We Live In Nanjing

  Chapter 76 A small step for slippers, a big step for mankind

  The remote control system is set up, and the next thing on the agenda is the image transmission link.

  In the two days of the weekend, Wang Ning and Bai Zhen discussed in detail the technical points of using Icom725 amateur radio for image transmission.

  "Use a camera, right?" Banxia squatted on the floor of the living room, holding a UV9R walkie-talkie in his hand, and the cameras in front of him were piled up like a mountain, "I found a lot of cameras back, maybe the Zhujiang Road has been emptied."

  In the past week, the girl went to Zhujiang Road to search every day, and she scoured a huge amount of e-waste.

  What LCD monitors, computer hosts, motherboards, coaxial cables, cameras, mice, keyboards, those that are not available, and those that you don’t know, are all packed in sacks and pulled back in a small trailer.

  This is a world of ecstatic trash guys.

   "I have a lot of cameras here, which one should I use?" Banxia asked.

  After the remote control system was established, the communication really became much easier. The most significant change is that the girl no longer has to stay in the room all the time.

  She can walk around the house with her handstand.

  "UVC camera is best, OVER." Bai Yang's voice came from the console.

  "BG4MXH, what is a UVC camera?"

  "UVC means USBVIDEOCLASS, which is a standard protocol." Bai Yang replied, "Simply put, it is a driver-free camera that can be used when plugged in. It is very convenient, OVER."

   "Then which is the UVC camera?"

  Panxia picks and chooses, there are so many cameras, some hemispherical, some cylindrical, some rectangular parallelepiped, and also like a small lamp with a bracket.

  "The vast majority of webcams are UVC cameras, and the ones you find are all." Bai Yang said, "You only need to pick one that works normally, OVER."

  Establishing an image transmission link is much more complicated than a remote control system.

Wang Ning said that a pure analog repeater such as GR3188 is not much different from the 725 at the communication protocol level, because it itself consists of two base stations, both of which are family members. Don’t talk about the two, as long as the path is at the hardware level. Set up correctly, repeater and turn two to five buttocks to mouth, mouth to buttocks, the whole link can make do with walking.

  But the image transmission is different.

The image data collected by the camera has to be transmitted to Baiyang through the two or five, but the camera and the amateur radio station are not a family. The web camera is a new human being, and the amateur radio station is an old antique. There is no doubt that the data exchange between them is The chicken and the duck can't understand each other, so they need a powerful translation, a core machine, and a connection hub to take on the function of transcoding.

  Transcoding image data into signals that can be transmitted by amateur radio stations. If this can be done, there is no doubt that the best candidate is a computer.

  Computer is the most convenient and also the most powerful platform. As long as Banxia can find a computer that can work normally, all problems will be solved.

   "It's useless, these computers are useless." Banxia shook her head, "Everything is rusty, nothing happens when plugged in...Oh!"

  She suddenly exclaimed.

   "What's wrong? Miss? What happened?"

  A few seconds later, the girl replied:

   "It exploded, this motherboard exploded, and there was a lot of smoke, cough cough... I went out to avoid it."

  The computer could not be used, Wang Ning and Bai Zhen retreated, and they began to discuss the feasibility of the development board and Raspberry Pi in this system.

  "What system does the Raspberry Pi use?" Wang Ning asked.

   "Linux." Bai Zhen replied.

  "Are you good at developing on the Linux platform?" Wang Ning asked.

   "I am best at MCU and DOS. You know that many old antiques in the army use DOS." Bai Zhen said, "Linux I know a little bit."

   "How far can it be?"

  "Can spell it."

   Banxia ran to the balcony and opened the window to let the night breeze in, and then leaned on the balcony and looked out.

   "I think my life has meaning again." She said suddenly.

  White Poplar was taken aback.

   "Why do you say that? OVER."

