Chapter 171: Father's New Move

After a while, Professor Su Guangsheng came back to his senses and asked, "Artillery commander?" How do you know this thing? ”

Guo Zhuocheng held back the curiosity in his heart and simply told him what he had done in the army a few days ago. He said, "I'm anxious about them like that." Such a large amount of calculation, each number jù is purely calculated by hand, not to mention hard work, but also full of random factors. So most of the jù values need to be selected based on the experience of the expert, and if someone is inexperienced, or if the expert makes a mistake, the situation will be very bad.

The worst thing is to delay time, in order to calculate the shooting yuan, the troops have to sweat for ten minutes. If we can use the 0 chip to develop a special computing instrument for artillery, wouldn't it be possible to reduce those random factors, wouldn't it be possible to greatly reduce their workload, wouldn't it be possible to improve the reaction speed of artillery? I think even if it's just one minute shorter, that's a big step forward. ”

After Guo Zhuocheng finished speaking, Su Guangsheng smiled bitterly: "Xiao Guo." To tell you the truth, in fact, we have previously developed an artillery command instrument for artillery. It took us a lot of manpower and material resources, but what was the result? This artillery command instrument was almost never used passively after it was delivered to the troops, and it was rusted when thrown in the warehouse. When I think about it, I am ashamed. ......, you come ......"

As he spoke, he walked over to a data cabinet and opened the door to bring out a large pile of drawings from inside.

With Guo Zhuocheng's rich experience and product development experience in his previous life, he only needed a few glances at the overall assembly drawings to know why the troops were reluctant to use it: this set of command instruments was too cumbersome to use

Just like the computers of this era, there is no display screen output number jù, no keyboard input number jù, let alone the connection between the gun position and the command post and the computing room. When the artillery observer reports the number jù from the front, the operator of this instrument must input these numbers jù into the punching machine, the punching machine punches holes in the paper tape, and the operator checks that the hole position on the paper tape is correct, and then enters the paper tape into the tape reader, and then the instrument begins to work, and the calculation result is output with the punched paper tape.

With his own expertise, the operator reads the meaning of the dense holes in the paper tape, reads them out, and then reports to the head of the command post, who gives orders to the gun position. If there is a mistake when punching a hole and the operator does not see the problem in the countless holes, the result is catastrophic.

Coupled with the fact that the quality of the chips and systems at that time was not stable, it was easy for artillery commanders to have the urge to hit the wall.

Guo Shucheng's eyes moved away from the drawings and said: "This kind of command instrument can only be said to be useful in principle, and in practice, it is equivalent to one more ancestor who needs to be taken care of, and it is better to use it than to calculate it manually." ”

This was said to death with shame, but Su Guangsheng did not get angry, but asked, "Do you have a better idea?" Can you overcome these shortcomings? ”

Guo Shucheng nodded and said, "I have." I started by designing an input system that had to be fed directly into the microprocessor, eliminating the need for error-prone punching machines. Secondly, we must design a simple display system, that is, at the same time as the number jù input, the number jù must be displayed, so that the input person can judge in real time whether the number jù he entered is the same as the number jù that should be entered. The third problem to be solved is that this display system can also display the calculation results, instead of spitting out a series of paper tape No, I also plan to add a joint function. ”

Su Guangsheng thought that what Guo Zhuocheng said earlier was too large and complicated, but he was very puzzled by what he said later, so he blurted out: "What is the joint function?" ”

Guo Zhuocheng said: "It is to transmit the final result to the people who need these numbers through the guò transmission network. After the operation number jù comes out, not only the operator can see it, but also the head of the command post, and the officers and men of the gun position can also see it. It seems that the order is issued, and the officers and men of the gun position can adjust the firing according to the displayed number by pressing a button or saying a word first. ”

Su Guangsheng was stunned and asked eagerly: "Yes, it is not difficult to realize this joint function, the telephone line will do." Your idea is good. Then, he said skeptically, "But what does this display system do?" ”

Guo Zhuocheng can't say that he uses monitors and televisions at this stage, after all, he is a little ahead of his time, and this workload is still relatively large, so he can only wait for later.

"We're going to use a digital tube for the time being, and we're just going to show some Arabic numerals anyway," he said. As for the input system, we can set several fixed parameter performance keys. For example, if we press the button marked 'X coordinates', the next number jù is the number about the X coordinates, and the commander will store it in the memory corresponding to the X coordinates‖ if we press the button marked 'Wind Power', the next number jù indicates the wind level and direction, and the first two digits indicate the wind force and the last two digits indicate the direction. ”

At present, there is no concept of keyboard and mouse in China, so Guo Zhuocheng can only adopt such a clumsy method for the time being, and wait for the success of this command instrument to further improve.

