Description

Technical Field

[0001] The present invention relates to the technical field of real estate registration data integration processing, and in particular to a business data integration method and system for real estate registration. Background Art

[0002] With the acceleration of urbanization, real estate transactions and development activities are becoming more frequent, and the limitations of the traditional real estate registration system are gradually becoming apparent. At present, the conventional real estate registration system mainly records the basic attributes of real estate, such as property information, transaction records, and land use, etc., and it is difficult to conduct a comprehensive analysis and quantification of the multi-dimensional value of real estate. This method makes the real estate registration information relatively single and lacks effective evaluation of real estate development potential and market adaptability.

[0003] In the actual development and investment decision-making process, the value and development feasibility of real estate are affected by many factors, including terrain conditions, available land area, environmental quality, infrastructure convenience, and regional market economy. However, the existing real estate registration system usually lacks data integration and analysis methods for these key factors, resulting in certain limitations in registration information in supporting development planning and investment decisions.

[0004] In addition, the traditional real estate registration system lacks standardized and quantitative data models, and cannot achieve cross-regional and cross-property comparison and optimization. This not only limits the role of real estate data in resource allocation, but also to a certain extent affects the scientific decision-making of developers and investors in planning and investment.

[0005] The limitations of existing technologies include at least the following problems. First, in traditional real estate registration business, people usually only focus on basic real estate identification and property rights certification information, lack in-depth analysis of real estate development potential, and find it difficult to systematically evaluate real estate development status and market value. This practice leads to the singleness of registration data, resulting in a lack of sufficient supporting information when making real estate development and transaction decisions, which in turn may lead to improper resource utilization or missed market opportunities. Secondly, in the process of data integration, existing methods often lack a comprehensive analysis and quantification of the current status of real estate, resulting in only one-sided static information, making it difficult to fully reflect the dynamic development potential and risks of real estate. This limitation may cause delays or errors in development and planning strategies, resulting in unsatisfactory returns on investment, or even high risks in the development process, increasing the cost of real estate development and utilization. Summary of the invention

[0017] The present invention has the following beneficial effects: (1) This business data integration method for real estate registration constructs a comprehensive development index by calculating multiple indicators such as terrain development index, land area development index, environmental quality index, infrastructure convenience index and regional market economy index, and systematically quantifies the development potential of real estate. Unlike the previous method of relying solely on manual evaluation or subjective judgment, the quantitative indicators can more objectively and fairly reflect the comprehensive value and development potential of real estate. The development rating levels are divided based on these quantitative indicators, which is convenient for comparing the development value of different real estates and provides a scientific decision-making basis for developers and investors, which helps to improve the rational use of real estate and the efficiency of resource allocation.

[0018] (2) This business data integration method for real estate registration, based on the initial real estate registration data table, integrates multi-dimensional indexes such as terrain, area, environment, infrastructure, and market economy to ultimately form a comprehensive real estate registration data table, which greatly improves the management efficiency and practicality of the data. It integrates and stores various indexes and development rating levels, which not only facilitates subsequent query and analysis, but also provides more systematic and reliable data support for government departments, developers and investors. At the same time, based on the preset development rating level rules, the development level of real estate can be quickly determined, thereby achieving refined management of real estate.

[0019] (3) This business data integration method for real estate registration makes the registration information more comprehensive and detailed by introducing multi-dimensional data such as terrain, environment, infrastructure and regional economy. By acquiring and integrating terrain status data, land area development status data, environmental status data, infrastructure convenience data and regional market economic data, it can evaluate the value of real estate from multiple angles, provide more valuable reference information for development and investment decisions, and effectively make up for the limitations of traditional real estate registration information.

[0020] (4) The business data integration system for real estate registration has a modular design structure, which not only reduces the degree of coupling between the functional modules within the system, making it easier to maintain and update, but also allows the system to flexibly expand and optimize its functions. For example, if new data types need to be introduced in the future, it only needs to add corresponding data acquisition modules and analysis modules to the system to expand the existing analysis functions without rebuilding the entire system architecture. This flexibility significantly improves the adaptability of the system, enabling it to be continuously optimized as policies, technologies and data sources change, providing good technical support for the continuous improvement of real estate registration business.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The embodiment of the present application solves the problem that in traditional real estate registration business, only basic real estate identification and property certificate information is usually focused on, and there is a lack of in-depth analysis of real estate development potential, making it difficult to systematically evaluate the development status and market value of real estate through a business data integration method and system for real estate registration. This practice leads to the singleness of registration data, resulting in a lack of sufficient supporting information when making real estate development and transaction decisions, which may lead to improper resource utilization or missed market opportunities. Secondly, in the data integration process, existing methods often lack a comprehensive analysis and quantification of the current status of real estate, resulting in only one-sided static information, making it difficult to fully reflect the dynamic development potential and risks of real estate. This limitation can easily cause delays or errors in development and planning strategies, resulting in unsatisfactory return on investment, and even facing high risks in the development process, increasing the cost of real estate development and utilization.

