The telegraph designed by Ang Lee, using Morse code, is also a relatively simple technology, so it is not so difficult to develop, and it has almost succeeded in only a few months.

The so-called Morse code is just a use of two different situations of power-on and power-off to define all the letters, and Ang Lee replaced the letters with strokes, and the effect is the same, and it can also perfectly use the circuit to transmit information.

According to the official interpretation of later generations, Morse cipher is a time-on and intermittent signal code, which expresses different letters, numbers and punctuation marks through different permutation orders, and is an early form of digital communication, but it is different from the modern binary code that only uses zero and one or two states, and its code includes five kinds, dots, strokes, pauses between dots and strokes, medium pauses between each word, and long pauses between sentences.

Morse code played an important role in early radio and was a must-know for every radio communicator. Due to the progress of communication technology, it was later abolished, but because it occupies the least bandwidth, and has a technical and artistic characteristics, it has a wide range of applications in practical life.

Although Morse invented the telegraph, he lacked the relevant expertise. He made a deal with a friend to help him build more practical equipment. His friend conceived a scheme where, through dots, strokes, and pauses in between, each character and punctuation mark could be sent independently of each other. They agreed to put this scheme of identifying different symbols into Morse's patent, which was used to transmit the world's first telegraph.

This code can be transmitted by a steady, intermittent radio signal, often called a continuous wave, which can be an electrical pulse in a telegraph wire, or a mechanical or visual signal.

Generally speaking, any encoding method that can represent written characters in a signal of variable length can be called Morse code, but later the term was only used to refer to two types of Morse code that represented English letters and symbols, the American Morse code was used in the cable telegraph communication system, and the international Morse code still used in later generations only used dots and strokes.

The telegraph company charged according to the length of the letter to be sent, and the commercial code carefully designed a code of five characters to be sent as a single word.

As a virtually extinct form of code, the American Morse code uses disparate dots, strokes, and unique spacing to represent numbers, characters, and special symbols. This Morse code was designed primarily for terrestrial telegraph operators to transmit over telegraph wires, not over radio waves.

This ancient, interlaced code was designed to match the way the telegraph operator answered. Unlike today, where you can hear the tone of the code from speakers or headphones, you can only hear the clicking sound from a mechanical generator in these earliest telegraphs, or even from the transmitting key, which was set to passive mode when not sending a signal and was responsible for making sounds.

Most of these operators were for the railroad or later for Western Union telex, etc. Like many young people at that time, Edison was one such operator.

Ang Lee is very familiar with the Morse code, however, most people in later generations have a lot of understanding of the Morse code, most of which comes from film and television dramas.

However, in Ang Lee's opinion, this is too difficult, because the Morse code needs to be typed many times to confirm a word, how can the human brain react so quickly, just a light glance at others knocking on the Morse code, you can immediately understand the specific content, however, if the content of the knock is very small, only a small number of words, it can be completely reflected.

"It's that the coil is not done well here, and the contact is a little bad, this problem must be paid attention to, okay, try again."

Ang Lee slightly changed the machine, and then asked everyone to continue the experiment, and continued to send messages to another room, where there was a person who specialized in receiving telegrams, and would answer the contents of the telegrams after receiving the contents of the telegrams, and then send them back.

The distance between the two experimental rooms is about 300 paces, so even if you shout loudly, the other room will not hear the news, which can eliminate the possibility of fraud.

"Didi Di Di ......"

Listening to the sound of the telegram being sent, Li An's heart was both excited and nervous, this was the critical moment of the experiment, and Li An was not completely sure whether he could prepare to pass the news over.

"Li Shilang, the villain has already sent it, and the content is to let Li Craftsman come quickly."

The technician who sent the telegram spoke.

"Li Shilang, the other party replied, saying that Craftsman Li has set off and will arrive soon."

Another technician, he said.

Hearing this, many people in the room became excited, they had fully understood the principle of Morse code after Ang Lee's many teachings, so they naturally knew what was going on, how could they not be excited, this was the result of their hard work in the past few months.

"Li Shilang, the villain is here, here."

Li Jiangren, who was in his thirties, ran over panting and bent down to salute Li An.

"Li Shilang, it seems that our experiment has finally succeeded, can we report the good news to Your Majesty."

A craftsman who usually almost never smiles is also a little unable to control his smile at the moment, and the corners of his mouth frequently show happy smiles.

"Don't be in a hurry, you continue the experiment, by the way, it's already past the meal, everyone is divided into two groups to eat, the experiment can't be stopped for a moment, you must verify the reliability of the machine, you can't just break it casually!"

Li An arranged very cautiously.

Not to mention the machine he made at the moment, even if it is a very expensive advanced electronic instrument in later generations, there will be all kinds of problems, and some problems can not even find the reason, no one can figure out what is going on, and once there is an inexplicable problem, not only delay the use, but even at a critical time, it will delay the big thing, so stability is the top priority of electronic instruments, even if the performance is slightly worse, it doesn't matter much.

It is precisely because people are pursuing stability, so, in later generations, many brand goods are the worst configuration, but there are still many people rushing to buy worse configuration with the same money, which seems to be quite stupid, but many people are willing to do this, the reason is because the brand configuration is relatively poor, the performance does not seem to be very good, but the technology is mature, the stability is the highest, and the after-sales service is very guaranteed, and many products with better performance are because the technology is not mature enough. There may be a variety of failures when using, and once there is a failure, you will not be able to deal with it, and you will not be able to find anyone after the sale, so it will bring great trouble to your life.

