"Do I have it?" Chang Jiang panicked.

"All of you are here. "All the engineers involved in the project have. ”

Zhang Yifu was also in a hurry and used this trick.

Conservatively speaking, the small 10 million will be sent out like this.

But now there must be this kind of extreme stimulation, and at the same time keep each of them and avoid playing dirty at the critical moment, the man named Lu Wei is not a good man and a woman.

No matter how dirty you are, no matter how high Xu's salary is, can it be higher than a suite?

"I don't want a house, can I get cash?" Wu Bin, the head of the development team, was already about to blow up.

"It's too useless, you ......" Chang Jiang shook his head, and then asked, "Is it okay?"

"It's about 200,000 yuan, yes. ”

There is no way, not to suffer from widowhood and unevenness, it could have been only allowed to the people in the house, but when the people outside knew about this reward, they would inevitably be slack, and in the face of huge interests, bloodletting would also be bloodletting.

"Including the maintenance group, including people who are on a business trip. Zhang Yifu said to Shang Jin.

Shang Jin also panicked, he was already a little lost.

"This ...... Shaw ......" Chen Yanrui couldn't bear it anymore, "Do you want to keep it secret for the time being, so as not to ......?"

"I said confidentiality, can you hold it?" Zhang Yifu shook his head and said, "If the people on the production side have opinions, they have opinions, now is not the time to worry about this, the point is to win this bid." ”

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

DCS and the like are too general, in the practical application of research and development, from a functional point of view, the research and development components are divided into five aspects: data acquisition, protection, sequence control, continuous control and information management, which are almost all the functions of the thermal power plant automation system, and will remain the same in the next 20 years.

The concepts of data collection, protection, and information management are clear. Sequential control and continuous control may seem a bit more complicated, but it's also true, and that's where the real work comes in.

Sequential control refers to process control, including unit start and stop, boiler ignition, make-up water treatment, coal conveying system, etc., this part of the research and development needs to be logical and clear, otherwise the feed pump can not provide water. Once a stupid low-level mistake such as a crew starts and stops wrongly, it is basically equivalent to a self-destruct signboard.

Continuous control refers to the automatic closed-loop adjustment carried out during the operation of the unit, and the pressure, temperature, steam intake and other parameters are reasonably and automatically adjusted in the dynamic environment to ensure that the active and reactive power output issued by the unit is consistent with the dispatching instructions.

If sequential control must be strict and rigorous, continuous control requires sensitive response, fast execution, continuous adjustment in dynamic and random, and the pursuit of stability.

In the past, these were all done manually, and the master inspected and stared at the instrument to confirm the parameters. The watchman manually adjusts, there are many control equipment in the power plant, and it is running all year round, and the Jibei Power Plant needs thousands of workers to engage in production, and once the automation is completed, just like the Kashima Power Plant, people only need to guard the screen and judge the key abnormalities. 200 people are enough.

But how easy is it to make a system that can replace the work of thousands of people?

After a brief introduction. Summary: "At present, there is no need to consider the data collection, the ready-made simulation environment will have an interface to unify the simulation data of the conveyor unit. Protecting this piece is mature in principle, and we are a priority. Up to now, it has been basically formed, which depends on the previous experience of microcomputer line protection and the algorithm proposed by Mr. Zhang. In addition, in the area of information processing, the information given by Beimo is not too demanding. It is possible to display and record all aspects of the power station data at any time, and there is basically no difficulty. ”

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

"Yes. Chang Jiang nodded, "According to the idea you gave, all the control and operation are concentrated on a host to complete, so that although the conceptual design is simple, but too taken for granted, the amount of computing and data interaction is too large, not to mention the complexity of research and development, the hardware can not keep up, either the computing speed is slow, unstable, or it requires a lot of processors to cooperate, which involves more communication, and it is very difficult to implement." ”

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

"Actually, it's not completely overcome. Chang Jiang took off his glasses and sighed, "You see, we always say that what we are doing now is DCS, distributed control system, through a set of system to control many units scattered everywhere, it looks very simple, of course, simple is good, the simpler it is for users, the better, but we are research and development, we have to expand it, DCS is just a big concept, subdivided, including CCS, FSSS, DEH, SCS ......"

"Say Chinese......" Shang Jin listened loudly.

