[0001] The present invention relates to the technical field of real-time monitoring, and particularly to a real-time monitoring device for wind-induced vibration of high-rise buildings based on machine vision. Background Technique
[0002] The real-time monitoring device for wind-induced vibration of high-rise buildings usually consists of sensors, a data acquisition system, a data processing and analysis system, and an alarm and early warning system. These devices can capture the vibration response of high-rise buildings under wind loads in real time and through data analysis and processing techniques.
[0003] However, since the sensor is easily affected by high temperature during recording, when the temperature around the detector changes, the resistance, capacitance and other characteristics of the transmission line will change, resulting in unstable signal strength received at the receiving end and even signal distortion. Moreover, since the detector is set at a high-rise building, it is easy to cause direct sunlight, making the device temperature too high. The high-temperature environment may make the electromagnetic environment around the controller complex, generating more electromagnetic interference signals and reducing the working efficiency.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. For the real-time monitoring device of wind-induced vibration of high-rise buildings based on machine vision, the compressed gas generated by the movement inside the air valve is transmitted through the connecting pipe to the vortex tube. The gas inside the vortex tube is divided into hot air and cold air and transported to both ends. When the temperature inside the detector housing is too high, the setting of the temperature controller effectively avoids inaccurate detection results caused by too high or too low temperature. Moreover, the change in temperature will cause changes in the resistance, capacitance, etc. of the transmission line, resulting in an increase or decrease in the loss during signal transmission, making the signal intensity received by the receiving end unstable and even signal distortion. Since the detector is set at a high-rise building, it is prone to direct sunlight, and the high-temperature environment may make the electromagnetic environment around the detection device complex, generating more electromagnetic interference signals, interfering with the transmission and processing of vibration monitoring signals, and causing noise in the signals, etc.
[0013] 2. For the real-time monitoring device of wind-induced vibration of high-rise buildings based on machine vision, when reset is required after detection, the controller opens the door panel set on the inner wall of the observation chamber near the connecting pipe, so that the hot air passing through the heating component blows towards the L-shaped detection rod through the connecting pipe. A part of the hot air separated from the heating component blows towards the L-shaped detection rod through the connecting pipe to restore the L-shaped detection rod. The shape memory alloy can withstand multiple cycles of shape change without significantly reducing its shape memory performance. The shape memory alloy can stably perform shape restoration during long-term use, ensuring the reliability and stability of the system and maintaining a high shape recovery rate, avoiding the need for timely disassembly and replacement after detection for a period of time, reducing a series of problems caused by manual replacement. Moreover, while having the shape memory effect, the shape memory alloy also has good mechanical properties, such as high strength, toughness, and fatigue resistance, etc. This enables it to withstand certain external forces and loads during the process of shape restoration and will not easily break or be damaged due to frequent deformation and restoration.
[0014] 3. For the real-time monitoring device of wind-induced vibration of high-rise buildings based on machine vision, after the cylinder impacts the push plate, the impact frequency of the cylinder can be reflected in the rotation speed of the fan. When the fan rotates, the observer can obtain accurate numbers from the display screen for convenient recording. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer toFigure 1-14 , a real-time monitoring device for wind-induced vibration of high-rise buildings based on machine vision, comprising a detector housing 1. A lifting plate 2 is provided on the outer wall of the detector housing 1. A rotating blade 5 is provided at the top of the detector housing 1. A fixed seat 9 is fixedly connected to the bottom of the rotating blade 5. A connecting column 10 is provided at the bottom of the fixed seat 9. A transmission assembly 11 is provided at the bottom of the connecting column 10. A communicating pipe 12 is provided on the outer wall of the transmission assembly 11. An eddy current tube 13 is provided on the outer wall of the communicating pipe 12. One end of the eddy current tube 13 is fixedly connected to a heating assembly 14. The other end of the eddy current tube 13 is fixedly connected to a cooling assembly 15. A connecting pipe 16 is fixedly connected to the outer wall of the heating assembly 14. A controller 19 is provided on the outer wall of an observation chamber 17. A detection assembly 18 is provided on the inner wall of the observation chamber 17; The detection assembly 18 includes a cylinder 181 located on the inner wall of the observation chamber 17. A spherical joint 183 is rotatably connected to the inner wall of the cylinder 181. An L-shaped detection rod 182 is fixedly connected to the top of the cylinder 181. A plurality of dust-proof housings 185 are fixedly connected to the top of the observation chamber 17. The plurality of dust-proof housings 185 are symmetrically distributed on the outer wall of the cylinder 181. A gear set 188 is provided on the inner wall of the dust-proof housing 185. A push plate 184 is fixedly connected to the bottom of the gear set 188. A spring 189 is provided on the outer wall of the push plate 184. A fixing rod 187 is provided on the outer wall of the push plate 184 on the side away from the spring 189. A fan 186 is fixedly connected to the outer wall of the dust-proof housing 185.
