[0002] Ancient building deformation monitoring involves long-term, repeated observation of changes in the spatial location of ancient buildings to assess their structural stability and safety, and to prevent structural damage caused by natural weathering, geological activity, or human factors. It is a core technical means of cultural heritage protection. Ancient building deformation monitoring is shifting from "passive restoration" to "active prevention," and through technological innovation and data-driven approaches, it aims to achieve the long-term safe preservation and scientific utilization of cultural heritage.

[0003] Currently, existing technologies for monitoring deformation of ancient buildings mostly employ multi-sensor integrated nodes. These nodes physically integrate or fuse data from various types of sensors, such as displacement, strain, environmental, and image sensors, into a single node, constructing an integrated system of "sensing-transmission-analysis-early warning." However, existing multi-sensor integrated nodes are fixedly installed at their operating locations, and to ensure monitoring accuracy, multiple nodes are installed on the same vertical plane, resulting in very high costs for monitoring deformation of ancient buildings. Therefore, this paper proposes an IoT multi-sensor integrated node device for monitoring deformation of ancient buildings to address these issues. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses an Internet of Things (IoT) multi-sensor integrated node device for monitoring deformation of ancient buildings. (Refer to...) Figure 1 , Figure 2 and Figure 3An IoT multi-sensor integrated node device for monitoring deformation of ancient buildings includes two base frames 1. A support rod 2 is fixedly connected to one side of the two base frames 1. A node body 3 is slidably connected to the surface of the support rod 2. An adjustment component 4 is fixedly installed on the top of one of the base frames 1. The adjustment component 4 works in conjunction with the node body 3. A support component 5 is provided on one side of the two base frames 1. The support component 5 works in conjunction with the node body 3.

[0024] The node body 3 consists of a shell, a sensing unit, a processing unit, and a transmission unit;

[0025] The sensing unit includes a geometric deformation sensor, an environmental parameter sensor, and an image and defect detection sensor. The geometric deformation sensor can be a GNSS module, inclinometer, fiber optic strain sensor, or laser rangefinder, as needed, to monitor the deformation of the ancient building. The environmental parameter sensor can be a temperature and humidity sensor, an anemometer, or a groundwater level monitor, as needed, to monitor the environmental parameters of the ancient building. The image and defect detection sensor can be an industrial camera or an infrared thermal imager, to monitor defects in the ancient building.

[0026] The processing unit includes a main control chip, a data processing module, and an edge decision module. The main control chip uses a low-power microprocessor with an integrated ARM Cortex-M4 core, supporting floating-point operations and hardware encryption. The data processing module includes data preprocessing, feature extraction, and machine learning inference. Data preprocessing is used to perform filtering, noise reduction, and data alignment to reduce the amount of data transmitted. The edge decision module is based on a rule engine or expert system to implement local early warning logic and reduce cloud latency.

[0027] The transmission unit includes a low-power wide area network (LPWAN), a protocol stack, and data encryption. The LPWAN is a 5G module that provides high-speed data transmission capabilities, suitable for scenarios requiring real-time video monitoring or high-precision deformation field reconstruction, and transmits the data to the cloud platform. Data encryption: AES-256 encryption is used for transmission, combined with a TLS / SSL secure channel to ensure the confidentiality and integrity of the data during transmission.

[0028] The adjustment component 4 includes a motor 41, which is fixedly installed on the top of one of the base frames 1. The output end of the motor 41 is fixedly connected to a rotating shaft 42. A take-up roller 43 is fixedly sleeved on the surface of the rotating shaft 42. A pull rope 44 is wound around the surface of the take-up roller 43. One end of the pull rope 44 passes through one of the base frames 1 and is slidably connected to the inner cavity of one of the base frames 1. A connecting frame 45 is fixedly connected to one side of the node body 3. One end of the pull rope 44 is fixedly connected to the top of the connecting frame 45.

[0029] The motor 41 drives the rotating shaft 42 to rotate, which in turn drives the winding roller 43 to rotate. The winding roller 43 then winds up and unwinds the pull rope 44. By winding up or unwinding the pull rope 44, the pull rope 44 drives the connecting frame 45 to move longitudinally. The support rod 2 stabilizes the position of the connecting frame 45, allowing the connecting frame 45 to drive the node body 3 to move longitudinally. This adjusts the height of the node body 3, enabling the node body 3 to be monitored from different heights. During the adjustment of the node body 3, the support component 5 prevents the node body 3 from being damaged by a rigid collision with the base frame 1.

