In the Meiling Mountains on the outskirts of Nandu, under the shade of green trees, is a wide training ground, which is the location of the police training center of the Provincial Public Security Department. Today, the final commissioning of the electronic target report, which was specially tailored for the training center by Hanhua Industrial Company, is underway.

This set of electronic target reporter is carefully designed by Wei Jingwen, and the central control circuit uses a Z80 chip, which can manage the target reporting circuit of 16 electronic targets at the same time. Traditional shooting training requires a special target reporter to report the target, which is not only time-consuming and laborious, but also has some potential safety hazards. The system designed by Wei Jingwen is to connect each part of the target to the sensor, which part is hit, it will generate an electrical signal, various signals through analog-to-digital conversion, transmitted to the Z80 chip for processing, and then through the light signal to show the shooting results.

In addition to the traditional target reporting function, Wei Jingwen also added the function of shooting guidance ingeniously under the inspiration of Lin Zhenhua, such as being able to report the degree of deviation of the impact point from the bull's-eye, and also prompt the shooter through a certain light signal so that it can correct the shooting action.

After Lin Zhenhua got the design drawings, he took the opportunity of installing an air ring and a climbing frame for the training center of the Public Security Department to sell it to Han Tao, the director and captain of the training center. Han Tao was so moved by Lin Zhenhua that he immediately pulled him to find the director of the training department, and then found Gao Shuyuan, the director of the administrative department, and after some discussion, Gao Shuyuan and Lin Zhenhua signed a contract, and Hanhua Industrial Company built such a shooting training system for the training center, with a contract amount of 12,000 yuan.

This is another successful example of how technology can be turned into money, in fact, the hardware part of the system is not worth much at all, 16 targets, one side is conductive metal parts, the other side is wood to cushion the impact of bullets, plus brackets, etc., not even 1,000 yuan can be used. And there is nothing of value in the control circuit except for a $25 Z80 chip and dozens of dollars of memory and other components. Next to each shooting target, there is a small LCD screen for the shooter to check his or her own results, which is removed from the calculator. For these 16 displays, Lin Zhenhua purchased 16 calculators from Shin Shin Store at cost price, totaling 80 yuan.

After the whole set of equipment was built, Lin Zhenhua asked Bi Min to calculate, including labor costs, the cost of this shooting training system was less than 2,000 yuan, and Hanhua Industrial made a net profit of 10,000 yuan.

On the day of commissioning, Lin Zhenhua brought Wei Jingwen, Chu Hongyang, Peng Shaozhe and several workers, in addition to Lan Wufeng, who was addicted to guns. A group of police officers in police uniforms also watched excitedly, waiting to see the completion of this modern equipment.

"Xiaolin, the circuits have all been connected, and it's time to test the car." Wei Jingwen walked up to Lin Zhenhua and said to him.

Lin Zhenhua made a gesture to Han Tao: "Captain Han, come and cut the ribbon." ”

Han Tao readily agreed, he picked up a Type 56 semi-automatic rifle and walked to the firing position. The policeman on duty at the firing position whistled twice as customary, waved a small red flag and shook it a few times, but there was no reaction from the target area. Han Tao smiled and said to him: "With the automatic target reporter, it is estimated that you should be unemployed." ”

The policeman also smiled and said, "It's better to be unemployed, I would have thought of the police force below." ”

"How's it going, can you shoot?"

"It's okay, Captain Han."

Han Tao picked up the gun, aimed in a standing position, and then pulled the trigger. Shots rang out, and there was a ticking of chicks from the opposite side, and then several signal lights came on. Lin Zhenhua said with a smile: "It is worthy of being the captain, Ten Rings." ”

Han Tao also laughed proudly, he held the gun, slammed and slammed several shots one after another, the lights on the opposite side went on and off, turning over and over, always the same signal.

"Xiaolin, isn't our signal wrong?" Wei Jingwen stood aside and said worriedly. In fact, this system has been repeatedly debugged, and it is impossible to make mistakes, but Wei Jingwen cares about it, and it is inevitable to be a little apprehensive when he sees that the signal is always just the same group.

Lin Zhenhua comforted him and said: "Teacher Wei, it's okay, this is Captain Han's marksmanship is too good, and it is ten rings as soon as he shoots, so it's the same when he comes back." ”

Han Tao fired a few shots, turned his head to look at Lin Zhenhua, and asked with a smile: "Manager Lin, I heard that you are a veteran, do you want to come and shoot a few shots?" ”

Lin Zhenhua asked: "I want to have a good time, I don't know if it meets the regulations." ”

Han Tao said: "What are the regulations, here, I am the regulations." Test the equipment, what are you afraid of when you shoot a few shots? ”

Lin Zhenhua took off his coat, handed it to Peng Shaozhe beside him, walked off the venue by himself, and came to Han Tao's side. Han Tao handed him the gun, Lin Zhenhua took the gun, and the original soul in his body woke up, he only felt that this gun was so comfortable in his hand. Han Tao handed a row of bullets to Lin Zhenhua, who skillfully loaded them, also aimed in a standing position, and pulled the trigger on the target in front of him.

"Slam!"

"Good! Ten rings! Chu Hongyang stood behind and shouted loudly.

"Slam!"

"Good...... Nine rings! Chu Hongyang's voice was a few degrees weaker, although the nine rings are also a good result, but the captain of the Han team is the ten rings of guns and guns, and Lin Zhenhua has a nine rings, after all, he is a little faceless.

