"The train has started."
As the cold and dull electronic synthesized sound fell, the two headlights on the front of the car instantly lit up, shining straight ahead.
In the cab, many virtual projections appeared out of thin air, displaying various icons and data that Chen Yu could not understand.
Sitting on the driver's seat, Chen Yu looked at the rows of screens and joysticks on the left and right armrests, and asked, "Isn't there a steering wheel and accelerator?"
"The entire train is operated by touch control." the electronic voice replied.
"Show me how it works."
"Manual mode & smart mode?"
Chen Yu hesitated for a moment: "Manual mode has a sense of control. Let's introduce the manual mode first."
"Yes, conductor. The three-level maglev construction engineering vehicle is divided into two sets of operating systems. Under traffic conditions, the movement method is superconducting magnetic repulsion (EDS). The superconductor at the bottom of each carriage is cooled and interacts with the electromagnetic track. To repel the strong magnetic field, the special long stator synchronous linear motor controlled by artificial intelligence completes the energization of the stator three-phase winding, generates a moving magnetic field that acts on the train's suspension (excitation), and completes traction... "
During the explanation, the artificial intelligence expert also thoughtfully showed a set of dynamic videos.
The video shows the working principle diagram of a long-stator synchronous linear motor. The complex circuit and line diagram contain many professional terms such as pole pitch, stator lamination, stator winding, linear generator winding, and field winding.
I was afraid that Chen Yu wouldn’t understand.
Chen Yu was thoughtful, crossed his legs, and maintained the posture of a wise man, sometimes deep in thought, sometimes nodding, sometimes pinching his chin, sometimes sliding the crystal ball...
"Because the motor has many stages, the number of slots per pole and phase is q=1; in order to facilitate the arrangement of windings..."
“… Since the number of slots per pole and phase is q=1 and a uniform air gap is used, the stator tooth harmonic magnetomotive force is relatively large. Drivers should pay attention to the numerical changes in current density, rated voltage and rated current of the excitation device when applying power… "
"... Standard calculation example: The length of a maglev train car is 23.32 meters, the total weight is 107.6T, the ultra-low speed stage is 400 kilometers per hour, and the running resistance is 60.22kN... "
"... The parameter values calculated so far are: at 75 degrees Celsius and 215Hz, the stator resistance per phase in the 300M power supply section is 0.2886Ω (omega), and the stator leakage reactance is 21... "
[What? What? What?]
[What are you talking about?]
[Sitting in rows under the tree.]
[It’s great, it’s wonderful.]
[devil…]
[Can’t understand, skip it.]
[I always feel that the reviews of UP owners are becoming more and more unfriendly.]
[There are so many things you don’t understand about junior high school mathematics?]
[Isn’t it primary school mathematics?]
[Looking at the anchor’s thoughtful look, he must have understood.]
[Nonsense, anyone who can do technology evaluation must have full professional knowledge.]
[Awesome...]
[Awesome +1.]
Five minutes later, the obscure control principles and methods were finally introduced.
Chen Yu turned his head and looked at Xiao Taohong: "Do you understand?"
"Ah?" Xiao Taohong looked confused.
"well."
Sighing, Chen Yu stood up and patted Xiao Taohong on the shoulder: "You can't always think about playing, you have to study more. Listen to it a few times yourself and try to start it. I'll go out and get some fresh air."
With that said, Chen Yu shook off the non-existent dust on his clothes, walked out of the cockpit with his hands behind his back, and left the camera inside.
After entering the living area and solving three urgent problems, Chen Yu lay on the sofa and rested for five minutes. He guessed that the official people were coming soon, so he got up and returned to the cab.
In front of the crystal ball, Xiao Taohong was still listening to the artificial intelligence explanation with dazed eyes.
"Do you understand?" Chen Yu asked.
"Ah?" Xiao Taohong looked confused.
