Chapter 930 Is there any firepower problem? !
It was originally intended to guide them on the road of research, so Gao Zhendong chose such a topic that is difficult to say whether it is high or not, or too low.
Their discussion was something that Gao Zhendong liked. After discussing for a long time, he finally determined the first technical parameter under Gao Zhendong's guidance. The number of colors is 256 colors. A pixel uses one byte to store its color information, and allocate the storage bits according to the number of R3G3B2. Only then did they realize that even this 256 color is a very terrifying thing to consume the memory.
256 colors are basically enough for industrial purposes, after all, you can draw maps in just four colors. Of course, the four-color theorem has not been proved yet, so it can only be regarded as a conjecture.
Considering the memory consumption, the resolution of this color display is naturally not high, 320*240.
At this point, Gao Zhendong is not going to continue on this issue. Just these two core parameters, let them play freely.
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 this for?" "It's just put the paper in, and then this device can read the contents on the paper into a picture and store it in the computer." "Ah~~~~~~" The comrades were amazed. This thing was difficult to deal with.
With the experience of color display just now, the comrades understand that although there is a fax machine now, the principle of that fax machine may be useful, but it is almost two different things to the "scanner" mentioned by Mr. Gao.
Because the fax machine can be stored without storage! It can even directly transmit analog signals. Anyway, it can restore the opposite side based on the analog signal. This is completely out of touch with the "scanner" that needs to be stored after digitization, and even their technology of reading images is not necessarily the same.
For example, how many colors should this "scanner" support? This question once again came to the minds of comrades.
I didn't expect Gao Zhendong waved his hand: This thing is just black and white, just support a few more gray levels.
Hey, this is simple.
"General Engineer Gao, I think the core issue of this scanner does not seem to be color." Deputy Director Gao listened to Gao Zhendong's words and felt that there was a pit inside.
Gao Zhendong nodded: "Well, indeed, the core problem of the scanner is not color."
"Resolution, yes, resolution, but I don't know how to say this resolution. It's different from the monitor, and I feel awkward no matter how to say it." Deputy Gao touched his head, not knowing what to say for a while.
The resolution mentioned by the scanner is different from the resolution of the monitor.
Gao Zhendong helped him out: "Well, your idea is very accurate. In fact, let's change the resolution you mentioned, resolution, that is, the extent to which the scanner can resolve the scanning target."
"Hey, yes! Chief Engineer Gao can figure it out, that's what it means. In terms of each unit length, how many points can the scanner analyze." Deputy Director Gao's ability is still online.
"Well, we define this thing with dots/cm. I hope it can be 50 points/cm. If it really cannot be done or does not have practical value, it is okay to reduce it appropriately."
Gao Zhendong looked at the DPI (DotsPerInch, dots/inch) unit in his previous life, and it is not easy to change, and it is not easy to calculate. Now I will make it first, I have the final say!
If you really want to use it, then DPC (DotsPercm).
50 points/cm, about 150 DPI, was barely available in Gao Zhendong's previous life, but in this era, it was a very huge number.
This number surprised the comrades. After counting a piece of paper, the storage volume was simply scary.
"Mr. Gao, you can't save it at all!"
Gao Zhendong also knew this problem and smiled and said, "This is the original resolution. In fact, the final stored pictures need to be compressed by algorithms. The resolution of the final stored pictures will not be as large as the resolution * size. Let's discuss the specific algorithms and processing methods."
After saying that, he pointed to the printing paper on his hand and said, "Scan the format, the 16-open printing paper we use." The size of the 16-open printing paper and A4 paper is at the same level, and it is the commonly used paper size now. This range is enough.
After scanning and compression of a 16-open paper, if the content is not particularly complicated, it will be extremely compressed to an acceptable level. A 15-centimeter floppy disk can store about one to three pictures. Considering the double-sided disk and drive that the comrades are working on now, there are six.
Considering the existence of tapes with larger capacity, it is basically enough to carry and transfer some files with small sizes. The reason why Gao Zhendong values this is that in addition to digitizing some important files that can be directly transmitted, there are also the encryption issues of these files during the transmission process.
This transmission includes network transmission and manual transportation of storage media.
Paper files are difficult to encrypt and decrypt, but digital files are different. For important files, if they are scanned and encrypted, it is difficult for others to obtain any actual content even if they are intercepted or lost. "I understand, that is black and white, 256-level gray level, 50 pixels/cm. Is that what does it mean?" said Gao.