[0030] Reference Figure 2 A positioning block 4201 is fixedly installed at one end of the rotating shaft 42, and a positioning frame 4202 is fixedly installed on the top of one of the base frames 1. The positioning block 4201 is rotatably connected to the inside of the positioning frame 4202. By rotatably connecting the positioning block 4201 to the inside of the positioning frame 4202, the positioning frame 4202 can effectively stabilize the position of the rotating shaft 42 and prevent the rotating shaft 42 from tilting or shifting, which would affect the position of the take-up roller 43.

[0031] Reference Figure 3 A first connecting sleeve 4501 is fixedly connected to the surface of the connecting frame 45. The first connecting sleeve 4501 is slidably sleeved on the surface of the support rod 2. By sliding the first connecting sleeve 4501 on the surface of the support rod 2, the support rod 2 is stabilized by the first connecting sleeve 4501, so as to avoid the position of the connecting frame 45 being affected by positional displacement or other situations.

[0032] Reference Figure 3 A counterweight 46 is fixedly connected to the bottom of the connecting frame 45, and a second connecting sleeve 4601 is fixedly connected to the surface of the counterweight 46. The second connecting sleeve 4601 is slidably sleeved on the surface of the support rod 2. When the pull rope 44 is released, the position of the counterweight 46 is stabilized by the second connecting sleeve 4601 to prevent the counterweight 46 from shifting position, so that the counterweight 46 can drive the connecting frame 45 to move downward, thereby allowing the node body 3 to move downward by the gravity of the counterweight 46.

[0033] Reference Figure 2The support component 5 includes two sets of springs 51, with two springs in each set. The two sets of springs 51 are fixedly connected to opposite sides of the two base frames 1. One end of each set of springs 51 is fixedly connected to a top plate 52. A rubber pad 53 is fixedly installed on the opposite side of each set of top plates 52. The rubber pad 53 is used in conjunction with the node body 3. A positioning rod 54 is fixedly connected to the opposite side of each of the two top plates 52. One end of the positioning rod 54 passes through the base frame 1 and is slidably connected to the inner cavity of the base frame 1. A support block 5 is fixedly installed on one end of the positioning rod 54. 5. The support block 55 is used in conjunction with the base frame 1. When adjusting the position of the node body 3, the support block 55 prevents the positioning rod 54 from separating from the base frame 1, so that the positioning rod 54 stabilizes the position of the top plate 52. When the node body 3 contacts the top plate 52, the rubber pad 53 can prevent the node body 3 from rigidly contacting the top plate 52, while the spring 51 can buffer the top plate 52 to prevent the node body 3 from rigidly contacting the base frame 1, thereby avoiding the collision between the node body 3 and the base frame 1 when adjusting the position of the node body 3.

[0034] Working principle: During the use of the node body 3, the motor 41 drives the rotating shaft 42 to rotate, and the positioning block 4201 is rotatably connected to the inside of the positioning frame 4202, so that the positioning frame 4202 supports and stabilizes the position of the rotating shaft 42, so that the rotating shaft 42 drives the winding roller 43 to rotate, so that the winding roller 43 plays the role of winding and releasing the pull rope 44. By winding or releasing the pull rope 44, the pull rope 44 drives the connecting frame 45 to move longitudinally, and the first connecting sleeve 4501 slides on the surface of the support rod 2, so that the support rod 2 stabilizes the position of the connecting frame 45, and the second connecting sleeve 4601 stabilizes the position of the counterweight 46. When the pull rope 44 is released, the counterweight 46 drives the node body 3 to move downward through the connecting frame 45, so that the node body 3 can be... The longitudinal displacement is used to adjust the height of the node body 3, allowing the node body 3 to be monitored from different heights. The monitored values ​​can be transmitted to the cloud platform via the transmission unit for the collection of deformation data of the ancient building. In addition, during the adjustment of the node body 3, the support block 55 prevents the positioning rod 54 from separating from the base frame 1, so as to stabilize the position of the top plate 52. When the node body 3 contacts the top plate 52, the rubber pad 53 can prevent the node body 3 from rigidly contacting the top plate 52, and the spring 51 can buffer the top plate 52 to prevent the node body 3 from rigidly contacting the base frame 1. This avoids the node body 3 from being damaged by rigid collision with the base frame 1 when adjusting the position of the node body 3.
