Chapter 906: Phone
In the seventh year of Yongxing, Dahua officially entered the era of electrification.
To be precise, it is the Jiangnan area that has stepped into electrification.
Those cities like Guangzhou and Wuhan are still in the age of steam.
As for the countryside, it is still in the farming era.
The Dahua Empire is a country that spans several eras.
If this trend continues, when the Jiangnan area enters the information age, there will still be farming civilization in remote areas.
During this year, many electrical appliances were invented.
Simple ones include electric lights, electric fans, and electric bells. The more complicated ones are refrigerators and rice cookers.
Of course, whether it's simple or complicated, it's all rich people, just to make a new one. There is still a long way to go before popularization, and the cost of these products will come down.
In life, there are few electrical products, and the impact on society is not particularly large.
The bigger impact is on industry.
Rotation can generate electricity, and electricity can naturally provide power to rotate.
Steam engines are too large and heavy to be used in many machines.
Therefore, those researchers are studying how to transform those machines to be driven by electricity, and some results have been achieved so far.
Various forms of electric motors are constantly emerging, improving the efficiency of those machines and making industrial development a few steps faster.
Of course, this is just the beginning, the role of electricity is much greater than that of steam, and there are countless places where electricity will be used in the future.
royal palace.
Several researchers sent a phone to Wu Changqing, and several princes and princesses also came to join in the fun.
Because Wu Changqing told them that this thing talked to people a few kilometers away, and the princes didn't quite believe it.
Wu Changqing picked up the phone and said, "Can you hear me?"
"Chen Jiang Shoude reports back to His Majesty, I can hear you."
A voice came from the microphone, which startled the concubines.
If it wasn't for Wu Changqing being here, they might all be terrified.
A human voice came out of a black iron lump, could it be that he has become a spirit?
The child's world view has not yet formed, so he is not so shocked, but more curious.
They looked at the phone, as if they wanted to explore the mystery.
"Fire a ten-round salute."
Wu Changqing said.
"As ordered."
Soon, ten cannons were fired from the Jiangning camp.
It's really amazing to be able to talk to people who are miles away in an instant.
Chen Yuyan said, this is simply unbelievable.
The other concubines no longer doubted, and believed that there really is such a miraculous thing in this world.
"It's so fun, let's shoot another ten shots."
Wu Yu yelled into the phone, which made Jiang Shoude very embarrassed.
He guessed that it was a certain prince who spoke. It is not good not to obey the order, but it is also not good to obey the order. After all, Wu Changqing is still there.
"Then fire another ten shots."
Wu Changqing said with a smile, this is a historic moment, and he is also in a good mood.
Afterwards, the Jiangnan camp fired another salute, and Wu Yu and the others were excited and noisy, very happy.
This successful call is of great significance.
Since then, Dahua has opened the door to long-distance instant communication.
Telegrams are not counted. Telegrams need to be sent, received, and translated. The process is still very troublesome.
Moreover, telegrams can only transmit text, not sound.
With the telephone, the central government has stronger control over the localities, and there will be no situation where local ministers occasionally do not obey orders.
In the previous feudal dynasties, the central government’s control over remote areas was actually very weak. Those frontier ministers might not listen to the emperor’s orders, and the emperor didn’t even have a good way.
Those ministers can find many excuses. For example, when facing a foreign invasion, the emperor wants the local ministers to declare war on foreign countries. Pseudo-edict'.
In the face of the emperor's imperial edict, we can take the princes of Fenghuo Opera as an example, saying that this may be because the emperor wanted to make his concubine happy.
Then, support the soldiers with self-respect, and watch the show from the sidelines.
This is a typical example of too weak local control, and there are many similar things in history.
When there is no telephone, local officials can indeed use similar excuses to disobey orders.
It's not enough to have a phone, and then I can't say that the voice on the phone is not the emperor's voice.
Moreover, even if the local ministers disobeyed orders, Wu Changqing, who was in the central government, would know about it immediately and respond accordingly.
The role of the telephone is far more than that. Its biggest role is in people's livelihood. It solves the problem of long-distance instant messaging and makes communication between people more convenient.
Of course, phones aren't as magical these days.
The current telephone can only make one-to-one calls, that is, one wire can only be connected to two telephones at both ends. If there are too many telephones connected, it is impossible to accurately call the person you want to talk to.
To solve this problem, it depends on the switch.
The exchange can receive and identify the signal of the dialer, and then automatically transmit it to the designated receiver.
In this way, a single telephone line can carry multiple calls at the same time.
Only by dialing can you accurately reach the person you are looking for.
Only in this way can the telephone enter thousands of households.
Otherwise, there is not so much money to make wires.
The switch Dahua is also in the process of intensive research, and it is expected to have results soon.
With the help of the system, Dahua has no technical bottlenecks.
The speed of its technological development is as fast as chicken blood.
Dahua Daily reported Dahua's first successful call in detail, including the process, content, and participants.
These will all need to be included in the history books in the future to be remembered.
However, it is a bit far-fetched to say that this is the first time that Dahua has made a successful call. Previously, when the researchers were researching and debugging, they had succeeded countless times, otherwise they would not have taken it to the palace to present the treasure.
However, the moment when their experiment was successful is not commemorative.
This commemorative moment should still be reserved for the emperor.
Ever since, the call between Wu Changqing and Jiangning Daying was defined as Dahua's first successful call.
Many ordinary people are confused about this call, and even a little bit in disbelief.
How can it be possible for a person to talk to someone seven or eight kilometers away? Whoever has such a loud voice can become a monster.
Those who read the books and understood the science believed it.
However, believe me, when the phone really appeared, these people were quite surprised in their hearts.
This technology is really amazing.
Before doing it, they didn't even dare to think that there could be such a magical weapon in the world.
Some people who think farther away have been able to realize the impact of the telephone on the world. That kind of effect is exciting just thinking about it.
