However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0042] At present, my country's construction has entered the stock era, and a large number of high-rise buildings are slowly becoming old buildings. As the buildings age, the probability of their exterior walls falling off gradually increases. Due to construction quality problems, the decorative layers of the exterior walls of many newly built high-rise buildings will fall off from time to time, posing a great safety hazard to people and objects under the buildings. In the existing technology, there is no effective early warning method for the falling of the exterior walls of buildings, so it is impossible to take preventive measures against the falling of the exterior walls of buildings in time. This application determines the stress change of the exterior wall of the building to be tested by detecting the resistance parameter change value of the stress sensing network, and further determines the position where the exterior wall of the building to be tested is about to fall off in combination with the preset alarm value, and realizes the quasi-falling position and sends a falling alarm in time.

[0043] The working principle of the stress sensing network is based on the strain principle. When an object undergoes stress changes and deformation due to external forces, the strain gauge is pasted on the stressed structure. When the structure is subjected to external forces, the strain gauge will deform accordingly. Due to the special properties of the internal material of the strain sensing network, the deformation will cause its resistance value to change, thereby sensing stress. This sensor usually includes elastomers, sensing components, measurement circuits and other parts, which can convert external stress into electrical signals for measurement. The entire system obtains the monitoring stress data of cracking, loosening and falling off of the surface layer of the building's exterior wall through each stress sensing network module, and decomposes and smoothes the real-time monitoring stress data according to the real-time monitoring stress data to obtain the real-time monitoring stress data. By identifying the change trend of the real-time monitoring stress data, whether there is a stress mutation point, if the tensile stress change at the mutation point is greater than the set alarm value, the information processing controller controls the display alarm device to alarm.

[0044] When the exterior wall of a building falls off, this is due to stress changes that cause the exterior wall to break or become damaged. The present application deploys a stress sensing net on the exterior wall of the building. When stress changes occur on the exterior wall of the building, the stress sensing net will be stretched and also produce stress changes. At this time, it is only necessary to calculate the stress changes of the stress sensing net and determine the stress mutation point to determine whether the exterior wall of the building will fall off, thereby issuing an alarm in a timely manner.

[0045] Figure 1 Schematic diagram of a real-time alarm method for building exterior wall shedding provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0046] S100, detecting the resistance parameter change value of the stress sensing network to determine the stress change of the exterior wall of the building to be tested.

[0047] A stress sensor is a sensor used to measure stress. Its working principle is based on measuring the deformation of an object after it is subjected to force, and the internal stress state of the object is inferred by measuring this deformation. Specifically, the stress sensor is attached to the structure under stress. When the building's exterior wall is subjected to external force, the strain sensor will deform accordingly. Due to the special properties of the material inside the stress sensor, the deformation will cause its resistance value to change, thereby sensing stress. This sensor usually includes an elastomer, a sensing component, a measurement circuit, etc., and can convert external stress into an electrical signal for measurement.

[0048] In the embodiment of the present application, the stress sensing network module is used as a stress sensor to determine the stress change of the exterior wall of the building to be tested. Figure 2 As shown, Figure 2 Schematic diagram of a stress sensing net module provided in an embodiment of the present application. The stress sensing net module includes a stress sensing net and a signal transmission line interface. A single stress sensing net module can be used as a stress sensor, or a stress sensing net module can be combined with an adjacent stress sensing net module to form an aggregated stress sensing net module as a stress sensor.

[0049] Specifically, the stress sensing net is a mesh structure of a preset size, and the mesh structure is a steel wire mesh wrapped with a conductive film.

[0050] In the embodiment of the present application, the stress sensing net is a mesh structure of preset size, and the size of the grid can be customized according to the detection accuracy, such as the grid size of 10cm×10cm, 5cm×5cm, etc., which is not specifically limited here, and the size of each module can also be customized according to needs, such as 1m×1m, 0.8m×0.8m, etc., which is not specifically limited here. In a possible implementation, each stress sensing net module will be coded and named according to the location of the wall on the floor, so as to facilitate accurate positioning when an alarm is triggered.

[0051] Since stress sensors usually include elastomers, sensing components, measurement circuits and other parts, in the embodiment of the present application, the mesh structure of the stress sensing net is a steel wire mesh wrapped with a conductive film. On the one hand, the steel wire mesh can be well stretched when stress changes occur. On the other hand, wrapping the conductive film can clearly detect the resistance parameter changes of the conductive film when the steel wire mesh is deformed, which is conducive to determining the stress change through the resistance parameter change.

[0052] Furthermore, the surface of the stress sensing net is in close contact with the surface layer of the exterior wall of the building to be tested, the stress sensing net is connected to a signal transmission line, the signal transmission line is connected to a signal processor, the resistance parameter change value of the stress sensing net is converted into a voltage signal, and the voltage signal is transmitted to the signal processor through the signal transmission line.

