Chapter 6: Confidence

Seeing the two nodded, Wu Hao changed another page of PPT and continued to preach: "And our technology is much more advanced than them.

I also have four major systems under this technology: real-time interactive remote control system, UAV data interconnection system, interconnection information processing system, and real-time attitude control system.

First of all, let's talk about the real-time interactive remote control system. This is well understood, that is, the remote control of the drone cluster, so that it can achieve or achieve the attitude and stereo we require.

On the surface, we are no different from the remote control technology on the market. In fact, this direct difference is still very big.

Our characteristics, we can grasp the data fed back by the drone in real time and flexibly control the drone. This control can be through procedures or direct human control. "

"But in this case, the amount of calculation will be very large, you need a special host for calculation control. And you have to take into account the time generated by the calculation and the delay in the transmission process on the flight control." Zou Xiaodong raised his own question.

Wu Hao nodded and laughed: "So, we need a data interconnection system and an information processing system to solve this problem.

The unmanned aerial vehicle control system on the market is actually a host sending information instructions to N unmanned aerial vehicles, that is, 1? N [connection symbol] mode, there is no information interaction between the unmanned aerial vehicles.

And our UAV data interconnection system technology can realize the information communication between the drone and the drone, and the interactive connection between the drone and the drone and the ground control host, thereby achieving 1 ? N? N way. "

As soon as his words were finished, Zou Xiaodong replied: "The design of the circuit and the connection of the circuit is a science, not just the connection. It is necessary to connect the N devices in an optimal way and make a reasonable connection.

The speed of information transmission of these devices will not be delayed or blocked because there are many cross-devices.

Connect N drones in an orderly and reasonable way, then the workload and difficulty will be very large. Then again, I don't know what the role of interconnecting the data of these drones is. "

The problem raised by Zou Xiaodong is actually a complex problem in the computer field, especially in large computers and servers.

Assuming there are 30 computers, how to connect these 30 computers? The simplest way is probably to connect them together.

But there will be problems. Computer 1 and computer 2 are connected smoothly with the least delay.

What about computers 1 and 30? If you want to interact with data, you must cross the middle 28 computers.

The best and most direct way is to add a root line to connect No. 1 with No. 30. Then there are Nos. 1 and 15, Nos. 15 and 30, and even Nos. 7 and 15. So in the end, this will result in a complex line network.

This is only 30 devices. Like some mainframe computers or servers, there are thousands or even tens of thousands of subsystems (sub-devices).

How to connect all these things may be one of the first difficult problems to be solved in the development of a large computer.

Wu Hao changed the page PPT again, and I saw that the title of this page read 'Interconnection Information Processing System'. At first, the two didn't care. When they saw the following description and related illustrations, they couldn't help but be surprised.

"You mean, connect these drones to each other to form a complete system." Zou Xiaodong looked at Wu Hao in surprise.

Yes, Wu Hao nodded: "In the past, we were too dependent on the host. All the data of the drone array needs to be transmitted to the host for processing and then redistributed to each drone. This is not only time-consuming, but also inefficient .

Our system can realize autonomous processing of data by the drone cluster. "

But limited by the load and power of the drone, the ability of the drone to process data information is very limited. Yang Fan raised his own question.

Wu Hao smiled back. "Yes, a drone is so right, but there are hundreds, thousands, or even tens of thousands, so the combined information and data processing capabilities are quite considerable."

What Wu Hao said is actually similar to the structure and calculation method of a large computer. The computer's processing power is related to its CPU. The more cores, the faster the processing speed.

This is like the same task, given to one person and to multiple people, the speed of a multi-core CPU is naturally much faster than that of a single-core CPU.

Of course, there is another possibility, that is, the operating speed of this single-core CPU is much faster than the quad-core CPU.

一些 Like some large computers, this superposition and combination method is basically used to optimize the combination of countless computing module units. So as a huge computing system, this is a supercomputer.

互连 The interconnected information processing system he proposed is based on the structural principles of large computers. It has been modified and optimized to adapt to the drone cluster network.

If it was before, he would never finish this huge project. But now, he only needs to modify the relevant information stored in his brain to get a complete set of technical information.

But with his current energy, I am afraid it will be difficult to complete in a limited time. That's why we need helpers. We only need to build the framework branches, and some fine things can be filled and refined by both of them.

"According to your proposal, this is definitely a very complicated project. In such a short period of time, do we have the ability to complete it." Zou Xiaodong worried.

He shook his hand to reveal a brazen look and said: "You can rest assured that everything is in my head."

"What joke are you doing, all in your head, do you know the complexity of this set of things?" Zou Xiaodong lost his voice.

浩 Wu Hao smiled slightly: "Do you think I'm joking?"

Zou Xiaodong and Yang Fan glanced at each other, UU read the book www.uukanshu.com and then stared at him. After watching it for about three or four minutes, I shook my head and said, "It doesn't look like it, but I still don't believe it. You can do this thing. We have lived together for four years. How can I never know that you have this skill. "

"You don't know a lot," Wu Hao said with a smile, but in fact he was nervous. He was afraid that Zou Xiaodong and Yang Fan would continue to rear-end and show themselves.

Fortunately, the two have not questioned each other. Zou Xiaodong sighed: "I'm more and more unable to see you."

"Okay, don't be emotional, work with emotion." Wu Hao interrupted the discussion and urged.

哎 "Hey, you haven't explained the real-time attitude control system yet." Zou Xiaodong asked.

浩 Wu Hao shook his head with a smile and said, "This is a category of drones, which is not used for the time being. We will go back and say, now we will work."

Seeing him reluctant to say anything, although they were a little disappointed, they got up and acted.

"Where do we start first." Zou Xiaodong asked.

Wu Hao thought for a while, and then headed for the two people: "Let's start with the construction of real-time interactive remote control system and UAV data interconnection system.

Yun Dongzi, I will send you a system framework, and you will fill in the details. "

"no problem."

Seeing that Zou Xiaodong had responded, Wu Hao sailed to the side and said, "Yang Fan, your task is also very difficult, and I will give you the hardware.

The most important part of the entire hardware is the drone body. Secondly, the ground coordinate positioning generator, and the ground remote control system.

觉得 I think you can start with the drone body that you are most familiar with. "

"OK!" I made a sound, and immediately got busy.
