Chapter 930 Is there a problem with firepower? !
The purpose was to guide them onto the path of research, so Gao Zhendong chose a topic that was neither too difficult nor too easy.
Their discussion was exactly what Gao Zhendong liked to hear. After a long discussion, under Gao Zhendong's guidance, they finally determined the first technical parameter: 256 colors, one byte to store one pixel's color information, and storage bits allocated according to the number of R3G3B2. Only then did they realize that even these 256 colors consumed a horrible amount of memory.
256 colors are basically enough for industrial use, after all, only four colors are needed to draw a map. Of course, the four-color theorem has not been proven yet and can only be regarded as a conjecture.
Taking the memory consumption into consideration, the resolution of this color display is naturally not high, 320*240.
At this point, Gao Zhendong was not going to continue on this issue. He would just focus on these two core parameters and let them play with the rest.
The comrades also knew that it was impossible to solve all the problems here at once, so they turned their attention to the second topic.
"Scanner? Mr. Gao, what is it used for?"
"You put the paper in, and then the device can read the content on the paper and turn it into a picture, which is then stored in the computer."
"Ah~~~~~~" The comrades exclaimed, this thing is difficult to deal with.
With the experience of color display just now, the comrades understood that even though fax machines are now available, the principle of that fax machine may still be used, but it is almost the same as the "scanner" that General Gao mentioned.
Because fax machines don’t need to store data! They can even directly transmit analog signals, and the other party can just restore the analog signals. This is completely different from a “scanner” that needs to be digitized and stored. Even the technology they use to read images may not be the same.
For example, how many colors should this "scanner" support? This question once again came to the minds of comrades.
Unexpectedly, Gao Zhendong waved his hand and said: For this thing, black and white is enough, and it would be better if it supports more grayscale.
Oh, that's easy.
"Chief Engineer Gao, I think the core problem of this scanner is not the color." Deputy Director Gao felt that there was something fishy after listening to Gao Zhendong's words.
Gao Zhendong nodded: "Well, indeed, the core problem of the scanner is not color."
"Resolution, yes, resolution, but I don't know how to describe this resolution. It's different from the monitor, and it feels awkward no matter how I describe it." Deputy Chief Gao touched his head, not knowing what to say for a moment.
The resolution of a scanner is different from the resolution of a monitor.
Gao Zhendong came to his rescue: "Well, your idea is very accurate. In fact, let's change the term "resolution" to mean the degree to which the scanner can analyze the scanned object."
"Oh, right, right! Chief Engineer Gao has the clearest idea. That's what I mean. The scanner can resolve so many points per unit length." Deputy Director Gao's ability is still online.
"Well, we use points/cm to define this thing. I hope to achieve 50 points/cm. If it is really impossible or has no practical value, then it is okay to reduce it a little bit."
In his previous life, Gao Zhendong was annoyed by the DPI (Dots Per Inch) unit. It was difficult to change and difficult to calculate. Now I have figured it out first and I have the final say!
If you really want to use it, then use DPC (Dots Per cm).
50 dots/cm, or about 150 DPI, was barely usable in Gao Zhendong’s previous life, but in this era, it is a very huge number.
This number shocked the comrades. When they calculated it on a piece of paper, the storage capacity was simply terrifying.
"Boss Gao, if we sweep it out like this, there's no way we can save it!"
Gao Zhendong also knew this problem and said with a smile: "This is the original resolution. In fact, the final stored image must be compressed by an algorithm. The final stored image resolution will not be as large as resolution*size. We will discuss the specific algorithm and processing method later."
After saying that, he pointed to the printed paper in his hand and said: "The scanning format should be based on the 16K printing paper we use." 16K printing paper is at the same level as A4 paper, and it is a commonly used paper size nowadays. This range is sufficient.
After a piece of 16K paper is scanned and compressed, if the content is not particularly complex, it can be compressed to an acceptable level. A 15 cm floppy disk can store about one to three pictures. Considering the double-sided disks and drives that comrades are currently working on, that is six pictures.
Considering the existence of larger capacity tapes, it is basically enough to carry and transfer some small files. The reason why Gao Zhendong attaches importance to this is that in addition to digitizing some important files and allowing them to be transmitted directly, there is also the issue of encryption of these files during the transmission process.
This transmission includes network transmission and manual transportation of storage media.
Paper documents are difficult to encrypt and decrypt, but digital documents are different. For important documents, they can be scanned and encrypted. Even if they are intercepted or lost, it is difficult for others to obtain the actual content. "I see, that means black and white, 256 levels of gray, 50 pixels/cm, right?" Deputy Gao said.