Although Guo Zhuocheng said it very simply, and the method was not clever, because he had adopted some advanced methods in later generations, Professor Su Guangsheng sounded that it was simply extremely advanced, and he was smart enough to think about it a little and felt that it was not very difficult to realize.

Everyone knows that sometimes technology is not a profound thing, as long as someone breaks it, some advanced technology will become very simple. Many times what is needed is not advanced development, but a good idea.

Su Guangsheng said that he would do it, and he forced Guo Zhuocheng to draw the schematic diagram and functional block diagram with him.

He is a computer expert with a solid foundation, and he is also an expert in microelectronics, and often Guo Zhuocheng only says a beginning, and he immediately understands the meaning and finds a solution.

Sometimes Guo Zhuocheng even thought that Su Guangsheng had known such a thing for a long time, and deliberately asked him Guo Zhuocheng to come over to show his hand.

It's just that when it comes to 0 circuit design, especially peripheral circuit design, Su Guangsheng is not so shrewd, so he seriously looks at Guo Zhuocheng's design, looking like a primary school student asking for advice: "Is this okay?" ......, that's it, it's ......."

What made Guo Zhuocheng laugh was that Professor Su Guangsheng dragged him to stay in the office for a whole day, and even let his subordinates cook in the middle of the meal, and did not let Guo Zhuocheng go back to the dormitory until late at night, and when he left, he repeatedly told him to arrive early tomorrow and take out the principle as much as possible.

Back in the dormitory, the three people in the same dormitory had washed up and were ready to go to bed. When he came in, Liu Yuanchao smiled and said, "Guo Zhuocheng, how old are you?" I'm not in love, and I'm still stepping on several boats. ”

Even Kuang Guosheng, who was not smiling, smiled and said: "Our Xiao Guo must be liked by girls, but we can't step on several boats." ”

Guo Zhuocheng knew what they were laughing at, and he must have received the letter again, and there must have been a lot of girls' letters in it.

Not to mention their dormitory, but their class and their school, Guo Zhuocheng received the most letters. Especially in the first few days of school, a large number of letters came every day, and there were more than 50 letters a day, and the letters of more than 70 people in their majors added up to less than that of him alone, when the students in charge of sending and receiving letters were stunned.

For this reason, Guo had to dedicate a drawer to his desk to storing these letters.

Most of the people who wrote the letter were students of Guo Zhuocheng when he was a teacher in a cram school, especially those who were admitted to universities. They wrote to express their gratitude and happily reported on their university life, allowing Guo to share their joy.

There are also some people who write letters to ask for some mathematics, physics and chemistry topics, and there are constantly those who failed in the college entrance examination last year, and there are also those who are ready to take the college entrance examination this year.

In addition to these people, there were also Principal Shu and others, his parents, grandparents, and grandparents and Yuan Li in the capital.

Of course, the most and most diligent writers are Liang Liang and Shu Qiao, these two women write two letters a week, and they can't move. At the beginning, both of them had a trace of resentment in the letter, complaining that Guo Shucheng threw them in the capital, but they ran to Yunnan University in Yunnan Province alone. Later, they slowly wrote about their lives, their studies, and the friends around them.

Such a high frequency of writing letters, and obviously the handwriting of girls, naturally made the classmates think that Guo Zhuocheng was in love, although he was really not the age to fall in love, but they just liked to think in this direction.

Later, that Yuan Li also joined in and also started to write two letters a week. And this girl obviously didn't believe what Guo Zhuocheng's grandparents said that Guo Zhuocheng was only ten years old, and in her mind, Guo Zhuocheng was only one or two years younger than her, especially the scene where he asked the printing house to give them college entrance examination materials, and the scene where he beat Li Guowei's gang of hooligans by himself, which was deeply imprinted in her mind, and she felt that he was more mature than herself, and she could treat him as a peer.

So there is really a little bit of girlish affection in her letter.

It's just that Guo Zhuocheng doesn't have ambiguous thoughts with them now, and replying to a letter once a week is very formulaic, and sometimes he simply doesn't reply because of a delay in playing ball or other things.

But the letters of the three girls still flew in on time and were not interrupted for a week, which made Guo Zhuocheng a little speechless.

Sure enough, there was a pile of letters piled up in the drawer of his desk dedicated to the new letters, at least ten today. He first smiled at Liao Xinwen, the volunteer postman: "Thank you." ”

Liao Xinwen smiled a little embarrassedly: "It's okay." ”

Then, Guo Zhuocheng flipped through all these letters and saw the letters from Liang Liang, Shu Qiao, and Yuan Li: "It's really a bit of a coincidence this time, the three of them came together." ”

At the end of the stack of letters was a thick cowhide envelope, which he immediately recognized as his father's notes. His heart moved: "Could it be that the article written by my father has been published?" ”
