Chapter 264: Communication test

Chen Xin naturally knew nothing about what happened to Qin Lan, and at this moment he was still on his way home.
"Mr. Chen, why should we go from the three towns? If you go to Huanggang City, you can save a lot of time." Han Ping studied the map he was working on, and some did not understand Chen Xin's choice.
Although there are no other refuges and supply points on the way back from Anhui Province along the original road where Chen Xin came before, so that the material consumption is a bit high and must be replenished, but Huanggang City is an important city in Hubei Province. , No matter how there are refuges, you can supply supplies.
Therefore, Han Ping did not understand why Chen Xin had to go around the three towns and travel a long way.
In response, Chen Xin just replied: "I had an appointment with someone when I came, and I have to go to Three Towns when I return."
Hearing what Chen Xin said, Han Ping didn't say much. He was just expressing his doubts and didn't want to interfere with Chen Xin's decision.
For Han Ping, he is Chen Xin's driver. It is his responsibility to ask questions, but it is Chen Xin who makes the decision. Since Chen Xin has made a decision, he only needs to implement it.
Unless the decision given by Chen Xin is too unthinkable, in Han Ping's view, all he needs to do is implement it.
Handing over the driving matter to Han Ping, Chen Xin turned and walked to the rear living cabin, planning to take a rest.
With the addition of the two brothers, Han Ping and Han Ze, the biggest benefit for Chen Xin is that he is a lot easier. Most of the things can be left to the two brothers, and he only needs to give orders.
The elder brother Han Ping is responsible for driving, and the younger brother Han Ze is responsible for acting as the co-pilot. At first, the two brothers were a bit jerky about the car, but after getting familiar with the driving style of this car, they were already able to do their job well. Chen Xin can safely leave all driving matters to them.
Back in the living cabin, Chen Xin saw his father standing in front of the planting box, seeming to want to water the vegetables inside, so he walked over to his father and asked, "Dad, what are you doing here? My mother. What?"
"Your mother is resting on it." Chen Xin's father pointed to the top of his head, and then looked at the planting box in front of him and asked Chen Xin, "Does this thing need to be watered every day for growing vegetables?"
"Well, you don't need to water every day. It has its own irrigation function. It will drip irrigation according to the soil moisture and crop growth to ensure the water needed for crop growth without overwatering." Chen Xin explained One sentence.
Hearing what Chen Xin said, Chen Xin's father couldn't help showing an expression of surprise: "Technology is so advanced now, you don't even need to water it yourself."
"Yes, the development of science and technology is still fast." Chen Xin also nodded in agreement, echoing his father's words.
When talking about this topic, Chen Xin's father didn't know what he thought of, and he suddenly asked Chen Xin: "Son, do you think mankind will perish?"
"No." Chen Xin gave the answer to his father's question without even thinking about it.
"But now there is no sunshine, nor can we farm the land. The weather outside is still so cold, how can human beings survive?" Chen Xin's father obviously had difficulty accepting Chen Xin's answer, or he wanted to get something from Chen Xin that could convince him. The reason, he still asked Chen Xin.
"The dust in the sky will disperse in a few years. Although the dust in the stratosphere may not settle down for hundreds or even thousands of years, but the dust in the troposphere will have almost settled in ten or eight years, and the sun will It was re-photographed on the ground." Chen Xin had also asked Zhang Chengguang and others related questions before. At this time, when his father asked, he naturally answered positively.
Before landing on the Blue Star, Zhang Chengguang and the others used the observation equipment of the space station to observe the Blue Star for more than half a year. According to their observations, the Blue Star was surrounded by a large amount of dust and debris formed by the impact of meteorites.
These materials set off by meteorite impacts are distributed throughout the atmosphere and the blue star's near-Earth orbit, from the lowest troposphere to the top outer dissipative layer, which is densely distributed. It is these dusts and debris that hide it. The sky prevents sunlight from reaching the ground.
Among them, debris with a relatively large volume and weight will fall to the ground first due to the influence of gravity, and burn out due to atmospheric friction.
The remaining dust will fall one after another according to its height in the atmosphere.
The dust in the troposphere at the bottom of the atmosphere will be the first to fall, and the dust in this layer is relatively dense. When the dust in this layer settles, the surface of the earth will transform from a dark environment to dim light. And the light intensity will gradually increase.
