Chapter 188 The telegraph is almost ready for use
The construction of Weissenburg University has not stopped in the past three years. New buildings continue to expand along the lake, and many single-family villas have appeared in the mountains to the south. , that's where the professors live.
The lake in front of the university has begun to be called "University Lake", and no one uses the original name.
Heinrich resigned from the Royal Mage Corps last year and moved to Weissenburg University as a professor. He formed the "Lightning Academy" with his students and some colleagues to specialize in teaching and researching electrical magic.
Because Frederick gave him a large investment last year, there are a lot of students signing up for this college this year, and everyone is here to make a fortune in the future.
Under his example, the royal mage group was temporarily unsettled, especially the new mage who had just joined the group a few years ago and was still working through their seniority, and they also thought about changing jobs.
After all, the Royal Order of Mages is the strategic force of the Rhine League. Frederick did not want to poach people too much, so he asked them to form a mutual aid and co-construction unit with Weissenburg University. On the one hand, he allowed members of the Order of Mages who wanted to make money to come to the university. Teaching and conducting research, on the other hand, allowing students who are interested in joining the military to intern in the Mage Corps.
However, Frederick complained a lot about the royal mages. Last year, he promised 10,000 florins to let them make a gramophone that could be promoted. However, there is still no sign of it. I'm afraid he has to do it himself. Take action.
Frederick found Heinrich in a laboratory with red bricks and red tiles similar to a factory building. He first let Mingxiao wander around by himself, and then went in to see what they were doing.
More than a year after the launch of radio, Heinrich and the others have achieved some new results.
Several students are assembling an antenna. This kind of antenna has a circle of iron on the outside and filled with empty magic crystal powder in the middle. It is more than one meter long and as thick as chopsticks.
This type of antenna allows the transmitter to transmit the signal farther and allows the receiver to receive weaker signals.
In April this year, the Wesen Army supporting the Wesen Territory relied on a new wireless communication system to direct a company to divide into three groups at night to surround the enemy's camp, which was five times its size.
Ever since, Frederick had a big plan - to get the telegraph out.
However, in order to complete this plan, the equipment needs to be improved, which is Heinrich's current focus.
When Frederick arrived, Heinrich had just finished hand-making a magic array plug-in. This thing can be directly inserted into the magic array that sends signals like a graphics card, and its function is to determine the frequency of the signal.
"Principal," Heinrich raised his head and saw him and asked, "Is there something wrong?"
Frederick replied: "Nothing, I just came to take a look, you are busy. "
Seeing that he was fine, Heinrich went about his own business without saying a word, and began to invite my students to come over and do experiments.
Frederick didn't understand Morse code, so he made it up now. It's not difficult to make up a set of Rhine letters, Praian letters, numbers and punctuation marks.
There is a new set of equipment in the laboratory today. It is long like a box. Put the black paper tape through it. There are empty slots on the upper lid to put the letters. After arranging the contents, press the letters, and the corresponding words will be printed on the paper tape below. hole.
On the other side, the student wound up the clockwork of the paper feeding device, and the gear driven by the clockwork controlled a pair of rubber rollers to advance the paper tape.
The paper tape will pass through a device, the upper part of which will glow, and the lower part is a photosensitive magic resistor. The amount of magic elements passing through is proportional to the intensity of the light shining on it. The holes in the paper tape will pass through Time and will shine on it, and the signal sent out after the transmitter is turned on will be different.
Frederick watched quietly from the side as they sent out the words "The principal is watching!"
After about five minutes, there was movement at the receiver. The student immediately opened the paper tape feeding device there. The white paper tape had just been fed out half a palm in size. There were steel pins on the upper and lower sides of the paper tape. There were flashing electric sparks, leaving a string of black traces. The content was quickly translated, "Tribute to the Rector - in Nuremberg."
Frederick nodded with satisfaction, but there were still some problems. The received signal, whether it was "·" or "-", was relatively long.
“What’s going on?” He asked Heinrich. If this problem is not solved well, maybe “·” will become “-”, which will eventually lead to misunderstanding.
Heinrich replied: "The paper feeding speeds are different, some are fast and some are slow, and it is difficult to unify."
Frederick thought for a moment and used the escapement of the clock. It should be possible to control the rotation speed of the roller, so he said: "Let me solve this small problem. I may go on an expedition this fall or next spring. Can I make it in time?"
Heinrich answered firmly: "It would be a bit troublesome to use broadcast-like voice, but the current dot and horizontal signals can be transmitted very far, but I still recommend building a transfer station every 200 kilometers to avoid signal distortion. "
Frederick nodded and said: "I have arranged for people to buy land. I have recently produced more voice communicators for the army. They will be used during the expedition and they may be popular. "
Heinrich agreed naturally when he heard that there was money to be made, and then said: "I have an idea. The communicators sold are equipped with a self-destruction device. If someone wants to dismantle it, Explosion.”
The corners of Frederick’s mouth twitched and he nodded in agreement.
He continued: "I plan to build a number of telegraph stations in major cities in the Rhine League, and then build them in important ports on the North Sea and inland seas. These telegraph stations can transmit information to each other, and then they can Research in this direction.”
"In terms of speeding up the input and output of information, you may want to refer to Professor Ogilvy's calculator. You can discuss it with him when he is free later."
Heinrich immediately took out his notebook and recorded it.
Frederick motioned for him to go out with him, and the two came to Heinrich's office nearby. After cutting off the sound, he said: "I also want a small communicator that can communicate over long distances. The main thing is It is for spies, so specific frequencies need to be reserved for them."
"No problem," Heinrich agreed, "I will pre-divide them for broadcast, telegraph and certain communications. Frequency."
Frederick then said: "I have an idea whether the radio can be used as an invisible beacon to determine the position of ships at sea."
"For example, a ship on the sea can receive broadcasts from two places, and then measure the direction in which the broadcast is sent and how many degrees it is relative to true north. With these two data, it can be displayed on the map He measured his position."
After hearing this, Heinrich started thinking and picked up the white paper next to him to write and draw.
Frederick did not disturb him, just sat there quietly and made him a pot of tea.
"Theoretically it is possible." When Heinrich looked up, the sunset had already filled the sky. "The broadcast signal can be shielded with high magic resistance materials, so just make it like a wooden barrel. The strongest signal is received when the opening of the shielding tube is facing. Although there will be some errors, I think it is enough for use at sea."
Fitter. After hearing this, Lie thought for a while, nodded and said, "This method sounds feasible."
"This is a big business. Coastal cities need to buy broadcasting systems. If the radios are sold, the captains who are not short of money will definitely buy them. It doesn't matter if it is more expensive. After all, it can save lives."
Both of them had bright smiles on their faces, as if they saw countless gold coins waving towards them.
