Data logger Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] like Figure 1 As shown, the structural strength assessment and testing device for a building according to this application includes a loading unit 1, a loading plate 2, a stress transfer assembly 3, and a support frame. This design provides a multi-directional force application mechanism for applying variable loads to different locations of the building structure and ensuring that these forces are stably and accurately distributed to the tested object. The individual components are described in detail below.

[0027] Loading unit 1 is the core component for achieving the above functions. It is installed on the top layer of the entire device and connected to the loading plate 2 below via a mechanical interface. Loading unit 1 itself consists of multiple cooperating components and employs an adjustable tilt angle structure. For example, its tilt angle can be changed using a series of gear transmissions or a hydraulic system to adapt to different test conditions. It can adjust the pressure direction according to preset parameters to simulate complex load conditions in real-world environments. This part includes multiple spring loading modules 11 to simulate pressure loads ranging from concentrated to widely distributed, making the testing more closely resemble actual usage environments.

[0028] The loading plate 2 is located below the loading unit 1 and directly contacts the area of ​​the building to be tested. The loading plate 2 is designed to be made of a sturdy yet flexible flat sheet material. It can withstand and evenly distribute the force transmitted from the loading unit 1, then disperse and apply it evenly to the surface to be tested. For example, by placing an elastic buffer pad on its back, surface flatness is ensured during force application, and the problem of excessive local pressure is avoided.

[0029] The stress transmission component 3 is fixedly installed at the bottom of the loading plate 2 and extends through to the contact surface of the part being inspected. Its main function is to perform secondary equalization of the applied force before transmitting it to the building structure, while preventing any deformation error from affecting the accuracy of the results. To achieve this goal, the component is equipped with precision guide rails and high-strength wear-resistant materials to form a stable connection channel to ensure the consistency and sensitivity of signal transmission.

[0030] All other components of the entire testing system are ultimately and securely fixed within a support frame that serves as the overall platform for the device. This creates a stable mechanical support system, ensuring the safety and accuracy of all operations. The support frame has sufficient space to support the other components and is equipped with multiple fastening points for assembly, giving the entire frame strong stability and good vibration resistance, ensuring that all tests can be completed smoothly without interference.

[0031] This feature effectively solves the problem of designing more efficient loading mechanisms, mainly by improving both flexibility and accuracy through an integrated hardware solution. On the one hand, force transmission experiments at multiple angles can be completed on the same test platform without the need for additional external facilities; on the other hand, the built-in spring loading module 11 and its matching fast-release structure enable rapid and flexible setting of various load combinations, and facilitate easy verification and adjustment at any time, greatly saving debugging time and increasing the safety and reliability of the testing process.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the loading unit 1 of the building structure strength assessment and testing device of this application is a multi-directional force application mechanism, used to apply variable loads to different locations of the building structure. The loading unit 1 includes a set of electrically adjustable devices 5, which are located inside the loading unit 1 and tightly integrated with its mechanical structure to achieve angle adjustment without changing the dimensions of the supporting frame. By adjusting the settings of the electrically adjustable devices 5, the relative tilt angle between the loading unit 1 and the horizontal plane can be precisely controlled. This feature allows the device to provide loads in multiple directions at the same location, adapting to various testing needs.

[0033] During operation, the electric adjustment device 5 consists of several motors and matching transmission mechanisms. These components are connected to the main load-bearing component of the loading unit 1 via precision gears and lead screws. The drive unit of the electric adjustment device 5 is fixed to one side of the support frame and ensures that the loading unit 1 moves precisely along the required path via guide rails or other similar structures, thereby achieving the ideal tilt angle setting value.

[0034] Specifically, in one embodiment, the device is implemented by sending a command to the electric adjustment device 5 through the control system, causing it to drive internal transmission components such as screws or chains to tilt the loading unit 1 as a whole. This design allows technicians to easily set different tilt angle parameters during the test preparation phase and then lock them in place to ensure the consistency and accuracy of the loading angle during the experiment. Furthermore, to ensure stability during angle changes, the electric adjustment device 5 is also equipped with a self-locking mechanism to prevent angle deviation caused by external factors after the target tilt angle is reached.

