Daming Town Haiwang

Chapter 1600, Lao Liu, Lao Liu, I am Lao Zhu
Beijing, Imperial College of Technology.

Liu Jin came here with an extremely excited expression.

"Wireless telegraphy has finally been researched!"

"Waiting for a moment is too long!"

No wonder Liu Jin was so excited. Ever since the electromagnetic induction phenomenon was discovered, Liu Jin has been waiting for these scientists in Ming Dynasty to research the wireless telegraph as soon as possible.

Because of the huge Ming Empire, it needs this technology too much.

The Ming Empire is really too big, and the exchanges between various regions are really too slow.

From Nanyun Province to the capital of Daming, even if it takes [-] miles to deliver the information in a hurry, it will take at least half a month to arrive, and it will take a month to go back and forth. .

If it is passed to the more distant Golden Continent, it will take even longer.

In this short period of time, the problem is not very serious, but if it takes a long time, it will easily lead to divisions within the Ming Empire and breed separatist forces.

Therefore, a means of efficiently transmitting information is particularly needed, and the most ideal is naturally wireless telegraphy.

Its technological content is not high. With the development of electromagnetic technology, it is not difficult to research wireless telegraphy. In particular, Liu Jin still knows some knowledge about wireless telegraphy and constantly gives guidance.

Now it is finally the research of wireless communication technology.

"Liu Gong~"

Lai Ji, the principal of Imperial College of Technology, waited respectfully for Liu Jin's arrival with the relevant personnel of electromagnetic communication technology.

"Don't be too polite, take me to see our wireless telegram."

Liu Jin quickly waved his hand and said.

"This way, Mr. Liu, please~"

Lai Ji said respectfully, Liu Jin is now the cabinet chief of the Ming Empire, and also the founder of Imperial College of Technology, a self-help person, and even a sponsor of radio-related technologies.

Liu Jin has funded the establishment of electromagnetic laboratories in Imperial College of Technology, Daming Institute of Technology, School of Mechanical Engineering and many other colleges, allowing many people to study electromagnetics in order to research wireless communication technology as soon as possible.

"How did you do it?"

While walking towards the laboratory, Liu Jin also asked in detail.

"Back to Mr. Liu~"

"Our school's electromagnetic laboratory, through repeated experiments and research, found that by continuously closing the circuit, under electromagnetic induction, an oscillating current will be generated in the circuit, and the frequency of this oscillating current is very high, reaching several Millions, tens of millions of times."

"Under such circumstances, we continue to carry out research and confirm the existence of electromagnetic waves. This kind of electromagnetic wave is invisible to our naked eyes. Its propagation speed is very fast, almost comparable to the speed of light."

"So we thought about whether we can use this electromagnetic wave to transmit information, so that long-distance instant communication can be realized."

Speaking of this matter, Lai Ji was very proud, and began to talk to Liu Jin about the principle of electromagnetic communication.

"Oh, there are electromagnetic waves~"

Liu Jin naturally seemed to understand half-understand. He knew everything, but he still pretended not to understand.

"Of course, the reason why this kind of long-distance communication technology can be researched is the greatest credit to the current Crown Prince."

"He was the first person in the field of electromagnetic research, and he was the first to discover the existence of electromagnetic waves."

Then, Lai Ji mentioned Zhu Houzhao classmate.

Hearing Zhu Houzhao, Liu Jin couldn't help raising his eyebrows slightly.

His Royal Highness, who is not doing his job properly, his biggest hobby now is creating human beings and researching various mechanical and electromagnetic technologies. He did not expect that he could really make contributions and achievements in the electromagnetic field.

"We have conducted a short-distance communication test beforehand, and this time we invite you to come over to test the long-distance communication situation."

"His Royal Highness, he is now in Huairou County, and we are in Xincheng, South District of Beijing. The distance between the two parties is already very long. If we can still communicate effectively, it shows that the electromagnetic communication technology is indeed reliable."

"Then in the next step, we will conduct more long-distance tests and conduct in-depth research in related fields to develop a feasible and reliable electromagnetic communication technology."

Lai Ji introduced in detail.

In fact, this technology has already been researched, and it is currently in the testing stage. It has been tested before, and this time it will be tested at a farther distance.

