Ang Lee's design of the telegraph used Morse code, which was a relatively simple technology, so it was not that difficult to develop. In just a few months, it was almost successful.
The so-called Morse code, on the other hand, used two different situations, power on and power off, to define all the letters. Ang Lee replaced the letters with strokes, and the effect was the same. It could also perfectly use the circuit to transmit information.
According to later official explanations, Morse code was a signal code that was on and off. It used different sequences to express different letters, numbers, and punctuation. It was an early form of digital communication, but it was different from modern binary codes that used only zero and one or two states. Its code consisted of five types: dots, dashes, pauses between dots and dashes, medium pauses between each word, and long pauses between sentences.
Morse code was important in the early days of radio, and every radio communicator had to know it. Due to advances in communication technology, it was later abolished, but because it occupied the least bandwidth and had a technical and artistic character, it was widely used in practical life.
Although Morse invented the telegraph, he lacked the relevant expertise. He made an agreement with a friend to help him build a more practical device. His friend conceived a scheme that used dots, dashes, and pauses in between to allow each character and punctuation to be sent independently of each other. They agreed to put this scheme of identifying different symbols in Morse's patent, and it was used to send the world's first telegram.
This code can be transmitted by means of a steady, intermittent radio signal, usually called a continuous wave, which can be either an electrical pulse in a telegraph wire or a mechanical or visual signal.
Generally speaking, any code that could represent written characters in a variable-length signal could be called Morse code, but later this term was only used to refer to the two Morse codes that represented English letters and symbols. American Morse code was used in the cable telegraph system, while the international Morse code, still in use in later years, only used dots and dashes.
Telegraph companies charged according to the length of the letter to be sent, and commercial codes were carefully designed to form groups of five characters and sent as a single word.
As a virtually extinct code, American Morse code used different dots, dashes, and unique intervals to represent numbers, characters, and special symbols. This Morse code was designed to be transmitted by telegraph operators on the ground over telegraph wires, rather than radio waves.
This ancient, interlaced code was designed to match the way telegraph operators received calls. Unlike today, where you can hear the tone of the code through speakers or headphones, you can only hear the ticking sound from a mechanical generator in these earliest telegraphs, or even from the transmit key, which is set to passive mode when not transmitting and is responsible for making sounds.
Most of these radio operators worked for the railroads and later for Western Union. Like many young men of that time, the future Edison was such a telephone operator.
Ang Lee was very familiar with Morse code, but most people's understanding of Morse code came from movies and TV dramas. In many spy movies, many people secretly used the Morse code on the table to transmit information, thus successfully transmitting the message.
However, in Ang Lee's opinion, this was too difficult, because Morse code needed to be typed many times to confirm a word. How could the human brain react so quickly? Just by looking at other people typing in Morse code, one could immediately understand the specific content. However, if the content of the typing was very small, and only a few words were typed, it was completely possible to react.
"The coil here is not done well, and there is a little bad contact. This problem must be paid attention to. Okay, try again."
Ang Lee slightly modified the machine, and then let everyone continue the experiment. They continued to send messages to the other room, where there was a person who specialized in receiving telegrams. After receiving the contents of the telegram, he would reply to the contents of the telegram, and then send it back.
The distance between the two experimental rooms was about three hundred steps. Therefore, even if one shouted loudly, the other room would not hear the message, eliminating the possibility of fraud.
Beep beep beep beep …
Listening to the sound of the telegram being sent, Ang Lee was excited and nervous. This was the critical moment of the experiment, and Ang Lee was not completely sure if he could send the message properly.
"Assistant Minister Li, I have sent it. The content is for Craftsman Li to come quickly."
The technician who sent the telegram said.
"Assistant Minister Li, the other side replied that Craftsman Li has set off and will be here soon."
Another technician said.
Hearing this, many people in the room became excited. After many lessons from Ang Lee, they had completely understood the principles of Morse code, 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.
"Assistant Minister Li, I'm here, I'm here."
Craftsman Li, who was in his thirties, ran over, panting, and bowed to Ang Lee.
"Assistant Minister Li, it seems that our experiment has finally succeeded. Can we report the good news to His Majesty?"
A craftsman who rarely smiled could not control his smile at this moment, and the corners of his mouth curled up into a happy smile.
"No need to rush, continue the experiment. Oh right, it's already past mealtime. Everyone, eat in two groups. The experiment must not be stopped for a moment. We must verify the reliability of the machine. We can't let it break down casually!"
Ang Lee made arrangements very carefully.
Not to mention the machine he made now, even the very expensive and advanced electronic instruments in the future would have all kinds of problems. Some of the problems could not be found, and no one could figure out what was going on. Once an inexplicable problem appeared, not only would it delay the use of the machine, but it would also delay important matters at critical times. Therefore, stability was the most important thing in electronic instruments. Even if the performance was slightly worse, it was not a big deal.
It was precisely because people pursued stability that, in the later generations, many brands' products had the worst configuration. However, many people still flocked to them and used the same amount of money to buy a worse configuration. It seemed quite silly, but many people were willing to do so. The reason was that although the brand's configuration was worse and the performance did not seem to be very good, it was valuable because the technology was mature and the stability was the highest. The after-sales service was also very guaranteed. On the other hand, many products with better performance might have all kinds of malfunctions during use because the technology was not mature enough. Once a malfunction occurred, they would not know how to deal with it, and they would not be able to find someone to help them after the sales service. As such, it would bring a lot of trouble to their lives.
