Chapter 1237 Remote Control and Communication Delay

As the temperature rises further, Purandhar soon enters the hottest month of summer in the year. The workers in the factory received high temperature allowances and smiled from ear to ear. The school also started final exams soon. Summer vacation is coming, and the smiles on the students' faces are getting brighter and brighter. They will soon have a very happy vacation.

At this time, various research projects at the Magic Energy Engineering Research Institute are also in full swing - or in other words, this place is always busy and never rests.

Ever since the computer of the prehistoric civilization was unearthed in the Alar ruins, Eve at the institute has been continuing to copy, study and analyze the data in the computer. After going on for such a long time, she finally gained a lot from it. Useful information.

The various information on the life forms and technological forms of prehistoric civilizations provided a large number of reference materials for the researchers of the Magic Energy Engineering Research Institute, inspiring their inspiration. Various new ideas and new products continued to appear. In the list, they restored it with amazing ideas.

Although the current processing accuracy of Purandar does not reach the level of prehistoric civilization, the current civilization has a powerful power that prehistoric civilization did 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 utilizing the power of magic.

For example, ultra-high magnification telescopes originally required very powerful lens processing technology, optical analysis technology, information data conversion technology, etc. as a basis. However, after obtaining the corresponding data, the guys at the institute directly Combining eagle eye technology with existing telescope technology, an ultra-high-magnification telescope comparable to that of prehistoric civilizations was developed.

Another example is network technology. The Internet in prehistoric civilizations was the same as on earth. It started as a fixed-line network and then gradually developed into a wireless network covering the entire world. But what about now? The researchers directly used the magic wave theory proposed by Tang En as the theoretical basis. The starting point was the wireless network covering the entire Purandal - this network was ready, they only needed to use certain technologies as support to make use of it. .

Or maybe it's aircraft technology. From those materials, they found that the aircraft technology of prehistoric civilizations has developed to the point where anti-gravity (dwarf gravity wells) are used to control aircraft hovering, and mathematical parameters can be adjusted to achieve forward and backward functions. Now Of course, Purandar cannot directly restore the technology of the gravity well. Even Clotto may not have the ability to completely restore the technology of the gravity well.

But now that there is magic, there is a spell in the arcane that can control gravity that can achieve similar effects. Coupled with the floating stone, a wonderful product that only appeared later, 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 discovered in the future, this generation of civilization can even try to simulate the environment where floating stones were born and produce floating stones.

These are the places where modern civilization in Purandar is superior to prehistoric civilization.

Although it is unconscionable to say this, Tang En still wants to say that the ancestors of the dwarfs and goblins did a good thing - if it were not for the big explosion ten thousand years ago, the world would not be as rich in energy as it is now. In a state of concentration, so many wonderful species and materials would not be born, nor would such magical power as magic appear.

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 installed into the artificial soul computer. Now Preparing for actual usability testing.

In the computer remote communication control technology project department, Tang En and others were gathered in front of an artificial soul computer, staring at the picture in front of them, all very nervous.

Clotto, who was sitting in front of the computer, stared at the screen without blinking: "The system connection has been completed... the remote control system has been online... the system has started successfully, and now the remote monitoring screen will be broadcast!"

As soon as he finished speaking, a scene thousands of miles away appeared on the screen in front of him - another remote control computer had been sent to the other end of Purandal in advance, to the Heart of the Dragon above the East China Sea. The person waiting for the communication was Dragon King Sasha Grot. When he saw the scene in the research room suddenly appear on the originally empty screen, he was shocked: "It really started by itself!"

This artificial soul quantum computer did not start up at the beginning. It just added a module to the startup module to passively receive startup instructions. After receiving the matching signal, this module will trigger a simple mechanical device to turn on the energy of the computer. computer and then automatically enter the remote control system.

At the same time, this system is no longer a universal system, but a special system developed specifically to accept remote control.

