Abstract
Description
Technical Field
[0001] This invention relates to the field of building monitoring technology, and in particular to a building structural deformation monitoring system. Background Technology
[0002] A house is a fundamental place for people to live and work, and its structural safety is of paramount importance. Cracks appearing in walls and floors are a common problem encountered by homeowners after daily living or renovations. These cracks not only affect aesthetics but may also indicate potential structural safety hazards, causing widespread anxiety among residents. The causes of wall cracks are complex and diverse. On the one hand, some cracks are caused by non-structural factors, such as the natural shrinkage of building materials (e.g., mortar, concrete), thermal expansion and contraction due to temperature changes, or improper construction. These cracks are usually shallow and fine, and have little impact on the overall structural safety of the house. On the other hand, some cracks are caused by structural factors, such as uneven foundation settlement, insufficient load-bearing capacity of load-bearing components, aging of building materials, and the impact of surrounding construction work. These structural cracks, especially those that continue to develop, can seriously threaten the structural safety of the house.
[0003] However, ordinary homeowners lack the professional knowledge and testing tools to accurately determine the nature and cause of cracks. When wall cracks are discovered, homeowners cannot distinguish between normal material shrinkage cracks and dangerous structural cracks, which can easily lead to two extremes: either excessive panic, wasting unnecessary energy and money on harmless cracks; or complacency, ignoring early warning signs that may indicate serious structural problems and missing the best time to deal with them.
[0004] Currently, homeowners face limited and inefficient avenues for seeking professional assistance. Finding authoritative testing agencies is a cumbersome process, and the quality of services in the market varies greatly. From the time a homeowner discovers a problem to when professionals arrive for on-site inspection, information barriers often exist, lacking a convenient and standardized service entry point. Even when professionals are contacted, the entire inspection and analysis process is typically a "black box" for the homeowner. Homeowners are unaware of the specific content, scientific basis, and progress of the inspection work, which can easily lead to doubts and even disputes due to a lack of transparency.
[0005] Therefore, a building structure deformation monitoring system that is easy to provide feedback and can effectively assess deformation risk is needed. Summary of the Invention
[0006] This invention provides a building structure deformation monitoring system that simplifies the homeowner feedback process and effectively assesses deformation risks.
[0007] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0008] A building structure deformation monitoring system includes a user terminal, a server terminal, and a worker terminal;
[0009] The wall crack data is used by the user to upload, and the wall crack data includes crack images and the location of the cracks.
[0010] The server-side includes an analysis module and a work order dispatch module; the analysis module is used to identify the severity of cracks based on their location and crack images; the work order dispatch module is used to generate monitoring work orders based on the severity of cracks and send them to the worker terminals.
[0011] The client is used to upload on-site survey information;
[0012] The analysis module is also used to generate settlement and deformation analysis reports based on on-site survey information.
[0013] Furthermore, the analysis module is used to filter out crack images of different floors in the same building from the wall crack data uploaded by each user, based on the location of the cracks; determine whether the number of floors is greater than a number threshold; if it is not greater than the number threshold, identify the width of the crack in the crack image, determine whether the width is greater than a first width threshold, and calculate the ratio of the crack length to the wall surface it is located on; if it is greater than the first width threshold and the ratio is greater than the ratio threshold, it is judged as high severity; otherwise, a manual verification request is generated.
[0014] If the number of floors exceeds the number threshold, identify whether the cracks in the crack image are larger than the second width threshold. If they are larger, the severity is judged to be high; if they are not larger than the second width threshold, generate a manual verification request.
[0015] Among them, the first width threshold is greater than the second width threshold;
[0016] The work order dispatch module is used to generate monitoring work orders based on the buildings with the highest severity levels.
[0017] Furthermore, the working terminal is also used to upload monitoring equipment installation information;
[0018] The analysis module is also used to acquire monitoring data from monitoring equipment, analyze settlement deformation based on the monitoring data, and improve the settlement deformation analysis report.
[0019] Furthermore, the monitoring equipment includes a BeiDou micro-displacement reference station;
[0020] The analysis module is also used to acquire the three-dimensional coordinate data of the Beidou micro-displacement reference station and calculate the settlement deformation over a preset monitoring time.
[0021] Furthermore, the server also includes an information acquisition module, which is used to receive wall crack data from the user terminal and to send image acquisition requests to the user terminal.
[0022] Furthermore, the working terminal is also used to upload the survey plan; the analysis module is also used to generate a survey progress bar and survey description information based on the survey plan, and send the survey progress bar and survey description information to the corresponding user terminal.
[0023] Furthermore, the analysis module is also used to update the survey progress bar based on the on-site survey information.