Although the dust in the higher atmosphere will be difficult to fall because the upper atmosphere is mostly translational, the light will still be restored to a human acceptable level within ten years.
Chen Xin explained to his father about sunlight, and then added:
Sunlight is not the most critical factor restricting mankind. Taking the technology currently mastered by mankind, even if there is no sunlight for ten years, it will cause a great Many people will die because of insufficient food and cold, but they have not yet destroyed humanity."
Hearing what Chen Xin said, his father was obviously relieved. The hardships he faced after the disaster was not difficult, but the absence of hope and the future was the most unbearable.
Chen Xin obviously understands this, so he said to his father: "The country is now beginning to rebuild after the disaster. The towns and villages underneath may not feel much, but big cities like the three towns are gradually recovering. Now. Maybe the current living conditions will be a bit tougher, but the future will definitely get better!"
"You kid don't need to comfort me. I have suffered more than your generation. It is not your turn to comfort me for this kind of thing." Chen Xin's father was a little embarrassed, but he still maintained his fatherhood. majesty.
While the father and son were still talking about this topic, Han Ze suddenly ran over from the cockpit and said to Chen Xin: "Mr. Chen, come and take a look. We received a signal from the three towns. , They seem to be testing some equipment."
"The three towns are testing the equipment? We are still a lot away from the three towns? Can we receive their signals now?" Chen Xin was shocked and went back to the cab with Han Ze.
Regarding Chen Xin’s question, Han Ze hurriedly introduced the situation:
I was debugging the radio station just now, and wanted to see if it could receive the signal. As a result, I received the communication from the three towns, but they did not send it to us. It should be a test that started a high-power signal source, but we just happened to be within the signal coverage."
Chen Xin nodded slightly. After understanding the situation, he sat directly in the passenger seat and said to the console: "The system, replay the signal just received."
"The signal is playing..." The electronic sound of the system sounded, and a segment of the signal was replayed.
"...Long...communication...in the test, third...test..." The signal does not seem to be very clear, but it can still be heard clearly.
Listening to the intermittent signals played by the system, Chen Xin understood what was going on.
Just like Han Ze said, this should be a test, and his car only received the signal when it was within the signal coverage.
Chen Xin didn't feel any strange about this. There are so many scientific research institutions in the three towns, and it is not strange to do communication tests.
As for the fact that your car is shrouded in the signal coverage area, this is no surprise. This means that the satellite signal cannot be received in this environment now, otherwise it would be strange if there is no signal.
"People are doing a communication test, so let's just leave it alone." Chen Xin confirmed what was going on, so he didn't care about it. He said to Han Ze and stood up to leave the cab.
At this time, however, a new signal was received on the console: "Thanks to...the Chen Xin...the adjustment...this set of...equipment finally...to achieve a long distance...the news."
Hearing this, the expression on Chen Xin's face couldn't help showing a look of interest. Is this matter related to him?
It sounds like it is related to the set of communication equipment that he adjusted for a while when he visited the three towns last time, so are they now testing the equipment they adjusted?
Chen Xin just thought about it a little bit and thought of what was going on, so he reached out and picked up the intercom on the console~EbookFREE.me~ With a little manipulation, the signal of his car was also connected to the other party's. In the communication channel, he pressed the call button and said, "I seem to hear someone mention my name. It seems that the equipment I adjusted last time worked well!"
"Mr. Chen Xin? Why are you on our channel?" The other party seemed very surprised that Chen Xin was able to access their communication channel, but he quickly reacted: "Mr. Chen Xin, are you back from Anhui Province? "
"Yes, I'm on my way back, and I should arrive in the three towns in two days." Chen Xin answered the other party's question and also said, "Are you testing the equipment? Then I won't disturb your work. Up."
"No, no, Mr. Chen Xin, if you can, we hope you can help us test the new equipment!" The other party obviously did not intend to let Chen Xin withdraw.
Researchers who have seen how Chen Xin modulates the device instantly will not let go of a powerful foreign aid such as Chen Xin, and Chen Xin is now just outside the three towns, with his help to test the signal stability of the device when the target is moving. A very important test can save them a lot of things by allowing Chen Xin to help.
"Okay, how can I help?" Chen Xin was not stingy, anyway, it was just a matter of effort, idle on the road and idle.