[0026] The overall idea of ​​the problem in the embodiment of this application is as follows: First, the basic information of the real estate to be registered is obtained, including identification information, property certificate information, land use information and transaction record information, and this information is pre-processed to ensure the integrity and accuracy of the data. Based on the pre-processed basic information, the initial registration data table of the real estate is established. Then, the current status information of the real estate is further obtained, including terrain status data (slope, etc.), land area development status data (total area, protection area, remaining years, etc.), environmental status data (air quality, water quality, noise, greening, etc.), infrastructure convenience data (network coverage, water supply and power reliability, etc.) and regional market economic data (surrounding housing prices, population growth rate, economic growth rate, etc.). Based on the above status data, the terrain development index, land area development index, environmental quality index, infrastructure convenience index and regional market economic index are calculated respectively. Then, these indices are comprehensively analyzed to obtain the comprehensive development index of the real estate to be registered. According to the preset development scoring grade rules, the development scoring grade of the real estate to be registered is divided, and all indexes and scoring grades are integrated into the initial registration data table. Finally, the real estate comprehensive registration data table is formed and stored for subsequent query and analysis.

[0027] See also Figure 1The embodiment of the present invention provides a technical solution: a business data integration method for real estate registration, comprising the following steps: in the real estate registration business, data usually comes from multiple business departments, including the Natural Resources Bureau (responsible for land and natural resources data), the Tax Bureau (providing tax-related data), and the Housing and Construction Bureau (managing real estate data, etc.), respectively obtaining the identification information, property certificate information, land use information, and transaction record information of the real estate to be registered from the multiple business departments, and pre-processing them; based on the identification information, property certificate information, land use information, and transaction record information of the real estate to be registered after pre-processing, establishing a real estate initial registration data table; obtaining the current status information of the real estate to be registered, the current status information includes terrain status data, land area development status data, environmental status data, infrastructure convenience data, Regional market economic data; conduct a comprehensive analysis on the current status information of the real estate to be registered to obtain the terrain development index, land area development index, environmental quality index, infrastructure convenience index, and regional market economic index of the real estate to be registered; conduct a comprehensive analysis on the terrain development index, land area development index, environmental quality index, infrastructure convenience index, and regional market economic index of the real estate to be registered to obtain the comprehensive development index of the real estate to be registered, and divide the development scoring level of the real estate to be registered based on the preset development scoring level rules; integrate the terrain development index, land area development index, environmental quality index, infrastructure convenience index, regional market economic index, comprehensive development index, and development scoring level of the real estate to be registered into the real estate initial registration data table to obtain the real estate comprehensive registration data table, and store it.

[0028] Identification information includes unique real estate identification, plot number, etc.

[0029] The property rights certification information specifically includes the current owner’s name, ID number, property registration number, etc.

[0030] Land use information includes land use, etc.

[0031] Transaction record information includes historical transaction time, historical transaction price, historical buyer and seller information, etc.

[0032] Preprocessing includes data cleaning and data verification, where the data cleaning process is as follows: Deduplication processing: Real estate data comes from multiple sources and usually contains duplicate entries. For example, the same real estate is often stored in different formats or fields in different business departments. It is necessary to match data and deduplicate duplicate records through real estate ID, property owner information, address, etc.

[0033] Data standardization: Unify the format of data, especially for fields such as date (unified year-month-day format), address (use standard address code), name (remove redundant characters such as spaces and punctuation), so that data from different departments can be compatible with each other.

[0034] Noise data processing: Delete irrelevant fields and process blank values ​​and outliers in the data. You can clean up the noise data and improve the data availability by filling in the data (such as the mean or median) or deleting records with a large amount of missing information.

[0035] The data verification process is as follows: Integrity check: Check whether the necessary fields of each record (such as real estate ID, owner, location, etc.) are missing to ensure the integrity of the data.

[0036] Accuracy verification: Verify the accuracy of key data by comparing it with other authoritative data sources. For example, verify the identity of the property owner through personal ID number to ensure the authenticity and validity of property information.

[0037] Logical consistency check: Ensure that the data is logically reasonable. For example, check whether the buyer and seller in the transaction record actually exist, whether the use of the real estate complies with the local land use planning, etc.

[0038] The steps to create the real estate initial registration data table are as follows: According to business needs, build a standardized metadata model that includes the fields required for real estate registration, define the attributes of each field (data type, field length, mandatory, etc.) and the relationship between fields, for example, define fields such as real estate ID (string type, length 10), owner (text type, length 50), location (text type, length 100), and purpose (enumeration type), and define the field types and constraints in detail.

[0039] Use the primary key and foreign key in the relational database to store real estate information in multiple tables, such as "real estate basic information table", "property owner information table", "land information table", "transaction record table", etc., to structure the data for easy query and maintenance.

[0040] Real estate registration data is classified according to different business needs and uses. For example, land data includes information such as land number and purpose; house data includes property owner information, house area, house purpose, etc.; transaction data includes transaction amount, transaction time, transaction party, etc.

[0041] Add label attributes to the data to facilitate quick retrieval and analysis of the data. For example, add labels such as "agricultural land" and "construction land" to land data, and add labels such as "individual" and "company" to property owner data. This classification and labeling operation can facilitate subsequent data mining and statistical analysis.

[0042] Using the real estate unit number (or real estate ID) as the primary key for different data sources makes it easier to merge relevant information about the same real estate from different sources. For data that lacks a real estate ID, other fields, such as the combination of property owner + address information, can be used for unique matching.

[0043] Use automated matching algorithms to merge data records from different data sources by matching primary keys or key fields. For example, match address fields that may have format differences based on similarity calculations of address strings.

[0044] Define association rules between data, such as the one-to-many relationship between real estate and property owners (one real estate may have multiple property owners), and the one-to-many relationship between transaction records and real estate (one real estate may have multiple transaction records).