[0019] It should be noted that after the top rotating blade 5 is affected by the wind and starts to rotate, it is convenient for the monitoring personnel to observe the real-time situation. When the temperature around the detector housing 1 changes, the resistance, capacitance and other characteristics of the transmission line will change, resulting in unstable signal strength received by the receiving end and even signal distortion. Moreover, since the detector housing 1 is installed at a high-rise building, it is easy to cause direct sunlight, making the temperature inside the detector housing 1 too high. The high-temperature environment may make the electromagnetic environment around the controller complex and generate more electromagnetic interference signals; The observation chamber 17 is made of a visible material, which is convenient for better observing the real-time situation during monitoring. Since the cylinder 181 is made of metal, a counterweight is provided at the bottom of the cylinder 181. When the cylinder 181 shakes, the thrust causes the L-shaped detection rod 182 to bend. The L-shaped detection rod 182 is made of shape memory metal. When the cylinder 181 sways, since one end of the L-shaped detection rod 182 is fixed on the observation chamber 17 and the other end abuts against the outer wall of the cylinder 181, a scale bar is provided on the L-shaped detection rod 182, and the amplitude of the high-rise building's sway can be judged according to the scale corresponding to the bending of the L-shaped detection rod 182. The swing of the cylinder 181 will push the bottom push plate 184. The outer wall of the bottom push plate 184 is fixed on the dust-proof housing 185 through the fixing rod 187. The top of the dust-proof housing 185 is fixedly connected to the inner wall of the observation chamber 17. Since a gear set 188 is provided on the outer wall of the push plate 184, when the cylinder 181 impacts the push plate 184, the impact frequency of the cylinder 181 can be observed by the speed of the fan 186 rotating. After the impact force of the cylinder 181 disappears on the push plate 184, since a spring 189 is connected to the outer wall of the push plate 184, the spring 189 can drive the push plate 184 to return to the initial position. When the fan 186 rotates, it is beneficial to accelerate the rapid flow of the cold air or hot air blown into the observation chamber 17, so that the inside of the detector housing 1 can be adjusted to a suitable temperature faster, effectively promoting the internal circulation in the detector housing 1 and effectively ensuring that the inside of the observation chamber 17 is in a constant temperature state; When resetting is required after the detection is completed, the controller 19 opens the door panel provided on the inner wall of the observation chamber 17 near the connecting pipe 16, so that the hot air passing through the heating component 14 blows towards the L-shaped detection rod 182 through the connecting pipe 16. Since the L-shaped detection rod 182 is a shape memory alloy, the increase in temperature will cause the L-shaped detection rod 182 to recover. The shape memory alloy can withstand multiple cycles of shape changes without significantly reducing its shape memory performance. The shape memory alloy can stably perform shape recovery during long-term use, ensuring the reliability and stability of the system and maintaining a high shape recovery rate, avoiding the need for timely disassembly and replacement after a period of detection, reducing a series of problems caused by manual replacement, and the shape memory alloy also has good mechanical properties while having the shape memory effect, such as high strength, toughness, and fatigue resistance. This enables it to withstand a certain amount of external force and load during the process of shape recovery and will not easily break or be damaged due to frequent deformation and recovery.
[0020] In an alternative embodiment: The detection assembly 18 further includes a display screen 1810 located on the inner wall of the observation chamber 17.
[0021] It should be noted that after the fan 186 rotates, the observer can obtain the rotation speed of the fan 186 from the display screen 1810, which is convenient for recording accurate data.
[0022] In an alternative embodiment: The cylinder 181 is made of iron, and the L-shaped detection rod 182 is made of shape memory alloy.
[0023] It should be noted that the cylinder 181 is made of iron and is provided with a counterweight at the bottom. When hot and cold air is blown into the detector housing 1 through the first air outlet 154 and the second air outlet 142 to adjust the temperature, it avoids the situation of random deviation after being blown due to the lack of a counterweight, reducing the detection accuracy.
[0024] In an alternative embodiment: The transmission assembly 11 includes a third driving motor 111 located on the inner wall of the detector housing 1. The outer wall of the third driving motor 111 is rotatably connected to a rotating block 112. The outer wall of the rotating block 112 is fixedly connected to a first sliding block 113. The outer wall of the first sliding block 113 is slidably connected to a connecting rod 114. The bottom of the connecting rod 114 is fixedly connected to a limiting block 115. The outer wall of the limiting block 115 is fixedly connected to a moving long rod 116. The top of the moving long rod 116 is fixedly connected to a connecting plate 6. The outer wall of the moving long rod 116 is fixedly connected to a piston 118. Both ends of the outer wall of the moving long rod 116 are sleeved with air valves 117.
