The surfaces of the extension plate 401 and the arc blade 303 are both embedded with a three-dimensional mesh structure made of Ni-Ti alloy wire (phase change temperature 40°C). The three-dimensional mesh structure can increase the contact area between the material and the surface of the extension plate 401 and the arc blade 303, thereby distributing the shrinkage force more evenly and improving the compression effect of the connection interface.

[0020] The embodiment of the present invention is also implemented through the following technical solutions.

[0021] In the embodiment of the present invention, the ends of the hydraulic cylinder 201 and the telescopic rod 202 are fixed with connecting heads 203, the hydraulic cylinder 201 is screwed to the outer frame 101 through the connecting head 203, the hydraulic cylinder 201 is installed on the outer frame 101 through the connecting head 203, a connecting plate 204 is arranged between the connecting head 203 on the telescopic rod 202 and the cover plate 102, the connecting plate 204 is rotatably connected to the connecting head 203, the connecting plate 204 is screwed to the cover plate 102, the telescopic rod 202 is installed on the cover plate 102 through the connecting plate 204, and the angle of the connecting plate 204 at the connecting head 203 is adjustable, according to the force point of the cover plate 102 and the rationality of the internal structure of the outer frame 101, the hydraulic cylinder 201 can be tilted, and the angle of the connecting plate 204 can be adjusted for adaptive installation.

[0022] Specifically, the telescopic rod 202 is driven to rise and fall by the hydraulic cylinder 201 using the connecting head 203 and the connecting plate 204, the outer frame 101 is connected to the cover plate 102, and the cover plate 102 is supported by hydraulic pressure, so that the cover plate 102 can be stably maintained in the desired position after being raised, and the cover plate 102 will not fall off easily. The cooperation principle of the hydraulic cylinder 201 and the telescopic rod 202 is: the hydraulic cylinder 201 is integrated with the motor, pump and other components to reduce the overall volume and form a compact module. The hydraulic cylinder 201 is a cylindrical sleeve, and a piston is arranged inside the cylinder body, which fits tightly with the inner wall of the cylinder body, and the hydraulic oil leakage is prevented by the seal. The piston is under the pressure of the hydraulic oil. The telescopic rod 202 is connected to one end of the piston and is usually made of high-strength alloy steel. The telescopic rod 202 extends out of the cylinder body through a sealing device at the front end of the cylinder body. The sealing device includes seals at both ends of the cylinder body and seals on the piston, which are used to prevent hydraulic oil leakage and external impurities from entering the cylinder body. When the hydraulic oil is pumped into the cylinder body, the piston is acted upon by the oil pressure, pushing the piston to move along the axis of the cylinder body. The movement of the piston drives the telescopic rod 202 to extend or retract into the cylinder body. The telescopic movement of the telescopic rod 202 is transmitted to the cover plate 102, controlling the lifting and lowering of the cover plate 102, so that the cover plate 102 will not be easily opened, and the cover plate 102 can be supported.

[0023] Considering the volume of the support member 200, existing micro hydraulic equipment, such as the HSG series micro hydraulic cylinder 201, the MG series compact hydraulic cylinder 201, the TUFF-TORQ series small hydraulic cylinder 201, etc., can be directly selected.

[0024] In the embodiment of the present invention, the output end of the motor 302 is connected to the rotating column 301 in a transmission manner. At least two arc-shaped blades 303 are fixed on the outer side of the rotating column 301. The rotating column 301 serves as a transmission component of the output end of the motor 302 to transmit the rotational motion of the motor 302 to the arc-shaped blades 303. The clamping hole 402 is designed as a through hole. The arc-shaped blades 303 pass through the extension plate 401 through the clamping hole 402 and are movably connected to the extension plate 401. The size and shape of the clamping hole 402 match the cross-section of the arc-shaped blades 303 to ensure that the blades can pass through smoothly and remain stable. The arc-shaped blades 303 and the extension plate 401 are connected by the clamping hole 402. 1, the clamping hole 402 and the connecting hole 403 are staggered, the extension plate 401 is provided with the clamping hole 402 and the connecting hole 403 through the surface, which are used to cooperate with the arc blade 303 and the connecting column 304, the connecting hole 403 is a blind hole, the depth of the connecting hole 403 is 5cm±0.01cm, the stress release micro-pits at the bottom of the connecting hole 403, the micro-pits are hemispherical pits with a diameter of 0.1cm, when the temperature changes ΔT=50℃, the micro-pits compensate for the thermal deformation of 0.005mm, and the hole stalks located in the connecting hole 403 are used to compensate for the thermal deformation. When the temperature changes, the micro-pits can absorb or release the thermal expansion or contraction of the material.

