Chapter 355 Sending a report
The carpenters that Ying Changsheng needed were called over in a short while, when these carpenters were called over.

Ying Changsheng directly ordered them to get up and start making something.

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

Among them, the most important thing is a wooden case. In the wooden case, a hole is reserved, which can be installed just right, and a thing can be installed on it.

This thing is none other than an electromagnet.

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

On the top of the electromagnet, the craftsman is required to make a strip-shaped switch. The upper part of the switch is made of wood. One side of the wooden strip is tilted up when the tension spring is used, and the other side is tilted up. Then install the iron block, facing the electromagnet.

On the side next to it, there is a switch installed, which is the switch for energizing. The switch for energizing also adopts a push type. When pressed, the power is turned on, and then the power is automatically turned off when it is released.

Ying Changsheng asked the carpenter to make such a simple mechanical structure. It was relatively simple to make. In just two days, after several experiments, such a simple machine was successfully made.

Look at this exquisite wooden box in your hand.

Ying Changsheng nodded with satisfaction and then ordered the craftsmen to make two.

After the two wooden boxes were finished, Ying Changsheng ordered the craftsman to build a transformer inside. In this way, after insulating all the objects, Ying Changsheng decided to experiment with this.

Test whether this simple and crude telegraph can work normally.

At this moment, outside Xianyang Palace.

Along the interior of the workshop.

Go all the way to the outside of the workshop in the distance to reach the city gate.

There was a distance of five or six miles, and a wire had already been laid. After the wire was laid, Ying Changsheng ordered Gongshu Shangzao to personally go to the other end of the wire to guard the telegraph machine, while he was working Bouchi personally operated the telegram.

Follow pre-set rules.

Gongshu Shangzao, he has to press the button for sending the report three times in a row.

After pressing that button.

On Ying Changsheng's side, after receiving the news, Ying Changsheng will write back to him.

now.

Sitting inside the city gate, surrounded by soldiers guarding him, Gongshu Shangzao hesitated for a moment, then pressed the power switch, the moment the switch was powered on.

Gongshu Shangzao, then let go.

Then press it again, then 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.

There were three sounds in the air, the crisp sound of iron plates hitting.

The knocking sound came from the telegraph.

It is the electromagnet that attracts it after generating magnetic force, controlled by the tension spring, and the iron piece that is usually a certain distance away from it, and then makes a crisp impact sound.

And after the electricity is completely cut off.

Under the action of the extension spring, the iron sheet will be away from the electromagnet again.

then.

With the electricity turned on again.

The electromagnet started up again.

In this way, the sound can be produced by another impact. At this moment, the three sounds are heard.

Ying Changsheng reacted immediately.

He quickly followed the pre-arranged agreement, three long and one short.

Then he sent the message to Gongshu Shangzao.

At the moment of receiving this information.

Hearing that, the three long and one short sounds produced by the impact of the electromagnet, for a moment Gongshu Shangzao, his eyes suddenly lit up.

Of course he 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 still possible to pass some agreements and then transmit some simple messages, only to see Gongshu Shangzao and give an order.

Then he hurried back to Ying Changsheng on his fast horse.

Report to Ying Changsheng.

"Young Master Nineteen, this telegraph is indeed available. We just need to agree on some rules for transmitting information, and agree on some. Press the switch a few times to transmit the message. Pass the message!"

"Who told you to formulate such a rule? I want to formulate a stopwatch, and I want to be able to transmit detailed information through this telegraph, accurate to numbers, accurate to everything!"

"How is this possible?"

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

"How is this impossible? It's completely possible!"

Ying Changsheng said with a smile.

It is indeed possible that he has already figured out how to operate this matter.

The way to do it is.

Make a code table.

In history, the early telegraphs used the same principle as the telegraphs produced by Ying Changsheng when they transmitted information, but how did they transmit detailed information with simple impact sounds?
The answer is simple, a code they created.

This code is called Morse code.

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

I saw him laughing and opening his mouth to say.

"Leave this matter to me. I will make a comparison table later. From now on, you can transmit information through this telegram!"

Check the code table.

Win longevity.

It has been considered.

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

This is actually very simple.

Of course, some detailed considerations are also required, such as how to arrange for people to master these codes in the shortest time.

At this moment, after thinking about it.

Ying Changsheng directly took a dictionary compiled by Daqin officials, and then through this dictionary, each word was encoded word by word. He personally operated the telegraph.

First, the codes of the telegraph were regulated.

Summed up, there are a total of 25 codes, and the 25 codes are composed of different tapping frequencies.

The duration of the tap is determined.

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

Of course, the wait from one to 25 is too long.

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

Then, the copy mode of Winning Changsheng began.

25 telegraph codes. The reason why this method was adopted was purely because Ying Changsheng knew an electronic code table that could be directly copied.

This thing is the famous Wubi input method in later generations.

With 25 codes, you can use this thing smoothly.

Directly follow the Wubi comparison table, and then replace a word with a few codes.

Ying Changsheng easily compiled a practical telegraph code in just two days.

I have to say, this is really fast!