[0045] Integrate related data into a whole according to defined rules. For example, link each transaction record of real estate to the transaction history under the real estate unit number to ensure the integrity and consistency of the data.

[0046] Data priority determination: For conflicting information in real estate data (such as differences in property owner names), conflicts can be handled based on the data source priority or the chronological order of data updates. For example, data provided by authoritative departments (such as the Natural Resources Bureau) can be used as the main basis, and the latest data shall prevail.

[0047] For situations where there are serious conflicts that are difficult to resolve with automated rules, a manual review mechanism is established to manually check and confirm the conflicting data to ensure the ultimate accuracy of the data.

[0048] The specific steps to obtain the real estate comprehensive registration data table are as follows: Similarly, the primary key and foreign key in the relational database are used to divide the current status information of the real estate into multiple tables for storage, such as the "terrain status information table", the "land area development status information table", etc. The land area development status information table includes land area development status data (total available land area value, protected area land area value, total land area value, remaining land use years value), land area development index, and the contents of the remaining information tables are established and stored in this way.

[0049] The preset development scoring levels include, but are not limited to, the following examples: Grade A (extremely high development potential): Very suitable for development and in excellent conditions.

[0050] Class B (high development potential): suitable for development, with good conditions.

[0051] Grade C (medium development potential): average development conditions.

[0052] Grade D (low development potential): Development conditions are poor and there are certain constraints.

[0053] Grade E (extremely low development potential): Not suitable for development and has low development potential.

[0054] When the comprehensive development index is ≥4.5, the real estate development rating level is A (extremely high development potential).

[0055] When 3.5≤comprehensive development index<4.5, the real estate development rating level is B (high development potential).

[0056] When 2.5≤comprehensive development index<3.5, the real estate development rating level is C (medium development potential).

[0057] When 1.≤comprehensive development index<2.5, the development rating level of the real estate is D (low development potential).

[0058] When the comprehensive development index is <1.5, the real estate development rating level is E (extremely low development potential).

[0059] The terrain status data specifically include the current land slope values ​​of several terrain locations; the land area development status data specifically include the total available land area value, the protected area land area value, the total land area value, and the remaining land use period value; the environmental status data specifically include the concentration value of each air pollutant, the value of each water quality index, the value of each soil pollutant content, the actual noise level value, and the greening area value; the infrastructure convenience data specifically include the network coverage rate, the historical annual power outage time value, the historical water supply interruption time value, the number of infrastructure within the set range, and the straight-line distance value to each infrastructure; the regional market economic data specifically include the average housing price within the set range within the set area, the population growth rate value, and the economic growth rate value.

[0060] The current land slope value is obtained by using high-precision measuring equipment such as total station, laser rangefinder, terrain slope meter, etc.

[0061] The total available land area value, protected area land area value, and total land area value can be obtained through the real estate registration department or natural resources department.

[0062] The remaining land use period value is obtained from the real estate registration certificate or land use certificate.

[0063] The concentration value of each air pollutant obtains specific pollutant concentration data from the environmental protection department or the air quality monitoring station in the urban area, and the types of air pollutants include but are not limited to the following examples: PM2.5 and PM10, sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), ozone (O2) and volatile organic compounds (VOCs), carbon dioxide (CO2), methane (CH4), etc.

[0064] Each water quality index value is usually obtained from water quality parameters in a water quality monitoring station.

[0065] The content value of each soil pollutant is obtained by sampling the soil and sending it to the laboratory for testing, and the types of soil pollutants include but are not limited to the following examples: heavy metal pollutants (such as lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), etc.), organic pollutants (such as pesticide residues, petroleum pollutants, volatile organic compounds (VOCs), etc.), other pollutants (such as nitrogen, phosphorus, fluorine, etc.), etc.

[0066] The actual noise level value is measured using professional noise measuring instruments (such as decibel meters) at different time periods to obtain noise data.

[0067] The green area value is calculated through satellite images or drone aerial photography combined with GIS software to calculate the green coverage area in the area.

[0068] The historical annual power outage duration values ​​were obtained from the local power company.

[0069] The historical water supply interruption time values ​​are obtained from the local water supply company.

[0070] The number of infrastructure facilities within the set range can be obtained by searching using applications such as Baidu Maps and Amap.

[0071] The straight-line distance to each infrastructure was measured using GIS software.

[0072] The average house price within a set range within a set area specifically refers to the average house price within a radius of 5 kilometers with the set area as the center.

[0073] Specifically, the specific formula for calculating the comprehensive development index of the real estate to be registered is as follows: ;in, is the comprehensive development index of the real estate to be registered. The terrain development index of the real estate to be registered. is the terrain development coefficient of the real estate to be registered, The land area development index for the real estate to be registered. is the land area development coefficient of the real estate to be registered, is the environmental quality index of the real estate to be registered, is the environmental quality coefficient of the real estate to be registered, The infrastructure convenience index of the real estate to be registered, is the infrastructure convenience coefficient of the real estate to be registered, is the regional market economic index of the real estate to be registered, is the regional market economic coefficient of the real estate to be registered, , is a natural constant.

