Chapter 978: Cable telegraph

"Yes, let us see what this... Telegram!"
In the laboratory, Niu Ben was a little impatient. He had seen him in Qingzhou for ten years and had not seen anything for half of his life.
He Dong grinned. For those who are immersed in the laboratory, it is the greatest comfort to be able to appreciate the fruits of their labor.
So he said, "My lord, the two generals, please follow me."
After all, he led the three to a telegraph machine.
Now the three of them are in front of a transmitter. This transmitter is very simple. It is actually a power switch, but unlike modern switches, this switch is a guillotine switch.
From this guillotine switch board, there are two wires leading to the ticker which is ten meters apart. The ticker is composed of a coil wrapped in copper wire, an iron sheet on the coil, a paper roll and a pen. .
"Two generals, this is a complete telegraph machine. You mainly press the switch, and the whole circuit will be connected. The copper wire coil is energized to produce magnetic force to attract the iron sheet and make a beep. This is a signal, and When the current is cut off, the iron sheet will make a click when it returns to its original position. This is the second signal. The combination of the length of these two signals can send intelligence to the other party." He Dong explained to Niu Ben and Luo Quan.
As for Xiao Ming, he didn't need to explain at all, because the whole set of codes he got was given to him by Xiao Ming, and now he sent codes according to the small book he gave.
Niu Ben and Luo Quan were naturally confused. He Dong explained that they looked at Xiao Ming helplessly.
At this time, Xiao Ming said: "You two tell He Dong a word, don't let me know, let He Dong send me by telegraph later, and I will tell you what you just said."
"There is still such a thing? Isn't this a good wind?" Niu Ben looked incredulous, but turned his head and said a word to He Dong.
He Dong understood. He sat in front of the telegraph and used the code given by Xiao Ming to initiate a telegram. When He Dong sent the telegraph, the iron piece touched the pen. This pen began to draw the length on the white paper as the iron piece moved. One polyline.
After He Dong sent the telegram, Xiao Ming said: "Luo Quan is not a thing!"
Niu Ben was instantly dumbfounded, and Luo Quan scolded angrily: "You are not a thing, old mad cow!"
"Hahaha..." When Luo Quan scolded Niu Ben, he was not angry, but he was happy. He said, "I didn't expect this thing to be so magical. It's just the emperor. It's too close."
"This is no problem. I asked Su Liangcai to bury the telegraph line by the way. As long as there are enough wires, you can go as far as you want. The telegraph is only a flash of the word for thousands of miles. As for those who have not established thermal power generation. For the city of the factory, temporary use of small generators is enough to maintain the telegraph."
The small generator in Xiao Ming's mouth is the small power generation equipment made by Su Liangcai when he first generated power in the laboratory, which is equivalent to a mini thermal power generation unit.
This thing is enough to provide a government office's power supply, so that the cable telegraph will not be restricted by the lack of thermal power plants.
Once the telegram is covered by the country, the imperial court will control the country more timely in the future.
"Thousand Miles Sound Transmission is just a flash of fingers?" Niu Ben and Luo Quan spit in their mouths. In their eyes, they are really supernatural skills.
"Technology is really amazing. It's no wonder that the emperor wants to promote technology at all costs, and he also allows the underachievers of the country to go to school for free. If there are thousands of underachievers who understand technology, who else can shake the country? "Niu Ben was excited and the ground was red.
Luo Quan said, "Yes, since they are all allowed to go to school for free, this must be done for them to study hard, otherwise they will play the board!"
He Dong couldn't help but touched his when he heard this. He said: "We students don't have to suffer from the board in the college. These beginners, middle schools, and high schools will definitely only be more severe."
Xiao Ming grinned smirkly, and he was really tight on education. There is no such thing as quality education in this era. For him, instilling scientific and technological knowledge is the primary task.
Therefore, the beginners, middle schools, high schools, and universities of Dayu are not based on the age of contemporary schools, but are based on the standards of Dayu. It takes only nine years from beginning to high school graduation, that is, three years of beginning school. Three years in middle school and three years in high school.
He went to school at the age of six until he graduated at the age of fifteen. After four years, he completed college and entered all walks of life.
He thinks this time is quite short, but for the people of Dayu, this time is still very long. After all, after ten years of hard work, you can be the top scholar in the ranks, and the current education system requires thirteen. year.
"Education is the foundation of a strong country, and I will naturally not despise it." Xiao Ming said in a positive tone.
Now Dayu has gone through a difficult ten years, from zero industrial foundation to between the first industrial revolution and the second industrial revolution~EbookFREE.me~ Now he needs more elite talents to make Dayu The technology is moving forward, and these have laid the foundation since they were young, and the comprehensive ability of the elites who entered the laboratory after 13 years of education will definitely surpass those who are halfway through Lin Wentao.
At that time, the technology of Dayu Country will be able to achieve rapid improvement. After all, thanks to the efforts of the older generation, the industrial foundation has already been established.
After experiencing the cable telegraph, Xiao Ming looked at the three glass tubes that were being assembled in the experiment. These were the electron tubes needed for wireless telegraphy.
This kind of tube is simply a signal amplifier, and only with this thing can the radio travel farther.
However, this kind of electron tube is very big, because it is the most primitive electron tube, the material has not yet risen to the level of semiconductor, only the most primitive gate rare earth material is used, but even so, this is also a problem for He Dong and his team. , And this is what their laboratory is really studying.
After all, the cable telegraph is too simple and does not require more than 30 people to study together.
"The cable telegram is okay, and I can't relax this." Xiao Ming tapped the tube.
He Dong knows, he said; "Now we are communicating with Lutong's School of Chemistry, hoping that they will help us with materials. As long as the materials are in place, this tube will not be a problem. After all, welding will not be a problem after electricity is turned on."
"Well, I will ask him to cooperate with you." Xiao Ming patted He Dong on the shoulder.
Calculated by time, European technology is now in the time of the big bang, and various inventions and creations will emerge in endlessly, because this is the result of European technology accumulation.
In addition, they have been guided by the scientific and technological achievements of the country, they will avoid many detours and accelerate technologically.
Therefore, he cannot relax in scientific research.
