Description

Technical Field

[0001] The present invention relates to the technical field of preventing objects from falling from high altitude in buildings, and more particularly to the technical field of a system for identifying and actively protecting objects from falling from high altitude in buildings and a method for using the system. Background Art

[0002] As urbanization accelerates and the density of high-rise buildings increases, incidents of falling objects from high altitudes are becoming more frequent. China's first- and second-tier cities report an average of over 10,000 reports of falling objects annually (for example, Shanghai recorded approximately 13,000 reports in 2022), of which approximately 30% originate from residential buildings and 20% from falling facade materials from commercial buildings. Falling objects from high altitudes pose a serious risk to the safety of the public and their property. Although more and more communities are installing high-altitude cameras to record and investigate the causes of falling objects, this measure is only effective during post-incident investigations and cannot provide timely protection and avoidance measures.

[0003] In order to prevent the hazards caused by falling objects in a timely and effective manner, it is of practical significance to design a building falling object identification and active protection system. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems and provide a system for identifying and actively protecting falling objects from high altitude buildings and a method for using the system.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The present invention provides a building high-altitude falling object identification and active protection system, including an acquisition module, a high-altitude falling object detection and identification module, a high-altitude falling object protection module, a warning system and an edge computing device;

[0007] The acquisition module monitors the high-altitude environment outside the building; the multi-source data collected in real time is transmitted to the high-altitude falling object detection and identification module, and the high-altitude falling object detection and identification module determines whether a high-altitude falling object has occurred based on the signals in the multi-source data; when it is confirmed to be a high-altitude falling object, an alarm is sent to the warning system in the falling area, and at the same time, the high-altitude falling object protection module is triggered to actively intercept the high-altitude falling object.

[0008] Specifically, the system consists of four parts: a data acquisition module, a high-altitude falling object detection and identification module, a high-altitude falling object protection module, and a warning system. The data acquisition module, which includes high-definition cameras, radars, and other data acquisition equipment, monitors the high-altitude environment outside the building. Real-time video and radar data are transmitted to the high-altitude falling object detection and identification module, which uses signals from multiple sources of data to determine whether a falling object has occurred. Once a falling object is confirmed, an alarm is sent to the warning system in the falling area, forcing people to leave and triggering a protection system to proactively intercept the falling object to prevent accidents.

[0009] In one embodiment, the acquisition module is a multi-source data acquisition device, which includes a high-definition camera and a radar. The high-definition camera and the radar are installed on the building corresponding to the high-altitude falling object protection module and at the bottom of the building. The high-definition camera and the radar are connected to the input signal of the edge computing device.

[0010] Specifically, if Figure 1 As shown, multi-source data collection equipment is not only available at the base of the building, but also at intervals on floors such as the 4th, 8th, and 12th. This allows for the shortest possible warning of falls at different floors. It is installed on the same floor as the active protection system.

[0011] In one embodiment, the falling object protection module includes a plurality of hard fall protection systems and a plurality of soft fall protection systems alternately installed on the facade of the building from top to bottom;

[0012] High-definition cameras and radars are connected to the input signals of edge computing devices;

[0013] The warning system, each hard fall prevention system, and each soft fall prevention system are all connected to the output signal of the edge computing device.

[0014] In one embodiment, the widths of the hard fall arrest system and the soft fall arrest system increase sequentially from top to bottom in the deployed state.

[0015] In one embodiment, the hard fall prevention system includes a first vertical frame fixed to the facade of the building, a hard protective layer hinged to the bottom edge of the first vertical frame, and multiple cables are arranged at intervals on the edge of the hard protective layer away from the hinged side. The other end of each cable is connected to the upper edge of the first vertical frame. The hard protective layer is made of steel wire rope.

[0016] In one embodiment, the soft fall prevention system includes a second vertical frame fixed to the facade of the building, a soft protective layer hinged to the bottom edge of the second vertical frame, and multiple second cables are arranged at intervals on the edge of the soft protective layer away from the hinged side, and the other end of each second cable is connected to the upper edge of the second vertical frame.

[0017] In one embodiment, the soft protective layer includes a mounting frame hinged to the bottom of the second vertical frame, an outer airbag is disposed on the mounting frame, and an inner airbag is disposed on the inner side of the outer airbag.

[0018] Specifically, the falling object protection module features both soft and hard protective layers, effectively mitigating impact forces and intercepting falling objects. These layers are arranged alternately on each floor. The width of the protective layers increases as the floor descends, ensuring that falling objects are intercepted before they hit the ground.

[0019] The soft and hard protective layers share the same skeleton structure, differing primarily in the composition of the arresting layer. The hard protective layer is woven from fine steel wire rope, which offers a certain degree of ductility, complementing the diamond-shaped skeleton structure. The soft protective layer is constructed as a double-layer airbag. When the fall arrest system receives a command, the skeleton deploys, rapidly releasing gas to fill the double-layer airbag. This double-layer airbag ensures that even if a sharp falling object pierces the outer airbag, the inner airbag still provides some cushioning while mitigating the impact. Therefore, even if the outer layer ruptures, the inner layer still retains its cushioning function.

[0020] Another aspect of the present invention provides a method for using a system for identifying and actively protecting against falling objects from a building, which method is used to install the above-mentioned system for identifying and actively protecting falling objects from a building, comprising the following steps:

[0021] S1. Installation of multi-source data acquisition equipment:

[0022] The installation location of the multi-source data acquisition equipment is selected based on the planar shape of the building structure, ensuring that multiple sets of acquisition equipment can cover the entire facade of the building structure and have a certain overlapping coverage area; the multi-source data acquisition equipment includes high-definition cameras and radars, and the multi-source data acquisition equipment is connected to the edge computing equipment to ensure timely and lossless signal transmission;

[0023] S2. Installation of falling object protection module:

[0024] Falling object protection modules are installed at fixed intervals based on the building's floor height. For example, a fall protection system is installed every four floors. The falling object protection modules communicate with edge computing devices to ensure they automatically activate upon receiving a signal. Simultaneously, alarms are installed on lower floors of the building and are also connected to the edge computing devices.

