Description

Technical Field

[0001] This application relates to the technical field of risk prevention and control, and particularly to a linkage management platform for the safety risk prevention and control of building envelopes. Background Art

[0002] With the acceleration of the urbanization process, a large number of high-rise buildings have emerged continuously, and the safety issues of building envelopes have received increasing attention. These structures include parts such as building exterior walls, and their safety is related to the safety of the people inside the building and the surrounding environment.

[0003] In the existing building safety management, usually each relevant party works independently. Insurance companies will conduct a general risk assessment on specific insured areas, which mainly determines the premium and the general scope of insurance based on information such as the claim data and building types in the past in this area; engineering parties will record the engineering information of the building envelope during the building construction process, such as materials, construction techniques, etc., and conduct a detection and record data once after the construction is completed; government regulatory departments will, according to relevant building safety regulations, conduct macro supervision and spot checks on building safety management, and order rectification for the problems found.

[0004] However, in this management mode, the detection units, insurance institutions and government regulatory departments work independently, lacking effective information sharing and coordination mechanisms, resulting in low efficiency of risk prevention and control, and it is difficult to discover and handle potential safety hazards in a timely manner. Summary of the Invention

[0005] This application provides a linkage management platform for the safety risk prevention and control of building envelopes, which is used to monitor the safety status of building exterior walls in real time through data sharing and linkage control among multiple departments, evaluate the situations with safety risks and formulate countermeasures to actively prevent the occurrence of safety accidents on building exterior walls.

[0006] In a first aspect, the present application provides a linkage management platform for preventing and controlling safety risks of building envelopes, including: an insurance information collection module for determining the insured area data of a preset insured area; an engineering detection module including an engineering information collection unit and an initial engineering inspection unit, where the engineering information collection unit is used to collect the engineering information of the building envelope, and the initial engineering inspection unit is used to obtain the initial inspection data after the first inspection of the building envelope; a government supervision module for determining the safety management data of the building envelope; a linkage controller communicatively connected to the insurance information collection module, the engineering detection module, and the government supervision module respectively, and used to perform a safety risk assessment on the building exterior wall according to the engineering information and the initial inspection data by using a preset risk rating mechanism. If the assessment result shows that the safety risk is in a preset safe stage, it is determined that there is no danger; if the assessment result shows that the safety risk is in a preset dangerous stage, it is determined that there is danger, and the assessment result is sent to the insurance information collection module and the government supervision module respectively, so that the insurance information collection module and the government supervision module determine an emergency plan according to the assessment result.

[0007] By adopting the above technical solution, after the safety risk assessment of the building exterior wall, if the assessment result shows a high safety risk, the insurance information collection module and the government supervision module can be triggered to take emergency measures to reduce the safety risk of the building exterior wall and ensure the safety of people's lives and property. The assessment result can be used as the basis for the insurance module to adjust the policy conditions and the government supervision department to conduct supervision, realizing the linkage prevention and control of the safety risk of the building exterior wall.

[0008] In combination with some embodiments of the first aspect, in some embodiments, the linkage controller includes a re-inspection module, which is used to receive the engineering detection information sent by the engineering detection module after determining that the emergency plan has been implemented, and perform a safety risk assessment on the building exterior wall again according to the engineering detection information until the assessment result meets the preset level.

[0009] By adopting the above technical solution, the building exterior wall can be continuously detected after the implementation of the emergency plan to obtain the latest wall safety status, and the risk assessment result can be adjusted accordingly to form a closed-loop management until the wall safety risk is reduced to an acceptable level, thereby ensuring the effectiveness of the emergency plan.

[0010] In combination with some embodiments of the first aspect, in some embodiments, it further includes an intelligent monitoring module communicatively connected to the linkage controller. When receiving that the assessment result sent by the linkage controller is level A, it monitors according to the first predetermined plan. The level A is a level that meets the preset standard and does not affect the wall safety. The first predetermined plan includes monitoring by drones and scanning equipment every six months and monitoring the set walls every quarter.

[0011] By adopting the above technical solution, for Class A walls with relatively low risks, a monitoring plan with a lower frequency can be adopted. For example, a comprehensive drone and scanning device monitoring is only carried out once every six months, and key walls are monitored quarterly. This can reduce the monitoring cost and avoid waste of resources. At the same time, through appropriate monitoring, safety problems of Class A walls can be detected in a timely manner, and measures can be taken to nip problems in the bud to ensure that the walls are in a safe state for a long time.

