Chapter 1237: Remote control and communication delay

As the temperature further increased, Prandall soon entered the hottest summer month of the year. The workers in the factory received high-temperature allowances and laughed. The school also began the final exams immediately. It's summer vacation, and the smiles on the students' faces are getting brighter and brighter. They will soon have a very pleasant vacation.
At this time, various research projects at the Magic Energy Engineering Research Institute are in full swing-or in other words, there is always busy here, and there is no rest.
Since the computer of the prehistoric civilization was excavated from Alar's ruins, Eve at the Academy has been continuously copying, learning, and analyzing the data in the computer. After so long, I finally got a lot from it Useful information.
Among them, various materials on the prehistoric civilization's life form and scientific and technological form provided a lot of reference materials for the researchers of the Magic Energy Engineering Research Institute, which inspired them, and a variety of new ideas and new products appeared continuously. In the list, they were restored with amazing ideas.
Although the processing accuracy of Prendall is not as high as that of prehistoric civilization, the current civilization has a powerful power that prehistoric civilization does not have-magic.
Convenient magic power can work wonders in many places. Many products that originally required complex craftsmanship and advanced scientific and technological theories can be easily solved after using the power of magic.
For example, ultra-high magnification telescopes were originally developed based on very powerful lens processing technology, optical analysis technology, information data conversion technology, etc., but after obtaining the corresponding information, those guys in the institute directly Combining hawk-eye technique and existing telescope technology, an ultra-high magnification telescope comparable to prehistoric civilization has been developed.
Another example is network technology. The Internet of the prehistoric civilization, like the earth, started from a fixed-line network and then gradually developed into a wireless network covering the entire world. But now? Researchers directly use the magic wave theory proposed by Tang En as a theoretical basis. The starting point is to cover the entire Prandall wireless network-this network is readily available, as long as they use certain technology as a support and use it. .
Or aircraft technology. From those materials, they found that the prehistoric civilization ’s aircraft technology has developed to use anti-gravity (dwarf gravity well) to control the hovering of the aircraft, adjust mathematical parameters to achieve forward and backward functions, etc. Of course, Prandall could not directly restore the technology of gravity wells, and even Clotto might not have the ability to fully recover the technology of gravity wells.
But now there is magic. Arcane has a spell that can control gravity to achieve a similar effect. In addition to floating stones, a wonderful product that later appeared, it is too easy to fly into the sky.
With the development of technology and technology, if the physical structure and anti-gravity principle of floating stones can be found in the future, this generation of civilization can even try to simulate the environment where floating stones are born and produce floating stones.
These are all places where modern modern civilization is superior to prehistoric civilizations.
Although it is not conscience to say so, Tang En still wants to say that the ancestors of the gnome and the goblin did a good deed-if it were not for the big bang ten thousand years ago, the world would not present this kind of high energy The state of the set will not give birth to so many wonderful species and materials, nor will there be such a magical power of magic.
After this period of analysis work, the Magic Energy Engineering Research Institute has recently shifted its focus to how to maintain stable remote communication and control. The corresponding instruction set has been developed and loaded into the artificial soul computer. Now Preparing for actual usability testing.
In the project department of computer remote communication control technology, Tang En and others were surrounded in front of an artificial soul computer, staring at the pictures in front of them, all very nervous.
Croto, sitting in front of the computer, stared at the screen without blinking: "The system connection is complete ... the remote control system is online ... the system has been successfully started, and the remote monitoring screen is now being broadcast!"
As soon as he finished speaking, a picture thousands of miles away appeared on the previous screen-another remote control computer had been sent one step ahead of the other end of Prendall, the heart of the dragon above the East China Sea, at the moment Waiting for the communication was the Dragon King Saschagalte. When he saw the screen in the research room suddenly appearing on the screen that was empty, he was surprised: "I really started it!"
This artificial soul quantum computer did not start at first, but a passive receiving module was added to the starting module. After receiving a matching signal, this module would trigger a simple mechanical device to turn on the computer's energy to turn on. Computer and then automatically enter the remote control system.