[0025] It should be noted that when the third driving motor 111 is started, it drives the rotating block 112 to rotate. After the rotating block 112 rotates, it drives the first sliding block 113 to slide. The inner wall of the connecting rod 114 is provided with a limiting groove adapted thereto. The limiting groove effectively limits the first sliding block 113 and one end of the connecting rod 114 is fixed to the detector housing 1. When the first sliding block 113 slides, it drives the connecting rod 114 to move left and right reciprocally. The moving long rod 116 is slidably connected to the detector housing 1 through the connecting plate 6 fixedly connected to the top. When the moving long rod 116 moves reciprocally, the gas in the top air valve 117 is transmitted into the vortex tube 13, providing compressed gas for the vortex tube 13, making the interior of the detector housing 1 at a suitable temperature and improving the detection accuracy of the detection assembly 18.
[0026] In an alternative embodiment: The cooling assembly 15 includes a cold air outlet pipe 151 located on the outer wall of the vortex tube 13. The outer wall of the cold air outlet pipe 151 is fixedly connected to a first air outlet 154. The outer wall of the first air outlet 154 is provided with a first connecting plate 153. The outer wall of the first connecting plate 153 is fixedly connected to a first placement box 152. The outer wall of the first placement box 152 is fixedly connected to a second sliding block 155 on the side away from the first connecting plate 153. The bottom of the second sliding block 155 is provided with a second connecting plate 156.
[0027] It should be noted that since the vortex tube 13 will deliver a part of the cold air to the cold air outlet duct 151 and then blow it out of the device through the cold air outlet 8, and since the first connecting plate 153 blocks the first air outlet 154, the cold air cannot be blown into the device through the first air outlet 154. When the temperature rises and cold air needs to be transmitted to the interior, due to the temperature affecting the flexible first placement box 152, after an appropriate amount of carbon dioxide expands in volume, it pushes the second sliding block 155 on the outer wall of the first placement box 152 and the first connecting plate 153 at the bottom to move backward simultaneously. Since the size of the second connecting plate 156 is adapted to the cold air outlet duct 151, the moved second connecting plate 156 blocks the cold air outlet duct 151, and the first connecting plate 153 that blocks the first air outlet 154 is removed, enabling the cold air to be blown into the interior of the detection device through the first air outlet 154 for effective cooling.
[0028] In an alternative embodiment: The size of the first connecting plate 153 is adapted to the first air outlet 154, and the size of the second connecting plate 156 is adapted to the size of the cold air outlet duct 151.
[0029] It should be noted that since the size of the first connecting plate 153 is adapted to the first air outlet 154, when internal cooling is not required, the first connecting plate 153 effectively blocks it, reducing the discharge of cold air and increasing the accuracy of the device.
[0030] In an alternative embodiment: The heating component 14 includes a hot air outlet duct 141 located on the outer wall of the vortex tube 13. A second air outlet 142 is fixedly connected to the outer wall of the hot air outlet duct 141. A moving plate 144 is provided on the inner wall of the second air outlet 142, and a second placement box 143 is provided on the top of the moving plate 144.
[0031] It should be noted that when the temperature is too low, the carbon dioxide stored in the second placement box 143 begins to contract, and the moving plate 144 that originally blocked the second air outlet 142 begins to move upward, sending hot air to the second air outlet 142 to raise the internal temperature.
[0032] In an alternative embodiment: A fixing plate 4 is fixedly connected to the outer wall of the detector housing 1. A driving motor 3 is provided on the outer wall of the detector housing 1 on the side close to the lifting plate 2. A hot air outlet 7 is provided on the outer wall of the detector housing 1, and the position of the hot air outlet 7 corresponds to the position of the heating component 14. A cold air outlet 8 is provided on the outer wall of the detector housing 1, and the position of the cold air outlet 8 corresponds to the position of the cooling component 15.
[0033] It should be noted that when the driving motor 3 is turned on, the driving motor 3 drives the lifting plate 2 to move upward, which is convenient for the device to observe the swaying of high-rise buildings in windy conditions. When detection is not required, it can be manually turned off, effectively preventing the temperature of the device from rising due to direct sunlight when monitoring is not needed, and reducing the error caused by temperature. When the gas enters the vortex tube 13, it forms a high-speed rotating air flow. The air flow near the center of the pipe has a high rotational angular velocity, and the air flow near the pipe wall has a low rotational angular velocity. There is viscous friction between the air flow layers. When the gas forms a vortex in the vortex tube, there is a pressure difference inside the pipe. The outer ring gas is at high pressure, and the hot air will flow outward and be diverted to one side, while the cold air flows in the inner ring and is diverted to the other side. The hot air in the hot air outlet pipe 141 blows out of the device from the hot air outlet 7, and the cold air at the cold air outlet pipe 151 blows out of the device from the cold air outlet 8, effectively ensuring that the internal temperature always remains at a constant temperature.
