"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 associated with drones.

Finally, if the drone has an accident during the flight, of course, this probability is very low. Our drone is driven by a four-axis propeller, and 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 up a deceleration parachute bag on top of the drone, which can be thrown in 0.5 seconds and then quickly opened to reduce the drone's landing speed. And during the landing, the drone will also flash warning lights and sounds to remind people and vehicles in the landing area to avoid.

I would like to emphasize that these security measures are rigorously tested, and we only allow them to be tested for practical applications after we are sure that they are 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.

The screen on the other side has replaced some surveillance screens. This is exactly the monitoring screen of the community unmanned intelligent express delivery collection and delivery point at this point, as well as the monitoring screen on the unmanned vehicle equipped at this point.

By monitoring Jiang Nan, they saw that this so-called community unmanned intelligent express delivery point is somewhat like a sentry box or a separate newspaper kiosk, which belongs to an independent building.

The roof of the building is a take-off and landing field for drones, where incoming drones will land to load and unload goods, or carry out temporary charging.

There is a glass window below the community unmanned intelligent express delivery collection and delivery point, and there is a screen in front of the window, where people can pick up the goods independently by entering the pickup code or scanning the code with their mobile phones.

Of course, door-to-door delivery can also be carried out by the unmanned vehicles equipped with the unmanned intelligent express delivery collection and delivery points in this community.

"You can see the radial lines at this point, which is the working path of the unmanned vehicle equipped with this point. Compared with drones, unmanned vehicles are quieter, safer, and more flexible. Not only does it drive into densely populated areas, but it also shuttles through floors and small spaces.

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

Jiang Nan nodded when he heard this, and then asked Lin Jiaming: "In the community, will the frequent take-off and landing of this drone have an impact on residents, especially in terms of noise." ”

Hehehehe...... Hearing this question, Lin Jiaming and Wu Hao both laughed. I saw him smile and shake his head at the meeting and said, "No, we have already considered this aspect a long time ago." You can see so many unmanned smart delivery collection and delivery points in the community on the map, and so far we have not received any complaints about drones disturbing people.

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

Therefore, our drones will take off and land in this relatively gentle way, so the sound will be quieter.

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

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

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

On the other hand, we have optimized the propeller blades to make them have more lift and less noise during rotation.

Generally speaking, as long as people are separated by a certain distance, it is basically impossible to hear, and even if it is operated all day, there is no problem. What's more, we strictly follow the relevant schedule regulations, and stop operating before 7 am and after 7 pm. We minimise our impact and have as little impact on the population as possible. ”

Hearing Lin Jiaming's explanation, Jiang Nan couldn't help but nodded. Then I stared at the picture on the big screen.

Soon, she raised a new question: "This intelligent regional unmanned delivery system can only realize the logistics express transportation work in the region, so how to carry out cross-regional." ”

Hearing this question, Lin Jiaming looked at Wu Hao, Wu Hao nodded when he heard this, and then smiled at Jiang Nan and introduced: "You can regard this intelligent regional unmanned delivery system as a chess piece, and the entire city or entire region as a chessboard."

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

This is what we call a modular unit, where each piece operates independently, but can be combined with other modular units to form a whole.

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

This system can connect all the module units, that is, the intelligent regional unmanned delivery system that we distribute in various areas, to form a whole. Drones or unmanned vehicles, or even manned freight vehicles are then used to transfer between modular units.

Of course, logistics goods transported from outside the region can also be transferred through this system until they reach the recipient, and conversely, the sender's parcel goods can also be transferred out of the region through this system.

We can even see this city or this region as a chess piece or a modular unit, and the whole country and even the world as a chessboard. Then we can realize the transfer of goods at this level, and accurately transfer the goods to the target location.

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

If this system can be realized, we can shorten the express logistics transportation time of more than 80% of the domestic regions from three days to one day, or even less.

The resulting economic benefits will be hundreds of billions of trillions. Moreover, this is not only reflected in the economic benefits, but also in the social benefits, and many other aspects that are closely related to our lives will change, so to speak, bringing our human society into a new stage of development. ”
