Tech house system

The time for the competition was approaching, and they couldn't study it slowly in a hurry. After discussing it, the three of them decided to seek guidance from Sun Yi's father, Professor Sun who worked in the school.

Wei Shuxun followed them with a toolbox in his arms, listening to Sun Yi and Liu Yongdong discuss the air interference in the signal transmission while walking, and asked Feng Wei: "Can I ask the professor for help?"

"Of course." Feng Wei nodded: "Many schools also have special organizations. From design ideas to formulas to design drawings, all professors and guidance are required. The only difference is doing it yourself. The students are just puppets. But A University doesn't like competitions of this level. , so it is voluntary for the students to participate. You can find a lot of interest groups participating in the school’s campus honor section.”

Wei Shuxun handed the toolbox to Feng Wei, and logged into the school forum with his mobile phone. Sure enough, he saw a lot of "Students participating in the National Undergraduate Electronic Design Competition join the group, let's encourage each other", "Students who need to major in automatic control and want to participate in the competition come to Sign up".A whole page down, most of these posts.

"There are so many people participating?" Wei Shuxun was surprised.

"Because there are no restrictions, there are a lot of people participating, so it's not certain how many people can pass." Feng Yu said, with pride on his face: "However, University A has always had the most students, accounting for half of all competition groups last year. That's why we rely on this competition to make Liu Yongdong look good."

Wei Shuxun has no sense of collective honor, and doesn't need competitions to become famous. He just nodded and took the toolbox back when he heard it. He couldn't help with technology, so he could only express it by selling his labor.

Sun Yi's father, Professor Sun Cheng, is an old man who is nearly fifty years old. He also wears a pair of thick black-rimmed glasses, and the corners of his mouth are slightly bent. He doesn't smile when he sees his son coming. He is a very serious person.

After hearing Sun Yi's narration, he said, "Give me your design."

After flipping through the design pictures, he said: "The idea was completely wrong at the beginning. Although the permanent magnet coupling can receive signals, the receiving distance is not far away, and it is easily interfered by the air. How can we do signal enhancement..."

While reprimanding, he continued to read.The four of them stood side by side in front of his desk, bowing their heads obediently to be scolded.Although he sternly lectured, the content was solid. Wei Shuxun didn't feel disgusted when he heard it, so he carefully wrote it down while listening.

After Professor Sun Cheng read the first design drawing, he began to read the second design drawing.This design drawing was revised overnight by Sun Yi and the other three. They haven't tested it yet, so they directly brought it to Professor Sun Cheng for advice.

Professor Sun Cheng looked at it for a while, then nodded: "This time it's about the same. The idea of ​​signal remote sensing is correct. But the signal is easy to be connected in series, so it should be replaced by signal stable remote sensing, adding an arch line static program. And then add a resolution sub-program ..."

As he spoke, he marked on the design drawing.

Wei Shuxun saw that he simply corrected the design information, and after he finished reading it, he couldn't help asking: "Professor Sun, do you already have the signal booster?"

If it's already on the market, they can't take it to the competition.

"Not yet." Professor Sun Cheng shook his head: "I haven't heard of it."

"Then how do you know the blueprint so clearly?"

"You can understand it at a glance." Professor Sun Cheng smiled slightly: "You will know when you are my age. The idea is good and practical, take it back."

Sun Yi took the design drawing and said happily, "Thank you, Dad."

The four were about to leave when the office door was pushed open, and an old man in his fifties with two gray manes walked in.Wearing a pair of rimless glasses, he was slightly chubby, and walked into the office in loose sportswear. He glanced at the four of Wei Shuxun and asked with a smile, "Professor Sun, are you busy?"

"Professor Zhao, are you back?" Professor Sun Cheng stood up and asked respectfully, "There are still three days left on vacation, why did you come back early?"

"Don't mention it, this trip was a torment. Jiuzhaigou is crowded with people. You can only see the head and nothing. It's easy to just go back to the laboratory." Professor Zhao said with a smile: "I want to use Go to the third laboratory, I heard that the key is with you?"

"Yes, you wait."

Professor Zhao took the magnetic card handed by Sun Cheng, turned around and went out.He knew Sun Yi, walked past Sun Yi, nodded to him with a smile, and looked at several people before leaving.

The four bid farewell to Professor Sun Cheng again, walked out of the office, and saw the back of Professor Zhao leaving.There were several students following him, and Wei Shuxun noticed that the figure of one of the students seemed familiar, where did he seem to have seen him?

With the guidance of Professor Sun Cheng, the progress of making the signal booster is very fast.The four of them summed up the problems they encountered once a day, and went to ask Professor Sun Cheng for advice in the evening.It's not that they are lazy. Although Professor Sun Cheng will reprimand them, he will explain design mistakes, correct ideas and production methods, and precautions to them in detail every time.If there is an opportunity to learn, the four of them certainly will not miss the opportunity.

Wei Shuxun ran into Professor Zhao several times in the laboratory building, and he also figured out who the person he felt similar to before was Xu Yuanjun.

Xu Yuanjun's appearance has completely changed. His originally slightly long hair was cut into a neat crew cut, his cheekbones were raised, his chin was flattened, his eyebrows became thicker, and he no longer wore glasses. He looked like an honest and honest student.

Wei Shuxun didn't recognize him at first, until he ran into Professor Zhao once, when the four of them stopped to chat with Professor Zhao, Wei Shuxun felt a faint gaze, sweeping from the three people beside him to him, his intuition was keen , Immediately raised his head and stared, among the students behind Professor Zhao, he saw Xu Yuanjun who had completely changed his appearance, with a simple and honest face.