[0012] Combined with some embodiments of the first aspect, in some embodiments, the intelligent monitoring module is further configured to, when receiving the evaluation result of Class B sent by the linkage controller, monitor according to a second predetermined plan. The Class B is a level that meets the secondary preset standard and does not affect the safety of the wall. The second predetermined plan includes monitoring through drones and scanning devices quarterly and monitoring the set walls monthly.

[0013] By adopting the above technical solution, for Class B walls with relatively low risks, a more frequent monitoring plan than that for Class A walls is adopted. For example, a comprehensive drone and scanning device monitoring is carried out quarterly, and key walls are monitored monthly. This can timely detect potential safety hazards of Class B walls, and adopt more proactive monitoring measures compared with Class A walls to prevent the further increase of safety risks of Class B walls. By appropriately increasing the monitoring frequency, risk prevention and control measures can be taken more timely, and the safety risks of Class B walls can be controlled within an acceptable range.

[0014] Combined with some embodiments of the first aspect, in some embodiments, the intelligent monitoring module is further configured to, when receiving the evaluation result of Class C or Class D sent by the linkage controller, monitor according to a third predetermined plan. The Class C is a level where some preset standards are not met and it affects the safety of the wall, and the Class D is a level that completely does not meet the preset standards and affects the safety of the wall. The third predetermined plan includes monitoring through drones and scanning devices weekly during the repair period.

[0015] By adopting the above technical solution, for Class C and Class D walls with relatively high risks, due to serious problems affecting the safety of the walls, frequent monitoring is required. For example, drones and scanning devices are used for monitoring weekly during the repair period to timely master the safety status of the walls, be able to react quickly after problems are found, and guide the construction party for repair. Through frequent monitoring, further potential safety hazards during the repair process can be avoided, the repair quality can be guaranteed, the safety risks of the walls can be controlled within an acceptable range, and serious safety accidents can be avoided.

[0016] Combined with some embodiments of the first aspect, in some embodiments, the intelligent monitoring module is further configured to, during the monitoring process, when it monitors that the data changes abnormally exceeding the preset threshold, automatically send the abnormal alarm information to the linkage controller and the government supervision module.

[0017] By adopting the above technical solution, threshold alarms can be set during the wall monitoring process. When the monitored data changes abnormally beyond the threshold, an automatic alarm is triggered to promptly detect wall safety problems and take measures to avoid accidents. The alarm information is simultaneously sent to the linkage controller and the government supervision module to achieve a rapid response to problems.

[0018] In combination with some embodiments of the first aspect, in some embodiments, both the insurance information collection module and the government supervision module respectively include an economic effectiveness determination unit, an insured area data management unit, a renovation progress determination unit, a plan implementation situation determination unit, and a result display unit. Among them, the economic effectiveness determination unit is used to determine the economic benefits between input and output, the insured area data management unit is used to collect relevant data of the building envelope structure in the set insured area, the renovation progress determination unit is used to monitor the rectification and renovation progress of the risk hazards of the building envelope structure, the plan implementation situation determination unit is used to monitor the implementation of the risk prevention and control and emergency response plans, and the result display unit is used to directly display the risk assessment results and monitoring result information.

[0019] By adopting the above technical solution, the implementation effect of the risk prevention and control plan can be monitored from multiple perspectives such as economic benefits and visually displayed through the result display module, which is convenient for the decision-making department to comprehensively understand the implementation effect of the plan and timely optimize and improve the risk prevention and control plan.

[0020] In combination with some embodiments of the first aspect, in some embodiments, the economic effectiveness determination unit is further used to determine an economic benefit comparative analysis report according to different insurance plans and changes in risk assessment results and send it to the result display unit for display.

[0021] By adopting the above technical solution, the risk prevention and control plan with the best economic benefits can be selected for implementation according to the economic benefit comparison results of different plans, and the optimal allocation of resources can be achieved on the premise of ensuring safety.

[0022] In combination with some embodiments of the first aspect, in some embodiments, a data security determination module is further included, which is used to encrypt the data exchange between modules.

[0023] By adopting the above technical solution, the data exchange process of the platform can be encrypted, improving the security of data transmission and avoiding information leakage.

[0024] In combination with some embodiments of the first aspect, in some embodiments, the data security determination module includes a data backup unit, which is used to regularly back up and store the data of each module.

[0025] By adopting the above technical solution, the data of each module can be regularly backed up, improving data security, avoiding data loss caused by reasons such as hardware failures, and ensuring the reliable operation of the system.