Gao Zhendong nodded: "Yes, this is the core parameter. Another parameter is the scanning speed. I will not stipulate this. You should try to do the fastest you can. What technical means should be used? Think about it yourself and form a plan, and we will discuss it later."
This scanner is destined to be unfair. It is different from the scanners that were very cheap in my previous life. At this time, the scanners had very high hardware requirements. It can be said that they had to install them in a good enough computer to handle them well.
But this thing is not a big deal these days, but is used by important departments. "Okay, we understand." Deputy Director Gao understood what Director Gao meant. He would not provide technology too early or too fast, but instead asked the comrades to work hard and grow on their own, which could also be said to be a painstaking effort.
In fact, this is just one reason, and another reason is that Gao Zhendong doesn't want to spend the money to get it in the system now. He hopes to make this thing well based on his own memory and the efforts of his comrades.
And the technology in the previous life may not be suitable for the present, and there are often opportunities for being too advanced. Not to mention, the broken thing of scanners has never been found in those stores, and it is a niche device.
After getting the new topic, the comrades were very excited, and there was no need for Director Gao to care about the rest. Deputy Director Gao quickly divided two groups based on the comrades' professionalism and expertise, and started working on them.
This is the first shot from the Computer Peripherals Research Institute of Factory 1201, and it must be done well.
When the leaders of the 12th Ministry of Machinery received the report from the Peripheral Research Institute, they looked carefully and laughed.
The most new ⊥小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小� "It seems that Gao Zhendong has great expectations for this. He will stop being a nanny and force his comrades to go on their own."
He must have to deal with things related to Gao Zhendong, and no matter how much the kid pays attention to it, he cannot overestimate it. "I also think that maybe one of these two things is very good-based and the other is narrow in purpose. In the context of not being urgent, he asked the comrades to exercise more by themselves, which is a bit similar to those of JP-59 and XS-59." The chief engineer of the Twelve Machinery Department also laughed. "Well, his consideration is reasonable. We still need to cultivate talents. It is not spring for one branch to stand out, but a hundred flowers bloom all over the garden."
The leader waved his pen very readily and signed his name on the project application report.

"Boss X, when will you start this? We have so many things to say after this battle. We have allocated all the people, just waiting for this day."
The comrades in the army were a little anxious. The battle has been over for so many days, and the summary meeting has not started yet. What if the comrades forget their experience?
The chief engineer of the Defense Work Committee laughed: "Don't be anxious. You are very quick to transfer people, but we are not so fast to mobilize relevant personnel. Comrades from relevant units and factories all have important tasks. No matter how urgent they are, they have to wait for them to have time. Even if they are driven in batches and systems, they cannot be opened in an instant. In this way, one will be opened tomorrow, tomorrow."
"Which one?"
"Let the army start first, they have a lot of things, hahaha." The army is the main force, with the most combat operations, and naturally there are many things.
The next morning, Gao Zhendong sat in the conference room, listening to the comrades talking about the battle process and experience, which made him feel particularly satisfying.
I definitely can't go to the battlefield anymore, so it's okay to listen. This enemy has to let the comrades kill him for him. "... Let me talk about the biggest problem that comrades have reflected in the battle..." A comrade from the army said.
Since it is a summary, it is necessary to say that good and bad things must be maintained, and the best things must be improved. The most important thing is that it must be a bad thing.
I have been used to it for thousands of years, and I have taken advantage of it and wrote three pages after taking a small loss.
This is what the comrades attending the meeting value the most. "The biggest feeling in this battle is the firepower issue."
Many comrades are a little uneasy. How strong does firepower do you need? This time, it can be said that the most change is firepower. Your infantry only has a small cannon. What else do you want?
But no one questioned that everyone has a bit of this disease. It may have been relieved recently, but it cannot be cured, and it will not be cured in a lifetime.
No matter how strong the firepower is, you can always find the areas where the firepower is insufficient.
"Machine gun! The biggest problem is machine guns. Heavy machine guns are too heavy! They can't keep up with the troops at all. If there were not Flight 61, assault rifles could be fired continuously, and guns with grenades, 61 fire, and Red Sword-61 as supplements for offensive weapons, they would often suffer from shooting against heavy machine guns in the bunker."
No, do you want to listen to what you said?