[0025] Specifically, the motor 302 provides rotational power, which is transmitted to the outer arc-shaped blade 303 through the rotating column 301. The rotational movement of the arc-shaped blade 303 is transmitted to the extension plate 401 through the connecting column 304, thereby realizing the transmission and conversion of power. The micro-pits are designed to absorb the thermal expansion or contraction of the material caused by temperature changes, thereby maintaining the stability and precision of the connecting part 300.

[0026] In the embodiment of the present invention, the clamping hole 402 and the connecting hole 403 are both processed by electrolytic polishing. The electrolytic polishing process improves the surface quality and reduces friction. The connecting column 304 is arranged near the midpoint of the arc-shaped blade 303. The front end of the connecting column 304 is provided with a protruding block 305. The interior of the connecting hole 403 is provided with a clamping plate 404 adapted to the protruding block 305. The clamping plate 404 is arranged inside the connecting hole 403 for fixing the connecting column 304. The rear end of the protruding block 305 is provided with a spring 306. The two ends of the spring 306 are respectively fixedly connected to the arc-shaped blade 303 and the protruding block 305. The spring 306 provides elasticity and buffering, allowing a certain amount of expansion and contraction and deformation. The use of the spring 306 and the rubber material provides elastic buffering, reduces impact and vibration, and protects the connecting piece 300 and the steel column 400. When the connecting piece 300 is subjected to external force, the spring 306 will deform. It absorbs part of the impact force, thereby reducing the direct impact on the connecting piece 300. The deformation of the spring 306 also provides a certain expansion and contraction space, allowing the connecting piece 300 to expand and contract within a certain range to adapt to temperature changes or other external factors. When the external force is released, the spring 306 will return to its original state, and push the connecting column 304 back to its initial position through its restoring force to achieve elastic buffering. The use of the spring 306 improves the stability and reliability of the connecting piece 300, so that it can maintain a stable connection when it is impacted or vibrated. Two clamping plates 404 are arranged in the connecting hole 403, and a rotating end 405 is arranged at the end of the clamping plate 404. A threaded rod is arranged between the rotating end 405 and the inner wall of the connecting hole 403. The threaded rod passes through the rotating end 405 and is threadedly matched with the rotating end 405. The threaded rod provides additional fixation and stability. The connecting column 304 and the protruding block 305 are both rubber designed.

[0027] Specifically, the motor 302 is embedded in the inner bottom surface of the outer frame 101 to ensure that the motor 302 is firmly fixed, the rotating column 301 is fixed to the output end of the motor 302 to ensure the transmission connection between the rotating column 301 and the motor 302, and the connecting column 304 is set on the inner side of the arc-shaped blade 303, close to the midpoint of the arc-shaped blade 303, and two clamping plates 404 are set in the connecting hole 403. When the steel column 400 is connected to the connecting block 100, the motor 302 is started, and the rotating column 301 drives the arc-shaped blade 303 to rotate. The arc-shaped blade 303 rotates to the extension plate 401 and passes through the clamping hole 402. When the protruding block 305 of the connecting column 304 is inserted into the connecting hole 403, the clamping plate 404 will be stretched open by the protruding block 305, and the clamping plate 404 will expand through the rotating end 405. By setting the sizes of the connecting hole 403 and the clamping plate 404, the movable range of the clamping block is limited through the connecting hole 403, so that it clamps the protruding block 305 of the connecting column 304. When the connecting piece 300 needs to be disassembled, the connecting column 304 is withdrawn from the connecting hole 403 by rotating the arc blade 303 in the opposite direction, and the arc blade 303 is separated from the extension plate 401 through the clamping hole 402, which is convenient for disassembly and maintenance.

