Description

Technical Field

[0001] The present invention relates to the technical field of building environment analysis and management, and in particular to an urban building space operation and maintenance management method based on GIS+BIM+LOT. Background Art

[0002] BIM (Building Information Modeling) is a building or construction information model that is composed of sufficient information to support new product development management and can be directly interpreted by computer applications, that is, the life cycle management of the building environment supported by digital technology. The core of the BIM model is to establish a virtual three-dimensional model of the building project and use digital technology to provide this model with a complete and actual building project information library.

[0003] As a spatial decision support system, GIS (Geographic Information System or Geo-Information system) models are increasingly dependent on the analysis and simulation capabilities of applied models. GIS models are concise images that describe the various elements of the system with certain expression rules through appropriate screening. They are simplified expressions of the real world. Models usually express the development process or results of a system.

[0004] The Internet of Things (IoT) technology connects objects to the network through information sensing devices to achieve intelligent identification, positioning, tracking, supervision and other functions. It covers key technologies such as sensors, RFID, embedded systems, and is widely used in intelligent operation and maintenance, smart transportation, and medical fields.

[0005] Urban buildings, as an important symbol of urban development, not only carry the living and working needs of residents, but also reflect the cultural heritage and modernization level of a city. Among many urban buildings, office buildings are the core places for commercial activities. The efficiency and quality of their daily operation and maintenance are directly related to the operating efficiency of enterprises and the working environment of employees. In the daily operation and maintenance process of office buildings, manual inspection is an important means to ensure the safe and efficient operation of buildings. Its necessity is mainly reflected in the following aspects: 1) Manual inspection can intuitively observe the operating status of facilities inside and outside the building, timely discover and deal with equipment failures or safety hazards, and prevent accidents. 2) Through regular inspections, potential problems can be discovered and dealt with in a timely manner, reducing downtime caused by equipment failures and improving operation and maintenance efficiency. 3) As a crowded place, office buildings are of vital importance for safety. Manual inspections can promptly discover and deal with problems that affect personnel safety, such as blocked fire passages and aging electrical equipment.

[0006] Although manual inspections play an important role in the daily operation and maintenance of office buildings, there are also some problems that cannot be ignored. In multi-story or large office buildings, it is difficult for operation and maintenance managers to accurately know the location of inspectors, which not only affects the accuracy and consistency of inspection data, but may also lead to omissions or duplications in inspection work. In addition, since it is impossible to obtain the exact location of inspectors, it is difficult for operation and maintenance managers to determine or generate inspection routes for inspectors, resulting in an inability to effectively evaluate the degree of inspection completion by inspectors. Summary of the invention

[0007] In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide a method for urban building space operation and maintenance management based on GIS+BIM+LOT, which integrates the BIM model and GIS model of the target building to generate a three-dimensional visualization model of the building, thereby improving the visualization and intelligence level of building operation and maintenance management; at the same time, combining LOT technology to display the real-time location of inspection personnel in the three-dimensional visualization model of the building, thereby improving the efficiency and management effect of the inspection work.

The integration of the two can realize the comprehensive integration of information inside and outside the building, build a complete information system, and provide comprehensive data support for the operation and maintenance management of urban building space. Secondly, the three-dimensional visualization model of the building presents the building space in a three-dimensional form intuitively, so that the operation and maintenance management personnel can more intuitively understand the structure, layout and equipment of the building space, thereby improving the visualization of the operation and maintenance management and reducing the difficulty of management. Finally, by integrating the BIM and GIS models, the refined management of the building space can be realized. For example, the building equipment can be accurately located, monitored and maintained based on the three-dimensional visualization model of the building, and the efficiency and accuracy of the equipment operation and maintenance can be improved; at the same time, the integrated three-dimensional visualization model of the building can be used as one of the basic data of the digital twin city to provide support for the intelligent operation and maintenance management of the urban building space.

First, through the data association between the positioning base station and the simulation base station, the position information of the inspectors in the building space can be obtained in real time and displayed in the three-dimensional visualization model of the building, which helps the operation and maintenance management personnel to grasp the dynamic situation of the inspectors in real time and ensure the smooth progress of the inspection work.

Finally, by recording and analyzing the patrol personnel's movement trajectory, residence time and other data, the patrol personnel's inspection work can be quantitatively evaluated and optimized. For example, the patrol route, frequency and time can be adjusted according to the patrol personnel's actual work situation and needs, so as to improve the pertinence and effectiveness of the patrol work.