[0074] It needs to be explained that , , , , The specific calculation process is as follows: obtain the historical terrain development index, historical land area development index, historical environmental quality index, historical infrastructure convenience index, and historical regional market economy index of the real estate to be registered each year, and perform mean analysis (the calculation methods of these indices are consistent with the calculation methods of the terrain development index, land area development index, environmental quality index, infrastructure convenience index, and regional market economy index), obtain the mean of the historical terrain development index, the mean of the historical land area development index, the mean of the historical environmental quality index, the mean of the historical infrastructure convenience index, and the mean of the historical regional market economy index of the real estate to be registered, and perform sum and proportion analysis, and the analysis result is the corresponding coefficient.

[0075] In this implementation scheme, by calculating the average of the terrain development index, land area development index, environmental quality index, infrastructure convenience index and regional market economy index for each year in history, the system can effectively filter out the impact of short-term data fluctuations on the comprehensive development index. This mean analysis method can smooth out accidental extreme values, making the calculated comprehensive development index more stable and reliable. For long-term development planning, this stability can help developers and decision makers better grasp the true value of real estate and avoid making unfavorable decisions due to short-term data fluctuations. By calculating the average of historical data, this method combines the comprehensive development potential of real estate with its historical development trend, providing a more continuous indicator. The coefficient obtained based on the historical average is more representative because it not only reflects The current data also takes into account the past indicator levels, making the comprehensive development index more in line with the actual development potential of real estate. This continuity and consistency can better support the prediction of the future development of real estate and provide more accurate market value estimates. The historical average and current data are summed and analyzed to obtain various development coefficients that reflect the long-term comprehensive performance of real estate in all aspects. Compared with using only the current year's data, this percentage analysis based on historical averages is more scientific, and can avoid underestimating or overestimating the development value of real estate due to abnormal fluctuations in the short term. The comprehensive development index obtained in this way provides decision makers with a more scientific and rational basis in real estate development, transactions and management, which helps to formulate more feasible development plans and improve the efficiency of reasonable allocation of real estate resources.

[0076] Specifically, Figure 2 As shown, the specific steps for obtaining the terrain development index of the real estate to be registered are as follows: read the current land slope values ​​of several terrain location points of the real estate to be registered and perform a comprehensive analysis to obtain the current land slope analysis value of the real estate to be registered; obtain the reference slope value of the developed land, and perform a comprehensive analysis in combination with the current land slope analysis value of the real estate to be registered to obtain the terrain development index of the real estate to be registered.

[0077] The specific formula for calculating the current land slope analysis value and terrain development index of the real estate to be registered is as follows: ;in, is the current land slope analysis value of the real estate to be registered, For the immovable property to be registered The current land slope value of each terrain location point, For the immovable property to be registered The weight coefficient of the current land slope value at each terrain location point, For the immovable property to be registered The current land slope value of each terrain location point, For the immovable property to be registered The weight coefficient of the current land slope value at each terrain location point, , =1, 2, 3, ..., , is the number of terrain location points, The terrain development index of the real estate to be registered. Reference slope values ​​for developed land.

[0078] It needs to be explained that , The specific calculation steps are as follows: , The current land slope values ​​of the topographic location points are summed and analyzed to obtain the first The current land slope and value are then , The current land slope values ​​of the topographic location points are respectively related to the first The current land slope and value are analyzed by ratio, and the analysis result is the corresponding weight coefficient.

[0079] The reference slope value of the development land is the ideal slope for construction and development, for example, 5% in this example, which is a common building standard.

[0080] In this implementation scheme, by reading the slope values ​​of several terrain location points one by one and conducting a comprehensive analysis thereof, the terrain characteristics of the entire plot can be accurately reflected. This method not only calculates the slope value of each location point, but also introduces a weight coefficient, so that the terrain development index can better reflect the slope differences at different location points. Especially in terrain with ups and downs, this method of weight allocation can avoid misjudgment caused by relying solely on the average slope, more realistically reflect the development difficulty and suitability of the terrain, and help plan and design more scientific development plans. In the process of calculating the weight coefficient, an objective weight is assigned to each location point by performing a ratio analysis of the slope value of each location point and the total slope value of the group of location points. This weight is based on the actual slope differences at each location point, which not only eliminates artificial The influence of subjective judgment also ensures that the calculation results of the terrain development index are highly objective. Through this quantitative processing method, the system can better capture the real characteristics of the terrain, making the calculation results more accurate and valuable for reference. This method uses 5% as the reference slope value for developed land, which is an ideal slope standard commonly used in the fields of construction and development. By comparing the current land slope analysis value of the real estate to be registered with the ideal slope value, the terrain development index is calculated, which is convenient for developers to quickly determine whether the terrain meets the development standards. This standardized reference value not only improves the practicality of the calculation, but also makes the index more universal. It is suitable for different types of terrain assessments, which helps to make scientific decisions in the planning and design stages and improve the feasibility and benefits of real estate development.

[0081] Specifically, the specific steps for obtaining the area development index of the real estate to be registered are as follows: read the total available land area value, the protected area land area value, the total land area value, and the remaining land use period value of the real estate to be registered, and conduct a comprehensive analysis to obtain the area development index of the real estate to be registered. The calculation formula is as follows: ;in, is the area development index of the real estate to be registered, is the total available land area of ​​the real estate to be registered, is the land area value of the protected area of ​​the real estate to be registered, is the total land area of ​​the real estate to be registered, The remaining land use period value of the immovable property to be registered. is a non-zero real number used to smooth the impact of the term, so that as the remaining term increases, the index weight gradually tends to be stable. In this embodiment, the value is 10. At this time, the specific formula for calculating the terrain development index of the real estate to be registered is: .