[0035] like Figure 4 As shown, in one embodiment, the loading unit 1 of the building structure strength assessment and testing device of this application is equipped with a unique quick-release structure 12. This quick-release structure 12 consists of an electromagnetic drive locking device. The electromagnetic plate is built into the spring loading module 11 in the multi-directional force application mechanism, and maintains the entire array of spring loading modules 11 in a compressed state by adsorbing its movable arm. When the load needs to be released, the electromagnet stops supplying power, allowing the originally fixed movable arm to complete the decompression process in a very short time, thereby efficiently and flexibly switching between different load configurations.

[0036] Specifically, this electromagnetic drive locking device comprises two main parts: first, an internally mounted electromagnetic plate and its associated electrical control system, used to control changes in the electromagnetic field to achieve locking and unlocking functions; the other crucial part is a movable arm made of special materials that can shift with changes in the magnetic field. This special installation method not only ensures that the movable arm remains relatively stable when not affected by current, but also ensures that it quickly disengages from its constrained position upon receiving a power-off command, thereby propelling the entire array to achieve the intended power transmission task. For example, during implementation, through fine-tuning of the electromagnetic system built into the loading module array and precise time-delay design, it is possible to achieve an almost instantaneous transition from a secured state to a freely released state without the aid of external force. This mechanical and electronic collaborative working mechanism greatly enhances the ease of operation and flexibility of the testing device.

[0037] like Figure 4 As shown, in one embodiment, each spring loading module 11 of the structural strength assessment and testing device of this application is equipped with an independent pressure sensor 6, which can monitor and provide feedback on the stress distribution at each point in real time, and is connected to the control system to optimize the simulation effect. This design ensures accurate monitoring of stress at multiple points, thereby providing comprehensive and detailed force distribution data.

[0038] In practical applications, spring loading modules 11 are distributed around the multi-directional force application mechanism of loading unit 1 to simulate real-world force conditions. Each spring loading module 11 contains a pressure sensor 6 located near the spring loading mechanism to directly sense the force changes generated. These sensors are connected to the control system via cables to achieve real-time data acquisition and transmission. This design allows users to dynamically adjust and monitor the specific loads at different test points, ensuring the uniformity and controllability of force in each test area during loading. The signals provided by the pressure sensors 6 are transmitted to the control center for analysis to verify and record the true stress state of each test. This structure not only improves detection accuracy but also enhances the application range and adaptability of the device.

[0039] Specifically, each spring loading module 11 has an integrated independent pressure sensor 6 installed near the point of force application to capture accurate pressure values. These pressure sensors 6 are encased in a flexible material protective layer, which protects against external interference without affecting the normal mechanical performance of the spring. Simultaneously, all sensor data interfaces communicate with the main control system via cable or wirelessly, ensuring stable and reliable data transmission to a computer or other processing units for further analysis. This arrangement enables the entire system to operate efficiently in complex and variable working environments, meeting the demands of demanding testing tasks.

[0040] like Figure 3 As shown, in one embodiment, the loading plate 2 of the structural strength assessment and testing device of this application is covered with a uniformly distributed pressure-conducting membrane 7. This membrane is designed to improve adaptability to non-flat surfaces, ensuring that force is distributed more evenly to the surface of the tested structure, avoiding localized stress concentration caused by surface unevenness. The pressure-conducting membrane 7 has good elastic deformation characteristics, maintaining relatively stable and reliable force transmission characteristics even when the contact surface shape changes significantly. Furthermore, this membrane can effectively reduce force concentration caused by localized protrusions or depressions on the contact surface, further reducing the possibility of data deviation.

[0041] The application of the pressure-conducting membrane 7 significantly improves the device's performance on complex surfaces. Its high elasticity and compliance maintain constant pressure transmission performance on various test surfaces, resulting in more accurate and reliable test results. Specifically, the membrane adheres tightly to the surface of the loading plate 2 and maintains good contact quality throughout the measurement process. This improvement is crucial for handling diverse surface morphologies in various practical engineering environments and expands the applicability of this device.

