The radar device 211 is configured to acquire coordinate information of a falling object falling within a monitoring range of the processor, and transmit the coordinate information of the falling object to the floor processor 100 of a floor where the processor is located.

The overall controller 400 processes the coordinates under the overall coordinate system 600 and predicts the trajectory of the falling object. The overall controller 400 selects the floor protection module 220 according to the predicted running track and controls the protection net motor 221 to work. The protection net motor 221 drives the protection net 222 to open.
The embodiment also comprises a monitoring module. The monitoring module includes a plurality of monitoring cameras 300. As shown in fig. 4, a monitoring camera 300 is provided for each floor. The monitoring camera 300 is electrically connected to the floor processor 100. After predicting the motion track of the falling object, the master controller 400 sends coordinate instructions to each floor processor 100, and the floor processors 100 adjust the angle of the monitoring camera 300 according to the obtained coordinate instructions, so that the monitoring video information of the motion track of the falling object is obtained.

However, in other embodiments, the coordinate system 600 of the present embodiment may not be limited, and other suitable coordinate systems 600 may be selected as the reference coordinate system.
The present embodiment also includes a number of guards 200. As shown in fig. 6 and 7, the guard device 200 includes a fixing plate 230 for fixed connection with a balcony. The radar device 211 is rotatably connected to the fixing plate 230. The protection net 222 is rotatably connected with the fixing plate 230. The street lamp also comprises a falling object prompting street lamp 500 arranged on the sidewalk. The master controller 400 is electrically connected with the falling object prompting street lamp 500 and controls work. In this embodiment, the protective net 222 is a soft and flexible woven net, which can reduce the possibility of the falling object bouncing.
Specifically, when the above-described description of the features is applied to floors, as shown in fig. 4 and 5, the falling object is captured by the radar device 211 on the balcony of 1601 household from the floor of 16 floor, and transmits the coordinate information and the time node to the floor processor 100 of 16 floor; coordinate information and a time node are captured by the radar device 211 on the balcony of 1502 inhabitants among floors falling to the 15 th floor, and the coordinate information and the time node are transmitted to the floor processor 100 of the 15 th floor; and then falls to the floor of the 14 th building, is captured by the radar device 211 on the balcony of the 1402 family to acquire coordinate information and a time node, and transfers the coordinate information and the time node to the floor processor 100 of the 14 th building. The floor processor 100 of the 16 th floor converts the acquired coordinate information into a coordinate under a total coordinate system 600, namely a first falling object coordinate; the floor processor 100 of the 15 th floor converts the acquired coordinate information into a coordinate under a total coordinate system 600, namely a second falling object coordinate; the floor processor 100 of building 14 converts the acquired coordinate information into coordinates under the overall coordinate system 600, i.e., the coordinates of the third falling object.