[0082] If the total area of ​​available land is large, the area of ​​protected land is small, and the remaining useful life is long, the land development index is high, indicating greater development potential.

[0083] If the land area of ​​the protected area is large or the remaining useful life is short, the land development index will be correspondingly reduced, indicating that the development potential is small.

[0084] It should be explained that the total available land area value is the area of ​​the plot that can be used without obstacles.

[0085] The protected area land area value is the area that cannot be used for construction or other activities due to protection restrictions (such as environmental regulations), building codes, or other factors, such as wetland protection areas and wildlife habitat protection areas.

[0086] In this implementation scheme, the method uses two indicators, "total available land area" and "protected area land area" to distinguish the actual developable area from the protected restricted area. The total available land area reflects the part of the plot that can be developed and is barrier-free, while the protected area area represents the part that cannot be used for construction due to laws or environmental protection regulations. Incorporating these two indicators into the calculation of the area development index makes the calculation result more accurately reflect the actual development potential of the real estate, which helps developers to fully understand the development value and utilization rate of the plot when making decisions. The remaining land use period directly affects the sustainability and investment value of the development project. By introducing the period into the calculation of the area development index and setting a smoothing A constant can make the index gradually tend to be stable as the remaining years increase. This processing method can avoid the excessive impact of the land use period on the development value in the short term, so that the calculation results can not only reflect the long-term development potential, but also reasonably evaluate the term of land use, and provide a more stable and long-term reference for development and investment decisions. This method not only takes into account the physical area data of the plot, but also integrates the restrictive factors of law and environmental protection (such as the area of ​​protected areas), adding the dimensions of compliance and sustainability to the evaluation of development value. The protected area area indicator ensures that the development plan complies with environmental and building regulations, avoiding potential legal or environmental risks caused by ignoring protected areas.

[0087] Specifically, the specific steps for obtaining the environmental quality index of the real estate to be registered are: obtaining the reference value of each air pollutant concentration, each water quality index reference value, each soil pollutant content reference value, and noise level reference value of the real estate to be registered; conducting a comprehensive analysis of each air pollutant concentration value and each air pollutant concentration reference value, each water quality index value and each water quality index reference value, each soil pollutant content value and each soil pollutant content reference value, the actual noise level value and the noise level reference value, the greening area value and the total land area value, to obtain the air quality index, water quality index, soil quality index, noise quality index, and greening coverage index of the real estate to be registered; conducting a comprehensive analysis of the air quality index, water quality index, soil quality index, noise quality index, and greening coverage index of the real estate to be registered to obtain the environmental quality index of the real estate to be registered.

[0088] The specific formula for calculating the air quality index, water quality index, soil quality index, noise quality index, green coverage index and environmental quality index of the real estate to be registered is: ;in, is the air quality index of the real estate to be registered, For the immovable property to be registered The concentration of air pollutants, For the immovable property to be registered Reference values ​​of air pollutant concentrations, For the immovable property to be registered The weighting coefficient of the concentration value of the air pollutant is =1, 2, 3, ..., , is the number of air pollutants, is the water quality index of the real estate to be registered, For the immovable property to be registered Water quality index values, For the immovable property to be registered Reference values ​​of water quality indicators: For the immovable property to be registered The weighting coefficient of the water quality index value is =1, 2, 3, ..., , is the number of water quality indicators, is the soil quality index of the real estate to be registered, For the immovable property to be registered The content of soil pollutants, For the immovable property to be registered Reference values ​​of soil pollutant content, For the immovable property to be registered The weighting coefficient of the soil pollutant content value is =1, 2, 3, ..., , is the number of soil pollutants, is the noise quality index of the real estate to be registered, is the actual noise level value of the real estate to be registered, is the reference value of the noise level of the real estate to be registered, is the green coverage index of the real estate to be registered, is the green area value of the real estate to be registered, is the total land area of ​​the real estate to be registered, is the environmental quality index of the real estate to be registered, is the proportional coefficient of the air quality index of the real estate to be registered, is the proportional coefficient of the water quality index of the immovable property to be registered, is the proportional coefficient of the soil quality index of the immovable property to be registered, is the proportional coefficient of the sound quality index of the real estate to be registered, is the proportional coefficient of the green coverage index of the real estate to be registered, , is a natural constant.

[0089] It needs to be explained that The specific calculation process is: sum and analyze the reference values ​​of each air pollutant concentration of the immovable property to be registered, obtain the air pollutant concentration and value of the immovable property to be registered, and then The ratio analysis of the concentration value of each air pollutant is performed with the sum of the concentrations of air pollutants, and the analysis result is the corresponding weighting coefficient.

[0090] The specific calculation process is: sum and analyze the reference value of each water quality index of the immovable property to be registered, obtain the reference and value of the water quality index of the immovable property to be registered, and then The water quality index values ​​are compared with the water quality index reference values, and the analysis result is the corresponding weighted coefficient.

[0091] The specific calculation process is: sum and analyze the reference values ​​of each soil pollutant content of the immovable property to be registered, obtain the reference and value of the soil pollutant content of the immovable property to be registered, and then The soil pollutant content values ​​of the species are compared with the reference and value of the soil pollutant content, and the analysis result is the corresponding weighted coefficient.