Wei Shuxun still didn't recognize him at this time, he just felt that the man's eyes were different from his simple and honest appearance, so he couldn't help but take a few more careful glances.Xu Yuanjun was probably afraid that Wei Shuxun would miss him, so he said his name and mouth shape, Wei Shuxun immediately understood, turned his head indifferently, and never looked at Xu Yuanjun again.

When I returned to the dormitory at night, I received a call from Xu Yuanjun, asking if any of his friends talked about Professor Zhao or inquired about Professor Zhao, Wei Shuxun naturally answered no.Registration is about to close, and the signal booster is not yet ready. Everyone is busy discussing technology all day long, so there is no time to talk about Professor Zhao.

Originally, Wei Shuxun didn't understand Xu Yuanjun's mission at all, but when Xu Yuanjun asked, he knew that Xu Yuanjun's mission was to protect Professor Zhao, which made him a little uneasy.

"Hey, is it okay for you to contact me like this? Are you afraid of being discovered by criminals?"

"It doesn't matter. If I am attacked, I will know that the spy is you." Xu Yuanjun said without any pressure: "Even if I die, someone will finish you."

"Hey, how can this happen, what if you are really attacked!!"

"Anyway, since you know, you just happen to be a freshman in University A, so you won't be easily suspected." Xu Yuanjun said, "Please help me to pay attention to whether there are any suspicious people near Professor Zhao."

"I'll try my best." For Zhou Quan's sake, Wei Shuxun didn't refuse.Anyway, he has good hearing, and he can hear far away as long as he listens carefully. As an ordinary freshman, he is not afraid of being suspected.

The signal booster has already made a prototype, a square box half the size of a mobile phone.The box is made of stainless steel, carefully polished, sanded, and sprayed.The black metal box looks very textured, and Wei Shuxun painted a dragon on it with white paint, which is more imposing and dignified.

Feng Wei looked at the box and smiled at Liu Yongdong: "When you gave the solar energy storage device back then, it would have been nice if you had used such a casing. I guarantee that the beauty will not refuse."

Liu Yongdong shook his head, took the box, and carefully packed the accessories that had been prepared into the small box one by one according to the design drawing.From a practical point of view, this box is still too big.Half the size of a mobile phone, it is not convenient to carry it around.But this is just for the convenience of the competition. If it is used for commercial use, the box will have to be reduced proportionally, probably as small as the size of a memory card.

The signal booster has been formed, and several experiments need to be done, and then it is to take pictures, scan, and sign up by email.None of this has anything to do with Wei Shuxun, he is only in charge of laying hands and killing people.However, I have learned a lot under the guidance of Professor Sun Cheng in the past few days. We still go to Professor Sun Cheng's office every evening to receive guidance for problems that we can solve by ourselves.

According to Sun Yi, he doesn't often have the opportunity to be taught by Professor Sun, so he should take the opportunity to learn more.

"I said, Professor Zhao..."

Feng Wei suddenly mentioned Professor Zhao, Wei Shuxun's heart tightened, and he looked up at Feng Wei.Feng Wei didn't notice it, and continued: "Professor Zhao teaches something. I think everyone in the laboratory building respects him very much."

"I don't know too much." Sun Yi replied: "I heard from my father that he is an academician of the National Academy of Sciences and has his own laboratory and students outside. He teaches optics and electronics at school, so I don't know anything else."

"Sounds very powerful." Feng Wei gave a compliment and ignored it, turning to Wei Shuxun: "Shuxun, what about the friendship you mentioned last time? When will it start?"

Wei Shuxun pushed him away: "Let's talk after the game, don't distract yourself at this time."

"How can this be a distraction?" Feng Wei exclaimed, "It's a good time to know each other now. When the time comes, we will ask the beauties to help us out, and we will be able to cheer up even more!"

Liu Yongdong and Sun Yi turned their heads and pretended not to hear, Wei Shuxun couldn't laugh or cry.At the same time, he was relieved from the bottom of his heart.

When he went to the laboratory building two days ago, he heard a student who was reading by the pond outside the laboratory building say: "...No chance...There are people around, it's hard to get close..."

Because he was far away, he couldn't hear clearly even if he listened carefully, and Wei Shuxun didn't dare to walk over to listen.Accompanied by Sun Yi and the other three, he walked into the laboratory as if nothing had happened.In the office, Wei Shuxun sent a text message to Xu Yuanjun.Because there was nothing more to teach them, Professor Sun Cheng only encouraged them to go back, and it took only ten minutes.When Wei Shuxun walked out of the laboratory, the people by the pond had disappeared.I didn't see him again for a few days.

Wei Shuxun estimated that he had already been caught, so he didn't care anymore.Two days later, I occasionally heard two female students whispering: "The tongue has been caught, they should be alarmed, and they dare not come to Professor Zhao."

"The target may be transferred to Professor Xu of the Institute of Science and Technology, so we can also prepare to withdraw."

At a distance of more than ten meters, the two girls did not guard against Wei Shuxun. They stopped talking when they saw him approaching, and casually talked about the skirts that are popular this summer.

Wei Shuxun heaved a sigh of relief, this is his school, and it was hard for him to return to being a student in a serious manner. He didn't want any bad things to happen in his school.It would be best if those unknown gangsters didn't come, lest a professor be killed or kidnapped, which would probably cause a big riot in the school and make the teachers and students uneasy.

Not long after that, the "students" around the laboratory building gradually disappeared, and Wei Shuxun was still his ordinary good student, pretending he didn't know anything.The experiment of the signal booster has passed, and the four of them climbed a mountain specially for this purpose, and tested it on the top of the mountain with no signal, and the result was satisfactory.

Take a video and send it to the official mailbox together with the information of the four people and the scanned copies of their student ID cards. Then you just need to wait for the official phone call.