At the same time, this system is no longer a general-purpose system, but a special system specially developed for remote control.
Sasha Glott's voice came clear and incomparable. There was a cheer in the laboratory, and Croto took a deep breath: "The communication test within 10,000 kilometers is complete! The next step is the test of the remote control command. -Spark! Rotate the camera 180 degrees! "
The Spark in the distance was delayed by several tens of milliseconds and then executed the instructions of Croto-the research room cheered again and succeeded again!
Only Tang En frowned--this was less than ten thousand kilometers, and there was a slight delay? In this respect, the magic network does not seem to be comparable to the wireless electromagnetic network ...
Although wireless electromagnetic wave networks will also experience very serious delays in interstellar communications, at least in the open environment inside the planet, there will be no attenuation and delay at all, and the speed of wireless electromagnetic waves is the same as the speed of light. Although the speed of light in this world is not known How much is not conditional to test, but there will not be too much difference, right? A speed of 300,000 kilometers per second to form a communication network inside the planet is absolutely sufficient.
"My friend, you don't seem to be satisfied?"
Cloto noticed Don's expression, and was suddenly surprised. The successful implementation of this technology meant that they could soon realize the next step. Once that function was implemented, the entire Prandall would be completely Change, and this historic change will be born from his hands, just thinking about the excitement that he ca n’t sleep!
Tang En shook his head: "At this stage, it is very satisfactory, but if you stand in the perspective of long-term development, it will not work."
"why?"
"Because of the delay."
"delay?"
Croto's face was violent. "What's that?"
Delay is still a very new concept for the Prandall natives, and they don't even know how important this thing is.
For Tang En, who claims to be a "pro player", the delay is second only to having a fantastic computer!
"It's the time it takes for a target to receive an instruction and execute it."
Tang En briefly explained the concept of delay, but Croto still couldn't understand it. He re-issued several instructions, and felt that the instructions were perfectly executed!
"That's because you haven't noticed. In fact, the Spark has paused for a moment while executing the command. The further this pause is, the more obvious it is."
Tang En pointed at the picture and said, "In fact, the picture we are seeing now has some delay."
"I see, but what's the matter?"
Croto still couldn't understand.
"For example, if we add a remote control module to an airship and we stand on the air tower to remotely control the airship, do you know how much a one-second error can have? A second later can cause Great distance deviation! "
Tang En made a comparison with his hand: "For another example, if we add a remote control module to a long-range missile, we have to hit the target from a very long distance, then at the speed of the missile, your command is half a second late. When the clock is executed, the distance from the locked target may be very different ... the longer the distance, the higher the delay, the faster the speed, and the greater the deviation. "
After Tang En gave these two examples, Croto understood the concept and importance of "delay", and then he scratched his head: "So how do we solve this problem?"
"Two ways."
"First, change to a faster information transmission medium. Now we use magic waves. If we change to electromagnetic waves, or light, or more powerful quantum, the speed will be faster."
"The second is to use existing methods to increase the speed of existing information transmission."
Tang En smiled bitterly. The first method now lacks the corresponding theoretical and technical support, so this method is not realistic at all, so there is actually only one method.
"Speed ​​up ... to strengthen the magic wave of the initial launch?"
"It's useless. The amount of energy contained in the initial wave will not affect the propagation speed, but only the distance, propagation range and signal strength of the first transition from the magic node."
"that……"
After Tang En groaned for a moment, an idea came to mind, and she listened to Yustisa's words, "I have an idea."
Angus exclaimed, "I have a way!"
The two looked at each other and both froze.
Yustis smiled: "You say first."
Angus nodded and said, "My approach is to add a space module to both the transmitting device and the receiving device, that is, to give up the non-directional wide area broadcast method, directly use directional broadcasting, and use the space module to open the miniature space tunnel. , Let the signal pass and then close, so you can shorten the transmission and reception distance in disguise, how fast the space tunnel is opened and closed, and how low the delay will be. We need to solve the technical problem of only the space module. But this The material and technical costs of the method are relatively high. "