[0058] The present invention integrates the BIM model (Building Information Modeling) and GIS model (Geographic Information System) of the target building to generate a three-dimensional visualization model of the building. First, the BIM model mainly focuses on the information integration and management inside the building, while the GIS model can integrate and manage a wide range of geographic spatial information. The integration of the two can realize the comprehensive integration of information inside and outside the building, build a complete information system, and provide comprehensive data support for the operation and maintenance management of urban building space. Secondly, the three-dimensional visualization model of the building presents the building space in a three-dimensional form intuitively, so that the operation and maintenance management personnel can more intuitively understand the structure, layout and equipment of the building space, thereby improving the visualization of the operation and maintenance management and reducing the difficulty of management. Finally, by integrating the BIM and GIS models, the refined management of the building space can be realized. For example, the building equipment can be accurately located, monitored and maintained based on the three-dimensional visualization model of the building, and the efficiency and accuracy of the equipment operation and maintenance can be improved; at the same time, the integrated three-dimensional visualization model of the building can be used as one of the basic data of the digital twin city to provide support for the intelligent operation and maintenance management of the urban building space.

[0059] The present invention obtains the position of the inspectors through a positioning base station and a positioning module based on the Internet of Things (LOT) technology, and then establishes a data association between the positioning base station and the simulation base station, so that the positioning signal generated by the positioning base station can be synchronized to the simulation base station, and the real-time position of the inspectors is displayed in the three-dimensional visualization model of the building. First, through the data association between the positioning base station and the simulation base station, the position information of the inspectors in the building space can be obtained in real time and displayed in the three-dimensional visualization model of the building, which helps the operation and maintenance management personnel to grasp the dynamic situation of the inspectors in real time and ensure the smooth progress of the inspection work.

At the same time, by recording and analyzing the patrol personnel's behavioral data, unsafe patrol behaviors can be discovered and corrected in a timely manner, thereby improving the management effect of the patrol work.

[0060] During the specific implementation process, the positioning of patrol personnel can be achieved through Internet of Things technologies such as RFID, Bluetooth and UWB.

[0061] Specific:

[0062] 1. The positioning base station is an RFID card reader, and the positioning module carried by the inspection personnel is an RFID tag;

[0063] When the inspector reaches the location of the RFID reader, the RFID tag he carries comes into contact with the RFID reader to generate a positioning signal.

[0064] 2. The positioning base station is a Bluetooth gateway, and the positioning module carried by the inspection personnel is a Bluetooth beacon;

[0067] When the patrol personnel enter the ultra-wideband communication range of the UWB positioning base station, the UWB tag card they carry conducts ultra-wideband communication with the UWB positioning base station to generate a positioning signal.

[0068] During the specific implementation process, the BIM basic data of the target building includes geometric information, non-geometric information and surrounding environment information;

[0069] Geometric information includes the overall shape, size, floor structure, geometric dimensions and positional relationships of components such as walls, doors, windows, stairs, etc. These data are usually obtained through on-site measurements, design drawings (such as floor plans, elevations, and sections), etc.

[0070] Non-geometric information includes building material information, such as concrete strength, steel bar specifications, door and window materials, etc. Building functional information, such as room usage (office, conference room, bathroom, etc.), equipment location (air conditioner, elevator, fire fighting equipment, etc.). Building performance information, such as thermal insulation performance, sound insulation performance, lighting performance, etc. These data are usually obtained through design drawings, equipment lists, product manuals, etc.

[0071] The surrounding environment information includes the terrain, landforms, roads, greenery, etc. around the building. These data can be obtained through GIS (Geographic Information System) technology.

[0072] Input the BIM basic data of the target building into the BIM software for modeling to obtain the building BIM model.

[0074] During the specific implementation process, the GIS basic data of the target building includes basic building data, building attribute data and surrounding environment data;

[0075] Building basic data includes plane data, height data and texture data. Plane data refers to the outline data of the building projected onto the ground plane in the top view, which can be obtained through 2D GIS extraction or automatic extraction from satellite images. Height data refers to the height information of the building, which can be directly extracted from the image, or obtained through LiDAR combined with aerial images. Texture data refers to the surface texture information of the building, which can be obtained by ground photography, computer simulation drawing or aerial photography.

[0076] Building attribute data includes the building's purpose, structure type, construction year, number of floors, floor area, building area and other attribute information. This information is usually obtained by consulting relevant documents or conducting on-site surveys.

[0077] Surrounding environment data includes geographical information such as topography, landforms, roads, green areas, water systems, etc. around buildings. These data can be obtained through GIS technology, such as using satellite remote sensing data and drone aerial images.

[0078] Input the GIS basic data of the target building into the GIS software for modeling to obtain the building GIS model.

[0079] BIM modeling software includes ArcGIS software, GeoScenePro software and QGIS software.

