, if it is inconvenient to contact me, it is also possible to contact the Mitsubishi agency in Beijing to convey it, and I will fully cooperate with this side!"

Zhang Yifu nodded. He still has some good feelings about Xiao Tian Che, as a professional salesman, he is absolutely qualified, excluding the factor of nationality, if Hengdian can have such a sales team and cultivate a group of such people, it is definitely the top team in China.

So far, the main task of going to Japan has been basically completed. All that's left is to visit the other two power plants and shop and play. Oda Kiri accompanied the whole process.

After the inspection, Zhang Yifu took time to visit a few stores, and finally completed the promise to Liu Jianwang, and spent a high price equivalent to 4,800 yuan to buy a Canon large telephoto. Photography is really not something that mortals can do.

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

Although it's only 91 years, in the corners of the streets of Tokyo, the pattern of [18X] has appeared frequently, and it is not uncommon to bring back a supercritical unit or something, and it should be the most shocking thing to bring back two AV videos of popular stars. Recording a few hundred copies is enough for Zhang Yifu to make a fortune, but on the other hand, it is enough for him to go to prison.

Maybe it's because the Japanese economy is too good, everyone can work in a big company, the most popular at this time is the secretary and OL theme, Zhang Yifu lowered his head and walked around, the empty, lonely and cold heart was itchy and unbearable, as for Wen Tianming, he didn't even dare to enter the store, he was afraid that he would be known, and he would be arrested and put into the public security bureau when he returned to China.

Zhang Yifu thought about it for a long time, and finally gave up the purchase, after all, it is now strictly controlled, because it is not good for a videotape to delay a big event.

……

Seven days later, when the airport was parting, Oda finally confided in Zhang Yifu.

"Director Zhang, this is an urgent introduction to microcomputer protection. Oda Kiri handed Zhang Yifu two color leaflets of promotional materials and a few copies of paper, "We are very sincere in our cooperation. ”

"Thanks, I'll take it back and see it first. Zhang Yifu is a little embarrassed, let Oda Che know that he is touching the bottom of Mitsubishi and directly developing the next generation of products, he is not crazy? But he is not allowed to have any self-blame and guilt, isn't this the case with commercial competition? You must not have felt guilty when you teamed up with TEPCO to fool Ou Wei to pit us, right? This is the world of adults.

"Also, I would like to say one more thing on a personal note. After Oda Kiri, he sighed, "Japan's economic situation in recent years, you must have known something, right?"

"If you know a little bit about it, you should also own a lot of stocks, right?" Zhang Yifu teased.

"Hold, of course, it's all our Mitsubishi's. Xiao Tian Che laughed, and changed the conversation, "But there is one thing I don't know if you have noticed, the yen exchange rate is in a rising stage, the same price of the list, maybe in another half a year, for the Chinese side will have to pay more, purely for your interests, the matter of importing equipment, it is better to import equipment sooner rather than later." ”

"Oh, are you so sure?" said Zhang Yifu with a smile.

"Director Zhang, Japan's economy will definitely continue to grow, in a number of industrial exports, Japanese products have completely caught up with American products, as we all know, Sony acquired Columbia Pictures Company, 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 am not sure how long this can last. ”

"Hmm. Zhang Yifu smiled and said nothing, this girl's words are definitely carefully prepared, and the idiom is quite slippery.

"In short, there is no other meaning, it is entirely in your own interest. Oda Kiri looked down at his watch, it was time to say goodbye, "I'll send it here, I wish you a safe journey." ”

"Thank you. ”

Just as the two were shaking hands, Zhang Yifu noticed the large screen of the stock index, and a seemingly important news item was crossed at the bottom of the large screen. It's just that Zhang Yifu can't understand it.

Because the Japanese stock market is so hot now, even the airport is equipped with a large screen for stock index and information announcement, of course, this is the most primitive kind, although there are no pictures, but it does not hinder the ingestion of information.