[0042] For example, the pressure-conducting membrane 7 can be manufactured using a highly elastic, flexible material. This membrane can be firmly attached to the entire surface area of ​​the bottom of the loading plate 2 using adhesives or other suitable methods, ensuring its flatness and absence of bubbles or wrinkles that could affect its performance. Once installed, the pressure-conducting membrane 7 works in conjunction with the loading plate 2, maintaining stability under pressure applied at any tilt angle and evenly distributing the force to the object being tested. This approach does not compromise the compact layout of the original system while enhancing the overall performance of the device, meeting testing requirements under a wider range of conditions.

[0043] like Figure 3 As shown, in one embodiment, the loading plate 2 of the structural strength assessment and testing device of this application is provided with a buffer frame 8 around its perimeter to effectively prevent damage or displacement caused by edge stress during structural strength testing. This design not only improves the safety of the tested object but also ensures consistent and uniform stress distribution throughout the testing process. Since different parts of a building may be subjected to complex mechanical forces in practical applications, the edge areas are particularly vulnerable and easily damaged. This device, through its special design, avoids such problems, thereby providing more reliable experimental data support. Therefore, the design of this buffer frame 8 provides an important guarantee for achieving accurate and reliable building structural testing, enhancing the effectiveness and safety of the entire testing system.

[0044] Structurally, the buffer frame 8 is located at the outer edge of the loading plate 2 and is tightly connected to it. It is made of a material with certain elastic deformation characteristics, such as a high-toughness polymer, capable of withstanding significant deformation without breakage or failure. To adapt to different testing requirements, the buffer frame 8 has multiple spaced elastic units inside, allowing it to expand and contract accordingly with changes in the pressure applied to it, maintaining good buffering performance without hindering load transfer during testing. Furthermore, by adjusting the number, size, and arrangement of these elastic units, the structure can be made more adaptable to various sizes of building components under test. For example, in practice, the optimal testing conditions can be achieved by changing the configuration of the embedded springs or other elastic elements.

[0045] like Figure 3As shown, in one embodiment, a transmission plate 9, made of flexible material, is provided on the stress transmission component 3 of a building structure strength assessment and testing device of this application. The transmission plate 9 is directly installed at the contact surface of the stress transmission component 3 and covers the contact surface. This structure allows the transmission plate 9 to smoothly transmit force under complex torque paths, thereby ensuring that the force can be transmitted to the target test area without distortion. The presence of the transmission plate 9 not only optimizes the force transmission process but also maintains the compact design of the device. In addition, the transmission plate 9 and the stress transmission component 3 are firmly bonded together by a high-strength adhesive or embedded connectors to ensure a tight bond between the two, thereby maintaining long-term stability and reliability.

[0046] For example, in practical applications, when the multi-directional loading unit 1 applies force to the main structure of a building, this force is first evenly distributed to the surface of the loading plate 2, and then further distributed by the stress transmission component 3 connected below the loading plate 2. At this point, the role of the transmission plate 9 becomes particularly crucial—it can flexibly respond to and adapt to changes in the shape and angle of different objects being measured, thereby ensuring accurate stress transmission even in non-planar or highly curved areas, while avoiding force distortion caused by rigid contact. This design allows the device to complete complex torque path transmission tasks while maintaining a compact structure.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the support frame design of the structural strength assessment and testing device of this application is specifically optimized to improve the flexibility of on-site application. The device features a bottom roller movement mechanism and positioning screws 10, facilitating the movement and fixation of the equipment on the construction site. Specifically, the bottom roller movement mechanism is located at the bottom edge of the support frame, allowing the equipment to move smoothly on flat or uneven ground. The positioning screws 10 are distributed and installed near the four corners of the support frame 4, and can be tightened or loosened to ensure the device is securely stopped at the test point and maintain operational stability.

[0048] In addition, the support frame is equipped with fixing plates 13. These fixing plates 13 are securely installed on the top plane of the frame and can be connected to the external carrier vehicle by bolts or other fasteners, serving to absorb shock and secure the equipment during transportation. Once the equipment is placed at the test point, the fixing plates 13 are removed, allowing other working components to be freely arranged according to operational requirements.

