"Do I have it?" Chang Jiang was panicked.

"There are all those who are sitting there." Zhang Yifu gestured, "All the engineers involved in the project have."

Zhang Yifu was also impatient and used this trick.

Conservatively speaking, a small 10 million was given out.

But now there must be such extreme stimulation, and at the same time, keep each of them to avoid being dirty at critical moments. The man named Lu Wei is not a good man and a trustworthy woman.

No matter how dirty you are, how high your salary is, how high it is, how high it is to be higher than a house?

"I don't have a room, can I get cash?" Wu Bin, the development team leader, was about to explode.

"It's so unpromising, you..." Chang Jiang shook his head and then asked, "Is that OK?"

"It's probably about 200,000 yuan, it's OK."

There is no way, we should not worry about being weak but not being equal. We could only give it to the people in the house, but when people outside know this reward, they will inevitably be jealous and slack. In the face of huge benefits, bloodletting must be bleed.

"Including the maintenance team, including those on business trips," Zhang Yifu said to Shang Jin.

Shang Jin was also panicked. He was already a little lost.

"This...shelf..." Chen Yanrui couldn't help it, "Do you keep it a secret for the time being so as not to..."

"I said keep it confidential, can everyone hold it back?" Zhang Yifu shook his head, "If the people on the production side have opinions, they have opinions. Now is not the time to worry about this. The key is to win this bid."

When it comes to winning the bid, trouble comes again, Chang Jiang began to sort out the current situation.

The statements like ds are too general. In practical application research and development, from a functional perspective, the research and development component is divided into five aspects: data collection, protection, sequential control, continuous control and information management. These five aspects are almost the entire function of the thermal power plant automation system, and it will still be the case in the next twenty years.

The concepts of data collection, protection, and information management are all very clear. Sequential control and continuous control seem more complicated, and the facts are the same. The real kung fu is here.

Sequential control refers to process control. It includes unit start and stop, boiler ignition, water supply treatment, coal transportation system, etc. The research and development of this part requires rigorous logic and clearness. Otherwise, the water supply pump cannot supply water, and the unit error start and stop, such stupid and low-level mistakes, will basically be equivalent to self-destruction of the signboard.

Continuous control refers to automatic closed-loop adjustment during unit operation, and reasonably and automatically adjusts parameters such as pressure, temperature, steam inlet volume and other parameters in a dynamic environment to ensure that the active and reactive power output issued by the unit is consistent with the dispatching command.

If the order control must be strict and strict, continuous control requires sensitive response, fast execution speed, and continuous adjustment in dynamics and randomness. The pursuit of stability.

In the past, these were done manually. The master inspectors stared at the instrument to confirm the parameters, the duty officer adjusted manually, there were many control equipment in the power plant, and it was operated all year round. The Jibei Power Plant only needed thousands of workers to carry out production. Once the automation thing was completed, just like the Kashima Power Plant, people only needed to guard the screen and judge the key abnormalities. 200 people were enough.

But how easy is it to build a system that can replace thousands of people's work?

After brief introduction, Chang Jiang concluded: "The data collection area is not necessary to consider at present. In the ready-made simulation environment, there will be an interface to convey the unit simulation data. The principle of protection is mature, so we give priority to it. So far, it has basically taken shape. This depends on previous experience in microcomputer line protection and the algorithm proposed by Mr. Zhang. In addition, in the information processing area, there is no high requirement in the information given by Beimo. It can be displayed at any time and recorded all aspects of the power station data. It is basically not difficult."

"To put it bluntly, the difficulty lies in the two controls now, right?" Zhang Yifu asked.

"Yes." Chang Jiang nodded. "According to the idea you gave, all controls and operations are concentrated on one host. Although this concept design is simple, it is too natural. The amount of computing and data interaction is too large. Not only is the R&D complex, the hardware cannot keep up. Either the computing speed is slow and unstable; or it requires many processors to cooperate, which involves more communication and is very difficult to implement."

"How can foreign products overcome this?" Shang Jin asked.

"In fact, it was not completely overcome." Chang Jiang took off his glasses and sighed, "Look, we always say that what we are doing now is a DS, a decentralized control system, and controls many units scattered everywhere through a system. It looks quite simple. Of course, it is simple and good. The simpler it is for users, the simpler it is better. But we are developing it. To expand it, ds is just a big concept, and we will subdivide it down, including s, sss, deh, ss..."