[0026] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: 1. Due to the technical means of triggering the linkage between the insurance and government supervision modules according to the results of the safety risk assessment of the building exterior wall, the technical problem of the lack of information sharing and linkage between the existing building exterior wall safety management departments is effectively solved, and the technical effect of taking emergency measures actively according to the wall safety risk status is achieved.

[0027] 2. Due to the technical means of implementing a hierarchical monitoring plan according to the results of the wall safety risk assessment, the technical problem of the relatively single monitoring frequency for various types of walls in the prior art is effectively solved, the optimal allocation of resources is achieved, and the technical effect of implementing centralized monitoring for key walls is achieved.

[0028] 3. Due to the technical means of encrypting the platform data exchange process, the technical problem of poor data transmission security in the prior art is effectively solved, and the technical effect of protecting data security is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] The embodiments of the present application provide an intelligent video monitoring system for construction projects, as Figure 1 shown Figure 1 is a module connection diagram of the embodiments of the present application, including: An insurance information collection module 1, configured to determine the insured area data of a preset insured area; An engineering detection module 2, including an engineering information collection unit and an initial engineering inspection unit. The engineering information collection unit is configured to collect the engineering information of the building envelope structure, and the initial engineering inspection unit is configured to obtain the initial inspection data after the first inspection of the building envelope structure; A government supervision module 3, configured to determine the safety management data of the building envelope structure; A linkage controller 4, which is communicatively connected to the insurance information collection module 1, the engineering detection module 2, and the government supervision module 3 respectively, and is configured to perform a safety risk assessment on the building exterior wall by using a preset risk rating mechanism according to the engineering information and the initial inspection data. If the assessment result shows that the safety risk is in a preset safe stage, it is determined that there is no danger; If the assessment result shows that the safety risk is in a preset dangerous stage, it is determined that there is danger, and the assessment result is sent to the insurance information collection module 1 and the government supervision module 3 respectively, so that the insurance information collection module 1 and the government supervision module 3 determine an emergency plan according to the assessment result.

[0035] Specifically, the insurance information collection module 1 plays a crucial role in the entire building safety guarantee system. Its main function is to determine the insured area data of the preset insured area. First, in terms of data sources, it establishes interfaces with the core business systems of major insurance companies. These interfaces allow the module to obtain details of insurance policies related to buildings within the insured area. For example, basic information such as insurance policy numbers, applicant information, insurance start and end dates are extracted from insurance contract information. At the same time, for different types of insurance, details are recorded, such as the building types involved in building structure insurance, the scope of insurance liability, and the corresponding claim settlement terms and conditions. To more accurately determine the insured area data, this module also cooperates with databases and platforms related to geographic information. Through geocoding technology, the insured area is precisely located and divided on the map. This involves data docking with the government's public geographic information service platform or professional geographic surveying and mapping agencies to obtain topographic and geomorphic information and surrounding environment information of the area. These geographical factors are crucial for assessing the potential risks faced by buildings. For example, being close to a river may increase the flood risk, and being close to a transportation artery may increase the collision risk, etc. In addition, the insurance information collection module 1 also collects historical insurance claim data for this area. By analyzing this data, the types and frequencies of risks that buildings in this area have encountered in the past can be understood. For example, if there are frequent claims for building exterior wall seepage caused by heavy rain in a certain area, then when assessing the risks of the building's exterior envelope structure in this area, waterproofing-related factors need to be considered key. At the same time, these historical data also help to adjust insurance rates and optimize insurance products to better adapt to the risk characteristics of specific insured areas.

[0036] The project information collection unit in the engineering detection module 2 is used to comprehensively collect the engineering information of the building's exterior envelope structure. On the one hand, it closely cooperates with the digital design platform of the building design unit. Through Building Information Modeling (BIM) technology, the whole process information of the building's exterior envelope structure from design concept to detailed design is obtained. This includes the thickness of the wall, mechanical property parameters of materials (such as compressive strength, elastic modulus, etc.), thermal conductivity of thermal insulation materials, airtightness performance grade of doors and windows, etc. It also includes the name of the project, the year of completion, the construction unit, the design unit, the construction unit, the supervision unit, and the content of the construction method of the exterior wall project, specifically including drawings, construction techniques, etc. The data in the BIM model provides a highly accurate and detailed basis for project information collection. On the other hand, it docks with the information system of building material suppliers. Information such as batches of materials used during construction and quality inspection reports is understood. For example, for exterior wall coatings, the test results of performance indicators such as weather resistance, water resistance, and corrosion resistance can be obtained. At the same time, it is combined with the project management software during the building construction process to collect key data during construction, such as the implementation of construction techniques.