[0049] For example, during the manufacturing process, high-quality materials can be used to create a robust support frame, and rollers with locking functions can be fixed to designated areas by welding or screws to ensure reliability and safety. The positioning screw 10 is made of corrosion-resistant metal and precision-machined to ensure accuracy. The fixing plate 13 also needs to undergo strict quality inspection, and nuts, screws, and other accessories are made of high-tensile-strength and wear-resistant materials to achieve a good fixing effect.

[0050] like Figure 2 As shown, in one embodiment, the support frame of the structural strength assessment and testing device of this application integrates an automatic leveling calibration system 14, which enables real-time attitude adjustment. This design ensures the stability of the equipment during operation and avoids measurement errors caused by attitude tilt due to external factors. Specifically, a highly accurate and responsive automatic calibration system is installed on the support frame, which can continuously monitor and fine-tune the angle of the device during operation, thereby ensuring the authenticity and reliability of the test data.

[0051] For example, the automatic leveling calibration system 14 mainly consists of three parts: a sensor, a control circuit, and an adjustment mechanism. The sensor monitors whether the device is tilted and transmits this information to the control circuit; the control circuit then issues commands to the adjustment mechanism based on the feedback signals to correct the angle deviation and restore it to the set value. This automatic calibration function works independently and does not require additional operational intervention to maintain the stability of the system's attitude.

[0052] Specifically, the components of the automatic leveling calibration system 14 are compactly mounted at the bottom of the support frame near the edge, with sensors closely fitted inside the frame plane for more accurate detection of subtle changes. The adjustment mechanism, connected to the control system via an electric actuator or hydraulic transmission, responds quickly to adjustment commands and performs corrective actions, making the entire process fast and efficient. High-strength connectors such as bolts ensure robustness and reliability between components, while also providing sufficient flexibility to support smooth motion transitions, thus meeting the precise positioning requirements under various working conditions.

[0053] like Figure 2 As shown, in one embodiment, the overall device of the building structure strength assessment and testing device of this application is equipped with a built-in data logger 15. The data logger 15 is disposed inside the support frame and connected to various key components, including the loading unit 1, the loading plate 2, and the stress transfer assembly 3. The built-in data logger 15 is used to automatically collect and store key parameters in each experiment, including but not limited to the loading force value, application time, and stress distribution, ensuring that subsequent data analysis has complete original information support.

[0054] Specifically, the built-in data logger 15 consists of a high-speed processing unit and a non-volatile memory chip. The high-speed processing unit can collect and process data signals from the sensors in real time, and then quickly transmit these processed results to the non-volatile memory chip for secure storage. This design not only ensures the continuity and accuracy of experimental data, but also lays a solid foundation for future upgrades and technological research.

[0055] For example, in terms of technical implementation, the built-in data logger 15 can directly acquire the changes in relevant physical quantities at different testing stages through various types of sensor interfaces preset in the loading unit 1, loading plate 2, and stress transfer assembly 3. Each time the detection device is turned on, the sensors self-check and initialize the communication protocol, and begin sending various parameter information generated during the experiment to the data logger 15 at a predetermined frequency for storage, so that users can query and use it later. This system simplifies operation and greatly improves the convenience of experimental data management and subsequent analysis.

[0056] In practical operation, when this device is used, variable loads can be applied to different locations on the main structure of a building via the loading unit 1. First, the device is moved to the appropriate location on the building to be tested, ensuring the support frame is stable to provide a solid foundation platform. After the loading unit 1 is set to the required tilt angle, pressure transmission paths at different angles can be achieved. According to the test requirements, the array of spring loading modules 11 is adjusted to simulate multi-point distributed or concentrated load conditions. Then, the loading unit 1 is activated to apply the predetermined load. During this process, the loading plate 2 evenly distributes the force from the loading unit 1 to the surface of the building structure under test, while the stress transfer component 3 ensures that this force is transmitted to the main structure of the building without distortion and smoothly. If a rapid adjustment of the load configuration is required, it can be modified and re-stabilized via the quick-release structure 12, making the entire process more flexible and efficient. After the test is completed, the device can be easily unloaded or its settings changed via the quick-release structure 12 to prepare for the next test.

[0057] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
