Urban safety monitoring and early warning system and method based on high-resolution satellites

Abstract

The invention provides an urban safety monitoring and early warning system based on high-resolution satellites. The urban safety monitoring and early warning system comprises a cross-shaped referenceframe, a horizontal rod, a bottom shell, a constant ball, a light gathering cover, a top shell, a circuit box and screws. The cross-shaped reference frame is installed on the wall of a building through screws, the horizontal rod horizontally extends out of the center of the cross-shaped reference frame, the hemispherical-shell-shaped bottom shell with an opening in the top is arranged at the outerend of the horizontal rod, a plurality of photosensitive elements are evenly distributed on a transparent layer on the inner layer of the bottom shell longitudinally and transversely, and a shading layer is arranged on the outer layer of the bottom shell. The top shell is a hemispherical shell with an opening at the bottom, a transparent area is arranged at the top of the top shell, the top shelland the bottom shell form a complete spherical shell, the spherical constant ball with a planar top is installed in the shell, lubricating oil is coated between the constant ball, the bottom shell, and the top shell; and the gravity center of the constant ball is concentrated at the bottom end; a light guide hole with a mirror surface on the inner wall penetrates through the central axis of the constant ball, and the light gathering cover is arranged at a top opening of the light guide hole; the circuit box is screwed on the cross-shaped reference frame, and a light detection and communication circuit and a processor are arranged in the circuit box.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a high-resolution satellite-based urban safety monitoring and early warning system. Background technique [0002] On December 10, 2019, the National Space Administration released the first batch of 22 sub-meter stereoscopic image products of the Gaofen-7 satellite. This is not only the first appearance of Gaofen-7, but also marks that the construction focus of my country's high-resolution Earth observation system major project (referred to as the Gaofen Project) will shift to the application stage. From Gaofen No. 1 to Gaofen No. 7, the scale of the "Gaofen Family" has continued to grow, and their abilities have become stronger and stronger. At present, my country has successfully launched Gaofen-1 high-resolution wide-format, Gaofen-2 sub-meter panchromatic, Gaofen-3 1-meter radar, Gaofen-4 synchronous staring, Gaofen-5 hyperspectral observation, Gaofen-6 7 civilian high-resolution satell...

Problems solved by technology

However, since the current number of high-resolution satellites is far from being sufficient for on-site monitoring of all urban buildings, it is necessary to analyze the image data of urban buildings from high-resolution satellites, in the areas of suspected sloping buildings or areas prone to surface subsidence. On the building, the monitoring device is arranged to monitor the tilt of the building on the spot, forming a comprehensive monitoring system integrating heaven and earth
