Description

Technical Field

[0001] The present application relates to the field of information and digital technology, and in particular to a method for constructing a spatiotemporal object and related equipment. Background Art

[0002] Digital twin technology synchronizes virtual and real life by creating digital representations of physical objects. It uses sensors, the Internet of Things, virtual reality, artificial intelligence, and other technologies to describe and model the characteristics, behaviors, operational processes, and performance of real-world physical objects. By integrating data from multiple sources, including real-time and historical data, and leveraging principles, mechanisms, and process models, digital twins create a digital model that accurately reflects the state of physical objects in real time, providing users with real-time feedback and interaction.

[0003] Traditional spatiotemporal modeling methods are typically designed for data and problems in specific domains. However, spatiotemporal data in different domains has its own unique characteristics and patterns. For example, event data changes frequently and the data volume is large; the spatiotemporal relationships between spatiotemporal objects at a given moment are complex and changeable. Due to the differences in spatiotemporal data characteristics, it is difficult to uniformly and effectively model spatiotemporal data with different characteristics. This requires the construction of models with different data structures, and the model types are numerous and inconsistent, making them unsuitable for the twin of everything.

[0004] In view of this, it is necessary to provide a new method for constructing space-time objects and related equipment to solve the above problems. Summary of the Invention

[0055] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0056] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0057] It will also be understood that the term “comprising” indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements and / or components.

[0058] "And / or" is used to describe the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0059] Traditional spatiotemporal modeling methods involve multiple fields and technologies, aiming to capture and analyze data changes in space and time. Traditional modeling methods include the following:

[0060] (1) The spatiotemporal composite modeling method converts each independent overlay operation into a one-time composite overlay. The accumulated changes form the smallest change unit. The graphic files composed of these smallest change units are linked together with the attribute files that record the change history to express the spatiotemporal characteristics of the data. The main disadvantages of this spatiotemporal composite modeling method are polygon fragmentation and excessive reliance on relational databases. As changes become more frequent, a lot of fragments will be formed.

[0061] (2) The continuous snapshot model method records a series of snapshots of time segments in the database to reflect the spatiotemporal evolution of geographical phenomena. However, the main disadvantage of the continuous snapshot model method is that it has high data redundancy. When events change frequently and the data volume is large, the system efficiency drops sharply.

[0062] (3) The base state correction model method only stores the data state at a certain point in time (base state) and the change relative to the base state. Although the base state correction model method avoids the data redundancy problem of the continuous snapshot model, its main disadvantage is that it is difficult to handle the spatial relationship between spatiotemporal objects at a given moment, and it is very inefficient when retrieving states in the distant past.

[0063] (4) The space-time cube model method uses geometric solids to represent the process of two-dimensional graphics developing and changing along the time dimension, marking time at spatial coordinate points. However, the main disadvantage of the space-time cube model method is that the gradual changes in space over time cannot be represented in the space-time object model, and there is no concept to describe the change and process.

[0064] In view of the shortcomings of the above-mentioned traditional spatiotemporal modeling methods, the present application provides a method for constructing spatiotemporal objects. This method can construct a universal, effective and highly reusable twin structure, and spatiotemporally objectify the physical entities in the objective world. The generated spatiotemporal objects have a unified and complete structure, have time and space reference attributes, can construct a spatiotemporal object parent-child structure, and can organize data through spatiotemporal objects.

[0065] For example, a specific group, a factory within the group, or a workshop within the factory can all be twinned into a specific spatiotemporal object. Physical spacetime in the objective world can organize any other physical entities and processes, such as a part or semi-finished product within a workshop, an assembly event on a production line, or the organization and personnel within a factory. The state of any physical entity or process in the objective world can be determined by a specific moment and spatial location. Therefore, spatiotemporal objects possess three basic characteristics: attributes, space, and time. These characteristics enable spacetime to play a key role in organizing the changes of other physical entities and processes. Spacetime refers to the spatiotemporal scope within which a physical entity resides. Any other physical entity within this scope adheres to the temporal and spatial constraints of the spatiotemporal object. Each physical entity and process possesses unique attributes that distinguish it from other physical entities and processes.

[0066] For further information, see Figure 1 As shown, Figure 1 The operating system of the method for constructing an empty object provided in this application includes three modules: a time coordinate system object construction module 101, a space coordinate system object construction module 102, and a space-time object creation module 103, wherein:

[0067] Time coordinate system object construction module 101: It can create a time coordinate system object in the model library according to business needs. A time coordinate system object can be created for each spatiotemporal object to describe the time reference properties of the spatiotemporal object. Any other business object within the spatiotemporal range shares the time coordinate system object.

