Description

Technical Field

[0001] This utility model relates to the field of roadbed monitoring technology, and in particular to a real-time monitoring device for uneven deformation of roadbed based on multi-directional angle sensing. Background Technology

[0002] In road engineering, uneven deformation of the roadbed is a significant factor affecting the stability and service life of the road structure. Traditional roadbed deformation monitoring schemes typically rely on sensors in a single direction or manual measurements, making it difficult to comprehensively capture the uneven deformation of the roadbed in three-dimensional space. Furthermore, existing roadbed deformation monitoring schemes often have low data acquisition efficiency, making real-time monitoring and early warning difficult. This results in the inability to take timely measures when roadbed deformation reaches a dangerous level, potentially seriously impacting the safety and stability of the road structure. Typically, sensors in a single direction can only monitor deformation in a specific direction, failing to reflect the complex deformation of the roadbed in three-dimensional space. Additionally, traditional data acquisition and transmission methods are inefficient, making it difficult to meet the needs of real-time monitoring and timely detection and response to uneven roadbed deformation. Therefore, there is an urgent need for a scheme that can comprehensively, in real-time, and reliably monitor uneven roadbed deformation to improve monitoring accuracy and efficiency, ensuring the safety and reliability of road engineering projects.

[0028] like Figure 1 As shown, an embodiment of this utility model provides a real-time monitoring device for uneven deformation of roadbed based on multi-directional angle sensing, including a three-dimensional crossbar 10, multiple tilt sensors 20, a data transmission line 30, and a data acquisition instrument 40. Meanwhile, as... Figure 2As shown, the three-dimensional cross frame 10 is embedded in the soil and consists of three steel bars intersecting in pairs, for example, at a 90° angle, and spatially distributed along the XYZ directions, thus allowing it to deform synchronously with the soil. Three tilt sensors 20 are installed inside each of the three steel bars, enabling real-time sensing of angle changes in the corresponding steel bars. A data transmission line 30 connects the tilt sensors 20 to the data acquisition unit 40, using RS485 or CAN bus protocols to achieve synchronous transmission of multi-channel data. The data acquisition unit 40 can connect wirelessly to other terminal devices 50, which can receive, display, and store data in real time, and also facilitate the setting of an early warning function for uneven settlement exceeding limits.

[0029] As described above, the real-time monitoring device for uneven roadbed deformation based on multi-directional angle sensing provided in this embodiment can comprehensively capture the uneven deformation of the roadbed in three-dimensional space. The three-dimensional cross-frame 10 has three steel bars distributed along the XYZ directions. When the angle of the corresponding steel bar changes, it can be detected by the internal tilt sensor 20. After the data is transmitted to the data acquisition unit 40, the corresponding parameters can be calculated using the system's built-in algorithm to reflect the uneven deformation of the roadbed in three-dimensional space. Therefore, the real-time monitoring device for uneven roadbed deformation based on multi-directional angle sensing provided in this embodiment is mainly used to monitor and upload the angle change data of the roadbed in three directions in real time.

[0030] At the same time, such as Figure 2 As shown, in a preferred embodiment, the outer cross-section of the steel bars is rectangular with a hollow interior to facilitate interconnection and installation of the tilt sensor 20. In one specific embodiment, the steel bars are directly fixed by welding. Taking the first steel bar 11, the second steel bar 12, and the third steel bar 13 as an example, the lower surface of the second steel bar 12 is welded to the upper surface of the first steel bar 11, and the side surface of the third steel bar 13 is welded to the side surface of the first steel bar 11, forming an integral three-dimensional cross frame 10. When buried in the roadbed, it can reliably detect uneven deformation in three-dimensional space.

[0031] At the same time, such as Figure 3 As shown, in another specific embodiment, the steel bars can also be detachably connected by bolts. For example, threaded holes can be provided on the first steel bar 11, and connecting lugs 14 can be provided at corresponding positions on the second steel bar 12 and the third steel bar 13. Through holes are also provided on the connecting lugs 14 to allow for detachable connection of the second steel bar 12 to the first steel bar 11 and the third steel bar 13 to the first steel bar 11 using bolts. This method facilitates assembly and disassembly, and is beneficial for recycling and reuse.

[0032] In this embodiment, each of the three steel bars has a detachable end cap 15, which facilitates the installation and removal of the tilt sensor 20. Additionally, the end cap 15 has an end hole 16 for leading the data transmission line 30 connecting the tilt sensor 20 from the steel bar to the data acquisition instrument 40. The data transmission line 30 uses RS485 or CAN bus protocols to achieve synchronous transmission of multi-channel data, ensuring efficient and accurate data acquisition.

[0033] In this embodiment, the data acquisition device 40 may be equipped with a wireless communication module for transmitting data to other terminal devices 50. The terminal device 50 may include a computer, smartphone, or tablet computer, which has data processing and visualization display functions, and can set multi-level warning thresholds. When the deformation of a certain area exceeds the safe range, it can issue a warning signal in a timely manner.

[0034] When using the real-time monitoring device for uneven deformation of roadbed based on multi-directional angle sensing provided in this embodiment, the following steps are included:

[0035] S1, embed the three-dimensional cross frame 10 in the roadbed, ensuring that the three steel bars are embedded in the soil along the XYZ directions respectively;

[0036] S2: Install tilt sensors 20 inside each steel bar to ensure that the tilt sensors 20 can monitor the angle changes of the corresponding steel bar in real time;

[0037] S3: Connect the tilt sensor 20 to the data acquisition instrument 40 via the data transmission line 30;

[0038] S4: Install the data acquisition device 40 in the monitoring area, debug the signal, and ensure that the data acquisition device 40 and the terminal device 50 can communicate wirelessly normally.

[0039] S5: Set the warning threshold for terminal device 50 and start real-time monitoring of uneven deformation of the roadbed.

[0040] In summary, the real-time monitoring device for uneven roadbed deformation based on multi-directional angle sensing provided in this embodiment, based on the setting of the three-dimensional cross frame 10 and the built-in tilt sensor 20, can comprehensively sense the uneven deformation of the roadbed in the XYZ directions, realize accurate monitoring of multi-directional angles, and has a simple structure and is easy to install and disassemble. With the data acquisition instrument 40, it can monitor the amount of uneven deformation of the roadbed in real time and transmit the data to the terminal device 50 through wireless communication, so as to realize the real-time display and storage of data. In addition, the terminal device 50 can set multi-level early warning thresholds to promptly detect abnormal uneven settlement and issue early warning signals, thereby improving the safety and reliability of the project.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
