Hear the battery,

Wang Fan's heart moved, as if he had thought of something, but he still had a little doubt in his heart:

"What are the functions of the small plane you designed, how can the ordinary power supply not support 1/3 of the time range."

"Even if the consumption of the plane is relatively high, this is a bit abnormal."

"I think about it, a little bit more."

Tao Wei folded his fingers and counted them one by one:

"Ultrasonic sensors, this is used to measure distances."

"Laser sensors, like ultrasound, are precise at distance."

"Optical sensors, transmit images, build remote sensing images."

“…………”

Tao Wei jumped out of his mouth in a series of eight sensors, and by the way, he also explained the application of each sensor in the airplane.

After hearing this, Wang Fan was numb, and the answer came out.

Boy

No wonder the power supply is not enough.

The dare problem is here.

Eight sensors were directly hung up, and the stupid son of the landlord's family didn't dare to play like this.

With such a large energy consumption,

It's strange that ordinary power can be brought up, and he scolded the owner of the Taobao store, and the owner of the other family doesn't know what is wrong.

In general,

Like this kind of small aircraft, they only have two sensors and a set of drive system, and they are generally small aircraft.

And Tao Wei's is obviously not ordinary, it is clearly the plus version.

Eight sensors,

Even if it's a group of four, you have to use two drivers.

After all, optical and ultrasonic, remote sensing ranging and other sensors belong to two completely different types, and the gap is too large.

If you use the same drive system, it can be, it is nothing more than the problem of multiple interfaces in the program, but then the total control system, that is, the STM32 microcontroller, faces a very large operating load and is easy to go down.

"That's not going to work either."

Tao Wei listened to Wang Fan's words and said with a heart:

"It cost me more than 100 yuan, and the boss swore to me that the graduation project was absolutely fine, and I had to have a good fight with him."

"It's not that I said, the energy density of batteries right now just doesn't work."

"It's too low!"

Tao Wei extended the topic, looking worried about the country and the people:

"Take the most advanced DJI drones and BYD cars in China, which use batteries as the main energy source, the former, the best series of drones can only fly for 55 minutes when fully loaded."

"Although the latter has a blade battery as a load, the battery life still can't exceed 700 kilometers, if you encounter extremely cold weather, you have to make a discount on the original basis, 700 kilometers can have 400 kilometers is good."

After complaining a few words, Tao Wei patted Wang Fan:

"Wang Fan, you are making energy materials, and I will have to rely on you in the future."

"When will a new material be developed to solve all the above problems at once."

"I think the research direction of your graduation project is very good, that level of material, once there is a result, it will be a world-class discovery, and I will be able to get some light behind my ass when the time comes."

The more Tao Wei spoke, the more energetic he became, and finally learned from the appearance of Water Margin Liangshan in the TV series, and hugged his fists: "Gou Fugui, don't forget each other." ”

Wang Fan: "Dogs are rich and noble, and they are looking at each other!" ”

Then, Wang Fan walked into the room, and in Tao Wei's unclear gaze, he took out a silicon carbon anode material battery:

"Try this."

"See how long it can run?"

Tao Wei's face was full of questions, and he looked at the black thing on the table like a stone:

"What is this?"

"Don't tell me it's a battery."

"Congratulations, you got it right!"

"It's really a battery, I've never seen such a strange battery in my four years of college."

Tao Wei was a little surprised, a little unexpected.

But this is not to blame him, it is really a handmade battery that does not look good, like freshly cooked black charcoal, and there are white lines, I don't know where I think it is garbage.

"Where did you get such a strange battery?"

"Don't ask where it came from."

"If you have time to go back, record its usage data."

"Maybe I'll be able to use it."

Wang Fan said with a smile, taking Tao Weihui as a tool.

"Will this work?"

"Don't plug it in, it's embarrassing if you can't even move the propellers of the plane."

"I might as well not save the 100 yuan and buy a new one."

Tao Wei was a little skeptical.

Wang Fan patted Tao Wei on the shoulder: "Believe me, it will surprise you, remember, record the usage data." ”

Listening to Wang Fan's words, Tao Wei took the battery back that night, plugged it into his small plane, and began to do experiments.

What he never expected was that

From eight o'clock to eight o'clock to eight o'clock.

The performance of the aircraft is still fully loaded.

"Awesome, Brother Fan."

"Where did you get the battery, if you calculate the energy density per unit volume, it has almost caught up with the domestic first-class level."

tested for a while,

Tao Wei directly took out his mobile phone and called.

Wang Fan: "How's the data?" ”

"I've been testing for half an hour, and I'm still at full performance."

"It's never been better."

Tao Wei replied immediately.

“ok！”

"Remember to send me the data before the end of the night."

"You can keep doing it." Wang Fan was not surprised by this result, and according to the actual performance, it was only half an hour to get it.

"Can you keep going?"

When Tao Wei heard this, he was even more surprised, and then he took a private look, and after finding that there was no one, he lowered his voice and asked secretly:

"You kid shouldn't have taken it out of the scientific research results of any teacher in the research group?"

"Such excellent data, don't be discovered at that time."

"We're both going to have to suffer!"

Wang Fan smiled and said with great certainty: "Don't worry, nothing will happen." ”

"Don't worry, use it boldly!"

"I'll cover you for something."

The voice fell,

After being injected with a heart booster, Tao Wei had no scruples.

Listening to Wang Fan's affirmative tone,

He even wanted to play something big.

"Brother Wang, lend me your data port."

"What?"

"I'll burn the program again."

"Burn the program, didn't you control the system program already included, why do you want to burn it again?"

"I'll burn a new, Plus version!"

Tao Wei said as he looked at the small plane on the table with a feverish look.

New control program system,

Some restrictions on the hardware will be lifted to maximize its performance.

To put it simply, it's loaded.

"In my drawer, take it yourself." Brother Wang replied.

"Okay!"

After a few minutes, Tao Wei, who had prepared everything.

New tests have begun.

10 minutes ......

20 minutes ......

40 minutes ......

An hour.........

The further back he tested, the wider Tao Wei's eyes widened.

It's incredible!

Even Brother Wang, who had been busy with his own affairs next to him, asked:

"Tao Wei, if I'm not mistaken, you don't seem to have changed the battery after re-copying the program, where did you get the battery, so it works?"

"I haven't changed." Tao Wei immediately shook his head.

"Nima, it's been more than an hour since the beginning!"

"I haven't changed the battery once."

"I also re-entered the new plus version of the program, where did you get this monster battery?"

"The energy density is so high?"

Brother Wang's voice suddenly increased, and his words were full of shock.

meanwhile

Before the two could finish speaking, there was a knock on the door.

Tao Wei opened the door and looked.

I was stunned for a moment.

Because it was none other than the head of his own education department standing at the door, and there were two other staff members wearing the uniforms of the government department.
