Often, this kind of troubleshooting work is carried out under the gaze of many people, and the pressure is very high for people who actually operate it. Bearing the expectations of others, or facing other people's doubts about your long-term inability to troubleshoot, is a kind of torture for people with low psychological quality. And the students in this team who are still educated in school and have not left the society are actually very testing under such pressure.

These students from Tsinghua University have actually been living in an ivory tower. They studied in the best universities in China and received the best education. Everywhere they went, they faced the envious gaze of others. As long as they show their student ID, they can get preferential treatment from others in most places. There are not many opportunities like today, because you didn't do a good job, and you face so many pairs of skeptical and critical eyes.

Therefore, what the old man Zhao Manhong is most afraid of is that the young people he is optimistic about will be intimidated because of such a scene. Although he has been in the military camp for many years, and what he has seen is the style of soldiers who face pressure without fear of criticism, but these young people have not officially entered the military camp, and Old Man Zhao naturally treats them to a different standard than those soldiers in his own army.

In fact, Old Man Zhao was too worried. You must know that these students are quite good students, and they have performed well along the way to study. And the process from elementary school to college is not necessarily smooth sailing. They have also experienced academic setbacks. It can be said that they are actually experienced in a hundred battles. If their ability to resist pressure is not strong, I am afraid they will not be able to go where they are today. So of course, Liu Yihao encountered pressure, and also felt the suspicious eyes around them, but they were not overwhelmed by such pressure, but turned this pressure into a motivation to promote their courage to solve problems.

Liu Yihao began to discuss the reasons for this failure with Wei Yuan, Liu Qian, and Yang Qiu. They want to rule out the possibility that the processing technology is not in place to cause such a difficulty. Although the barrel was somewhat modified during the modification of the machine gun, they repeatedly recalled this process. Wei Yuan can pat his chest and say that there is nothing wrong with his operation. And in this process, there is also the participation of Mr. Zhao Manhong. Mr. Zhao is an expert with a deep accumulation of firearms. With his participation and involvement, if there was any problem with the operation at that time, it would have been discovered at that time.

After Liu Yihao and Wei Yuan determined that there was no mechanical reason, he had an idea. Such a weapon with a certain amount of intelligence, in addition to the mechanical structure, since the introduction of automatic control, then the control logic is an important influencing factor. In such a situation, if there is no mechanical problem, is there a problem with the control part?

If that's the case, the problem is easier. Liu Yihao believes in his profession. Don't forget that you are from the Department of Electronics at Tsinghua University. If there is a problem with the control, that's the room for you to play. This is my main major. Thinking of this, Liu Yihao's interest couldn't help but rise.

"Liu Qian, and Yang Qiu. Now it seems that we are just going to have to take a good look at our control logic. Because Wei Yuan has already said, there will be no problems in our processing and manufacturing. Then as an auto-controlled machine gun, there is a great possibility that there is a problem with the control. You two are in charge of this, so let's see what the problem might be. ”

Liu Yihao didn't make a detour from Mr. Zhao Manhong this time, but directly discussed it with his friends. Indeed, when it comes to the problem of control logic, then it is actually possible to talk about it in isolation from the specific object. Control logic is an abstract thing, and there is not much difference between using it in a machine gun and using it in a microwave oven.

Liu Qian and Yang Qiu listened to Liu Yihao's question, and they were also thinking about it in their hearts. The two of them are the main responsible persons for electronics and controls in the team currently present. Now the leader of the project told them that there might be something wrong with their part of the work. In this case, the two of them have to check their original design to see if there is a problem.

To tell the truth, neither Yang Qiu nor Liu Qian really wanted to admit this kind of thing. Because you must know that this whole automatic control team was not designed out of thin air in the first place. On the contrary, they have also gone through several rounds of review and brainstorming. In such a situation, if there is no problem with the mechanical part, why should it be said that there is a problem with their work? This made Yang Qiu and Liu Qian not very convinced.

Of course, in this case, the gas blockage is useless. It's impossible to stiffen your neck and say why you say I have a problem, I can't have a problem. All Liu Qian and Yang Qiu could do was to take out their own design diagram and control logic diagram again, bury their heads together, and check and check little by little whether there were any hidden dangers left in the technical design part at that time.

Old man Zhao Manhong didn't squeak. In fact, after Liu Yihao ruled out the possibility that there was a problem with the mechanical part of the machine gun, he stopped commanding. Instead, he let Liu Yihao's instructions to his own team. This is because, first, although he was more familiar with weapons than these Tsinghua University students, most of the weapons of his time were not very intelligent. Those weapons that are purely manually operated require only mechanical knowledge, and there are not many requirements for electronic circuits. So that's right, in fact, Mr. Zhao doesn't know much about electronic control, and of course it's even more impossible to express any guiding opinions. Second, in fact, he also wants to see Liu Yihao's thinking and level when leading his team to solve unexpected problems. Since he intends to train Liu Yihao to take over his class, and lead some research work on light weapons in the future, of course, there are more relatively high requirements to measure Liu Yihao's ability. Of course, it was not his wish to have an accident that was suspected of being jammed with a machine gun, but being able to take advantage of this opportunity to check Liu Yihao's adaptability was also an opportunity for Old Man Zhao.

