Chen, who had been exposed to telegraph knowledge for less than two hours, claimed that there was a way to improve the telegraph line. Yuwen Wen did not take it seriously at all. He did not think that Chen, a scientific illiterate person, could come up with any solution.

However, he did not want to discourage Chen's enthusiasm. After all, he did this little "popular science" to increase communication between husband and wife (concubine), and a question and answer or discuss a certain issue together is one of the ways to enhance the relationship between husband and wife (concubine).

"Okay, listen carefully to your husband and see what the new idea is good."

Yuwen Wen said with a smile, hiding contempt in his heart. Seeing his husband's expression of encouragement, Chen nodded vigorously, pondered for a moment, and expressed what he thought by chance in his heart.

"A telegraph model can be regarded as a complete telegraph line, right?"

Yuwen Wen nodded: "Yes."

"Then, three telegram models can be regarded as three complete telegram lines...and then, connect them to the end...that's it..."

Chen connected the three models to the end, connected them into a straight line, and then began to explain.

This is the models A, B, C, and are connected together.

The receiving end of Model A (electromagnet) is close to the transmitter end of Model B (the switch of the switch, that is, the electric key), while the receiving end of Model B (the electromagnet) is close to the transmitter end of Model C (the switch of the switch, that is, the electric key).

According to the existing telegram line relay mode, it can be assumed that there are two telegram transceivers, located at the connection between Model A and Model B, Model B and Model C. Here, it is the actual "telegram transit" station.

The first job of the transceiver is to receive the telegram from the electromagnet of Model A (Line A) and then use the switch of Model B (Line B) to transmit the telegram, and the same is true for the second transceiver.

When Yuwen Wen heard this, he nodded, and Chen mustered up the courage and continued to speak.

Then, the action of the armature on the electromagnet of Model A (receiving the newspaper end) is actually exactly the same as the action of the transmission end of Model B (restor switch). It is nothing more than one moves first and the other moves later.

This is the responsibility of the collector: receive the report (record the action of the armature of the electromagnet of Model A), and then send the report (reproduce the switch of the knife of the action model B).

So, since the principle of telegram is that the switch and the electromagnet armature operate simultaneously, why can't the electromagnet armature of Model A and the switch of Model B be synchronized?

"For example, add a battery circuit between Model A and Model B, use the armature of the former as the switch of the new circuit, and then add an electromagnet to the latter, that is, the switch of Model B's knife, so that it can also serve as the "armature". Wouldn't both sides be able to operate at the same time?"

"When the switch of Model A is closed, its electromagnetic is energized and the armature is sucked down. Then, as a switch of the new circuit, this armature connects the new circuit, so the switch of Model B, which is equipped with the electromagnet, is also closed."

"As soon as it is combined, the circuit of Model B is connected, so Model B's electromagnet works to suck the armature. Therefore, Model A's switch realizes the control of Model B's electromagnet armature, and there is no need for anyone to repeat it..."

"It's still a simple circuit composed of switches, electromagnets, and batteries, which can replace the receiver of the transit relay. The principle is very simple, right?"

When Yuwen Wen heard this, his eyes narrowed and he stared at the three connected models for a while.

Chen saw Yuwen Wen as if he was possessed by a demon, his eyes were dull and he felt a little uneasy. He was about to ask, but he saw Yuwen Wen pick up his pen and start drawing a "circuit diagram" on the white paper.

As he was drawing, Yuwen Wen shook his pen, pulled his hair with one hand, clenched his fists and beat his thighs with the other hand, and shouted in a low voice: "What a simple principle, I... why didn't I expect it!"

......

In the Patent Office, in the patent display laboratory, on the experimental table, a set of series circuits representing the two Beijing lines are ready.

At the table, Yuwen Wen and Chen were standing in casual clothes, and Lin Youdi and officials from the Patent Office were waiting on both sides.

Yuwen Wen looked at Chen and gave him an encouragement smile. Chen took a deep breath and began to introduce the patent she wanted to apply for: Dianyi Technology.

When the post station delivers official documents or messages, if the distance is too long, a horse will definitely not be able to withstand it and needs to be delivered relay: either the people and horses are replaced, or the horses are replaced but not the persons are replaced.

Similarly, if the telegraph line is regarded as a post road, then the "transfer stations" on the telegraph line are equivalent to the post road. Therefore, the current carrying the telegraph information is the horse riding by the post road.

For long-distance transmission of official documents, a horse has limited horsepower and needs to be replaced at the station halfway. Similarly, long-distance transmission of telegrams is transmitted because there is a resistance of the wire, which will attenuate the current intensity with the increase of distance, so it also needs to "swap" in the middle.

Take the two Beijing lines as an example. Although it is a long line that stretches for hundreds of miles as a whole, it is actually composed of "short lines" connected, which have telegram lines powered by independent battery packs.

The connection between "short-term" is the "transfer station".

In each transit station, there are transceivers and receivers on duty, recording the telegrams from one end of the line (such as Chang'an), and then sending the telegram content to the other end (Luoyang). The relays of "transit stations" can realize telegram communication from Chang'an to Luoyang.

