Zhang Yifu raised his breath, stood up slowly, and tried to control his stage fright. Langran said: "Thank you for giving me the opportunity to speak. I have only been working for two months. I still need to learn and understand the overall equipment, production and safety situation in the system. I only have a few ideas about the automation monitoring system of Jiutan Power Plant. I will report to you leaders here-"

As he said, he picked up the analysis materials in his hand: "After all, I have limited understanding and have never been to the site. Judging from the materials alone, it is obvious that as the leaders and experts said, this is an accident caused by a system vulnerability. In the solution, the experts also gave a complete solution. As for automation technology, I personally think that there is actually a more intuitive and convenient solution in terms of software."

"Take the automation system of Jiutan Power Plant as an example, it is mainly divided into three modules. One is the distribution control system DCS, which is used to collect underlying information, such as boiler temperature, current voltage, etc.; the second is the power plant monitoring system SIS, which analyzes, optimizes and operates after obtaining the DCS data; the third is MIS, which is a management information system, which focuses more on enterprise management and process control. So now, when we return to the Jiutan Power Plant, the direct cause is that there are loops between the MIS system and the SIS system, and a large amount of useless data is sent and accumulated in a loop, causing the SIS system to crash."

When Zhang Yifu said this, he deliberately slowed down his speech, wanting to see if everyone understood.

Judging from the expression, some people seem to understand, but most people still nodded reluctantly. Maybe they can't figure out what these three modules are, but it's enough to figure out that there are these three modules.

This is the difference between Zhang Yifu and Hua Changqing. When facing different people, he will use different narrative methods to ensure that the other party can understand what he says is not a little slow. Otherwise, he will finish his own words. Not only will the matter not be settled, but he will still be resentful of "arrogant and aloof"

"Because I don't know what is the specific reason, it causes the circuit blockage between the systems, but this is not important. What is important is that we can use a very intuitive way to prevent such problems in the future."

Zhang Yifu raised his breath slightly: "Firewall."

Yes, it is a firewall, a security method that everyone uses from the National Security Bureau to small Internet cafes in county towns. It has not yet been popularized in this era and is an information security method of cutting-edge technology.

Looking at the puzzled expressions of everyone, Zhang Yifu had to explain in depth: "Simply put, a firewall is an information filter. When he finds that there is illegal data or abnormal data appears in large quantities and is congested, it will automatically play a role, temporarily blocking the data flow and calling an alarm. Circuits like this accident will undoubtedly be discovered and blocked by the firewall, and reminding the operation and maintenance personnel to deal with it as soon as possible. In addition, if the network attack that Mr. Zou just said really occurs, the firewall can also effectively block and protect. It can be said that setting up a firewall can not only eliminate internal troubles, but also block external defense lines and effectively ensure safe production."

No matter how much I said before, whether everyone understood it or not, in short, the last four words fell on production safety. Zhang Yifu's argument immediately put on a golden vest and invisibly rose to a strategic height.

However, in this era when computers are not even popular and the network is still backward, the concept of firewall is too advanced, so it is so advanced that no one present knows how to communicate with Zhang Yifu and how to echo him.

"Firewall...Firewall..." Mu Zhiheng muttered in a low voice, "What is the English pronunciation?"

As soon as he said that, he felt that it was inappropriate. How could an ordinary undergraduate student from the Northern Electrical Institute be so professional? If he had a doctorate, he might be able to answer one or two, but for a newly graduated undergraduate student, it was too difficult. Let's ask Hua Changqing.

But Zhang Yifu waited for a long time and immediately answered with the standard London accent that he had practiced for a long time.

“Firewall.”

Mu Zhiheng was stunned and slapped his palms and said, "I remembered that at this year's International Power Grid Conference, the US mentioned this concept. Yes, it is Firewall, firewall, firewall, firewall. Why didn't I think of it before?"