The pursuit of stability is the traditional thinking of the entire Chinese nation, it has been the case since ancient times, the common people want to live a stable life, businessmen also want to make money steadily, and the state cadres are also busy maintaining social stability.

Therefore, stability is very important in all aspects, no matter what product, if the stability is insufficient, the value will be greatly reduced, and the telegraph is no exception, and it is even more important.

If you want to verify whether an electronic product has stable performance, the most reliable way is to keep using it to see how durable the product is, how long it can be used continuously, if it is used for a long time without failure, then the product is reliable, if it is used for a while, there is no way to use it, and the reason must be re-found to increase the durability of the product.

Ang Lee's stomach was really hungry, so the first batch went to eat, but half of the technical talents had to stay to continue the experiment, and the remaining half ate with Ang Lee.

In order to reflect the importance of these technical talents, in the R & D center, a number of canteens have been built, the specifications of these canteens are very high, the internal facilities are also very good, more luxurious than the big restaurants outside, and the winter is not cold, the summer will not be very hot, the quality of the meals is also very guaranteed, everyone can get four dishes and one soup treatment, however, the use of a special fast food box, so, it will be more convenient to use, if you use ordinary dishes, then you need four plates and two bowls, If you use a fast food box, you only need to add another soup bowl.

Although Ang Lee's status is very high, in order to reflect his attitude of sharing weal and woe with the craftsmen, he did not prepare dishes alone, but ate the same fast food as everyone else, but the portion was more sufficient, and the chef who served the rice gave Ang Lee the best meals.

In fact, Li Ang does not eat with the craftsmen every time, most of the time, Li Ang will eat his own small stove, after all, there is still a certain gap between the taste of the big pot of rice and the small stove, and the types of dishes are relatively less, and it is too aggrieved to eat a big pot of rice often.

People are in good spirits when they are happy, and when they encounter happy things, their mood is naturally very good, and the results of the experiment just now make Li Ang very satisfied, so when he eats, he is also very happy, and he feels that every dish is so delicious, so that Li An suddenly feels that the taste of this big pot of rice is actually several times better than usual.

Of course, being in a good mood is one thing, and on the other hand, Li Ang missed the noon meal, and he was even more hungry than usual, so it was naturally more delicious to eat.

"Today's food is extraordinarily delicious, and the cooks have to remember it, and they all have a reward, and it is a great reward, and the number of rewards has been tripled."

Li An was so happy that after just a few bites, he couldn't wait to announce that he was going to reward the cook.

The cooks were puzzled when they heard this, the food they cooked today was not much different from usual, it could be said that it was exactly the same, but they could get a great reward, which naturally made them feel strange.

"Thank you Li Shilang, thank you Li Shilang."

The head of the cook was overjoyed, smiling with chrysanthemums all over his face, and there was nothing more than a reward, more than a reward of money.

However, the craftsmen who were eating were a little anxious, their credit was much greater than that of these cooks, as soon as Li An opened his mouth, he gave the chefs three times the reward, but did not mention the reward, which naturally made them feel very unhappy, although they knew that Li An would not fail to reward them, but the eagerness of the mood made them unwilling to wait longer, and they wished that they could get the promise immediately, and let them be happy and happy as soon as possible.

"Li Shilang, what about us? We have worked hard for several months, and there is no merit and hard work! ”

"Yes! Oh, yes! The success of today's experiment is all the work of Li Shilang, but we have also done our best, and we also have a hard work in it! ”

"Oops! What are you anxious about, Li Shilang hasn't thought of what to reward for us? ”

Many craftsmen said in a gossiping voice, but everyone's expressions were relatively happy, they were all very confident, knowing that Li An would definitely reward them, and the amount would not be more than what these cooks would get.

Li An naturally did not disappoint the craftsmen, stopped his chopsticks, and said, "As long as the Wanli Transsin plan is completed well, are you still worried about the reward?" Eat, eat well, this official will never treat you badly, haha! ”

"Alright, let's eat! If there is a reward, why rush for a while, haha! ”

"Yes! I believe that we will be rewarded more than these cooks. ”

"If Your Majesty knows this good news, he will give us more rewards!"

All the craftsmen were excited about the reward, and the joy of success hung on everyone's face.

"Look at your little bit of talent, hehe!"

Li An scolded with a smile, and after eating quickly, he had to rush back to the laboratory to continue to improve the newly developed machine to ensure absolute reliability.

The telegraph did not last long to be used once, so as long as it could be used continuously and stably for an hour, the experiment could be regarded as a success, and it would be necessary to improve it in the future.

Because it is the first research and development, therefore, all kinds of parts are relatively large, the whole machine is made more than ten times larger than the telegraph in memory, and the total weight is two or three people can lift, however, because there is no complete box, each component is scattered, unplug the connecting wire and disperse the transportation can be, after transporting to the place where it is needed, and then put the wire on the face.

However, this kind of telegraph machine full of parts is too unfashionable to look at the eyesore, and many of these parts can be optimized and installed in a box, so that it looks much more concise and clear.
