Tech House System

The game time is approaching, and we can no longer study slowly in a hurry. After the three discussed, they decided to go to Sun Yi's father, Professor Sun who works in the school for guidance.

Wei Shuxun followed behind them with the toolbox, listening to Sun Yi and Liu Yongdong discussing the air interference in signal transmission as they walked, asked Feng Wei: "Can you ask the professor for help?"

"Of course." Feng Wei nodded: "Many schools also have special organizations that teach and guide everything from design ideas to formulas to design drawings. They just need to do it themselves. The students are just puppets. I don’t like this level of competition, so students participate voluntarily. You can go to the campus honors section of the school to find a lot of interest groups participating in the competition.”

Wei Shuxun handed the toolbox to Feng Wei, and logged on to the school forum with his mobile phone. Sure enough, he saw a lot of "The students who participated in the National Undergraduate Electronic Design Contest joined the group, everyone encouraged each other", "Need automatic control" Professional, students who want to participate in the competition come to sign up.” A whole page down, most of them are postings like this.

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

"Because there are no conditions, there are many people participating, and it is not certain how many people can pass." Feng Ji said, with pride on his face: "However, the number of students in University A has always been the most, last year. It accounts for half of the entire competition group, so I have to rely on this competition to give Liu Yongdong a face."

Wei Shuxun has no sense of collective honor, nor does he need to be famous in competitions. He just nodded and took back the toolbox. He can't help with technology, and he can only express it by selling labor.

Sun Yi's father, Professor Sun Cheng, is an old man in his 50s. He also wears a pair of thick black-rimmed glasses. very serious person.

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

Reading the design picture, he said: "The idea is very wrong at the beginning. Although the permanent magnet coupling can receive the signal, the receiving distance is not far, and it is easily disturbed by the air. How can we do it? Signal boost..."

Continue reading while reprimanding. The four stood side by side in front of his desk, bowing their heads and being disciplined. Although he was stern, but the content was real, Wei Shuxun didn't feel disgusted when he listened to it, and he took it down carefully while listening.

Professor Sun Cheng finished reading the first design drawing, and then began to read the second design drawing. This blueprint was revised overnight by the three of Sun Yi last night. They had not tried it yet, so I brought it directly to Professor Sun Cheng for advice.

Professor Sun Cheng looked at it for a moment, then nodded: "This time it's almost the same. The idea of ​​signal remote sensing is correct. But the signal is easy to connect in series, so it should be replaced with signal stable remote sensing and an arch line static program. We need to add another subroutine to distinguish..."

As he spoke, he started to mark on the design drawing.

Wei Shuxun saw that he simply corrected the design data. After he read it, he couldn't help asking: "Professor Sun, do you already have a signal booster?"

If it's on the market, they can't use it to compete.

"It shouldn't be there yet." Professor Sun Cheng shook his head: "I haven't heard of it."

"Then how do you know the design so well?"

"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 over the design 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 walked in. He wore rimless glasses and was slightly fat. He walked into the office in loose sportswear, swept over the four Wei Shuxun, and asked with a smile, "Professor Sun, are you busy?"

"Professor Zhao, are you back?" Professor Sun Cheng got up and asked respectfully, "There are still three days of vacation, why did you come back earlier?"

"Don't mention it, this trip is really a pain, the people in Jiuzhaigou are crowded, just see the heads, and see nothing, just go back to the laboratory and stay at ease." Zhao The professor smiled and said, "I want to use the third laboratory. I heard that the key is with you?"

"Yes, you wait."

Professor Zhao took the magnetic card handed by Sun Cheng and turned to go out. He knew Sun Yi, walked past Sun Yi and nodded to him with a smile, then glanced at a few people before leaving.

The four said goodbye to Professor Sun Cheng again, walked out of the office, and saw the back of Professor Zhao leaving. There were several students behind him, Wei Shuxun found that one of the students seemed familiar, where did he seem to have seen it?

With the guidance of Professor Sun Cheng, the production of signal boosters is progressing rapidly. The four of them summed up the problems they encountered once a day, and in the evening they went to ask Professor Sun Cheng for advice. It's not that they are lazy. Although Professor Sun Cheng will reprimand them, he will explain to them in detail the design mistakes, correct ideas and production methods, and precautions every time. Given the opportunity to learn, the four of course did not miss the opportunity.

Wei Shuxun met Professor Zhao several times in the laboratory building, and also figured out who the person who seemed to be similar last time was Xu Yuanjun.

