In the capital, in the compound of the Municipal Public Security Bureau, 10 large police drones were lined up, and the surrounding policemen pointed at the 10 drones, all of them curious. Pen, fun, and www.biquge.info

No wonder they are curious, because compared to the civilian drones in their impression, these 10 drones are too big: 6-axis structure, the diagonal wheelbase between the two electric motors is as high as 33 meters, which is equivalent to the size of an Alto car, and much larger than the aerial photography drones that can be seen today.

Big,The function is naturally extraordinarily powerful,Look at the multiple zoom cameras arranged around the fuselage,This guy not only has a 360-degree viewing angle without dead ends,Even when a camera conducts large-scale monitoring of a certain area,You can also mobilize other cameras to focus and amplify a specific target in the area,This function is especially practical when performing some surveillance and capture tasks。

Several senior leaders of the Capital City Bureau who were with Lin Zheng also looked at these "huge" drones with curiosity, and Deputy Director Zhao Fei said with a smile: "In the past, we always envied that the American police could be equipped with helicopters to patrol the sky and arrest criminals, but I didn't expect that the police in our country have also begun to equip aircraft." ”

"Yes," Lin Zheng took over and said with a smile: "I think we are one step ahead of the Americans." ”

"Oh, what do you say?" As soon as Lin Zheng said this, not only Zhao Fei was curious, but other leaders of the city bureau were also curious.

Lin Zheng said: "According to our statistics, the United States has been equipped with police helicopters since the 60s, and more than 30 helicopters have fallen in the United States, killing more than 60 people and injured more than 100 people. ”

The real meaning of this statement is "it is troublesome to die people", and the leaders of the police station immediately nodded their heads, and they were concerned about Lin Zheng's words: in China. As long as there are no dead people, no matter how big a thing is, it doesn't matter how big it is, but as long as there are dead people, even if no one takes the opportunity to toss. That is also a big deal, the above has always been opposed to the police whether to equip police aircraft, in addition to financial reasons, I have to say that "fear of death" actually occupies a considerable factor.

Director Lei Tian touched his head and said approvingly: "That's right. Compared to manned aircraft, the advantages of UAVs in this regard are too great...... Well, Mr. Lin, these drones of your company can meet the requirements of our police, right? ”

Lin Zheng said with a smile: "Thunder Bureau, you can rest assured, as the world's most technologically advanced police civilian UAV research and development company, our company's UAV can not only fully meet the requirements of our police, but also exceed many performances." ”

"Oh?" Lei Tian raised his eyebrows, but he was a little unconvinced, and glanced back at everyone. said with a smile: "Mr. Lin, I won't tell you, in our opinion, as long as your drone can fully meet the requirements of the first sequence we put forward and meet the requirements of the second series of 80, it is very good, you say that not only can you do it all, but also surpass?" Hehe...... To tell you the truth, I don't believe it. ”

"I can understand that you are also responsible for your work." Lin Zheng said that he was not surprised by Lei Tian's words, which was really a condition put forward by the capital police at the beginning. Even in Lin Zheng's opinion, it was a bit harsh: "But I won't tell you, we really did it, I don't believe you can just check it." ”

They divided the conditions into two sequences, the first of which had to fulfill all the requirements. This includes 15 to 2 hours of battery life, more than 2 mbps of data transmission bandwidth, multiple focusable cameras that can automatically perform fixed-line patrol tasks, etc., in the case of drone technology in 2001, and considering the price of no more than 500,000 each, these conditions are not exaggerated.

Among these requirements, the most difficult is the requirement for battery life, with the performance of today's batteries. If an electric drone wants to achieve a range of 15 to 2 hours, it is simply impossible to use a flywheel battery unless it is used, but considering the price factor, it is impossible to use a flywheel battery.

In the end, after repeated trade-offs, the drones designed for the police all adopted the power mode of "80cc ultra-light piston aero engine generator electric motor", and were equipped with a set of 15,000 mAh 18650 lithium-ion battery pack for power balance between the motor and the generator.

This ultra-light piston aero engine with a displacement of only 80cc is mostly used for power parafoil and power delta wing, only 125 kg of weight but can burst out of 115kw of powerful power, can generate 95 kWh of electricity per hour, of course, such a perverted performance, the price is naturally quite expensive, the unit price of 4000 US dollars can even buy several Lianchuang Technology is now self-produced film and television aerial photography drones.