[0028] In an embodiment of the present invention, a cavity for installing electronic components is opened inside the steel column 400 and the rotating column 301. Electrical components connected to the three-dimensional mesh structure of the Ni-Ti alloy wire are arranged inside the steel column 400 and the rotating column 301. The electrical components include a power supply, a wire, a switch, a fuse and a temperature sensor. The power supply is a micro-switch power supply, the wire is a silicone wire, and the switch is a micro-switch. A fuse with a suitable rated current is selected to protect the circuit from overcurrent damage. The fuse is connected in series in the circuit and can be installed near the power supply or in the wire channel. The positive pole of the power supply is connected to one end of the switch through the wire, and welding or crimping is used to ensure a firm connection. The other end of the switch is connected to one end of the fuse, and the other end of the fuse is connected to one end of the three-dimensional mesh structure of the Ni-Ti alloy wire. The other end of the three-dimensional mesh structure of the Ni-Ti alloy wire is connected to the output end of the controller, and the input end of the controller is connected to the temperature sensor. The other end of the temperature sensor is connected to the negative pole of the power supply to form a loop.

[0029] In an embodiment of the present invention, the prediction and analysis module 505 arranges strain sensors, such as strain gauges, fiber Bragg grating sensors, etc., at key positions of the steel structure. The sensors monitor the strain changes of the structure in real time and transmit the data to the monitoring platform 500, cleans the collected raw data, removes noise and abnormal values, etc., corrects the sensor data to ensure the accuracy and consistency of the data, and interpolates the data as needed to obtain denser data points. According to the sensor data, the strain value of each monitoring point is calculated, the distribution of the strain in the structure is analyzed, and the high strain area is identified. The structure is divided into multiple grid units, each unit corresponds to a strain value, and each grid unit is mapped to a different color according to the size of the strain value to form a strain cloud map. The strain cloud map is generated using professional visualization software, and the generated strain cloud map is optimized, such as adjusting the color mapping, adding annotations, etc., to improve Readability: Output the strain cloud map as a picture or video format for easy viewing and analysis. Use a convolutional neural network to perform real-time analysis on the input strain cloud map. The convolutional neural network automatically extracts features from the image, such as stress concentration areas, deformation patterns, etc. The analyzed data is further analyzed by a deep learning model. The model can perform feature extraction, pattern recognition and predictive analysis, and output analysis results, such as structural status assessment, potential risk prediction, etc. The results are displayed in a visual manner for easy understanding and decision-making. Based on historical data and real-time monitoring data, trend prediction is performed to predict future structural status changes and potential risks. Decision support suggestions based on predictive analysis are provided, including maintenance strategies, reinforcement measures, usage restrictions, etc. The effect of the decision after implementation is fed back to the system, and the predictive analysis module 505 and the digital twin model are optimized to form a closed-loop control to continuously improve the accuracy of structural health monitoring and predictive analysis.