[0037] The project initial inspection unit is used to obtain relevant data after the first inspection of the building's exterior enclosure structure. In terms of structural safety inspection, non-destructive testing techniques such as ground-penetrating radar can be used by staff. Ground-penetrating radar can detect structural defects such as cavities and looseness inside the exterior wall. Its principle is to emit high-frequency electromagnetic waves and judge the internal structure of the wall based on the reflection characteristics of electromagnetic waves in different media. For the bearing capacity inspection of the wall, static load tests or micro-damage inspection methods will be adopted. The static load test applies a certain load on the wall surface and measures the deformation of the wall to evaluate its bearing capacity; micro-damage inspection is to drill a small number of samples on the wall and infer the overall performance of the wall by analyzing the mechanical properties of the samples in the laboratory, but this method causes minimal damage to the wall. In terms of waterproof performance inspection, spray tests and humidity detection will be carried out. The spray test simulates the scouring of rain on the building's exterior wall to observe whether there is any leakage phenomenon; humidity detection uses humidity sensors to detect the humidity change inside the exterior wall to judge whether there is water penetration. For the thermal insulation performance, the heat flow meter method is a commonly used means. By installing heat flow meters on the inner and outer surfaces of the wall, measuring the heat flow rate, and combining with the temperature difference of the wall, the thermal conductivity of the wall is calculated to evaluate the thermal insulation effect. In addition, the inspection of the appearance quality is also an important part of the project initial inspection. Professional personnel will check whether there are cracks, peeling, fading and other phenomena on the exterior wall surface and record information such as their positions, lengths, and widths. These appearance defects may imply deeper quality problems.

[0038] The government supervision module 3 is connected to the construction project quality supervision and management system of the construction administrative department to obtain supervision data throughout the entire life cycle of a building from planning, design, construction to completion acceptance. During the planning stage, it understands the positioning and requirements of the building's exterior envelope structure in urban planning, such as whether it conforms to the urban style planning and whether the spacing from surrounding buildings meets requirements such as fire prevention and lighting. During the design review stage, it obtains the review opinions on the design scheme of the building's exterior envelope structure, including aspects such as the safety of the structural design and the rationality of the energy-saving design. During the construction process, it interacts with the quality supervision and management system in real time to obtain quality spot-check data, violation records, etc. during the construction process. For example, if the construction unit cuts corners or fails to construct according to the design requirements during the construction of the building exterior wall, this information will be recorded. The data in the completion acceptance stage is even more crucial, including the acceptance reports of various performance indicators of the building's exterior envelope structure (such as fire resistance performance, seismic performance, etc.), records of rectification situations, etc. At the same time, this module is also connected to the fire safety management system of the fire department to obtain fire-related data on the building's exterior envelope structure, such as the combustion performance grade of the exterior wall insulation material, the setting of fire rescue windows, and whether the setting of the fire fighting elevation meets the specifications. This information is crucial for preventing and dealing with building fires. In addition, it collaborates with the database of the work safety supervision and management department to obtain work safety data during the use of the building. For example, whether there are safety hazards in the building's exterior envelope structure caused by improper use or aging, and whether there are potential risks caused by changes in the surrounding environment (such as the impact of new projects on the foundation of the original building).

[0039] The linkage controller 4 integrates the insurance information collection module 1, the engineering detection module 2, and the government supervision module 3 through communication connections to achieve the safety risk assessment of the building exterior wall and the coordination of emergency plans. During the safety risk assessment process, the linkage controller 4 operates according to a preset risk rating mechanism. This mechanism is a complex model that comprehensively considers various factors. It first standardizes the engineering information and initial detection data collected by the engineering detection module 2. For example, it converts various physical quantities (such as the strength value and thermal conductivity of the wall) obtained by different detection devices into unified dimensionless values for subsequent calculations. For each risk factor of the building envelope structure, the linkage controller 4 assigns different weights, and the determination of the weights is based on a large amount of industry research, historical accident data analysis, and expert experience. For example, for high-rise buildings, the weight of the structural stability of the exterior wall may be relatively high because structural damage may lead to serious consequences; while for some buildings in old communities, the weights of the fire resistance performance and thermal insulation performance of the exterior wall may be appropriately increased because these buildings may have more problems in terms of fire protection and energy efficiency. Then, through weighted calculation and comprehensive evaluation, the safety risks of the building exterior wall are divided into different stages. When the assessment result shows that the safety risk is in the preset safe stage, where the preset safe stage includes level A and level B, the linkage controller 4 determines that the building is currently not in danger. At this time, it will send instructions to each module to maintain the monitoring state and regularly require the engineering detection module 2 to update the detection data to ensure the continuous stability of the building safety condition.