[0053] In an embodiment of the present application, a building exterior wall anti-falling alarm method is applied to a building exterior wall anti-falling alarm system, and the building exterior wall anti-falling alarm system includes a stress sensing network, a signal transmission line, a signal processor, a display and an alarm. Figure 3 Schematic diagram of the installation of a building exterior wall fall alarm system provided in an embodiment of the present application. Figure 3 As shown, the stress sensing net module is embedded under the exterior wall decoration layer or laid openly on the exterior wall surface. The outer surface of the stress sensing net module, i.e., the steel wire mesh wrapped with the conductive film, is embedded in the exterior wall finishing layer and is in close contact with the internal surface layer (such as a cement mortar bonding layer), or is laid openly on the surface of the exterior wall and is in close contact with the exterior wall surface. In this way, when the stress on the exterior wall surface changes, the stress sensing net can be quickly driven to deform. Therefore, the stress change of the stress sensing net can reflect the stress change of the exterior wall of the building. Each stress sensing module is connected in series through a signal transmission branch line, and each signal transmission branch line is connected to its corresponding signal processor. According to the strain principle, the resistance parameter change value of the stress sensing net is converted into a voltage signal, and the voltage signal is transmitted to the signal processor through the signal transmission branch line. Finally, multiple electrical signals processed by the signal processor are aggregated onto the signal transmission main line.

[0054] Furthermore, the stress sensing network and the signal transmission line are pre-buried inside the surface layer of the exterior wall of the building to be tested or fixed on the surface outside the surface layer of the exterior wall of the building to be tested.

[0055] In the embodiment of the present application, there are two deployment and installation methods for the stress sensing network. In one possible implementation method, for a newly built building, according to the importance of the building or the actual situation, the stress sensing network and the signal transmission line can be directly pre-buried under the exterior wall tiles, real stone paint, and paint layer finishing layer during the exterior wall decoration construction. Concealed installation means that the stress sensing network is pre-buried under the decorative layer of the exterior wall and cannot be directly observed. Figure 4 As shown, Figure 4 This is a schematic diagram of the concealed installation of the stress sensing net module on the building exterior wall provided in an embodiment of the present application. The surface layers in the schematic diagram are, from the outside to the inside, the exterior wall decoration surface, the stress sensing net pressed into the cement mortar bonding layer, the cement mortar bonding layer and the alkali-resistant fiber mesh cloth, the anti-cracking mortar, the thermal insulation layer and the interface bonding layer, and finally the exterior wall body, wherein the thermal insulation layer is determined by whether this structural layer exists according to the thermal insulation form, and the interface bonding layer is determined according to the form of the thermal insulation material.

[0056] In another possible implementation, for old buildings or key buildings that need to monitor the falling of the exterior walls, the stress sensing net and signal transmission line can be installed on the exterior walls that need to be monitored by nails, weather-resistant glue, etc. Since they are very fine wire mesh and wires, they are basically invisible from a distance and are in an invisible state, which does not affect the effect of the building's facade. Exposed installation means that the stress sensing net is deployed on the surface of the decorative layer of the exterior wall by pasting, etc. Although it can be directly observed, because the wire mesh and wires are very thin, transparent universal glue or other transparent pasting methods are used to make the stress sensing net in the exposed state also invisible, such as Figure 5 As shown, Figure 5 This is a schematic diagram of the exposed installation of the building exterior wall stress sensing net module provided in an embodiment, and the schematic diagram shows, from the outside to the inside, the stress sensing net, the exterior wall decorative surface, the cement mortar bonding layer, the alkali-resistant broken fiber mesh cloth, the anti-cracking mortar, the insulation layer and the interface bonding layer, and finally the exterior wall body, wherein the insulation layer is determined by whether this structural layer exists according to the insulation form, and the interface bonding layer is determined according to the insulation material form.

[0057] Step 100 of detecting the resistance parameter change value of the stress sensing network and determining the stress change of the exterior wall of the building to be tested specifically includes:

[0058] S101, detecting a resistance parameter change value of the stress sensing network to determine a stress mutation point of the exterior wall of the building to be tested;

[0059] S102, determining the stress change of the exterior wall of the building to be tested according to the stress change at the stress mutation point.

[0060] The dynamic strain field of the structure corresponds to the stress condition of each point. After fatigue, damage, or fracture of the structure, an abnormal strain field will be generated due to stress concentration. The strain force will suddenly change near the damage, and its degree will increase with the increase of the damage amount. In the embodiment of the present application, the stress mutation point of the exterior wall of the building to be tested is determined by detecting the change value of the resistance parameter of the stress sensing network, that is, the location where the exterior wall structure of the building to be tested is damaged. Because structural fatigue damage or fracture can easily cause the exterior wall of the building to fall off, after determining the stress mutation point, it is judged whether the exterior wall of the building to be tested will fall off according to the stress change of the spiritual force mutation point.

[0061] In a possible implementation, when multiple stress sensing networks are deployed simultaneously on the exterior wall of the building to be tested, the stress changes occurring at each stress mutation point are different, and it is necessary to analyze the shedding condition of the exterior wall structure of the building to be tested in combination with the mutation conditions of multiple stress mutation points.