Because of this, the transmission speed of the telegram is affected. If the transceiver and receiver in a transit station needs five minutes to conduct a "transit", the accumulated transit time of the transit station along the route will not be short.

Of course, this is much faster than the postman riding a horse to deliver messages.

The patent Chen wants to apply for is a switch device controlled by current rather than manpower. This switch replaces the transceiver and receiver and "automatically" "transfer" the telegram so that it can continue to be transmitted without delaying a minute or a second.

Its structure is very simple, it is a switch and electromagnetic circuit with its own battery.

Connect the device to the telegram line and connect the telegram lines at both ends. Once an electrical signal is transmitted from the "upstream" telegram line, the electromagnet (A) at the interface of the device will work and suck the armature (A) is sucked.

The armature (A) is the circuit switch inside the device. Once closed, the internal circuit inside the device is turned on, causing the electromagnet (B) at the outlet of the device to move and absorb the corresponding armature (B).

This armature (B) is a sending key for the "downstream" telegram line. Therefore, the electrical signal coming from "upstream" will automatically "transfer" to the next telegram line through this device powered by itself.

This device relays telegram signals like a station relay, so it is named "Dianyi".

After Chen finished the explanation, with Yu Wenwen's encouragement, he pinched the switch of the series circuit and used it as the sending key to start sending the report.

Ten connected "Dianyi" successfully "relayed" and successfully transmitted the telegram signal to the end of the closing end. As the electric keys rise and fall, the charcoal pen on the closing end also rises and falls simultaneously, leaving "points" and "scratches" on the rotating paper tape.

The technical principle demonstration was successful, Yuwen Wen was the first to applaud, and the others followed suit, Chen was extremely excited amid the tide of applause.

This is a different kind of glory. Chen was so excited that he didn't know where to put his hands. His cheeks flushed, and his already-sinking appearance of falling fish and geese seemed more and more charming.

She didn't expect that a sudden whim she had become a "patent", and her husband asked her to apply for this "patent" in her own name.

Officials from the Patent Office stepped forward to register the new patent and recorded the relevant information.

Yuwen Wen said to Chen with a smile: "This patent application is successful. Next, not only the two Beijing lines will be renovated, but several other telegram lines will also be modified. The telegram transmission speed instantly achieves synchronous delivery, which is amazing."

"Since you want to transform, you must use your patent technology. According to regulations, you have to pay the patent usage fee. It is not a small amount accumulated every year."

Chen Wenyan felt a little embarrassed: "I don't need this patent fee..."

"No, regulations are regulations, otherwise how can the patent system protect the rights and interests of inventors?" Yuwen Wen finished speaking, nodded to the officials of the Patent Office, and then took Chen Xiangwai to walk out.

The beloved concubine has "scientific research results" with high practical value, and it is time to apply for a patent and then enjoy the benefits of invention. Although the palace is not short of this amount of money, Yuwen Wen believes that it is a very meaningful thing for Chen.

His woman shouldn't be a beautiful vase that stands and only bows her head, lie down, and only spreads her legs. When he gets along with beauties, he shouldn't be "slap sex", but should do more meaningful things.

Now seeing Chen's extremely excited appearance, Yuwen Wen felt that it was very good.

The magical "Division Station" eliminates the transit transceiver and receiver, solves the problem of "delay" of long-distance telegraph signals, and improves the communication efficiency of telegraphs. It is gratifying, but it is not very helpful for breakthroughs in telegraph technology.

Telegrams are still in a "single-plank bridge". On the same telegram line, only one party can send reports and one party receives reports. Both sides cannot send and receive them at the same time. They are still point-to-point "communication".

So, everything is the same.

Yuwen Wen's helplessness was not reflected on his face. Because the patent certificate will take some time to complete, he did not plan to stay in the patent office and asked Chen: "It is rare to leave the palace today. Where do you want to see it?"

Chen actually wanted to go to the east and west markets, but the queen said that she should try not to let the emperor wander around the streets of the city to avoid accidents, so she shook her head: 'Your Majesty, let's go back to the palace.'

"That's it... Then go back to the palace."

Yuwen Wen and Chen boarded the car and drove back to the palace. They had just walked out not far, but Lin Youdi caught up from behind: 'Your Majesty! Your Majesty!'

Lin Youdi was a close minister of the emperor, so the guards did not knock Lin Youdi, who was running towards the imperial guards, but just politely separated him from the carriage. Yuwen Wen heard Lin Youdi shouting, so he stopped the carriage and ordered the guards to let Lin Youdi come over.

He opened the curtains and said to Lin Youdi, who had arrived by the side of the car: "Why are you so anxious?"

"Your Majesty, there are, there are new patents, and it's here! It's a new patent submitted by Yizhou and the branch office!"

Yuwen Wen smiled and said, "What kind of patent is that makes Lin Dajiang so anxious?"

Lin Youdi stuttered because of excessive excitement: "Your Majesty...Your Majesty! Yes, I applied for a telephone number and filed a patent!"
Chapter completed!