[0040] If the assessment result indicates that the safety risk is in the preset dangerous stage, where the preset dangerous stage can include level C and level D, the linkage controller 4 quickly sends this assessment result to the insurance information collection module 1 and the government supervision module 3 respectively. For the insurance information collection module 1, after receiving the dangerous assessment result, it will initiate an emergency plan based on the insured area data and insurance contract terms.

[0041] Through this mechanism of multi-module collaboration, data-driven, and risk assessment, the entire system can effectively ensure the safety of the building envelope structure, promptly respond to possible dangerous situations, and achieve the whole-process management from prevention, detection to emergency handling.

[0042] For easy understanding, the following further describes the modules of the system provided in this embodiment in combination with the above scenario. Please refer to Figure 2 , Figure 2 which is another module connection diagram of the embodiment of this application.

[0043] In Figure 2Among them, the linkage controller 4 in the safety risk prevention and control linkage management platform for building envelopes includes a re-inspection module 5. The re-inspection module 5 is used to receive the engineering inspection information sent by the engineering inspection module 2 after determining that the emergency plan has been implemented, and re-evaluate the safety risks of the building exterior wall according to the engineering inspection information until the evaluation result meets the preset level. Specifically, the main function of the re-inspection module 5 is to continuously evaluate and monitor the safety status of the building exterior wall after the implementation of the emergency plan to ensure that the building safety risks are reduced to the preset level. It is a dynamic evaluation system that iteratively analyzes the safety status of the building exterior wall by continuously receiving information from the engineering inspection module 2, thus forming a closed loop for building safety management. This process effectively avoids the situation where building safety problems still exist or deteriorate due to improper implementation of the emergency plan or the emergence of new risk factors. A stable and efficient communication link is established between the re-inspection module 5 and the engineering inspection module 2. After the emergency plan starts to be implemented, the engineering inspection module 2 will send engineering inspection information to the re-inspection module 5 at specific time intervals or inspection process trigger points. These information cover data in multiple aspects of the building envelope, including but not limited to wall structure integrity data (such as changes in crack width and depth, structural deformation, etc.), material performance data (such as changes in the thermal conductivity of thermal insulation materials, waterproof performance changes of waterproof materials, etc.), and installation and connection status data of key parts (such as connection stability between doors and windows and the wall, etc.).

[0044] When receiving information, the re-inspection module 5 has a powerful data compatibility and accuracy verification mechanism. It can process data formats generated by different detection devices and detection methods. Whether it is the digital real-time data transmitted by the sensor network or the formatted data entered after manual detection records, it can be accurately received. At the same time, for the accuracy verification of data, it will make judgments based on the preset range and logic. For example, whether the detection data is within a reasonable physical range, and whether the different relevant data conforms to physical laws and building structure principles. If abnormal data is found, it will be marked in time and the engineering detection module 2 will be required to re-verify. The re-inspection module 5 uses a complex and accurate risk assessment model to conduct a safety risk assessment of the building exterior wall again. This model is constructed based on multi-disciplinary theories such as building structural mechanics, materials science, thermodynamics, and fluid mechanics. It considers the mechanical responses, heat and moisture transfer characteristics, durability changes, etc. of the building envelope under normal use and various external factors (such as wind and rain, temperature changes, earthquakes, etc.). The model contains a large number of parameters and equations, and these parameters are determined through long-term experimental research, statistical analysis of on-site monitoring data, and industry experience formulas. For example, according to the experimental data of the aging speed of different wall materials in different humidity environments, the influence weight of humidity on the safety risk of the wall structure is determined; according to the statistical analysis of the failure modes of the building exterior wall under different earthquake intensities, the proportion of the structural seismic performance in the risk assessment is evaluated.

[0045] During the assessment process, the re-inspection module 5 will dynamically adjust the parameters in the risk assessment model according to the latest engineering detection information. This is because during the use of the building, its structural and material properties may change over time and with the external environment, and the implementation effect of the emergency plan will also affect these parameters. At the same time, the re-inspection module 5 will feedback information to the relevant modules according to each assessment result. If the assessment result shows that the risk is still high and does not meet the preset Class B, it will put forward more detailed detection requirements to the engineering detection module 2. The re-inspection module 5 will continuously repeat the above information reception, processing, and risk assessment processes until the safety risk assessment result of the building exterior wall meets the preset level.

