Since this was not the first time we collaborated, everyone didn’t have to be too polite and quickly got down to business.
"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 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 pointed 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 by a large group of drones in real time.
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 a kind of inertial navigation, but it is not suitable for such a large 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.
"But we are following your technical structure. You can use ten thousand of our drones for this performance. We only have 3,500 companies 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 doing it outdoors, and the positioning coordinate information is transmitted from Beidou in space. It is too complicated for 3,500 drones 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 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 to share. "
"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 the other accompanying drones, thereby finding out the location of the drones at other locations. machine coordinate point.
In this way, the amount of calculation 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, with only a small number of drones at the top receiving satellite coordinate signals. Other drones only determine their position 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 question: "Although this is a cluster, it is not a stable group. What if the cluster needs to be dispersed and grouped 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 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, 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 leading the flight, without affecting the flight of the entire flock. It is important to say it is actually important, because it will lead the entire flock of geese to fly. It doesn't matter if it's 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, changes, substitutions or additions can be made immediately. "
"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 take turns replacing the drones that receive positioning and navigation data, 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 after hearing 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.
Once they've come, they'll be in peace. They can only leave if they finish their work quickly. In this harsh mountain home, there seemed to be no other distractions except work.
With the cooperation of professionals like Gao Feihang, Wu Hao and the others made rapid progress. In fact, it is nothing more than modifying and optimizing existing programs. Although it is more cumbersome, it is not difficult.
It just requires time-consuming testing later, and then continuous modification and optimization to make it fit the entire system and hardware equipment.
The 3,500 drones used this time are all fixed-wing aircraft. Therefore, there is a big difference between speed, control, altitude, and other data indicators and four-axis vertical lift drones.
This requires continuous testing and optimization, although Zhao Hongzhe has already done relevant testing and optimization before. But a change in data will affect the entire system, so multiple rounds of testing are required.
But time is limited, and they must complete the relevant test flights before September 25th. Therefore, we must seize the time and race against time to complete relevant optimization and modification tests, and prepare relevant test flights as soon as possible.
