The so-called wired telegraph, the principle is actually very simple.
It is to convert the information into electric current, then send it out through the wire, and receive it by the terminal.
Therefore, the transmitter is actually a keyed signal transmitter, and the receiver is an interpreter.
The principle of the artificial telegraph is that a person manipulates the electric key, and the "dot" and "stroke" formed by opening and closing form a signal, which is transmitted through the wire.
Morse also stood on the basis of his predecessors and designed a set of codes to encode letters and numbers for easy transmission through circuits.
No complicated circuits are needed, only one line is needed, and the problem can be solved!
To put it bluntly, it's just a piece of paper, just see if it's pierced or not.
But this kind of improvement is much more reliable than that electrolytic signal, which is also the basis for the development of wired telegraphy.
What Sulu is going to show is this set of encoding and transcoding methods.
"With this, and two more terminals, wired telegraphy is possible! It will change the world..."
The speed of information dissemination is the difference between primitive society and modern society!
"I have to say, sometimes the feeling of making history is quite good!"
Looking at his own design, Sulu nodded: "This patent alone is enough for me to eat for a lifetime. If I set up a telegraph company myself, it will be even more profitable!"
The reason why he took out the technology of wired telegraphy. More at this time, it is to attract the attention of the above.
Only genuine talents can attract the attention of Green Tree Fort's high-level executives and be absorbed into the interior!
This is not only an improvement of status, but also helpful to Sulu's many plans.
Therefore, he would rather suspend his cultivation on the extraordinary side, but also to get ahead in the electrical research institute.
Besides, he had another consideration in his mind.
Although both the White Eagle Federation and Green Tree Castle Laboratories paid great attention to patents, he was a man of few words after all.
And the interests and future represented by cable telegrams are too great, and it is hard to guarantee that there will be no unscrupulous guys jumping out.
"It's okay if you cooperate, but if you're really shameless enough to directly snatch the research results... Hehe...'
Sulu sneered secretly.
He still has a wireless telegraph weapon in his hand!
The principle of wireless telegraphy is actually similar to that of wired. It also converts information into electromagnetic waves, from low frequency to high frequency, and transmits and receives them through high-power antennas.
In effect, the propagation medium is changed from wires to air.
'If someone wants to steal my achievements, let them do it... After the other party has made a major construction project and laid the telegraph network, I will take out the wireless telegraph technology, and I will not kill these scumbags! ! '
Compared with wired telegraphy, wireless telegraphy only needs a tall transmitter.
This cost is insignificant compared to the cost of laying telegraph wires across the continent, or even across the ocean.
At that time, if he still can't kill them, Sulu can add a gram to his surname!
…
The autumn on the east coast of the Federation is not cold. In the slight cool breeze, Sulu came to the laboratory.
"Where's the professor?"
He looked at Cecilia who was working, and asked in a low voice.
"He's not in a good mood, don't bother him if you don't have anything special."
Cecilia replied.
This Sulu knows.
Professor William's large-scale communication experiment can be said to be a success or a failure.
The success lies in proving that it is indeed possible to use electric current to transmit information, and the speed is still very fast!
The failure lies in the cheating electrolytic terminal, which is not only cumbersome to operate, but also easy to make mistakes, and requires a lot of wiring, which is extremely expensive.
Therefore, the funding that Professor William hoped for was directly shot, and it is no wonder that he is in a good mood.
"I have something important. I wrote a paper and want to publish it internally!" Sulu replied.
In fact, in terms of the status of Green Tree Castle Laboratory, being able to publish internally is no different from publishing the entire federation.
"Hiss..."
Unsurprisingly, Cecilia gasped: "You... thesis?"
Although she knew that this newcomer was very powerful, she never thought that the other party could be so powerful!
"Let me see."
She took the manuscript and glanced at it: "From direct current, the idea of current?"
"This is my topic, with the consent of Professor William."
Sulu explained a few words beside him.
"Excellent and inspiring!"
Cecilia returned the manuscript to Sulu: "I think it is worth at least five points! You can go to the tutor, he is in the office!"
"Thanks!"
Sensing Viktor's envious eyes, Sulu walked into the office unconsciously.
"professor!"
William was behind the desk, planning something, with a single expression, unable to tell whether he was happy or angry.
"This is my thesis."
After thinking about it, Sulu still handed in the manuscript.
"Um!"
William took it, glanced at it, and was a little surprised: "Compared to before, your derivation is more mature and rigorous... Very good, I will submit it for review, and you can go out."
"Thanks!"
Sulu saluted and exited the door gently.
Viktor looked at his back, and finally couldn't help but said: "A newcomer wants to publish a paper? Don't be scolded by the tutor..."
Andrew, who was wiping the table next to him, trembled immediately when he heard this.
"Well, Viktor, Sulu is indeed capable and talented!"
Cecilia had to admit that this new entrant was very capable, especially in the study of electricity, as if he had an innate talent.
When others were struggling to move forward in the dark, he held a torch and ran towards the goal.
It also runs very fast, just like a wild horse having fun!
…
late at night.
Institute of Electricity.
The Green Tree Castle Laboratory is divided into an inner ring and an outer ring, which are under the unified jurisdiction of the Green Tree Council.
The ninth seat, Slaiden Water, looks like an ordinary old white man with silver hair, but his eyes are very bright, like two sparkling sapphires.
As one of the leaders of the laboratory, he is of course a transcendent.
His old appearance could not stop his exuberant energy in the slightest.
Document after document was quickly reviewed by him and distributed, passing orders one by one.
Suddenly, he snapped his fingers: "The review committee? Are there any papers that they can't judge?"
In his hand, there was an extra paper.
Green Tree Fort's internal papers are reviewed very strictly.
As a master figure in the field of electricity today, Slaiden Water also made his name there.
Once he encounters an article that the other party cannot review, he is obliged to appear on the stage.
"interesting."
Sladen Water put on his reading glasses and looked at the beginning of the paper: "On direct current and some derivation assumptions?"
He looked at it for a long time, and even the black tea on the table was cold.
After a long time, Slaiden Water looked at the author: "Is Sulu Botley? Interesting!"
He immediately wrote and made the final reply: "The logic is clear, the thinking is concise, the review is passed, and it is recommended to reward 15 points."