"Forget it, this knowledge is still too profound for you, take your time." Chen Yu waved his hand and looked at the camera: "More than ten minutes have passed. The introduction of this maglev three-level general construction engineering vehicle has been received. Here it is. Next, let’s start the actual operation and evaluation directly.”
After finishing speaking, Chen Yu walked to the giant car window and looked out. He saw police cars, helicopters, and camouflage jeeps arriving outside, parked densely around him.
Since he was not wearing protective clothing, Chen Yu could not be exposed to the outside world at will, so he instructed Xiao Taohong: "Go to the person in charge outside and bring you your cooperation intention and what the other party has given you."
"good!"
Xiao Taohong nodded heavily, trotted out of the cab, got off the first carriage, and stood on the snow with her hands on her hips: "Who is your person in charge?"
"It's me, it's me! I'm in charge here for the time being!" A young man came over quickly, nodded and saluted: "Hello, madam."
"I am the father-in-law now." Xiao Taohong pointed to the eunuch uniform she was wearing.
"Eunuch...father-in-law..." The young man was stunned on the spot.
"Yeah. What do you have for me?"
Looking at the girl in front of him who seemed to be "not too smart", the young man wanted to make some excuses, but recalling the orders from his superiors, he held it back and handed over the small box in his hand: "For Mr. Wang's cooperation that benefits the country and the people, Thank you very much. Please tell Mr. Wang that the whole of China will unconditionally support his maglev construction plan."
"Okay, I will convey it." After taking the box, Xiao Taohong waved her hand, walked onto the train and closed the door.
"Huh..."
Taking a deep breath, the young man took a few steps back, looked at the train of maglev engineering vehicles, and smacked his lips in envy...
…
"My king, here you go."
"Um."
Taking the box from Xiao Taohong, Chen Yu opened it with his back to the camera.
On the top layer is a handwritten thank-you note with many stamps printed at the end.
He read the thank you letter carefully, put it aside, and picked up the file bag from the bottom.
"Tear!"
After breaking the seal and pulling out the piles of documents in the portfolio, I found that these were detailed construction plans, including location selection, geological structures along the way, excavation difficulty, and other information.
There are three roadmaps, and Chen Yu is recommended to refer to them.
After carefully reading all the documents, Chen Yu chose the second of the three routes, which went directly from Pingchang, the capital, to Puqing, the magical capital, without any transfer stations along the way. Just a straight line.
After making the decision, Chen Yu closed the lid of the box, picked up the route plan, sat on the driver's seat, and said loudly: "Second goods."
"I am here."
"Turn on smart mode and head to Pingchang District in the capital."
"Sorry, your target location cannot be recognized, please select the destination coordinates manually."
Electronically synthesized sounds echoed, and a virtual projection appeared half a meter in front of the driver's seat, showing a flat two-dimensional map.
Chen Yu observed for a moment before finding the right location and clicked on a certain point in Pingchang District.
"Planning a path."
"The path has been planned, but it has deviated from the road surface and is being corrected."
"Boom..."
Along with the loud rumbling sound, the nearly three hundred meter long behemoth began to shake.
Outside the train, everyone felt numbness coming from the soles of their feet.
This is the power of machinery and technology...
"Dong dong dong!"
Half a minute later, rows of crawler chains sank from the originally flat bottom of the train.
The surface of these tracks is raised with sharp spikes to enhance friction with the ground. Inside the crawler track, there are all driving wheels, support wheels, guide wheels, and supporting sprockets.
More like a tank than a train.
"Quack, quack, quack..."
The huge body moves forward slowly under the power of countless driving wheels.
The spiked tracks rubbed against the snow, making a strange sound that made your teeth ache and your scalp numb.
"Is this... still a weapon?"
The young person in charge raised his head, looked at the steel behemoth in front of him, and murmured to himself.
In the cab, feeling the movement of the car body, Chen Yu rubbed his hands excitedly and pointed straight ahead: "Accelerate! Toward the Great Route!"
