Speaking of a topic with super profitability that can be developed by only a dozen people, Shen Yiyi suddenly thought of one. I think of the Chinese company that became popular more than a decade later, starting in Shenzhen, China, but capturing more than 40 percent of the U.S. market. Even above the White House, the Chinese brand that was illegally operated by White House employees and made the U.S. news, the iconic white body with three simple lines of "DJI". The company called "DJI" can be described as a model of makers. A mainland aberdeen and an aberdeen started from scratch and created the most growing cutting-edge company. The real reason is actually to launch that really forward-looking product at the right time.

Drones have gone beyond the military and found applications in the civilian sphere, and with a focus on aerial photography, they have enabled ordinary people to observe our world from a bird's-eye view from God's perspective. This is the blue ocean of the market that DJI has discovered. Shen Yiyi wanted to make such a drone, but it was a pity that the current technology and process let her know that it was not feasible.

Thinking about the current plastic manufacturing process, it is also very difficult to be able to make the kind of plastic on cheap mobile phones in later generations, and achieve that kind of finish. Neither the raw materials nor the processes have yet met that requirement. What's more, CMOS technology has not yet become widespread. Current optical-electrophotographic equipment is still very expensive. In such a situation, if the cost of an aerial drone alone is 50,000 yuan, and the clarity is not up to the level of film film, there must be no market. And even if there is a market, it must not be large.

Therefore, Shen Yiyi could only regrettably give up the aerial photography drone that was popular in later generations. Although she was very sure of the technical reserves in terms of flying machines.

So. How does Shen Yiyi, who has placed everyone's expectations, meet everyone's expectations?

Shen Yiyi really thought of a product that should be both money and meaningful: infrared automatic detection machine gun loading and firing system.

The name is still very high. If you say it, it also has a very eye-catching function. If a layman really wants to be confused, he wonders what the hell this is. In fact, take a closer look at this name and break down several nouns one by one, and you should be able to see the clues.

Shen Yiyi if he explained to the big guy. It should be said: "This is actually based on an ordinary 12.7mm heavy machine gun, and we have equipped it with an automatic refill system, an infrared detection system, a logic gate judgment circuit, and an automatic homing design module. ”

After listening to Shen Yiyi's words, those students roughly knew what the topic that Shen Yiyi imagined was. One by one, they all showed eager expressions to try. I'm afraid there aren't a few boys who don't like weapons. From Shen Yiyi's description, everyone can already think that this must be a weapon project.

Liu Yihao asked Shen Yiyi with some excitement: "Shen Yiyi, do you mean that our big task is to complete a machine gun that can fire automatically?" Do you think our current team can complete a project like this? ”

Shen Yi nodded: "It's not just automatic launching. I guess this machine gun should be able to automatically spot the enemy. And after aiming at the enemy, it will kill and damage the enemy in a large area with continuous fire. The reason why machine guns are used instead of rifles is that rifles can only form an ignition fire. And the machine gun can form surface fire, the killing surface is larger, and the lethality is also stronger. ”

"As for whether we can do it, I think we can. In fact, the project of this project is not very large. At present, the largest caliber heavy machine gun in China is 12.7mm. The machine gun's automatic refill system is actually not difficult. The automatic aiming system needs to have a mechanism for signal collection, judgment and execution. And these are closely related to our electronics department. For example, you need to control and judge the chip or something. Of course, enforcement is inseparable from the executive agency, but such a body is not complicated. And then it is more important that the results of our previous project can be used in this invention. Our infrared sensors can be used to find targets. And I think the most difficult part of this project is actually the infrared sensor. Without this obstacle, our school happens to have related topics for the next chip part, and it should be possible to produce samples now. You say, is it true that we can do this task? ”

A good topic leader must have the ability to deconstruct problems beyond others. In other words, she should be able to break down a complex thing into modules with relatively simple functions that can be realized, and then transform these modules into relatively easy development tasks. It's not hard to say that this job is not difficult. All that is needed is a clear logical idea, but unfortunately there are not many people who have such an idea.

Apparently. Shen Yiyi has such a clear idea. This kind of thinking is not something she only had after she was reborn, but it was really something she had in her previous life. A girl who wants to be an engineer, if her mind is a mess, she should not be able to finish her job a long time ago.

Liu Yihao asked Shen Yiyi: "What should I do with this machine gun or something?" Do you solve it or do you have to find the school to solve it? After all, our school is not a school of the Commission of Science and Technology or the military, is it difficult to make a connection? ”

Shen Yiyi said that everything has its own: "It's okay, you don't need the school to come forward." I'll figure out how to solve the problem of guns. You just have to focus on your respective areas. Liu Yihao: You will break down the part that we can undertake in a while, and consider letting the students claim the topics they are interested in or good at. ”

Liu Yihao nodded and said, "Don't worry." I'll do this. Just like when we designed the course, I would arrange the work. We do our part, you do what you do best. In this way, we will definitely be able to do a good job in this topic, and at the same time, we can also make our graduation thesis unique. ”

And after Shen Yiyi's explanation, the friends also found that this topic really has to be done. They thought that they might be able to touch the machine gun by passing this subject, and they were all excited. When I was in military training, I only touched a rifle, which was too enjoyable. Being able to touch the machine gun now doesn't make these boys "excited"?

Shen Yiyi no longer cared about how they distributed their respective course content. She had actually claimed two jobs herself. As a female engineer who studied mechanics in the past. In this class, which is mainly engaged in electronics, the part of the work that is related to the replenishment of ammunition and the execution of aiming is of course reserved for oneself. Because that's what I'm best at. But I'm also a student of electronics. Naturally, one should not write a mechanical paper. Shen Yiyi thought about it one by one, and it would be better for him to add a little automatic control chip to those mechanical actuators.