Sasha Grot's voice came over clearly, and cheers rang out in the research room. Clotto took a deep breath: "The communication test within 10,000 kilometers is completed! The next step is the test of remote control commands. ——Spark! Turn the camera 180 degrees!"

The Starfire in the distance carried out Cloteau's instructions after a slight delay of tens of milliseconds - the research room cheered again, another success!

Only Tang En frowned - it was less than 10,000 kilometers and there was already a slight delay? In this regard, the magic network seems to be inferior to the wireless electromagnetic wave network...

Although radio electromagnetic wave networks will also experience very serious delays in interstellar communications, at least there will be no attenuation and delays in the open environment inside the planet, and the speed of radio electromagnetic waves is the same as the speed of light, although the specific speed of light in this world is not known. I don't have the conditions to test it, but if there is a difference, it won't be too big, right? A speed of 300,000 kilometers per second is absolutely enough to form a communication network within the planet.

"My friend, you don't seem satisfied?"

Clotto noticed Tang En's expression and was immediately surprised. The successful implementation of this technology means that they will soon be able to realize their next idea. Once that function is realized, the entire Purandar will be completely destroyed. Change, and this historic change will be born from his hands. Just thinking about it makes him so excited that he can't sleep at night!

Tang En shook his head: "At this stage, I am very satisfied, but from the perspective of long-term development, it is not feasible."

"Why?"

"Because of the delay."

"Delay?"

Clotto was confused: "What is that?"

For the locals of Purandhar, delay is still a very new concept, and they don’t even know how important it is.

For Tang En, who calls himself a "professional gamer", latency is second only to having a fantastic computer!

"It is the time it takes for the target to receive instructions and execute them."

Tang En briefly explained the concept of delay, but Clotto still couldn't understand it. He issued a few new instructions and felt that the instructions were executed perfectly!

"That's because you didn't notice that the Starfire actually paused for a moment when executing the order. The farther away the pause is, the more obvious it is."

Tang En pointed at the screen and said, "Actually, the screen we see now is already somewhat delayed."

"I know, but what's the point?"

Cloteau still couldn't understand.

"For example, if we add a remote control module to the airship and we stand on the aviation tower to remotely control the airship, do you know how huge an impact one second of error can have? Even one second of delay may cause Huge distance deviation!”

Tang En gestured with his hands: "For another example, if we add a remote control module to a long-range missile, and we have to hit the target from an extremely long distance, then at the speed of the missile, your command will be half a second late. When the clock is executed, the distance to the locked target may be vastly different...the farther the distance, the higher the delay, the faster the speed, and the greater the deviation.”

After Tang En cited these two examples, Clotto finally understood the concept and importance of "delay", and then he scratched his head: "Then how should we solve this problem?"

"Two ways."

"The first one is to change to a faster information propagation medium. Now we use magic wave. If it is replaced by electromagnetic waves, or light, or more powerful quantum, the speed will be even faster."

"The second is to use existing means to find ways to improve the existing information transmission speed again."

Tang En smiled bitterly. The first method currently lacks corresponding theoretical and technical support, so this method is not realistic at all, so there is actually only one method.

"Speed ​​it up...strengthen the initial wave of magic power?"

"It's useless. The amount of energy contained in the initial wave will not affect the propagation speed. It will only affect the distance, propagation range and signal strength of the initial jump from the magic node."

"That……"

After Tang En pondered for a moment, an idea appeared in his mind, and he heard Justina say: "I have an idea."

Angus shouted: "I have a solution!"

The two looked at each other and were stunned for a moment.

Justina smiled and said, "You say it first."

Angus nodded and said: "My solution is to add space modules to both the transmitting device and the receiving device. That is to say, abandon the non-directional wide-area broadcast method, directly use directional broadcast, and use the space module to open a micro-space tunnel , let the signal pass through and then turn it off, so that the distance between transmission and reception can be shortened in disguise. The faster the space tunnel is opened and closed, the lower the delay will be. We need to solve the technical problem of the space module. But this The material and technology costs of this method are relatively high.”
