[0036] See also Figure 1 As shown, an indoor space system based on data analysis includes an indoor space acquisition module, a space analysis module, a data analysis module and an optimization execution module;

[0037] See also Figure 2 , 3 As shown, the indoor space acquisition module is used to obtain indoor space data, including space structure data, indoor items and furniture data, space usage behavior data, space perception data and user input data; and obtain the main source of environment and usage data through various sensors installed indoors (light, temperature and humidity, infrared, noise, etc.); then use laser scanning technology (such as LIDAR) to obtain high-precision indoor space three-dimensional data, accurately measure room dimensions, furniture positions, etc.; through Building Information Modeling (BIM), obtain accurate space structure information such as building design drawings, equipment layout, material usage, etc.; it should be noted that user input data is through mobile applications or system interfaces, and users can manually input their needs, preferences and feedback on the use of space;

[0038] The spatial analysis module analyzes the spatial structure data and the indoor objects and furniture data, specifically:

[0039] Through measuring tools such as laser radar (LIDAR), infrared sensors, and rangefinders, the geometric dimensions (such as length, width, and height) and 3D model data of the room, including the specific dimensions of the walls, floors, and ceilings, are collected; the indoor 3D model is constructed based on the 3D model data, and the architectural design drawings of the room are imported, including detailed information such as the location of doors and windows, structural support points, and load-bearing walls;

[0040] Based on the constructed indoor 3D model, the indoor 3D model is divided into corresponding demand areas according to user needs, and the corresponding demand areas are displayed in the indoor 3D model; then the flatness of the indoor walls, floors and ceilings in the indoor 3D model is measured, specifically: a number of position points are constructed on the indoor walls, floors or ceilings of the demand areas corresponding to the indoor 3D model, and each point is connected with the surrounding adjacent position points to obtain a grid structure; then the distance between each position point in the grid model and the surrounding adjacent position points is calculated, and a fixed point is selected in the point set model as the XYZ coordinate system, and then the formula is used: Output the distance d between position point i and the surrounding adjacent position point j ij , and (x i ,y i , z i ) and (x j ,y j , z j ) are the three-dimensional coordinates of the position point i and the surrounding adjacent position points j, i = 1, 2, 3, ..., n, j = 1, 2, 3, ..., n; then the sum of the distances d between the position point and the surrounding adjacent position points is calculated by the formula Output the sum dz of the position point and its neighboring position points, where N is the total number of the position points neighboring the position point, L = 1, 2, 3, ..., N; obtain the sum dz of each position point and its neighboring position points and the total mean dJ of each position point and its neighboring position points in the grid structure, and then compare dz with dJ. If dz is greater than dJ, the corresponding position point will be marked; otherwise, it will not be marked;

[0041] Next, the marked position points are analyzed to obtain the marked contour, and the marked contour features are analyzed. According to the design drawings of the room, the area, length, width, height of the corresponding wall, floor and ceiling in the room and the proportion of the marked contour in the indoor three-dimensional model are obtained to obtain the size of the marked contour; the marked contour features and the corresponding size are compared with the standard furniture model library. If the overlap rate of the compared contour features reaches 90% and the corresponding size matching rate reaches 95%, it is determined that the contour feature is the model corresponding to the standard furniture model library, and the specific furniture in the room (such as tables, sofas, cabinets, etc.) is determined;

[0042] The data analysis module is used to analyze the indoor space layout, specifically:

[0043] Based on the collected accurate spatial structure information such as architectural design drawings, equipment layout, material usage, etc., the drawings provide accurate information about the building framework such as walls, doors and windows, structural columns, beams, etc., and divide the indoor functional areas (before dividing the space, the system needs to understand the owner's intention for the use of the space, such as whether certain areas are used as public spaces, whether certain rooms have special functional requirements, etc.);