[0034] Working principle: When the top rotating blade 5 is affected by the wind force, it starts to rotate, and the driving motor 3 drives the lifting plate 2 to move upward, which is convenient for the device to observe the swaying of high-rise buildings in windy conditions. After the rotating block 112 rotates, it drives the first sliding block 113 to slide. The inner wall of the connecting rod 114 is provided with a limiting groove adapted to the first sliding block 113, and effectively limits the first sliding block 113. When the first sliding block 113 slides, it drives the connecting rod 114 to move. One end of the connecting rod 114 is fixed with a limiting block 115, and the limiting block 115 drives the connected moving long rod 116 to reciprocate. The moving long rod 116 is slidably connected to the detector housing 1 through the connecting plate 6 fixedly connected to the top. When the moving long rod 116 reciprocates, it drives the piston 118 to move, so that the compressed gas is transmitted into the vortex tube 13 through the connecting pipe 12, providing compressed gas for the vortex tube 13. When the gas enters the vortex tube, a high-speed rotating air flow is formed. The air flow near the center of the pipe has a high angular velocity of rotation, and the air flow near the pipe wall has a low angular velocity of rotation. There is viscous friction between the air flow layers. When the gas forms a vortex in the vortex tube, there is a pressure difference inside the pipe. The outer ring gas is at high pressure, and the hot air will flow outward and be diverted to one side, while the cold air flows in the inner ring and is diverted to the other side. The vortex tube 13 will transport a part of the cold air to the cold air outlet pipe 151 and then blow it out of the equipment through the cold air outlet 8. Since the first connecting plate 153 blocks the first air outlet 154, the cold air cannot be blown into the equipment through the first air outlet 154. When the temperature rises and cold air needs to be transmitted to the inside, due to the temperature affecting the flexible first placement box 152, the volume of an appropriate amount of carbon dioxide begins to expand and then pushes the second sliding block 155 on the outer wall of the first placement box 152 and the first connecting plate 153 at the bottom to move backward at the same time. Since the size of the second connecting plate 156 is adapted to the cold air outlet pipe 151, the moved second connecting plate 156 blocks the cold air outlet pipe 151, and the first connecting plate 153 that originally blocked the outer wall of the first air outlet 154 is removed, so that the cold air is blown into the detection equipment through the first air outlet 154 for effective cooling; When the temperature is too low, the carbon dioxide stored in the second placement box 143 begins to contract. Since the second air outlet 142 is blocked by the moving plate 144, the gas cannot be blown into the equipment. After the temperature changes and the volume of the second placement box 143 begins to shrink, the moving plate 144 moves upward, and the hot air can pass through the second air outlet 142 and be blown into the equipment to increase the temperature inside the equipment; Since the observation chamber 17 is made of a visible material to better observe the actual situation, when the high-rise building is affected by wind and vibrates, since the cylinder 181 is made of metal and a counterweight is provided at the bottom of the cylinder 181, when the cylinder 181 shakes, the L-shaped detection rod 182 bends after being subjected to a thrust force. Since the material of the L-shaped detection rod 182 is a memory metal, when the cylinder 181 sways, the angle of the high-rise building's sway can be judged according to the scale corresponding to the bending of the L-shaped detection rod 182. When the frequency of the cylinder 181 is too fast or too slow, it will push the bottom push plate 184. Since a gear set 188 is provided on the outer wall of the push plate 184, when the cylinder 181 impacts the push plate 184, the impact frequency of the cylinder 181 can be observed by the speed of rotation of the fan 186. And when the impact force of the cylinder 181 disappears on the push plate 184, since a spring 189 is connected to the outer wall of the push plate 184, the spring 189 can drive the push plate 184 to return to its initial position. The rotation of the fan 186 helps to accelerate the rapid flow of the cold or hot air blown into the observation chamber 17, enabling the inside of the detector housing 1 to be adjusted to a suitable temperature more quickly, effectively promoting the internal circulation inside the detector housing 1. When it is necessary to reset the L-shaped detection rod 182 after the detection is completed, the controller 19 is activated. The controller 19 opens the door panel provided on the inner wall of the observation chamber 17 near the connecting pipe 16. A part of the hot air branched from the heating component 14 blows towards the L-shaped detection rod 182 through the connecting pipe 16 to restore the L-shaped detection rod 182 to its original state.
[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