The reason why Zhang Yifu noticed it was because there was a sensitive figure in the news -- 2%. 3.25%。

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

Oda Kiri turned his head and read it silently, then squinted slightly, and his brows twitched: "The central bank's interest rate adjustment...... It was said to be a rumor, but it turned out to be true. ”

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

"Yes. ”

"How many years has 2% been going on?"

"I can't remember, it's been a long time......" Oda said thoughtfully.

Zhang Yifu then patted Xiao Tian and said, "I thank you for arranging our trip, and I also accept your personal advice, and finally I will tell you in my personal name." ”

"Speak. Oda said politely.

"Quickly dump the stocks, don't have any left, and then come to China to invest. ”

"??" Oda Kiri showed an indescribable look of surprise. He didn't believe that Zhang Yifu, who had always been so steady, would suddenly say such illogical words, which was simply unreasonable! Even though he paid considerable attention to etiquette, his expression at this time could not hide his incomprehension and disdain, "Director Zhang, you think too much, our Yiqiē is thriving, and it is impossible for the 1.25% interest rate change to have any impact." ”

"You see, that's the advice. Zhang Yifu finally smiled, "You warned me." I won't necessarily listen, I warn you as well. It's hard for you to understand, maybe we are all right in our advice to each other, but our own judgments are wrong?"

"No, no, I didn't mean that. ”

In the bustling crowd, Zhang Yifu shook hands with Oda Che for the last time, turned around and embarked on the way back.

History that I thought I had missed. Or when he should have appeared.

In this period of history, on the surface, the United States was the real winner, planning and cutting off a qiē that plunged Japan into a decade or even a decade or two of stagnation, but the real rise. But it's another little brother in the United States.

The Koreans took advantage of this precious time to aggressively encroach on the market that originally belonged to the Japanese, until their confidence exploded to unify the universe.

Hopefully, this time, there will be a slight change, at least ...... In terms of microcomputer protection.

10 years, it's enough, the Chinese market is so big, at least in this aspect, it should be stronger than a stick, right?

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

Odakiri is right when he says that with the appreciation of the yen, the price of doing business may change, but once the economic crisis breaks out, the host-guest positions of both sides will also change, and when their confidence is destroyed, we will definitely have more capital and even introduce key technologies.

But at that level, it is not what Zhang Yifu should consider, it is something at the national technical level, and a group of professors from several research institutes want to sit together to overcome it, as for what they should do, they still have to return to China to report and see what the leaders mean, don't take any position without authorization, and don't be induced by Ou Wei.

This is a public matter, and we can only do not move, but we must take precautions for private matters.

Zhang Yifu first looked at the history and looked at the process of microcomputer protection in China in the previous life.

Surprisingly, in my previous life, there was a real big brother in this regard, and it is a little disrespectful to call the real big brother, and it is right to call the elder.

In the early 80s, when the people of insight returned from studying abroad, they had already brought back a complete set of microcomputers and began to engage in research on microcomputer protection, which lasted for 10 years, and by the early 90s, it was almost possible to enter the popularization stage. Microcomputer protection inherits the mature principles and technologies of analog protection accumulated for a long time, as well as successful operation experience, and makes full use of the advantages of intelligence, which brings a lot of convenience to the installation, test and operation of the device, and is deeply liked by on-site staff. The old man will be a piece of his own assets and hard work on this, a glimpse is ten years, almost with the power of his hands, the original lagging behind the world's first-class relay protection, pulled to the same level, it can even be said that China's microcomputer protection research and development application in the forefront of the world, in the joint efforts of that generation, with microcomputer protection as the origin, to promote China's automation level has also produced explosive development, cast a great cause.

In addition to admiration, Zhang Yifu also showed some uneasiness in his heart. The history of the 80-90s of the last life. It is not exactly the same as what happened in the 80s and 90s in the current world, maybe the old man in the current world will not appear, and it is time to create a miracle by himself, maybe the old man is just starting out now, and he has not yet become a climate.

It's not that I'm uneasy at the thought of having such an opponent, but that kind of real inexplicable guilt. If you do this yourself, you may be able to overwhelm the hard work of others for ten years.

