Automatic Allocation Method and System for Real Estate Map Elements Based on EPS Platform

Abstract

This invention relates to an automatic allocation method and system for real estate surveying and mapping elements based on the EPS platform. After defining the attributes of private and common elements and automatically creating real estate units, the method automatically encodes the defined private and common elements according to pre-defined element coding rules. In the subsequent area allocation calculation stage, based on the business rules for first- and second-level allocation of shared building area, the method automatically completes the area allocation calculation for common elements by parsing entity codes, thereby automatically customizing the allocation destination. This ultimately achieves the area allocation calculation for common elements of real estate, effectively reducing the error rate of manually specifying the allocation destination, optimizing the workflow, and saving work time. Furthermore, the obtained real estate surveying and mapping data results can be used to generate realistic 3D building layered and unit-specific data through data extraction and reconstruction techniques, which can then be applied to realistic 3D construction.

Description

Technical Field

[0001] This invention belongs to the field of real estate surveying and mapping technology, specifically relating to an automatic allocation method and system for real estate surveying and mapping elements based on the EPS platform. Background Technology

[0002] With the continuous acceleration of urbanization in Zhuhai and the increasing awareness of citizens' property rights, real estate property rights are receiving more and more attention from society. As a result, the volume of real estate property rights confirmation business is increasing, and the efficiency requirements for real estate surveying are also getting higher and higher. There are three main factors affecting the efficiency of real estate area measurement operations: first, the drawing of map element area blocks; second, the definition of map element attributes; and third, the determination of the allocation of shared area map elements.

[0003] However, the applicant found that the current common practice is for operators to draw area blocks of graphic elements, define all graphic element attributes, and then assign the allocation destination to each of the defined common area graphic elements one by one, and finally calculate the allocation of real estate area. This method is not only prone to omissions or errors in the allocation assignment of common area graphic elements when there are many common area graphic elements, but it is also inefficient.

[0004] Furthermore, the Ministry of Natural Resources is currently actively promoting the construction of real-scene 3D mapping. Real-scene 3D mapping is an important component of the national new infrastructure construction, providing a unified spatial foundation for economic and social development and the informatization of various departments. Its products are divided into terrain-level, city-level, and component-level, with component-level real-scene 3D mapping originating from commercial and professional surveying and mapping results. How to enhance the application prospects of real estate thematic business surveying and mapping results, beyond just real estate registration and confirmation of rights, and through on-demand assembly of professional surveying and mapping data, enable real estate thematic business surveying and mapping results to serve the needs of natural resource management and various industries, thereby precisely serving ecological civilization construction and economic and social development, is a new trend in breaking down industry barriers and improving data sharing services. In view of the above, this paper proposes a new technical route and processing method to solve the aforementioned problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an automatic allocation method for real estate mapping elements based on the EPS platform, and a system for the automatic allocation method for real estate mapping elements based on the EPS platform.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides an automatic allocation method for real estate mapping elements based on the EPS platform, comprising:

[0008] S1. Define private property elements: First, define the floors within the real estate, including standard floors, ground floors, roof floors, etc. Then, define the attributes of all private property elements within the real estate, including the name, function, ownership type, number of floors, room number, unit number, structure type, and unit number within the floor of the private property elements. Configure dictionary tables for fields such as function, structure type, and ownership type of private property elements.

[0009] S2. Define common items: After completing the definition of all private items, define the attributes of common items, including common item name, function, weight attribute, attribute category, structure type, and household number within the layer, and configure dictionary tables for fields such as function, structure type, common attribute category, and weight attribute of common items.

[0010] S3. Create Real Estate Units: Based on the attributes defined in the graphic element, automatically create real estate units for the graphic elements whose unit number field has been assigned a value within the layer. The real estate units created at this time include privately owned graphic elements and shared ownership graphic elements that do not need to be allocated as independent units.

[0011] S4. Element Entity Coding: According to the pre-defined element coding rules, the predefined private and public elements are automatically and uniformly coded, and each element is assigned a real estate element entity code.

[0012] S5. Customized Element Allocation: In the allocation calculation stage, first-level allocation is performed: based on the entity code of the elements, all external half-wall elements with the same shared attribute code are parsed out, and the area of ​​the external half-wall elements is allocated to other elements in the same building. The area allocated to other elements is distributed according to the area ratio of each element. Then, second-level allocation is performed: the area of ​​shared elements whose unit number field within the floor is not assigned is allocated to the real estate unit created in S3. The allocation destination is determined by the functional area code, that is, the area of ​​the shared elements whose unit number field within the floor is not assigned plus the area obtained from the first-level allocation is allocated to the real estate unit with the same functional area code. The area ratio rules for the second-level allocation are the same as those for the first-level allocation.