The pursuit of stability was the traditional thinking of the entire Hua Xia people. It had been so since ancient times. The common people wanted to live a stable life, the businessmen wanted to make money steadily, and the government officials were busy maintaining the stability of the society. Only stability could make people feel at ease. Many women even liked to marry men with stable jobs for the sake of peace of mind.
Therefore, stability was very important in all aspects. No matter what product, if it was not stable enough, the value would be greatly reduced. The telegraph was naturally no exception, and it was even more important.
If you want to verify whether an electronic product has stable performance, the most reliable way is to use it continuously to see how durable the product is and how long it can be used continuously. If there is no malfunction after using it for a long time, then the product is reliable. If there is a malfunction after using it for a while, then there is no way to use it anymore. You have to find the reason again to increase the durability of the product.
Li An's stomach was really hungry, so the first batch went to eat. As for the technical talents, half of them stayed behind to continue the experiment, and the other half followed Li An to eat.
In order to show the importance of these technical talents, many canteens were built in the R&D Center. The specifications of these canteens were very high, and the internal facilities were also very good. They were more luxurious than the big restaurants outside. Moreover, it was not cold in winter, and it was not very hot in summer. The quality of the food was also very guaranteed. Everyone could have four dishes and one soup. However, they used a special fast food box, so it was more convenient when using it. If they used ordinary bowls and plates, they would need four plates and two bowls. If they used a fast food box, they only needed to add another soup bowl.
Although Li An's status was very high, in order to show that he was willing to share the joys and sorrows of the craftsmen, he did not prepare individual dishes. Instead, he ate the same fast food as everyone else, except that the portion was bigger. The chef who was in charge of the food gave the best dishes to Li An.
In fact, Ang Lee did not eat with the craftsmen every time. Most of the time, Ang Lee would eat his own special stove. After all, the taste of the big pot of rice was still a certain gap compared to the special stove. Moreover, the variety of dishes was relatively fewer. It was too unfair for Ang Lee to eat the big pot of rice often.
People were in high spirits when they encountered happy things. When they encountered happy things, their mood was naturally very good. The results of the experiment just now made Ang Lee very satisfied, so when he ate, his mood was particularly happy. He felt that every dish was so delicious. As a result, Ang Lee suddenly felt that the taste of this big pot of rice was actually several times better than usual.
Of course, the good mood was one reason. Another reason was that Ang Lee missed lunch, so he was hungrier than usual. Therefore, the food was naturally more delicious.
"Today's food is particularly delicious. All the chefs have to record this merit and will be rewarded. Moreover, it is a big reward. The amount of reward will be increased by three times."
Ang Lee was so happy. After eating a few mouthfuls, he couldn't wait to announce that he would reward the chefs.
The chefs were very puzzled when they heard it. 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 big reward. Naturally, they felt strange.
"Thank you Assistant Minister Li, thank you Assistant Minister Li."
The head chef was so happy that his face was full of chrysanthemum flowers. Nothing could make people happier than a reward, more than a reward of money.
However, the craftsmen who were eating were a little anxious. Their merit was much greater than these chefs. Ang Lee opened his mouth and gave the chefs three times the reward, but did not mention anything about rewarding them. This naturally made them feel very unhappy. Although they knew that Ang Lee would not not reward them, their eagerness made them unwilling to wait any longer. They couldn't wait to get the promise immediately so that they could be happy earlier.
"Assistant Minister Li, what about us? We worked hard for a few months. Even if we didn't get any merit, we should at least get some credit for our hard work! "
"Yes! Yes! The success of today's experiment is all thanks to Assistant Minister Li, but we also did our best. We should also get some credit for our hard work! "
"Aiya! Why are you guys in such a hurry? Assistant Minister Li hasn't thought of what to reward us with yet. "
The craftsmen were all talking at once. However, everyone looked happy. They were very confident and knew that Ang Lee would definitely reward them. Moreover, the reward would not be more than what the chefs received.
Ang Lee naturally would not disappoint the craftsmen. He put down his chopsticks and said, "As long as we complete the Thousand Mile Telepathy Project well, why are you guys still worried about the reward? Eat, eat properly. This official will definitely not treat you guys unfairly, haha! "
"Alright, everyone, let's eat! As long as there's a reward, there's no need to rush, haha! "
"Yes! I believe that the reward for us will definitely be more than what the chefs received. "
"If His Majesty knows about this good news, he will probably reward us even more!"
The craftsmen excitedly thought about the reward. The joy of success hung on their faces.
"Look at you guys, haha!"
Ang Lee jokingly scolded them. After the meal, he quickly ate. He still had to rush back to the laboratory to continue perfecting the newly developed machine to ensure its absolute reliability.
The telegraph could only be used for a short period of time. Therefore, as long as it could be used continuously for two hours, the experiment could be considered a success. He just had to perfect it in the future.
As this was the first time it was developed, the various parts were relatively large. The entire machine was more than ten times larger than the telegraph machine in his memory. The total weight could only be lifted by two to three people. However, as it did not have a complete box, the various parts were scattered. They just had to unplug the connecting wires and transport them separately. After they were transported to the place where they were needed, they just had to connect the wires.
However, this kind of telegraph machine with spare parts everywhere was too unfashionable. It was an eyesore to look at. Many of the spare parts could be optimized and put into a box. This way, it looked much simpler and clearer.
