Chapter 1134 Hand-Cranked Telephone
"Also, don't forget to go to Tianzhu and let them sign the East Land Trade Contract. If this part is filled, the entire East Land trade circle will be complete. Google search reading"
The autumn sun is still very hot. Zhao Xu wiped the sweat from his forehead and threw another sentence to Yang He.
"Yes, Your Majesty, I will go back to prepare and then go to Tianzhu." Yang He heard this and responded with a yes, with excitement on his face.
For him, he has been looking forward to the arrival of this day.
After bowing, Yang He turned and left.
After he left, a little eunuch came to the door with excitement and said something to Xiao Guizi.
Xiao Guizi then smiled and entered the imperial study and said to Zhao Xu, "Your Majesty, Wang Chong, the technical minister of the Science and Technology Department, is here and brought a telephone, saying that he wants to install it for your Majesty."
"Oh?" Zhao Xu heard this with expectation, "Then let him come in quickly, I will be impatient to wait."
Xiao Guizi understood and immediately asked the little eunuch to lead Wang Chong into the palace.
Soon, Wang Chong came with three technicians.
After saluting Zhao Xu, he presented the hand-cranked telephone in his arms to Zhao Xu, "Your Majesty, the Seventh Laboratory of the Research Institute has lived up to expectations and has developed a hand-cranked telephone. Now Yancheng will soon be able to achieve the same conversation throughout the city."
Zhao Xu nodded and said to him, "Stop talking nonsense, get to work, let me experience it."
When the south and west of Dasong were fighting, none of the other functional agencies were idle.
The cabinet was constantly promoting reform, and the Science and Technology Department was one of the results of the reform.
In the future, the scientific and technological development of Dasong will be coordinated by the Science and Technology Department.
The Science and Technology Department headed by Wang Chong has also made many breakthroughs in technology and contributed to the power industry.
This hand-cranked telephone is one of the small achievements.
After all, the biggest problem with hand-cranked telephones is electricity, and the technology of the telephone itself is not difficult.
Simply put, there are two important structures in the structure of a hand-cranked telephone.
One is a rotating dial and a receiver.
This rotary dial structure is actually a small generator.
Each dial is equivalent to generating electricity. This current is like the current of a wired telegraph, which will close the magnetic plate in the switchboard.
Because the current intensity of each shake is different according to the number, the dialed number can be distinguished.
The switchboard then connects the corresponding telephone line with the dialed telephone line, and then the call can be made.
"I heard it all. The emperor said, hurry up and work." Seeing that Zhao Xu was a little impatient, Wang Chong smiled and immediately asked the technicians to install the hand-cranked telephone.
When the hand-cranked telephone was being developed, the laying of telephone lines in Yancheng had already begun.
As long as each agency installed the telephone, Zhao Xu could directly contact the cabinet, the Ministry of Defense and other agencies in the imperial study.
After receiving the order, the three technicians got busy.
In a cup of tea, the hand-cranked telephone was installed.
At this time, Wang Chong said, "Your Majesty, there are only two hand-cranked telephones at present, one in the Research Institute, and one is sent to Your Majesty, so now we can only call the Research Institute."
"Then call your Research Institute." Zhao Xu smiled.
For him, this is already a good start.
The telegraph has certainly brought about a qualitative change in the transmission of information throughout Dasong.
But after the emergence of the telephone, the efficiency of information transmission will be higher.
Next, as long as the hand-cranked telephone is mass-produced, Yancheng can make calls throughout the city, and then between cities, even between provinces, until the entire Dasong.
"The number is two zeros and one two." Wang Chong reported the number of the Research Institute.
"Then my imperial study should be two zeros and one one?" Zhao Xu looked at the ten numbers on the dial.
"Your Majesty is wise, that's right." Wang Chong chuckled twice.
"Too few, change it to eight digits when I go back."
This phone number has only three digits, which means there are a total of one thousand phone numbers available.
If it is changed to eight digits, there will be 100 million numbers to choose from.
Although he knew that Dasong might popularize telephones to the public at present.
But this expectation should be there.
After saying this, Zhao Xu dialed two zeros and one two.
At this time, a woman's voice came from the phone.
"Do you want to transfer to the Research Institute now?" The woman asked, her voice obviously trembling.
Obviously she knew that the other end might be Zhao Xu.
"Yes, transfer to the Research Institute." Zhao Xu replied.
"Okay." After replying, the woman's voice disappeared.
Then there was a "beep" sound from the phone.
Before it rang twice, a voice came from the other side, "This is the seventh laboratory of the Research Institute, long live the emperor."
Zhao Xu heard this, and he didn't know whether to laugh or cry. In this experiment, all the participants concluded that the first call must have been made by him.
Zhao Xu wanted to tease the other party, but he was afraid of scaring them, so he said: "Congratulations on your mastery of the hand-crank telephone technology. This call test was perfect. I am very satisfied. Thank you for your hard work."
"No... not hard." The person on the other end of the phone stuttered, also very nervous.
After asking about the next mass production of hand-crank telephones, Zhao Xu hung up the phone with a satisfied look.
Turning to Wang Chong, he said: "Next, we will speed up the mass production of telephones, and the produced telephones will be directly handed over to the Communication Department."
The predecessor of the Communication Department was the post station system of Dasong.
After handing over the telegram to the post station system, the telephone will now be handed over to the Communications Department for management.
"Yes, Your Highness." Wang Chong replied.
Then he thought of something and said to Zhao Xu, "Your Majesty, in addition to the matter of the mobile phone, I have another matter to report this time, which is the matter of oil. This matter can't be delayed any longer. Before the internal combustion engine is developed, Dasong should establish a petrochemical industry in advance, otherwise the internal combustion engine without oil will be nothing but scrap copper and rotten iron."
"I understand what you mean." Zhao Xu said.
During this period, the Research Institute only relied on a small amount of oil to overcome some smelting technologies in the petrochemical industry.
These small amounts of oil were transported to the vicinity of Tianshan by smugglers from Middle-earth at the risk of their lives, and then transported from Tianshan.
It can be said that the amount is small, but the cost is very high.
The oil that passes through can only be used in the laboratory, but if it is smelted in large quantities, not only the amount is a problem, but the cost will also be sky-high.
Therefore, we must find a way to reduce costs for Dasong next.
To this end, he has instructed Chen Shou of the Ship Department to design and build a merchant ship specifically for transporting oil.
In this way, the transportation problem is solved.
But there is another problem besides transportation, which is the source problem.
This problem requires Da Song to personally take action to reshape the order of the Middle Earth.
Now, Qinshan has flattened Tianzhu.
Then Tianzhu, like Wumu City, has become a springboard for Da Song to extend his sphere of influence into the Middle Earth.
Next, he will use these two springboards to disintegrate the Tusman Empire.
