Chapter 20: Got into trouble

Not to mention that Zheng Xiangqing had battled with various figures and broke his legs for his own future and a Canton Fair entry in Wenzhou. Let's just talk about Tan Zhenhua.
What is Tan Zhenhua doing? He is playing now, and he is playing very hilariously!
Today is the weekend. I saw a group of children, big and small, on the basketball court in the family area of ​​the institute. There was a strange thing in the middle of the crowd. This is Tan Zhenhua's new toy.
This new toy has a square belly. It looks like a plastic soap box wrapped in the middle of the iron sheet. Under the soap box, there is still a large pile of things tied with electrical insulating tape, which is tied to the soap box. , Can't see the purpose. Along the circumference of the belly, four thin arms stretched out symmetrically. The arms are still shiny with metal. It seems that the material should be made of aluminum alloy tubes. Each arm has a small rotor blade, and there are two sticks under the belly. The legs are like the landing gear of a helicopter. The material should be the same as the arm. If you must add an adjective to this thing, there is only one word to describe
"ugly"!
Tan Zhenhua held a square wooden box in his hand. On the wooden box were several push-button switches, two handles, and a long antenna. He yelled, "It's all dispersed, it's about to start!" Taking advantage of the crowd spreading out, he pressed the red button in the middle and heard a "buzz" sound, that ugly monster The 4 rotors quickly spun, followed the body and shook, and they gradually separated from the ground!
As Tan Zhenhua flicked the switch on his hand, the "buzzing" sound gradually increased, and the ugly monster actually flew higher and higher. Amidst the cheers of a large number of children, it gradually rose above the heads of the onlookers, and higher than the crowd. The roof of the hut on the side!
Tan Zhenhua controlled the ugly monster, flew out of the basketball court, and started to move along the road connecting the gate of the compound and the entrance of the work area. A group of half-old children yelled together, heads up, and chased the ugly monster. Happy as if Chinese New Year.
The movements of these children finally attracted the attention of others. Passersby kept looking up at the monster in the sky, and many people shouted in surprise: "What kind of ugly thing is that, it can fly!"
While the big guys were watching the strange together, Tan Zhenhua stared at the flashing red light on the remote control in his hand and muttered annoyedly: "This is almost out of power. It only took a few minutes to fly. Whenever there is a lithium battery available, this nickel-cadmium battery is really terrible!"
Before he finished his upset, the ugly rotors had already slowed down significantly. The body gradually lost its power and fell down with inadequate control. Only a scream was heard, and a scream came from the crowd, and then It was a messy shout: "I hit someone, I hit someone! Oh, it's bleeding, my head is smashed."
Tan Zhenhua was taken aback, and hurriedly ran forward to look, only to see a person squatting in the middle, clutching his head and humming, his heart was miserable:
"It's over, it's trouble!"
"You must stand at attention when you are beaten." The misfortune has already happened, and it's useless to run. What's more, the murder weapon is still thrown on the side, it's the ugly quadcopter.
He quickly separated the crowd and asked before walking: "I'm sorry, I'm sorry, where did it hit? I'll accompany you to the hospital quickly."
The man held his head and raised his head, saw Tan Zhenhua, and said angrily: "Which kid, what's the matter with this, hurry up and accompany me to the hospital, and then call your adult, I'll ask them to talk about it!"
Tan Zhenhua looked at the man's face, and was dumbfounded!
This man, he has never dealt with Tan Zhenhua in this life, but in the previous life, he had been tit-for-tat with him Tan Zhenhua for more than ten years.
This person is the representative Wang Zetian, the representative of the garrison who has the right to sign the inspection and acceptance of the military products, and the person who loves the thousands of old and young people in the institute so that the teeth are itchy and has to admire his professionalism!
Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh! "Tan Zhenhua was completely confused.
