Chapter 312 308. Here Comes the Little Flying Stick

The ninth day of the lunar month.

Engineer Yang worked with engineers sent by the drone manufacturer to connect the smart agriculture data processing system with the drone.

The tenth day of the lunar month.

The official test begins.

An operator opened a box in his hand that looked particularly high-end.

A palm-sized black drone was taken out from it.

Although this drone is small, it is equipped with two optical cameras and six spectral cameras.

Under the control of the operator, the drone took off tremblingly, flew to about five meters in the air, hovered for a moment, then whooshed into a wasteland that had not yet been cleared, and quickly disappeared.

"It's flying now, what can it do?" Li Zheng, who was watching the fun from the side, asked curiously.

Luo Yihang kept it a secret, "Just wait and see, we'll know soon. It can solve all the problems you mentioned before the New Year."

Li Zheng curled his lips, obviously not believing that this little thing could do anything, but he still stretched his neck to look into the field.

About ten minutes.

The little plane came back with a buzz.

Luo Yihang stepped forward and asked the operator, "Have you collected all the data?"

"We've collected it, and will send it back immediately." The operator replied without even looking up, tapping the controller in his hand a few times. "The control center has received it."

"What are we collecting?" Li Zheng muttered to himself as he glanced at the controller screen. He saw a colorful field that could roughly be seen as the shape of the farmland he had just flown over.

"This is a spectral image." Luo Yihang answered simply.

Before I could finish the explanation, I heard the operator shout, "The data has been transmitted back and has been synchronized to the plant protection machine."

"Okay, Brother Li, start working first. Yours and mine." Luo Yihang directly captured the able-bodied men.

Li Zheng was inexplicably directed to the large drone at the back, and imitated Luo Yihang to pour the prepared powder into the can on the back of the drone.

The only difference is that Li Zheng poured red, while Luo Yihang poured blue.

Once filled, replace the lid.

Step back.

Under the control of two operators, two huge drones, each nearly three meters long, were seen with six propellers spinning in unison.

A cloud of dust rose.

Slowly rising into the sky, it flew towards the barren fields.

This time the drone is big and can be seen.

Li Zheng looked at the one he had loaded with powder. Not long after it flew into the field, it began to circle around one place. At the same time, the drone began to spray powder from the bottom, as if it was drawing a circle. Then the nozzle was turned off, and it flew straight to another place, continuing to spray powder in circles.

"What are you doing?" Li Zheng didn't understand at all.

"The downwash airflow of the propeller is used to enhance the penetration of the powder. Under the effect of the powder's own weight and air transmission, the powder can be evenly scattered and effectively prevented from drifting."

The operator answered very fluently and accurately, then looked at Li Zheng with a confused look on his face and pretended to nod, "Oh, oh, so that's how it is."

Luo Yihang held back his laughter and continued, "This is marking. The blue ones are rocks underneath, and the red ones are muddy ground, which is easy for vehicles to get stuck. Use the colors to mark them, so that when tractors pass by, they can hide there and people can go in to clean up."

After hearing this, Li Zheng understood.

And I immediately realized how convenient it was to have markings.

The tractor won't get stuck, and its cutter won't be damaged by rocks. It can just turn a corner and chug along.

We have to dig stones and drainage ditches manually. At most, we can dry them in the sun for two days and then come back to do it again.

When using a tractor to clear wasteland, the actual work time is less than half. The remaining half is spent pulling the tractor out of the mud and changing cutters and tools.

With this mark, efficiency can be increased by more than three times.

"Hey, how does it know where there are stones and where there is mud? It seems that they don't have any control." Li Zheng became even more curious.

"The little plane just flew around and took these photos. There's a spectrum on it. The rocks, mud, trees, and grass all have different colors. After it's transmitted to my data center for processing, everything in the field will be clear."

"As for why it doesn't need to be controlled, it's because it knows the way by itself. The path is automatically planned. It flies and sprays colors by itself. There's no need for human control at all."

Li Zheng was stunned by this explanation. He was amazed. "Technology is so advanced now. It only flew a small circle for about ten minutes. How much area did it capture?"

"Two hundred acres!" The operator answered immediately and gave Luo Yihang a resentful look, as if blaming him for robbing him of his chance to popularize science...

After that, the land reclamation immediately entered the fast lane.

The process became like this.

First, a group of workers went into the wasteland and walked around carefully looking for bird nests, bird eggs and small animals.

There are too many wild birds in Tianhan, and one of them might lay eggs in early spring. Therefore, it is essential to dig out bird nests when reclaiming land.

So much so that Officer Yuan almost became a permanent resident in Ping'angou.

After cleaning out the bird's nest, a small surveying plane will fly in and collect data and send it back to the data center.

After processing by the data center, the route and location are planned and transmitted to the plant protection drone.

Two agricultural drones flew up to spread paint and draw marks.

Then a large tractor with a roller cutter went down into the field, rumbling along, and turning when it came to a sign.

After a large area has been cleared, workers will come in to remove the stones in the marks and dig ditches to drain the accumulated water.

At the same time, the tractor removed the roller cutter and replaced it with a deep tiller to break up the bottom plow layer, and then deep plowed and rotary tilled the soil.

Before rotary tillage, hang up a fertilizer spreader, spread the organic fertilizer, and then till the field.

Till the soil back and forth two or three times.

Then dig ditches and build ridges.

Manually trim the corners.

Go through the normal land reclamation process.

After all these processes are completed, the stones and accumulated water should have been dealt with, and then we can finish off these scattered places.

Some small pieces don’t even require a large tractor and can be cleaned up directly with a small hand-held machine.

As the coordination becomes smoother, the speed also increases.

So much so that throughout the entire process, the most time-consuming part was actually finding the bird eggs at the beginning.

After becoming familiar with the high-tech instructions, the pioneers brought by Li Zheng all suggested, "It would be great if your little plane could find bird eggs."

Engineers from drone companies should listen to the suggestions of front-line operators.

I actually came to the scene and started researching, wondering if I could add a function to the optical camera to mark the bird eggs in the grass.

However, the environment is complex, and many bird nests are in the grass, which is obstructed and may not be visible optically.

I started to study whether to add a thermal sensor, but bird eggs are too small and need to be very sensitive.

What about the grass over there? The grass has moisture. Can we combine the spectrum and thermal sensation?

Anyway, the research is quite complicated, and a string of nouns come out of the engineers' mouths.

Officer Yuan felt a chill on his back when he heard this.

Stop it immediately.

"Wait! Wait! Don't do that. It will be very troublesome if we develop this function."

"What's wrong?" The engineer didn't understand.

"What's the trouble?" The workers didn't understand either.

It's obviously a good thing to reduce the workload.

"You guys are going to sell this plane after you develop it, right? What if a bad guy buys it and goes to the mountains to look for bird eggs, uses them for poaching, and destroys the ecology? That would be troublesome."

"Ah!"xN
No one really expected this to happen. Forest police are forest police and they are very thoughtful.

The engineers also began to struggle.

We now find that there is indeed a demand in this regard, and the technology seems to be feasible.

But they may be used for poaching, so we have to be on guard.

Forget it, report it to the company and let them study it.
