In the communication area, in front of several base stations for display, Mr. Nie watched it for a long time but didn’t know what the use of this thing was?

A big and thick iron cabinet?

Can you communicate through this?

Confused!

After wandering around the base station, Father Nie asked in confusion: "How do you communicate this thing? Can you demonstrate it?"

"It's not possible yet, the mobile device has not been built yet." He Ku shook his head awkwardly. The railway's communication system is too complicated to demonstrate, and there is no condition here.

Generally, it is used when the vehicle and the dispatch room are remotely communicated, and when the train is uploaded on the backend of the train, and all of them are made of these equipment and do not have communication functions.

But after thinking about it, He Ku thought of the small toy he created a few days ago. Perhaps this could be used as a communication prop temporarily.

"Wait, I thought of it!"

He said to himself and rushed to the office without looking back.

"Dad, why don't we go and have a look?"

"Let's forget it, Xiao Ku has no shadow now!" Looking at the disappeared back, Father Nie shook his head helplessly and opened the iron cabinet at the base station.

In an instant, the two of them took a breath of air conditioning at the same time.

I saw the PCB boards of the communication module and the antennas of the shell connected to each other, neatly and densely packed troubles in this iron cabinet. The overall layout makes the scalp numb.

If it weren't for opening it, who would have thought that there were so many things in the silly and thick cabinet!

In the office, why bother rummaging through boxes and cabinets, find out your own game works, and take aerial photos of drones!

Then, He Ku took out a 3g transceiver module in the drawer and soldered it to the location of the original radio communication module of the drone and the control box.

In this way, the drone can use 3g signals to achieve remote transmission.

After doing this, why bother to take the drone back to the communication area and prepare for the demonstration?

Across a distance, Mr. Nie saw He Ku holding a black box in one hand and a small plane in the other.

This plane is a little strange, with four propellers.

Mr. Nie took the drone and was confused, "What's this thing? A four-propeller aircraft?"

When you pull the propeller with your hand, you can still move, and you can vaguely see the small motor inside.

He once bought a model of Eagle Sauce to refer to the research. Although the workmanship is much worse than this, the nature of the two is probably the same, giving children time to spend time.

Nie Xiaoya was also blocking the drone in her father's hand with her toes, and was also confused.

Didn’t you say that you should test the communication base station? What should you do with this toy?

"Give me a little first and install a camera." At this time, He Ku had already opened the control suitcase and took out the removable camera.

"Camera?" Seeing what He Ku's hand, Father Nie became even more confused.

Outrageous, simply outrageous.

However, when he saw a small screen inside the suitcase and the operating rod, he had a bold guess.

Could it be that this plane can fly?

Buzz...

Before I could ask, I turned on the switch on the drone. In an instant, the four propellers worked at the same time, allowing the drone to park steadily in mid-air.

At the same time, Nie Xiaoya and Nie Father Shuai keenly discovered that the black screen inside the suitcase had actually lit up.

The picture is exactly where I am waiting for others at this moment.

"Then let's start."

Hearing He Ku's voice, Father Nie hurriedly gave up a seat so that He Ku could control the suitcase more conveniently.

He is almost certain now that the toy plane just now can fly and also transmit pictures.

This is so amazing!

You should know that even the U2 high-space spy drone of Yingshang cannot transmit the images they monitor in real time, and can only be recorded through film so that they can be viewed through other devices when returning.

And this little toy can actually teleport in real time, which is really terrible!

At this time, He Ku had already operated the drone to fly into the sky, and the controllable aerial camera turned the lens downward, monitoring the location of the exhibition area in real time.

Even Coach Nie can see the flow of people in the exhibition area.

"You see, this drone is now using our second-generation communication technology. The images captured by the drone are transmitted almost in real time."

"Because the current camera quality is not good, the second-generation communication number can transmit video data without pressure!"

"Of course, in addition to this second-generation communication technology, we also reserve the third-generation communication technology and are studying the fourth-generation communication technology!"

"Ah? This!"

Father Nie was so stupid!

Use one generation, reserve one generation, and develop one generation!

Is this a thing that people say?

"This!" Nie Xiaoya was stunned for a long time before asking incredible question: "Don't the camera can only record the picture through film? Why can this drone bypass the rubber ring, record and transmit the picture directly?"

"Digital technology! Nothing fuss." He Ku finished speaking, signaling the two of them to control the drone at will.

"Is it really possible?" Nie Xiaoya asked, and she had already started to control the remote pole in her hand.

In an instant, the picture of the drone can be seen moving with the naked eye!

But this picture is not as clear as it is when it is still.

The camera is the bottleneck of this drone.

Upward, downward, left, and right, Nie Xiaoya aimlessly controlled the drone movement, and was very excited. It turned out that there was such a toy!

At the same time, the drones in the air are also swaying left and right under this extreme control, but they can always find a balance.

But Father Nie's brows were not as stable as the drone, but the wrinkles became deeper and deeper. He watched the drone perform various difficult movements in the air, and couldn't help but sweat for it?

Isn't it really going to overturn the machine when playing like this?

Buzzing...

As the drone flies lower and lower, many people can already hear the noise from the four propellers.

They raised their heads in confusion and saw the drone with a camera on their foreheads, and they burst into a cold sweat!

"Damn it! The enemy attacks!"

"What's going on? How come there are planes?"

"Catch it down! I didn't expect that the enemy's plane had already flown in, and we didn't even notice it!"

...

While screaming, the sound of everyone talking came from the suitcase!

Previously, the drone blocked its own noise because it added a sound filter system. Now, once someone talks, it can be transmitted immediately.

Now, Nie Xiaoya was also confused. She didn't know why the plane she was flying suddenly became an enemy plane.

"It's not like that, I'm an intermediary!" Nie Xiaoya explained anxiously.

The drone above everyone's heads also made the same sound.

Now, everyone reacted and breathed a sigh of relief: "Good guy, it turns out that it is also your Xinye thing!"

"I just said how small things can fly to us so much? It turns out that you are the ones who are controlling them!"

"What's wrong, what happened?" Director Yang suddenly felt an uproar when he saw this and hurried over.
Chapter completed!