[0044] By making a preliminary functional area division: By analyzing the design drawings, the main structures and boundaries of the room are identified, including physical boundaries such as walls, columns, doors, windows, etc. It is also necessary to mark the boundaries of the traffic flow lines (traffic routes) and mark these structures as the preliminary dividing lines of the functional areas; it should be noted that on the design drawings: such as corridors, doorways, etc., these are the key parts of the indoor traffic flow lines and cannot be blocked by furniture or other functional areas; such as the paths connecting the functional areas inside the room, ensure that people can move easily in the space; for example, the traffic line between the kitchen and the dining room should be short and smooth, and the passage between the bedroom and the bathroom should be convenient and hidden;

[0045] Analyze the impact of equipment layout on functional areas; for example, the location of air-conditioning outlets, drainage pipes, and power sockets will affect the layout of furniture, which in turn affects the division of functional areas; for example, the kitchen area needs to be divided based on the location of water pipes and exhaust systems; specifically, analyze:

[0046] By obtaining the score of each equipment factor (L, V, P, N); L is the lighting impact score, by the formula: Among them, I l is the ideal lighting intensity required for the area, I s is the actual collected illumination intensity, D L is the distance factor of the equipment layout on the lighting. The closer the distance, the higher the score. The score decreases when the distance is farther or unevenly distributed. V is the ventilation impact score, which is given by the formula: Among them, V l is the ideal ventilation volume required for the area, V s is the actual collected ventilation volume, D V It is the distance factor of equipment layout on ventilation, reflecting the distance between ventilation equipment and target area; P is obtained by analogy, where P is the power supply impact score; N is the noise interference impact score, which is calculated by the formula: V = N s ×D V , where N s is the actual noise level generated (the greater the noise, the lower the impact score), D N It is the distance factor between the device and the noise source. The farther the distance is, the higher the score is. The impact increases when the device is close to the functional area.

[0047] Then, the score of each equipment factor (L, V, P, N) is calculated comprehensively, and the overall influence coefficient SYZ of the equipment layout functional area is output through the formula: SYZ = L×L'+V×V'+P×P'+N×N', where L', V', P', and N' are weight coefficients of different equipment factors respectively (the weights can be set according to demand or actual design requirements); SYZ is compared with the influence interval of the equipment layout on the functional area. If SYZ belongs to the influence interval of the corresponding equipment layout functional area, it is a normal layout; if SYZ does not belong to the influence interval of the corresponding equipment layout functional area, and is less than the influence interval of the corresponding equipment layout functional area, it is an excellent layout; if SYZ does not belong to the influence interval of the corresponding equipment layout functional area, and is greater than the influence interval of the corresponding equipment layout functional area, it is a poor layout;

[0048] Then, make a preliminary division by identifying the room functions (such as bedroom, kitchen, living room, etc.); the preliminary division of functional areas is consistent with the purpose of the room design; according to the design of traffic flow lines such as doors and corridors, divide the main channel area and the secondary channel area, and ensure the smooth and reasonable traffic in the space. On this basis, make a preliminary division confirmation analysis:

[0049] Analysis of noise and sound insulation effect: The impact of noise on the bedroom mainly comes from the external environment and internal equipment, so it is necessary to calculate the noise and sound insulation effect. The noise level is calculated by the formula: Output the total noise level inside the bedroom ZYZ, where Z1 is the noise level of the external noise source (for example, traffic noise, construction, etc.); Z2 is the noise inside the bedroom (for example, the noise generated by air conditioners, televisions, etc.), and Z i is the noise of the ith device or environmental source, n is the number of noise sources; X is the impact value of the room sound insulation effect, Among them, A j is the area of ​​the jth material (such as carpets, curtains, etc.), α jis the sound absorption coefficient of the jth material (such as the sound absorption coefficient of carpet is usually higher), RF is the room sound insulation performance coefficient (specifically, by placing a sound pressure meter outside the room, recording the sound pressure level F1 on one side of the sound source, and then placing another sound pressure meter at the corresponding position in the room, recording the sound pressure level F2 after passing through the room enclosure structure, and outputting the preliminary room sound insulation coefficient R through the formula: R=F1-F2, and then collecting and calculating the preliminary room sound insulation coefficient R at different positions inside and outside the room, obtaining multiple preliminary room sound insulation coefficients R, calculating the average sound insulation coefficient, and using the average sound insulation coefficient as the room sound insulation performance coefficient RF); comparing the obtained total noise level ZYZ inside the bedroom with the preset ideal noise level thresholds LYZ1 and LYZ2 (LYZ1<LYZ2) of the bedroom, if ZYZ>LYZ1, the bedroom noise level is judged to be in an excellent state; if ZYZ≥LYZ1, ZYZ≤LYZ2, the bedroom noise level is judged to be in an ideal state; if ZYZ<LYZ2, the bedroom noise level is judged to be in a poor state;

[0050] For light brightness analysis, by calculating the light intensity, the formula

[0051] Output light intensity GQZ, Cm is the window area, GQ is the light intensity outside the window, Cf is the room area, Tg is the light transmittance of the window, RZ is the reflection coefficient of the wall and ceiling in the room; and by considering the influence of the incident angle of the light, the actual available light brightness B in the room is output through the formula: B = GQZ × Gc × cos (θ), Gc is the light direction coefficient (positive for the sun and negative for the shade, the value range is usually 0 to 1), θ is the incident angle (degrees) of the light and the window surface;

[0052] Then the area is analyzed. After the area analysis, the area required for the basic functional area (such as the minimum requirements for bedrooms, kitchens, etc.), the number of bedrooms in the room, the expected number of people living in the room, and the additional area required according to other functional requirements (such as storage space, furniture arrangement, etc.) are determined; it should be noted that all of them are obtained by asking the user; and the area requirement value M is output through the formula: M=JM+(Rs×Rm)+Mq, where JM is the area value required for the basic functional area, Rs is the expected number of people living in the room, Rm is the number of bedrooms in the room, and Mq is the additional area value required for other functional requirements;

[0053] Then all factors are calculated comprehensively to get the preliminary division confirmation value of the room, specifically through:

[0054] CBQZ=ZYZ×a1+X×a2+GQZ×a3+B×a4+M×a5 outputs the preliminary classification confirmation value CBQZ, where a1, a2, a3, a4 and a5 are weight coefficients of corresponding factors, which are set according to actual usage requirements and comfort, and the sum is 1;

[0055] The optimization execution module obtains the step division confirmation value CBQZ and the overall influence coefficient SYZ of the equipment layout functional area for combined analysis, and generates a variety of overall influence coefficient combination optimization schemes, specifically:

[0056] According to the calculation results of CBQZ and SYZ, the current status of each area in terms of functional division and equipment layout is first determined; the two indicators are linearly combined to generate an optimization objective function YHS, YHZ = σ × CBQZ + τ × SYZ, σ and τ are weight coefficients, which are used to express the preference for the rationality of functional areas and the impact of equipment layout; in order to optimize the design of functional areas and equipment layout, different optimization schemes can be generated based on different combination strategies: the proportion of σ and τ is changed to generate different optimization schemes; for example, the weight of σ can be increased to prioritize the rationality of functional division, or the weight of τ can be increased to prioritize the impact of equipment layout; and the advantages and disadvantages of different optimization schemes are displayed for users to choose; for example: a certain scheme focuses on the reasonable division of functional areas, especially in terms of room use, light, noise, etc., to ensure that the functionality and living comfort of each room reach a high level. Advantages: the spatial layout is more in line with living or use needs; the living comfort is high, especially factors such as noise and lighting are optimized; Disadvantages: the energy efficiency optimization of equipment layout is weak, which may lead to higher energy consumption; the location of equipment may affect the convenience and efficiency of space.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