[0092] , , , , The specific calculation process is as follows: standardize the air pollutant concentration and value, water quality index reference and value, soil pollutant content reference and value, noise level reference value, and total land area value of the real estate to be registered (i.e., remove the unit), and sum and analyze them after standardization to obtain the environmental sum value, and then perform proportion analysis on the air pollutant concentration and value, water quality index reference and value, soil pollutant content reference and value, noise level reference value, and total land area value of the real estate to be registered after the standardized treatment, respectively, and the environmental sum value, and the analysis result is the corresponding proportional coefficient.

[0093] Air pollutants such as PM2.5, PM10, SO2, NO2, O3, CO, etc.

[0094] Water quality indicators such as pH value, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total nitrogen, total phosphorus, etc.

[0095] Soil pollutants such as heavy metals, organic matter, etc.

[0096] The actual noise level value is obtained by obtaining the historical noise level values ​​during the day and night every day and performing mean analysis.

[0097] In this implementation plan, the method refines the acquisition and analysis of environmental data from five aspects, namely air quality, water quality, soil quality, noise level and green coverage. By obtaining the specific concentration values ​​of each air pollutant, water quality index and soil pollutant, and then weighting them to generate a single environmental index, each environmental factor can be independently quantified. This not only ensures the accuracy of the environmental quality index, but also makes the assessment of environmental suitability more scientific. Especially in complex environments, this multi-dimensional assessment method can effectively identify the potential impact of the environment on development and provide more accurate environmental suitability data for real estate development. By standardizing the air pollutant concentration values, water quality index values, soil pollutant content values, noise level values ​​and green area values, a proportion analysis is performed. , which enables comparison of various environmental factors on the same scale and avoids deviations caused by direct calculation of data of different dimensions. Standardization ensures the objectivity of the data. The proportion analysis reflects the relative impact of various environmental factors on the overall environmental quality of real estate. This scientific quantification process can eliminate the interference of units, making the environmental quality indexes of different real estate comparable, which helps developers to effectively compare and optimize different projects. The actual noise level data is obtained through the mean analysis of the historical daytime and nighttime noise levels every day, which can more stably reflect the long-term noise conditions and avoid the interference of short-term abnormal noise. At the same time, the concentration values ​​of air, water and soil pollutants are also calculated with weighted coefficients respectively to ensure the comprehensive impact of long-term accumulated environmental data on the environmental quality index.

[0098] Specifically, the specific steps for obtaining the infrastructure convenience index of the real estate to be registered are as follows: perform mean analysis on the historical annual power outage time values, historical water supply interruption time values, and the straight-line distance values ​​from each infrastructure within a set range (for example, a circular range with a radius of 5 kilometers) of the real estate to be registered, and obtain the historical average annual power outage time value, historical average annual water supply interruption time value, and the average straight-line distance value of the real estate to be registered; perform comparative analysis on the historical annual power outage time value, historical water supply interruption time value, and the straight-line distance value from each infrastructure within the set range of the real estate to be registered, and obtain the maximum historical power outage time value, historical water supply interruption time value, and maximum straight-line distance value of the real estate to be registered; obtain the value of the real estate to be registered. The reference number of infrastructure facilities for registering real estate; conduct a comprehensive analysis of the reference number of infrastructure facilities for real estate to be registered and the number of infrastructure facilities within the set range, the average straight-line distance and the maximum straight-line distance of the real estate to be registered, the historical average annual power outage time and the maximum historical power outage time of the real estate to be registered, and the historical average annual water supply interruption time and the maximum historical water supply interruption time of the real estate to be registered to obtain the infrastructure index, straight-line distance index, power outage time index and water supply interruption time index of the real estate to be registered; conduct a comprehensive analysis of the network coverage rate of the real estate to be registered in combination with the infrastructure index, straight-line distance index, power outage time index and water supply interruption time index to obtain the infrastructure convenience index of the real estate to be registered.

[0099] The specific formulas for calculating the infrastructure index, straight-line distance index, power outage time index, water supply interruption time index, and infrastructure convenience index of the real estate to be registered are as follows: ;in, is the infrastructure index of the real estate to be registered, The number of infrastructure facilities within the set range of the real estate to be registered. The reference number of infrastructure facilities for the real estate to be registered. is the straight-line distance index of the real estate to be registered, is the average straight-line distance of the real estate to be registered, is the maximum straight-line distance of the real estate to be registered, is the power outage time index of the real estate to be registered, is the historical average annual power outage time of the real estate to be registered, is the maximum historical power outage time of the real estate to be registered, is the water supply interruption time index of the immovable property to be registered, is the historical average annual water supply interruption time of the real estate to be registered, is the maximum historical water supply interruption time of the real estate to be registered, The infrastructure convenience index of the real estate to be registered, is the network coverage rate of the real estate to be registered, is the infrastructure coefficient of the immovable property to be registered, is the network coverage coefficient of the immovable property to be registered, is the straight-line distance coefficient of the real estate to be registered, is the power outage time coefficient of the real estate to be registered, is the water supply interruption time coefficient of the real estate to be registered, .

[0100] It needs to be explained that infrastructure specifically refers to medical facilities, educational facilities (such as schools and libraries), shopping centers, public transportation stations, public facilities (such as parks and squares), etc. within the area where the real estate is located. The reference number of infrastructure is obtained by obtaining the number of facilities in several city centers and calculating the average.