Don't say anything, it's important to treat people first. Fortunately, the hospital was not far away. It was only a short walk away. Tan Zhenhua didn't need the quadcopter. He hurriedly helped Wang Zetian and went straight to the hospital.
When I arrived at the hospital, the doctor on duty saw that this was an acquaintance, and hurriedly stepped forward and asked, "Representative Wang, what's wrong with you?"
I heard the representative Wang humming while holding his bleeding head, "I wanted to see something strange, who knows, let this kid smash his head."
Today, the sun must have come out from the west. Someone in this compound dared to smash the head of the military representative. This behavior is too much for the entire staff to applaud—no, is it too sad?
The doctor on duty held back a smile and found a bunch of instruments and antiseptic alcohol. First, he cut all the hair around the wound with scissors, and then cleaned the wound with alcohol. The pain caused him to pump, and then he pointed the flashlight at Wang. The representative took a picture of his pupils, and finally concluded:
It’s okay, it’s not heavy, so I nodded my scalp, and the wound is on the top of the head, and it won’t be broken. I will have two stitches and I will remove the stitches in a few days. You can't see the hair covered."
What else are you talking about, sew quickly.
The doctor here is swiftly stitching needles, and there Tan Ming and Xu Yun have heard the news and rushed.
As soon as he entered the door, Tan Ming stayed for a while. Obviously he didn’t expect that Tan Zhenhua would hit this one. This is a great god. Although Tan Ming has dealt with him countless times, it’s all about work. On personal acquaintances-can he have personal acquaintances, as far as the Wang representative's expression of staying away from strangers on business matters?
It seems that it’s hard to be good today. He quickly stepped forward and said apologetically:
Oh, sorry, I’m really sorry, I didn’t expect to smash the representative Wang. I’m sorry, I’m sorry, it’s nothing big, right? I’ll take care of this stinky boy when I look back. "
The representative Wang was surprised and immediately said in relief: "Okay, who's the kid I am so powerful, and I can be a flying brick. It turns out to be the seed of your old Tan family, that's no wonder."
Representative Wang said so, of course, there is a basis. To talk about Comrade Tan’s hands-on ability, it’s really not covered. If you can run and sound at home, you either do it yourself or repair it yourself. Although you specialize in direction display, the unit can be as large as a radar or as small as an oscilloscope. , Even if someone’s bicycle, sewing machine, radio, etc. are faulty, it is correct to ask him to fix it. That craftsmanship is well-known. Therefore, no one would be surprised that the children of the old Tan family can fly out of the sky and bricks.
Representative Wang said it logically. Tan Ming heard the sweat and immediately got down, cursing in his heart: "You said you are a stinky kid, what is bad for playing, you can play airplanes, you can just play airplanes, and you still smashed. If there are people, you don't have to pick them, you dare to smash the military representatives!
That's a military representative. Even the head of the office must be polite when they meet. All the equipment inspection and acceptance of the whole institute must be signed by others. You are not the people who are hitting, but the jobs of all the employees are hit! Your father, I am in a big trouble this time, and tomorrow will surely become the laughing stock of the whole institute! I didn't say anything, I will give you a discount on your legs when you go home! "
He thought in his heart, he kept on being with his mouth, and he was not idle, he was going to smoke Tan Zhenhua when he came up!
The hero Tan Zhenhua didn't suffer from the immediate loss. Seeing that his father was about to come up and pump himself, he hurriedly flashed and rushed behind his mother, shouting: "Dad, I know I was wrong, I really didn't mean it." After all, Xu Yun loved her son. He opened his arms and stopped his man, yelling: "Hey, how can you beat the child."
In fact, Xu Yun knew in her heart that Tan Ming was just acting, can she still see the double acting of father and son? But, after all, it is human nature to make others bleed, and it is natural to give Wang Representative a step down, so the family of three pulls together.