[0013] Furthermore, the "automatic unified encoding of the defined private and common elements, and assignment of real estate element entity code to each element" mentioned in S4 specifically means that, according to the element encoding rules, each element is numbered sequentially according to natural building, logical building, above-ground or underground, unit number, floor number, common / private, functional classification, structural type, and sequence code to generate an entity code.

[0014] Furthermore, the entity code consists of 39 bits, and the primitive encoding rules are as follows:

[0015]

[0016] The automatic allocation method for real estate surveying elements based on the EPS platform described in this invention has two main aspects. First, during the stage where workers define the attributes of the drawn elements, the defined real estate surveying elements are automatically encoded using pre-defined element encoding rules. During the area allocation calculation stage, the area of ​​common building elements is automatically allocated according to the business rules for primary and secondary allocation of shared building area by parsing entity codes. This effectively reduces the error rate of manually specifying the allocation destination of elements and completes the process in one step during element definition, optimizing the workflow and saving time. Second, the real estate surveying data obtained through this method contains entity encoding information, which facilitates the generation of realistic 3D building floor and unit data through data extraction and reconstruction techniques, and can be applied to realistic 3D construction.

[0017] Secondly, the present invention also provides an automatic allocation system for real estate mapping elements based on the EPS platform, characterized in that it includes:

[0018] The private property element definition module is used to define the floors within a real estate, including standard floors, ground floors, roof floors, etc. Then, it defines the attributes of all private property elements within the real estate, including the name, function, ownership type, number of floors, room number, unit number, structural type, and unit number within the floor. It also configures dictionary tables for fields such as function, structural type, and ownership type of private property elements.

[0019] The common item element definition module is used to define the attributes of common item elements after all private item elements have been defined. These attributes include common item name, function, weight attribute, attribute category, structure type, and household number within the layer. The module also configures dictionary tables for fields such as function, structure type, common attribute category, and weight attribute of common item elements.

[0020] The Real Estate Unit Creation Module is used to automatically create real estate units based on the attributes defined for private and common property elements. The created real estate units include private property elements and common property elements that do not need to be allocated as independent units.

[0021] The primitive entity encoding module is used to automatically encode the defined private and public primitives according to the predefined primitive encoding rules, and assign a real estate primitive entity code to each primitive.

[0022] And a custom module for allocating the area of ​​graphic elements, which is used to automatically complete the area allocation of common graphic elements in the allocation calculation stage by parsing the entity codes of private and common graphic elements and in accordance with the business rules for the first and second levels of allocation of common building area.

[0023] For the various aspects of the second aspect mentioned above and the technical effects that each aspect may achieve, please refer to the above description of the technical effects that can be achieved for the first aspect or the various possible solutions in the first aspect, which will not be repeated here.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] like Figure 1 As shown, the automatic allocation method for real estate mapping elements based on the EPS platform described in this invention includes:

[0033] Step S1. Define private property elements: First, define the floors within the property, including standard floors, ground floors, roof floors, etc. Then, define the attributes of all private property elements within the property, including the name, function, ownership type, number of floors, room number, unit number, structural type, and unit number within the floor. Configure a dictionary table for the fields of function, structural type, ownership type, etc. of private property elements (only optional to be filled in by the operator to standardize the operation data).

[0034] Step S2. Define common item elements: After completing the definition of all private item elements, define the attributes of common item elements, including common item name, function, weight attribute, attribute category, structure type, and household number within the layer. Configure a dictionary table for the fields of common item element function, structure type, common attribute category, weight attribute, etc. (can only be filled in by the operator to unify the standard of operation data).

[0035] Step S3. Create Real Estate Units: Based on the attributes defined for private and shared property elements, automatically create real estate units for elements with assigned unit number fields within the floor (automatic allocation within functional areas is possible). The real estate units created at this time include private property elements (such as residential units, shops, etc.) and shared property elements that do not need to be allocated as independent units (such as shared ownership of elevated floors, property management rooms, etc.). If special situations occur during the creation process, such as adjacent balconies of units within the unit and adjacent units, and cannot be automatically determined, the operator must manually specify them.

[0036] Step S4. Entity Coding of Graphic Elements: According to the pre-defined graphic element coding rules, the predefined private and common graphic elements are automatically and uniformly coded. Each graphic element is assigned a real estate graphic element entity code. Specifically, according to the graphic element coding rules, each graphic element is numbered sequentially according to natural building, logical building, above-ground / underground, unit number, floor number, common / private, functional classification, structural type, and sequence code to generate an entity code.

