Description

Technical Field

[0001] The present invention relates to the field of data interaction technology, and in particular to a real-time interaction method, device and equipment based on BIM data and Internet of Things data. Background Art

[0002] Building Information Modeling (BIM) data contains data on the space, geometry, attributes, and relationships of components, while IoT data contains a large amount of real-time sensing equipment and sensor status data. The BIM integrated application of monitoring equipment is a scenario-based expression of smart space. In the development of a centralized three-dimensional visualization management system for buildings, BIM data and IoT data are usually used. Through the three-dimensional visualization of the BIM model, the model file in the IFC (industry foundation classes) format is uploaded to the server. The server first parses the IFC file into triangular mesh data, and then links the device model data through a unified API interface to realize the three-dimensional visualization browsing of the building model under the web graphics library (WebGL), thereby achieving integrated interaction between the model data and the corresponding device status data. To achieve real-time interaction between BIM data and IoT data, it is necessary to build a mapping relationship between the model and the IoT device. There are currently two methods for building mapping relationships:

[0003] The first method is to generate component IDs in Revit when building a BIM model, and add IoT device IDs at the same time to achieve a one-to-one mapping between BIM component IDs and IoT device IDs, thereby realizing real-time data interaction.

[0004] The second method is to add the BIM component ID to the data dictionary of the IoT device to achieve a one-to-one mapping between the IoT device ID and the BIM component ID, and realize real-time data interaction during the 3D visualization development process.

[0005] This shows that current data exchange methods, whether for BIM source data or IoT source data, are highly dependent, highly coupled, and difficult to dynamically scale.

[0061] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0063] It should be understood that although the terms first, second, etc. may be used to describe various functional modules in embodiments of the present invention, these functional modules should not be limited to these terms. These terms are only used to distinguish functional modules of the same type from each other. For example, without departing from the scope of embodiments of the present invention, the first call module may also be referred to as the second call module, and it is not necessarily required or implied that there is any such actual relationship or order between these entities or operations. Similarly, the second call module may also be referred to as the first call module.

[0064] Traditionally, BIM equipment management only supports viewing static property information of buildings and equipment, as well as equipment operation and maintenance records, within a 3D model. It doesn't support visually viewing real-time equipment status data within the BIM model. This application addresses the need to quickly map device component IDs to IoT devices. This application defines unified coding standards during the BIM modeling and IoT device design phases, and implements these unified device coding standards during the implementation phase to achieve logical mapping. Specifically, equipment can be coded according to the Ministry of Housing and Urban-Rural Development's national standard GB / T51269-2017, "Classification and Coding Standard for Building Information Modeling."

[0065] The implementation of the present invention is described in detail below with reference to specific embodiments.

[0066] Figure 1A flow chart of a real-time interaction method based on BIM data and IoT data provided by the first embodiment of the present invention is shown. Figure 6 , the embodiments of the present invention are described in detail below.

[0067] A real-time interaction method based on BIM data and Internet of Things data, the method comprising the following steps:

[0068] Step S100: Identify the device status data acquired in real time and build a device status database.

[0069] Specifically, sensors for obtaining different device states are set according to the functional state of the device; for example, temperature sensors, current sensors, smoke sensors, etc., wherein the temperature sensor is used to obtain the temperature of the device or the device working environment, and the current sensor is used to obtain the working current of the device; then the device state data obtained at different time points are identified to facilitate the construction of a device state database.

[0070] The identifier of the device status data may be a code that can represent the device number, device location, and device status at a certain moment.

[0071] Step S200: Establish a BIM model and perform component processing on the BIM model state data to obtain identical components in the BIM model.

[0072] Specifically, a BIM model of a building is established in Revit three-dimensional modeling through manual modeling.

[0073] It is understandable that different types of equipment need to be installed in buildings, such as electrical equipment, fire-fighting equipment, security equipment, etc. By generating component IDs in Revit when building BIM models, each component ID represents an equipment model of the same category or with the same function.

[0074] Step S300: construct a BIM database and identify the BIM model status data of the component.

[0075] Specifically, the method for identifying the BIM model status data of a component is: when the equipment model in the BIM model generates an identification, obtaining a set of attribute information of the equipment model in the BIM model; wherein the attribute information set includes multiple attribute information of the equipment model in the BIM model; extracting at least two attribute information from the attribute information set; generating an identification of the equipment model in the BIM model based on the at least two attribute information, and using the generated identification of the equipment model in the BIM model as the status data identification of the BIM model.

