Military Technology

Because it is not the first time to cooperate, everyone did not have too much courtesy, and quickly entered the topic.

"Crazy Bee System?" Wu Hao couldn't help but wonder when he saw the name on the document.

Zhao Hongzhe nodded and said: "Yes, this is the code name of this system in our internal, your name can't be used here."

Wu Hao said with a smile: "This name is not bad, the mad bee colony is indeed deadly and very vivid."

"Okay, let's not talk about this, let's get down to business. Come and take a look here, every time we conduct a test, we can't get through it. We always get slow errors and even cause the system to crash." Zhao Hongzhe waved his hand, and then pointed to the screen. The data directed at Wu Haodao.

"Let me see." Wu Hao stared at the data on the screen while scrolling the mouse.

Compared with the cluster array control technology of the fixed site, the cluster control technology of the outdoor mobile site is more complex and difficult.

One of the most thorny problems is how to process the information fed back and processed in real time by the huge swarm of drones.

And in terms of positioning, the previous fixed coordinate base point is definitely useless, so satellite navigation technology and digital terrain matching technology are used for positioning. Of course, there is also an inertial navigation, but it is not suitable for such a large fleet.

"The problem with this is that there is too much navigation and positioning data, and it is difficult for the drone cluster to process it in real time, resulting in a series of slow calculations and errors, and even downtime." Wu Hao pointed to a key program on the screen.

"But we are using your technical structure. You can use 10,000 drones for this performance. We are only 3,500 companies and shouldn't have such a problem." Gao Feihang said in doubt.

Wu Hao shook it and said: "This is different, we are on a fixed site, the coordinate position is relatively fixed, and the transmission distance is also very short. Therefore, the connection is closer and the data processing speed is fast.

And you are outdoors, and the positioning coordinate information is transmitted from the Beidou in space. 3,500 aircraft need to receive 3,500 real-time positioning coordinate data, and then perform complex calculations to determine the real-time position and relative position of each UAV, which is too complicated. "

"Want to simplify the data information?" Zhao Hongzhe thought thoughtfully.

Wu Hao nodded, then pointed to the content on the screen and said, "Look, these are all coordinate and position information, too much, and not too useful.

We can completely eliminate them and keep only key location information for sharing. "

"You mean to achieve mutual positioning and share location information?" Yang Xuehai flashed a flash of light, as if he had caught something excited.

Wu Hao said with a smile: "Yes, we only need to know the coordinate points of several key positions in the drone swarm, and then we can use these coordinate points to locate each other with other accompanying drones, so as to find out that there is no one in other positions. machine coordinates.

In this way, the amount of computation is greatly reduced. "

"First establish the backbone coordinate base points, and then use these base points to find the positions of other drones, 1-2, 2-4, 4-8, and spread out layer by layer.

The entire transmission structure is like a pyramid, and only a small number of drones at the top receive satellite coordinate signals. Other UAVs only determine their position based on these UAVs, and then form a complete cluster coordinate data information. "Zhao Hongzhe smiled. It's true that the authorities are obsessed with bystanders, so why didn't they think about this issue in a different way?

Gao Feihang thought for a while and asked his own question: "Although this is a cluster, it is not a stable group. What if the cluster is to perform multiple tasks in distributed groups? Those drones have problems,

Didn't the fleet lose its coordinate position? "

Hehehe... Wu Hao and Zhao Hongzhe all laughed.

Wu Hao looked at him and explained: "We are not the only drones that can receive satellite navigation and positioning data. If there is a problem with these drones, we will replace them.

This is like the head goose that leads the way in a group of geese. When it dies, the group of geese can quickly select a new head goose to continue to lead the way, and it will not affect the flight of the whole group of geese. Saying it is important is actually important, because it will lead the entire flock of geese to fly. It is not important to say it is not important, because it can be replaced at any time.

We have an entire swarm of drones that can receive location coordinates, but we don't need that much. Changes or additions can be made immediately as needed. "

"This is indeed a good idea!"

Yang Xuehai praised and said excitedly: "We can also let the entire fleet make independent judgments according to the needs.

If the terrain is complex and the signal is weak, we can add more drones to receive relevant location data. Under normal circumstances, we can take turns to replace the drones that receive positioning and navigation data, which can also save a lot of energy. "

"That's right, this technology is not difficult, it's easy to implement, and it can be directly embedded into the entire system to replace the previous program." Wu Hao said with a smile.

Everyone nodded when they heard his words, Zhao Hongzhe said to him: "Xiao Wu, since you are familiar with this fast, let you take care of it. I will let Feihang and the others cooperate with you fully, and let's try to solve this problem as soon as possible. Test flight soon."

"No problem, we are here to work." Wu Hao said with a smile.

As long as they come, they can leave. Only when the work is finished quickly can they leave. In this tough mountain nest, there seems to be no other distraction besides work.

With the cooperation of Gao Feihang and other professionals, Wu Hao and the others made rapid progress. In fact, it is nothing more than modifying and optimizing the existing program. Although it is more complicated, it is not difficult.

It's just that it takes time to test, and then constantly modify and optimize to make it fit the entire system and hardware devices.

The 3,500 drones used this time are all fixed-wing aircraft. Therefore, there is a big difference between the speed, control, height, and other data indicators and the four-axis vertical lift drone.

This requires continuous testing and optimization, although Zhao Hongzhe has done related testing and optimization before. But a data change will affect the entire system, so multiple rounds of testing are required.

But time is limited, and they must complete the relevant test flight work before September 25th. Therefore, we must hurry up to complete the relevant optimization and modification tests, and prepare for the relevant test flight work as soon as possible.