Lin Zhenhua turned around and smiled at everyone, and raised his hand to shoot again.

"Alas, Eight Rings!"

"Oops, Seven Rings!"

"What, Six Rings!"

"Five Rings!"

Hitting here, everyone can see Lin Zhenhua's intentions, he is not pursuing the position of hitting the ten rings, but testing the target signals at each position one by one. Once there was an expectation, everyone became excited again, and followed aloud to announce the meaning of the signal:

"Four Rings!"

"Three rings!"

"Two rings!"

"One Ring! It worked! ”

After ten rounds of bullets, Lin Zhenhua tried all the lights, he handed the rifle with the empty magazine to Han Tao, and said with a smile: "Captain Han, the test is complete, and the signal is correct." ”

"Manager Lin, the marksmanship is really good, admire and admire!" Han Tao took the gun and gave Lin Zhenhua a thumbs up. People who play with guns and have good marksmanship will naturally be able to gain the respect of others.

"I've won prizes, I haven't played with guns for a long time, and some of them are raw." Lin Zhenhua replied, however, he was still a little proud in his heart, his predecessor should have worked relatively hard when he was in the army, and he left such good marksmanship, which made him very face-saving.

Han Tao asked, "How about it, do you want a few more rounds?" ”

Lin Zhenhua looked back at the people he brought and said, "Captain Han, if you don't violate the rules, I want these workers and masters I brought to give a few shots, they have been greedy for a long time." ”

"It's totally possible, test, what's the right thing to do with just one target?" Han Tao said. Lin Zhenhua designed such a good set of training equipment for him, he is happy, the matter of firing a few bullets may be a big deal for others, but for him, the director of the training center, it is not a matter of words?

"Then who, go and get a few guns, so that the workers and masters can have a good time." Han Tao commanded his subordinates.

"Great!" Lan Wufeng took the lead in cheering. Peng Shaozhe, Chu Hongyang and other young workers are also gun fans, and when they grow so big, they have touched the guns of the basic militia in the factory, but they have never had the opportunity to shoot. The children of the year all grew up watching war movies, and it can be said that none of them don't like to play with guns, and when they heard that there was an opportunity to shoot, how could they not be overjoyed.

The policemen took a few guns and led the workers to the firing position, where they taught them how to load, how to aim with their guns, and how to shoot. The workers were nervous one by one, and the guns were messy, but they tested the correction system that Lin Zhenhua didn't have time to test, and the signal light on the opposite side kept flashing a prompt signal: left! Right-......

"Teacher Wei, aren't you going to shoot a few shots?" Lin Zhenhua walked up to Wei Jingwen and asked.

Wei Jingwen shook his head: "No need, I'm long past the age of gun addiction." When I was in college, I shot all the machine guns on fighter planes, not to mention rifles. ”

Han Tao listened to them on the side, and couldn't help but be surprised: "Teacher Wei graduated from what school and had the opportunity to fire machine guns?" ”

Lin Zhenhua solemnly introduced: "Mr. Wei is the chief engineer of the electronic system of our company, he is a graduate of the Department of Electronic Engineering of Beihang University, and graduated in 62 years. This time, the electronic part of your system was all designed by Mr. Wei. ”

"No wonder, no wonder." Han Tao said repeatedly, "This set of equipment is really good, we really want to thank Teacher Wei." ”

Wei Jingwen was also full of excitement: "If you think this equipment is good, then I will rest assured." I didn't think I would be able to do something for the country with my profession. However, don't thank me, if you want to thank me, just thank Xiaolin, he gave me such an opportunity. ”

"Teacher Wei, you can think more about us in the future and develop some new equipment for us, which can be regarded as supporting national defense modernization, right?"

"Definitely, definitely." Wei Jingwen said happily.

The three of them were chatting, and the shooting over there was over. The training center really has a lot of money, and everyone has dozens of bullets, which is enough to get through the addiction. Everyone couldn't fight anymore, because everyone's shoulders were red and swollen from the recoil of the gun, but everyone was smiling as if they were celebrating a holiday.

"How's it going, it's all enjoyable, isn't it?" Han Tao asked everyone with a smile.

"It's fun!" Everyone shouted in unison.

"It's not fun!" This is Lan Wufeng's voice, among these people, he is the most addicted to guns.

Han Tao said: "It doesn't matter if you don't enjoy it, you want to shoot another day, just come to me." Let's go, let's eat, but, as explained in advance, our canteen conditions are average, and the public security system is very poor, so we can't afford to invite everyone to drink. ”

"How can I let Captain Han have a treat, no one will rob me of today's meal, I will invite everyone to drink." Lan Wufeng said loudly. Actually, this sentence was originally what Lin Zhenhua wanted to say, but who knew that Lan Wufeng took the lead.

"Okay, then let Fengzi have a treat." Lin Zhenhua said, he knew that Lan Wufeng had received a dividend of 10,000 yuan or 20,000 yuan in the past six months, and it should be no problem to invite a meal. He turned to Han Tao and said, "Captain Han, do you have a better restaurant here?" ”

Han Tao replied a little embarrassedly: "There is one, a privately opened restaurant, the store is very simple, and a few dishes are fried well...... However, you are guests, how can you be embarrassed to let you break the bank? ”

Lin Zhenhua said: "Guests are not guests, you invited us to get over the gun addiction, and the comrades also volunteered to be everyone's shooting instructors. ”

"Then we'll be embarrassed." Han Tao said half-pushing, half-on-the-spot.
