Description

The present invention relates to a monitoring and feedback system and an operating method thereof, and in particular to a monitoring and feedback system for building structures and an operating method thereof.

The current earthquake control plan for buildings only targets strengthening the strength of steel beams and adding dampers to the structure. However, the vibration mode of the building structure and the information on the weak side structure cannot be obtained, so the installed dampers or diagonal braces must be calculated by structural technicians, and the dampers cannot be installed in effective positions. In other words, there is still a blind spot in the correction of the structural strength of specific locations in the building.

In addition, when an earthquake or strong wind occurs, the high-rise structures of buildings are easily affected and displaced, making the higher the floors, the easier it is to shake. Furthermore, old houses or buildings may be damaged by ground subsidence and strong earthquakes, and weak structural areas or unsupported soft feet may occur in fixed structural locations. At this stage, it is still impossible to effectively monitor.

Therefore, the directional terms used are used to explain and understand the present invention, not to limit the present invention.

Please refer to FIG. 1, which is an embodiment of the monitoring and feedback system of the present invention for building structures. The monitoring and feedback system includes multiple sensing modules 2, a computing module 3, and a processing module 4. The present invention will describe in detail the detailed structure, assembly relationship and operating principle of each component below.

Continuing with reference to FIG. 1 , the sensing modules 2 are disposed in at least one building structure (not shown), and each sensing module 2 is configured to sense the building structure and generate a sensing value corresponding to the building structure, such as stress value, strain value, vibration value, displacement value, acceleration value, and level measurement value. In this embodiment, the sensing modules 2 are respectively located in multiple floors of the building structure, and the sensing modules 2 are one or more of a stress sensor, a strain sensor, a vibration sensor, a displacement sensor, an acceleration sensor, and a level.

Continuing to refer to FIG. 1 , the computing module 3 is electrically connected to the sensing modules 2, and the computing module 3 is configured to receive the sensing values sent from the sensing modules 2 to establish a structural mode of the building structure, wherein the computing module 3 periodically receives the sensing values to obtain multiple vibration modes of the building structure in different periods.

Continuing to refer to FIG. 1 , the processing module 4 is electrically connected to the operation module 3 , and the processing module 4 is configured to compare the sensing values of different cycles and the vibration modes of different cycles, thereby generating a first feedback signal.

According to the above structure, the monitoring and feedback system for building structures of the present invention is in a passive state, and the passive state is used to obtain the structural mode of the building structure, wherein the building structure, such as a building, is installed with the sensing modules 2, such as stress or strain sensors, accelerometers, spirit levels, etc., in multiple floors, and the computing module 3 and the processing module 4 (i.e., the central processing unit) are set in the building, wherein the above sensing values can be transmitted by wired and wireless methods, and the vibration mode (vibration mode) of the building and the structural modeling of the building are obtained through the computing module 3, and the vibration modes of different periods are compared. In this embodiment, the sensing modules 2 are installed in the building structure, so as to capture sensing values at different floors. The sensing modules 2 can sense stress, strain, acceleration, and floor level. Small earthquakes can obtain stress at each location through the strain gauges of the sensing modules 2 to infer the strain of each floor of the building.

As described above, by periodically receiving the sensing values through the computing module 3, the vibration mode of the building structure can be evaluated and established, and then dampers or shear plates can be added to the large displacement of the building structure. In addition, the sensing values can also evaluate whether there is a pull-out force that separates the steel bars from the cement. In other words, the sensing modules 2 are used to sense short-term changes. If there is an abnormal frequency of vibration, it can be determined by the sensing values whether it is a structural problem. If multiple building structures are equipped with the sensing modules 2, the building structures are connected through the sensing modules 2, and satellite positioning (such as GPS) or the device itself can be used for positioning to define the distance between the building structures. Furthermore, when the sensing modules 2 are installed in multiple building structures, when an earthquake occurs, the sensing modules 2 in the building structures closer to the earthquake source sense the earthquake magnitude and earthquake source direction, and then send the earthquake information corresponding to the earthquake source direction to the building structures farther from the earthquake source to estimate the magnitude response, thereby shortening the response time to the earthquake disaster.

Please refer to Figures 2 and 3, which are another embodiment of the monitoring and feedback system for building structures of the present invention, which is similar to the above embodiment and generally uses the same component names and figure numbers, wherein the monitoring and feedback system includes multiple sensing modules 2, a computing module 3, and a processing module 4, the difference is that: the monitoring and feedback system also includes multiple dampers 5 and one or more damping controllers 6, the present invention will be described in detail below the detailed structure, assembly relationship and operation principle of each component.

In this embodiment, the dampers 5 are respectively located in multiple floors of the building structure, and each damping controller 6 is configured to adjust the damping value of the dampers 5 and the phase difference in the time period according to the first feedback signal, and the dampers are one or more of liquid velocity-dependent dampers, buckling beam diagonal dampers, tempered dampers, metal dampers, friction dampers, damping walls, viscoelastic damping walls, and seismic isolation pads.

According to the above structure, the monitoring and feedback system for building structures of the present invention is in an active state, and the active state is used to actively suppress the shaking of the building structure, wherein the building structure, such as a building, is installed with the sensing modules 2, such as stress or strain sensors, accelerometers, and level meters, etc., in multiple floors, and the computing module 3 and the processing module 4 (i.e., the central processing unit) are set in the building. , wherein the above-mentioned sensing values can be transmitted by wired and wireless means, the vibration mode of the building is obtained through the calculation module 3, and then the vibration modes of different periods are compared, and the damping value of the dampers 5 is adjusted by the damping controller 6 (adjusting the phase over time), and finally the sensing values obtained by the sensing modules 2 located on each floor of the building are compared and the damping value is corrected, thereby suppressing the shaking of the building structure.

Furthermore, the aspect ratio, directionality, force direction of the structure and foundation stability of the building will affect its amplitude and the weaker area of the structure, so the dampers 5 can adjust the corresponding damping value according to the earthquake direction. In addition, the dampers 5 can also reduce the shaking of the building structure and absorb shock when a small earthquake or strong wind occurs. If a large earthquake occurs, adjusting the damping value of the dampers 5 can reduce the stress of the structure from exceeding the critical value. The monitoring and feedback system of the present invention for building structures can use the sensing modules 2 located on different floors for sensing. At the location where the deformation of the building structure is large, the dampers 5 are used to adjust the phase difference, which can absorb more displacement energy to reduce the damage to the building structure.

When the sensing values of the sensing modules 2 are abnormal (structural weakening), a second warning message is issued through the warning unit 7, for example, a warning is issued to the building structure of a specific building.

Furthermore, the evaluation data is used to determine the structural weakening degree of the building structure. For example, when a strong earthquake event or a transient signal event (such as a weak earthquake or a strong wind) occurs, after the sensing values of the sensing modules 2 are transmitted to the cloud computing comparison unit 8 via the computing module 3, the cloud computing comparison unit 8 stores the sensing values of the building structure and the sensing modules 2, such as weak earthquakes, strong winds, strong earthquakes, earthquake source directions, etc., to form a sensing value database, and then compares the original structural characteristics of the building structure (such as vibration type or mode comparison) to determine whether the building structure has a structural weakening degree after a strong earthquake event or a transient signal event occurs.
