They are unable to actively supervise and deal with dangerous behaviors in different building renovations through different methods, resulting in poor active supervision and analysis of different aspects of building safety assessment risk situation awareness. Summary of the Invention

[0009] According to the coordinate sets corresponding to the target areas, the processing areas corresponding to the same coordinates in the house planning drawings are sequentially obtained, and the processing areas corresponding to the processing areas are obtained;

[0010] Compare and judge the treated area of the treated region with the corresponding target area according to the coordinate set;

[0011] If the treatment area of the treatment area is the same as the corresponding target area, the regional risk indicator corresponding to the treatment area is set to 0;

[0018] Preferably, data analysis is performed on the supervision values to determine the degree of abnormality in the house planning of risky houses, and targeted risk prevention and control measures are implemented;

[0019] If the risk supervision value is 0, the building planning of the risk house is judged to be slightly abnormal, and the first risk prevention and control plan is implemented;

[0020] If the risk supervision value is not 0, the house planning of the risk house is judged to be severely abnormal, and the second risk prevention and control plan is implemented for it.

[0021] Preferably, a plurality of detection sensors are installed in all target areas of the renovated house, and the detection data of the plurality of detection sensors are counted and analyzed in real time;

BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] Figure 1 This is a flowchart of the operation of a building safety assessment risk situation awareness system based on a BIM model in the present invention. DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figure 1 As shown, the present invention is a building safety assessment risk situation awareness system based on a BIM model, comprising:

[0039] The building safety drawing recognition and processing module is used to obtain the house planning drawings of the house to be renovated, and perform risk identification analysis on the house planning drawings and the corresponding house planning standard drawings to obtain the regional risk identification set corresponding to the house to be renovated to which the house planning drawings belong. Based on the regional risk identification set, the planning status of the house planning drawings of the house to be renovated is dynamically prompted, and a targeted risk prevention and control plan is implemented; it includes:

[0040] Obtaining several target areas in a standard house planning drawing, as well as coordinate sets and target areas corresponding to the several target areas;

[0041] It should be noted that the target areas may specifically be several load-bearing walls and bay windows in a house; the coordinate sets and target areas corresponding to the target areas may be determined based on the BIM model of the actual house, and the target area is the area corresponding to the top view of the target area;

[0042] According to the coordinate sets corresponding to the target areas, the processing areas corresponding to the same coordinates in the house planning drawings are sequentially obtained, and the processing areas corresponding to the processing areas are obtained;

[0043] It should be explained that before a house is renovated, most people will design the house and then produce the corresponding house planning drawings. If the user does not find a design company to design it, but chooses to install it by themselves, then the existing manual inspection method can be used to check whether there is any illegal demolition at the renovation site.

[0044] In addition, different sizes of houses correspond to different standard house planning drawings, and different sizes of houses correspond to different target areas. Therefore, you can obtain the standard house planning drawings corresponding to the renovated house based on the specific house number.

[0045] Compare and judge the treated area of the treated region with the corresponding target area according to the coordinate set;

[0046] If the treatment area of the treatment area is the same as the corresponding target area, the regional risk indicator corresponding to the treatment area is set to 0;

[0047] Otherwise, the regional risk flag corresponding to the processing area is set to 1, and the processing area is marked as a risk processing area;

[0048] Understandably, the risk treatment area indicated that it had been illegally planned for demolition;

[0049] Sort and combine the regional risk identifications obtained by processing all target areas and the marked risk processing areas to obtain a set of regional risk identifications corresponding to the house planning drawings;

[0050] Conduct statistics and analysis on all risk treatment areas in the regional risk identification set;

[0051] If there is no risk treatment area in the regional risk identification set, it will be prompted that the planning status of the house planning drawings to which the regional risk identification set belongs is normal;

[0052] If there is a risk treatment area in the regional risk identification set, it will be prompted that the housing planning drawings belonging to the regional risk identification set are abnormal, and the houses to be renovated will be marked as risky houses;

[0053] It is understandable that when the status of house planning drawings is abnormal, there are different degrees of house planning abnormality. Therefore, through further data processing and analysis, targeted risk prevention and control can be implemented for renovated houses with different degrees of house planning abnormality.

[0054] When evaluating the degree of abnormality in the planning of risky houses, the formula Calculate the risk supervision value JG of the risk house; where N is the total number of risk treatment areas; S is the abnormal area impact value corresponding to all risk treatment areas, and the formula is: Calculated; where i is a different risk treatment area, i = 1, 2, 3, ..., N; N is a positive integer, representing the total number of risk treatment areas; s1i is the target area corresponding to the different risk treatment areas; s2i is the treatment area corresponding to the different risk treatment areas; S0 is the standard value of the abnormal area, which ranges from a real number greater than 0. The specific value is not limited and can be determined based on actual regulatory requirements or based on the median of the abnormal area impact values of all historical risk treatment areas; is the floor function;

[0055] Conduct data analysis on regulatory values to determine the degree of abnormality in the planning of risky houses and implement targeted risk prevention and control measures;

[0056] If the risk supervision value is 0, the building planning of the risk house is judged to be slightly abnormal, and the first risk prevention and control plan is implemented;

[0057] If the risk supervision value is not 0, the housing planning of the risk house is judged to be severely abnormal, and the second risk prevention and control plan is implemented;

[0058] Among them, the first risk prevention and control plan and the second risk prevention and control plan both specifically involve targeted on-site inspections of subsequent renovation construction in risky houses through manual inspections, and the frequency of on-site inspections in the second risk prevention and control plan is greater than that in the first risk prevention and control plan. Compared with the existing technical solutions in which personnel conduct indiscriminate on-site inspections of different house renovations, this can effectively improve the pertinence and reliability of safety inspections of renovated houses.

