Short waves are easily attenuated in water. If you want to send signals on the seabed, you must use ultra-long wave or extremely long wave communication. This is the direction of signal transformation for seabed seismometers.
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 terrifying water pressure is a big problem.
Mo Nu helped with the structural optimization of the seismometer, 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 is one-way and can only transmit but cannot receive signals. It is generally used in submarine communications.
But with the current conditions, it is already remarkable to be able to send signals hundreds of meters or even thousands of meters under the sea. It is also necessary to install a buoy-type antenna outside the seismometer.
With the help of the Artificial Intelligence and Science and Technology Library, as well as the full support of the Marching Ant Company, the renovation of the seismograph went smoothly.
Now that the seismograph has come out, Chen Mo has devoted all his energy to the manufacture of the seismometer. In order to be able to produce all the required seismographs before the Academy of Sciences' oceanographic expedition.
The scientific expedition team on land cooperates with Binhai University to jointly enter the snow area with professors and students. Everything is going on in full swing.
The controversy over the paper has passed, and there has been no big news for a long time. Now no one pays attention to Army Ant Company, and the media's attention has turned to other places. In addition, the actions of the Marching Ant Company are kept secret, so outsiders have no idea what big actions the Marching Ant Company has.
At the Binhai Pier, as the last huge box was moved onto the ship, Chen Mo let out a breath. He had been preparing for this day for two months, and now it was finally here.
"Here is a tutorial video on how to install a seismometer. It's very simple. Just hand it over to Mr. Wu Zhen." 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, then took a deep look at Chen Mo. Chen Mo's application for this project went surprisingly smoothly this time. Perhaps the higher-ups wanted to see if Chen Mo could create a miracle.
He was not worried that these instruments would be taken away by other countries. He asked Chen Mo about this question, and Chen Mo also told him that he had been prepared for it.
Once it starts, if you want to pick it up again, you must command to stop running, otherwise it will activate the self-destruct function.
When such a large device is placed there, when it sends a signal, once other countries discover the existence of the signal, they will definitely find a way to retrieve it.
There are a lot of coveted technologies here.
In order to prevent the technology from leaking and to retrieve it without terminating its operation, the seismometer will open 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 was given a little more time, he would not mind transforming the seismograph into a robot that could move on its own. It would be difficult to pick it up by then.
After saying goodbye to Chen Mo, Li Chengzhi boarded the ship and left, sending the equipment to the scientific expedition team's ship.
"Is there really nothing wrong with the instrument?" On the way back, Xiao Yu looked at Chen Mo who was standing aside.
"Don't worry, even if they throw the instrument directly into the sea, it will start by itself after it sinks to the seabed. It's just a matter of location. Mr. Wu is an expert in earthquakes and knows which location is most suitable for installation. This is better, no There will be too many problems." Chen Mo said confidently.
"That's good, now it's over." Xiaoyu said, "You've been busy for two months, take two days off."
"The seismometer sent to the snow area should have arrived. They should be able to do the installation. Now the work has come to an end and we are ready to enter the next stage. I will accompany you for these two days, relax and go wherever you want. "
"I want to go to the movies." Xiaoyu said with a smile, "It's been a long time since you went to the movies with me."
"That's all you have." Chen Mo was amused by Xiao Yu. Only in front of him would Xiao Yu show his feminine side.
"That's all I have to offer." Xiaoyu said confidently.
Snow area.
Zhang Songlin touched the two-meter-high cylindrical instrument with a look of wonder on his face.
He is a professor at the School of Geographical Sciences of Binhai University and conducts research on geology. This time, Army Ant Company cooperated with Binhai University. It happened that he had a geological survey to come to the snow area, so he was sent over.
This time, his inspection project was also sponsored by the Army Ant Company.
Their mission this time was to install ten seismometers at ten locations. Regarding the formalities, Marching Ant Company has negotiated with the snow area government and there is no problem.
He is a professor of geology, and he knows the geology of this area very well, above the fault.
The sudden movement of crustal blocks along faults is the main cause of earthquakes. Especially near the junction of plates, the crust is active. This area is one of the most earthquake-intensive places in China.
Scientists have been studying these faults. As long as the fault mechanism is studied in depth, earthquakes can be accurately predicted. Now the Army Ant Company is doing this.
Back then, when Chen Mo first published that paper, he didn't believe it, but he didn't expect to come to help the Marching Ant Company now.
"Professor Zhang, the drilling has been done." When Zhang Songlin was lamenting the achievements of the Army Ant Company, a worker wearing a safety helmet came over and interrupted his thoughts.
Zhang Songlin reacted and patted the seismograph at hand: "Transport the instrument to the top of the borehole and prepare for installation."
This was a confidential project. He didn't dare to say that it was a seismometer from the Army Ant Company. Only those who should know knew about these things.
As soon as Zhang Songlin finished speaking, several workers carried the seismograph and walked up to the cavity.
"Rotate one step clockwise to align the three holes below." As soon as several workers lifted the instrument to the holes, a staff member responsible for checking the position spoke.
After two minutes, align the holes.
After connecting the circuit, Zhang Songlin opened the slot of the instrument and pressed the start button according to the tutorial he had read.
Buzz!
The sound of mechanical operation sounded, and the three closed holes under the seismograph suddenly opened, and the three probes slowly stretched out and entered the underground borehole.
As soon as the probe stopped, Zhang Songlin opened the top of the instrument, and the geomagnetic field detectors composed of coils rose up and were exposed to the air. I can’t compliment the appearance of the seismograph, but Zhang Songlin still followed the steps to debug it.
After debugging, Zhang Songlin took out his computer and began to receive information from the seismometer.
At another location, Luo Changhua is also doing the same installation work. They want to install ten machines, which will be installed in two lines to make the work more efficient.
The installation of seismometers in snowy areas is progressing steadily.
maritime,
After the six large boxes were sent to the scientific research ship, a group of experts immediately surrounded the boxes, led by Wu Zhen.
Many people had curiosity on their faces as to what they were asked to express this time.
Their scientific expedition included marine biology, marine chemistry, marine physics, marine geology and other projects. The first destination was the Mariana Trench.
When the time comes, the submersible will need to be launched into the water to collect samples, and the equipment of the Army Ant Company will also be placed in a suitable location on the seabed. Chen Mo gave an approximate location, but Wu Zhen, a geological expert, had to judge the specific location.
"Open all the boxes." Wu Zhen, the leader, said.
As soon as he finished speaking, several staff members immediately walked over and opened the lock of the box. A specially modified version of the submarine seismograph was displayed in front of everyone.
Cultivation is completed.