[0030] In the embodiment of the present invention, the detailed steps of positioning by the positioning module 502 include: Step a: According to the steel structure design drawings, determine the key connection points where the chip needs to be implanted, use special tools to implant the diamond NV color center chip into the steel structure, ensure that the chip is tightly combined with the steel structure, use epoxy resin or other fixing materials to fix the chip and protect it to prevent damage during construction. Before implanting the chip, calibrate the geomagnetic field to ensure the accuracy of the positioning data; Step b, arranging UWB ultra-wideband devices around the structure to form a positioning network covering the entire structure, connecting the UWB devices to the monitoring platform 500, and debugging to ensure stable data transmission; Step c, starting the diamond NV color center chip, monitoring the geomagnetic field disturbance in real time, and transmitting the positioning data to the monitoring platform 500 in real time through the UWB technology. The monitoring platform 500 stores, processes and analyzes the positioning data to generate spatial positioning information; The startup of diamond includes: ensuring that the diamond NV color center chip, laser equipment, microwave source, photodetector and monitoring platform 500 and other equipment are correctly connected and in good working condition, turning on the laser equipment, adjusting the laser parameters (such as wavelength, power, etc.) to match the excitation requirements of the diamond NV color center, focusing the laser on the diamond NV color center chip, exciting the NV color center, starting the microwave source, adjusting the microwave frequency to the resonant frequency of the NV color center, applying the microwave signal to the diamond NV color center chip through the microwave antenna to realize the quantum state manipulation of the NV color center, using the photodetector to collect the photons emitted by the NV color center, converting the collected photon signals into electrical signals, and performing The monitoring platform 500 records the output signal of the photoelectric detector in real time after amplification and filtering, and processes the collected data to extract useful geomagnetic field disturbance information and positioning information. Considering the material characteristics of the steel structure, the laser equipment, microwave source and photoelectric detector all need to make specific parameter adjustments, such as selecting a shorter wavelength for the laser equipment and increasing the laser frequency. The communication and data transmission of the chips between the layers of the multi-layer steel structure are realized through wireless communication technology, and signal repeaters are set in the multi-layer structure to enhance the transmission distance and penetration ability of laser, microwave and photoelectric signals. The time division multiplexing technology is used to start the chips of different layers at different time points to avoid signal interference. The detailed steps of establishing the distributed monitoring network 503 module include: Use a spraying device to evenly spray graphene conductive ink on the surface of the steel structure. After spraying, wait for the ink to dry to form a stable conductive layer, and install quantum chips at all key connection nodes of the steel structure. Use appropriate fixing materials (such as epoxy resin) to connect the quantum chip to the monitoring network formed by the graphene conductive ink. Apply a thin layer of conductive glue or conductive silver paste on the signal output end of the quantum chip to enhance the stability of signal transmission. Apply graphene conductive ink near the signal output end of the quantum chip to form a conductive circuit to ensure that the graphene conductive ink is in good contact with the conductive glue or conductive silver paste at the signal output end of the quantum chip. Extend the conductive circuit formed by the graphene conductive ink to the input end of the monitoring network to ensure that the arrangement of the quantum chip can cover the entire structure to form a complete magnetic field network. Connect the quantum chips wirelessly to form a distributed magnetic field network. The quantum chips generate distributed magnetic fields through interaction, and reflect the state changes of the steel structure through the magnetic field strength and distribution. The magnetic field data is collected in real time through the quantum chip, and processed and analyzed through the digital twin module 504 and the prediction analysis module 505, and the state of the steel structure is evaluated based on the magnetic field strength and distribution. Example