Honest and honest student.

Wei Shuxun didn't recognize him at first, until he ran into Professor Zhao once. When people swept him, he had a keen intuition and immediately raised his head to stare. Among the students behind Professor Zhao, he saw Xu Yuanjun, who had completely changed his appearance and had a simple and honest face.

Xu Yuanjun estimated that he was afraid that Wei Shuxun would miss him and say his name and mouth shape, Wei Shuxun immediately understood, if he turned his head ignorantly, he would never look 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. The registration deadline is about to close, and the signal booster is not ready. Everyone is busy discussing technology all day long, and there is no time to talk about Professor Zhao.

Originally, Wei Shuxun didn't understand Xu Yuanjun's mission at all. When Xu Yuanjun asked this, 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? Aren't 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 pressure: "Even if I die, someone will solve you."

"Hey, what if you were attacked!"

"Anyway, now that you know it, you just happen to be a freshman of a university, and it is not easy to be suspected." Xu Yuanjun said: "Please help me pay attention to whether there are any suspicious people near Professor Zhao."

"I try my best." For Zhou Quan's sake, Wei Shuxun did not refuse. Anyway, he has a good ear, as long as he listens carefully, he can hear very far. As an ordinary freshman, he is not afraid of being suspected.

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

Feng Wei looked at the box and smiled at Liu Yongdong: "When you sent the solar energy storage device, it would be great if you used this kind of casing. Make sure that the beauty will not refuse."

Liu Yongdong shook his head, took the box, and carefully put the prepared accessories into the small box according to the design drawings one by one. From a practical standpoint, the box is still too big. Half the size of a mobile phone, it is not convenient to carry on the body at all. But this is only for the convenience of the competition. If it is used for commercial use, the box should be reduced according to the proportion, and it is estimated that it should be as small as the size of the memory card.

The signal booster has been formed, and several experiments are needed, 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 responsible for attacking and gathering people's heads. However, I have learned a lot under the guidance of Professor Sun Cheng in the past few days, and everyone still goes to Professor Sun Cheng's office every evening for guidance on problems that they can solve by themselves.

According to Sun Yi, he does not often have the opportunity to receive the guidance of Professor Sun, so he still takes the opportunity to learn more.

"I said, Professor Zhao..."

Feng Wei suddenly mentioned Professor Zhao, Wei Shuxun felt tight, and looked up at Feng Wei. Feng Wei didn't notice, and continued: "Professor Zhao teaches something. I see that everyone in the laboratory building respects him very much."

"I don't know." 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 in school, and the rest It's not clear."

"It sounds very powerful." Feng Wei praised and ignored it, turning to Wei Shuxun: "Shuxun, what about the friendship you said 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 good to know each other now, and then ask the beauties to help us out, and we will be even more energized!"

Liu Yongdong and Sun Yi turned their heads as if they didn't hear it, Wei Shuxun was dumbfounded. At the same time, he breathed a sigh of relief.

When he went to the experimental building two days ago, he heard a student who was reading by the pond outside the experimental building say: "...no chance...there are people around, it is difficult to approach..."

Because it was so far away, I couldn't hear it clearly, so Wei Shuxun didn't dare to walk over to listen. He accompanied Sun Yi and the three of them into the laboratory as if nothing had happened. In the office, Wei Shuxun texted Xu Yuanjun. Since there was nothing to teach them, Professor Sun Cheng let them go back after only a few words of encouragement, which only took about ten minutes. When Wei Shuxun walked out of the laboratory, the people by the pond had disappeared. I didn't see you again for a few days.

Wei Shuxun guesses that he has been caught, so he doesn't care. Two days later, I occasionally heard two female students whisper: "The tongue has been caught, they should be alerted, and they dare not come to Professor Zhao."

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

At a distance of more than ten meters, the two girls were not guarded against Shuxun. They stopped the conversation when they saw him approaching, and casually talked about the popular skirts this summer.

Wei Shuxun breathed a sigh of relief, this is his school, he finally became a serious student, he didn't want anything bad to happen to his school. It would be best if those gangsters who didn't know who they were would 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" surrounding the experimental building gradually disappeared. Wei Shuxun was still in front of his ordinary good students, pretending to know nothing. The experiment of the signal booster has been passed, and the four of them specially climbed a mountain for this purpose. They tested it on the top of the mountain without signal, and the results were satisfactory.

Take a video and send it to the official mailbox together with the information of the four people and the scanned copy of the student ID card, and then just wait for the official phone notification.
