Movie black technology

The crimson storm slowly disappeared on the water, and people on the sea completely lost their sight.

Originally, China Central Television arranged to follow the filming under the sea, but now it is raining and the sea conditions are unstable, so it has to be temporarily canceled for safety reasons.

After entering the water, the crimson storm quickly reached the end of the route.

"General control room, we have arrived at the designated mission point..." He Chuan habitually turned on the radio report.

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

"We just need to make sure that the instrument is not damaged, record the data of this dive, and send it back to the main control room after landing." At the critical moment, the elder brother He Xin said.

"En!" The two younger brothers responded in unison. Chen Shen also told them about this matter, but he suddenly forgot.

Inside the main control room.

Chen Shen looked at the live broadcast, the scene of the crimson storm diving into the water, almost at the same time the mecha dived into the water, all the data about the mecha on all the computers in the main control room stopped transmitting.

But the crowd did not panic.

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

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

At this time, 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 communication at a depth of 7,000 meters underwater. In fact, the technology hidden in these short shots is already quite terrifying.

You must know that except for the extremely long waves, the radio wave communications commonly used by people at sea basically cannot penetrate a distance of 30 meters underwater, let alone 7 kilometers underwater.

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

However, this method also has a lot of troubles. Sound waves can only travel more than 1,000 meters per second, slow propagation speed and long delay, large noise in water, and large signal interference. Many problems have always been difficult problems in this field.

If you want to rely on underwater acoustic communication to achieve the effects in the movie, the transmission delay of sound waves alone cannot solve the problem.

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

In the technical data of Crimson Storm, there is only the receiver and transmitter technology of underwater communication signals, and the technology of the entire underwater communication system is not directly given.

Because the underwater communication system is an independent and huge system, it does not belong to the mecha technology, and its only direct connection with the mecha is the signal receiver and transmitter installed on the mecha.

And the system will not give something that has nothing to do with the project technology.

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 could not help him restore the entire system immediately, so in the initial technical outline, he deleted the underwater communication system of the mecha, and added it later.

There is no rush for this.

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

They are all at the 7,000-meter level, and everyone is a brother project, so it’s just a matter of borrowing something, which is not a big problem.

The mecha is performing its own mission underwater, but it's not really a mission, it's just going around underwater to test the sealing system.

The chances of something going wrong are basically zero.

So the people in the base are very 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 gradually cleared up.

People on the sea in the distance finally had a good view.

"It's a pity that the mech went into the sea!"

Zhou Dafu and his roommate held binoculars in their hands, and they couldn't see the crimson storm under the water. The waters of the Danshan Islands were not so clean.

So they were still watching the official footage in the live broadcast room. The originally yellowish sea surface in the Danshan sea area became obviously more turbid after the crimson storm entered the sea.

"The sand below here is so big. Will the mecha get in the sand? The parts inside the mecha should be quite fine, right?"

"The mecha can go directly into the water, and you tell me that the sand can still go in?"

"Don't be afraid, everyone. This is just 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 such a large fishing robot, right?"

"That's right, it belongs to the same fishing team as the three frigates on the water."

The people in the live broadcast room looked at the turbid sea, all playing tricks.

However, some people looked at the silt rising from the bottom of the water and suddenly thought of a person.

"It's too environmentally friendly, how dare you!"

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

"Haha, I'll wait for her news tomorrow!"

...

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

Wow~

The sea gradually calmed down and suddenly there was a storm again, the shadow of the mecha gradually appeared on the water surface, and the huge monster was about to come out of the bottom of the water!

"Friends in the audience, now the crimson storm should have completed its mission at the bottom of the water and is about to return to the surface!"

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

The photographer pointed the lens at the sea surface for the first time, and the outline of the mecha under the water gradually became clear.

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

Sure enough, at the next moment.

The huge mecha walked on the gradually rising seabed, with its upper body sticking out of the water.

Crash!

The streams of water brought up by the waterfall generally flow down from various parts of the mech's upper body.

Crimson Storm made a movement of shaking its head, shaking off all the remaining water droplets near the observation window.

However, it was this seemingly normal action, but in the eyes of all interested people, they were shocked.

This is too sensitive!

This action is very common in the eyes of normal people, but you must know that the person making this action is not a human being, but a 76-meter-high mech!

I don't even know how heavy that head is!

The three frigates on the distant sea saw the mech returning to the water surface, and soon drove over again, continuing to lead the way.

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

On the surface of the sea, the tourists on the cruise ship finally saw the true face of the crimson storm clearly under the sunlight. Even if it had just come out of the muddy seabed, its surface could not be seen to be dirty at all.

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

Chow Tai Fook's binoculars were right in front of his eyes, wishing he could hang all his eyes on the mech.

And his roommates, other tourists on the ship, and even the entire sea area, whether tourists or cruise ship staff, all of them held binoculars in their hands, watching the crimson storm return with excitement, and the figures were getting closer and closer. Far……

In the main control room, after celebrating the success of the experiment, everyone got busy immediately. The communication has been restored, and the operation data of the mecha underwater has been transmitted back.

Everyone is staring at their computer, not letting go of any details on it...
