"Why did it choose this route instead of the closer route?" Luo Kai, who has been rarely speaking, asked at this time.

"Because this is the best route." Wu Hao replied with a smile.

Luo Kai heard his answer and asked: "The best route?"

Wu Hao nodded, then pointed at the big screen and said, "Look, the drone swarm has planned a total of six flight paths, of which there are the shortest and the longest.

The one chosen by the drone swarm is not the shortest of the two schemes, but this one has many twists and turns.

We can see from the topographic map that the two shortest routes are flying along the valley, which is really good, and it can also avoid radar detection.

But have you noticed that there are several consecutive sharp bends less than 90°C in the valleys that these two routes pass through. If the huge group of aircraft passes through these sharp bends, it is easy to cause a large number of drone crashes, so it gave up this shortest route for safety reasons.

As for the farthest one, there is no doubt that the line is too far. "

After hearing Wu Hao's words, everyone looked at the big screen and nodded. Indeed, compared to other routes, this flight route chosen by the cluster is the most suitable.

"Wait a minute, why are so many drones crashing?" Just as everyone was discussing, Yang Xuehai suddenly shouted.

Everyone heard the words and looked over, and saw some red dots on the trajectory of the drone cluster on the screen, which means that a drone has fallen. If it turns into a black spot, it means that the drone has crashed and lost contact, and the black spot is the last location where the system receives the signal.

Seeing this, Zhao Hongzhe frowned and asked, "Has there been anything found in the high-altitude drone surveillance images?"

"Nothing special has been found for the time being." A technician reported in a report.

Wu Hao looked at the screen, and then raised his voice: "Transfer the video recorded by the drone with the camera in the front of the fleet."

"Report, the drone No. 021, No. 078 is in the front position of the fleet, and the video image has been transmitted to the big screen."

At the same time, surveillance video images from the perspective of the two drones appeared on the large TV screen.

Seeing this, everyone stared at the big screen, but they didn't notice anything unusual for a while.

Zhao Hongzhe asked, "Has there been anything unusual at the observation points along the way?"

"It is reported that the drone passed through the valley area and was out of the field of view of most observation points. Only a few observation points can still track the flight status of the drone cluster, but the distance is too far, and no abnormality has been found for the time being."

"The number of crashed drones is still increasing, and there are currently more than 100." Gao Feihang stared at the data on the screen and reported anxiously.

"Xiao Wu, is there something wrong with the cluster autonomous control system?" Yang Xuehai worried about him.

Wu Hao was also a little clueless when he heard the words, but turned to look at Yang Fan and the others who had been staring at the data on the other side.

Yang Fan slightly shook his head at him, indicating that nothing abnormal was found in the system control program.

Where is the problem?

Wu Hao stared at the video image on the big screen and pondered, he had never seen a plane crash for no reason before.

"Elder Zhao, stop if you can't do it. We have already achieved great success, and there is no need to take this risk." Yang Xuehai suggested to Zhao Hongzhe at this time.

Hearing Professor Yang's words, everyone immediately focused their attention on Zhao Hongzhe.

At this time, Luo Kai on the side also said: "I think Mr. Yang is right, let's stop it for now. We will test it after we find the problem and solve it.

Not bad for this time anyway. "

Zhao Hongzhe hesitated after hearing the words of the two. He turned his eyes to Wu Hao who was still thinking and asked, "Xiao Wu, what is your opinion?"

Hearing Zhao Hongzhe's words, everyone turned their attention to him again. But now Wu Hao is still immersed in his own thoughts.

"Xiao Wu?"

"Ah?" Wu Hao was awakened: "What's wrong?"

"What are you thinking?" Zhao Hongzhe asked him.

Wu Hao felt the eyes of everyone focusing on him, then smiled and shook his head: "Perhaps, I already know the reason."

Zhao Hongzhe suddenly became interested when he heard his words, and hurriedly asked, "Oh, what's the problem?"

"Have you noticed those dense vegetation trees in the valley?" Wu Hao replied with a smile.

"You mean?" Zhao Hongzhe's eyes lit up and he reacted at once.

Wu Hao nodded and said, "This is not a problem with our system programs and drones at all, but inaccurate data.

The data we obtained, especially the topographic data, were based on the topographic mapping of the mountains, and these tall and dense trees were rarely noticed.

So I analyzed that our falling drones are likely to be blocked by these tall trees and vegetation, which caused the falling failure. "

"That's right, it must be the reason. The topographic data we have come from the database that we collected and surveyed before, not what we surveyed and mapped in real time.

During this period, a tree may suddenly grow in these mountains, or there may be an additional building, power lines, or obstacles such as landslides. This can create a mismatch between the data and reality, causing the drone to crash. "

Hearing Wu Hao's explanation, Yang Xuehai was excited and agreed.

Hearing the introduction of the two, Luo Kai was a little disappointed and said: "So, our technology needs to be optimized and improved."

Seeing this, Wu Hao smiled and comforted: "Actually, it's not as complicated as everyone thinks, and we don't usually encounter such a situation.

The content tested today is only carried out in a set limit environment.

It is easy to solve this problem, I already have two solutions here. The first UAV and the existing system technology do not need to be moved, and this problem can be solved only by importing the latest topographic and landform mapping data.

Second, upgrade the UAV hardware and system software. The drone can be equipped with detection radar, distance sensor or other detection equipment.

In this way, the surrounding ground information can be detected in real time when the aircraft group is flying, which can not only avoid these obstacles, but also accurately search, detect and attack the target position. "

Zhao Hongzhe nodded and smiled: "Xiao Wu is right, it's not as complicated as you think. Our drones are indeed missing this part of the sensor, so it will cause problems in such an unfamiliar area."

"Compared with the first scheme, I am more optimistic about the second improvement scheme. In this way, our drone swarm can perform tasks in unfamiliar areas at any time, greatly increasing its use environment and scope, and also It can increase its power." Yang Xuehai nodded, looking at Wu Hao who was beside him with a smile on his face.