When the rest of the people saw that the boss affirmed this concept, they were sure that Zhang Yifu was not rude. They couldn't help but look at the undergraduate student with exaggerated expressions. This guy was so evil that he even knew the idea that the American had just proposed. Could it be that he had returned from studying abroad?

The outgoing of the firewall concept even touched Hua Changqing. He immediately pulled out of his confused mood and asked curiously: "Mr. Zhang, this concept is very new in the United States. What channel did you know?"

"Our college professor occasionally mentioned it. I was very interested. Later, I pestered him to ask for some foreign language materials. I studied it for a long time and thought it was a trend. After reading the accident report in Jiutan, I thought it would be a solution to the problem."

"Well..." Hua Changqing nodded, and then pulled the concept of firewall out of the corner of memory.

It’s not that he is short-sighted or ignorant, but at this moment, the firewall is too new, too small, and too remote. In China, even gods would never have thought it could be used in the control system in the power plant.

After thinking for a moment, Hua Changqing raised his cheek and raised his glasses and said seriously: "This proposal is very constructive. I suggest that we negotiate with the US side immediately after the meeting to see if we can provide relevant technical support."

The others were stunned again. Hua Changqing, who ignored him and looked down on all the engineers in China, was so sure of the remarks of a young technician?

I don’t know if the world is in chaos or if this little technician is really a god.

Although Lao Zou didn't understand most things, he figured out one thing, and the firewall was still imported from the United States. He immediately grabbed the appropriate argument and waved his arms and said, "The American firewall? After all, it's the United States. So what if it's done such a thing? If the United States wants..."

At this time, Hua Changqing rejected his debate in an unreasonable way. He raised his hand slightly and said in a not very strong tone: "Please shut up first, it's a technical discussion now."

The audience was ashamed, and Lao Zou was stunned.

Hua Changqing then turned to Zhang Yifu and asked: "As far as I know, even in the United States, firewalls have not been widely used in power systems. It is a network security technology. Do you think it can be easily applied in Jiutan Power Plant?"

"Yes, there are professional firewall manufacturers in the United States now, and they only need a machine box hardware to connect to the computer room. Maybe our software provider Bailey cannot provide a firewall, but we can ask them to seek a firewall company to do this."

"For example...Cisco?" Hua Changqing asked immediately.

"Or SonicWALL, as far as I know, there are only these two companies that provide hardware firewalls for the time being."

Hua Changqing showed an incredible expression. This little guy seemed to know more than himself.

—————————————————————

In the new week, the market is being pushed forward, which means it will be launched on January 1st.

Listing it on the shelves means a responsibility for me, because from that second, everyone has to pay to read books. There is no longer a mere appreciation and playful attitude between us, but a contract, a relationship between giving and giving.

Just like a marriage certificate, it is a responsibility that lasts forever.

Many friends have mentioned before that I have mentioned the problems of my previous bad deeds and TJ failures. I do not deny the taboos. Whether I say or not, I will put them in front of me and on paper. It is indelible. If I want to destroy these bad deeds, I can change my pseudonym and start over again. Anyway, "I've added mushrooms to you" is not very nice, right?

But I don’t have it. Both the good and the bad are placed on it, and it is clear at a glance, and it is neither evaded nor denied.

Books that are not on the shelves are like falling in love for me. If they are not suitable, they may give up, and if they are not good at the grades, they will give up. Yes, I have lived. But whenever a book is on the shelves, I will end up with one million words, without any water or drag, telling a story and telling an ending.

Of course, for most friends, they just like this book and don’t care about the past. In short, saying this is not a self-scrupulous or a bold statement, but I like this book very much, and I am sure I can continue writing it. I hope everyone can read it with confidence or fatten it. Sorry, the money for milk powder is on this. But at this time, my pleasure is far greater than the pressure, because this is a happy and simple story, an ordinary and ridiculous Zhang Yifu.

Here, please make a first order in advance! Please make a recommendation for the routine!

See you on January 1st!

Give you mushrooms!
Chapter completed!