[0076] Step S400: establishing an interactive connection between the open interface of the BIM database and the open interface of the equipment status database.

[0077] Specifically, by establishing an interactive connection between the open interface of the BIM database and the open interface of the equipment status database, data can be read, modified, and stored bidirectionally in the BIM database and the equipment status database. Specifically, the BIM database and the equipment status database exchange data through WebService technology.

[0078] Step S500: storing an association mapping relationship table between the device status data identifier of a single device and the BIM model status data identifier of the same component, and updating the association mapping relationship table in real time.

[0079] Specifically, by pre-setting an association mapping relationship table between the device status data identifier of a single device and the BIM model status data identifier under the same component, and then storing the association mapping relationship table in the system, when the device status data obtained in real time changes, the BIM model status data corresponding to the identifier is found through the identifier of the device status data and the association mapping relationship table, so as to realize real-time adjustment and display of the BIM model status.

[0080] Step S600: Process the real-time progress status of the equipment into BIM model status data according to the association mapping relationship table, and drive the BIM model to display it in a specific manner.

[0081] The display in a specific manner includes flashing or highlighting.

[0082] Specifically, according to the real-time progress status of the equipment, its corresponding identifier is matched in the equipment status database, and then according to the association mapping relationship table, the BIM model status data corresponding to the identifier of the equipment status data is found, and finally the BIM model is driven according to the BIM model status data so that the BIM model displays the status according to the BIM model status data.

[0083] The above-mentioned real-time interaction method based on BIM data and IoT data constructs an equipment status database and a BIM database, and establishes an interactive docking of data between the equipment status database and the BIM database. At the same time, through the association mapping relationship table between the equipment status data identifier of the storage device and the BIM model status data identifier under the same component, real-time interaction of BIM data and equipment status data can be achieved, thereby improving the efficiency of data interaction. At the same time, the data interaction method has a low coupling degree, which reduces the difficulty of data interaction.

[0084] The following is a specific example to further illustrate the real-time interaction method based on BIM data and Internet of Things data provided by the present invention.

[0085] See also Figure 2 , based on the first embodiment, Figure 2 FIG. 1 is a schematic diagram showing a specific flow of step S100 in a real-time interaction method based on BIM data and IoT data provided by a second embodiment of the present invention. It should be noted that, in this embodiment, step S100 specifically includes the following steps:

[0086] Step S101: Obtain the device code and location code of the device, and record the device timestamp when receiving data from the device.

[0087] Specifically, a device code is a type of device identifier, which can be a pre-set device number. A location code can be the device's geographic location number or the number of its logical location determined by a base station. A device timestamp is generated using digital signature technology when acquiring device status data. The signature object includes information such as the original file information, signature parameters, and signing time. The device timestamp system is used to generate and manage device timestamps. It digitally signs signed objects to generate device timestamps, proving that the original file existed before the signing time.

[0088] Step S102: Generate a device status data code according to the device code and the device timestamp.

[0089] Among them, the status data code of the equipment consists of the equipment code and the timestamp when the data is received. In this way, the status information of the equipment model and the real-time status data of the physical equipment can be mapped to each other according to the compiled equipment code and status data code, thereby achieving the mapping of the BIM database and the equipment status database. While rendering the equipment model in the platform, through the associated mapping of the equipment code and status data code of the associated equipment, the API interface is flexibly applied to retrieve the equipment status data and display it on the equipment in the model. In this way, the real-time status data of the equipment can be viewed in real time in the model, achieving more timely and accurate control.

[0090] Step S103: storing the status data code and the position code corresponding to the device in a device status database.

[0091] It should be noted that the device status data code and position code are both identification information of the device. Specifically, the device status data is identified by storing the status data code and position code corresponding to the device in the device status database.

[0092] See also Figure 3 , based on the first embodiment, Figure 3FIG. 3 is a schematic diagram showing a specific flow of step S300 in a real-time interaction method based on BIM data and IoT data provided by a third embodiment of the present invention. It should be noted that, in this embodiment, step S300 specifically includes the following steps:

[0093] Step S310: Obtain the component code and spatial position code of the component, and record the component timestamp when the data of the component is received.