But in Lin Zheng's view, it is worth it, after using this engine as the prime mover for the generator, the maximum endurance of the drone can reach 3 hours, far exceeding the 15 to 2 hours endurance requirements of the police, which is not only enough to support the police's regular patrols on some key routes, but also enough to support the police's major policing, such as the arrest of major criminals, fixed-point tracking, fixed route patrols and other tasks.

"Huh? So you really did it? Lei Tian was suddenly a little moved, he thought that Lianchuang Technology was impossible to do, but Lin Zheng's confident appearance made him a little uncertain: "In this case, tell me what else you have done?" ”

"In addition to the requirements of our police, we have also added a GPS automatic positioning system, with the help of this system, not only can the drone fly according to the established route, but also can do a key return, automatic take-off, automatic landing, and automatically record the current longitude and latitude of the flight, of course, the drone operator of the drone's power, flight altitude, speed, longitude and latitude in the map and other states are also clear at a glance," Lin Zheng snapped his fingers and said to Lei Tian: "Oh, that's right, Considering the security of some major outdoor activities, such as large gatherings of football matches, we have also set up a fixed point and fixed altitude hovering function, and the whole process can be recorded. ”

"You have a GPS positioning system installed?" Lei Tian was really surprised, and said movingly: "Is it the Americans' global satellite positioning system?" ”

In China in 2001, even within the police, many people didn't know about the GPS of the Americans, but now, Lin Zheng has actually installed the GPS system of the Americans into their drones?

Not only Lei Tian was surprised, but other leaders of the city bureau were also surprised, the city bureau did not require Lianchuang Technology to install a GPS system, or rather, everyone didn't think about it at all, a director looked at Lin Zheng with a suspicious face, and asked himself: "GPS system: The military positioning system of the Americans, will they be willing to give you their GPS system?" ”

This question also represents the voice of the vast majority of city bureau leaders: GPS, that's the military system of the U.S. military, how can you Lianchuang Technology let the Americans open the back door to you?

"It's not that we can't use it," Lin Zheng smiled honestly and explained: "The one you are talking about is a military positioning system, the positioning accuracy is very high, of course the Americans can't use it for us, but we use the civilian part of GPS, this part is open to the world, as long as you buy the positioning chip of the Americans, any civilian equipment can use this GPS system, but compared with the military system, the positioning accuracy of the civilian system is much worse, about 15 to 20 meters, However, with the help of the revised map, there is no need to worry about any problems. ”

"And such a thing? Americans are so generous? ”

A group of public security leaders at the deputy department level looked at each other one by one, according to their usual way of understanding, if we had this kind of system, it would definitely not be open to foreigners, right? How dare the Americans do this?

Lin Zheng can't say how much benefit the open civilian GPS system brings to the Americans every year, not to mention that it's useless to say, said: "The Americans are actually doing this mainly to sell this positioning chip, well, now the Americans sell this civilian-grade positioning chip and all kinds of electronic equipment equipped with positioning chips around the world, and they can sell tens of billions of dollars a year, and the Americans expect that in 10 years, a huge market with an annual output value of more than 100 billion US dollars will be formed, after all, it is capitalism. How could an American put such a large sum of money and not earn it? ”

After a pause, Lin Zheng added: "This is not what I said, it is the conclusion reached by the RAND think tank in the United States after analyzing the market development of GPS. ”

Tens of billions of dollars a year? Can it reach an annual output value of hundreds of billions of dollars in 10 years? A group of leaders didn't even know what to say, and finally Lin Zheng said that this conclusion came from the RAND think tank, but they simply ignored it, anyway, this money has nothing to do with the public security system.

"Ahem......" The deputy director who had just asked this question coughed embarrassedly twice, and hurriedly changed the topic: "Mr. Lin." Since you use the Americans' GPS satellite positioning system, you can still sell these drones to the United States, have you ever thought about exploring the American market? ”

"To tell you the truth, we really have this plan," Lin Zheng was reluctant to continue on this topic, and immediately said: "We plan to go to Europe and the United States in the next step, sell our drone products to Europeans and Americans, and export to earn foreign exchange." ”

"Can they say yes?" Lin Zheng, who was naturally happy with the other deputy directors, diverted the topic and asked: "If drones are used, what will happen to their original police helicopter pilots?" Aren't Americans taking employment issues very seriously? "To be continued.
