Chapter 59: Solve the problem with a different way of thinking

Because it was not the first time to cooperate, everyone didn't have too much politeness and quickly got to the point.

"The Wild Bee System?" Wu Hao couldn't help but wonder when he saw the name on the information.

Zhao Hongzhe nodded and said: "Yes, this is the code name of this system within us, and your name is not used here." ”

Wu Hao smiled when he heard this: "This name is not bad, the crazy bee colony is indeed very deadly, very vivid." ”

"Okay, let's get down to business. If you look at it here, every time we conduct a test, we just can't get by, and we always have sluggish errors, and even cause the system to crash. Zhao Hongzhe waved his hand, and then pointed to the data on the screen and said to Wu Hao.

"I'll see." Wu Hao scrolled his mouse while staring at the data on the screen.

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

One of the most difficult problems is how to process the real-time feedback and processing of the information processed in real time by a large fleet of drones.

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

"The problem is that there are too many navigation and positioning data, and it is difficult for UAV swarms to process in real time, which leads to 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 my 10,000 drones for this performance, and we are only 3,500 companies that should not have such a problem." Gao Feihang said suspiciously.

Wu Hao shook his head when he heard this: "This is different, we are on a fixed field, the coordinate position is relatively fixed, and the transmission distance is also very short. As a result, the connection is closer and the data is processed quickly.

And you are out of the outdoors, and the positioning coordinate information is transmitted by Beidou in space. It is too complicated for 3,500 aircraft 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 drone. ”

"Want to simplify your data?" Zhao Hongzhe was thoughtful.

Wu Hao nodded, then pointed to the content on the screen and said, "You see, these are all coordinate location information, there are too many, and they are not too useful."

We can weed them out and keep only the key location information for sharing. ”

"You mean to achieve mutual positioning, to achieve location information sharing?" Yang Xuehai had a flash of inspiration, as if he had caught something and said excitedly.

Wu Hao said with a smile: "That's right, we only need to know the coordinate points of several key positions in the drone group, and we can use these coordinate points to locate each other with other accompanying drones, so as to find the coordinate points of drones in other locations."

In this way, the amount of computing is greatly reduced. ”

"First establish the backbone coordinate base points, and then find the positions of other UAVs through these base points, 1⋉2, 2⋉4, 4⋉8, and so spread out layer by layer.

The entire transmission structure is like a pyramid, and only a small number of UAVs at the top receive satellite coordinate signals. Other UAVs are just based on these UAVs to determine their own position, and then form a complete cluster coordinate data information. Zhao Hongzhe smiled. It is 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 be distributed and grouped to perform multiple tasks? In case something goes wrong with those drones that receive Beidou navigation data, won't the swarm lose its coordinate position? ”

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

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

This is like the head goose leading the way, it dies, and the flock can quickly select a new head goose to continue to lead the way, and it will not affect the team flight of the entire flock of geese. If you say it's important, it's actually important, because it will lead the whole flock of geese to fly. It doesn't matter if you say it's not important, because it's always ready to be replaced.

We have a whole swarm of drones that can receive positioning coordinate information, but we don't need so much. If necessary, changes can be made immediately to replace or add. ”

"That's a good idea!"

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

If the terrain is complex and the signal is weak, we can add more drones to accept relevant location data. In general, 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 is easy to implement, and when the time comes, 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, and Zhao Hongzhe said to him: "Xiao Wu, since you are familiar with this fast, then let you be in charge." I asked them to fully cooperate with you, and we will strive to solve this problem as soon as possible and realize the test flight as soon as possible. ”

"No problem, we're here for work." Wu Hao said confidently with a smile.

They can only leave if they finish their work quickly. In this harsh mountain nest, there seems to be nothing else to distract from except work.

With the cooperation of Gao Feihang and their professionals, Wu Hao and their progress are very fast. In fact, it is nothing more than modifying and optimizing the existing program, although it is more cumbersome, but it is not very difficult.

It's just that it takes time to test and then continuously modify and optimize it to fit the whole system and hardware devices.

The 3,500 drones used this time are all fixed-wing aircraft. So in terms of speed, handling, altitude, and some other data indicators, there are big differences with four-axis vertical lifting drones.

This requires continuous testing and optimization, although Zhao Hongzhe has already done relevant testing and optimization before. However, a change in one piece of data will affect the entire system, so multiple rounds of testing are required.

However, time was limited, and they had to complete the relevant test flight work by September 25. Therefore, it is necessary to seize the time and race against time to complete the relevant optimization and modification tests, and prepare the relevant test flight work as soon as possible.