[0101] Network coverage can be obtained through Google Maps, Baidu Maps and Amap, which usually provide relevant information about mobile network coverage and can query the network coverage of a certain area. It can also be obtained from the measurement data of network coverage provided by some specialized network monitoring service companies, such as OpenSignal and Ookla. These services are usually based on the actual usage data of user devices, with wide coverage and good real-time performance. , , , , The specific calculation process is as follows: the reference number of infrastructure facilities to be registered, the average straight-line distance, the historical average annual power outage time, and the historical average annual water supply interruption time of the real estate to be registered are standardized (i.e., the unit is removed), and the standardization is followed by sum analysis with the network coverage rate to obtain the infrastructure sum value, and then the network coverage rate, the reference number of infrastructure facilities to be registered after standardization, the average straight-line distance, the historical average annual power outage time, and the historical average annual water supply interruption time are respectively ratio analyzed with the infrastructure sum value, and the analysis result is the corresponding coefficient.

[0102] In this implementation scheme, this method combines multiple data factors such as the number of infrastructure, straight-line distance, power outage and water supply interruption time when calculating the infrastructure convenience index. Each factor can affect the actual convenience of real estate use, and the multi-dimensional data combination can more comprehensively reflect the distribution and quality of infrastructure in the region. For example, the number and distance of infrastructure reflect the density and accessibility of resources, while power outage and water supply data reflect the stability of infrastructure. Taking these factors into consideration not only increases the accuracy of the index, but also can provide decision makers with a more objective and comprehensive convenience evaluation. By standardizing the number of infrastructure references, the average straight-line distance, the historical average annual power outage time, and the average annual water supply interruption time, the unit differences of the data are eliminated, ensuring indicators of different dimensions. Calculations are performed at the same scale. This standardization method not only ensures the fairness of various data in the convenience calculation, but also improves the comparability of the infrastructure convenience index, so that the convenience levels of real estate can be objectively compared. This data standardization process avoids the deviation caused by differences in units and orders of magnitude, making the index calculation more reliable and robust. In this embodiment, areas with high convenience such as the city center are used as references for the number of infrastructure facilities. The communication convenience in the area is quantified in combination with the network coverage rate to form a relative standard. By obtaining the number of facilities in multiple city centers and calculating their average, the reference number of infrastructure facilities is set, so that the convenience of the real estate to be evaluated can be benchmarked against a higher urban basic level. The convenience index obtained after combining the network coverage rate can more intuitively evaluate the service level in the area.

[0103] Specifically, the specific steps for obtaining the regional market economic index of the real estate to be registered are as follows: obtain the reference value of the surrounding housing price, the reference value of the population growth rate, and the reference value of the economic growth rate within the set area of ​​the real estate to be registered; conduct a comprehensive analysis of the average housing price within the set range of the real estate to be registered and the reference value of the surrounding housing price, the population growth rate value and the population growth rate reference value, and the economic growth rate value and the economic growth rate reference value, to obtain the regional market economic index of the real estate to be registered, and the calculation formula is as follows: ;in, is the regional market economic index of the real estate to be registered, is the average housing price within the set area of ​​the real estate to be registered. It is the reference value of the surrounding housing prices within the set area of ​​the real estate to be registered. is the price coefficient of the real estate to be registered, is the population growth rate value in the set area of ​​the real estate to be registered, The reference value of the population growth rate in the set area of ​​the real estate to be registered. is the population growth coefficient of the immovable property to be registered, is the economic growth rate value in the set area of ​​the real estate to be registered, It is the reference value of the economic growth rate in the set area of ​​the real estate to be registered. is the economic growth coefficient of the real estate to be registered, .

[0104] It should be explained that the average house price in the set range can be queried through the real estate trading platform for the house price in the area near the real estate. The house price is the average house price in the set range at the current point in time, and the reference value of the surrounding house price is obtained by average analysis of the historical house prices in the area over several years.

[0105] The population growth rate value can be obtained from the annual statistical report of the local statistics bureau, which will contain the current year's population change data, while the population growth rate reference value is the average of the annual population change data of the past few years.

[0106] The economic growth rate is measured by the GDP growth rate, which is published in the economic report of the local statistics bureau. The report provides the annual GDP growth rate, and the reference value of the economic growth rate is the average calculation result of the historical annual GDP growth rate in the past few years.

[0107] , , The specific calculation process is: standardize the reference value of surrounding housing prices, reference value of population growth rate, and reference value of economic growth rate within the set area of ​​the real estate to be registered (i.e., remove the unit), and perform sum analysis after standardization to obtain the market economic sum value, and then perform ratio analysis with the market economic sum value of the reference value of surrounding housing prices, reference value of population growth rate, and reference value of economic growth rate within the set area of ​​the real estate to be registered after standardization, and the analysis result is the corresponding coefficient.

[0108] The specific implementation example of calculating the regional market economic index of the real estate to be registered is as follows, and the following data are available: The average housing price within the current set range is: 12,000 yuan / square meter.

[0109] The reference value for surrounding housing prices is: 11,000 yuan / square meter (the average housing price over several historical years).

[0110] The current population growth rate is: 2.5%.

[0111] The reference value of the population growth rate is: 2.0% (the average value of the population growth rate in several historical years).

[0112] The current economic growth rate is: 3.5%.

[0113] The reference value of economic growth rate is: 3.0% (the average GDP growth rate of several historical years).

[0114] The housing price coefficient of real estate to be registered is approximately: 0.31.

[0115] The population growth coefficient of real estate to be registered is approximately: 0.36.

[0116] The economic growth coefficient of real estate to be registered is approximately: 0.33.

