Short-wave is easy to attenuate in water, and if you want to send a signal on the seabed, you must use ultra-long-wave or extremely long-wave communication, which is the direction of signal transformation of seabed seismograph.

As for the problem of seabed water pressure, the seismograph must be structurally modified to adapt to the strong water pressure on the seabed, otherwise whether the instrument can work normally under such a terrible water pressure is a big problem.

Mo Nu helped to optimize the structure of the seismograph, and Chen Mo also entered the science and technology library and obtained a set of extremely long-wave communication technology. Extremely long-wave communication technology, which is one-way, can only transmit, can not receive signals, and is generally used in the communication of submarines.

But with the current conditions, it is already remarkable to be able to send a signal hundreds or even thousands of meters under the sea. It is also necessary to install a buoy-style antenna outside the seismograph.

With the help of artificial intelligence and the Science Library, as well as the full support of the marching ant company, the transformation of the seismograph went smoothly.

Now that the seismograph has come out, Chen Mo has poured all his energy into the manufacture of the seismograph. In order to be able to produce all the required seismographs before the Academy of Sciences' ocean-going scientific expedition.

The scientific expedition team on land cooperated with Binhai University to enter Tibetan areas with professors and students. Everything is in full swing.

The turmoil of the paper has passed, there has been no big news for a long time, and now no one pays attention to the marching ant company, and the eyes of the media have turned to other places. In addition, the actions of the marching ant company are kept secret, so outsiders don't know what big moves the marching ant company has.

At the Binhai Pier, as the last huge box was loaded onto the ship, Chen Mo let out a sigh. For two months, he had been preparing for the day all the time, and now it had finally arrived.

"There is a tutorial video of seismograph installation here, it's very simple, you hand it over to Mr. Wu Zhen by hand." Chen Mo took out a USB flash drive and handed it to Li Chengzhi.

Li Chengzhi took the USB flash drive and put it away, and glanced at Chen Mo deeply. Chen Mo's application for this project this time was surprisingly smooth, perhaps because he wanted to see if Chen Mo could create a miracle.

He was not worried that these instruments would be fished away by other countries, he asked Chen Mo this question, and Chen Mo also told him that he had been prepared.

Once it starts, if you want to fish it up again, you must command it to stop running, otherwise it will start the self-destruct function.

When such a large device is put in there and sends a signal, once the existence of the signal is discovered by other countries, it will definitely find a way to catch it.

There's a lot of technology in there.

In order to fish up without leakage of technology and without terminating operation, the seismograph will open up on the seabed and self-destruct with the help of strong water pressure.

The seismograph has been transformed into a semi-intelligent machine by Chen Mo, if he is given a little more time, he doesn't mind transforming the seismometer into a robot that can move on its own, and it will be difficult to fish it up when the time comes.

After saying goodbye to Chen Mo, Li Chengzhi boarded the ship and left, sending the equipment to the ship of the scientific expedition team.

"Is the instrument really okay?" On the way back, Xiao Yu looked at Chen Mo on the side.

"Don't worry, even if they throw the instrument directly into the sea, after it sinks to the seabed, it will start on its own, it's just a matter of location. Mr. Wu is an expert in earthquakes and knows which location is the most suitable for installation, so it is better and there will be no big problem. Chen Mo said confidently.

"That's good, now it's over." Xiao Yu said: "You have been busy for two months, take a two-day rest." ”

"The seismographs sent into Tibet should have arrived, and they should have done the installation, and now the work has come to an end and is ready to enter the next stage. These two days will be with you, relax and relax, and you can go wherever you want. ”

"I want to go to the movies." Xiao Yu smiled: "You haven't watched a movie with me for a long time." ”

"That's all you need." Chen Mo was amused by Xiao Yu, only in front of him, Xiao Yu would show the side of a little woman.

"That's what I'm good at." Xiao Yu said confidently.

Tibetan.

Zhang Songlin touched the two-meter-high cylindrical instrument and looked amazed.

He is a professor at the Faculty of Geographical Sciences of Coastal University and has a research interest in geology. This time, the marching ant company cooperated with Binhai University, and it happened that he had a geological expedition to come to Tibet, so he was sent over.

This time, his inspection projects were also sponsored by the marching ant company.

Their mission this time was to install 10 seismographs in 10 locations. The marching ant company has negotiated with the Tibetan district government on the formalities, and there is no problem.

He's a professor of geology, and the geology of this place, he knows very well, is above the fault.

The sudden movement of crustal faults along faults is the main reason for earthquakes, especially near the junction of the plates, where the crust is active, and this area is one of the most earthquake-dense places in China.

Scientists have been studying these faults for a long time, and as long as the fault mechanism is studied deeply, earthquakes can be accurately predicted, and now Marching Ants is doing just that.

I think that at the beginning, when Chen Mo first published that paper, he didn't believe it, but he didn't expect that he would come to help the marching ant company now.

"Professor Zhang, the borehole has been drilled." Just as Zhang Songlin was lamenting the achievements of the marching ant company, a worker wearing a hard hat walked over and interrupted his thoughts.

Zhang Songlin reacted and patted the seismograph at hand: "Move the instrument above the borehole and prepare for installation." ”

This is a confidential project, he doesn't dare to say that this is the seismograph of the marching ant company, these things are only known to those who should know.

As soon as Zhang Songlin's words fell, several workers carried seismographs and walked towards the top of the hole.

"Take a clockwise rotation so that the three holes below are aligned." As soon as several workers lifted the instrument to the hole, a staff member in charge of looking at the position spoke.

After two minutes, the holes are aligned.

After connecting the circuit, Zhang Songlin opened the slot of the instrument, followed the tutorial he had seen, and pressed the start button.

Airplanes!

The sound of machinery running, the three closed holes under the seismograph suddenly opened, and three probes slowly stretched out into the underground boreholes.

As soon as the probe stopped, Zhang Songlin opened the top of the instrument, and the geomagnetic field detector composed of coils rose and was exposed to the air. The appearance of the seismograph is not flattering, but Zhang Songlin still follows the steps to debug.

After the debugging was completed, Zhang Songlin took out the computer and began to receive information from the seismograph.

In another location, Luo Changhua is also doing the same installation work. They have to install ten machines, which are installed in two ways, and the work efficiency is higher.

The installation of seismographs in Tibetan areas is proceeding steadily.

maritime

After the six large boxes were sent to the research ship, a group of experts immediately surrounded the boxes, led by Wu Zhen.

Many people have curiosity on their faces, what exactly is the thing they asked them to express this time.

Their first destination for this scientific expedition was marine biology, marine chemistry, marine physics, marine geology and other projects, and the first destination was the Mariana Trench.

At that time, the submersible needs to be launched to collect samples, and the equipment of the marching ant company will also be placed in a suitable position on the seabed. Chen Mo said the approximate location, and the specific situation was to be judged by Wu Zhen, a geological expert.

"Let's open all the boxes." Wu Zhen, who took the lead, said.

As soon as his words fell, several staff members immediately walked over and unlocked the box. A specially revised version of the undersea seismograph was displayed in front of everyone.