[0062] S200, determining a quasi-falling-off position of the exterior wall of the building to be tested according to the resistance parameter change value and a preset alarm value, wherein the quasi-falling-off position is a position where the exterior wall of the building to be tested will fall off due to the stress change generated by the exterior wall of the building to be tested.

[0063] In the embodiment of the present application, the stress change of the exterior wall of the building to be tested obtained in S100 is used to determine whether the stress mutation point is damaged, that is, whether it is likely to fall off, according to the preset alarm value and the stress change. If the resistance parameter change value is greater than or equal to the preset alarm value, it means that there is a stress mutation point, and the location where the stress mutation occurs is the quasi-falling location. If the resistance parameter change value is less than the preset alarm value, it means that there is no stress mutation point, which may be other factors in the air that cannot be ignored, such as non-fracture or damage strain caused by temperature, and the exterior wall of the building will not fall off.

[0064] In the embodiment of the present application, due to objective conditions, it is necessary to eliminate interference strain when deploying the stress sensing network. Therefore, the method described in the present application also includes: before detecting the change value of the resistance parameter of the stress sensing network and determining the stress change of the exterior wall of the building to be measured, the method also includes: after deploying the stress sensing network, the initial stress of the exterior wall of the building to be measured is zeroed according to the temperature stress.

[0065] In the embodiment of the present application, after the stress sensing network is deployed, the resistance of the stress sensing network is tested first and converted into stress to eliminate the influence of temperature stress. The current stress is reset to zero in the system to put the entire system in an initial zero state. After eliminating the influence of initial temperature stress, a suitable stress alarm value is set.

[0066] S300, displaying the quasi-fall-off position and providing an alarm feedback.

[0067] In the embodiment of the present application, the quasi-fall-off position determined in S200 is displayed on a display, and an alarm is fed back to the operator through the alarm module. The information processing controller controls the display alarm device to sound an alarm. The display device will display the specific position of the outer wall of the floor where the module is located in real time according to the alarm of the specific module. At the same time, the property management and other personnel APP will also synchronously display the specific position and sound an alarm, so that the outer wall can be inspected in time and the hidden danger of outer wall falling can be eliminated in time.

[0068] Specifically, the method further includes:

[0069] According to the inspection of the quasi-falling-off position by the drone, it is determined whether there is a false alarm at the quasi-falling-off position;

[0070] If there is, a false alarm feedback is sent and the alarm of the quasi-fall-off position is released.

[0071] In the embodiment of the present application, the exterior wall fall prevention management personnel or property management personnel use drones to patrol according to the specific location of the alarm to determine whether there is a false alarm at the quasi-falling position. If there is a false alarm, false alarm feedback is sent and the alarm at the quasi-falling position is canceled, and silencing and resetting are performed on the system. When inspection shows that there are indeed cracks and looseness, repair treatment is required to eliminate the safety hazards of exterior wall falling in time to ensure the safety of people's lives and property.

[0072] Figure 6 Schematic diagram of the working principle of a building exterior wall fall alarm system provided in an embodiment of the present application. Figure 6 As shown, the information processing controller is connected with the stress sensing network, the position alarm display, the sound and light alarm and the APP alarm. The information processing controller receives the electrical signal generated by the deformation of the stress sensing network due to the shedding of the exterior wall through the signal transmission line. If the resistance parameter change value is greater than or equal to the preset alarm value, the alarm module sends an alarm signal at this time, and the information processing controller controls the camera to perform an impact inspection and comparison on the alarm part to determine whether the exterior wall is in a normal state. If the exterior wall is in a normal state, it is determined to be a false alarm, the alarm is silenced and the signal is reset. If the exterior wall is in a quasi-shedding state, the personnel under the exterior wall of the building are notified to evacuate, and the shedding position of the exterior wall of the building is given a real-time alarm, which is beneficial to improve the guarantee of preventing the shedding of the exterior wall of the building from causing loss of personnel and property.

[0073] Figure 7 : is a schematic diagram of the logic flow of the building exterior wall anti-falling alarm provided by the embodiment of the present application, such as Figure 7 As shown, the anti-falling alarm method for building exterior walls provided by the present application first installs a stress sensing net module on the exterior wall of the building, and then performs address coding on each installed stress sensing net module, which is convenient for accurate positioning when the alarm occurs. Then, the resistance parameter change value on the stress sensing net module is converted into an electrical signal and connected to the information processor by a signal transmission line. The stress alarm value is set by the information processor. When the exterior wall cracks, loosens, leaks, and is pulled, the stress sensing net will also be stretched. If the resistance value change value exceeds the preset alarm value, the fall-off position is displayed through the alarm device and an APP alarm is issued. At the same time, the fall-off of the exterior wall is detected by drone photography to determine whether there is a false alarm. If it is a false alarm, an alarm is triggered to eliminate the risk of exterior wall fall-off.