[0117] Substituting the above data into the specific formula for calculating the regional market economic index of the real estate to be registered, we obtain: The regional market economic index of real estate to be registered = (0.31*(12000 / 11000)) + (0.36*(2.5% / 2.0%)) + (0.33*(3.5% / 3.0%)) = 1.18.

[0118] In this implementation plan, the regional market economic index takes into account the current market data (such as current housing prices, current annual population growth rate, current annual GDP growth rate) and historical reference values ​​when calculating, so that the index not only reflects the current situation of the market, but also takes into account the long-term market trend. The reference value obtained through historical mean analysis can balance short-term fluctuations and make the index more stable. The addition of current data improves timeliness, so that the index can quickly reflect the latest market conditions. This combination provides developers and investors with a comprehensive and reliable market economic reference, better supports real estate development and investment decisions, and through the standardized processing of housing prices, population growth rates and economic growth rates (i.e., de-unit processing), data of different dimensions can be compared and calculated on the same scale, effectively eliminating the impact of unit differences. This standardization method The standardization method ensures that the comprehensive analysis of housing prices, population growth and economic growth is more scientific and fair, making the market economic potential of different real estate more comparable. The standardized regional market economic index not only accurately reflects the relative weights of economic indicators, but also improves the comparability of the index across regions and projects, providing developers and investors with a more objective basis for judgment. By using historical housing price averages, historical population growth rates and historical economic growth rates as reference values, and conducting ratio analysis with current data, the relative competitiveness of real estate to be registered in the market can be more scientifically reflected. The addition of historical averages reduces the impact of short-term abnormal fluctuations on the index, and the ratio analysis further quantifies the economic growth potential of real estate to be registered, so that the index can not only reflect the vitality of the current market, but also has strong stability and reference value.

[0119] See also Figure 3The embodiment of the present invention provides a technical solution: a business data integration system for real estate registration, comprising: a first data acquisition module, a real estate initial registration data table establishment module, a second data acquisition module, an index analysis module, a comprehensive analysis module, and a real estate comprehensive registration data table establishment module; the first data acquisition module is used to acquire identification information, property certificate information, land use information, and transaction record information of the real estate to be registered, and perform preprocessing; the real estate initial registration data table establishment module is used to establish the real estate initial registration data table based on the identification information, property certificate information, land use information, and transaction record information of the real estate to be registered after preprocessing; the second data acquisition module is used to acquire current status information of the real estate to be registered, and the current status information includes terrain status data, land area development status data, environmental status data, infrastructure convenience data, and regional market economy data; The index analysis module is used to conduct a comprehensive analysis on the current status information of the real estate to be registered, and obtain the terrain development index, land area development index, environmental quality index, infrastructure convenience index, and regional market economy index of the real estate to be registered; the comprehensive analysis module is used to conduct a comprehensive analysis on the terrain development index, land area development index, environmental quality index, infrastructure convenience index, and regional market economy index of the real estate to be registered, and obtain the comprehensive development index of the real estate to be registered, and divide the development score grade of the real estate to be registered based on the preset development score grade rules; the real estate comprehensive registration data table establishment module is used to integrate the terrain development index, land area development index, environmental quality index, infrastructure convenience index, regional market economy index, comprehensive development index, and development score grade of the real estate to be registered into the real estate initial registration data table, obtain the real estate comprehensive registration data table, and store it.

[0120] In summary, this application has at least the following effects: By calculating multiple indicators such as terrain development index, land area development index, environmental quality index, infrastructure convenience index and regional market economy index, a comprehensive development index was constructed to systematically quantify the development potential of real estate. Unlike the previous reliance on manual evaluation or subjective judgment, quantitative indicators can more objectively and fairly reflect the comprehensive value and development potential of real estate. The development rating levels are divided based on these quantitative indicators, which not only facilitates the comparison of the development value of different real estate, but also provides developers and investors with a scientific decision-making basis, which helps to improve the rational use of real estate and the efficiency of resource allocation.

[0121] On the basis of the initial real estate registration data table, by integrating multi-dimensional indexes such as terrain, area, environment, infrastructure, and market economy, a comprehensive real estate registration data table is finally formed, which greatly improves the management efficiency and practicality of the data. The various indexes and development rating levels are integrated and stored together, which not only facilitates subsequent query and analysis, but also provides more systematic and reliable data support for government departments, developers and investors. At the same time, based on the preset development rating level rules, the development level of real estate can be quickly determined to achieve refined management of real estate.

[0122] By introducing multi-dimensional data such as topography, environment, infrastructure and regional economy, the registration information becomes more comprehensive and detailed. By acquiring and integrating the analysis of terrain status data, land area development status data, environmental status data, infrastructure convenience data and regional market economic data, the value of real estate can be evaluated from multiple angles, providing more valuable reference information for development and investment decisions, and effectively making up for the limitations of traditional real estate registration information.

[0123] The modular design structure not only reduces the coupling between the functional modules within the system, making it easier to maintain and update, but also allows the system to flexibly expand and optimize its functions. For example, if new data types need to be introduced in the future, it is only necessary to add corresponding data acquisition modules and analysis modules to the system to expand the existing analysis functions without rebuilding the entire system architecture. This flexibility significantly improves the adaptability of the system, allowing it to be continuously optimized with changes in policies, technologies and data sources, providing good technical support for the continuous improvement of real estate registration business.
