【Chapter 292】The earth can't stop it

Su Wenruo silently followed Staff Officer Jiang and sat down in the back row, picked the palm of his left hand with his right hand, and cut it into the flesh.

Qin Jianglan said on the stage: "I'm already on stage, so I'll start first, Yu Lin, don't you have any opinions?" ”

There was a very soft laugh from the audience, which was about the presence of a big leader, and these comrades did not dare to laugh out loud.

Whether it is a competition, or a performance program, or any occasion, no one will like to be the first to go on stage, especially the scene to be scored, the person who goes on stage first must suffer from the person behind, because the judges will not score too high in front, and they are afraid that the person in the back will be better than the person in front, and the score in front will reach the top, which will make the person behind unable to score.

Qin Jianglan ran to the stage first, and he was afraid that Yu Lin would be unhappy when he suffered a loss, obviously adjusting the somewhat tense atmosphere at the scene.

Yu Lin, who was sitting in the front row, shook his head with a smile and said that he had no opinion.

Qin Jianglan pressed the remote control in his hand, and the big screen behind him lit up: "Before I start explaining my design, I want to take you to review the various out-of-control moments at the fire scene." ”

Those pictures are the real disaster situation taken by various surveillance cameras, all of which are emergency and dangerous disaster scenes, such as sudden explosions of high-rise buildings in cities that are too late to extinguish after they catch fire, various chemical accidents, ordinary houses in the countryside that lack the necessary fire-fighting facilities to burn down and collapse, wild mountains and forests burned down in large areas due to wind-supported combustion, and so on.

Qin Jianglan pressed the remote control in his hand, froze and switched the big screen behind him, and then froze and switched, and asked: "The city is densely populated with high-rise buildings, and there are many cases in the building that cause fires and explosions due to the storage of flammable and explosive materials, and chemical accidents are always in the nick of time, what should people do if they don't have time to escape?"

What should I do if people are buried in the simple structure of ordinary houses in the countryside and the fire rescue is far away, so when the house collapses?

As long as there is a little spark in the wild mountains and forests, the wind blows much faster than the rescue speed of firefighters, what should I do?

At this time, it was all firefighters who rushed in regardless of the danger to their lives. ”

This is also a concern of the leaders of the public security sector, but these problems have always been in the problem stage, and there is no practical solution.

The disaster in these pictures happened too suddenly, and by the time people reacted, they might have been trapped at the disaster site, or even lost their lives.

At such a time, there are always firefighters who are not afraid of death, knowing that they will never return to such an urgent and dangerous fire scene, and knowing that there may be no surviving lives inside, they still rush in without hesitation, and therefore pay the sacrifice that can be foreseen but have to go.

Qin Jianglan switched the screen again, and a seemingly small partner appeared on the big screen behind him, he pointed to the big screen and said: "I believe everyone is no stranger to this thing, that's right, it's a drone." ”

The leaders looked at each other, and no one spoke, but the eyes of those people were unapprehensive and uncertain.

Drones have also been tried to be used for fire rescue in China, but in fact, this thing has no practical use.

In addition to being able to fly into the fire scene, throw some light rescue materials with loads, and shoot pictures of the scene, it is not helpful to extinguish the fire at the entire scene.

Because of the battery limitation of the drone, it will not be able to fly for long at all, and with the weight of the load, ten minutes is already the limit.

It is precisely because of the huge consumption of UAVs in terms of scientific research and technology, the projects involved, and the financial problems required, which cannot be classified as widely used, and are still in the trial stage.

Qin Jianglan obviously knew that the people in the audience would have doubts about the drone he displayed on the big screen, so he took out a notebook from his handbag, turned on the software after turning it on, and then flew in from the side door of the conference hall that had never been closed.

In appearance, this drone is no different from other drones, except for the tank containing a round mobile sprayer with a kilogram on its belly.

The red little friend flew in the middle of the air in the conference hall, and after turning around the hall, the people sitting on the chairs felt that the air was suddenly a little cold, and they looked at the central air conditioning on the ceiling one by one.

Qin Jianglan was still playing with his notebook on stage, and the red drone had already flown above his head, staying in the air and not leaving.

He raised his eyes and looked at the audience and said: "I believe that many comrades are now playing question marks in their hearts, Qin Jianglan is thinking that there is too much electricity, let the drone discharge above his head, just sit and watch the show, see how long you can put it, haha, be honest, people who have this kind of thought, raise your hand!" ”

As a result, all the hands of the people below were raised.