[0031] See attached Figure 7 As shown, an embodiment of the present invention further provides a method for a steel structure modular horizontal connection system based on intelligent monitoring, comprising the following steps: S1, pre-embed the three-dimensional mesh structure made of Ni-Ti alloy wire into the connection surface of the extension plate 401 and the arc blade 303, install the temperature sensor at a suitable position and connect it to the controller, spray graphene conductive ink on the surface of the steel column 400 and the connection block 100, install the connector 300 and the support 200 in the connection block 100, align the steel column 400 with the connection block 100, connect the steel structure, insert the extension plate 401 into the connection block 100, and start the motor 302 , the rotating column 301 drives the arc blade 303 to rotate, and the arc blade 303 passes through the extension plate 401 through the clamping hole 402, and at the same time, the protruding block 305 on the connecting column 304 is clamped into the connecting hole 403 of the extension plate 401. When it is necessary to disassemble the connecting block 100, the arc blade 303 is rotated in the opposite direction by the motor 302, so that the connecting column 304 is pulled out of the connecting hole 403, and the arc blade 303 is separated from the extension plate 401 through the clamping hole 402, and the alloy wire is gradually cooled and restored to its original state; S2, at the same time, the controller closes the switch, starts the power supply, starts heating the alloy wire, and monitors the temperature of the alloy wire in real time through the temperature sensor. When the temperature reaches 40°C, the controller adjusts the power output to keep the temperature stable. After being heated to the phase transition temperature, the alloy wire contracts, and the extension plate 401 and the arc blade 303 are adaptively pressed. Among them, the temperature control strategy is as follows: first increase the temperature of the alloy wire to a temperature close to the phase change temperature, for example, from room temperature to 35°C, slow down the heating rate to more finely control the temperature to avoid exceeding the phase change temperature, for example, halve the rate of increasing from 35°C to 40°C, keep the temperature stable for a period of time, for example, 2-5 minutes, to ensure that the alloy wire is fully contracted and the adaptive compression is completed. As needed, the temperature can be gradually lowered to a safe level, or the phase change temperature can be maintained to continuously monitor the connection status. The temperature of the alloy wire is monitored in real time by a temperature sensor, and the data is transmitted to a controller. The controller adjusts the power output according to the real-time temperature data to keep the temperature stable near the phase change temperature. Set a maximum temperature limit, for example, 41°C. Once the temperature exceeds this limit, immediately cut off the power supply and issue an alarm. Set a minimum temperature limit, for example, 38°C. Once the temperature is lower than this limit, increase the power output to increase the temperature. Use a controllable power supply such as a thyristor or a solid-state relay to achieve fine power regulation. According to temperature feedback, a PID control algorithm is used to achieve fast and stable temperature control. S3, when the connection block 100 is connected to the steel column 400, the connection status of the connection piece 300 is monitored in real time through the sensing module 501, the blade position is detected through the Hall sensor 5011, the relative position between the arc blade 303 and the extension plate 401 is continuously monitored, and a digital signal is output to indicate whether the blade is in place. The pressure sensor measures the pressure distribution on the contact surface between the arc blade 303 and the extension plate 401 in real time, converts it into an electrical signal and transmits it to the monitoring platform 500, the laser excites the quantum chip to generate NV color center light emission, the photodetector collects the photon signal, converts it into an electrical signal to indicate the change of the geomagnetic field, and uses the known geomagnetic field model and the measured geomagnetic field disturbance data to calculate the position of the steel structure through a mathematical algorithm, so as to adjust the connection position of the steel structure; S4, transmitting the sensor data to the monitoring platform 500 through wireless communication technology, preprocessing the data, and updating the digital twin model of the steel structure in real time based on the collected data to reflect the current state and deformation of the structure, analyzing the stress, strain, displacement and other indicators of the structure according to the digital twin model, and evaluating the health state and remaining life of the structure; S5, inputs the preprocessed strain data, extracts features through convolutional neural network, outputs strain cloud map, displays the structural strain distribution, uses machine learning algorithm to predict the probability of connection failure based on historical data and current status, outputs the failure probability, analyzes the trend of structural status change, predicts risks, and performs corresponding processing according to the predicted structure; S6, when the monitoring indicators exceed the preset threshold, it automatically issues warning information, generates decision-making suggestions such as maintenance strategies, reinforcement measures and usage restrictions based on the prediction analysis results, displays real-time monitoring data through a visual interface, and provides a variety of charts and views to facilitate users to intuitively understand the structural status.

[0032] It should be noted that S1 is the basic installation step and needs to be completed first. S2 is carried out after S1 is completed, but heating and temperature monitoring are carried out synchronously. The sensing module 501 monitoring and Hall sensor 5011 detection in S3 are carried out synchronously with S1 to jointly provide information on the connection status. The data transmission and digital twin model update of S4 are carried out synchronously with S1 to reflect the structural status in real time. The data preprocessing and feature extraction of S5 are carried out after S4 is completed, with preprocessing first and then feature extraction. Predictive analysis is a continuous process based on real-time data. The early warning and decision recommendation generation of S6 is based on the results of S5, but real-time data display is continuous.
