"Why did it choose this route instead of a closer route?" Luo Kai, who had rarely spoken, asked proactively at this time.
"Because this is the optimal route." Wu Hao replied with a smile.
Luo Kai heard his answer and asked: "The best route?"
Wu Hao nodded, then pointed to the big screen and said: "Look, the drone cluster has planned a total of six flight paths, some of which are the shortest and some are the longest.
The route chosen by the drone cluster was not the shortest of the two options. Instead, it was the route with many twists and turns.
We carefully compared the terrain map and we can see that the two shortest routes are flying along the valley, which is indeed good and can avoid radar detection.
But have you noticed that there are several consecutive sharp bends less than 90°C in the valleys passed by these two routes. If a huge fleet passes through these sharp turns, it will easily cause a large number of drones to crash, so for safety reasons it abandoned this shortest route.
As for the farthest route, there is no doubt that it is too far. "
After hearing Wu Hao's words, everyone looked at the big screen and nodded. Indeed, compared to other routes, the flight route chosen by the cluster was the most suitable.
"Wait a minute, why are so many drones crashing?" Just as everyone was discussing, Yang Xuehai suddenly shouted at this time.
After hearing this, everyone looked over and saw some red dots on the screen where the drone cluster flew. This meant that a drone had crashed. If it turns into a black spot, it means that the drone has crashed and lost contact, and the black spot is the positioning point where the system last received signals.
Upon seeing this, Zhao Hongzhe frowned and asked, "Have you found anything in the high-altitude drone reconnaissance images?"
"Nothing special has been discovered yet." A technician reported.
Wu Hao looked at the screen and then raised his voice: "Bring over the video recorded by the drone equipped with a camera at the front of the fleet."
"Report, drone No. 021, No. 078 is at the forefront 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.
Everyone saw this and stared at the big screen, but they didn't notice anything unusual for a while.
Zhao Hongzhe asked: "Have you noticed any abnormalities 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 abnormalities have been found for the time being."
"The number of downed drones is still increasing, and there are currently more than one hundred." Gao Feihang anxiously reported while staring at the data on the screen.
"Xiao Wu, is there something wrong with the cluster autonomous control system?" Yang Xuehai asked worriedly at him.
Wu Hao was a little unsure when he heard this, but turned to look at Yang Fan and the others who had been staring at the data on the other side.
Yang Fan shook his head slightly at him, indicating that no abnormalities were found in the system control program for the time being.
So where is the problem?
Wu Hao stared at the video image on the big screen and thought about it. He had never seen a plane crash for no reason before.
"Mr. Zhao, if it doesn't work, just stop. We have achieved great success, there is no need to take this risk again." Yang Xuehai suggested to Zhao Hongzhe at this time.
After hearing Professor Yang's words, everyone suddenly 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 for now. We will wait until we find the problem and solve it before testing. Anyway, there is no shortage of time."
Zhao Hongzhe hesitated after hearing what the two said. He turned his eyes to Wu Hao who was still thinking and asked, "Xiao Wu, what do you think?"
After 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 and said, "What's wrong?"
"What are you thinking about?" Zhao Hongzhe asked him.
Wu Hao felt everyone's eyes focused on him, then smiled and shook his head: "Maybe, I already know the reason."
Zhao Hongzhe suddenly became interested when he heard what he said, and quickly asked: "Oh, what's the problem?"
"Have you noticed the dense vegetation and trees in the valley?" Wu Hao replied with a smile.
"You mean?" Zhao Hongzhe's eyes lit up and he suddenly realized what he was saying.
Wu Hao nodded and said: "This is not a problem with our system program and the drone at all, but the data is inaccurate.
The data we obtained, especially the topographic data, were based on mountain topographic mapping records, and little attention was paid to these tall and dense trees.
So I analyzed that our fallen drones were most likely blocked by these tall trees and vegetation, which caused the crash failure. "
"Yes, this must be the reason. The terrain and landform data we have come from the database collected and mapped before, and are not what we mapped in real time.
During this period, a tree may suddenly grow taller in these mountains, or there may be an additional building, wires, or landslides and other obstacles. This can cause a mismatch between data and reality, causing the drone to crash. "
Hearing Wu Hao's explanation, Yang Xuehai looked excited and agreed very much.
Luo Kai was slightly disappointed when he heard the introduction of the two people: "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. Under normal circumstances, we will not encounter this kind of situation.
What was tested today was only conducted under the set extreme environment.
It's easy to solve this problem, I already have two solutions here. The First UAV and existing system technology do not need to be touched, and only the latest topographic and landform surveying data needs to be imported to solve this problem.
The second is to upgrade the drone hardware and system software. UAVs can be equipped with detection radars, distance sensors or other detection equipment.
In this way, the surrounding ground information can be detected in real time when the fleet is flying. It can not only avoid these obstacles, but also accurately search, detect and attack the target location. "
Zhao Hongzhe nodded and smiled: "Xiao Wu is right, it is indeed not as complicated as you think. Our drone does lack these sensors, which is why problems occur in such unfamiliar areas."
"Compared to the first option, I am more optimistic about the second improvement option. In this way, our drone cluster 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 beside him and said with a smile on his face.