[0059] In the embodiment of the present invention, by performing risk identification analysis on the house planning drawings of the house to be renovated, dynamically prompting the planning status of the house planning drawings of the house to be renovated based on the analysis results, and implementing targeted risk prevention and control plans, it is possible to actively conduct building safety assessment risk situation awareness in the early stage of house decoration, thereby improving the active supervision effect of safety assessment and risk prevention and treatment effect in the early stage of house decoration.

[0060] The building safety construction supervision and processing module is used to proactively monitor and analyze renovation behavior risks in all target areas of a renovated house. Based on the analysis results, it dynamically verifies personnel involved in the renovations and uses personnel verification data to dynamically manage the supervision and analysis of renovation behavior risks. This module includes:

[0061] Install several detection sensors in all target areas of the renovated house, and perform real-time statistics and analysis on the detection data of several detection sensors;

[0062] The detection sensor is a vibration sensor, and the specific position of the detection sensor can be set by professionals in this field based on their work experience;

[0063] Acquire detection data corresponding to the detection sensor, and sequentially match identification item data corresponding to a plurality of identification items preset in the detection data with their corresponding identification item ranges;

[0064] Among them, several identification items include but are not limited to peak amplitude, duration and main frequency range; the specific values of the identification item range corresponding to different identification items can be determined based on the previous test data;

[0065] It is worth noting that there are multiple situations when the detection sensor detects data;

[0066] For example, only the target area is smashed, only the non-target area is smashed, and both the target area and the non-target area are smashed;

[0067] However, when only the target area is smashed or only the non-target area is smashed, there are differences in the identification data corresponding to several identification items;

[0068] Specifically, the peak amplitude is usually greater than 5g (unit of gravity acceleration) when the load-bearing wall is hit;

[0069] When a non-load-bearing wall is hit, it is usually less than 2g;

[0070] Duration: When the load-bearing wall is hit, it is short (single impact <50ms);

[0071] When a non-load-bearing wall is hit, it is longer (multiple consecutive hits > 200ms);

[0072] Main frequency range: When the load-bearing wall is hit, the low frequency is dominant (20-200Hz);

[0073] When a non-load-bearing wall is hit, the mid-high frequency (200-2000Hz) is dominant;

[0074] Therefore, by performing matching analysis on the identification item data corresponding to several identification items in the detection data, the risk identification effect can be effectively improved;

[0075] If the identification item data belongs to the corresponding identification item range, the corresponding identification item is marked as a valid identification item;

[0076] Otherwise, the corresponding identification item is marked as an invalid identification item;

[0077] Count the total number of valid identification items N. If N < N0, it is determined that the detection of the corresponding detection sensor is normal;

[0078] If N0≤N<N1, the detection of the corresponding detection sensor is determined to be slightly normal, and the renovated house where the detection sensor is located is marked as the first house, and personnel are prompted to go for verification and processing;

[0079] If N ≥ N1, the detection sensor is judged to have a severe abnormality, and the renovated house where the detection sensor is located is marked as the second house. At the same time, the power to the second house is cut off, and personnel are prompted to go for verification. N0 and N1 are different warning values, and both are positive integers. The specific values are not limited and can be customized according to the actual application requirements of the actual application scenario.

[0080] In the embodiment of the present invention, by actively monitoring and analyzing the risks of renovation behavior in all target areas of the renovated house, dynamically marking the renovated house based on the analysis results, and adaptively implementing targeted verification and processing solutions, the proactive perception of the building safety assessment risk situation during the house renovation process is improved;

[0081] When performing reliability analysis on the verification prompt effects of the first house and the second house, the total number of valid verifications and the total number of invalid verifications corresponding to the first house and the second house are counted respectively, and the formula Calculate and obtain the prompt reliability values αk corresponding to the first house and the second house; where k is 1 and 2, which are the verification prompts of the first house and the verification prompts of the second house, respectively; n1k is n11 and n12, which are the total number of valid verifications of the first house and the total number of valid verifications of the second house, respectively; n2k is n21 and n22, which are the total number of invalid verifications of the first house and the total number of invalid verifications of the second house, respectively; pk is p1 and p2, which are the first prompt reliability warning value of the verification prompt of the first house and the second prompt reliability warning value of the verification prompt of the second house, respectively. The specific values are not limited and can be customized according to the actual application requirements of the actual application scenario. For example, when the actual application requirements are high, the value can be 1;

[0082] If the prompt reliability value is greater than or equal to 0, the prompt corresponding to the house to which the prompt belongs is reliable;

[0083] Otherwise, it indicates that the prompt corresponding to the house is unreliable, and the parameters N0 or N1 when analyzing the mark of the house are adjusted;

[0084] Among them, when adjusting the parameters of N0 or N1 when the house is analyzed and marked, specifically, N0 when the first house is marked and N1 when the second house is marked can be increased by 1 respectively.

[0085] In the embodiment of the present invention, by actively supervising and analyzing the risks of decoration behavior in all target areas in the renovated house, and dynamically verifying the personnel of the renovated house based on the analysis results, and using the personnel verification processing data to dynamically manage the supervision and analysis of the risks of decoration behavior, active risk supervision identification and processing are realized from the decoration process of the renovated house, and the implementation parameters of the active risk supervision identification plan are actively optimized, which can effectively improve the diversity and reliability of the active supervision analysis of the risk situation awareness of the building safety assessment.
