Valley Emperor

He Shengzhong pointed to a number of huge mechanical equipment placed on the table and said, "Your Majesty, this is the radio transmitter unit we developed!"

Then he pointed to several mechanical devices on the other side and said, "This is our radio receiver unit!"

After speaking, he also stepped forward to test the operation in person: "Like wired telegraphy, we convert the text into codes, and then send the encoded signals through this transmitter!"

"The signal will be propagated through electromagnetic waves, and the receiver will receive the electromagnetic signal and then convert it into an information code. After interpretation, the message can be obtained!"

"A large part of the principle of the whole system is connected with the wired telegraph. The only difference is the signal transmission channel. We use electromagnetic waves to directly replace electrical signals!"

Li Xuan looked at the two huge units in front of him, inexplicably reminded him of the primitive computers of later generations, which seemed to be super huge.

He can understand why it is so huge, it is nothing more than that the technology is not enough, but it has to come up with wireless telegraphy.

However, the size is not important. This is just the first-generation test prototype. As long as the basic design principles are worked out and can be built, the follow-up will naturally be able to continue to develop, thereby reducing the size and weight.

What's more, the size of the body is huge now, and it is only relative to the later generations. For this era, the weight of a few hundred kilograms is a fart!

Even if this thing is used now, it is fixed in a certain place, or simply installed on the battleship. It doesn't matter if it is a few hundred kilograms or even a few thousand kilograms. The key is to be able to use it.

So he asked directly: "You have already tested it before, what is the result? How far can the signal travel?"

He Shengzhong said: "When we conducted the test before, the test was successful. We successfully launched the electromagnetic model and received it by the receiver. The next step will be to conduct a distance test. According to our calculations, now The information transmission distance of this prototype can reach at least 20 kilometers, or even further, but the specific distance depends on the terrain."

"After all, the earth is round, and the process of signal transmission will be greatly affected by curvature and terrain, resulting in the constant weakening of the signal!"

"However, we already knew that the atmosphere can reflect electromagnetic waves. At present, we are conducting research on the electromagnetic wave reflection phenomenon in the atmosphere to determine the wavelength of electromagnetic waves, and finally conduct ultra-long-distance signal transmission experiments!"

"However, in specific circumstances, it is necessary to wait for the relevant tests to be completed before the next generation of wireless telegraphs can be manufactured for related tests."

Li Xuan nodded slightly after listening. The wireless telegraph has just been developed. It is already very good to be able to transmit signals. You can't expect it to be able to transmit transoceanic signals all at once.

And the technological leap of this thing is not big, as long as you start, then the follow-up is simple!

Li Xuan said immediately: "Can this machine test one or two now?"

He Shengzhong said: "Yes, we also have the same signal receiver in the laboratory in the east of the academy, which can send signals directly!"

Li Xuan said: "Then give it a try!"

As he said that, he also pointed to a group of civil and military officials behind him and said, "They are all waiting to see!"

The importance of wireless telegraphy is known to everyone present, regardless of whether they are cabinet officials or those generals, all of them are eagerly looking forward to wireless telegraphy.

Because the important ministers of the empire believed that a communication system such as a wireless telegraph could effectively strengthen the empire's rule over global territories and further curb the possibility of mutiny in overseas territories.

The timely and smooth transmission of information has always been the great importance of the Tang Dynasty, and it is even the basis of the rule of the Tang Dynasty.

This is not unique to the Tang Dynasty. In fact, the Huaxia Dynasty has always attached great importance to the transmission of information.

The previous dynasties engaged in the post station system is the most typical example!

The Datang Empire used to vigorously develop the post system. Every day, countless post post horses galloped on the road to pass various military official documents. Later, the navy also specially developed a clipper ship to act as a communication ship.

Later, after the emergence of high-pressure steam engines, trains appeared, and steam ships came out, so the corresponding trains and steam ships also became the main means of information transmission.

Even now, many trains serve as the mission of postal trains. In addition to transporting passengers and goods, trains also transport a large number of letters simultaneously.

The navy has also simultaneously developed a fast communication ship using steam engines, which is so fast that it can transmit information to and from the seas around the world.

Later, after the invention of the wired telegraph, the Datang Telegraph Company was established in an instant, and within a few years, the telegraph line was erected along the railway line.

Immediately, Datang entered the telegraph era.

What happened in the place with the telegram, the place with the telegram on the other side would soon know.

This shows that the Tang Empire attached great importance to communication.

And now the wireless telegraph can make the communication system of the Tang Empire further~www.wuxiaspot.com~ more perfect, these imperial officials naturally attach great importance to it.

It doesn't matter whether they attach importance to science or not, they simply attach importance to the speed of information transmission and the rule of the empire.

Li Xuan ordered the test, and the Royal Institute of Technology has already prepared it well. Today's inspection originally included the test.

After some preparations, He Shengzhong stepped forward and said, "Your Majesty, you are ready!"

Li Xuan said: "Then let's start!"

He Shengzhong said, "What's the content?"

Li Xuan said: "If you want, just post today's date!"

It doesn't matter what the content is, the important thing is that it can be sent and received!

Soon, the researchers on the telegraph began to work, but the operation seemed to be very simple, and it was no different from the ordinary wired telegraph transmission. It was a telegraph operator who was there dripping the button!

After pressing the button, He Shengzhong stepped forward and said, "Your Majesty, the signal has been sent!"

Li Xuan nodded slightly. After the signal was sent, another receiver in the laboratory also received the signal.

The wireless telegraph receiver was already working, and soon the telegram was translated with the date it was sent.

But people waited, they waited for information from the receiver in the laboratory a kilometer away.

It didn't take long for the sound of horses' hooves to be heard outside, and soon a telecommunications secretary of the Hanlin Academy dismounted, and then presented a telegram to Li Xuan, and said at the same time: "Your Majesty, this is the telegram accepted by the minister!"

Li Xuan took it over and saw that it was the telegram he had sent out, "November 16, 40 years of Xuanping."
