Chapter 59: Solve the problem with another way of thinking
Since this was not the first time we collaborated, everyone didn’t have to be too polite and quickly got to the point.
"Crazy 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 our internal code name for this system. Your name cannot be used here."
Wu Hao laughed when he heard this and said: "This name is not bad. The crazy swarm of bees is indeed very deadly and very vivid."
"Okay, let's not talk about this anymore. Let's get down to business. Come and take a look here. Every time we do a test, we just can't pass it. We always get sluggish errors and even cause the system to crash." Zhao Hongzhe waved his hand and pointed at the screen.
The data is directed at Wu Haodao.
"Let me take a look." Wu Hao stared at the data on the screen while scrolling the mouse.
Compared with cluster array control technology at fixed sites, cluster control technology at outdoor mobile sites is more complex and more difficult.
One of the most difficult problems is how to process the information fed back and processed in real time by a large group of drones.
And in terms of positioning, the previous fixed coordinate base points are 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 huge fleet.
.
"The problem here is that there is too much navigation and positioning data, and it is difficult for the drone cluster to process it in real time, which leads to a series of slow calculations, errors, and even downtime." Wu Hao pointed to a key program on the screen.<
/p>
"But we are following your technical structure. You can use ten thousand of our drones for this performance. We only have 3,500 drones and we shouldn't have such a problem." Gao Feihang said doubtfully.
Wu Hao shook his head when he heard this 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 very fast.
And you are outdoors, and the positioning coordinate information is transmitted from Beidou in space. 3,500 aircraft need to receive 3,500 real-time positioning coordinate data, and then perform complex calculations to determine the location of each unmanned aircraft.
The real-time position and relative position of the machine are too complicated."
"To simplify data information?" Zhao Hongzhe thought thoughtfully.
Wu Hao nodded, then pointed to the content on the screen and said: "Look, these are coordinate position information, there are too many, and they are not of much use.
We can completely eliminate them and only keep the key location information for sharing."
"You mean to achieve mutual positioning and location information sharing?" Yang Xuehai had a flash of inspiration and said excitedly as if he had caught something.
Wu Hao smiled and said: "That's right, we only need to know the coordinate points of a few key locations in the drone group, and we can use these coordinate points to locate each other with other accompanying drones, thereby finding out the location of the drones at other locations.
Machine coordinate point.
In this way, the amount of calculation will be 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, with only a small number of top drones receiving satellite coordinate signals. The other drones only determine their positions based on these drones, and then form complete cluster coordinate data information.
"Zhao Hongzhe smiled. It's true that the authorities are confused and it's clear to onlookers. Why don'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 needs to be divided into groups to perform multiple tasks? What if the Beidou navigation data is received?
If something went wrong with those drones, wouldn’t the fleet lose their coordinates?"
Hehehe... Wu Hao and Zhao Hongzhe both laughed.
Wu Hao looked at him and explained: "We are not the only ones who can receive satellite navigation and positioning data from these drones. If there is a problem with these drones, then we will replace them.
This is just like the leading goose of a flock of geese. If it dies, the flock of geese can quickly choose a new leading goose to continue to lead the flight, without affecting the entire flock's team flight. Although it is important, it 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 cluster of drones that can receive positioning coordinate information, but we don’t need so many. Once necessary, we can immediately change, replace or add more.”
"This is indeed a good idea!"
Yang Xuehai praised it, and then said excitedly: "We can also let the entire fleet make independent judgments based on 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 replace the drones that receive positioning and navigation data in turn, which can also save a lot of energy.
."
"It's like this. This technology is not difficult. It can be easily implemented. 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, let you take charge. I will ask Feihang and the others to fully cooperate with you, and we will try to solve this problem as soon as possible.
The test flight will be realized as soon as possible."
"No problem, we are here to work." Wu Hao said confidently with a smile.
They are content with what they have come, and they can only leave if they finish their work quickly. In this mountain nest with difficult conditions, there seems to be no other distraction except work.
With the cooperation of professionals like Gao Feihang, Wu Hao and the others have made rapid progress. In fact, it is nothing more than modifying and optimizing the existing program, which is more cumbersome but not difficult.
It just requires time-consuming testing and continuous modification and optimization to make it suitable for the entire system and hardware equipment.
The 3,500 UAVs used this time are all fixed-wing aircraft. Therefore, the speed, control, altitude, and other data indicators are very different from those of four-axis vertical lift UAVs. This requires continuous testing and optimization. Although Zhao Hongzhe has done relevant testing and optimization before, a change in data will affect the entire system, so multiple rounds of testing are needed.
But time is limited, and they must complete the relevant test flight work before September 25th. Therefore, they must 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.