[0046] In some embodiments, the safety risk prevention and control linkage management platform for the building envelope further includes an intelligent monitoring module 6, which is communicatively connected to the linkage controller 4. When receiving the evaluation result of Class A sent by the linkage controller 4, it will conduct monitoring according to the first predetermined plan. The Class A is a level that meets the preset standard and does not affect the safety of the wall. The first predetermined plan includes conducting monitoring every six months through drones and scanning devices, and conducting monitoring on the set walls every quarter.

[0047] Specifically, the core function of the intelligent monitoring module 6 is to carry out targeted monitoring work according to the safety assessment level of the building's exterior envelope structure. If the set level is A, more specifically, the monitoring by drones and scanning equipment carried out every six months is an efficient and comprehensive monitoring method. The drones are equipped with a variety of high-precision sensors and scanning equipment, such as high-definition cameras, infrared thermal imagers, lidar, etc. During the monitoring process, the drones fly around the building along the preset flight path to ensure full coverage of the building's exterior envelope structure. The high-definition camera can take pictures of the exterior of the building wall, and through image recognition technology, analyze whether there are new cracks, peeling, color changes, etc. on the exterior wall surface. The infrared thermal imager can detect the temperature distribution of the exterior wall and identify potential problems such as insulation layer defects and leakage points. Because when there is heat leakage inside the building or water penetration in the exterior wall, temperature abnormal areas will be shown on the infrared image. The lidar can accurately measure the three-dimensional geometry of the exterior wall and compare it with the previous measurement data to judge whether the wall has deformation or displacement. These data will be transmitted back to the intelligent monitoring module 6 in real time for analysis and storage. For a very small number of set walls, the monitoring is carried out once a quarter, which is a more targeted local inspection. Key walls in some key parts of the building or walls judged to be relatively weak according to historical data are focused on. This kind of monitoring may adopt a method combining manual inspection and instrument detection. In terms of manual inspection, professional inspectors will closely observe the surface of the wall and use tools to check the sealing and connection conditions of parts such as doors, windows, internal and external corners, etc. At the same time, the staff can also use portable detection instruments, such as hardness testers, ultrasonic flaw detectors, etc., to detect the material properties and internal structure of the wall. The hardness tester can detect the hardness change of the wall material to judge whether there is material aging or damage; the ultrasonic flaw detector can detect whether there are hidden cracks or defects inside the wall, and determine the abnormal position and size by analyzing the reflection and propagation time of ultrasonic waves. These detailed inspection results will be recorded and compared with the previous monitoring data for analysis to timely discover the development trend of potential problems.

[0048] This dynamic adjustment mechanism makes the intelligent monitoring work more scientific and reasonable, and better adapts to the safety monitoring needs of the building in different periods and different environments.

[0049] In some embodiments, the intelligent monitoring module 6 in the safety risk prevention and control linkage management platform for building envelopes is further configured to, upon receiving the evaluation result of grade B sent by the linkage controller 4, perform monitoring according to a second predetermined plan. The grade B is a level that meets the secondary preset standard and does not affect the safety of the wall. The second predetermined plan includes monitoring quarterly through drones and scanning devices, and monthly monitoring of the set walls. Specifically, the communication unit in the intelligent monitoring module 6 receives the wall safety evaluation result from the linkage controller 4, extracts the wall information with the result level of grade B, and the linkage controller 4 calls the corresponding second predetermined monitoring plan of the wall in the monitoring plan module according to the extracted grade B wall information. The plan includes a comprehensive quarterly monitoring by drones and scanning devices, and monthly monitoring of a very small number of set walls. The monitoring execution unit arranges for drones and scanning devices to monitor the grade B walls according to the predetermined plan. The drones can detect the surface conditions of the walls through image shooting and thermal imaging. Scanning devices such as seismic wave detectors can scan the internal structure of the walls. The combination of the two can comprehensively monitor the safety status of the grade B walls.

[0050] Through the hierarchical monitoring plan formulated by the intelligent monitoring module 6 for grade B walls, optimization can be achieved in terms of frequency and resource investment, which can not only ensure timely detection of problems but also avoid over-monitoring of walls with low safety risks, effectively improving the pertinence and intelligent level of the monitoring work.

