114 Chapter 114 Infrared Scanning Radar

Half an hour later, on a grass at the top of the No. 2 pit road, two six-axis drones took off, and finally Xiao Shancha remembered a few words of Huang Jiahao's police, and did not fly towards the position of the wolf army on the opposite mountain, she flew east along the valley, and here until the triangle mountain at the end of the valley more than ten miles away, it was the territory controlled by the mercenary alliance, and she wanted to fly on her own territory It was not a violation of her promise to Huang Jiahao. Yesterday, Wang Xiaoyu integrated the infrared scanning radar software into the drone, he studied the infrared scanning radar antenna of the girl in detail, and found that this antenna cleverly placed the infrared emitting tube and the infrared receiver in front and back in the focus position of the dish antenna, and the girl told him that the surface of the dish antenna is sprayed with a polymer epoxy resin, and the reflectivity of infrared rays reaches 99.9%, so that the infrared emitting tube in front of the focus emits infrared rays. When encountering obstacles, it is reflected back, and after the focus of the dish antenna, the infrared receiver can receive a strong infrared signal, so that the detection distance of infrared is greatly improved, of course, for example, animals and other objects that will emit infrared rays themselves, their infrared signals are stronger. These received infrared signals are processed by software to form infrared images. With the help of a computer, the targets in it can be identified and tracked, and the greater the power emitted by the infrared, the more targets can be tracked at the same time.

With the help of Xiaohong and Xiaolan, two radio college students, Wang Xiaoyu converted a rotating warning light into an infrared scanning antenna, because even if it is an almighty Taobao, you can't find the kind of polymer epoxy resin that Yangniu said, fortunately he is a science and engineering man, and I still remember that the reflectivity of the silver-plated mirror in the face of infrared has reached 98%, so I asked Huang Jiahao to buy a rotating warning light at the security store of the South Umbrella, unscrewed the bulb, and replaced it with an infrared transmitter and receiver. A knock-off version of an infrared scanning antenna was made. The speed of the rotating warning light was adjusted to five revolutions per second, so that at any angle, a photo can be taken at 0.2 seconds, and although it is not smooth enough to shoot video, it is enough to indicate the low-speed drone flight at night. Of course, it's not that Wang Xiaoyu doesn't want it to scan faster, but the power carried by the small drone is limited, even if it uses a paper battery that is dozens of times more powerful than the storage power, it can't last long with more power. There is also the copycat version after all, it is a copycat version, and the detection distance is only half of the original of the foreign girl, and the farthest can only reach about a thousand meters.

Xiao Shancha didn't understand the use of installing this thing on the drone, so he took the initiative to ask her to come to the test flight, looking at her face full of anticipation, Wang Xiaoyu agreed.

As the drone slowly lifted into the air, looking at the video pictures sent back by the drone on the Yangniu computer, the little girl finally found out what is the difference between this infrared scanning radar and the previous infrared camera, first of all, the range is different, the previous infrared camera saw only a narrow angle, infrared scanning radar, what I saw was 360-degree all-round imaging. For example, an infrared camera is like a flashlight in the dark night, illuminating a circle of light, while the infrared scanning radar is like a three-kilowatt sun lamp, illuminating the entire square. The second is that the distance is different, the infrared camera can illuminate one or two hundred meters away, and the scanning radar of this cottage can already make a radius of one kilometer clear imaging.

Xiao Shancha turned his head to look at the bottom of the mountain, Ziyan Town was hidden in the night, due to the implementation of light control, the entire Ziyan Town was pitch black, looking down from the top of the mountain, it seemed that there was an uninhabited valley. She looked back at the foreign girl's computer screen, and the outline of Ziyan Town was vivid, with buildings of different heights, two winding streets, and she also found that there were some small red dots walking around on the streets, and there was no way to tell whether it was a soldier or a resident. But not all the people can't tell the difference, there are seven or eight small dots lined up and walking back and forth, isn't this the patrolling soldiers? I can't help but admire that Brother Xiaoyu is really amazing, a very ordinary jing lantern, he can also play tricks in his hands.

The foreign girl who operated the computer also felt incredible, and sighed: "Could it be that you Chinese people are born with copycat genes?" What can be copied out as soon as it is in your hands, and who will dare to sell high-tech things to you in the future? ”

Wang Xiaoyu said: "It's over, the cottage is more often a kind of helplessness, if there is a condition, who doesn't want to have your original infrared scanning radar?" Far and clear".

The foreign girl sighed and said: "I've only known you for a few days, the paper battery has been copied by you, and the infrared scanning radar has been copied by you again, God, is there anything you can't copy?" ”

Wang Xiaoyu said: "The core technology is not a copycat, the core of this set of equipment is your software, I copied it, it is a genuine piracy, I am embarrassed to say that it is a copycat." ”

Yang Niu said: "Some people say that it is copycats and piracy that have made today's China brilliant." Take a look at the products you export the most: for example, color TVs, refrigerators and air conditioners, almost no of their own core patents, they are all copycats of us and the Japanese, is there anything else you haven't copied? ”

Wang Xiaoyu smiled and said: "Intel and AMD chips, we have never been a copycat!" ”

Girl: "Phew! took a bite and said: "The ghost believes that there has been no cottage, it has been a cottage hundreds of times, and no cottage has come out, right?" ”

Wang Xiaoyu said: "Hey, this comrade, don't be so arrogant when you are in the lead, aren't you also copycating our compass and papermaking?" Did we say anything? Back then, they still took the gunpowder we invented, not only gave patent fees, but also burned our Old Summer Palace, do you see what we said again? ”

