This time, the telegraph developed by Gewu College is wired, not the wireless telegraph.
The gap between the wired telegraph and the wireless telegraph can be said to be very large, and the wireless telegraph is more complicated, and it is impossible to research it in such a short period of time.
However, if the wired telegraph machine wants to be researched, it is relatively easy.
Because the finite telegraph is very simple to make, and the materials needed are only batteries, electric keys, electromagnets, and armatures, and then connect these things with wires, and a simple signal transmission device is assembled!
Of course, after this is completed, it is still necessary to connect another identical telegraph with a wire. Only in this way can communication between each other be realized.
If the distance is close, use shorter wires to connect them. As for those who are farther away, naturally you need to use some longer wires to connect.
Therefore, the entire telegraph machine is very simple to make, and the parts required are even simpler. The most difficult thing to make in the whole machine is the problem of the battery.
Cao Ang has led the people of Nagwu College to manufacture zinc-manganese batteries, which greatly solved their difficulties.
Although this zinc-manganese battery is a relatively primitive battery, the effect of this zinc-manganese battery is still very good.
"Yes, you have done a good job. After this telegraph is available, the transmission method between us will be greatly changed, and it will be very simple and convenient!"
Cao Ang praised the people of Gewu Academy.
Of course, the reason why Cao Ang praised them was also because of their spirit, the spirit of scientific research.
This is not to say that such a wired telegraph is already very good. Regarding this limited telegraph, it still needs to be improved, because such a wired telegraph cannot compete with that kind of wireless telegraph.
"Of course, the current level of this telegraph machine is still far from feasible. Although this wired telegraph machine has the advantages of stable transmission, it can form a local area network, and it will not be interfered by other media and ears, and will not be monitored by the outside world. , but the defects of this wired telegraph are also very obvious!"
"The reason why this wired telegraph machine has obvious shortcomings is that the defect is on the wire! Once the wire connecting the two parties disappears, it will cause great difficulties for the communication between the two parties."
"So, the research on this infinite telegraph cannot be stopped now, and the research must continue!"
After Cao Ang thought about it, he said to the scholars of Gewu Academy in front of him.
As for the wireless telegraph, the difficulty may be a bit more difficult for those from the Gewu Academy, but the current theory is already in place, and the theory is still very mature.
Coupled with the current technology, it is no longer a problem. As long as the theory is followed, combined with technology, and finally based on one's own creativity, the wireless telegraph can still be developed.
This task was handed over by Cao Ang to Huang Yueying and Sima Yi. In such a situation, both of them lived up to their mission and immersed themselves in this research almost every day.
It is precisely because of the immersion of the two that during this period of time, they have become very familiar with the research of electromagnetic waves, as well as the manufacture and application of electrical appliances.
Such a situation shocked both Huang Yueying and Sima Yi, and fulfilled their mission.
Because of the understanding of this situation, Huang Yueying and Sima Yi are still very confident in developing the infinite telegraph.
After Cao Ang said this, Sima Yi also said afterwards: "Don't worry, we have already caught up with the schedule for the research on the wireless telegraph, and it will not be long before we think about it. It's done!"
When Cao Ang heard this, he also nodded, and then he was full of confidence in Huang Yueying, Sima Yi, who was working hard, and the scholars of Gewu College.
Their research on scientific research and their love for this job warmed Cao Ang's heart. He was so gratified. Cao Ang felt that all the previous investments were worthwhile, and they were quite worth it. He could choose to invest Gewu College is simply the most correct decision made.
Not only Huang Yueying, Sima Yi and others, but the scholars in this Gewu Academy have already possessed very high scientific literacy.
And there are quite a few shining points among them. With them, Cao Ang will not worry that no one will carry the banner of China's technological innovation!
Chapter 466 Step by Step
Now, the technology of this telegraph machine is almost mature. If you want to communicate with each other without any problems, you will naturally need a telegraph code.
It's as if you need to use a pen to write after you have words. Only when the telegraph code is developed can it be used with the telegraph machine.
After Cao Ang thought of such a thing, he also smiled and said to himself: "Now the schedule of the telegraph has caught up, it seems that it is time to start researching telegraph code technology!"
Cao Ang actually has some understanding of this telegraph code technology, so these things are not particularly difficult for him.
And just after Cao Ang said such words, Zhuge Liang who was standing on the side was also very excited when he heard the words, and then he took a step forward and said: "Master Prime Minister, please leave this work to Kong Ming do it!"
This Zhuge Liang was able to stand up, obviously Cao Ang did not expect it, and even more so he did not expect that Zhuge Liang would be interested in that telegram code.
The telegraph code itself cannot transmit sound. The reason why a message can be sent is because it is composed of dots or dashes struck many times.
The dot represents a kind of information, and the dashed line also represents a kind of information, and the combination of the two can form new information.
In this case, the code is composed of the on and off of the current, and then the code is used to form the message to be sent, and finally the specific content of the conversion is composed of the message.
Under such an operation, a piece of information changes from words to codes, then from codes to telegrams, and then from telegrams to words. This is a complete message, and it is the process of information transmission!
Under such circumstances, information can be sent out, and the most famous one among them is the Namos code!
Cao Ang didn't know much about the Namos code, but he wasn't worried about this situation, because Cao Ang had such a group of smart people by his side, and such a telegram code was definitely nothing to them Son!
What Cao Ang needs to do is to tell them the characteristics of the telegram, and then let them develop a code for translating the information according to the characteristics of the telegram. Such a situation is not difficult.
After Cao Ang heard Zhuge Liang's words, he was also very moved, but then he refused: "Kong Ming, I don't need to bother you with this matter!"
"The telegram code is not a difficult task. Whether it is Feng Xiao, Cheng Junshi, Xun Shangshu, they can do it for them!"
"Now I have a new task that I want to entrust to you, I hope you can deal with it wholeheartedly!"
After Zhuge Liang heard Cao Ang's words, he was still a little disappointed, because he was also very interested in the telegram code, and he also wanted to relieve Cao Ang's worries, so he did so.
But, who knew that the prime minister would reject him directly, and Zhuge Liang felt uncomfortable if such a situation was true.
However, immediately after hearing the words of the prime minister, Zhuge Liang's heart became clearer. Regarding such a situation, he must show himself!
Afterwards, Zhuge Liang's whole body became excited, and he heard that he had something more important to explain to him. This situation made Zhuge Liang very happy.
"I don't know what it is, please ask the prime minister to order me to do it!"
Zhuge Liang asked with bright eyes.
Zhuge Liang couldn't wait for such a situation.
Seeing this and hearing the words, Cao Ang felt very happy in his heart. Such subordinates are simply too capable of helping him.
Afterwards, Na Cao Ang also said: "Although the wired telegraph has great shortcomings and limitations, it still has a certain application prospect. Before the wireless telegraph was developed, the wired telegraph was much better. !"
"So the wired telegraph still needs to be managed and built! In addition, after the construction of the wired telegraph, we will be able to carry out the research and creation of the wired telephone along with the wired equipment!"
That's right, the creation of the corded telephone!
For such a situation, Cao Ang has been thinking about it for a long time. Whether it is the wired telegraph or the wired telephone, all they need are wires, and the problem of the wires needs to be solved.
Instead of getting one cable telegraph, it is better to get two together. In this case, it is not too wasteful or not worthwhile for this project.
After Zhuge Liang heard Cao Ang's words, his heart was full of shock. Such a situation shocked his heart so much that he couldn't be shocked anymore.
In such a situation, how can he calm down in his heart?