[0094] Specifically, a component code is a type of component identifier, which can be a pre-set component number. A spatial location code can be the number of the spatial location of a device model in the BIM model. A component timestamp is data generated using digital signature technology when acquiring BIM model status data. The signature object includes information such as the original file information, signature parameters, and signature time. The component timestamp system is used to generate and manage component timestamps. It digitally signs the signature object to generate a component timestamp to prove that the original file existed before the signing time.

[0095] Step S320: Generate a spatial state data code of a component according to the component code and the component timestamp.

[0096] Among them, the spatial status data encoding of the component consists of the component code and the timestamp when the status data is displayed. In this way, the status information of the equipment model and the real-time status data of the physical equipment can be mapped to each other according to the compiled equipment code and status data code, thereby achieving the mapping of the BIM database and the equipment status database.

[0097] Step S330: storing the spatial state data code and the spatial position code corresponding to the component in a BIM database.

[0098] It should be noted that the spatial status data code and spatial position code are both identification information of the component. Specifically, the BIM model status data of the component is identified by storing the status data code and position code corresponding to the component in the equipment status database.

[0099] In another specific embodiment, obtaining the component code and spatial position code of the component specifically includes:

[0100] The status data and location data corresponding to the equipment model in the BIM model are obtained respectively, and classified and coded respectively.

[0101] See also Figure 4 , based on the third embodiment, Figure 4FIG. 4 is a schematic diagram showing a specific flow of step S310 in a real-time interaction method based on BIM data and IoT data provided by a fourth embodiment of the present invention. It should be noted that, in this embodiment, step S310 specifically includes the following steps:

[0102] Step S311: Acquire location data corresponding to the equipment model in the BIM model.

[0103] Specifically, the above-mentioned location data represents the location information of the equipment model in the BIM model. The location information can be pre-set according to the actual location of the equipment in the building when establishing the BIM model.

[0104] Step S312: Acquire the status data of the equipment model in the normal state in the BIM model through the Internet.

[0105] Specifically, the state data of the equipment model under normal conditions is obtained through the Internet. For example, by accessing the official website of the fire-fighting equipment manufacturer, the state data of the fire-fighting equipment under normal conditions in standby mode is obtained and imported into the equipment model of the BIM model as normal state data. The normal state data includes at least water pressure data of the water pump, air pressure data of the fire-fighting water pipe, and data of at least one valve in normal state.

[0106] Step S313: Classify and encode the equipment models in the BIM model using a classification model generation method.

[0107] Specifically, the device models in the BIM model are first obtained, and then the device models in the BIM model are classified and coded using a classification model generation method. The device models are categorized into electrical equipment, firefighting equipment, security equipment, etc., based on the type of equipment, and different types of device models are coded differently.

[0108] See also Figure 5 , based on the fourth embodiment, Figure 5 FIG. 5 is a schematic diagram showing a specific flow of step S311 in a real-time interaction method based on BIM data and IoT data provided by a fifth embodiment of the present invention. It should be noted that, in this embodiment, step S311 specifically includes the following steps:

[0109] Step S3111: Send a request through the system to obtain location data information, and determine the ID of the first-level area where the current device model is located based on the current location of the model, wherein the first-level area includes multiple second-level sub-areas;

[0110] Step S3112: sequentially traverse the second-level sub-regions to the N-th-level sub-region included in the first-level region where the current position is located to determine the ID of the N-th-level sub-region corresponding to the current position; where N is a positive integer greater than or equal to 2;

[0111] Step S3113: Acquire the location data of the device model corresponding to the N-th level sub-area according to the ID of the N-th level sub-area.

[0112] In some other embodiments, the classification model generation method includes:

[0113] Obtain the equipment model in the BIM model, extract at least one ID of the equipment model in the BIM model, and use each ID of the equipment model and the classification label corresponding to the equipment model as a set of first training data; generate at least one transformed image corresponding to the equipment model, and use each transformed image corresponding to the equipment model and the classification label corresponding to the equipment model as a set of second training data; train the initial classification model according to each set of first training data, and generate a basic classification model respectively; train the initial deep learning model according to each set of second training data, and generate a basic classification model respectively; and the basic classification models together constitute a classification model of the equipment model in the BIM model.
