Parabolic force at high altitude

1.

The calculation formula of falling objects can be expressed by gravity formula. The gravity of objects at the same point on the ground is directly proportional to the mass m of objects. Similarly, when m is fixed, the gravity of objects is directly proportional to the acceleration g of gravity

was expressed by the formula g = mg. Generally, near the surface of the earth, the value of G is about 9.8n/kg, which means that the gravity of an object with a mass of 1kg is 9.8N

8N was an average value; On the equator, G is the smallest, g = 9.79n/kg; At the two poles, G is the largest, g = 9.83n/kg. N is the unit of force, the letter is n, 1n is about the force to pick up two eggs

1. The acceleration of an object is one of the important factors determining the magnitude and direction of gravity. The acceleration is closely related to the reference frame, so the most convenient method to study gravity can be obtained by choosing the appropriate reference frame. If the reference frame is not selected properly, sometimes wrong conclusions will appear

(this is quite different from the actual forces such as gravitation, elastic force and friction force. The magnitude and direction of these forces are not directly related to the acceleration of the object, so the selection of reference frame does not change the difficulty of their research.) in this definition, the support or the object itself is selected as a non inertial frame

Gravity is the resultant force of gravitation and inertial force, or a component of gravitation, and the resultant force resulting from the combination of forces or the component resulting from the decomposition of forces are all forces imagined by human beings. So gravity is a virtual force

In physics, there is no essential difference between the earth, moon, Mars, man-made earth satellite and so on. According to the new definition (gravity is the resultant force of universal gravitation and inertial force on an object), the same object is placed on different celestial bodies, and the gravity on an object varies greatly

for example, the gravity of the same object on the moon is much smaller than that on the earth, and if you put it on a satellite, the gravity will be zero (completely weightless, in fact, it's just the gravity of the satellite on the object and its tiny)

4. The gravity of the same object will change greatly e to the change of acceleration

2. Although the state has repeatedly stressed the drawbacks of throwing objects at high altitude, and listed the illegal acts and punishment in the civil law, throwing objects at high altitude is still common, and its root is that the source can not be traced, so the offenders are unscrupulous
with the breakthrough of artificial intelligence technology in computing power and algorithm, jialianbao has developed a high-altitude parabolic AI intelligent monitoring solution to solve this problem, which is specially designed for high-altitude parabolic monitoring in the community, and uses AI technology to detect the high-altitude throwing behavior in the community, so as to prevent the occurrence
Jia Lian Bao AI surveillance cameras are deployed around the community to cover the balcony area of the building from bottom to top. When there are falling objects, the intelligent analysis algorithm can quickly detect and alarm. At the same time, it is convenient for the backstage to find the real-time police situation and trace the source, and help the public security personnel to find the relevant responsible person, and then investigate their responsibility
even AI intelligent analysis can detect and analyze people's behavior, identify the behavior of throwing objects at high altitude in advance, and link with sound and light to prevent dangerous behavior in advance
in addition, e to the complex environment of the balcony, the false alarm rate of intelligent monitoring is high. Therefore, Jia Lian Bao AI intelligent monitoring carries out anti-interference training for AI intelligent video analysis function through algorithm learning library, so as to realize accurate recognition of target behavior in complex scenes
in terms of surveillance camera deployment and installation, according to the location, floor, orientation, spacing and other conditions of residential buildings, the integrated deployment and installation of high-altitude parabolic surveillance camera can cover the balcony of the surveillance floor and provide data source for AI behavior detection
in addition, Jia Lian Bao's AI intelligent monitoring system for high-altitude parabola includes the public road area where high-altitude parabola is most likely to occur in the community into the scheme of high-altitude parabola monitoring system, forming a complete evidence chain of high-altitude parabola before, ring and after the event
compared with traditional monitoring, Jia Lian Bao AI high altitude parabolic monitoring solution overcomes the technical shortcomings of traditional monitors, especially the problem of poor traceability effect
highlights of the scheme
Jia Lian Bao's AI intelligent monitoring solution for high-altitude parabolic not only covers the balcony of all floors of the community as far as possible, accurately identifies the behavior of high-altitude parabolic, achieves early warning and has laws to follow, so as to effectively avoid the occurrence of high-altitude parabolic behavior

in addition to monitoring high-altitude parabolic behavior, other pain points existing in the community can be effectively solved through jialianbao AI intelligent monitoring scheme, such as lake surface defense in the perimeter, community crowd gathering, garbage sorting, illegal parking, human like wall climbing, burglary, etc., so as to help the property to improve the management level and service ability, and provide residents with all-round safety and security services Smart community living environment.

3. Put the monitor up on the ground, monitor so that you can see the high-altitude parabola

We know that the property management department is responsible for the safety and sanitation of the community. Because of the particularity of falling objects, it is difficult for us to find the real responsible person. If the property enterprise can prove that the damage is caused by the victim intentionally, it will not bear civil liability. If it can not prove, it will bear civil liability

because the property management is obliged to manage the high-rise buildings, in order to avoid such incidents, the property management or the merchant management should inspect the hidden dangers of the high-rise buildings regularly and repair the problems in time

However, it is not enough to rely on the property company alone. The owners of residential areas should also be vigilant and check their own facilities regularly. The owners should not throw objects at high altitude, regularly maintain the things placed outside their high buildings, and regularly inspect the property. I think there will be very few high-altitude hazards
