Problems solved by technology

However, shooting through the camera can only be used to trace back the case after the danger occurs and help find the parabolic person, but cannot provide timely safety warning when the danger occurs; moreover, there are many restrictions through the camera, and the use effect is relatively poor in rain, snow, fog and other weather. Poor; in addition, modern people are more concerned about privacy protection, installing too many cameras around high-rise buildings will easily leak people's privacy and affect people's normal life

Embodiment 1

[0060] An embodiment of the present invention, such as figure 1 As shown, the present invention provides a kind of high-altitude parabolic early warning method, comprising steps:

[0061] S1. Real-time monitoring of the sky above the sides of high-rise buildings through 3D millimeter-wave radar.

[0062] Specifically, the 3D millimeter-wave radar is installed on the floor or side of the high-rise building, and at least one 3D millimeter-wave radar is installed on each floor. Install a 3D millimeter-wave radar. When installed, the monitoring direction of the 3D millimeter-wave radar is the vertical direction.

[0063] S2. When a falling object appears within the monitoring range, calculate the falling speed of the object in real time.

[0064] 3D millimeter-wave radar is a radar that works in the millimeter-wave band for detection. The wavelength of millimeter-wave is between microwave and centimeter-wave. Therefore, millimeter-wave radar has some advantages of microwave rada...

Embodiment 2

[0071] An embodiment of the present invention, on the basis of Embodiment 1, after calculating the falling speed of the object in real time, further includes: if the falling speed of the object exceeds the second preset speed, an alarm is given, and the second preset speed is greater than the first preset speed speed.

[0072] The falling speed of an object is directly related to its volume, weight, and height. Therefore, if the initial falling speed of an object within the monitoring range of the 3D millimeter-wave radar reaches the second preset speed, it means that the falling speed of the object will be faster afterwards. Therefore, in order to ensure the timeliness of early warning, it is necessary to directly report to the police.

[0073] Specifically, the magnitude of the second preset speed is not fixed, and the second preset speed is greater than the first preset speed. When the falling speed of the object reaches the second preset speed, it means that the object can...

Embodiment 3

[0081] An embodiment of the present invention, on the basis of Embodiment 1 or 2, after real-time monitoring of the sky above the side of the tall building through 3D millimeter-wave radar, further includes the step of: storing the whereabouts information of the current object in real time; if the current object does not trigger an alarm, Then the stored whereabouts information corresponding to the current object is automatically deleted.

[0082] After the alarm is given, further steps are included: simulating the movement path of the current object according to the whereabouts information of the current object; obtaining the movement starting point of the current object according to the movement path.

[0083] While the 3D millimeter-wave radar is monitoring, it can store the whereabouts information of each object in real time, and when the current object does not trigger an alarm, it can automatically delete the stored whereabouts information corresponding to the object, so ...

Abstract

The invention provides a high-altitude parabolic early warning method and system. The high-altitude parabolic early warning method comprises the following steps of monitoring the side sky of a high-rise in real time through a 3D millimeter-wave radar, when a falling object appears in the monitoring range, calculating the falling speed of the object in real time, when the falling speed of the object exceeds a first preset speed, calculating the volume of the object, and when the volume of the object exceeds the preset volume, giving an alarm. The scheme is not influenced by weather, does not leak privacy of people, can timely give an early warning when danger occurs, and is beneficial to protecting life and property safety of people.

Description

technical field [0001] The invention relates to the technical field of safety early warning, in particular to a high-altitude parabolic early warning method and system. Background technique [0002] With the advancement of modernization, high-rise buildings have sprung up in every corner of the city. While high-rise buildings are convenient for people's lives, they also bring the danger of high-altitude parabolic objects. High-altitude parabolic objects are extremely concealed and dangerous, and high-altitude parabolic incidents have been repeatedly banned, which has greatly endangered people's lives and property. [0003] The existing methods against high-altitude parabolic objects are mainly ideological and moral propaganda, harmful publicity, and the positioning and accountability of high-altitude parabolic persons through cameras. However, shooting through the camera can only be used to trace back the case after the danger occurs and help find the parabolic person, but ...