Representative Wang waited for the doctor to sew the stitches for him, but became quiet. He sat aside with a smile and watched these people acting in front of him. After the excitement was enough, he came up to be the peacemaker: "It's all right, Tan Gong , I don’t think Xiao Tan did it on purpose, and I blamed me for being careless, just passing by over there."
Tan Ming was waiting for his sentence, and he hummed: "You stinky boy, wait, go home and clean you up. The king represents you not to speak for him."
Representative Wang ignored that Tan Ming was still performing there, and he pulled Tan Zhenhua over and said, "Student Xiao Tan, what you did that is a thing, I looked very interesting, what about it? I didn’t see it clearly just now, just take it over. Look."
Tan Zhenhua patted his head: "Oops, the things are still thrown on the road, Uncle Wang, you want to see, I'll get it for you right away." After speaking, he ran away.
Representative Wang was happy when he heard the words: "Well, I smashed my head and picked up a half-old nephew. This business is worth it! This little devil, his brain is so good! So I called my uncle and wanted to fix him. Sorry to start!"
While talking, Tan Zhenhua had already ran back with the 4-rotor, but with a little face crying, he said: "Uncle Wang, I will pick up the flying bricks, but the remote control is nowhere to be found. Whose is it? The child picked it up to play, it’s useless if he wants it? Without this host, what would he want the remote control for? Really, who’s hapless kid, all the rags will be recycled."
Representative Wang laughed and said: "I was so irritated just now that I randomly named you this thing. You really called it. You told me about you baby."
When Tan Zhenhua heard this, he immediately became energetic. Regardless of whether it was in the hospital, he pointed to the tattered pile and said, "Uncle Wang, I call this a 4-rotor drone. It has 4 aluminum alloy cantilevers. , Here, there are 4 low-voltage DC motors on the cantilever. The motor has a rated voltage of 12 volts. It is currently made of ferrite permanent magnet material and copper wire coil. The motor is equipped with a rotor and the material is also aluminum alloy. The working principle is Like helicopters, the rotation directions of the 4-rotors are opposite to each other, which can cancel each other's torsion, which helps balance in flight.
This soap box is equipped with a flight control system, and there is an electronic level in it. At present, I use an inductive type. It can feed back a set of electrical signals to indicate the status of the entire drone, and then use the flight control computer to adjust The current output of each motor, so that the output power of each motor can be adjusted, so as to realize the actions of rising, falling and turning.
Here is the core of the entire 4-rotor UAV, the flight control computer. Its core is a Z80 CPU, in which a program is written to determine how much output power each motor needs in each state, and then it is realized through this power control circuit. The bottom one is the battery. In order to ensure the output, I use a nickel-cadmium rechargeable battery. The connection method is 2 parallel 8 strings, a total of 16 batteries, but this battery is too unusable. Such a heavy battery can only fly. It hung up in less than 5 minutes. "
Representative Wang concluded after listening, "After talking for a long time, isn't this just a model airplane?"
Tan Zhenhua argued: "This is a 4-rotor UAV, how can it be called a model airplane? This thing will be of great use in the future."
Isn't it? In Tan Zhenhua's previous life, this little drone flew everywhere in the world, especially its base camp, Huaxia, where there are no drones floating in the sky, you are embarrassed to call it a tourist attraction!
Moreover, this gadget has invaded the military arsenal of Star-Spangled Banner Rice Lijian in droves! As a result, the U.S. chief issued a special chief's order: "In order to prevent information leakage, it is strictly forbidden for the country's military to purchase and use China UAVs privately!"
China's UAVs occupy 80% of Bluestar's civilian market share!
Even when the British Empire’s new aircraft carrier, Queen Elizabeth, which was once known as the sun never set, was launched, a UAV made by China came to watch, and, unexpectedly, it landed on the aircraft carrier, landing~ landing~了~, landing, landing,, (the important thing to say three times!) and became the first aircraft to land on the aircraft carrier.
Representative Wang said in a strange way: "Oh? Is this little thing so magical? What's the use of it? Come and listen."
