Description

Technical Field

[0001] This invention relates to the field of urban construction informatization, and in particular to a planning decision-making CIM system and planning decision-making method that supports dynamic model generation. Background Technology

[0002] In fields such as urban planning and industrial park construction, the scientific nature and efficiency of planning decisions directly impact project implementation outcomes, while accurate estimation of development costs is the core basis for investment decisions. Traditional planning work largely relies on two-dimensional drawings and manual adjustment of indicators, resulting in problems such as low model visualization, lag in the linkage between indicator adjustments and models, and cumbersome operational procedures. Furthermore, development cost estimation requires separate cost estimation software and manual extraction of relevant data from the planning scheme for input into the cost system, leading to data transmission delays, large errors, and a lack of dynamic linkage with the planning scheme, making it difficult to simultaneously verify the feasibility of the planning scheme and the rationality of investment.

[0003] While existing CIM (City Information Modeling) planning platforms possess certain model generation and visualization capabilities, most suffer from fragmented component functions, poor operational interactivity, and a lack of deep integration between planning models and cost estimation. Some platforms require inputting indicators via an external keyboard and then navigating using a mouse, resulting in cumbersome device connections. Other platforms lack the ability to quickly switch model states and conveniently access indicator adjustment interfaces, leading to low planning operation efficiency. More importantly, existing platforms cannot automatically complete development cost estimation based on dynamically adjusted planning models, requiring separate calculations using external tools. This severs the connection between planning design and investment decisions, making it difficult to meet the needs of integrated decision-making. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned background technology and provide a planning decision CIM system and planning decision method that supports dynamic model generation, which has the characteristics of high integration, convenient operation, real-time linkage between indicator input and model dynamic adjustment, and development cost linkage estimation function, so as to solve the shortcomings of the existing technology.

[0005] The present invention provides a planning decision CIM system that supports dynamic model generation, including a display, an operation panel, a core data processing module and a CIM database. The signal input terminal and signal output terminal of the core data processing module are respectively connected to the operation panel and the display, and the communication terminal of the core data processing module is connected to the CIM database.

[0006] In the above technical solution, the core data processing module generates a planning model and estimates costs through data interaction and computation.

[0007] In the above technical solution, the core data processing module, based on the input instructions transmitted by the operation board, calls the planning basic data, indicator constraints and planning model algorithms in the CIM database to perform calculations, generate or adjust the planning model, and the CIM database saves the generated or adjusted planning basic data, indicator constraints and planning model algorithms as detailed planning model data.

[0008] In the above technical solution, the core data processing module, based on the detailed planning model data and the pre-stored cost data in the CIM database, performs matching calculations on the detailed planning model data and the pre-stored cost data in the CIM database to complete the development cost estimation.

[0009] In the above technical solution, the core data processing module controls the display to receive transmission signals and display the planning model, update the planning model form in real time, provide feedback on the operation status, and display the development cost estimation results; the core data processing module controls the development cost estimation results to be updated synchronously with the adjustment of planning indicators and displayed visually.

[0010] In the above technical solution, the operation panel includes a control unit and an indicator input button group connected to the signal terminal of the control unit. The control unit is connected to the signal terminal of the core data processing module through a data transmission interface and a data cable. The indicator input button group is equipped with numeric and percentage input buttons, which can input plot ratio, building density, green space ratio, building height, number of building floors, and the proportion of residential, commercial, and industrial functional spaces.

[0011] In the above technical solution, the operation panel is equipped with a control joystick connected to the signal terminal of the control unit. The control joystick adopts a game controller-style control logic to realize the movement, rotation and scaling of the virtual space roaming perspective.

[0012] In the above technical solution, the operation panel is provided with a function switching button group connected to the signal terminal of the control unit. The function switching button group includes a two-dimensional / three-dimensional switching button, an information display button, and an indicator interface switching button. The two-dimensional / three-dimensional switching button is used to control the switching of the planning model display screen on the display between two-dimensional and three-dimensional states. The information display button is used to control the presentation and disappearance of information related to the planning model and cost estimation results. The indicator interface switching button is used to switch to the indicator data adjustment interface, and continuous clicking can switch to the next indicator command in sequence.

[0013] This invention also provides a planning decision-making method supporting dynamic model generation, comprising the following steps: S1, the indicator input button group transmits the input target planning indicators to the operation panel, or the joystick is used to activate the virtual space roaming mode, and the operation signal is transmitted to the core data processing module via the data transmission interface and data cable; S2, upon receiving the signal, the core data processing module calls the planning basic data and planning model algorithm in the CIM database to perform calculations and generate the corresponding two-dimensional or three-dimensional planning model; S3, the core data processing module extracts detailed data on component type, quantity, size, and material from the planning model, calls the pre-loaded cost basic data in the CIM database, and completes the overall development through the cost accounting algorithm. Cost and itemized cost estimation generates a cost estimation report containing detailed component costs, detailed labor costs, and total investment estimates. The S4 core data processing module transmits planning model data, control signals, and cost estimation data to the display. Upon receiving the signal, the display presents the corresponding planning model and cost estimation report in real time. If planning indicators are adjusted via the control panel, the core data processing module repeats the above calculation process, synchronously updating the planning model and cost estimation results. Information display / hide keys control the display and hiding of planning model information and development cost estimation results. Two-dimensional / three-dimensional switching allows for switching between two-dimensional and three-dimensional states of the planning model. Indicator interface switching keys allow switching between various indicator adjustment interfaces.

[0014] The above technical solution also includes step S0: the operation board is connected to the data transmission interface via a data cable to realize communication between the operation board and the core data processing module; the display is connected to the core data processing module via a wired line; the core data processing module establishes communication with the CIM database in advance to complete the preloading of planning basic data, indicator constraints, planning model algorithms and cost basic data.

The operation signal is transmitted to the core data processing module 8 through the data transmission interface 6 and the data cable 7. S2. After receiving the signal, the core data processing module 8 first calls the planning basic data and planning model algorithm in the CIM database 9 to perform calculations and generate the corresponding two-dimensional or three-dimensional planning model. S3, the core data processing module 8 then extracts detailed data such as component type (e.g., concrete components, steel structure components), quantity, size, and material from the planning model, calls the pre-loaded cost basis data in the CIM database 9, and completes the estimation of total development cost and itemized cost through cost accounting algorithm, generating a cost estimation report containing component cost details, labor cost details, total investment estimate, etc. S4. The core data processing module 8 then transmits the planning model data, control signals, and cost estimation data to the display 1. After receiving the signals, the display 1 displays the corresponding planning model and cost estimation report in real time. If the operator adjusts the planning indicators through the operation panel 2, the core data processing module 8 will repeat the above calculation process and update the planning model form and development cost estimation results synchronously.