Gao Zhendong nodded: "Yes, this is the core parameter. Another parameter is the scanning speed. I will not set a rule for this. You should try to make it as fast as you can. Think about the specific technical means to be used, form a plan, and then we will discuss it."
This scanner is destined to be expensive. Unlike the scanners in my previous life which were everywhere and very cheap, the scanners at this time have very high hardware requirements. It can be said that they must be installed in a good enough computer to handle it properly.
However, this thing is not common in the streets these days, but is used by important departments.
"Okay, we understand." Deputy Director Gao understood what Director Gao meant. He would not provide the technology too early or too quickly for these things. Instead, he wanted the comrades to work hard and grow on their own. It could be said that he was taking great pains.
In fact, this is just one reason. Another reason is that Gao Zhendong does not want to spend money to get it from the system now. He hopes to get this thing done relying solely on his own memory and the efforts of his comrades.
Moreover, the technology of the past may not be suitable for the present, and it may often be too advanced. Not to mention, the scanner is a crappy thing that has never been produced in those stores and is a niche device.
The comrades were very excited to get the new topic, and Director Gao didn't need to worry about the rest. Deputy Director Gao quickly divided the comrades into two groups based on their expertise and specialties, and they all started working on it.
This is the first shot of the Computer Peripherals Research Institute of Factory 1201, so we must do it well.
When the leader of the 12th Ministry of Machine Building received the report from the Peripheral Equipment Research Institute, he took a closer look and laughed.
"It seems that Gao Zhendong has high expectations for this. He doesn't even want to be a babysitter, and is forcing his comrades to do it themselves."
He was bound to be involved in anything related to Gao Zhendong, so it would not be too much for that kid to take it seriously.
"I also think that maybe one of these two things has a good foundation, and the other has a narrower use. In the context of neither being urgent, he let the comrades practice more on their own. It's a bit like peripherals such as JP-59 and XS-59." The chief engineer of the th Ministry of Machine Building also laughed.
"Well, his consideration is reasonable. We still need to cultivate talents. A single flower does not make spring, but a hundred flowers in full bloom make the whole garden full of spring."
The leader signed his name on the project application report with a flourish of his pen.

"Boss X, when will you hold this meeting? After this battle, we have a lot to say. We have gathered all the people and have been waiting for this day."
The comrades in the army are a little impatient. The battle has been over for so many days, but the summary meeting has not yet been held. What if the comrades have forgotten the experience?
The chief engineer of the Defense Work Committee smiled and said, "Don't worry, you guys are quick in mobilizing people, but we can't mobilize relevant personnel that fast. The comrades in the relevant units and factories all have important tasks to do. No matter how urgent it is, we have to wait until they are free. Even if we start in batches and systems, we can't start all at once. So, we'll start one tomorrow."
"Which one?"
"Let's start the army's first, they have a lot of things to do, haha." The army is the main force, with the most combat operations, so naturally there are more things to do.
The next morning, Gao Zhendong sat in the conference room, listening to his comrades talk about the battle process and experience, feeling particularly satisfied.
I definitely can't go to the battlefield, so it's good to listen. As for this enemy, I can only let my comrades kill it for me.
"...Let me talk about the biggest problem that our comrades have reported during the battle..." said an army comrade.
Since it is a summary, we must talk about both the good and the bad, keep the good and improve the bad, but the most important thing has to be the bad things.
It's an old habit that has been passed down for thousands of years. If we get an advantage, we just brush it off, but if we suffer a small loss, we will write three pages in anger.
This is also what the comrades attending the meeting attach the most importance to.
"The biggest feeling during this operation was the problem of firepower."
Many comrades are a little bit upset. How much more firepower do you want? This time, it can be said that the biggest change is the firepower. Your infantry is only short of a small cannon. What else do you want?
However, no one doubts that everyone has this disease. It may have improved recently, but it cannot be cured, and it will never be cured in a lifetime.
No matter how strong the firepower is, you can always find a place where the firepower is insufficient.
"Machine guns! The biggest problem is the machine guns. The heavy machine guns are too heavy! They can't keep up with the troops. If it weren't for the 61st squadron's machine guns, the assault rifles could fire continuously, and there were also gun-mounted grenades, 61 fire, and Red Sword-61 as supplementary assault weapons, we would often be at a disadvantage in a shootout with the heavy machine guns in the bunker."
No matter what people say, do you want to hear what the hell you have to say?