[0051] In some embodiments, the intelligent monitoring module 6 in the linkage management platform for preventing and controlling the safety risks of building envelopes is further configured to, upon receiving the evaluation result of grade C or D sent by the linkage controller 4, monitor according to a third predetermined plan. Grade C is a level where some parts do not meet the preset standard and affect the safety of the wall, and grade D is a level where it completely does not meet the preset standard and affects the safety of the wall. The third predetermined plan includes monitoring via drones and scanning devices every week during the repair period. Specifically, the intelligent monitoring module 6 receives the wall safety evaluation result from the linkage controller 4 and extracts the wall information with the result level of grade C or D. If the linkage controller 4 determines that there are serious safety hazards in these walls, according to the predetermined plan, weekly monitoring needs to be initiated during the occurrence of danger points and the repair period. The monitoring execution unit arranges for drones and scanning devices to monitor grade C and D walls every week. Due to structural problems, the weekly monitoring frequency needs to be increased to detect problems in a timely manner. The linkage controller 4 uses drone images and scanning data, and adopts image recognition and signal processing algorithms to judge the problem areas of the wall and the phased repair effect. If the monitoring data is abnormal, corresponding measures are taken for verification testing. If danger is confirmed, detailed testing should be carried out. After completion, the development of defects is reported in a timely manner. The monitoring results are also synchronously sent to the government supervision department to strengthen the supervision of grade C and D walls. Through intensive monitoring of grade C and D walls, problems can be discovered in a timely manner to ensure safety during the repair process. At the same time, the feedback of monitoring results can optimize the repair plan and improve the repair effect.

[0052] In some embodiments, the intelligent monitoring module 6 in the linkage management platform for preventing and controlling the safety risks of building envelopes is further configured to automatically send abnormal alarm information to the linkage controller 4 and the government supervision module 3 when abnormal changes in the monitored data exceed a preset threshold during the monitoring process. Specifically, in the set parameters of the intelligent monitoring module 6, the normal threshold ranges of various types of monitored data are pre-configured, such as the preset upper and lower limits of image pixel changes, heat energy signals, vibration parameters, etc. The monitoring execution unit uses drones and scanners to collect data on the wall to obtain various first-hand monitored data. The linkage controller 4 will use professional algorithms to analyze and judge the monitored data, extract the values of the monitored quantities, and compare them with the preset normal threshold ranges. If the monitored data is abnormal and exceeds the upper or lower limit, it is determined as an abnormal change. The intelligent monitoring module 6 records information such as the abnormal monitored quantity, monitoring time, and wall location to form an abnormal report. At the same time, the abnormal report will be immediately sent to the linkage controller 4 and the government supervision module 3. After receiving the alarm, the linkage controller 4 will notify the corresponding monitoring or management personnel to go to the corresponding wall location for inspection to eliminate faults or take risk prevention and control measures. When the government supervision module 3 receives an abnormal alarm, it will also arrange relevant departments to make emergency preparations and send people to the scene if necessary to prevent the accident from expanding. Regardless of the result, these abnormal alarm information will be stored in the database of the monitoring module to leave a complete processing record, providing a basis for analyzing and judging the cause of the abnormality in the later stage. By setting up an automatic alarm mechanism, once the monitored data is abnormal, relevant responsible parties can quickly learn and respond, controlling the wall safety hazards within a controllable range and preventing serious accidents to the greatest extent.

[0053] In some embodiments, the insurance information collection module 1 and the government supervision module 3 in the linkage management platform for preventing and controlling the safety risks of building envelopes each include an economic effectiveness determination unit 7, an insured area data management unit 8, a renovation progress determination unit 9, a plan implementation situation determination unit 10, and a result display unit 11. Among them, the economic effectiveness determination unit 7 is used to determine the economic benefits between input and output, the insured area data management unit 8 is used to collect relevant data on the building envelopes in the set insured area, the renovation progress determination unit 9 is used to monitor the rectification and renovation progress of the risk hazards of the building envelopes, the plan implementation situation determination unit 10 is used to monitor the implementation of the risk prevention and control and emergency response plans, and the result display unit 11 is used to directly display the risk assessment results and monitoring result information.

[0054] Specifically, the economic effectiveness determination unit 7, which is possessed by both the insurance information collection module 1 and the government supervision module 3, will collect data on the input costs of safety protection, compare the losses avoided by prevention and control actions, and calculate economic benefit indicators such as return on investment and investment value ratio through model algorithm analysis. The insured area data management unit 8 forms a database of the exterior wall safety of each building in the area by collecting data such as exterior wall project information, monitoring results, and risk ratings, providing a basis for insurance pricing and government supervision. The renovation progress determination unit 9 will connect to the construction unit system to obtain information such as the exterior wall renovation schedule and step plan, so as to monitor whether the rectification is carried out according to the progress and avoid greater safety hazards caused by delays. The plan implementation situation determination unit 10 judges whether the emergency plan is effective after implementation through means such as on-site inspections and data comparison. If the risk indicators rebound, the plan needs to be re-evaluated and optimized. The result display unit 11 uses a visual system interface to display information such as risk assessment results, renovation progress, and economic benefit analysis at the same time, presenting the panoramic view of exterior wall safety management intuitively. Each unit is interconnected through an internal network to form a closed-loop feedback. If subsequent monitoring results need to be adjusted, the corresponding business unit can be notified in time for optimization.