Yang Niu said: "You are a strong word, there was no patent law in ancient times, how can it be compared with now?" ”

While the two were talking, suddenly, Xiao Shancha pointed to the screen and said, "Look! What is it? ”

At this time, the drone has flown out of the kilometer, and the navigation lights can not be seen with the naked eye in the dark night, only the image taken back by the drone with infrared scanning is observed with the screen display, Wang Xiaoyu looked at the value on the flight controller, and asked in surprise: "It is only 20 meters from the ground, why do you fly so low, girl?" If you accidentally hang it on a tree, you won't be able to come back! ”

The girl pointed to the screen and said, "Brother Xiaoyu, look, what is running on the grass?" ”

Only then did Wang Xiaoyu notice that there were four red figures running on the grass on the ground, with the big ones running in front and the three small ones following closely behind, rushing forward desperately.

The foreign girl cried out in surprise, "Look, what a cute little rabbit!" ”

At this time, Wang Xiaoyu also saw that at this time there was a litter of hares, and the mother rabbit was originally taking the baby rabbit out to forage at night, but at this moment, I don't know what danger she encountered, and the startled family fled in all directions. The mother rabbit who led the way in front of her took the little rabbits to drill into the dense grass, after all, the little rabbits were weak and soon couldn't keep up, so the mother rabbit had to stop and wait from time to time, and the person stood up, kicking out of thin air with two short forelimbs, as if to alert the enemy. Next, she leads the bunnies to drill into the denser grass, a common trick used to avoid eagles in the sky, a skill passed down by her mother's mother, and tried and tested time and again. But this time it failed, because this time it was not a sharp-eyed eagle, but a drone equipped with infrared scanning equipment, unless it drilled into the hole, otherwise those grasses could not block the infrared rays emitted from its body, and it would not be able to get rid of the tracking of the small camellia.

Xiao Camellia had already disturbed the rabbit family, but she didn't realize it, she controlled the drone to chase the rabbits closely, and felt strange, and said to the foreign girl: "What are they panicking about?" Eagles don't come out at night, what are they afraid of? ”

The girl said: "They're afraid of you, you drove the drone so low, it scared them."

Xiao Shancha stuck out his tongue and said, "I see, I can't imagine that they are so bold."

Wang Xiaoyu said: "There are also bold ones, but they are all eaten by eagles and foxes!" ”

At this moment, there were a few dog barks from the side, and a black shadow quickly rushed to Xiao Shancha's side and put something at her feet. The foreign girl used a T6 strong light flashlight to shine it over, and I saw the gray wolf shaking her head and tail at Xiao Sancha, and lowering her head and rubbing between her calves. On the grass at his feet, there was a gray hare weighing two or three pounds, and blood was still flowing from the hare's throat, which seemed to have just been bitten to death. The foreign girl said helplessly: "It seems that there are still some bold hares that are eaten by hunting dogs!" ”

Xiao Shancha controlled the drone to rise to more than 100 meters in the air, wanting to stay away from the hares, so as not to frighten them again, and on the other hand, he freed his left hand, patted the head of the gray wolf and said: "The gray wolf, you are very powerful, good job!" I don't have time to cut off the rabbit's head for you right now, well, this rabbit isn't too big, so I'll give it all to you tonight! After saying that, he pointed his finger at the hare on the grass, and the gray wolf understood, his eyes lit up, and he picked up the hare on the ground and went into the woods, and went to enjoy its delicacy alone.

Xiao Camellia turned around and controlled the drone to continue to see where the nest of rabbits had gone, when suddenly, a shadow passed silently from a low altitude of more than 30 meters below the drone and hit the grass in the hillside. In the grass, there was a squeaky scream of the mother rabbit, and she hurriedly beckoned the little rabbits to hide quickly, saying that it was too late, and the black shadow had quietly flown over their heads, and instantly stretched out a pair of steel claws, grabbing a slower little rabbit like a dragonfly, the little rabbit struggled desperately, squeaked, but unfortunately the steel claws had been caught into the flesh for three points, how to struggle to get rid of? Mother Rabbit hurriedly turned around to rescue, it was too late, the black shadow flapped her wings a few times, and she had already taken the little rabbit a few meters away from the ground, and flew away diagonally.

Witnessing everything that happened on the hillside on the screen, the little girl was angry, she wanted to pretend to be an environmental activist in front of Xiaoyu's brother, and the drone had to fly farther away, so as not to disturb the rabbit's family, but she was snatched away by others, and scolded in her mouth: "It's so hateful that it is an eagle owl!" You give me back the rabbit! With that, he controlled the drone and chased forward. Eagle owls belong to the largest kind of owls, weighing seven or eight pounds is very common, some even foxes dare to catch and eat, from the equator to Siberia, they can be seen, widely distributed all over the world. Since they have to fly quietly, they are not very fast. Xiao Camellia activated the infrared scan at a high place, and soon found a red shadow flying in the southeast direction 200 meters away, and hurriedly controlled the drone to follow.

The eagle owl flying in front caught a little rabbit, originally wanted to find a place to have a good meal, on a rock, when it just wanted to land, it found a black monster chasing behind it, thinking that it was to grab food from it, surprised, hurriedly flapped its wings and flew high, and flew to the southeast at high speed. The flight speed of the eagle owl is about fifty or sixty kilometers, and the drone of the small camellia is also about 60 kilometers per hour, so that the front escapes want to accelerate and escape, and can't do it, and the back chases, and can't catch up as soon as possible. In this way, this chase and escape, going farther and farther to the southeast.