The second embodiment:
the embodiment discloses a high-altitude falling object prevention method, which is suitable for the high-altitude falling object prevention method in the first embodiment, and as shown in the attached figure 8, the method comprises the following steps:
step S100: the master controller 400 acquires three reference position information of the three floors which are successively approached by the falling object in the falling process. The reference position information includes drop coordinates and time nodes.
In this step, the total controller 400 acquires the three reference position information through the following steps.
The falling object falls into the monitoring range of one radar device 211 of one floor, the radar device 211 transmits the monitored coordinate information of the falling object to the floor processor 100 of the current floor, the floor processor 100 of the current floor converts the coordinate information of the falling object into reference position information under the total coordinate system 600, and transmits the reference position information to the total controller 400. The three pieces of reference position information obtained in this step are pieces of reference position information of three floors through which falling objects successively pass, that is, as shown in fig. 4 and fig. 5, when falling objects successively pass 16 th, 15 th and 14 th, the radar devices 211 of 16 th, the radar devices 211 of 15 th and the radar devices 211 of 14 th capture coordinate information of falling objects respectively, and transmit the respective coordinate information to the floor processor 100, the floor processor 100 converts the coordinate information into a first falling object coordinate (measured by 16 th), a second falling object coordinate (measured by 15 th) and a third falling object coordinate (measured by 14 th) under the total coordinate system 600, and meanwhile, each floor processor 100 also transmits time nodes when the falling object coordinate information is captured to the total controller 400 together.
Step S200: the overall controller 400 processes the three reference position information and predicts the motion track of the falling object.
In this step, the master controller 400 calculates the distance difference between the coordinate axes of two adjacent falling objects and the time difference between two adjacent time nodes, and obtains the motion trajectory of the falling object in each coordinate axis direction according to the distance difference between the two sets of coordinate axes and the two sets of time difference. That is, the total controller 400 calculates a distance difference in the X-axis direction, a distance difference in the Y-axis direction, and a distance difference in the Z-axis direction between the first falling object coordinate and the second falling object coordinate, and calculates a distance difference in the X-axis direction, a distance difference in the Y-axis direction, and a distance difference in the Z-axis direction between the second falling object coordinate and the third falling object coordinate. Through the distance difference between the first falling object coordinate and the second falling object coordinate in the X-axis direction and the time difference between the two time nodes, the master controller 400 calculates the speed and the acceleration of the falling object movement in the X-axis direction. Similarly, the master controller 400 calculates the speed and acceleration of the falling object movement in the Y-axis direction and the Z-axis direction. The general controller 400 can obtain the next running approximate track of the falling object through the calculated speed and acceleration of the falling object in the X-axis direction, the Y-axis direction and the Z-axis direction.
Step S300: the master controller 400 judges the balcony through which the falling object passes next according to the predicted falling object movement track, and controls the protective net motor 221 and the protective net 222 on the balcony to be passed to start working.
Since it takes time to open the protection net 222, calculation is required for balcony position selection that can fully open the protection net 222 between the arrivals of falling objects.
The method specifically comprises the following substeps:
step S310: the total controller 400 processes the predicted trajectory results in the Z-axis direction of the coordinates of the three falling objects, and calculates the floor when the protection net 222 of a certain floor is completely opened when the falling object just falls to the balcony position of the floor, and then the process proceeds to step S320.
If the calculation result indicates that the falling object passes through each floor and the guard nets 222 of each floor are not fully opened, the process proceeds to step S340.
In this step, the balcony position where the falling object can be caught is predicted from the speed and acceleration in the Z-axis direction, that is, the balcony position where the falling object can catch up with the falling speed is calculated, and when the falling object passes through the balcony, the protection net 222 on the balcony can be opened in time. The Z-axis is perpendicular to the ground and parallel to the building's coordinate axis.
Step S320: the total controller 400 processes the predicted trajectory results of the Y-axis directions of the coordinates of the three falling objects and determines whether the distance from the Y-axis direction of the falling object to the balcony is greater than the length of the protection net 222 when the falling object just falls to the floor where the protection net 222 has been fully opened.
When the determination result is yes, the process proceeds to step S340.
If the determination result is no, the process proceeds to step S330.
It should be understood that the length of the protection net 222 is a limited value, and when the falling object excessively moves away from the balcony, the falling object cannot be caught regardless of whether the protection net 222 is completely opened. The Y-axis is a coordinate axis direction parallel to the ground and perpendicular to the building.
Step S330: the total controller 400 processes the predicted trajectory results of the three falling object coordinates in the X-axis direction, and calculates the X-axis coordinate of the falling object when the falling object just falls to the floor where the protection net 222 has been fully opened, and the total controller 400 selects to open the protection net 222 appropriate for the current floor according to the X-axis coordinate of the falling object. In this step, when the master controller 400 selects that the protection net 222 can be fully opened and the distance from the falling object to the protection net 222 does not exceed the length of the protection net 222, the master controller 400 selects a suitable balcony position on the same floor, where the suitable balcony position is obtained by calculating the movement trajectory in the X-axis direction. The X-axis is parallel to the ground and parallel to the building's coordinate axis direction.
Step S340: the master controller 400 controls the falling object prompting street lamp 500 to light. The luminous falling object prompting street lamp 500 is used for prompting a passerby that a falling object exists at high altitude, and the falling object cannot be prevented from falling to the ground at present.
The above-described embodiments of the guard device 200 with the radar device 211 are installed at the balcony of a whole building in the present embodiment, and it should be understood that the guard device 200 may be installed at other positions of floors in other embodiments due to the actual construction of the building.
The embodiment can avoid the trouble that each house is provided with the protective net 222 with fixed appearance, which is easily blown and overturned by wind and rain. According to the embodiment, the position information of falling objects at high altitude can be captured in time, the motion track of the falling objects can be predicted in time, the protective net 222 at the most appropriate position is selected according to the track, the falling objects can be received by the opened protective net 222, and therefore the falling objects are prevented from falling onto the sidewalk, and the potential danger that passersby walking on the sidewalk are hit by the falling objects is reduced. In addition, the embodiment can control the monitoring cameras 300 of all floors to adjust the shooting angle in time after capturing the position information of the falling object and predicting the motion track, record the falling path of the falling object, and facilitate the calling of video files to find responsibility when an accident occurs.
The above embodiment is applied to floor residents, only the protection device 200 needs to be installed at a home balcony position, the protection device 200 has the advantages of simple structure and low cost, and the protection net 222 can be folded without affecting the appearance of the floor when no object falls.
The embodiment can also open the falling object prompting street lamp 500 on the sidewalk in time when the master controller 400 judges that the protective device 200 on the whole floor can not prevent falling objects from falling according to the predicted track, so as to prompt pedestrians to fall objects carefully.
In the embodiment, the trajectory prediction is performed by selecting the three reference position information captured when the falling object successively passes through the three floors, the three floors have a certain distance difference, the trajectory of the falling object is basically formed at the moment, and compared with the problem that the subsequent path is greatly influenced by uncontrollable factors due to the fact that a plurality of coordinates are measured at the same position to predict the trajectory of the falling object, the prediction result of the embodiment is slightly influenced by the uncontrollable factors, and the actual trajectory of the embodiment basically accords with the predicted trajectory predicted according to the speed and the acceleration of each coordinate except extreme weather or extreme external factors. Therefore, the method has the characteristics of simple track prediction mode and strong practicability.
