Bright Sword Military System

Chapter 1707 Light Emitting Diodes

Another benefit brought by the successful development of integrated circuits is miniaturization and light weight.

The gun detection radar is the most obvious. Originally, it was slightly larger than the rear compartment of a car, and it was a bit difficult to drag it with a car. It had to slow down on the road. After this change, it was only half the size of the compartment.

The one that benefits the most is the tank unit.

Many tank soldiers said before: "The laser rangefinder is easy to use. We can't calculate this and that. The speed is still slow, which is fatal on the battlefield! But as long as the laser rangefinder is turned on like this, it is accurate and fast, and it can always be one step faster than the enemy!"

If it's tank versus tank, being one step ahead of the enemy can be the difference between life and death.

For example, last time, the Eighth Route Army tanks and the devils "Tiger" fought in Xinmin.

The tank crews of the Eighth Route Army cannot be said to be recruits. They have fought and been trained in Yuncheng.

However, the devils driving the "tiger" tank soldiers can use the power of the whole country to select the best crew members from thousands of tank soldiers and then conduct systematic training. Their quality is definitely not comparable to that of the tank soldiers of the Eighth Route Army.

But the enemy and the enemy fired almost simultaneously, and finally the Eighth Route Army won a big victory, all thanks to the laser range finder.

However, its shortcomings are equally obvious.

The tank soldiers complained: "But this thing is often useless. The boss has a box tied to the back. The tank may break down after a few bumps on the road, or a few bullets will hit a few shrapnel... It won't work!"

Therefore, many times tank soldiers do not even carry laser range finders.

Sun Zeming, head of the tank regiment, reported to Wang Xuexin in this way: "The laser rangefinder has too many uncertainties. Many crew members don't want to rely on it psychologically, which will affect their mentality when facing the enemy!"

This statement is also true.

If the laser rangefinder is reliable, then dependence is no big problem.

But if the laser range finder can only be used once or twice... and then suddenly fails, and the gunner has to calculate the distance by himself, the gunner will naturally feel a sense of loss, worry about gains and losses, and even be in a hurry. When he is nervous, his performance may be worse than before.

Therefore, Wang Xuexin agreed to Sun Zeming's request: bring what you want, and don't take what you don't want.

But with integrated circuits, this is not a problem at all.

A box the size of a refrigerator becomes a suitcase-sized gadget in no time, with room to further reduce the bulk.

It is not a problem at all to install this volume and weight inside the tank, so the safety and reliability are guaranteed, and there will be no reason for tank soldiers not to carry it in the future.

However, Wang Xuexin soon discovered that even so, the laser range finder is still not perfect.

This was discovered by Wang Xuexin by accident. One day when he walked out of the headquarters to relax on the playground outside, he saw several guards running around on the playground with a "black box" on their backs.

After asking, I found out that it was a laser rangefinder just developed by the research institute. They sent two to the guards for testing, and the guards did not refuse.

Wang Xuexin took the laser rangefinder and looked at it, staring at the densely packed small light bulbs in a daze.

"What is this for?" Wang Xuexin asked.

"Reporting head!" The guard replied: "This is the reading, the first line is hundreds, the second and third lines are tens and ones respectively!"

Wang Xuexin looked at the labels under each row of light bulbs and understood: In this era, there is no display screen for reading data, and there is no operating system. Reading data is just looking at the light bulbs. For example, if the position of 9 in the first row is on, it is 900, and so on.

Wang Xuexin hesitated for a while, then walked towards the research institute with the laser range finder.

Soon Wang Xuexin knew that he had found the wrong place. Chen Jiefeng was in the arsenal opposite... The research institute was more about solving research problems, and the mass production would eventually have to come to the arsenal. At the moment, Chen Jiefeng was busy with laser range finders and laser proximity fuzes at the arsenal.

When Wang Xuexin found Chen Jiefeng, the first thing he asked was: "The laser range finder has not been put into mass production yet?"

"Reporting team leader, not yet!" Chen Jiefeng replied: "But we have almost tested it, and there are no problems. We plan to put it into production in a few days!"

Chen Jiefeng thought that Wang Xuexin was here to push the progress.

"Take it easy!" Wang Xuexin said.

Chen Jiefeng was taken aback for a moment, then looked at the laser rangefinder in Wang Xuexin's hand and understood: "Head, is there any problem with the rangefinder?"

Wang Xuexin put the rangefinder on the table, pointed to the rows of light bulbs behind, and asked, "Have we always read data like this?"

"That's right!" Chen Jiefeng replied puzzled, "Even Mr. Turing's computer... reads like this!"

Then Chen Jiefeng asked cautiously: "Head, is there any problem?"

Wang Xuexin just said "um" and didn't answer.

There is nothing wrong with Turing's computer reading data in this way, because they are all experts and they are doing research. They even have assistants to help read the data without using their own brains.

But it is different on the battlefield. If the gunner still reads the data in this way, it is unreliable and slow.

It is unreliable because the light bulb is easy to burn out. As long as one is burned out, the reading may be inaccurate. For example, if the hundreds digit is burned out and the target happens to be in this position?This error is big!

The slow speed is not just the slow response of the bulb... It takes a certain time for the incandescent lamp to glow, but it is not easy to detect.

What affects the speed even more is that the gunner reads the data and has a process of looking at the three digits and adding them up, and it is also necessary to determine whether it exceeds 1000 meters.

(There is a separate red light prompt for more than 1000 meters, but this red light is optional, because the gunner can easily tell whether it is more than 1000 meters after reading the data and looking at the target distance)

After thinking about it for a while, Wang Xuexin said to Chen Jiefeng: "Call Comrade Su Liguo here!"

"Yes!"

After a while, Su Liguo rushed over in a hurry. He thought he had made a mistake on the range finder, and Wang Xuexin was asking him to settle the score.

Su Liguo said cautiously: "Leader, is... is there any problem?"

"No problem!" Wang Xuexin still looked at the rangefinder, and asked casually: "Mr. Su has been with Turing for so long, should he be able to make a second tube?"

Su Liguo couldn't help secretly heaving a sigh of relief, it turned out it was because of this.

"Yes!" Su Liguo nodded confidently: "Every step is recorded in detail, and I have made it myself for a while!"

Wang Xuexin nodded in satisfaction. He was very relieved of the dedication of the older generation of scientists.

"Then!" Wang Xuexin said, "It's time to produce light-emitting diodes!"
