Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ancient building protection, in particular to a micro-environment multi-modal monitoring and on-site intervention protection system and method for ancient building wood structure. BACKGROUND

[0002] In recent years, the digital protection technology for wood structure ancient buildings has rapidly evolved from "single-point detection" to "multi-modal perception-modeling evaluation-intelligent repair" system exploration: lightning warning and active intervention, micro-deformation-hygroscopic coupling monitoring, multi-modal non-destructive testing, intelligent crack identification and three-dimensional evaluation, structure safety quantification and intelligent construction, on-site reinforcement tooling, geometric posture measurement, and digitalization of traditional measurement rules. However, the existing achievements are mostly link tools, which generally have the problems of data fragmentation, shallow fusion, insufficient on-site robustness and construction output, and are difficult to meet the requirements of "minimum intervention, reversibility, traceability" of cultural heritage and long-term operation and maintenance demands of grassroots units. Current technologies focus on single monitoring or intervention links such as lightning warning and crack identification, but fail to build a complete closed loop of "monitoring-diagnosis-decision-construction-feedback", leading to data silos and difficulties in cross-link reuse.

[0003] Therefore, the present application provides a micro-environment multi-modal monitoring and on-site intervention protection system and method for ancient building wood structure. SUMMARY

[0004] The present application aims to provide a micro-environment multi-modal monitoring and on-site intervention protection system and method for ancient building wood structure, which builds a reversible installation and minimum intervention "multi-modal monitoring-threshold triggering-on-site micro-environment intervention-retest archiving" closed-loop control scheme, and realizes early detection, early inhibition and traceability of diseases.

[0019] Further, the intervention execution module comprises a micro-dehumidification unit for reducing the humidity of the local environment, a light bacteriostatic unit for inhibiting microorganisms, and a micro-atomization cabin for pest control or bacteriostasis.

[0020] Further, the micro-dehumidification unit comprises a Peltier condenser, a moisture guide pad, or a desiccant cabin.

[0023] Further, the intervention execution module further comprises a column foot moisture-proof ventilation base, which comprises a hydrophobic ceramic ring, a ring-shaped ventilation groove, and a probe embedding position, and the column foot moisture-proof ventilation base is installed between the column foot of the wood structure and the floor.

[0024] Further, the judgment rule of the edge controller is as follows:

[0046] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0047] Please see Figures 1-3 This invention provides a technical solution: a multimodal monitoring and in-situ intervention protection system for the microenvironment of ancient wooden structures, comprising:

[0048] The data acquisition module is used to collect multimodal data of the environment surrounding the target wooden structure;

[0049] The intervention execution module is used to physically intervene and protect the microenvironment surrounding the target wooden structure, including dehumidification, microbial inhibition, and insect repellency.

[0050] The edge controller, communicatively connected to the data acquisition module and the intervention execution module, is used to receive multimodal data and perform judgment and processing on it.

[0051] When the moisture content is greater than or equal to the threshold and the temperature is within the safe range and remains within or equal to the set duration, the intervention execution module is activated to perform dehumidification.

[0052] When the VOC gas content is greater than or equal to the baseline increment threshold and the relative humidity is greater than or equal to the threshold, the intervention execution module is activated to inhibit microorganisms.

[0053] When the number of pest sound events is greater than or equal to the threshold, the intervention execution module is activated to drive away pests. The pest sound events include crack deformation vibration and pest sounds.

[0054] It should be noted that multimodal data includes the following:

[0055] Wood moisture content data: Collected by a moisture content probe, this data monitors the internal humidity level of the wood, serving as a key indicator of the risk of fungal decay and warping. This data supports threshold determination (e.g., triggering dehumidification intervention when moisture content ≥ 20%).

[0056] Surface temperature and humidity data: Collected by surface temperature and humidity sensors, providing real-time readings of ambient temperature and relative humidity. This data is used to assess microenvironment stability and, combined with moisture content data, to optimize intervention logic (e.g., high temperature and high humidity environments may accelerate fungal growth).

[0057] Thermal imaging data (optional): Acquired by a thermal imaging micro-module, this data captures the temperature distribution and abnormal hot spots in the target area through infrared imaging. It is used to assist in screening for abnormal heat and humidity (such as localized dampness at the base of columns) and to enhance the comprehensiveness of monitoring during routine inspections.

[0058] Crack activity event count data: Acquired by acoustic emission or micro-vibration sensors, this data records the frequency of acoustic events such as crack propagation or micro-deformation of wooden components. This data helps to detect potential structural safety hazards early (e.g., by using event count thresholds to warn of potential fracture risks).

[0059] Pest acoustic event data: Collected by pest acoustic pickups, this data counts events in specific frequency bands (such as insect activity sound waves). It is specifically used to monitor pest activities (such as termite feeding) and triggers micro-mist intervention when the event rate exceeds the limit.

[0060] VOC / Gas Data: Collected by a VOC / gas sensor, this data detects the concentration of volatile organic compounds (VOCs) and serves as an indicator of fungal metabolism. This data, combined with baseline comparisons (e.g., a 15% increase in VOC concentration compared to the baseline), determines microbial activity and supports the triggering of the photo-antimicrobial unit.

[0061] Regarding the technical solution of this embodiment, the data acquisition module includes the following:

[0062] A moisture content probe (needle type) is used to measure the internal moisture content of the wood structure. The moisture content probe adopts the DT-120 high-sensitivity sensor manufactured by Huashengchang. This embodiment does not make specific limitations and can be selected according to actual needs.

[0063] A temperature and humidity sensor is used to measure the ambient temperature and humidity on the surface of the wooden structure. The temperature and humidity sensor is a Link-Max LM-420 model, which can be used for outdoor waterproof and dustproof applications. This embodiment does not impose specific limitations and can be selected according to actual needs.