There is a distance of hundreds of miles from Huairou County to Xincheng Imperial College of Technology in the southern part of the capital. Such a long distance, if electromagnetic communication can be realized, it also means that it can continue to zoom in to a longer distance. test.

It also means that infinite electromagnetic communication technology has infinite value.

If electromagnetic communication technology could be used to transmit information from Nanyun Province to the capital in a very short period of time, then the Ming Empire's control over the entire huge empire would become easier and simpler.

It is no longer necessary to use the eight hundred miles to express information as before, which not only consumes a lot of manpower, material resources and resources, but more importantly, the speed is too slow to keep up with the development needs of the Ming Empire.

Soon, under the leadership of Lai Ji, Liu Jin came to the electromagnetic laboratory.

Before entering the laboratory, Liu Jin noticed the high poles erected above the laboratory building. There are many densely wound copper coils at the top. This should be a device for receiving signals.

"Liu Gong, this is a device used to receive the other party's signal. After the other party emits electromagnetic waves, we can receive them through such a device, and then combine them into regular transmission information according to the frequency of the electromagnetic wave. In this way, Long-distance unlimited communication can be realized.”

Seeing that Liu Jin noticed the coils on the building, Lai Ji quickly explained in detail.

"That's it~"

Liu Jin smiled and nodded.

When I came to the laboratory, I took a closer look at their device. It was very simple and not complicated at all.

"This is a power generation device. We found that cutting a magnetic field can generate electricity, and electricity can also generate magnetism. Then we developed a generator. By stepping on a bicycle, a person can continuously rotate the device on it to generate a steady stream of electricity. Constant current."

"This is the transmitter of the electromagnetic signal. After the current passes through here, it can continuously emit electromagnetic waves into the air, and then there will be a similar electromagnetic wave receiver at the other end. When the electromagnetic wave is propagating, it can receive the electromagnetic wave, and finally form a Effective information delivery."

Lai Ji introduced it in detail. This device looks simple, but it is the most technologically advanced thing in this era.

It is also the result of many years of research on the side of the Ming Empire.

"Let's start then~"

Liu Jin listened carefully, and based on the information in his mind from the later generations, he found that although this device was simple, it was no different from the telegrams of later generations.

"Yes~"

Lai Jilian nodded, and then gave orders.

Soon, a strong student began to step on the power generation device continuously. As the power generation device started to generate electricity, the electromagnetic launcher began to continuously generate electromagnetic waves.

Of course, this kind of electromagnetism cannot be seen at all.

After a little adjustment, a dedicated student began to tap a button regularly, which made Liu Jin think of the plots he had seen in later movies.

Didi, Didi, Didi's voices were very rhythmic. Everyone held their breath, watching quietly, and at the same time quietly waiting for Zhu Houzhao's response from Huairou County.

On the other side, Zhu Houzhao's electromagnetic laboratory in Huairou County is here.

Zhu Houzhao is also excitedly staying in the laboratory at this moment. According to the time agreed by both parties, it is almost about to start now.

"DiDi~DiDi~"

Zhu Houzhao didn't wait too long, and regular voices came from the receiver.

"Haha, here we come~"

Zhu Houzhao immediately laughed happily.

"Huairou, Huairou, I am here from Imperial College~"

"Please answer if you receive it~ Please reply if you receive it~"

Looking at the translated information, Zhu Houzhao couldn't help pouting, it's official.

After thinking about it, he personally operated the transmitter, and soon a set of messages was sent out.

The lab at Imperial College here.

Liu Jin and others were waiting patiently, waiting for the information from Zhu Houzhao.

It didn't take long for the receiver to respond.

The people in the laboratory quickly translated the information.

"Lao Liu, Lao Liu, I am Lao Zhu~"

When the translator translated the information, Liu Jin immediately knew that this must be Zhu Houzhao, and he was the only one who could be so casual.

"Ask him, how many sons he has now~"

Liu Jin smiled, thought for a while and said.

Soon, a group of information was quickly sent out through electromagnetic waves.

"How many sons?"

"Haha, it really is Old Liu~"

Zhu Houzhao laughed happily when he received the message.

"Old Liu, I have already given birth to forty-five sons, you have to work hard~"

"..."

Liu Jin was speechless immediately, this guy has completely become a big pig now~
