RPAGF Chapter 856 Hehehe, did you guys think of this method?
Chapter 856 Hehehe, did you guys think of this method?
Is it too advanced?
No way...
Jiang Xia's bewildered expression, as if saying "it's no big deal," made Professor Zhonghua's hands itch to touch her.
The wind was really strong today, making one want to pluck that tuft of hair on his head that was swaying in the wind.
Listen to what kind of words this kid is using.
"Light ruler"?
Any measurement involving "light" is anything but simple!
Professor Zhonghua thought to himself, "This kid hasn't been gone long from Comrade Zu Tong's place, who works on optical instruments. Could it be that he's stolen some kind of secret, new measuring tool?"
He then thought that if that were true, it would be a good thing.
But then Jiangxia suddenly introduced a "voice-controlled" device, which immediately set off alarm bells in the professor's mind.
"Don't think that I, an old man, spent my time abroad for nothing!" Professor Zhonghua recalled the cutting-edge developments he encountered at NACA.
"Before I came back, I heard rumors that they had a lab that was trying to use sound signals to control simple mechanical actions, such as whether sound waves of a specific frequency could trigger a relay switch, or whether different tones could be used to command a robotic arm to execute the most basic commands such as 'start' and 'stop'..."
But those are still laboratory concepts hidden away, and the data may not even be reliable!
You little rascal, you actually moved it right into this workshop and used it?
Could it be?
……
The poor, clueless boy had no idea that Professor Zhonghua was already envisioning a grand technological spy drama. He enthusiastically pulled the professor to the drawing board, picked up chalk and ruler, and began to explain his ingenious idea, which sounded sophisticated but was actually based on the spirit of "using rudimentary methods."
"Our first step is to make an 'optical calibration ruler'!"
As Jiang Xia spoke, he drew a long horizontal line on the board.
“We’ll find a steel rail or an aluminum alloy profile to use as the main reference ruler. We’ll use a machine tool to precision mill milling millimeter-scale lines on it. Our shipyard can definitely do that.”
He then drew a row of thin, vertical rods above the reference ruler: "Directly above each jack, fix a vertical pointer with a sharpened tip. Then, here comes the crucial part—"
He then drew a thick line behind the reference ruler to represent the light source. "Let's put a row of small light bulbs, the kind of spotlight bulbs used on ships or in searchlights, and add a long strip of shade so that the light shines only forward and evenly onto this graduated reference ruler."
Jiang Xia gestured with his hands to illustrate the light and shadow effect: "In this way, each pointer will cast a clear shadow on the ruler under the light."
Before operating, have the soldiers adjust the jacks to ensure that the shadows of all the pointers are precisely aligned with the 'zero' mark on the ruler!
"Isn't this just using the simplest optical magnification principle to achieve precise alignment of the initial positions of all the lifting points? It's much more accurate than estimating with the naked eye!"
Upon hearing this, Professor Zhonghua's furrowed brows relaxed slightly. It turned out that the idea of using projection to magnify and unify visual benchmarks was indeed feasible.
"What about 'voice control'?" the professor pressed, unable to imagine how "voice control" could be implemented in this workshop.
“This is even simpler!” Jiang Xia smiled and drew a simple cam and switch structure on the other side of the drawing board. “We don’t need to make such complicated electronic gadgets. We’ll just find an old, discarded motor and drive a self-made constant-speed cam. Every time the cam rotates, it will open a flexible electric switch once.”
He then drew a few lines: "This switch controls two circuits at the same time: one circuit connects to a high-powered tungsten iodine lamp, which is hung high in the workshop and flashes towards all the operators; the other circuit connects to an electric bell, the kind used in our telephone team or on ships."
“The motor rotates at a constant speed, and the cam periodically turns the circuit on and off,” Jiang Xia simulated the cycle with his hand, “and the result is that the tungsten iodine lamp and the electric bell light up and ring at the same time and in the same rhythm! ‘Light on and bell ring’ is an action beat, and ‘light off and bell off’ is a preparation interval.”
We can control the lifting speed by adjusting the motor speed, for example, setting it to one beat every ten seconds..."
So, the final process is as follows:
The light source was activated, and all soldiers adjusted the jacks until the projected tips of their respective pointers all pointed precisely to the zero line of the ruler.
Once the 'sound and light metronome' is activated, the soldiers strictly follow the rhythm of each 'light on and bell ring', rotating the handle at a fixed angle synchronously and evenly at each beat. Of course, the corresponding lifting amount for this angle needs to be tested in advance.
Then, pause every few beats, say five!
Use the 'light ruler' again to check if all pointer projections are still on the same horizontal line to ensure there is no accumulation of errors. If a deviation is found at a certain point, make fine adjustments to correct it individually.
Repeat the above steps until the core casing is smoothly separated.
puff……
"I thought it was some kind of mysterious thing, but it turns out it's just optical projection positioning combined with synchronized sound and light command! I thought you could actually make a ruler out of light..."
"Uh, there really is. But that ruler is still missing a few parts, otherwise I wouldn't have gone through all this trouble..." Jiang Xia thought to himself as he finished the last stroke of the sketch.
Professor Zhonghua, unaware of Jiang Xia's thoughts, looked at Jiang Xia's hand-drawn sketch with a speechless expression.
That's it……
This……
This actually seems to work!
"Brilliant! Using light to solve the problem of 'seeing accurately,' and using a unified rhythm of sound and light to solve the problem of 'moving in unison'!"
So that's what you mean by 'voice control'—it doesn't mean recognizing speech, but rather providing unified command signals!
Although this method still relies on people at its core, it provides them with unified instructions and judgment criteria!
"You're really getting better at 'adapting to local conditions'!"
Professor Zhonghua patted Jiang Xia on the shoulder happily, "Alright, go have some fun. I'll call you over when the conditions are finalized!"
"Oh, by the way, my wife isn't here right now. When she gets here, I'll have her make you some steak..."
After saying that, Professor Zhonghua took off Jiangxia's sketch, put it in his pocket, called to the students who had come with him, and ran back to his office not far away.
After the professor left, the staff officer who had been quietly waiting walked solemnly to Jiang Xia, stood at attention, and gave a standard military salute.
Then he took out a gleaming silver badge from his briefcase and carefully pinned it to Jiang Xia's chest.
Jiang Xia looked down at the badge. Unlike common medals, it was a deep sea blue, with the outline of a warship cutting through the waves embossed in the center, and the edges were surrounded by a combination of olive branches and gears. The material was heavy and the workmanship was extremely fine.
"Huh? These are special naval badges?" The kid was a little stunned. Special badges from the navy, land, and air forces? He's collected them all?
"This badge came so easily?"
The staff officer was amused by his reaction and shook his head repeatedly: "No! No! This is a special pass badge for our North Sea Fleet, it's far from what you're talking about."
He paused deliberately, watching Jiang Xia's expression instantly collapse, then added with a smile, "But with it, you can move freely throughout the entire base. The commander specifically instructed that even if you sneak into his office to take a nap, the sentries won't stop you."
After saying that, he saluted again, turned around, and quickly followed in Professor Zhonghua's direction.
