Military Technology

Because this is not the first time for cooperation, everyone will not have too much politeness, and soon enter the topic.

"Buzz system?" Wu Hao wondered, seeing the name on the data.

Zhao Hongzhe nodded: "Yes, this is the internal code of this system. Your name is not used here."

Wu Hao said with a smile: "The name is also good, the mad bee colony is indeed deadly and very visual."

"Okay, don't talk about that, let's talk about business. You come to see here. Every time we test, we just can't get through. It always shows a dull error and even causes the system to crash." Zhao Hongzhe waved and pointed at the screen. The data is directed at Wu Hao.

"Let me see." Wu Hao scrolled and stared at the data on the screen.

Compared with the cluster array control technology for fixed sites, the cluster control technology for outdoor mobile sites is more complicated 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.

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

"This problem, too many navigation and positioning data, the drone cluster is difficult to process in real time, resulting in a series of subsequent calculation 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. We shouldn't have such a problem at 3,500." Gao Feihang said doubtfully.

浩 Wu Hao heard a shake and said, "This is different. We are on a fixed site, the coordinate position is relatively fixed, and the transmission distance is short. Therefore, the connection is closer and the data processing speed is faster.

You are out of the room. The positioning coordinate information is transmitted by Beidou in space. The 3,500 aircraft needs to receive 3,500 real-time positioning coordinate data, and then performs complex calculations to determine the real-time position and relative position of each drone, which is too complicated. "

"Simplify data information?" Zhao Hongzhe thoughtfully.

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

We can completely remove them and only retain key location information for sharing. "

"Do you mean to achieve mutual positioning and share location information?" Yang Xuehai flashed, as if he had caught some excitement.

Wu Hao said with a smile: "Yes, we only need to know the coordinate points of several key positions in the drone group, and we can use these coordinate points to position each other with other accompanying drones, so as to find that there are no people in other positions. Machine coordinate points.

As a result, the amount of calculations has been greatly reduced. "

"First establish the backbone coordinate base points, and then use these base points to find the position of other drones, 1? 2, 2? 4, 4? 8, so that they 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. Other drones are just based on these drones to determine their own position, and then form a complete cluster coordinate data information. "Zhao Hongzhe smiled. It was indeed the authorities who obsessed the spectators. Why didn't they change their minds and think about this issue?"

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 decentralized grouping to perform multiple tasks? In case of receiving Beidou navigation data Those drones have problems. Do n’t the fleet lose their coordinates? "

Hehehehe ... Wu Hao and Zhao Hongzhe laughed.

Wu Hao looked at him and explained: "We are not the only ones that can receive satellite navigation positioning data. If there is something wrong with these drones, then we should change another batch.

This is like the head geese leading the flock of geese. It is dead. The flock of geese can also quickly select new head geese to continue to lead the way. It will not affect the team flight of the entire flock. It is important to say that it is important, because it will lead the entire group of geese to fly. It's not important or important, because it can be replaced at any time.

We have the entire cluster of drones that can receive positioning coordinate information, but we don't need that much. Once needed, changes can be replaced or added immediately. "

"This is indeed a good idea!"

Yang Xuehai praised it, and then excited: "We can also let the entire fleet make autonomous judgment based on demand.

If the terrain is complex and the signal is weak, we can add more drones to accept the relevant position data. Under normal circumstances, we can take turns replacing drones that accept positioning and navigation data ~ www.novelmtl.com ~ This can also save a lot of energy. "

"It's like this, this technology is not difficult, it can be easily implemented, and then it can be directly embedded into the entire system to replace the previous program." Wu Hao smiled.

The crowd nodded when he heard what he said, and Zhao Hongzhe said to him, "Since Xiao Wu is familiar with you, let it be your responsibility. I ask Feihang to cooperate with you fully. Early test flight. "

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

As soon as they come, they will be safe. They can only leave if they finish their work quickly. In this difficult mountain nest, there seems to be no distractions other than work.

With the cooperation of Gao Feihang and their professionals, Wu Hao and they are making rapid progress. In fact, it is nothing more than modifying and optimizing the existing program. Although it is tedious, it is not difficult.

不过 It just needs to take time to test later, and then continuously modify and optimize it to fit the entire system and hardware equipment.

The 3,500 drones used this time are all fixed-wing aircraft. So in speed, control, altitude, and other data indicators are very different from the four-axis vertical lift drone.

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

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