[0037] In one possible implementation, the entity code consists of 39 bits, and the primitive encoding rules are shown in Table 1 below:

[0038] Table 1

[0039]

[0040] Step S5. Customized Element Allocation: In the allocation calculation stage, firstly, primary allocation is performed: based on the entity code of the elements, all external half-wall elements with the same shared attribute code are parsed out (i.e., all external half-wall elements are parsed out based on the defined shared attribute code of the external half-wall elements, for example, all external half-wall elements with shared attribute code 0201 in Table 4 below are parsed out), and the area of ​​the external half-wall elements is allocated to other elements in the same building. The area allocated to other elements is distributed according to the area ratio of each element. Then, secondary allocation is performed: the area of ​​shared elements whose unit number field within the floor is not assigned is allocated to the real estate unit created in S3. The allocation destination is determined by the functional area code, that is, the area of ​​the shared elements whose unit number field within the floor is not assigned is added to the area obtained from the primary allocation and allocated to the real estate unit with the same functional area code. The area ratio rules for secondary allocation are the same as those for primary allocation.

[0041] The method described in this invention offers two advantages. First, it enables automatic encoding of defined real estate surveying elements during the element drawing and attribute definition stage by operators, using pre-defined element encoding rules. Second, it facilitates automatic allocation of common area elements during the area allocation calculation stage through code parsing. This not only improves the automation level of surveying production but also effectively reduces the error rate of manually specifying element allocation destinations. Furthermore, this process is completed in one step during element definition, simplifying the workflow and improving efficiency. This is particularly beneficial for complex buildings with thousands of allocation elements, where the efficiency improvement is even more significant compared to existing methods. Second, the real estate testing data obtained through this method can be directly extracted and integrated according to requirements based on element entity encoding, and applied to real-world 3D construction. Specifically, in the completed real estate survey results, each area element has a 39-bit entity code. By parsing the code, the graphic elements and corresponding attributes of each building, such as the unit, floor, public ownership, private ownership, main structure, non-main structure, and usage function, can be directly extracted. Then, through reconstruction, fusion and other technologies, real-scene 3D building floor and unit data can be generated without the need for secondary processing of CAD floor and unit data, saving a lot of time and economic costs.

[0042] like Figure 2 As shown, the present invention also provides an automatic allocation system for real estate mapping elements based on the EPS platform, comprising:

[0043] The private property element definition module 100 is used to define the floors within the real estate, including standard floors, ground floors, roof floors, etc., and then define the attributes of all private property elements within the real estate, including the name, function, ownership type, number of floors, room number, unit number, structure type, and unit number within the floor of the private property element, and configure dictionary tables for fields such as function, structure type, and ownership type of private property elements;

[0044] The common item element definition module 200 is used to define the attributes of common item elements after all private item elements have been defined. These attributes include common item name, function, weight attribute quality, attribute category, structure type, and household number within the layer. The module also configures a dictionary table for the fields of common item element function, structure type, common attribute category, and weight attribute quality.

[0045] The Real Estate Unit Creation Module 300 is used to automatically create real estate units based on the attributes defined by private and common elements, for elements whose unit number field has been assigned a value within the layer.

[0046] The graphic element entity coding module 400 is used to automatically encode the defined private and common graphic elements according to the pre-defined graphic element coding rules, and assign a real estate graphic element entity code to each graphic element. Specifically, according to the graphic element coding rules, each graphic element is numbered sequentially according to natural building, logical building, above-ground or underground, unit number, floor number, common / private, functional classification, structural type and sequence code to generate an entity code.

[0047] And a custom module 500 for allocating the area of ​​shared building elements, which is used to automatically allocate the area of ​​shared building elements by parsing the entity codes of private and shared building elements during the area allocation calculation stage, according to the business rules of first-level and second-level allocation of shared building area.

[0048] The following examples further illustrate the automatic allocation method and system for real estate mapping elements based on the EPS platform described in this invention.

[0051] 1. Definition of Private Property Elements. First, define the floors within the building, such as standard floors, ground floors, and rooftop floors. Then, define the attributes of all private property elements (non-common area elements), including the element's name, function, ownership type, room number, unit number, structural type, and unit number within the floor. Specifically... Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 This defines the attributes of the interior elements and balcony of apartment 04 on the 25th floor of the standard floor.

[0052] 2. Definition of Common Property Elements. After defining all private property elements, define the attributes of common property elements, including common property element name, usage function, ownership nature, attribute category, structure type, and unit number within the floor, etc., as detailed below. Figure 6 As shown.

[0053] 3. Create real estate unit households. Based on the defined attributes, the system automatically creates households, clarifying the relationships between the elements that make up each household, specifically as follows: Figure 7 As shown, Figure 7 Unit 04 includes three balcony elements and one interior element.

[0054] 4. Element Entity Coding. According to the pre-compiled coding rules (refer to the element coding rule table above), assign a real estate element entity code to each element. For example, the generated entity code is 39 bits long. An example of the entity code is shown below; see details below. Figure 8 ;
