Steel Dynasty - Chapter 981

[Chapter 975 Cable Telegraph]

“Yes, let us see this… telegram!”

In the laboratory, Niu Ben was quite impatient. He had seen nothing in Qingzhou for ten years and had not seen anything in half his life.

He Dong grinned. For those of them who are immersed in the laboratory, having someone appreciate the fruits of their labor is the greatest comfort.

So he said: “Your Majesty, the two generals, please follow me.”

After that, he led the three people to a telegraph machine.

What the three of them now have in front of them is a transmitter. This transmitter is very simple. It is actually a power switch. However, unlike modern switches, this switch is a guillotine switch.

There are two wires from this guillotine switch board to a telegraph machine ten meters apart. This telegraph machine consists of a coil wrapped with copper wire, an iron plate on the coil, a paper reel and a pen. .

“Two generals, this is a complete telegraph machine. Just press and hold the switch, and the entire circuit will be connected. The copper wire coil will be energized to generate magnetic force, which will attract the iron sheet and make a beeping sound. This is a signal, and When the current is cut off, the iron piece will make a clicking sound when it returns to its original position. This is the second signal. Through the combination of the length of these two signals, information can be sent to the other party,” He Dong explained to Niu Ben and Luo Quan.

As for Xiao Ming, there is no need to explain at all, because the entire set of telegrams he got was given to him by Xiao Ming, and now the telegrams are sent according to the small book he gave him.

Niu Ben and Luo Quan were naturally confused. He Dong had explained, and they looked at Xiao Ming helplessly.

At this time Xiao Ming said: “You two tell He Dong something, don’t let me know. Later, let He Dong send it to me using a telegraph machine, and I will tell you what you just said.” “

And this. What’s going on? Isn’t this Shunfeng Er?” Niu Ben looked in disbelief, but turned around and said something to He Dong.

He Dong understood, sat in front of the telegraph machine and used the code given by Xiao Ming to initiate the telegram. When He Dong sent the telegram, the iron piece moved the pen, and the pen began to draw different lengths on the white paper with the movement of the iron piece. A polyline of one.

After He Dong finished sending the telegram, Xiao Ming muttered: “Luo Quan is not a thing!”

Niu Ben was dumbfounded, and Luo Quan cursed angrily: “You are not a thing, old mad cow!”

“Hahaha …” After being scolded by Luo Quan, Niu Ben was not angry, but instead became happy. He said, “I didn’t expect this thing to be so magical. It’s just that the distance is a bit too close, your Majesty.”

“That’s okay, me .

Su Liangcai was asked to bury telegraph wires when laying the wires. As long as there are enough wires, you can go as far as you want. Using telegraph to send messages over thousands of miles can only take a blink of an eye. As for cities that have not built thermal power plants, they can be used temporarily. A small generator is enough to maintain the telegraph machine.” The

small generator Xiao Ming mentioned was the small power generation equipment Su Liangcai made during his first laboratory power generation, which is equivalent to a mini thermal power generation unit.

This thing is enough to provide the power supply of a government office, so that wired telegraphy will not be limited by the lack of thermal power plants.

Once the whole country of Dayu is covered by telegraph, the imperial court’s control over Dayu will be more timely in the future.

“Thousands of miles of sound transmission just for a moment?” Niu Ben and Luo Quan gulped. In their opinion, it was really a magical ability.

“Technology is really amazing. No wonder the emperor wants to promote technology at any cost, and also allows the poor children of Dayu to go to school for free. If there are thousands of poor people who understand technology, who else can shake Dayu?” “Niu Ben’s face turned red with excitement.

Luo Quan said: “Yes, since they are allowed to go to school for free, they must study hard, otherwise we will slap them!”

He Dong couldn’t help but touch his butt when he heard this, and he said: “We All the students in the academy will be punished, and these beginners, middle schools, and senior students will definitely be more severe.”

Xiao Ming gritted his teeth and smiled evilly. He really pressed hard on education. There is no quality education in this era. In other words, for him, instilling scientific and technological knowledge is the first priority.

Therefore, the junior high school, middle school, senior high school, and university in Dayu are not based on the age settings of contemporary schools, but are based on the standards of Dayu. The time from junior high school to high school graduation is only nine years, which is three years of junior high school. Three years of middle school and three years of high school.

They go to school at the age of six and graduate at the age of fifteen. After another four years, they complete college and enter all walks of life.

He thinks that this time is quite short, but for the people of Dayu, this time is still very long. After all, ten years of hard study can lead to the number one scholar and become an official, and the current education system requires thirteen years in total. Year.

“Education is the foundation of a strong country, and I will naturally not despise it.” Xiao Ming said with certainty.

Now Great Chongqing has gone through a difficult decade, from zero industrial base to between the first industrial revolution and the second industrial revolution.

Now he needs more elite talents to make Dayu’s science and technology move forward, and the comprehensive ability of these elites who have laid the foundation since childhood and entered the laboratory after thirteen years of education will definitely exceed those of Lin Wentao and other halfway monks.

Only then will Dayu’s science and technology be able to achieve rapid improvement. After all, thanks to the efforts of the older generation, the industrial foundation is already in place.

After experiencing the wired telegraph machine, Xiao Ming looked at the three glass tube-like things being assembled in the experiment. These were exactly the electron tubes needed for wireless telegraphy.

This kind of tube is simply a signal amplifier. Only by adding this thing can the radio transmit farther.

However, this kind of electron tube is very large, because it is the most primitive electron tube. The material has not yet reached the level of semiconductor. It only uses the most primitive gate rare earth material. But even so, this is a problem for He Dong’s team. , and this is what their laboratory is really studying.

After all, wired telegraphy is too simple and does not require more than thirty people to study it together.

“There is no problem with wired telegraphy, but we can’t relax on this.” Xiao Ming clicked on the electronic tube.

He Dong understood and said, “Now we are communicating with the School of Chemistry in Lutong, hoping that they can help us with materials. As long as the materials are in place, the tube will not be a problem. After all, welding will not be a problem after the electricity is turned on.”

“Yeah , I will ask him to cooperate with you.” Xiao Ming patted He Dong on the shoulder.

Judging by time, Europe’s science and technology has now reached a period of big explosion, and various inventions and creations will emerge in endlessly, because this is the result of the accumulation of European science and technology.

In addition, they have been guided by the scientific and technological achievements of Great Chongqing, so they will avoid many detours and accelerate their technological progress.

Therefore, he cannot relax in scientific research.
