Chapter 851 The First Trial of Listening to the Lecture
The magnet phone made in the village has a battery inside. The electric sound of the battery is carried, and the hand crank emits alternating current. People use this to connect to the artificial switchboard. .
The person in the manual switchboard is equivalent to a microphone builder. One person shakes the phone. When he sees that the sign has fallen, he picks up the phone and asks the other party what he wants. What the other party says he wants, he puts the plug of the other phone with This one connected, the phone rang over there, and they picked up the call.
Since there is no filter, carrier equipment cannot be manufactured, so one telephone line can only connect one phone.
For example, the manual clearinghouse is x, and the telephone numbers at other different locations are abcdefg. Each of the seven locations must be connected to x by a telephone line.
If a and b are on the phone, and c wants to find a or b, it will not work, unless c has greater authority, then c finds x, x helps the connected ab, and turns around to communicate with ab. If it is broken, connect c to a or b.
Whoever has the greatest authority depends on whose status is high and whose matter is serious. Zhu Yuanzhang guarantees that he will have the first priority. However, if there is a mutiny in the military camp and there is a call, priority will be given to the military camp line.
But the magnet phone has a shortcoming. The distance is too long. When transmitting from one Xiaqiu village to another Xiaqiu village, the electricity is not enough.
Then the local power supply can be installed at the manual exchange, and this power supply can provide channels for multiple telephone line signals.
In other words, the phone line is always powered and you can make calls at any time.
Zhu Wentian tested the magnet first, waiting for everyone to get used to it, then set up the phone line over there, and then replaced it with a shared power one.
The village still has electricity, but when the phone lines are set up they look like spider webs.
"This is the phone call for now, and we will get the telegraph machine later. We are going on a long trip and need to contact here at any time. Wireless telegraphy is not very technical and does not require diodes."
Zhu Wentian said to I am very satisfied with the phone. The next step is to take out the telegram before leaving. The one cannot be called, and the other requires higher technology to build a radio station.
Normal telegrams use Morse code. According to the rules, they are replaced by numbers. Four numbers represent a Chinese character. You can look it up while holding a book. No encryption is required.
When you have a telegram, why not light a beacon? If you see the enemy, send a telegram, then get on the hot air balloon and run away, and continue sending messages on the hot air balloon.
“Let the village’s man-made parts, some simple ones, such as casings and so on, be sent to the industrial zone.
We don’t use dry batteries in the village, just use lead-acid batteries. There are many, and they can be recharged. Dry batteries are expensive.
Chemical batteries can only be dismantled after being used. It is troublesome to choose the ones that can still be used and continue to make batteries. ”
The little girl thinks it’s troublesome. Instead of plugging dry batteries into the phone, it is better to connect a storage battery. The voltage can be adjusted.
“First build a few for everyone to play with, and then share the power. You need to connect two more transmission lines to avoid problems with one generator.”Zhu Wentian thought about it, the battery is not as good as the shared power.
When I come back from this trip, I will rebuild diodes and other electronic parts. With the carrier, I can add several more phones to one wire.
Of course, when laying wires to another Xiaqiu village, several iron wires were also installed together.
Tell the people not to knock down telephone poles and steal phone lines. It is useful and the court is of great use.
And if you see someone causing damage, report it and get rewards.
At noon, the hot spring bathers went to rinse with ordinary water again. The hot springs contain high mineral content. Except for the bubble hot springs, other hot springs are not suitable for drinking.
Zhu Yuanzhang felt refreshed, changed into casual clothes, and sat upstairs again, where people were already buying spicy rice noodles.
The ministers arrived first and greeted him, the queen, the prince and others.
He saw something extra on the table, and he looked at it and said, "It should be long, for eating."
"Your Majesty, it is for delivering messages, calling the phone, and using the phone to talk." , can talk directly, the other one is downstairs, you can send someone down to listen."
The head of the village doesn't want to introduce more, just give it a try.
"I'm going." Queen Ma was afraid that others would lie, so she wanted to verify it herself.
Empress Ma went downstairs, and Zhu Yuanzhang rang the phone under the guidance of the head of the house. A voice came from inside, "This is a manual exchange. Who are you looking for on the 1st?"
"It's Ling'er." Ah, let's find Queen Ma, she's downstairs." Zhu Yuanzhang heard the noise and thought it was interesting, but he didn't see the little girl.
"Wait a moment, I'll transfer it for you." The little girl over there said, inserting No. 02's plug, connecting both parties, and sending a signal to No. 02 at the same time.
When the phone in front of Queen Ma rang, she picked it up at the signal of others, "This one can talk."
"Sister, it's us, are you serious?" Zhu Yuanzhang heard it again .
"It's me, Chongba, are you upstairs?"
"Yes, I'm upstairs, and you're downstairs"
"I We just came down, what are we going to eat today?”
“Let’s have some mutton soup or the garlic pie this morning.”
“I’ll go up right now and let’s go together.”
"Okay"
Not long after, Queen Ma came up and the two of them repeated it in person.
"Oh, Biao'er, please go down, wait a minute, let's write something, and you can read it for us when you go down."
Zhu Yuanzhang was surprised and didn't want to torment the girl all the time. The son goes downstairs.
There are four treasures of the study upstairs, as well as pencils. Zhu Yuanzhang simply wrote a sentence with the pencil, folded it after writing, and handed it to Zhu Biao.
Zhu Biao ran down. The phone was not disconnected. He picked it up and said, "Father, Father, are you listening?"
"Listen and read"
< p>"If you don't replenish yang during the Qingming Festival, the doctor will have a broken heart. Father""Come up, good stuff, who made it? Call us. What do we want to eat later? Call the village, village Prepare it and send it away."
Zhu Yuanzhang looked at it.With bright eyes, I thought of a use.
The ministers ""
When they were equally shocked, they found it difficult to agree with the use of such magical means to order food.
Zhu Biao ran up and returned the note to his father, "Father, you can really hear me."
"Yichang, this is not upstairs or downstairs." Zhu Yuanzhang considered the distance issue, Upstairs or downstairs, just shout.
"Your Majesty, it can be far or near. The current one is more than thirty miles away. There will be one further away in the future, and it will be available soon."
The lieutenant nodded, no. There are lights and telephones upstairs and downstairs. You can even call downstairs if you have to.
"How do you talk when you are so far away?" When Zhu Yuanzhang met him for the first time, he had too many puzzlements in his heart.
“It’s the same as electric wires. Wherever the electric wires are laid, this one can be connected to it. It requires wires.
The village plans to set up electric wires to the village over there, and then connect them to Ningguo Mansion and Taiping Mansion are convenient for talking to the government.
With this, you can know the situation of Maanshan Iron Mine, industrial area, factory area, military camp, etc.
This is the truth."
The village leader repeated the knowledge he had learned to everyone. He himself thought it was good and it was convenient to use.
Zhu Yuanzhang nodded repeatedly, waited for the chief to finish speaking, and said, "Let's call someone to see us. Just use this. After dinner, go and set up wires for us. All nearby state capitals will be wired across the Yangtze River." "Please remember to collect it.
