There will be no pies in sky, but something else.
Big dog from the sky
A plank falling from sky
You never know what will happen next.
On June 13, in Futian Township, Shenzhen Province, a window that fell from 20th floor hit a boy. After several days of rescue work, boy died from his injuries.
On June 17, a passer-by in Heze Township, Shandong Province, was injured and fell to ground when an aluminum alloy window fell from 19th floor. Fortunately, his life was not in danger.
On June 18, a little girl from Nanchang, Jiangxi Province, was doing her homework in front of a store when a falling object hit her on head, causing her to bleed.
June 19, a 10-year-old girl who was finishing school in Nanjing, Jiangsu Province, was hit in head by a high-altitude parabolic object and is currently being treated at a hospital.
Looking at parabola incident at high altitude, nothing but grief is anger. Don't these people know about danger of falling objects?An object falling from a height, even an egg can kill a person
A 30-gram egg thrown from 4th floor will make people swell up;
If you throw it from 8th floor, you can break scalp;
You can break skull by throwing it from 18th floor;
A throw from 25th floor can instantly kill a person.
The key was thrown from a height of 30 meters, and an 8 mm thick glass plate instantly shattered in half.
The high-altitude parabolic is known as pain that hangs over city, it damages environment, easily causes fires, damages people's lives ... In a word, it is harmful, but there is no benefit.
However, there will always be people who want to make life easier for a while and put other people's lives at risk. Even if owner cannot be found, entire building will be legally liable and will become a defendant.
Aren't there good technical means to prevent such things from happening, and also to give a warning to those who are lucky?Safety technology fights falling objects
1. Install antiparabolic monitoring in public areas
Installing high-definition monitoring equipment in crowded public places not only has a warning effect, but when a high-altitude parabola occurs, system will capture and record trajectory of parabola, play through screen, quickly capture alarms and transmit images, which helps to quickly catch and train thrower in time.
For example, 47 high-altitude anti-parabolic cameras have been installed in Hangzhou. These wide-angle cameras can cover windows and balconies of entire building in shooting area. So far, no high-altitude parabolic incident has been reported.
2. Artificial Intelligence Technology Tracks Parabolic Community Behavior at High Altitude
With breakthrough of artificial intelligence technology in terms of computing power and algorithms, AI combined with surveillance camera design can realize full coverage of residential building balcony area from top to bottom. building's facade.
When there is a falling object, intelligent analysis algorithm can quickly detect and call police. At same time, it is convenient for background to detect real-time police situation and track source, helping public safety. personnel to find appropriate person in charge and then hold them accountable
Even AI intelligence can detect and analyze human behavior, predict target behavior to be parabolic at high altitude, and link sound and light reminders to prevent dangerous behavior from occurring in advance.
Refusal to drop (throw) objects from great heights! In addition to strengthening external governance and technical protection, it is more important to develop civilized behavior.
After two more steps, you won't get tired, but once you're thrown off the top floor, you'll never know how much irreparable damage you've caused to others.
Don't do to others what you don't want to do to others, don't throw things at high altitudes, start with me.