[0068] Spatial coordinate system object construction module 102: It can create spatial coordinate system objects in the spatial library according to business needs. It can create a spatial coordinate system object for each spatiotemporal object to describe the spatial reference properties of the spatiotemporal object. Any other business object within the spatiotemporal range uses the same spatial coordinate system object.

[0069] The spatiotemporal object creation module 103 creates spatiotemporal copies within the model library, adds the spatiotemporal copies from the model library to the spatiotemporal library, and creates spatiotemporal objects within the spatiotemporal library, such as the real-time library or the historical library. Once the spatiotemporal object is created, any business object can be created within the spatiotemporal object.

[0070] Based on the above operating system, see Figure 2 As shown, the embodiment of the present application provides a method for constructing a spatiotemporal object, and the specific process includes:

[0071] Step S201: Construct at least one physical entity set.

[0072] Step S202: for at least one physical entity set, respectively establish a spatiotemporal object for the at least one physical entity set.

[0073] Among them, all physical spatiotemporal entities in each physical entity set have the same parameter structure; and the parameter structure associated with the corresponding physical entity set is defined in each spatiotemporal object.

[0074] The spatiotemporal object includes a spatiotemporal range attribute, which represents the spatiotemporal range of the corresponding physical spatiotemporal entity, and all physical objects within the spatiotemporal range are subject to the constraints of the spatiotemporal range; the physical object in this application is the digital twin of the physical object.

[0075] In a possible implementation, the spatiotemporal range attribute includes a time attribute, which indicates that physical objects within the spatiotemporal range share a time coordinate system, and the time coordinate system indicates a start time on an absolute time axis.

[0076] In one possible implementation, during the construction of the spatiotemporal object of the present application, a time coordinate system for each of the spatiotemporal objects of the at least one physical entity set is established respectively; in response to a time coordinate reference instruction, the time coordinate reference instruction includes a time coordinate system identifier corresponding to each spatiotemporal object; the time coordinate system corresponding to each time coordinate system identifier is obtained, and the obtained time coordinate system is referenced to the corresponding spatiotemporal object, and the referenced time coordinate system is used as a time reference for the physical object within the above-mentioned spatiotemporal range.

[0077] Furthermore, the time coordinate system divides the time axis into N consecutive periods according to the periodic time rule, and the start time of each period is not less than a preset time, where N is a positive integer.

[0078] In a possible embodiment, the time coordinate system is stored in the model library in this application. First, the time coordinate system is created in the model library. When creating a spatiotemporal object, the time coordinate system can be referenced as a time reference for other physical objects within the spatial range.

[0079] The spatiotemporal object is associated with the time coordinate system. The time coordinate system has no model and copy. Creation is the object. The time coordinate system is stored in the warehouse of the model library. The time coordinate system describes the start of a time point on the absolute time axis (start time). The time axis is divided into countless continuous periods according to the periodic time rule. The start time is not less than the set value. For example, the start time is not less than 1601-1-10:0:0 value.

[0080] In a possible implementation, the spatiotemporal range attribute includes a time range attribute, which represents the time range of the spatiotemporal object in the referenced time coordinate system, and all physical objects within the spatiotemporal range are within the time range.

[0081] In the embodiment of the present application, the spatiotemporal object has a time range attribute, which is used to characterize the time range of the spatiotemporal object. Optionally, the time range is set to a datetime type value, specifying the start time and end time, indicating that all other physical objects within the spatiotemporal range are within the time range. When performing data operations, such as querying data within a specified time range, the specified time range must be within the time range of the spatiotemporal object.

[0082] In a possible implementation, the spatiotemporal range attribute includes a spatial attribute, where the spatial attribute represents that physical objects within the spatiotemporal range share a spatial coordinate system, and the spatial coordinate system represents a spatial reference attribute of the spatiotemporal objects.

[0083] In an optional embodiment, the spatial coordinate system in this application is stored in a spatial library. First, a spatial coordinate system is created in the spatial library. When creating a spatiotemporal object, the spatial coordinate system can be referenced as a spatial reference for other physical objects within the spatial range.

[0084] In one possible implementation, during the construction of the spatiotemporal object of the present application, a spatial coordinate system for each of the spatiotemporal objects of at least one physical entity set is established for each of the spatiotemporal objects of the above-mentioned at least one physical entity set; in response to a spatial coordinate reference instruction, the spatial coordinate reference instruction includes a spatial coordinate system identifier corresponding to each spatiotemporal object; the spatial coordinate system corresponding to each spatial coordinate system identifier is obtained, and the obtained spatial coordinate system is referenced to the corresponding spatiotemporal object, and the referenced spatial coordinate system is used as a spatial reference for the physical object within the spatiotemporal range.