[0024] Furthermore, the work order dispatch module is also used to obtain the user's contact information from the user terminal and send the user's contact information to the work terminal.
[0025] This solution combines user-uploaded data, intelligent analysis, and professional manual surveying to achieve efficient and accurate assessment of structural deformation risks in buildings. Compared to traditional single-crack assessments, this solution uses the number of cracks appearing on multiple floors of the same building as a key indicator, enabling rapid identification of potential systemic structural problems and early warning. This not only avoids excessive panic among homeowners regarding harmless cracks but also allows professional resources to be concentrated on addressing high-risk hazards, significantly improving processing efficiency. Furthermore, by generating a visual progress bar and professional analysis reports, the entire survey process is made transparent, providing homeowners with reliable decision-making support and effectively reducing the risks and anxiety caused by information asymmetry. Attached Figure Description
[0026] Figure 1 This is a logic block diagram of an embodiment of a building structure deformation monitoring system. Detailed Implementation
[0027] The following detailed description illustrates the specific implementation method:
[0028] Example 1
[0029] like Figure 1 As shown in the figure, a building structure deformation monitoring system according to this embodiment includes a user terminal, a server terminal, and a work terminal. The user terminal and the work terminal are smartphones with corresponding application programs installed, and the server terminal is deployed in a cloud server.
[0030] The client application is used by users to upload data on wall cracks. This data includes crack images and the location of the cracks. The location of the crack is, for example, "[Community Name], Building XX, Floor XX, Apartment XX, Specific Wall / Ceiling Target."
[0031] The server-side includes an information collection module, an analysis module, and a work order dispatch module.
[0032] The information acquisition module is used to receive wall crack data from the user terminal and also to send image acquisition requests to the user terminal. For example, when taking crack images, it is necessary to take pictures of the entire wall (if the crack cannot be shown in the overall picture, it is necessary to manually draw lines and mark along the crack direction), the local condition of the crack, and at the same time use a ruler to measure the width of the widest part of the crack and take a picture.
[0033] The analysis module is used to identify the severity of cracks based on their location and images; the work order dispatch module is used to generate monitoring work orders based on the severity of cracks and send them to the work terminals.
[0034] Specifically, the analysis module is used to filter crack images from different floors of the same building based on the location of cracks in the wall crack data uploaded by each user; it determines whether the number of floors exceeds a number threshold. If it does not exceed the number threshold, it identifies the width of the crack in the crack image and determines whether the width exceeds a first width threshold, and calculates the proportion of the crack length to the wall surface. If it exceeds the first width threshold and the proportion exceeds the proportion threshold, it is judged as high severity; otherwise, a manual verification request is generated. In this embodiment, the width of the crack in the crack image is identified by reading the scale of the ruler in the image. When calculating the proportion of the crack length to the wall surface, the crack or the marked line is first identified, and then the components of the crack in the length and width directions of the wall surface are calculated. The proportion in the corresponding length and width directions of the wall surface is calculated respectively, and the direction with the highest proportion is taken as the overall direction.
[0035] If the number of floors exceeds the number threshold, the system identifies whether the cracks in the crack image are larger than the second width threshold. If they are larger, the severity is judged to be high. If they are not larger than the second width threshold, a manual verification request is generated. In this embodiment, the manual verification request is manually identified and processed by a designated person.
[0036] Wherein, the first width threshold is greater than the second width threshold. In this embodiment, the first width threshold is 1.1mm-2mm, for example 1.5mm; the second width threshold is 0.4mm-1mm, for example 0.5mm.
[0037] The work order dispatch module generates monitoring work orders based on the buildings with the highest severity levels. In this embodiment, the monitoring work order content includes: basic information, such as work order number, generation time, and processing time limit; task information, such as problem description, building address, specific location, and task type; and attachments and data, such as original images.
[0038] The work order dispatch module is also used to obtain users' contact information from the user terminal and send the user's contact information to the work terminal, so that staff can make an appointment with the user in advance and determine the time for on-site inspection.
[0039] The workstation is also used to upload survey plans; the analysis module is used to generate survey progress bars and survey description information based on the survey plans, and then send these information to the corresponding user terminals. The survey description information provides a basic overview of the manual survey work, helping users understand and cooperate with the survey work, effectively avoiding doubts and disputes arising from a lack of transparency.
