Siheyuan: Starting from a fitter

Chapter 165 Fetion
The motherboard was finished, and the next step was welding. Yan Jiefang took it upon himself to weld six control motherboards.

"Yes, the next step is testing, the focus is on the various parameters of NOR FLASH, which must be fully covered," Li Guocheng instructed.

"Okay, Brother Li. By the way, Zhang Zhijing just informed me that the 485 bus has been tested. Let's go over and take a look."

Yan Jiefang handed the six boards to his team members, and then remembered the 6 bus.

Li Guocheng and Yan Jiefang came to the software group. As soon as they entered the door, they saw the three of them sitting at their desks, staring at the screen and giggling from time to time.

When Yan Jiefang was about to give a warning, Li Guocheng reached out to stop him.

On all three computers, there is a small pop-up window, which is an improvement over the previous flat structure, and the send button has a little 3D rendering meaning.

Everyone thought correctly. What they were playing was the small task assigned to them by Li Guocheng, the real-time communication applet: Fetion.

After watching for a while, Li Guocheng gently patted Zhang Zhijing's shoulder.

"Ah, it's Brother Li! We are testing the Fetion program and network communication performance," Zhang Zhijing said excitedly.

"What is the specific situation?"

“The network can connect up to 36 units, with a communication rate of 100Kbs, and the maximum connection distance is 10 meters. If the communication rate is 10Kbs, the maximum connection distance can reach 100 meters.

Fetion, you have also seen that we only send text, and the maximum delay is 3 seconds. If 36 units work together, the maximum delay is more than 10 seconds."

Li Guocheng thought for a while, "The 485 bus is still too slow. We should consider special chips in the future. The current CPU is just like this. But it is enough for now. It just transmits some text data, which is more economical than a hard disk."

Cancel the relay, it is of little significance, and consider using hard drives or dedicated memories for long-distance communications."

When Li Guocheng returned to the office, he thought about whether to consider developing Ethernet now. The 7-layer structure will be known to all engineering college students in future generations, but Li Guocheng has long forgotten the specific details.

But if you are developing a network, there are definitely not enough people. "Forget it, I will study the theory myself first. There are too few people in the software team. Let's continue optimizing the operating system and developing applications."

In early July 1969, exactly three months later, Xiao Bing ran to Li Huaide's office early before Li Guocheng notified him.

"Thank you, Mr. Xiao. Here are six samples. This is the instruction manual. There is also an example program for communicating with the Dawn 6 computer," Li Guocheng said while introducing the information on the table.

"Oh, by the way, let's develop a gadget and see if it's useful to you? Let's go to the lab and demonstrate it directly." After that, he stood up.

Xiao Bing carefully put everything into the bag, carried it on his back, and followed Li Guocheng to the laboratory.Li Huaide also followed with interest.

He led the two of them to Zhang Zhijing's back and explained to her the purpose of their visit, "Director, Mr. Xiao, you guys are watching here, I'll go back to the office first."

With the two people looking blankly in their eyes, Li Guocheng quickly returned to the office and typed directly into Fetion, 'Director, Xiao Bing, hello! '.

Under Zhijing's reminder, the two saw the message in the Fetion communication box, and looked at each other with blank faces.

"Two leaders, what do you want to say?" Zhang Zhijing asked.

"Li Guocheng, is that what you said?" Because Director Li knew Li Guocheng, he quickly reacted and tried to say something.

"Yes, I say hello to you from my office!".

"Xiao Zhang, start driving and let me try." Li Huaide felt itchy.

Xiao Bing reacted and ran to Li Guocheng's office.

"Xiao Li, I'm Li Huaide, hello!" Are you familiar with it?In the early days of a certain chat software, everyone used it to chat in such an awkward manner.

"It's me, I'm in the office and want to say hello to you!".

"Have you eaten?" Li Huaide continued the awkward conversation.

"Hello, Director Li, I am Xiao Bing, I ate it!".

"It's Mr. Xiao, hello!".

"Hello, Director Li!".

. . . . . . .

It's so simple and unpretentious, it's just so nutritious, but this is the daily life of using a certain chat software for the first time at that time.

"This thing is quite interesting. Please get me a set, along with a copy of the instructions and execution procedures." Xiao Bing was still a bit unsatisfied.

"Liberation, please help prepare."

"immediately".

Xiao Bing left with satisfaction, still immersed in the magic of the chat software on the way.

Originally, Li Huaide wanted to connect all the computers in the steel rolling mill, but gave up once he heard the transmission distance.

Li Guocheng recorded his network research on a computer notepad, and now has more than a dozen technologies ready to be developed.

After the design of the operational amplifier is completed, it is time to prepare the chip and test it.The birth of operational amplifiers had a profound impact on automatic control. Li Guocheng wrote an outline to determine the test content, which will facilitate the publication of guide books in the future.

Li Guocheng finished writing the test outline and chip description and handed it over to Yan Jiefang, asking him to design the test circuit board and arrange for personnel to test it.

Three days later, Li Guocheng, who was designing a DAC, was interrupted by a phone call.

"Hello, I'm Li Guocheng."

"I'm Li Huaide, come to my office."

Li Guocheng heard something from Li Huaide's formal tone, and without thinking much, he stood up and walked towards the factory office building.

Knocking on the door and entering the office, what caught his eye were three people standing up, Engineer Xiao and two soldiers, one of whom was wearing glasses.According to the four pockets of the jacket, it shows that they are officers, and the specific position cannot be seen.

"Gong Li, I've taken the liberty to come to visit and ask for something." Gong Xiao stated the purpose of his visit simply and neatly.

"It's an honor for our steel rolling mill to be able to help," which means that he and the steel rolling mill are one.

Li Huaide nodded with satisfaction and subtlety.

"These two are Ma Jianmin and Gong Jiefang from the *** Staff Department," Xiao Gong introduced.

The two soldiers stood at attention and saluted. Li Guocheng quickly stretched out his right hand and shook hands with the two.

"Please tell me the specific situation, two comrades," Xiao Gong said.

"Hello, Mr. Li," Ma Jianmin said politely.

"Hello, Comrade Ma."

"The purpose of coming here this time is to talk to you about the network and Fetion. After our internal testing, we found that Fetion is the best tool for distributed command, but the speed and distance of the network are the bottlenecks.

So I wonder if you have any way to improve the speed and distance of the Internet." After finishing speaking, the two soldiers looked at Li Guocheng expectantly.

Li Guocheng was a little confused. Could it be that history is unchangeable, but Chou Country was replaced by Huaxia.
