Bright Sword Military System

Light-emitting diodes are modern LED lights, which were developed in 1962 and are widely used in digital displays in modern times.

For example, traffic lights for traffic display, numbers on electronic watches, numbers on elevators, etc.

This thing is actually not complicated, that is, a diode made of a semiconductor compound such as gallium can emit light of a specific color: gallium arsenide emits red light, gallium nitride emits green light, indium gallium nitride emits blue light, and so on.

Compared with ordinary incandescent lamps, it has many advantages: long life, less power consumption, less heat dissipation, fast response, and frequent switching on, etc. (traditional incandescent lamps are easy to burn out if frequently switched on).

In particular, the light emitted by this thing is not as dazzling as an incandescent lamp, so it is very suitable for data output.

This is not a high-tech thing, and the reason it was developed so late is simply because no one had discovered that gallium compounds had this property before.

Wang Xuexin knew this, so of course he would not let it go easily.

He immediately assigned the tasks: Su Liguo was in charge of making the diode with gallium nitride, and Chen Jiefeng was in charge of converting the data output into recognizable numbers.

There is no problem with Su Liguo. For him, it is all about making second-line tubes. Now it is just a different material. He just doesn't believe that using this material to make a second-line tube can emit light... Is there such a magical thing?

But believe it or not, there is no difficulty in the program and technology, so I nodded and agreed.

But Chen Jiefeng was dumbfounded.

"Leader!" Chen Jiefeng said: "You mean, we can see the numbers '1', '2', and '3'? Even if this kind of second-line tube can emit light...how can we change the data into this?"

It's not Chen Jiefeng's fault. There are many things that are commonplace in modern times, but it is a great idea at this time.chimney

Wang Xuexin said while drawing on the manuscript paper: "We can arrange seven light-emitting diodes to form a character '8', and then the surrounding six lights are the number '0', and the two poles on the right are the number '1'..."

Needless to say, Chen Jiefeng immediately understood what Wang Xuexin meant. At the same time, he was surprised to find that every number from 0 to 9 could be displayed easily with this method.

As for the hundred and ten digits, you only need to put them in the corresponding positions.

Chen Jiefeng looked at the manuscript paper and then at Wang Xuexin. He couldn't believe that Wang Xuexin came up with such an idea at his fingertips.

"Can it be realized?" Wang Xuexin looked at Chen Jiefeng who was on the spot in a daze and asked.

"Uh, yes... of course!" Chen Jiefeng replied.

The difficulty is that the idea of ​​this display can be implemented even by a novice in programming... When programming, you only need to control which diodes are powered to display correctly.

"Very good!" Wang Xuexin said: "After designing the program, hand it over to Mr. Su, and let him integrate the program on the chip!"

"Yes!"

After finishing all this, Wang Xuexin breathed a sigh of relief and solved another difficult problem. It seems that he can relax now.

Go see what Su Xin is doing!

In case she sees her resentful expression again next time.

However, just after Wang Xuexin took a few steps, the correspondent came to him: "Head, Staff Officer Huang called and said that there is something wrong with the aircraft carrier transformation!"

As soon as Wang Xuexin heard that there was a problem with the transformation of the aircraft carrier, he immediately rushed back to the headquarters in a hurry.

"What's the situation?" Wang Xuexin grabbed the phone and asked, "What's wrong?"

He felt a little strange, Ying Jiang was responsible for the transformation of the aircraft carrier, and he also used the export of 2000 transistors as a guarantee, so there should be no problems... Even if there is a problem, you, Ying Jiang, need to solve it, otherwise, do you still need 2000 transistors per day?

Staff Officer Huang reported: "Commander, it's like this, Ying Jiang is going to use dynamite to blow it up!"

"What? Explode with dynamite?" Wang Xuexin frowned, what is Yingjiang doing!

"Yes!" Staff Officer Huang replied: "But I stopped him, but Dr. Aubrey hopes to talk to you!"

"Let her answer the phone!"

Soon Dr. Aubrey's voice came on the phone: "Comrade Commander, I'm Aubrey!"

"Are you planning to demolish it violently?" Wang Xuexin asked.

"Well, almost!" Dr. Aubrey replied: "If you plan to complete the transformation within three months, this is the only way to do it!"

"Can you guarantee that it will not damage the structure of the hull?" Wang Xuexin asked back.

"What a joke!" Aubrey laughed. "Its deck is more than 400 millimeters thick, and what we 'violently demolished' is only the half of the ship island, which is difficult to cut because of the small space!"

Then Aubrey added: "In addition, you have reduced the flight deck to 60MM. If such a 'violent demolition' can't bear it, I don't think this 'aircraft carrier' needs to be driven out at all!"

"If you don't do this, how long will it take to finish?" Wang Xuexin asked.

"It will be delayed for at least one month!" Aubrey explained: "The central ship island is the most difficult part of the project. After dismantling, the flight deck will be installed, and the chimney will be dismantled after that!"

According to common sense, the central island and chimney must be dismantled to install the flight deck, because these two things are the tallest on the battleship... Other places are fine, as long as the height of the flight deck is raised, it can be covered in the lower hangar.

For example, the naval gun only had its main gun removed, and the turret was not removed, and it was directly used as a support point and ammunition depot for the flight deck.

Aubrey also took a shortcut on the chimney: she didn't demolish the chimney first, but opened a hole in the middle and lower part to build a new chimney inclined at 23 degrees to the edge, and the smoke exhaust was blocked at this position.

The remaining chimneys will be removed to expose the part of the flight deck first, and then the remaining parts will be dismantled according to overall planning.

Wang Xuexin doesn't need to think about these things. At this time, he only thinks: more than a month... Although this is not a long time, what if something happens during this period and needs to be urgent?

The situation in wartime is uncertain. Sometimes if you miss a minute or two, you may miss an opportunity, let alone more than a month!

Thinking of this, Wang Xuexin gritted his teeth and said, "Demolish it according to your ideas!"

"Wise choice, Comrade Commander!" Aubrey said, "But first of all, if something goes wrong during the demolition process, we will not be responsible!"

"You just said it's fine!"

"That's just an estimate!" Aubrey explained: "But there are contingencies in everything, for example... the quality of this warship is not up to standard, or some accident happens. This is beyond my control! We are only responsible for refitting!"

"Okay!" Wang Xuexin nodded helplessly: "You don't need to be responsible!"

Even if Aubrey was asked to be responsible for this matter, she couldn't afford it.

But as long as Wang Xuexin calls Sun Erwei, as long as Sun Erwei understands that this is linked to 2000 transistors per day... Aubrey will be careful.