[0040] In this embodiment, the survey progress bar nodes include: survey plan formulated and awaiting on-site inspection; on-site survey; data analysis and report writing; settlement and deformation analysis report completed, etc. The estimated completion time is displayed before each progress bar node is completed, and the actual completion time is displayed after completion. For example, if the on-site survey includes deformation and settlement observation, the survey description information would be: Engineers use precision equipment such as levels to set up observation points at key locations of the building (such as the foundation and load-bearing walls) and accurately measure their elevation. This is a scientific method to determine whether there is uneven settlement in the building (i.e., different parts of the building settle at different rates). Uneven settlement is a common underlying cause of wall cracking, and accurate data is crucial for assessing the structural safety of a building.
[0041] The client is used to upload on-site survey information. If necessary, the client can also be used to upload monitoring equipment installation information.
[0042] The on-site survey information in this plan includes:
[0043] Detailed crack survey includes staff systematically inspecting key components such as interior and exterior walls, floors, ceilings, beams, and columns to look for other cracks, taking photos of all typical cracks found, and drawing a crack distribution diagram on the floor plan.
[0044] Inquire and investigate, communicate with users or residents to understand when the cracks appeared, how quickly they developed, and whether there were any unusual noises. Understand the building's construction history, whether it has been renovated or altered.
[0045] For deformation and settlement monitoring, locate existing settlement monitoring points on the building. If none are found, establish temporary settlement monitoring points at the building foundation and load-bearing walls / columns according to specifications. Using a level and leveling rod, measure the elevation of each monitoring point with a stable benchmark as a reference, and record the readings. Calculate the uneven settlement by comparing the data with historical data (if available) or data from the current monitoring.
[0046] In this embodiment, the monitoring equipment uses a Beidou micro-displacement reference station. The staff also determines the duration of continuous monitoring based on the actual situation on site. If necessary, a Beidou micro-displacement reference station is installed at the selected location, and the installation location and other information of the Beidou micro-displacement reference station are recorded as installation information and uploaded.
[0047] The analysis module also updates the survey progress bar based on on-site survey information, allowing users to easily monitor the survey progress in real time.
[0048] When monitoring equipment installation information is not provided, the analysis module is also used to generate a settlement deformation analysis report based on on-site survey information. When monitoring equipment installation information is provided, the analysis module is also used to acquire monitoring data from the monitoring equipment, analyze settlement deformation based on the monitoring data, and improve the settlement deformation analysis report. The analysis module is also used to acquire the three-dimensional coordinate data of the Beidou micro-displacement reference station and calculate the settlement deformation over a preset monitoring time.
[0049] In this embodiment, the settlement deformation analysis report includes a project overview, survey basis, analysis and results (including a summary description of the distribution, shape, width, and length of cracks on site, and an analysis of their causes; displaying settlement data of each monitoring point in the form of tables and charts, including cumulative settlement and current settlement; drawing settlement curves, overall building settlement contour maps, lateral displacement maps, etc., to intuitively show the deformation trend of the building, etc.), conclusions and recommendations (for example, the current building settlement has stabilized and has not exceeded the standard limit, the structure is safe, or the current building has uneven settlement and the rate is fast, exceeding the standard limit, posing a safety hazard), etc.
[0050] This solution collects crack data uploaded by users through an information acquisition module and performs preliminary automated assessments based on the analysis module. Traditional crack assessments typically focus only on the width and length of individual cracks. This solution uses the number of cracks appearing on different floors within the same building as a key indicator. When residents on multiple floors report crack problems, there is a high probability that the entire building has a common, deep-seated structural problem. When cracks appear on multiple floors, the system quickly generates a monitoring work order, arranges for professional personnel to conduct on-site surveys, and may install monitoring equipment for long-term tracking. This allows structural hazards to be professionally and scientifically assessed and addressed before the problem escalates and causes serious consequences, thereby significantly reducing building safety risks and homeowners' economic losses.
[0051] Furthermore, by identifying the width and length proportions of cracks and combining this with data on cracks appearing on multiple floors within the same building, the system can quickly distinguish high-severity potential structural problems requiring priority attention, thus preventing homeowners from excessively panicking about harmless cracks. Moreover, automated analysis reduces the workload of initial manual assessments, allowing professionals to focus their limited efforts on buildings most likely to have structural safety hazards. For uncertain or less serious cases, the system generates manual verification requests, ensuring the rigor of the assessment while improving overall processing efficiency.
[0052] Through the survey plan and progress bar, users can track every step of the survey work in real time, effectively alleviating anxiety caused by information asymmetry. Furthermore, this solution can leverage on-site survey data collected by staff and combine it with advanced monitoring equipment for long-term, continuous settlement and deformation monitoring, providing more accurate and comprehensive data support. The resulting analysis report can provide owners with reliable decision-making support, helping them take appropriate follow-up measures.