In fact, there is an intersection between the disciplines of the Department of Electronics and the Department of Automatic Control. In terms of solving specific problems, the basic core content of the two courses is similar when writing a thesis. However, automatic control is more focused on the design of program algorithms, while the Department of Electronics writes a paper to burn the software code of the automatic control system into a chip with similar functions. For general-purpose chips that are not powerful in this era, special chips that complete specific functions obviously have unique advantages in applicability and response speed.

As soon as Shen Yi thought of this, he felt that this time the Department of Electronics was really doing the right thing to do this project. If the problem is really completed in the future, there will really be a weapon with excellent performance. In later generations, everyone has experienced it when watching movies on the Internet. Those who play software choose hardware decoding, then the speed and quality must be better than software decoding, that's the reason. This is what the Department of Electronics is doing this time. It's really going to be a big news that makes people excitied!

Since the work he was assigned to was more complicated, Shen Yiyi also took out his own book and began to conceive and plan how to start his own research. Except, of course, for the content of your own dissertation. The mechanical actuator of the machine gun also has to be considered. It's just that this part is not in a hurry for the time being. Shen Yiyi thought that he would go home once on the weekend. Talk to your dad and find a machine gun to dismantle and see. You have to figure out the structure of the gun first, and then you can find a way to add a mechanism to it!

It should be said that these classmates who are with Shen Yiyi now are all those who have strong curiosity and competitiveness by nature. Of course, these people are also extremely curious. So, when they really have a research goal, they can really concentrate on it. And this class of students has been together since then. School life that moves the whole class even after school. This classroom has even become a special classroom for a class that is relatively rare in the university.

And it is precisely because of the current dormitory life that Shen Yiyi is a little troubled, so she usually drags it out in the classroom until the lights are about to go out. to reduce the chance of being treated coldly. This time, Shen Yiyi will definitely not find Qian Qian to join his team again. As for Sun Yunyun and Tian Hongxia, Shen Yiyi was going to wait for the later topics to progress to that point before considering whether to invite them to participate.

When I went home on Friday, it was Wang Kai who drove to school to pick up Shen Yiyi. Of course, Wang Kai still brought a passbook to school. A passbook with a password, Shen Yiyi and Qian Qian completed the transfer of her part of the rights. In front of Wang Kai, Qian Qian did not treat Shen Yi as thin as she did two days ago. Of course, Shen Yiyi would not show in front of Wang Kai that she had a conflict with this person.

But Wang Kai's sense of smell is still sensitive. In the car, while driving, he looked at Shen Yiyi in the rearview mirror.

"I think you seem to have a little bit of a problem with that Qian Qian this time? Why don't you two smile? It's very different from before. Wang Kai asked Shen Yiyi.

Shen Yiyi sighed "sigh" one by one: "Do you want to be so shrewd." I don't want to talk about it now, though. Anyway, in the matter of patent rights, we should have already done it. ”

Wang Kai saw that Shen Yiyi's conversation was not very interesting, so he wisely stopped spinning on this topic. His experience is that when Shen Yiyi doesn't want to talk about something, don't ask questions, otherwise it must be himself who is unlucky.

"Okay. But if you have a knot, it's better to find a way to untie it sooner. Otherwise, it might break out at some point and hurt you. Wang Kai was still kind enough to persuade him.

Shen Yiyi nodded and remained silent. The line in her heart is that it is easy to say, but it is not so easy to really do. Do you really think you are a spring, can you bend and stretch? The reaction force of the spring is very strong. If you are in a good mood, you will be ruthless, and you will be low and soft, and you will get along with Qian Qian. But I was very busy during this time, and I was a little tired after being hurt by the relationship between the mission when I was in the United States before, so I didn't have the leisure to mend any classmates in time for the time being. Let's talk about it when you have time or when you're in a better mood.

Wang Kai asked Shen Yiyi: "Are you still going to your grandparents today?" ”

Shen Yiyi suddenly remembered and said, "No." I'm not going today. I forgot to tell you when I got in the car, let's take me to my parents today. ”

"Parents? Military compound? Wang Kai asked.

"It's not. My parents are now helping me take care of the children in my grandfather's old house. Shen denied it one by one.

"With kids? What helps you with children? Wang Kai was startled at first, then thought of something, and suddenly asked: "Do you mean the child you brought back from Hong Kong?" ”

Shen Yi nodded: "Yes." He should have gone back there after middle school today. I'm going to see him too. It can't be that I brought people back and then left them all at my mom without caring at all. It's tiring to watch children, especially those who are menstruating. ”

Wang Kai listened to Shen Yiyi's words and laughed: "You! Are you twenty years old yourself? It's like you're a kid of this age. But I guess you mean you were very disobedient when you were in middle school? I'm curious how disobedient you are. ”

Shen Yiyi said secretly, Miss Ben is really older than you, but I won't say it. She didn't answer Wang Kai's words, because it seemed that she was about to get home.

It is not far from Tsinghua to Grandpa's old house. If you have a car, you can drive for a short time. Shen Yiyi asked Wang Kai not to open any more inside, and got out of the car a little distance from the door. Driving in and out, there was a little too much movement. She, a daughter who doesn't come often, doesn't want to be the reason why her parents are chewing their tongues here.

After closing the car door, she walked to the window and said to Wang Kai: "I'm here this weekend, and I won't go back to my grandfather." Take the bus to school on Monday by yourself. You don't have to pick me up. (To be continued.) )