[0064] A thermal imaging micro-module is used to capture abnormal thermal image distributions. A near-infrared micro-module can also be selected. The thermal imaging micro-module model is set to AMG8833 infrared thermal imager array sensor with a resolution of 8×8 pixels, a detection distance of 7 meters, and support for USB power supply and communication. This embodiment does not impose specific limitations and can be selected according to actual needs.

[0065] An acoustic emission sensor is used to monitor crack activity in wooden structures (for crack activity event counting). The acoustic emission sensor model is set as VS150-K3: peak frequency 150kHz, protection level IP68, suitable for various acoustic emission applications, and has waterproof and mechanical stability. This embodiment does not make specific limitations and can be selected according to actual needs.

[0066] An acoustic pickup is used to monitor pest activity (limited frequency band event counting). The acoustic pickup adopts the SCS-YS1 type woodworm acoustic detector. This embodiment does not make specific limitations and can be selected according to actual needs.

[0067] A VOC gas sensor is used to monitor volatile organic compounds that indicate fungal metabolism (for baseline and threshold determination of fungal metabolism). The VOC gas sensor used is a KQ-2801 type gas sensor. This embodiment does not impose specific limitations and can be selected according to actual needs.

[0068] Regarding the technical solution of this embodiment, the intervention execution module includes a micro-dehumidification unit for reducing local environmental humidity, a photo-antibacterial unit for inhibiting microorganisms, and a micro-mist chamber for insect repellency or antibacterial purposes.

[0069] The micro dehumidification unit includes a Peltier condenser, a moisture-wicking pad or desiccant chamber, and a micro-air duct.

[0070] The photo-antibacterial unit is set as an LED array with a wavelength of 405nm.

[0071] The micro-atomizing chamber includes a replaceable drug tank, an atomizing plate, an atomizing chamber, and an air pump. The drug tank and the air pump are both connected to the atomizing chamber. The atomizing plate is installed inside the atomizing chamber. The liquid medicine inside the drug tank is input into the atomizing chamber. The high-frequency vibration of the atomizing plate turns the liquid medicine into a mist. Then, the air pump is started to produce the mist liquid.

[0072] Regarding the technical solution of this embodiment, the intervention execution module also includes a column base moisture-proof ventilation base. The height of the column base moisture-proof ventilation base is set to 10-25mm. The column base moisture-proof ventilation base includes a hydrophobic ceramic ring, a circumferential ventilation groove, and a probe holder. The hydrophobic ceramic ring is set on the top of the column base moisture-proof ventilation base. The circumferential ventilation groove and the probe holder are opened on the outer surface of the column base moisture-proof ventilation base. The column base moisture-proof ventilation base is installed in reverse between the wooden structure column base and the ground, and can be linked with the micro-air duct to improve drying efficiency.

[0073] Regarding the technical solution of this embodiment, the rule engine of the edge controller makes a judgment based on the judgment logic of threshold + hysteresis + variability + duration, as follows:

[0074] Dehumidification (R1): If the moisture content is ≥ the threshold and the temperature is within the safe range and the duration is ≥ the set time, the micro dehumidification unit will be activated;

[0075] Microbial inhibition (R2): The photo-antimicrobial unit is activated when the VOC gas content is ≥ the baseline increment threshold and the relative humidity is ≥ the threshold.

[0076] Insect Repellent (R3): If the insect acoustic event rate is greater than or equal to the threshold, the micro-mist chamber will be activated.

[0077] In accordance with the technical solution of this embodiment, the protection system also includes a power supply and communication unit for providing power and data transmission support to the system, and a human-machine interface (160) for system configuration, status monitoring and log query.

[0078] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0079] like Figure 1 The data acquisition module is arranged around the base of the target wooden component column. The intervention execution module communicates with the edge controller. After the system is powered on, it completes self-test and calibration, and acquires moisture content, temperature and humidity, and event count at a 2-minute sampling cycle. A VOC / acoustic / temperature and humidity baseline is established within 72 hours of initial installation. The rule engine determines the trigger based on the configured R1-R3 rules (including threshold, hysteresis, duration, cooling period, and maximum number of retry), and the intervention execution module drives the micro-dehumidification unit, photo-antibacterial unit, and micro-atomization chamber to execute. The system is forced to stop in case of emergency stop, over-temperature, leakage, dosage exceeding limit, or interlock conflict. The entire process log of trigger-execution-retest is recorded and uploaded or exported as a report.

[0080] like Figure 2The column base moisture-proof ventilation base includes a hydrophobic ceramic ring, a circumferential ventilation groove, and a probe holder. The column base moisture-proof ventilation base is installed in reverse between the wooden column base and the ground, forming a capillary water-blocking layer and a passive ventilation cavity, which can be linked with the micro-air duct to improve drying efficiency. The probe holder is used to place a moisture content probe and a surface temperature and humidity sensor. The column base moisture-proof ventilation base is 10-25mm high, reversibly disassembled, and can be linked with the micro-dehumidification unit: when the dehumidification operation is triggered, the micro-air duct assists the flow along the annular cavity to improve local drying efficiency.

[0081] In summary, this invention achieves a controllable steady-state of the on-site microenvironment at the component level by arranging multimodal sensors such as moisture content, temperature and humidity, thermal imaging, acoustic events, and VOCs on the surface and near the surface of the component, combined with a threshold + hysteresis + variability + timing rule engine and execution units such as local dehumidification, photo-antibacterial, and micro-mist antibacterial / insect repellent. This shortens the response time, reduces the risk of fungal decay and insect infestation, and forms a full-process traceability that can be integrated with HBIM / ledger.

[0090] Insect repellency: If the insect infestation acoustic event rate is greater than or equal to the threshold, the micro-mist chamber will be activated.