Probably the only person present who didn't have anything to do was Peng Weining. He is just a person who uses weapons, not the one who designs them. So in the face of these sudden failures, he really didn't have any ideas to solve the problem. Because he doesn't understand any control strategy or anything like that. All he could do was pin his hopes on the people who designed the fully automatic machine gun, watch them write and draw, and listen to their technical discussions. To be honest, he didn't understand it when he saw it, and he couldn't understand it when he heard it. At this moment, Peng Weining felt a sense of powerlessness. He couldn't help but think that if Shen Yiyi was here, she should be involved in the few boys who were now discussing, and discuss and explore the cause of the problem with them. It's just in this area, it seems that he will have no way to discuss it with Shen Yiyi in the future.

Liu Yihao: He did not participate in the discussion between Yang Qiu and Liu Qian. He had assigned this task to Yang Qiu and Liu Qian at that time, so now it was the responsibility of the two of them to tell themselves if there were any problems with the control and circuitry of the machine gun, and how to solve them if there were problems. If it was not at the test site now, but in the workshop at that time, Liu Yihao might still join the discussion between the two of them. But now here, due to space constraints, it is simply impossible for him to join those two people to discuss. So we can only hope for the ability of the two of them.

As for Wei Yuan and Zhan Hao, after they ruled out their own problems, because of the close relationship between Yang Qiu and Liu Qian, they could still hear the voices of those two people discussing, and if they glanced at it, they could also see the patterns of the two of them writing and drawing on paper. It's just that they didn't join the discussion between the two. Because at this time, gossip can only reduce work efficiency. What is needed now is to be able to solve the problem as soon as possible. After all, there are so many pairs of eyes staring at everyone around.

Yang Qiu and Liu Qian went back and forth, but they really couldn't see what was wrong with their design. They felt that they and their team's design was very comprehensive at that time, and that the design of the individual circuits and so on was reasonable. And there are even fewer problems that can arise during processing. So the control circuit should be nothing. After the two of them checked it a few times, they looked at each other and saw in each other's eyes that the results were similar to their own judgments. They thought that since both of them came to such a conclusion, they should be able to say it directly to Liu Yihao.

"We checked several times and found no problems with the design and manufacture of our automatic control parts. This problem should not be caused by the work on our side. Liu Qian said directly to Liu Yihao.

Yang Qiu, who was beside him, also strengthened his tone and said to Liu Yihao: "Yes." We both checked it and thought it shouldn't be our problem. ”

The conclusions of the two of them brought Liu Yihao a lot of trouble. He's the leader of the team, but he's also a great buddy to the brothers. He is very familiar with and understands the behavior of these brothers. If the two of them say that there is no problem, it means that the two of them really did not find the problem. Liu Yihao believes in the ethics of his brothers, and he will not admit it for the sake of face even though he has discovered the problem. In this case, there is really no problem with the control part?

However, is it a real problem that the machine gun malfunctions during firing? There are no problems, so why is there a breakdown? If something goes wrong, something must be wrong.

Liu Yihao asked his brothers: "If there is no problem with the mechanical part and no problem with the control part, then where will the problem occur?" There must be something wrong that causes the final machine gun to not fire. ”

Wei Yuan followed Liu Yihao's question at this time, of course, it is equivalent to a discussion with everyone: "There is no problem with control, there is no problem with machinery, then there is a problem with the connection between control and machinery." ”

Immediately, his reasoning was overturned by Zhan Hao on the side: "Impossible. The connection of the actuator is completed last. And it was also done by Zhao Manhong and Zhao Lao himself. So the actuation part can't be problematic. Do you remember that after we finished it, this part was tested specifically? The result of the test was that there were no problems. ”

Because he talked about himself, Mr. Zhao Manhong also joined in. He is also about to express his opinion: "Zhan Hao is right. I can be sure that there is nothing wrong with the mechanism of the actuation part. So now everyone has come to a conclusion, that is, there is no problem with the mechanical part, there is no problem with the actuation part, and there is no problem with the control part. So I ask you, what is the problem? ”

Old Man Zhao's words made these technicians a little confused, and of course a little embarrassed. Because there's a logical problem here. They looked through everything and came to the conclusion that there was nothing wrong with it. The problem is that these conclusions that are not problematic lead to a failure in the overall function. They can't justify that. But if there is a problem, they can't pinpoint what exactly went wrong. That's where they are in a quandary.

At this time, Peng Weining, who was idle on the side and just listened to these people muttering there, said jokingly: "Yes, in fact, there is no problem with the machine gun anywhere, but there is a problem with the application." Probably this pot should be carried by the application environment. ”

Peng Weining's words were said in a joking tone. That is, he and these people have been familiar with each other in the past few days, and they both know what each other looks like. Otherwise, people who are not familiar with it will think that Peng Weining is sarcastic about himself when they hear it.

It's just that Peng Weining's words, which were originally pure jokes, were heard in the ears of Old Man Zhao Manhong and Liu Yihao, but it seemed to be a holy light sprinkled on a place that was covered up and ignored by everyone before. Old Man Zhao and Liu Yihao glanced at each other, and the two said a sentence almost at the same time: "That's right!" It's a problem with the application environment! ”

Peng Weining couldn't help but be dumbfounded when he heard the words of the two.

No way? I was just joking, I just wanted to liven up the atmosphere, so I told a joke. Why do these two people seem to be serious at this time! (To be continued.) )
