The carpenters that Win Changsheng needed were called over after a while, and when these carpenters were called.

Ying Changsheng directly ordered them to start making something.

Things are not difficult to make, they are nothing more than a few simple wooden workpieces, but the requirements of Ying Changsheng are extremely fine, and the standards required are extremely high.

Among them, the most important thing is a wooden shell, and a hole is reserved in the wooden shell, which can just be installed and installed on a thing.

This thing is nothing else, it is an electromagnet.

In addition to reserving the position for installing the electromagnet, Ying Changsheng also reserved a position on it.

On the top of the electromagnet, the craftsman is required to make a long switch, the upper part of the switch is made of wood, one side of the wooden strip is cocked on the other side when the tension spring is used, and the other side is cocked on the lower side of the iron block, facing the electromagnet.

On the side of the side, there is a switch, which is the switch that is energized, and the energized switch is also pressed, and the power is energized when pressed, and then the power is automatically cut off when it is released.

Ying Changsheng asked the woodworking to make such a simple mechanical structure, which was relatively simple to make, and in just two days, after several experiments, such a simple machine was successfully made.

Look at this delicate wooden box in your hand.

Ying Changsheng nodded with satisfaction, and then instructed the craftsman to make two.

After the two wooden boxes were made, Ying Changsheng ordered the craftsman to build a transformer into them, so that after insulating all the objects, Ying Changsheng decided to experiment with this.

Test whether this simple and rudimentary telegraph can work properly.

Outside the Xianyang Palace at this moment.

Along the interior of the workshop.

Reach the outside of the workshop in the distance until you reach the city gate.

There is a distance of five or six miles, and a wire has been laid at this moment, and after the wire is properly laid, Ying Changsheng instructed the public to go to the other end of the wire to guard and guard the telegraph, while he personally operated the telegraph in the workshop.

Follow pre-set rules.

He had to press the button that sent the report three times in a row.

After pressing that button.

On Ying Changsheng's side, after receiving the news, Ying Changsheng will reply to him with three long and one short.

Now.

Sitting in the city gate, there were soldiers guarding on the side, and he hesitated for a moment, and then pressed it, pressed the switch that was energized, and at the moment when the switch was energized.

The male loses and then loosens.

Then press it again, and release it again.

Three times in a row.

After doing this, under the transmission of electricity, he won Changsheng's side in an instant.

Da-da-da-da.

There were three sounds in the air, the crisp sound of iron pieces striking.

The tapping sound came from a telegraph machine.

It is the iron piece that the electromagnet sucks on it after generating a magnetic force, and it is controlled by the tension spring, and the iron piece that is usually at a distance from it is usually at a distance, and then emits a crisp impact sound.

And after the electricity, completely cut off.

Under the action of the tension spring, the iron sheet will once again move away from the electromagnet.

And then.

As the power comes on again.

The electromagnet starts up again.

In this way, it is possible to make another sound from the impact, and at this moment the three sounds are heard.

Ying Changsheng immediately reacted.

He hurriedly agreed in advance, three long and one short.

Then he sent a message to the public to send a message.

At the moment of receiving this message.

When I heard that, the three long and one short sounds produced by the impact of the electromagnet made three sounds, and for a while, my eyes suddenly lit up.

He certainly knew what that meant.

Of course, he knew that this meant that the Great Qin Empire had a way to quickly transmit information from now on.

Although this method of transmitting information is very backward, even so, it is possible to pass some agreements and then pass some simple messages.

Then he rode a fast horse and hurried back to Win Changsheng.

Report to Ying Changsheng.

"Nineteen sons, this telegraph machine is indeed available, we only need to agree on some, agree on some rules for transmitting information, agree on some, press the switch a few times, what kind of news is transmitted, and it can be used to transmit information up and down my Daqin!"

"Who told you to make such a rule? This son wants to make a code table, and through this telegraph, detailed information can be transmitted, accurate to the numbers, accurate to everything! ”

"How is this possible?"

Win Changsheng's voice fell for a while, and the public on the side couldn't help but let out an exclamation.

"How is this impossible? It's entirely possible! ”

Ying Changsheng said with a smile.

It's really possible that he has already figured out how to do it.

Here's how it works.

Make a coder.

In the early days of history, the telegraph was the same principle as the telegraph made by Ying Changsheng today, but how did they convey detailed information with a simple impact sound?

The answer is simple, a kind of code that they made.

This code is called Morse code.

At this time, Ying Changsheng planned to make this thing.

I saw him smiling and opening his mouth to say.

"Leave this matter to Ben Gongzi, Ben Gongzi will go back and make a comparison code table, so that the information can be transmitted through this telegram!"

Comparison Table.

Win longevity.

It's been thought about.

It's nothing more than putting a string of codes on every word.

It's actually quite simple.

Of course, there are also some detailed considerations, such as how to arrange the code so that people can master it in the shortest possible time.

At the moment, after thinking about it.

Ying Changsheng directly took a dictionary compiled by the Great Qin official, and then through this dictionary, each word was encoded word by word, and he personally operated the telegraph.

First, the code of the telegraph was regulated.

To sum up, the whole twenty-five codes, twenty-five codes are respectively, respectively, composed of different tapping frequencies.

The length of time to tap is determined.

It is the length of time that the electromagnet is energized.

Of course, from one to twenty-five, this is too long.

Therefore, Ying Changsheng stipulates that two taps are used as a code signal, so that the time can be greatly shortened and shortened.

Then, it began to win the copy mode of immortality.

Twenty-five codes, the reason why this way is used is purely because Ying Changsheng knows a kind of electronic code meter that can be directly copied.

This thing is the famous five-stroke input method in later generations.

With twenty-five codes, you can use this thing smoothly.

Directly follow the five-stroke comparison table, and then, replace one word with several codes.

Easily won Changsheng, and in just two days, he compiled a telegram code that can be used for practical operation.

I have to say, this is really fast!
