"In addition, our drones are only responsible for point-to-point transportation, and they do not touch people, so they are isolated from the dangers brought by drones.

Finally, if the drone has an accident during the flight, of course the probability is very low. Our drone is driven by four-axis propellers. After losing the power of two propellers, it can still maintain a certain speed and land smoothly, and avoid the surrounding crowd.

Even if there is an accident in the air, the entire drone loses power. We set a deceleration parachute bag on the top of the drone, which can be thrown out within 0.5 seconds, and then quickly opened to slow down the drone's landing speed. And during the landing process, the drone will also flash warning lights and sounds to remind people and vehicles in the landing area to avoid.

What I want to emphasize is that these security measures have been strictly tested, and we put it into the actual application test after it is determined that it is safe enough. "

Speaking of this, Lin Jiaming tapped the keyboard again, and the picture on the big screen changed immediately. As he clicked on a point on the map, the point zoomed in, and some radial lines appeared around the point.

As for the screen on the other side, some monitoring screens have been replaced. This is exactly the monitoring screen of the community unmanned intelligent express delivery point at this point, as well as the monitoring screen on the unmanned vehicle equipped at this point.

Through monitoring Jiang Nan and the others, they saw that this so-called community unmanned intelligent express delivery point is a bit like a sentry box or a separate newsstand, belonging to an independent building.

The top of the building is the take-off and landing field for drones, where the flying drones will land to load and unload goods, or temporarily charge.

There is a glass window under the unmanned intelligent express delivery point in the community, and a screen in front of the window. People can pick up the goods independently by entering the pick-up code or scanning the code with their mobile phones.

Of course, door-to-door delivery services can also be provided by unmanned vehicles equipped with unmanned intelligent express delivery points in this community.

"You can see the radial lines on the door at this point, which is the working path of the unmanned vehicle equipped at this point. Compared with drones, unmanned vehicles are quieter, safer, and more flexible. It can not only Driving into crowded areas, it can also shuttle through various floors and small spaces.

Through this unmanned vehicle, we can deliver the goods to the door of the household, or pick up the goods at the door of the household. "

Jiang Nan nodded when he heard the words, and then asked Lin Jiaming: "In the community, will the frequent take-off and landing of such drones affect the residents, especially in terms of noise."

Hehehehe... Hearing this question, both Lin Jiaming and Wu Hao laughed. He smiled and shook his head towards the meeting and said: "No, we have already considered this aspect. You can see so many unmanned smart express delivery points in the community on the map, and we haven't accepted them yet. As for the complaints about drone nuisance.

In fact, the drone only produces loud noise when flying at high speed. When it is flying at low speed, the sound is very peaceful, only forty to fifty decibels, which is similar to the ambient sound on the street.

Therefore, our drones will use this relatively gentle method when taking off and landing, so the sound will be smaller.

Of course, this is also for take-off and landing safety.

Secondly, these community unmanned smart express delivery points are set up in relatively open and remote places, which basically will not affect everyone.

Finally, we optimized the design on the drone's four-axis motor and propeller blades. On the one hand, the speed of the motor is faster, the power is greater, and the motor runs more quietly.

On the other hand, we have optimized the design of the blades of the propeller to make it have greater lift and less noise when rotating.

Generally speaking, as long as people are separated by a certain distance, they can basically not hear it, even if it runs all day long, there is no problem. not to mention,

We strictly follow the relevant work and rest time regulations, and we will stop operating before seven in the morning and after seven in the evening. Minimize the impact we have brought, and do not affect the public as much as possible. "

Hearing Lin Jiaming's explanation, Jiang Nan nodded involuntarily. Then he stared at the picture on the big screen.

Soon, she raised a new question: "This intelligent regional unmanned delivery system can only realize logistics and express transportation within the region, so how to do it across regions."

Hearing this question, Lin Jiaming looked at Wu Hao. Wu Hao nodded, and then introduced to Jiang Nan with a smile: "You can regard this intelligent regional unmanned delivery system as a pawn. The whole city or the whole region is regarded as a chessboard.

And what we have to do is to fill the empty area of ​​​​the chessboard with such pieces, so that it covers all areas.

This is what we call a modular unit, each of which operates independently, but can cooperate with other modular units to form a whole.

This is the smart city unmanned logistics transfer system that overrides this set of intelligent regional unmanned delivery systems.

This system can connect all the modular units, that is, our intelligent regional unmanned delivery systems distributed in various regions, to form a whole. Then use drones or unmanned vehicles, or even manned freight vehicles for transfer between module units.

Of course, the logistics goods transported from outside the region can also be transferred through this system layer by layer until it is delivered to the recipient. Conversely, the sender's parcel goods can also be transferred out of the region through this system.

We can even regard this city or this area as a chess piece or modular unit, and the whole country or even the whole world as a chessboard. Then we can realize cargo transshipment at this level, and accurately transship the goods to the target location.

In fact, this is the current express logistics transportation system, but we have changed it to be intelligent, automated, and unmanned.

If this system can be implemented, we can shorten the delivery time of express logistics in more than 80% of the domestic regions from the current three days to one day, or even shorter.

The resulting economic benefits will be on the scale of hundreds of billions of trillions. Moreover, this is not only reflected in economic benefits, but also social benefits, and many other aspects closely related to our lives will change, which can be said to bring our human society into a new stage of development.