[0085] It is worth noting that the types of spatial coordinate systems in this application include at least one of the following: a Cartesian coordinate system, a geodetic coordinate system, and a projected coordinate system, wherein:

[0086] Cartesian coordinate system: A coordinate system that has no geographical meaning, is usually infinite, and has no units.

[0087] Geodetic coordinate system: basically, it is a spherical coordinate system based on the earth's ellipsoid that has been defined by countries and standard organizations. It is defined by a datum plane, an angular measurement unit (usually degrees) and a prime meridian. The units are usually longitude and latitude.

[0088] Projected coordinate system: A projected coordinate system based on a geodetic coordinate system, such as a map projection like Transverse Mercator, Albers Equal Area, or Robinson. These map projections (and various other map projection models) provide various mechanisms for projecting maps of the Earth's spherical surface onto a two-dimensional Cartesian coordinate plane. A projected coordinate system, sometimes called a map projection, consists of a linear unit of measure (usually meters or feet), a map projection, the specific parameters used by the map projection, and a geographic coordinate system.

[0089] In a possible implementation, the spatiotemporal range attribute includes a coordinate axis range attribute, and the coordinate axis range attribute represents the coordinate range of the coordinate axis of the spatiotemporal object in the referenced spatial coordinate system.

[0090] In an optional embodiment, the spatiotemporal object has x, y, and z axis range attributes, which represent the coordinate range of the spatiotemporal object on the x, y, and z axes in the referenced coordinate system. All arbitrary entity objects within the range of the spatiotemporal object cannot exceed this range.

[0091] In one possible implementation, the spatiotemporal range attribute includes a parent spatiotemporal attribute, which indicates that a parent-child relationship can be established between at least two spatiotemporal objects; the spatiotemporal object construction method of the present application also includes: if a parent-child relationship exists between at least two spatiotemporal objects, the spatiotemporal object representing the parent spatiotemporal attribute is identified as the parent spatiotemporal object; based on the parent spatiotemporal object and in combination with the parent-child relationship, at least one child spatiotemporal object is associated with the parent spatiotemporal object.

[0092] The at least one child spatiotemporal object is another spatiotemporal object other than the parent spatiotemporal object among the at least two spatiotemporal objects.

[0093] The spatial range of the parent spatiotemporal object is greater than or equal to the spatial range of all the child spatiotemporal objects.

[0094] In the embodiment of the present application, the relationship between the whole and the part, the inclusion and the included, between two independent space-time objects is called a "parent-child relationship". There is a parent-child relationship between two independent space-time objects, which we also call the child space-time within the spatial scope of the parent space-time. A certain space-time object may or may not have a parent space-time object and / or a child space-time object. The parent space-time object can include 0 or more child space-time objects; the time range of the parent space-time object is not less than the time range of the child space-time object; the spatial range of the parent space-time object is not less than the spatial range of all child space-times. This relationship is not a master-slave relationship, but a mutual relationship between the time range and spatial range of two individual space-time objects of equal status. For example, a factory and a warehouse, the factory includes a space-time range, and the warehouse also includes a space-time range. The warehouse space-time object and the factory space-time object have a parent-child relationship.

[0095] For example, see Figure 3 As shown, Figure 3 A schematic diagram showing the parent-child relationship of spatiotemporal objects in the spatiotemporal database. After creating spatiotemporal objects in the spatiotemporal database, you can build parent-child relationships of spatiotemporal objects based on business needs, such as Figure 3 As shown, the spatiotemporal objects of factory, workshop 1, workshop 2, production line 1, and production line 2 are constructed, and the child spatiotemporal objects of the factory spatiotemporal object are workshop 1 and workshop 2; the child spatiotemporal objects of workshop 1 are production line 1 and production line 2. The parent-child relationship between spatiotemporal objects can be achieved through Figure 4 express.

[0096] It should be noted that in this application, a parent-child relationship can be established between spatiotemporal objects. Spatiotemporal objects can exist independently. A spatiotemporal object can also contain one or more child spatiotemporal objects. A child spatiotemporal object can only have one parent spatiotemporal object.

[0097] In a possible implementation, the spatiotemporal range attribute further includes a spatiotemporal position attribute, which represents the spatiotemporal position of a physical object that can be located within the spatiotemporal range of the spatiotemporal object.

[0098] For example, any physical object within the scope of a spacetime object has:

[0099] <1> The coordinate position attribute of point3d;

[0100] <2> Represents the envelope properties of the point3d envelope start point and point3d envelope end point of the entity object;

[0101] <3> Attributes that represent the geometry of a physical object.

