775: C775 Visiting the Measurement Ship

C775 Visiting the Measurement Ship

This Surveying Vessel, although publicly claimed to be for civilian purposes, however, the people on it were all from the navy. Many of them were wearing the navy's white sailor uniform. They were busy on the screen in front of them. When they arrived, they felt a sense of urgency.

"We all said that one minute on the stage, ten years of hard work under the stage." As they walked, Colonel Chen said to Qin Guan, "Our Surveying Vessel on the sea shoulder a huge task. Therefore... We have been studying and practicing. "

Qin Guan nodded. "Comrades, you have worked hard."

When they were on the sea, they only used a few minutes of time when the satellite flew over their heads. They needed to control all the data they needed. Now, they needed to control the target. Because it was falling, the time it took to control the target was even shorter.

Going out to sea often took a few months, but the most effective ones were the few precious ones. Of course, they could not let anything go wrong. What did they have to rely on? Of course, he would start to practice continuously right now and formulate various proposals.

The Oceanic Control Department had already started preparing for this very early on. All equipment had to be "zero malfunctions" set off, and no problems were allowed. All equipment had to be checked and repaired at the base pier.

However, this still could not be guaranteed. On the distant sea, once there was a problem with the equipment, there was no other way to get help, and they could only rely on their own strength to solve it.

Therefore, there were no idlers on the ship. They had to be people who were proficient in their own equipment. At crucial times, not only did they have to know how to use it, they also had to know how to repair it.

Qin Guan stood behind a row of control platforms. Seeing everyone practicing nervously and shouting slogans, Qin Guan could not help but ask, "This ship of ours needs a computer, right?"

The development of national defense could not be without a computer. The first nuclear bomb that exploded in Han Country relied on a hand calculator to calculate for a few months.

After that... After that, Han Academy of Sciences established a computer institute and started to work on computers. From 1956, they started to develop the first generation of computers. In 1958, they successfully developed the first small electronic tube computer, 103 computer. In 1959, the 104 computer was successfully developed at a speed of 10,000 times per second. This was the first large universal digital computer developed by our country. Its main technical indicators surpassed the computers in R Country at that time, and compared to the computers developed in Cattle Country at the same time, it had the fastest computing speed. It was not inferior at all.

The development of large scale computers in Han Country was not slow.

In 1965, they started researching the third generation computer, and in 1973, they successfully developed a large scale computer with a circuit with 150 computers. 150 computers were 48-digit long, and their computing speed reached 1 million times per second. It was mainly used in oil, geology, weather, and military departments. In 1974, a DJS series computer with integrated circuits as the main component was successfully developed.

For aerospace control, it had to follow the satellites in the sky. Of course, it required a very high computing ability. Now, after hearing Qin Guan's question, Colonel Chen said, "Yes, under our feet is the 013 machine that we developed by ourselves. Its calculations have reached 10 million times per second."

The computer was the brain of Distance One. In the process of development, the control ship used the 013 series computer that was developed in 1976. This kind of super computer's computing speed was not bad.

Hearing Colonel Chen say ten million times per second, even Qin Guan nodded." Not bad, not bad. "

At this moment, suddenly, a technician stood up and shouted, "The computer is malfunctioning, the data cannot continue to be calculated!"

When he heard this voice just now, even Colonel Chen was stunned. "What's going on?"

"I don't know either." The person pointed at the screen in front of him. At this moment, the screen was synthesizing a control curve. This was the result of a simulation experiment. However, the control curve behind it could no longer be displayed.

Next to him, on a monitor, the numbers were constantly jumping and flashing. However, it was not normal.

"Immediately eliminate the malfunction!"

At this time, Colonel Chen could not be bothered to call Qin Guan. This ship had just gone out to sea. This was the first time he was carrying out a mission, especially now. It seemed that the mission would be officially launched soon. Who would have thought that at this moment, a problem would arise?

If the computer couldn't work normally, then this task wouldn't be completed. Although this time, in order to get back up, and to test and control ship # 2, however, if they didn't get any results this time, it would be a disgrace to everyone.

They were very anxious.

Colonel Chen started typing on the keyboard, hoping to find the fault, but it was useless. There was no reaction at all. The computer was out of control.

"Lisa, Lisa." Qin Guan suddenly felt the benefit of having a back door. He could find Lisa at any time, and Lisa would definitely be able to sense everything he saw.

After a while, Lisa's lazy voice came. "This is a hardware malfunction. It should be some components that are welded and have bad contact."

"Then what should we do?"

" When the next big storm comes, it might be fine. As for the specific welding, I don't know. I have to disassemble it and see it piece by piece. "

"Alright, let's get to this point. I'm going to hold a meeting. Our progress is very smooth. There will be a surprise when you come back."

Lisa cut off the line unilateral.0

Lisa busied herself with her work, while Qin Guan could only wait here. Seeing everyone continue to operate on the keyboard, Qin Guan finally opened his mouth. "Colonel Chen, could it be a circuit malfunction?"

Computer malfunctions were divided into software and hardware. Now, everyone wanted to solve the software problem, but no one had ever thought about hardware problems.

Qin Guan said it was a circuit malfunction.

Hearing Qin Guan's reminder, Colonel Chen suddenly understood. "Yes, it might be a problem with the third cabinet. Let's go down and look for it one by one!"

If there was a hardware problem with the computers in the future, it would always be a matter of what was broken. There was no way to fix it. But now, they could only fix it.

Furthermore, there was no way to change it.

Following everyone, Qin Guan entered the cabinet below. The air conditioner inside was rumbling as it spun. The countless cabinet was dazzling to the eyes.

Colonel Chen opened one of the cabinet. The densely packed lines made Qin Guan's scalp tingle. It was only at this moment that Qin Guan suddenly realized how far behind this thing was.

Listening to the data, it sounded very advanced. It was ten million times per second, and soon it would be a hundred million times. However, this computer was completely manually assembled.

That's right, it was manually assembled. The densely packed lines inside were all manually welded.

Looking at the huge welding tin particles, one could tell that the craftsmanship was limited. There were even traces of pine incense on it, but they didn't even know to clean it. It would be a miracle if there were no problems with such a circuit board.

The A.I. Chip on it also marked foreign words.

When it entered the late 70s and the 80s, due to the lagging of the chips in China, the domestic computers had already started to purchase the super-large-scale integrated circuits produced overseas.
