691 Unconditional trust
"There is such a large span??" Jia Luansong asked in surprise, "No matter how you look at it, the concept of ECMS is not as exaggerated as a time machine, right?"
"I'm exaggerating to say that...... Let's just say that the world's top electrical manufacturers, together with the world's top software vendors, may not be able to do this so-called ECMS. ”
"It's easier to understand ...... like this," Jia Luansong smiled with a sigh of relief, "What are you anxious about, what you said is 'not necessarily done', not 'must not be able to do', right?"
"The problem is that a bunch of geniuses from Silicon Valley are doing it, should we find a group of Zhongguancun people who sell pirated disks?"
Jia Luansong smiled dumbly.
Hu Haitao suddenly lost his words: "I'm sorry...... I'm a little anxious...... Zhang Yifu should do it honestly, it is really eye-catching, but it is almost equivalent to giving up automatically. ”
Jia Luansong squinted his eyes and looked at the experts around him: "They are looking very seriously, they haven't felt ridiculous for the time being, right?"
"That's because they don't understand our technical background. Hu Haitao still shook his head, "Zhang Yifu is inflated, it's too imaginative...... It's just a breakthrough in the small specialty of traveling wave computing...... He felt that nothing could stop him. ”
"Dean Hu, how long have you known Zhang Yifu?"
"More than a month?"
"I've known each other for a few years. Jia Luansong smiled gently, "He won't fool around, let alone gamble so much money, energy and trust at such an important time." ”
"Hey......" Hu Haitao no longer argued, in his eyes. It is because Jia Luansong does not have a deep understanding of this professional field that he has such blind self-confidence, after all, he is young. It is easy to be fooled by Zhang Yifu's limited achievements and personal charisma.
Just as he was about to understand more, he heard Larson next to him exclaim.
"This ......," Larson rubbed the slippery Celestial Spirit cover in surprise, "This will work!"
The audience was in an uproar.
Larson is undoubtedly a leading expert, how can he say this?
Larson raised his glasses and said seriously: "We all know that there are three difficulties in implementing ECMS, one is the network environment, and the other is the interface connection with DCS. The third is a powerful enough central system. There have been some international attempts to overcome these three points, but this requires a huge transformation on the existing basis, from wiring to structural changes. The results are unpredictable and profits uncertain, so few have made real changes. ”
"I support this statement. Thomas chimed in, "As a power plant manager." I understand the situation very well. The change is unknown, and what is in front of us is just enough to meet the application, plus the number of new large-scale thermal power plants in developed countries is very small, so a lot of things about ECMS are still in the theoretical research stage, and have not really been put into practice. ”
That makes sense, but it still doesn't overturn the three contradictions that Mr. Larson said. "First of all, the network environment, or communication technology. In the case of ECMS, everything will be collected and controlled through the power plant network. The huge amount of electrical power will also be involved in the DCS system and included in the calculation, not to mention whether the communication environment can be kept smooth, but the response speed alone, I am afraid it is difficult to guarantee, and it is not necessarily more optimized than the DPU. ”
Bill, a Canadian expert who is relatively supportive of Shenzi (Mitsubishi)'s conservative line, grabbed a handful of thick brown hair and echoed: "Yes, the data needs to be transmitted into the DCS, calculated, given the results, and then fed back to the electrical equipment. ”
"Haven't you seen the rest of the story?" Schroeder coughed, "Look at page 14, Hengdian has given a clear solution for the communication method, the complete system, which will use fieldbus technology." ”
Everyone hurriedly turned to this page, some in thought, others in a daze.
Fieldbus technology (FCS), which sounds so lofty, actually has a more straightforward explanation - networking, to take a little deeper, that is, in the entire power plant, to form a unified and standardized network environment, most of which are Ethernet.
To be more direct, Internet café wiring, which can also be called fieldbus technology, is much simpler than industrial buses.
The reason why it sounds so lofty now is simply because the application of Ethernet is limited and the relevant standards are not mature enough. It is worth mentioning that, in industrial automation, including in the field of power generation, its mainstream communication mode is still analog signal, usually one-to-one and single-loop, poor anti-interference ability, accuracy and stability will also be affected by the signal, such an automation system based on analog signals, compared with the system based on fieldbus technology, this gap can be understood as a TV directly plugged into the TV line, and the gap between watching digital TV through the set-top box, the clarity of the two, the amount of information, and the interactivity are not the same.
However, limited by the popularity of Ethernet and the chaotic standard situation, the application of fieldbus technology is limited, in the current power plant automation pattern, most of them still use analog signals to get it, occasionally there are some relatively small ranges, experimental use of digital signals in the place, the practical effect is general, this analog and digital mixing mode has caused an unstable situation, there will be some people to compare this situation with the simple analog signal situation, and the blame is pushed to the fieldbus, not as stable as the traditional way.
This time, Hengdian proposed a complete fieldbus technology, except for the backup, the key places that need hard wiring, all based on industrial Ethernet bus technology, almost ten years earlier, put forward the digitalization of the whole plant.
Bill chuckled and put down the material: "We can't say anything, we think he can accomplish something, right?
Another chimed in: "It's probably no harder than a full-fledged fieldbus." ”
"Haha. Several people laughed.
"Wait, gentlemen, read the instructions carefully. Schroeder is still the same old pedantic, "Hengdian will use the PROFIBUS fieldbus standard, the stability and practicability of PROFIBUS has been certified by our IEC, is an international general standard, I don't think this standard can not meet the needs of Beimo." ”
"Of course, that's the standard that you Siemens put forward and mainly wrote. Bill then laughed, "You must be more than happy to see the standards promoted by Siemens in the explanation, and I understand that." (To be continued......)