"Speak Chinese..." Shang Jin was overwhelmed.

"Simply put, it is boiler furnace control, steam turbine control, electrical control and other small systems." Chang Jiang said seriously, "Foreign manufacturers are not in one step. For example, Siemens first makes SSS, and then expands, develops, and cooperates little by little. Only through more than ten years of hard work can the full set of DS be sold. You should note that some modules here may be used by Hitachi. Do you understand? The so-called complete set of DS that implements the five major functions are combined through several modules. Each module is independent, and DS only controls them as a whole."

Shang Jin asked in surprise: "How many manufacturers have the full set of DS supply capabilities now?"

"If you have a full set, there will be only two or three." Chang Jiang wiped his glasses and asked Zhang Yifu, "So we are sure to do a full set? That's really a step-by-step, and it's directly reaching the world-class level."

No one said that although Chang Jiang had a beautiful vision, he seemed to be far away from everyone. The physical work of mining coal, oil and steelmaking was among the best, so he could compete with it. This time, he was completely engaged in computer technology, thermal control technology, and communication technology.

"First of all, we are not in one step. All we need is to win the bid in one step. There will be nearly three years to do it in the next two years." Zhang Yifu spread his finger and said, "In addition, I will not propose such a ridiculous goal of reaching the world-class level within a few months. We only need to be stronger than Shen Zi."

"In the beginning, we were quite confident, but now it's a little troublesome." Chen Yanrui sighed, "Shen, KeDian and us have their own strengths. Shen Ziqiang has mature related hardware products and experience in thermal control. KeDian's hard power in R&D is combined with Hua Changqing's unique understanding of communications and technical experience abroad; we are strong in advanced algorithms, clear ideas, and experience in microcomputer protection."

"But now, the two sides are integrated." Chen Yanrui slapped his palms, "Mr. Zhang, you can simply imagine the excellent and mature pl and advanced communication technology."

"Maybe, there is already a finished product..." Chang Jiang said with his cheek on his back.

Shang Jin said inexplicably: "I know that it is just a small microcomputer, a logic controller. If we have to say something, our microcomputer protection can also be considered pl. But why does pl add communications have finished products?"

"You see, Mr. Zhang proposed a system that integrates one system, that is, a set of DS solves all problems." Chen Yanrui explained, "and the pl is the opposite, small and independent. You can install a few pls in the furnace, do a separate logic algorithm, only control the furnace, and then install a few pls in the coal transport to control the fuel separately."

"I understand." After all, Shang Jin has been studying for half his life. As long as he explains the concept clearly, it is easy for him to understand, not to mention that this explanation comes from the veritable university professor. "Shen has many such pl products, but they are separate, basic automation and integration of Kepin, and there is a way to create communication between them. That is to say... the seven or eight modules you just mentioned, they have almost finished products to use?"

"It's an exaggeration to say that it's a finished product, but it still needs to be perfected. The disadvantage of pl is that it's too small and too unique, and the communication interface is not unified, so it's difficult to unify. But if Shen Zi or Hua Changqing have solved this problem..." Chen Yanrui looked at Zhang Yifu slightly, "It's hard for us to catch up in such a short time."

Zhang Yifu was actually having a headache. He deliberately revealed to Hua Changqing that the network automation system was a direction that network technology could not reach now, but Hua Changqing was not a fool. He would definitely work hard to solve this problem. It was a bit rough and he could only improve the ultimate communication channel at the stage of designing the design. The reason why Zhang Yifu dared to provide this idea to Hua Changqing was that he knew that even the ultimate channel at this stage was still a drop in the bucket and it was impossible to complete the advanced concept of that set of automation devices.

But what if it is not so advanced?

Only use this channel technology to improve the splicing of the PL. In this way, Shen only needs to do a small part of the SL and connect the remaining PL. Although the workload and work difficulty are very high, Hua Changqing has already helped them open the channel and wait for the water to arrive.

"Mr. Zhang, the company has been able to reach today, almost all the ideas and ideas you put forward." Chen Yanrui said in a deep voice, "But this time, it is not as simple as a protection of an economizer or a microcomputer, and we have a clear and advanced approach to our competitors."

"I understand that I lacked consideration for Shen Zihe KeDian." Zhang Yifu said with his chin on his back.