It happened that Duan Youwei was sitting next to him, and Zhang Yifu immediately interrupted Duan Youwei who was reading the book: "Mr. Duan, do you know who is engaged in 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 ever heard of the information that is afraid of chasing after the wind?"

Seeing that Zhang Yifu was so serious, Duan Youwei frowned and thought for a while, but still shook his head: "I don't have an impression." You can ask the old man, and 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 it is all slow and reasonable, and there is not much substantive results. Chang Siping replied irritably and continued to sleep.

In this way, Zhang Yifu is undoubtedly a lot more relieved, no one can do it, and the market is so big, Hengdian will do it. It is impossible to get to the point where you don't give others a way to live.

The flight was boring, and he used the rest of the time to open the materials provided by Mitsubishi. See how far their products have been.

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

The first stage is the microcomputer protection of single CPU operation and multi-plug-in combination, and this stage is mainly 8-bit microprocessors.

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 can not be plugged in.

The third stage is the integration of protection functions into a single chip. Powerful and streamlined hardware supports more complex protection systems.

Judging from Mitsubishi's introduction, their equipment is in the middle of the second stage and belongs to the mainstream of the market.

But there's such a thing as hardware. In the final analysis, Silicon Valley is what it says, and as a microcomputer protection manufacturer of different brands, it is still the software part that is clear.

Parameter input and parameter output are all the same, and the core still depends on how the CPU calculates and calculates. This is the brilliance of the software system, which completely exceeds the computing power and logic power of circuits and transistors, and is designed and exerted.

How to maximize the hardware capabilities and develop a software system with strong sensitivity, high reliability and high reliability under the current situation of limited hardware computing speed and small storage space has naturally become the top priority of the follow-up "private matter".

Returning to the microcomputer protection itself, starting from the A/D conversion, that is, the mutual exchange of analog signals and digital signals, converting parameters such as current and voltage into digital input to the CPU, which is undoubtedly the first difficulty.

Well, in the meantime, another damn chip will be used, there is no doubt that this is made by the Americans, so Oda Che blows for a long time, and in their microcomputer protection devices, in fact, almost all of them are the core of Lao Mei.

Of course, the intrinsic nature of this chip can be fine-tuned, which is another extremely deep knowledge, and it is also something that Zhang Yifu has no energy or money to consider at this stage. He temporarily wrote down the model of this analog-to-digital conversion chip for subsequent research and development and cost calculation.

Here's the play, CPU and software system.

Of course, this is not an ordinary office computer, but an industrial control computer, which is slightly lower than the military standard, and the cost is higher than that of a host in Zhongguancun.

The reason why the industrial computer is used is because of the operating environment of power plants and substations, and the harsh strong electromagnetic environment brings great threats to the safe and reliable operation of microcomputer protection devices, and the anti-interference requirements are high.

But this is still not the most demanding place of technical requirements, the internal CPU and software system is the most interesting, because this set of things is only used for protection computing, so although its composition is similar to the PC, it is not called PC, but called digital filter, as a microcomputer protection manufacturer, the most important thing is precisely here, those terrible algorithms, outrageous mathematical formulas, accurate to the millisecond time setting are here, this is the real technical core of microcomputer protection, the profit of a microcomputer protection equipment can be dozens of times higher than the PC。

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

Laughing at the laughter, these algorithms are unobstructed for him, and they don't even need to be checked, and the reliability has been completely tested by wind and rain, and according to the different times and hardware, Zhang Yifu can provide more than a dozen or dozens of versions in one go, covering everything from transformers to large power grids.

Crying is crying These equations are simply terrible, and it makes people's scalp tingle when they look at it, let alone write them down.

At this point, he had more admiration for his predecessors, and he was already frightened to be so opportunistic, not to mention the design of his predecessors one by one.

But rest assured, seniors, I am doing this to make Yiqiē better, to make the career move forward, and to make everyone's life better. (To be continued......)
