Movie black technology

The crimson storm slowly disappeared on the water, and people on the sea completely lost its vision.

Originally, the Central TV station arranged for a follow-up on the bottom of the sea, but now it is raining and the sea conditions are unstable. For safety reasons, it had to be cancelled temporarily.

The crimson storm after entering the water quickly reached the end of the route.

"Master control room, we have reached the designated mission point..." He Chuan habitually turned on the radio report.

After speaking, he realized that the radio communication cannot be used normally under the sea, and the paragraph he just said could not be transmitted back to the main control room.

"We just need to make sure that the instrument is not damaged, record the data of this dive, and then send it back to the master control room after landing." The eldest brother He Xin said at a critical moment.

"Yeah!" The two younger brothers replied in unison, Chen Shen also told them about this, but suddenly forgot it.

Inside the master control room.

Chen Shen looked at the live video, the scene of Crimson Storm diving into the water, almost at the same time when the mecha dived into the water, all the data on the mecha in the main control room was suspended.

But everyone did not panic.

After the mech enters the water, it is normal for the communication to be interrupted.

People in front of the computer relaxed temporarily, waiting for the communication to resume after the mecha came out of the water.

At this moment, Chen Shen suddenly remembered the communication method of the mecha in the movie.

The mecha in the movie can still maintain low-latency and high-bandwidth communications at a depth of seven kilometers underwater. In fact, the technology implicit in these short shots is quite scary.

You should know that, except for extremely long waves, the radio wave communications commonly used by people at sea basically cannot penetrate the distance of 30 meters underwater, let alone seven kilometers underwater.

At present, the most commonly used underwater communication is underwater acoustic communication. To put it simply, the information to be sent is first converted into an electrical signal, and then converted into an acoustic signal. Then the acoustic signal is transmitted in the water to the receiver, and the receiver then reverses the signal. Come and convert and decode, and get the communication content of the sender.

However, this method also has a lot of troubles. Sound waves can only propagate more than one thousand meters per second, slow propagation speed and long delay, large noise in the water, large signal interference and many other problems have always been problems in this field.

If you want to rely on underwater acoustic communication to achieve the effect in the movie, the transmission delay of sound waves is a problem that cannot be solved.

However, it is a pity that the system does not provide a solution for the underwater communication system in the technical data of the mecha, or not directly.

There is only one receiver and transmitter of underwater communication signals in the technical materials of Crimson Storm. It does not directly give the technology of the entire underwater communication system, but only shows the tip of the iceberg.

Because the underwater communication system is an independent huge system, it does not belong to the mecha technology. The only place it is directly related to the mecha is the signal receiver and transmitter installed on the mecha.

The system will not give anything that has nothing to do with the project technology.

By relying on these two signal receivers and transmitters, Chen Shen probably deduced that behind these two devices is a space-based system.

An information communication system based on satellite transmission.

However, this inference did not help him restore the entire system immediately, so in the initial technical outline, he deleted the underwater communication system of the mecha and waited to add it later.

No need to worry about this.

Anyway, if you need to dive seven kilometers deep into the sea, you can borrow their underwater high-speed communication system from the Qianlong project next door.

They are all seven kilometers, and everyone is a brother project. Just borrow something. This is not a big problem.

The mech is performing its own mission underwater, but it can't be said about what mission it is. It's just going around underwater to test the sealing system.

The possibility of problems is basically zero.

So the people in the base are calm.

The mecha stayed in the water for more than 20 minutes. During this period, the dark clouds in the sky dispersed and the weather finally cleared.

The people on the sea in the distance finally have a good view.

"It's a pity that the mecha has gone to sea!"

Chow Tai Fook and his roommate were holding binoculars in their hands, and they couldn't see the crimson storm under the water. The waters of Danshan Islands were not clean enough.

So they still watched the official shots in the live broadcast room. The originally yellow sea in Danshan waters became more turbid after the crimson storm hit the sea.

"The sand below is so big, will the mecha enter the sand? The parts inside the mecha should be quite fine, right?"

"The mecha can be launched directly into the water. Tell me you can still get in the sand?"

"Don't be afraid, everyone. This is only the latest fishing robot developed by our country. Because our country has a lot of people and eats a lot of fish, it is reasonable to need a fishing robot of this size?"

"Yes, yes, it and the three frigates on the water belong to the same fishing team."

The people in the live broadcast room looked at the muddy sea, and they were all playing tricks.

However, some people suddenly thought of someone when they looked at the mud and sand rising under the water.

"It's not environmentally friendly, howdareyou!"

"Watching this scene in the dark, the young girl actually did this!"

"Haha, tomorrow I will wait for her news!"

...

The three brothers under the sea have been paying attention to the state of the mecha. Seeing that the time is almost up, they immediately walked up from the sea.

Wow~

The sea surface was gradually calming, and the sea surface suddenly had wind and waves, the shadow of the mecha gradually appeared on the water surface, and the behemoth was about to emerge from the bottom of the water!

"Dear viewers, Crimson Storm should have completed its underwater mission and will soon return to the surface!"

On the helicopter, the reporter who had been watching the sea immediately became excited, almost roaring.

The photographer immediately aimed the lens at the surface of the sea, and the contours of the mecha under water gradually became apparent.

The audience in front of the TV and the live studio were all excited.

Sure enough, at the next moment.

The huge mecha walked on the rising bottom of the sea, and the upper body came out of the water.

Wow!

The stream of water brought up, waterfalls generally flow down from various parts of the upper body of the mecha.

Crimson Storm made a head-shaking motion and shook off all the water droplets remaining near the observation window.

However, it was this seemingly normal movement that was shocked in the eyes of a group of interested people.

This is too sensitive!

This action is very common in the eyes of normal people, but you must know that the person who made this action was not a human, but a 76-meter-high mecha!

The three frigates on the sea in the distance saw the mecha return to the surface, and soon came over and continued to lead the way ahead.

The sun penetrates the clouds, and the way home is ahead!

On the sea, the tourists on the cruise ship finally clearly saw the true face of the crimson storm in the sun. Even if it just emerged from the muddy seabed, there was no filth on its surface.

"It's so beautiful! This trip is still not in vain, God still loves me!"

Chow Tai Fook's telescope was in front of his eyes, wishing to hang his eyes on the mecha.

And his roommates, other tourists on the boat, and even the entire sea area, everyone, whether they are tourists or cruise ship staff, all have binoculars in their hands, excitedly watching the red storm return sailing, their silhouettes are moving more and more. far……

In the general control room, after celebrating the smooth experiment, everyone immediately became busy, communication has been restored, and the underwater operation data of the mecha was transmitted back.

Everyone is staring at their computer, not letting go of a little detail...
