After the remote control system is built, the next thing on the agenda is the image transmission link.
During the two days of the weekend, Wang Ning and Bai Zhen discussed in detail the technical points of using the icom725 amateur radio station for image transmission.
"Use a camera, right?" Banxia squatted on the floor of the living room, holding the uv9r walkie-talkie in her hand, and the cameras in front of her were piled up like a mountain. "I found a lot of cameras, and I may have emptied Zhujiang Road."
In the past week, the girl went to Zhujiang Road to search every day, and returned a huge amount of electronic waste.
What liquid crystal monitors, computer mainframes, main boards, coaxial cables, cameras, mice, keyboards, those that are not needed, those that are not recognized, are all packed in sacks and dragged back by a small trailer.
This is a world of trashy ecstasy.
"I have a lot of cameras here, which one should I use?" Ban Xia asked.
After the remote control system was established, the communication was much more convenient. The most notable change was that the girl no longer had to stay in the room all the time.
She can walk around the house with the mobile phone.
"It's best to use a uvc camera, over." Bai Yang's voice came from the mobile station.
"bg4mxh, what is a uvc camera?"
"Uvc means usb video class, which is a standard protocol." Bai Yang replied, "Simply speaking, it is a driver-free camera that can be used after plugging it in. It is very convenient, over."
"Then which one is the uvc camera?"
Ban Xia picks and chooses at will, there are so many cameras, some are hemispherical, some are cylindrical, some are cuboid, and some have a bracket like a small desk lamp.
"The vast majority of webcams are UVC cameras, and all the ones you find are." Bai Yang said, "You just need to pick one that can still work normally, over."
? Establishing an image transmission link is much more complicated than a remote control system.
Wang Ning said that there is not much difference between a pure analog repeater like gr3188 and 725 in terms of communication protocol, because it itself is composed of two base stations, and they are all in the same family. If the setup is correct, the relay station and Guailiangwu align their buttocks with their mouths, and their mouths with their buttocks, and the entire link can make do with it.
However, image transmission is different.
The image data collected by the camera needs to be transferred to Bai Yang by turning two or five, but the camera and the amateur radio station are not the same family. The network camera is a newcomer, and the amateur radio station is an old antique. There is no doubt that the data exchange between them is Chickens and ducks cannot understand each other, so they need a powerful translator, a core computer, and a connection hub to undertake the transcoding function.
To transcode the image data into a signal that can be transmitted by an amateur radio station, there is no doubt that the best person to do this is a computer.
The computer is the most convenient and powerful platform at the same time. 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, "All of them are rusty, and they don't respond when they are plugged in oops!"
She suddenly exclaimed.
"What's the matter? Missy? What happened?"
It took a few seconds for the girl to reply:
"It exploded, this motherboard exploded, and there was a lot of smoke, ahem I went out to avoid it."
Since they couldn't find a usable computer, Wang Ning and Bai Zhen decided to settle for the next best thing. They began to discuss the feasibility of using 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 single-chip microcomputer and DOS. You know that the old antiques in the army use DOS a lot." Bai Zhen said, "I know a little bit of linux."
"To what extent?"
"Can spell."
Ban Xia ran to the balcony and opened the window to let the night wind blow in, then leaned on the balcony and looked out leisurely.
"I feel like my life has meaning again." She said suddenly.
Bai Yang was taken aback.
"Why do you say that? over."
"Before I contacted you, I lived a day. Even a day, I didn't know why I was still living in this world, and I didn't know what I was going to do. After the teacher was gone, I lived alone in the house, always Sitting for a whole day, not talking all day, and then gradually I can't even talk, because no one talks to me anymore, but I can't talk to myself, right? I always talk to myself Will become crazy, so I can only force myself to sing??¡± Ban Xia said, ¡°If I don¡¯t sing, I¡¯m going to be dumb. Fortunately, you contacted me now. If it¡¯s two years later, I can only talk to you like this: woo woo woo! Woohoo! "
She giggled.
"But now I feel that life is so interesting. I finally have something to do. Whether it's picking up garbage on Zhujiang Road, or refitting the repeater and 725, I go to bed the night before and think about what I'm going to do tomorrow. It¡¯s a great life, and I love it so much.¡±
"Uh don't you think it's troublesome and boring to do this?" Bai Yang asked, "Aren't you tired? over."
"I don't think so." Ban Xia said.
"Miss, you still need to learn programming later, so don't talk too much." Bai Yang reminded, "That's more boring and difficult, over."
"Although let the horse come here!"
Ban Xia is full of ambition, what could be more difficult than her previous life?
¡ª¡ªTwo days later she was rolling all over the floor:
"I don't do it anymore, I don't do it, I don't do it, I don't do it! It just can't get along with me! It's unscientific! It's 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?" Ban Xia asked, "We can only get in touch at ten o'clock in the evening. It's already dark outside, what can we photograph?"
"We are still discussing this." Bai Yang replied, "Miss, image transmission is not the point, the point is to widen the data transmission link, the current method of only using radio voice communication is too restrictive, we need to pave the road first Well, bigger cars are only possible when the road is paved, do you understand? over.¡±
The girl nodded.
She could understand what Bai Yang said, but she didn't know what to do after widening the data channel.
It is obvious that Ban Xia knows almost nothing about the past disaster that destroyed the world.
And there is too little information about that disaster left in this world. Human civilization was completely destroyed in a very short period of time, and the bones of seven billion people remained, only crashed planes, burned-out cars, and people on the ground. The crater on the ground symbolizes the resistance that once existed, and there may be relevant detailed information preserved in some corner of the earth, but it may be in Greenland, it may be in the deep Pacific Ocean, it may be in Cheyenne Mountain North American Air Defense Command, all are Pinellia is impossible to touch.
The girl was puzzled, but she still did all the work according to the plan.
Maybe there is some way over there?
¡ª¡ªBai Yang actually didn¡¯t know of any solution, he just followed Zhao Bowen¡¯s instructions and pushed forward the work before he came back.
If at this moment, one of the seven billion people in the world has a comprehensive plan in mind, then this person is undoubtedly Zhao Bowen.
Bai Yang didn't know where Lao Zhao was now, and he hadn't called to ask for applause for a long time, and there was no news of this person for many days, as if he had evaporated from the world.
Sometimes Bai Yang thinks wildly, thinking that Uncle Zhao may have been locked up as a mental patient at this moment, and his mobile phone and everything have been confiscated, so he has lost contact for a long time¡ª¡ªThinking about it, this scene appeared in his mind: Zhao Bowen was locked up In the ICU, with disheveled hair and sunken eye sockets, I slammed on the iron door and yelled at the nurse to let me out! If you don't let me out, the world will be destroyed! Then there was a burst of laughter from the patients. An older mentally ill man next door counted his fingers and comforted him by saying that you don't have to worry about young people. Arhats will come to the world by then.
If this is the case, the world will really be over.
With Bai Yang's small mind, he couldn't figure out what Zhao Bowen was planning. Uncle Zhao seemed to be playing a big game of chess.
Bai Yang was waiting for Zhao Bowen's next move.
Uncle Zhao's chess move was successfully made, and they might have a way to see the truth of the doomsday disaster, but before Zhao Bowen's chess piece fell, there was a sudden news from bg4msr that could make everyone jump up.
This is a major turning point, allowing Bai Yang and others to take a big step forward towards the truth.
This big step is thanks to a slipper.
That's one small step for a slipper, but one giant leap for mankind. - Didn't finish reading? Add this book to your favoritesI'm a member and bookmarked this chapterCopy the address of this book and recommend it to your friends for pointsChapter error? Click here to report