[0025] S3. Collection and identification of falling objects from high altitude:

[0026] When a falling object occurs in a monitored building, the real-time image from the high-definition camera and the radio echo signal from the radar are transmitted to the edge computing device. The edge computing device can locate and identify fast-moving objects in the video based on the artificial intelligence spatiotemporal feature fusion network. At the same time, an abnormal signal is generated in the radar reflection signal. Based on the above multi-source data, a comprehensive assessment is made to determine whether a falling object has occurred.

[0027] S4. Startup of the falling object protection module:

[0028] According to the dangerous falling area analyzed by the high-altitude falling object recognition system, an audio warning is immediately issued to drive people away from the dangerous area;

[0029] At the same time, based on the floor position and impact force at different heights obtained by identification, the high-altitude falling object protection module below the initial falling floor is immediately activated, and the tension of the protection net is dynamically adjusted according to the impact index to intercept high-altitude falling objects;

[0030] In one embodiment, a high-definition camera can determine the type of object falling from a high altitude (e.g., exterior wall tiles, flower pots, etc.) based on a high-altitude falling object detection and recognition module, and calculate the impact force of the falling object at different heights by combining the volume of the falling object calculated based on radar reflection signals on both sides of the building;

[0031] Based on the multi-source data analysis results of video signals and radar signals, the floor and falling location of falling objects from high altitude can be quickly determined, and a protection system activation strategy can be formulated.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. This patented system for identifying and actively protecting buildings from falling objects presents a collaborative technology combining multi-sensor fusion and real-time protection. This technology utilizes spatiotemporal feature fusion to dynamically adjust high-altitude fall prevention strategies. Edge computing devices enable large-scale deployment across buildings, preventing the danger of falling objects.

[0034] 2. AI-powered recognition methods that fuse multi-source data can detect objects falling from high-rise buildings. Based on the height and predicted trajectory of the falling object, the system proactively activates the anti-fall system to intercept it, preventing the impact of falling objects.

[0035] 3. By integrating multi-source data, the problem of high false alarm rate in existing technologies that rely solely on monocular camera vision is solved.

[0036] 4. Through the integration of multi-source data, the type and energy of falling objects from high altitude can be predicted, and the arresting force of the anti-fall system can be dynamically adjusted according to different falling situations.

[0037] 5. The falling object protection module features both soft and hard protective layers, effectively mitigating impact forces and intercepting falling objects. These layers are arranged alternately on each floor. The width of the protective layer increases as the floor descends, ensuring that falling objects are intercepted before they hit the ground.

[0049] The acquisition module monitors the high-altitude environment outside the building; the multi-source data collected in real time is transmitted to the high-altitude falling object detection and identification module, and the high-altitude falling object detection and identification module determines whether a high-altitude falling object has occurred based on the signals in the multi-source data; when it is confirmed to be a high-altitude falling object, an alarm is sent to the warning system in the falling area, and at the same time, the high-altitude falling object protection module is triggered to actively intercept the high-altitude falling object.

[0050] Specifically, the system consists of four parts: a data acquisition module, a high-altitude falling object detection and identification module, a high-altitude falling object protection module, and a warning system. The data acquisition module, which includes high-definition cameras, radars, and other data acquisition equipment, monitors the high-altitude environment outside the building.

[0052] This embodiment is a further optimization based on the embodiment 1, specifically:

[0053] The acquisition module is a multi-source data acquisition device, which includes a high-definition camera and a radar. The high-definition camera and the radar are installed on the building corresponding to the high-altitude falling object protection module and at the bottom of the building.

[0055] The falling object protection module includes multiple hard fall protection systems and multiple soft fall protection systems installed alternately from top to bottom on the building facade;

[0056] High-definition cameras and radars are connected to the input signals of edge computing devices;

[0057] The warning system, each hard fall prevention system, and each soft fall prevention system are all connected to the output signal of the edge computing device.

[0058] The widths of the hard fall protection system and the soft fall protection system in the deployed state increase sequentially from top to bottom.

[0059] The rigid fall prevention system includes a first vertical frame fixed to the facade of the building, a rigid protective layer hinged to the bottom edge of the first vertical frame, and multiple cables arranged at intervals on the edge of the rigid protective layer away from the hinged side. The other end of each cable is connected to the upper edge of the first vertical frame. The rigid protective layer is made of steel wire rope.

[0060] The soft fall prevention system includes a second vertical frame fixed on the facade of the building, a soft protective layer hinged to the bottom edge of the second vertical frame, and multiple second cables are arranged at intervals on the edge of the soft protective layer away from the hinged side. The other end of each second cable is connected to the upper edge of the second vertical frame.

[0061] The soft protective layer comprises a mounting frame hinged on the bottom of the second vertical frame. The mounting frame is provided with an outer layer safety airbag and an inner layer safety airbag sleeved on the inner side of the outer layer safety airbag.

[0062] Specifically, the falling object protection module features both soft and hard protective layers, effectively mitigating impact forces and intercepting falling objects. These layers are arranged alternately on each floor. The width of the protective layers increases as the floor descends, ensuring that falling objects are intercepted before they hit the ground.

[0063] The soft and hard protective layers share the same skeleton structure, differing primarily in the composition of the arresting layer.