[0055] In some embodiments, the economic effectiveness determination unit 7 in the safety risk prevention and control linkage management platform for building enclosures is further configured to determine an economic benefit comparison analysis report according to different insurance plans and changes in risk assessment results and send it to the result display unit 11 for display. Specifically, a variety of insurance models are preset in the insurance plan library, including basic plans, regular plans, premium plans, etc., with differences in coverage, premium rates, claim settlement methods, etc. The risk assessment results will change in real time due to the wall safety conditions and the prevention and control measures taken, and there will be differences in the assessment results at different times. The economic effectiveness determination unit 7 can call various plans in the insurance plan library and combine them with the corresponding historical period risk assessment results. By establishing a mathematical model and considering various factors such as premium settings, claim settlement methods, and risk levels, dynamically calculate the cost-benefit comparison of each plan at different risk levels. The economic benefit comparison module will comprehensively compare the profit and loss situations of different insurance plans, determine the optimal plan. If multiple plans are close, candidate recommendations can be listed, generating an economic benefit comparison analysis report, presenting the advantages and disadvantages of each plan in an intuitive chart form, and the system will automatically send it to the result display unit 11. The display unit displays it through a visual interface, facilitating the insurance and supervision departments to comprehensively understand the economic benefits of different models and adjust the insurance strategy or supervision standards accordingly. If the risk assessment results change significantly, the analysis process can be restarted to dynamically update the economic benefit comparison results.

[0056] In some embodiments, the linkage management platform for preventing and controlling the safety risks of building envelopes further includes a data security determination module 12, which is used to encrypt the data exchange between modules. Specifically, the specific technical implementation of data encryption transmission of the data security determination module 12 in the safety risk management platform of building envelopes is as follows: An encrypted transmission channel is set up between the internal networks of the platform, and the interfaces between each functional module pass through the encrypted channel. The encryption module selects a national commercial encryption algorithm, and through mechanisms such as secure public keys, private keys, and digital signatures, it ensures the confidentiality, integrity, and non-repudiation of the data transmission process. An encryption and decryption module is deployed on each server, which is responsible for encrypting, decrypting, and signature verification operations on the sent and received data. The key key is stored in a secure hardware encryption module. The encryption module allows the configuration of policies with different encryption strengths, and different encryption levels are set for data with different security levels, such as general monitoring data, wall safety assessment results, emergency plans, etc. Before all data is transmitted between modules, the sending encryption module encrypts the data content, and the transmission content becomes in a scrambled form and cannot be parsed by a man-in-the-middle. The decryption module on the receiving server uses the key to decrypt the transmitted data, restores the original content, and then inputs it into the application module for processing. Through the digital signature mechanism, the receiving party can verify the authenticity of the data source and the integrity of the content, preventing tampering. Information such as encryption certificates and logs will be recorded during the transmission process of key data, the data is traceable, effectively maintaining the auditability of the system. Security auditors can regularly check the logs to ensure the security of the encrypted transmission environment and optimize any potential problems in a timely manner.

[0057] In some embodiments, the data security determination module 12 in the linkage management platform for preventing and controlling the safety risks of building envelopes includes a data backup unit 13, which is used to regularly back up and store the data of each module. Specifically, a data backup interface is set up in each functional module for outputting the data to be backed up. The data backup unit 13 will be started regularly or triggered by an event to send backup instructions to each module. After receiving the instruction, the module outputs core business data, such as risk assessment data, monitoring results, audit logs, etc., through the backup interface. The backup unit will perform data integrity verification, such as verification based on check blocks, to ensure data integrity. The output data is processed using compression and encryption technologies to reduce the storage space and ensure security. The processed data will be stored on a dedicated backup storage server, and a redundancy mechanism is adopted so that the data can be restored even if the storage device is damaged. The backup adopts version management, and multiple generations of backups can be retained in chronological order to facilitate the verification of historical data. The backup type (full or incremental) and the number of generations to be retained are defined through backup policies to automatically control the storage space. The backup unit will generate a backup report, recording information such as backup time, data volume, and whether it is successful. In case of necessity, the module business information can be directly restored from the backup data to ensure the reliable operation of the system.