[0102] The point3d coordinate position of a physical object represents the coordinates of the physical object within the time and space range; the envelope attribute represents the envelope range of the physical object; and the geometric shape attribute represents the shape of the physical object, such as a sphere or a cylinder.

[0103] See Figure 5 As shown, Figure 5 Two physical objects are used as an example, showing the spatial location attributes of physical object 1. Figure 5 It can be seen that the spatial position coordinates of object 1 are (2, 3, 0), the position coordinates of the envelope starting point are (2, 6, 0), and the position coordinates of the envelope end point are (4, 3, 0).

[0104] Furthermore, in the example of this application, if any physical object is moved from the spatiotemporal range of the spatiotemporal object where it is located to the spatiotemporal range of the target spatiotemporal object, the spatiotemporal position of any physical object is modified to the target spatiotemporal object.

[0105] Any physical object can belong to a certain space-time range, and some physical objects can move within different space-time ranges. At this time, the space-time object has the characteristic of "position". This application uses space-time position to express it. For example, if a part moves from the space-time range of a warehouse to the space-time range of a workshop, the part is expressed as an arbitrary physical object, and the warehouse and workshop are expressed as space-time objects.

[0106] For example, see Figure 6 As shown, Figure 6 The figure shows the location movement characteristics of spatiotemporal objects in the spatiotemporal library. After creating a spatiotemporal object in the spatiotemporal library, any physical object can be moved between different spatiotemporal locations according to business needs, such as Figure 6 As shown, the spare parts tire 1 and steering wheel 1 are moved from warehouse 1 to workshop 1.

[0107] From the above, we can see that spacetime objects can be used as "positions", that is, spacetime positions. Any other physical objects within the spacetime range can move within the spacetime range.

[0108] In one possible implementation, the above-mentioned spatiotemporal object also includes a unique identifier, which is used to uniquely map the corresponding physical spatiotemporal entity; or, the spatiotemporal object is set to allow customized names, and allows different spatiotemporal objects to be customized with the same name.

[0109] In this application, each spatiotemporal object is marked with a system-wide unique identifier. In one possible instance, a spatiotemporal copy is created in the model library and added to the runtime library, such as the real-time library. At this time, the copy can be used to create the spatiotemporal object; in the real-time library, the spatiotemporal object is created based on the spatiotemporal copy. When the spatiotemporal object is generated, the system automatically generates the GUID and ID of the spatiotemporal object. The name of the spatiotemporal object can be customized. The generated GUID and ID are unique in the entire system, and the spatiotemporal object name can be repeated.

[0110] In one possible implementation, the physical object in the present application includes at least one of the following attributes: a coordinate position attribute, which characterizes the coordinate position of the physical object in the time and space range; an envelope attribute, which characterizes the envelope range of the physical object in the spatial coordinate system, and the envelope range includes the envelope start point and the envelope end point; a geometric shape attribute, which characterizes the geometric shape of the physical object.

[0111] It can be concluded from the above embodiments that the spatiotemporal objects created in this application have the same spatiotemporal model structure, as shown in Table 1. As can be seen from Table 1, the structure of the spatiotemporal object includes the following parts:

[0112] (1) Unique identification (ID, GUID). This attribute maps the uniqueness of a physical entity in the objective world. The identification is unique in the entire system. The spatiotemporal object construction method in this application uses GUID and ID to mark the uniqueness of the physical entity. The name can be repeated.

[0113] (2) Time attribute (TRID), that is, time reference (time coordinate system), which represents that all other physical entities within the time and space range share a time coordinate system.

[0114] (3) Spatial attribute (SRID), that is, spatial reference (spatial coordinate system), which represents that all other physical entities within the time and space range share a spatial coordinate system.

[0115] (4) Parent spacetime attribute (spaceTimeID). This attribute indicates that a parent-child relationship can be established between spacetime objects, and a complete spacetime tree can also be constructed. A spacetime object can only have one parent spacetime object, and a spacetime object can have multiple child spacetime objects.

[0116] (5) Time range (timeSpan): This attribute represents the time span of the spatiotemporal object in the time coordinate system, indicating that any other physical objects within the spatiotemporal range are within the time range.

[0117] (6) x, y, z attribute range (xSpan, ySpan, zSpan), which represents the coordinate span range of the spatiotemporal object in the spatial coordinate system, indicating that any other physical object within the spatiotemporal range is within the coordinate span range.

[0118] (7) Spatiotemporal position characteristic. This attribute indicates that a spatiotemporal object can be used as a "position", that is, a physical object is at a certain spatiotemporal position at a certain moment, and can also move to different spatiotemporal positions. This characteristic is provided for physical objects within the scope of the spatiotemporal object.