Qin Jianglan nodded and said with a smile: "My next explanation and demonstration operation will take about sixty minutes, and the time that this drone above my head stays in the air can stay longer than the time I explained, as for how long it can stay in the air today, everyone present can witness it with their own eyes, so everyone can ignore it now and let it play by itself." ”

This is very unexpected, you know, the drone in the case of load, the battery consumption is very large, this fiery drone, there is still a kilogram of mobile sprayer on the belly.

A kilogram also has weight, it is unimaginable, China can now produce such a large capacity, but the volume is so petite battery, if such a technology is used in automobiles, foreign countries have to go crazy to squeeze into China?

Qin Jianglan's voice sounded again: "Let me first talk about what this drone can do, in the emergency and dangerous disaster sites that you saw just now, the previous drones were not comprehensive because of the limitations of battery technology, and they couldn't even talk about extinguishing fires."

But Xiaohong, forehead...... The one I play alone above my head is Xiaohong, who can ignore the terrain and environment, go straight to places that are inaccessible to firefighters, and the high-definition camera is flexible and mobile to detect the scene.

The high-suppression heat source sensor can accurately and intuitively analyze the overall fire data, and the anti-jamming amplification module can realize air shouting and convey instructions.

In the event of an earthquake or wildfire in some areas, Xiaohong can act as a temporary relay station in an environment where communication is blocked, and in extreme environments, wireless communication can still be established to ensure that the disaster is understood at the first time

A mobile sprayer carried on her stomach can be used to extinguish fires, in short, Xiaohong can fly to places that people can't reach instead of firefighters, helping to eliminate danger. ”

It sounds very good, the leaders in the audience smiled and exchanged their heads for a while, probably saying that Qin Jianglan probably forgot that the drone can't fly for long, and the battery is the biggest hard injury, otherwise there is no need to always let firefighters take risks with their bodies.

If the battery is excluded, a factor that cannot be changed for the time being, drones can indeed do things that cannot be done by humans in the fire.

Firefighting is a high-risk field, and the use of the omnipotent drone in Qin Jianglan's mouth to replace part of the manpower action is self-evident for firefighters.

First of all, the UAV medium and low altitude monitoring system has the ability to quickly and real-time patrol and monitor the terrain environment, and can accurately grasp and timely understand the remote areas that cannot be taken into account by ground patrols, in the early detection of mountain fires, and various dynamic information at the scene of major forest fires.

It can also solve the problems of helicopter patrol unable to fly at night when a wildfire occurs, and the visibility is too low due to smoke to fly.

Now, if it is really as good as Qin Jianglan said, it will be used as a powerful supplement to forestry monitoring methods, and has its unique advantages in resource and environmental monitoring of areas that cannot be reached by vehicles and people, forest fire monitoring and rescue command.

The premise is, whether "Little Red" can really fly for that long!

The eyes of the people in the audience began to look at the top of Qin Jianglan's head one by one, and Xiaohong still stayed in the air.

Qin Jianglan smiled: "It seems that everyone is concerned about when Xiaohong will fall from the top of my head." ”

The people below couldn't help but cover their mouths and snicker.

Qin Jianglan Zhengse said: "Let me first introduce the structure of Xiaohong, the fuselage is all made of new high-strength carbon fiber materials, carbon fiber is soft on the outside and rigid on the inside, the weight is lighter than that of metal aluminum, but the strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus."

Comes with a safe and fireproof power system, digital PTZ combined with GPS, accurate positioning of the fire point, computer control point where to fly, don't worry about not learning not to use the background, Xiaohong has a fool-like operation, one-button recycling, clear camera, wireless digital transmission, its own mobile sprayer, can be used in a wide range of urban commercial buildings, residential areas and forest areas for fire reconnaissance and rapid fire extinguishing. ”

When they arrived here, everyone was about to listen to the most important energy consumption problem, but Qin Jianglan paused, raised the corners of his mouth and pointed at Xiaohong above his head and said, "Do you know how cold I am now?" ”

Obviously, this question cannot be answered below, but this cold feeling, the people in the conference hall just now seem to have felt it, guessing that the central air conditioning of the ceiling is being tested.

Qin Jianglan was naughty just now and said that he was very cold, but the voice that came from him in the blink of an eye immediately became sonorous and powerful: "The drone Xiaohong above my head has a maximum wind resistance of eight levels, a maximum load of twenty kilograms, a maximum cruising speed of 30m/s, and a maximum endurance of five hours. Thank you! ”

The audience "buzzed", and even the leaders in the front row couldn't sit still, and looked at the people next to them with wide eyes in disbelief, wanting to ask if they had heard it wrong just now?

This drone does not need batteries, it can cruise with only the strong cold dry fog of a mobile sprayer, with a maximum load of twenty kilograms, that is, a larger mobile sprayer can be installed on the fuselage to push, which solves this problem, and what else can stop it from saving lives and property on Earth!
