Chapter 451 Wireless Communications (2)
This time, after Yang Heng assigned the task, he did not become the shopkeeper, but also went to find something to do.
You know, this wireless communication, it is very simple to say, but in practice, it contains a lot of aspects, if Yang Heng does not interfere, they really can't do anything, and even speaking, Yang Heng is still the absolute main force, and these people are just here to help, that is, after making it, Yang Heng explained to them, and it would be good if they could understand.
What is Yang Heng doing? By the way, he is making electron tubes, that is, vacuum tubes, this technology, temporarily it is really in the process of exploring, originally, Yang Heng also wanted to hand it over to his subordinates, but later, after thinking about it carefully, he handed it over to his subordinates, he just drew the drawings, and they could figure it out, what kind of electrode is this, the getter told them, and they will be able to do it well, especially this electrode, they know how to do it.
Does Yang Heng know how to do it, he doesn't know, you know, in the previous life, the electronic tube industry of the Celestial Empire has always been eliminated in this industry, and it has not caught up with foreign manufacturing capabilities.
Now Yang Heng's plan is that I will first create this thing more than a thousand years in advance, and I don't think foreign countries can surpass our strength.
"Boss, what are you making here, this claw fork?" "If you don't understand, you just watch, and when I make it, you will understand. Yes. Wrong. What I will make, the main force here is you, you know, this glass blowing is your forte, come, such a glass shell, and then weld it with this base. ”
At this time, Yang Heng was in the style of the vacuum tube in his memory. First fix some pins, and then quickly insert them into a small piece of glass water, so there is a tube socket inserted into the glass, and then, Yang Heng carefully installed the electrodes, filaments and other accessories, so a bare tube was made, like this. A glass case was added to the outside, and a semi-finished product came out. Then, the getter is injected through the hole at the top, and then the air is pumped and sealed with a special extraction machine, so that an electron tube is created.
Then, that is the power-on test, if the test is qualified, Yang Heng will make a special aging instrument for aging these tubes, after aging, the unqualified ones will be eliminated, and the qualified ones will be retained, which is as simple as that.
As far as the electron tube is concerned, as long as there are samples and inspection methods, Yang Heng is not worried that they can't make it, and even, they can improve the manufacturing process on this basis.
With the success of the manufacture of electron tubes, it can be said that it is the beginning of modernization, otherwise, whether there is a train, there is a ship, this communication can not keep up, that is also lame walking, only the communication aspect is made up, that is to say, this short board is made up.
Otherwise, what imperial presidential system, republican system, with advanced communication methods, people know more things, it will naturally evolve slowly, it is a group of primitive people, if you teach them to make some modern things, then, their thinking will also slowly change, this is the benefit of developed information, there is no need for Yang Heng to debate with any writers and Confucians in the court.
Although Yang Heng did not run a large-scale newspaper, he had a journal of the academy, especially the later Royal Academy, and even some of the academies of the wealthy families, also followed Yang Heng to study, and they all set up their own journals, and even the sales channels of this journal are quite wide, it cannot be said that it is not a miracle, and it is so inconspicuous that it has nourished into people's hearts, that is, when someone finds something wrong, it has been firmly rooted in people's hearts, and then what to look for, it seems that there is no way to do it, isn't it? It's Li Er's own academy that does this, Li Er is really the one who has no complaints, ban it, can't even the journal of his academy be banned.
There is also a pinyin, which is also slowly promoted in the journal of Yang Heng's academy, from the beginning of a letter to the later pinyin interpretation, in this way, let the pinyin thing, in silence, let people accept it, that is, someone wants to debate with Li Gang, Li Gang does not want to accept it, the same punctuation, that is to give students a powerful learning weapon, and will never worry about interpreting classics in the future.
It can be seen that the power of public opinion lies in the fact that some other academies, at the beginning of the school-running newspaper, also copied the knowledge of some of the Yang family's academy journals to serialize, otherwise, people still don't recognize these journals, in this case, who will debate with whom.
Now, with the electron tube, Yang Heng naturally doesn't just want to make any wireless communication machine, he wants to make it even for broadcasting, and he needs Li Er's consent, no need, as long as it is popular in the academy first.
However, the idea is beautiful, the journey of tackling key problems is hard, just such a vacuum tube, Yang Heng has gone through dozens of technical improvements to really succeed, the first time, he did not set a standard for the pins, that is, this tube needs five pins, I just need to plug in the five pins, and after the tube is made, I am directly dumbfounded, this, what is that foot for, is to find the role of each foot, is it, but also a tube, specially equipped with a tube socket is not possible.
This is the first mistake, the second time, that is, the pressure resistance of the filament is unqualified, and the pressure resistance of a few volts is also eliminated...... In short, after many productions, Yang Heng really asked the glass-blowing technician to weld the glass shell, which is why they saw Yang Heng's success once, and they didn't see the previous mistakes.
With the tube, not to mention the other processes, in short, after half a year, the first pair of radio stations was finally caused, this is a pair of bulky radios, not only can not adjust the frequency, but the volume is also quite huge, that is, the power consumption is also quite huge, so, a radio station in the sky, also need to make a generator to charge it, that is, the battery, can be used for up to half an hour, and then it will be charged, so, this battery is used as an emergency spare part, that is, In case of emergency, the battery can be used to communicate, and usually, the battery is used as a stabilizer component.
So, a new strange thing was born, that is, in the hot air balloon, there is a cross copper wire antenna, when the hot air balloon lifts off, there is an antenna dragged under the hanging frame, and the radio station below is an antenna set up high with a pole, this is the most primitive radio station.
"Snort, hey, hey, hey, dong, I'm Dongliang, please reply when you hear it." "Snort, hey, hey, two holes, two holes, I'm a hole, please say." The first call began in this sneering voice.
Perhaps, in the history of later generations, it will be described like this, in the history of electronics, China's first wireless communication is like this, there are two giant radio stations, in the sky, the earth at the same time to talk, a complete success, representing our country officially entered a great era.
"Okay, everyone, let's raise a glass to celebrate the official success of our first heaven and earth call, and also, the official success of the first long-range wireless call, dry." ",,." There was a sound of wine glasses clattering, and I was happy, a task that seemed impossible to complete was actually completed, so, this time, all the technicians were drunk.
"Everyone, now, this task is completed, but our team can't be disbanded, why, in fact, this is just a start, if a perfect communication equipment is a thousand steps, we just took the first step, the next nine hundred and ninety-nine steps need to be taken by yourself, I will give you a strong backing in the back, can you take the back road well?" "Yes." "Okay, the first task is to make this radio station smaller for me, to the point that people can use it on their backs." (To be continued......)