"To put it simply, it is a small ten systems such as boiler furnace control, steam turbine control, electrical control and so on. Changjiang Zhengse said, "Foreign manufacturers, not in one step, such as Siemens, is to make FSSS first, and then a little bit of expansion, development, cooperation, through more than ten years of efforts can sell a full set of DCS, pay attention, there are some modules, maybe used Hitachi." The so-called complete set of DCS that realizes the five major functions is combined through several modules, each module is independent, and the DCS only controls them as a whole. ”

Shang Jin was surprised and asked, "Then how many manufacturers are there with this full set of DCS supply capacity now?"

"If it's a full set, it's only two or three. Chang Jiang wiped his glasses and asked Zhang Yifu, "So let's be sure, do we want to make a full set? That is really a one-step step and directly reach the international first-class level." ”

No one spoke, although Chang Jiang said a beautiful vision, but it seems to be far away from everyone, digging coal, oil and steelmaking, this kind of physical work among the first-class can fight, this time it is completely computer technology, thermal control technology, communication technology.

"First of all, we are not in one step, what we need now is just one step to win the bid, and we have nearly three years to do it in the future. Zhang Yifu snapped his fingers and said, "In addition, I will not put forward such a ridiculous goal of reaching the world-class level in a few months, we just need to be a little stronger than Shenzi." ”

"Originally, we were more confident, but now it's a bit of a problem. Chen Yanrui sighed, "Originally, Shenzi, Kedian and we have their own strengths, Shenziqiang has mature related hardware products and experience in PLC and thermal control; Kedianqiang's hard power in research and development and Hua Changqing's unique understanding in communication, and foreign technical experience; we are strong in advanced algorithms, clear thinking, and experience in microcomputer protection." ”

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

"It's not good, there's already a finished product...... " Chang Jiang said with his cheeks back.

Shang Jin was puzzled: "PLC I know, it is a small microcomputer, logic controller, if you have to say, our microcomputer protection can be regarded as PLC after removing some functions." But why is there a finished product with PLC plus communication?"

"You see, what Mr. Zhang proposed is an all-in-one system, that is, a set of DCS to solve all problems. Chen Yanrui explained, "And the PLC is just the opposite, it is small and independent, you can install several PLCs in the furnace, do the logic algorithm separately, only control the furnace, and then install a few PLCs in the coal transportation area, and control the fuel separately." ”

"I see. After all, Shang Jin has studied for half his life, as long as he explains the concept clearly, he is easy to understand, not to mention that this explanation comes from the mouth of a university professor who is serious, "Shen Zi is equivalent to having a lot of such PLC products, but they are separate, basic automation, after the integration of science and electricity, it is likely that there is a way to create communication between them, that is to say...... The seven or eight modules you just mentioned, they almost have finished products that can be used?"

"It is an exaggeration to say that it is a finished product, but it still needs to be perfected, the disadvantage of PLC is that it is too small and too independent, and the communication interface is not unified, and it is difficult to unify, but if Shenzi or Hua Changqing has solved this problem......" Chen Yanrui looked at Zhang Yifu slightly, "In such a short time, it is difficult for us to catch up." ”

Zhang Yifu is actually also having a headache here, he deliberately revealed to Hua Changqing the network automation system, although it is the direction that the current network technology cannot reach, but Hua Changqing is not a fool, he will definitely be committed to solving this problem, rough, the design of the perfect communication channel in the stage is still within his reach. And 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's not so advanced?

Only use this channel technology to improve the splicing of the PLC, so that Shenzi only needs to do a small part of the DCS, and the rest is connected to the PLC. Although this workload and difficulty are very large, Bao Qi Hua Changqing has already helped them open the canal, just waiting for the water to arrive.

"Mr. Zhang, the company has come to this day, almost all of the ideas and ideas you put forward. Chen Yanrui said in a deep voice, "But this time, it is not as simple as a economizer or a microcomputer protection, and we have a clear and advanced competitor." ”

"I understand that there is a lack of consideration for Shenzi and Kedian. Zhang Yifu said.

But Lu Wei obviously thought about it, so he tried his best to collect the telegraph. Chang Jiang said on the side, "Actually, I just heard that there is a house in the bidding, and I was very excited, but now that it has slowly cooled down, I feel that it is really difficult, Mr. Zhang, I can guarantee that if I give me a few months, the transformer protection will definitely be able to come out, but the power plant automation ......"