[0080] During the specific implementation process, the following steps are used to generate a 3D visualization model of the building:

[0081] S401: Acquire corresponding BIM model data and GIS model data from the building BIM model and the building GIS model;

[0082] In this embodiment, the BIM model data includes information such as the building's geometric shape, material properties, spatial relationships, etc. The GIS model data includes geographic information data of the target building and its surroundings, such as terrain, roads, vegetation, etc.

[0083] S402: Converting BIM model data and GIS model data into a unified data format;

[0084] In this embodiment, a data conversion tool or software is used to convert BIM and GIS data into a unified format.

[0085] S403: Convert the BIM model data and the GIS model data to the same spatial reference system;

[0086] S404: Load the BIM model data and the GIS model data into the GIS software, and use a data integration tool to merge the two into one data set;

[0087] S405: Using a 3D modeling tool in the GIS software to fuse the BIM model data and the GIS model data in the data set to generate a 3D building model;

[0088] S406: Add attributes to the building 3D model and render it through a 3D visualization tool to generate a 3D visualization model of the building.

[0089] In this embodiment, the attributes include the name, purpose, and construction year of the building.

[0090] During the specific implementation process, the simulated base station is generated through the following steps:

[0091] S501: Acquire location data of a positioning base station in a target building;

[0092] S502: Convert the location data into a format recognizable by GIS software of the building three-dimensional visualization model;

[0093] S503: In the three-dimensional visualization model of the building, locate the specific position of the base station in the target building according to the converted position data;

[0094] S504: Generate a simulated base station corresponding to the positioning base station at a corresponding position of the three-dimensional visualization model of the building.

[0095] In this embodiment, this can be achieved by inserting a pre-designed base station model or a custom base station model into the three-dimensional visualization model of the building.

[0096] During the specific implementation process, during the inspection period, the real-time positions of the inspectors displayed in the three-dimensional visualization model of the building are connected in chronological order to generate the actual inspection routes of the inspectors.

[0097] The present invention generates an actual inspection route of the inspectors based on the displayed real-time positions of the inspectors. First, by displaying the positions of the inspectors in real time and generating the actual inspection routes, the movement trajectory of the inspectors can be dynamically tracked to ensure the comprehensiveness and accuracy of the inspection work. Secondly, the actual inspection routes generated in real time make the inspection work more transparent, and the operation and maintenance management personnel can understand the inspection progress and positions of the inspectors at any time; when problems arise or the inspection situation needs to be traced back, the actual inspection routes can be used for backtracking. Finally, by analyzing the actual inspection routes, redundant paths or missed areas that may exist during the inspection process can be discovered, providing a basis for the subsequent optimization of the inspection routes, and the operation and maintenance management personnel can adjust the inspection plans and routes according to the actual inspection routes to improve the inspection efficiency.

[0098] During the specific implementation process, the actual inspection route of the inspectors will be compared with the set recommended inspection route to evaluate the degree of inspection completion of the inspectors.

[0099] In this embodiment, the degree of completion of the inspection by the inspectors can be evaluated by calculating the similarity between the actual inspection route and the recommended inspection route. For example, when the similarity is 80%, the degree of completion of the inspection by the inspectors is 80%. The calculation of the similarity of two paths can be achieved through existing mature methods such as broken line segment overlap calculation, dynamic time warping, and Hausdorff distance. Broken line segment overlap calculation: The route is regarded as consisting of a series of broken line segments; the length of the overlap of all broken line segments is calculated, and then divided by the total length to obtain the similarity. Dynamic Time Warping (DTW): Automatically warp two sequences and perform local scaling and alignment on the time axis to make their shapes as consistent as possible, thereby obtaining the maximum possible similarity. Hausdorff distance: A metric method for measuring the maximum and minimum distance between two sets, which can be used to calculate the shape difference between two trajectories.

[0100] The present invention compares the actual inspection route of the inspectors with the set recommended inspection route to evaluate the inspection completion degree of the inspectors. First, by comparing the actual inspection route with the recommended inspection route, it is possible to intuitively understand whether the inspectors have conducted inspections according to the recommended route, as well as the coverage and completion of the inspections. The comparative evaluation method can more accurately reflect the work quality and efficiency of the inspectors. Secondly, during the comparative evaluation process, if it is found that there is a large difference between the actual inspection route and the recommended inspection route, the reasons can be further analyzed, such as whether there is equipment failure, personnel negligence or unreasonable route setting, which helps the operation and maintenance management personnel to promptly discover and solve problems in the inspection process and improve the quality and efficiency of the inspection work. Finally, through multiple comparative evaluations, it is possible to find problems and deficiencies in the recommended inspection route, such as whether there are missing areas, whether it is too long or complicated, etc. The operation and maintenance management personnel can adjust and optimize the recommended inspection route according to the actual situation to make it more in line with the actual inspection needs.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