"Before I contacted you, I had one day, even if one day, I don’t know why I’m still alive in this world, and I don’t know what I want to do. After the teacher is gone, I live alone in the house. I sat for a whole day, and didn’t talk for a whole day, and then gradually I couldn’t even speak, because no one talked to me anymore, but I couldn’t talk to myself, right? I always talk to myself. I’ll be crazy, so I can only force myself to sing.” Banxia said, “I’m going to be dumb if I don’t sing. Fortunately, you’re contacting me now. If it’s two years later, I can only do this to you. Speaking: Ouuuuuuuuuuuuuuuu!"

  She giggled.

"But now I think my life is so interesting. I finally have something to do, whether it's picking up **** on Zhujiang Road, or modifying the relay station and 725. I went to bed the night before and I can think about what I will do tomorrow. This kind of life is great, I love it so much."

   "Uh... don't you think it is troublesome and boring to do this?" Bai Yang asked, "Aren't you getting bored? OVER."

   "I don't think." Banxia said.

  "Miss, I have to learn programming later, so don’t talk too much." Bai Yang reminded, "That is more boring and more difficult, OVER."

   "Although let go!"

  Banxia is full of ambition, what can be more difficult than her previous life?

  ——Two days later she was rolling all over the floor:

  "I don’t do it, I don’t do it, I don’t do it, I don’t do it, I can’t do it! It just can't get through with me! This is unscientific! This is incomprehensible! The code I entered is obviously correct, why doesn't it work?"

   "BG4MXH, after the image transmission link is established, what data do you need?" Banxia asked, "We can only get in touch at ten o'clock in the evening. It's dark outside. What can I get?"

"We are still discussing this." Bai Yang replied, "Miss, image transmission is not the key point. The key point is to broaden the data transmission link. At present, the way to only use radio voice communication is really too restrictive. We have to pave the way first. Okay, after the road is paved, it is possible to pass a bigger car. Can you understand? OVER."

  The girl nodded.

  She can understand what Bai Yang said, but she doesn't know what she can do after expanding the data channel.

  It is clear that Banxia knows almost nothing about the past catastrophe.

And there is too little information about the disaster left in this world. Human civilization was completely destroyed in a very short period of time. Seven billion people have no bones, only crashed airplanes, burned out cars, and on the ground. The crater symbolizes the resistance that there was once. There may be relevant detailed information preserved in a corner of the earth, but it may be in Greenland, in the depths of the Pacific, or in the Cheyenne Mountain North American Air Defense Command. It is impossible to reach Pinellia.

  The girl was puzzled, but she still did all the work as planned.

  Maybe there is any way?

  ——Bai Yang didn’t know any way. He just followed Zhao Bowen’s instructions to push forward the work before he returned.

  If at this moment, one of the seven billion people in the world has a comprehensive plan in his mind, then this person is undoubtedly Zhao Bowen.

  Bai Yang didn't know where Old Zhao was now, and he hadn't called for applause for a long time. After this person went there for many days, there was no news, as if the world had evaporated.

Sometimes Bai Yang thinks wildly, thinking that Uncle Zhao may have been locked up as a mental patient at this moment, and his mobile phones have been confiscated, so he has been out of touch for a long time-thinking about it, this scene appeared in his mind: Zhao Bowen was locked up. In the intensive isolation ward, with unruly hair and sunken eye sockets, he slapped the iron door desperately and yelled at the nurse to let me out! If you don't let me go out, the world will be destroyed! Then it caused a burst of laughter from the patients. An older mentally ill man next door pinched and comforted him and said that young people don't have to worry about it. At that time, an Arhat will come to the world and a mighty dragon.

  If that were the case, the world would really be over.

  With the little mind of Bai Yang, he couldn't guess what Zhao Bowen was playing. Uncle Zhao seemed to be in the next big game.

  White Yang is waiting for Zhao Bowen's next move.

  Uncle Zhao’s successful move, they may have a way to see the truth of the doomsday disaster, but Zhao Bowen’s chess piece has not yet fallen, and suddenly there is a news from BG4MSR that can shock everyone present.

  This is a major turning point, allowing Bai Yang and others to take a big step forward toward the truth.

  This big step is due to a slipper.

  That was just a small step for slippers, but it was a big step for all mankind.
