Military Industry of Great Powers: Build the Strongest Flanker

The international market price is 50 US dollars per door, and the joint venture price is 200 US dollars per door. Hui Province still bought it?

"The national subsidy is equivalent to one dollar for one dollar. We only need to pay two million yuan. If this continues, foreign exchange will not be able to bear it."

"I originally thought that the price was about the same, and I could use Shanghai Bell. It supports domestic products. But I didn't expect that there were too many problems. During the trial operation, I answered the wrong call. Someone wanted to call the police, but the call was taken to the hospital. I almost missed it. No joke."

Zhao Guoqing gave limited information from Du Chuming to identify possible problems.

"There must be an error in the address book!"

Du Chuming was surprised.

"National Day, you are really amazing. The debugging engineer also said something about the address book..."

"It's not difficult to program a chip. It doesn't require any computing power. It just needs some logic processing!"

Although Zhao Guoqing has never done this kind of project, he can break it down logically from a functional perspective. You call and dial a number, and the program-controlled switchboard connects the line to the target phone through the number you dialed.

This requires the program-controlled switch to have a number mapping table to map each number to the physical address of each phone.

In fact, it is similar to the physical address mapping between the Internet IP address and the network card, but it is simpler than the network switch.

Network computers also need to solve the sending and receiving mechanism of digital information, but program-controlled switches do not. The difficulty is just how many calls can be connected at the same time.

Therefore, if the call was answered incorrectly, it is most likely that the address mapping table is wrong.

This was the first time Du Chuming felt Zhao Guoqing's big breath.

"National Day, although it is not difficult, the technical staff of Hucheng Bell Company are still solving the problem, and there are many technicians from Belgium."

The immediate problem is a mess, not to mention the localization of integrated circuits and chips, which now feels far away.

"Director Du, is this s1240 program-controlled telephone exchange an imported model?"

Du Chuming said: "Yes, China Post and Telecommunications bought two of them at that time, and there were no problems in using them. Then we decided to use the technology of the Belgian Bell Company. This project has been discussed for about five or six years, and Siemens and Panasonic are also in talks." Yes, but only Belgium Bell is willing to transfer technology!”

Zhao Guoqing nodded firmly.

"Two things, one is that our Belgian Bell was deceived, and the other is that the truth is very uncomfortable. If my guess is correct, there is a problem with our domestic components!"

Du Chuming hurriedly asked: "National Day, you come one by one, how could we be deceived!"

Zhao Guoqing sighed, this is also our own problem.

"We wanted technology so much, so Bell of Belgium transferred it to us and took advantage of it to sell high-priced accessories. The more we sold, the more they made!"

Du Chuming was deeply impressed and said: "National Day, how could our leaders not see this? You are right, we want technology so much. We still have to pay the tuition. Tell me about your second thing!"

The second thing is also Zhao Guoqing's personal experience. The durability of domestic capacitors and inductors is so poor. The Hawkeye phased array radar was equipped with domestic capacitors and inductors. After testing it, the machine collapsed!

"Director Du, the working environment of the program-controlled telephone exchange is quite harsh. I suggest that Hucheng Bell Company should replace all the electrical components used with imported ones!"

Du Chuming shook his head and said, "Domestic components cost US$200 per door, but imported ones would probably cost US$300 per door!"

"There's nothing we can do about it!"

How much more money will Belgium Bell make? It is still in the assembly stage with incoming materials. The labor in China is so cheap. Just pay two hundred US dollars for a door. You must know that the international price is only fifty US dollars. This is a huge increase. He came here to kill the people many times!

"Director Du, how much money can we reduce if we solve the problem of localization of chips at Hucheng Bell Company?"

"I don't know, I can lower it by half!"

Zhao Guoqing stopped talking. The lower price is usually one hundred dollars per door. Besides, if we can help Hucheng Bell solve the localization of chips, and then hand over the drawings, 101 may be the same as gallium nitride light-emitting semiconductors. Finally, we will study Loneliness, you have been fooled once, but you cannot be fooled a second time.

"Director Du, we will not be involved in the Hucheng Bell matter!"

"..."

"No...National Day, why?"

Zhao Guoqing made up his mind.

"We're going to design our own program-controlled telephone exchange and let the Belgians eat their shit!"

"..."

Zhao Guoqing did what he said. He held a plenary meeting of Institute 101 to report the situation. He also contacted Ji Hongbo and transferred normative text materials from the International Telephone and Telegraph Industry Standards Association and the Program-controlled Telephone Standards Association.

These are standards set by the industry, and these industry associations are composed of manufacturers or international standards organizations.

For example, the members of the International Programmable Telephone Standards Association are NFC, Panasonic, Siemens and some small manufacturers. They hold regular meetings and submit standard proposals. As long as they are passed, they will become industry standards.

Copies of these documents are free, and these industry associations even take the initiative to promote them in various countries. There is an office of the International Program-controlled Telephone Standards Association in Beijing, and several major telecommunications companies in China are members of it.

It only took three days to receive the regulatory text Zhao Guoqing needed.

"Carrier Telephone Communication Standard", "Programmable Switch Interface Standard and Communication Rules", "International Standardized Communication".

Unlike other technical documents that are all in English or other languages, these standard texts do not need to be translated by yourself. Foreigners have long been kind enough to find someone to translate them into Chinese for you at their own expense.

This saves Zhao Guoqing a lot of things, so he intuitively takes a set to the printing factory to print, and each person has a set of standards.

Zhao Guoqing also studied these normative texts with others every day and organized everyone to discuss them together.

Radar technology and communication technology are connected, and the so-called standards are actually the unified standardization of communication information, interfaces, etc.

Compared with the complicated function integral calculation of radar wave processing, it is really much simpler.

It took a month to thoroughly understand the standards, and Zhao Guoqing organized everyone.

"How about it? Do you have any ideas for the program-controlled phone?"

Xu Guoguang from Institute 607 was the first to stand up and said: "Director Zhao, we have mature cmos chip design technology. We can use cmos chips to store and burn address books. The bus technology can also use 16-bit 1533b data transmission links. , I think there is no problem with the logic chip, it only needs a few judgment statements!"

"Xu Guoguang, why don't you fly? Give me a program-controlled switch using the 1553b data bus..."

Zhao Guoqing was speechless. This guy's plan was still right. You said it was irritating or not.
