Detailed Description

For ease of understanding, the terms involved in the present application will be specifically explained first:

the object is: it may be a physical thing or a logical concept, and for example, the object may be an industrial device, a base station, a server cluster, an intelligent home system, an on-vehicle system, or the like.

The combined object is as follows: the present application relates to an aggregate formed by combining a plurality of objects, for example, if a smart television, a smart speaker, and a smart bulb are used as one object, a smart home system including the smart television, the smart speaker, and the smart bulb may be regarded as one combined object.

View: is a virtual table in the database whose contents are defined by queries, and it is also understood that a view is a structured query language (Structured Query Language, SQL) statement of a query stored in the database. As with the real data table, the view includes a series of named row and column data, but the view does not exist in the database in the form of stored data values, the row and column data in the view is from the data table to which the query defining the view applies, and is dynamically generated as the view is applied. The real data table only uses physical storage space, the view does not occupy the physical storage space, the view is only the existence of logical concepts, the data table can be modified immediately, but the view can only be modified by modifying created sentences.

In the scene of industrial internet of things, if attribute values detected by each sensor for equipment are respectively stored in a database, the database needs to be accessed for multiple times under the condition that the attribute values of multiple attributes of the equipment are required to be acquired, and even further, the attribute values of the multiple attributes of the equipment acquired by the database are integrated, so that the problem of low data acquisition efficiency exists. To solve this problem, the present application has been proposed.

The technical scheme to be protected of the application is described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of a data access system according to an embodiment of the present application, and as shown in fig. 1, the data access system includes a terminal 110 and a server 120 communicatively connected to the terminal 110. The terminal 110 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle-mounted device, a service terminal, etc., and is not particularly limited herein. The server 120 may be a physical server or a cloud server.

The server 120 deploys a database, where data such as an object data table of an object is stored, based on which the server 120 can provide a data access service related to the object for the terminal, that is, after receiving an object access request initiated by the terminal 110, the server 120 obtains, according to a target object identifier indicated by the object access request, an object data table corresponding to the target object from the database, and returns the object data table of the target object to the terminal 110.

In the present application, the data table of the object stored in the database includes attribute values of the object under a plurality of attributes. The attribute values of the object under the plurality of attributes are obtained by processing the reported information corresponding to the attributes according to the data processing mode configured for each attribute in the object model corresponding to the object.

The attribute of the object refers to a parameter for describing the object, and for example, the attribute may be temperature, humidity, operation duration, rotation speed, and the like. An object may be described under a plurality of attributes. For example, if the object is a numerically controlled machine tool, the properties of the object may be temperature, humidity, rotation speed, operating voltage, operating current, continuous operating time, etc.

The object model of the object may be obtained by performing model configuration on the administrator client, that is, the user may define, on the administrator client, an attribute for describing the object and a data processing manner corresponding to each attribute, and then the administrator client correspondingly uploads the object model obtained by configuration to the server 120.

The data access system further comprises a data acquisition device 130, wherein the reported information corresponding to each attribute of the object can be obtained by data acquisition of the data acquisition device, and the data acquisition device 130 comprises various sensors (a temperature sensor, a humidity sensor, a rotating speed sensor), an image acquisition device, an ammeter, a voltmeter, a flowmeter and the like. After the data acquisition device 130 reports the report information to the server, the server 120 may process the report information corresponding to each attribute according to the object model configured for the object and the data processing mode corresponding to each attribute, to obtain an attribute value corresponding to the object under each attribute; and integrating attribute values of the object under a plurality of attributes into an object data table of the object correspondingly.

Based on this, the server 120 may provide a data access service for the terminal based on the object data table of the stored object, and if the server 120 receives the object access request sent by the terminal 110, the server correspondingly obtains the object data table of the requested access object from the database, and since the object data table includes the attribute values of the object under a plurality of attributes, the terminal 110 may obtain the attribute values of the object under a plurality of attributes by initiating an access request, thereby improving the data obtaining efficiency.

Further, the user may configure a combined object model of the combined object at the administrator client, where the combined object model is used to indicate a plurality of objects included in the combined object and an association relationship between the plurality of objects. After the administrator client transmits the combined object model of the combined object to the server 120, the server 120 may correspondingly acquire an object data table of each object included in the combined object according to a plurality of objects included in the combined object indicated by the combined object model, and generate a combined object view of the combined object according to an association relationship between the plurality of objects indicated by the combined object model and the object data table of each object included in the combined object. Thus, if the terminal 110 initiates a combined object access request to the server 120, the server 120 may obtain a combined object view of the combined object and send the combined object view to the terminal 110. In this way, the terminal 110 can acquire the data of a plurality of objects associated with the combined object by initiating an access request once, thereby improving the data acquisition efficiency.

Fig. 2 is a flowchart of a data access method provided by the present application, which may be performed by the server in fig. 1, but may also be performed by other computing devices having processing capabilities. As shown in fig. 2, the method at least includes steps 210-230, which are described in detail below:

At step 210, an initiated object access request is received, the object access request including a target object identification of a target object.

The object access request refers to a request for accessing data related to an object, and in the present application, an object corresponding to the data requested to be accessed by the object access request is referred to as a target object, and the target object identifier refers to a request for uniquely identifying the target object.

Step 220, according to the target object identifier, obtaining an object data table corresponding to the target object, where the object data table includes attribute values of the target object under a plurality of attributes, where the attribute values of the target object under the plurality of attributes are obtained by processing the report information corresponding to each attribute according to a data processing manner corresponding to each attribute indicated by the object model corresponding to the target object.

The attribute of the object refers to a parameter for describing the object, and the corresponding attribute value of the object under the attribute can be understood as the parameter value of the corresponding parameter; attributes such as temperature, humidity, rotational speed, etc. Different objects, as well as different attributes used to describe the objects.

Information acquisition is generally carried out on an object through data acquisition equipment such as a sensor and the like, so that reporting information corresponding to the object under each attribute is obtained; reporting information corresponding to the attribute may also be understood as acquisition information acquired in the data acquisition device for indicating the corresponding attribute value. The data acquisition equipment can send the acquired report information to a server for temporary storage so as to facilitate the subsequent further processing of the report information based on the data processing mode corresponding to each attribute in the object model.

Because the data format of the data acquisition device is different from the data storage format required in the database, or the unit of the data acquired by the data acquisition device is different from the unit required for the attribute in the database, or the attribute value under an attribute is further calculated by the information acquired by a plurality of data acquisition devices, in this case, the reported information corresponding to the attribute may need to be further processed, and the processing result obtained by the further processing is taken as the attribute value corresponding to the attribute. The processing mode from the reported information corresponding to the attribute value is called as a data processing mode corresponding to the attribute. The data processing mode is, for example, a conversion mode that converts degrees celsius to degrees fahrenheit, and also, for example, a conversion mode that converts floating point type data to integer type data.

In the present application, a plurality of attributes of an object and a corresponding data processing method can be defined in advance according to actual needs, for example, attributes to be focused on for each object, a data storage format required by a database, a format and a unit of data acquired by a data acquisition device, and the like. The process of defining a plurality of attributes of the object and configuring a corresponding data processing mode for each attribute by a user according to the needs is a process of configuring an object model of the object. In a specific embodiment, the carrier of the object model may be a JSON-format configuration file, after which the configured object model is sent to the server.

In some embodiments, the attribute values of the object under the attribute may be determined according to the report information corresponding to the attribute through the following procedure of steps 201-203, and the attribute values under the plurality of attributes are updated into the data table corresponding to the object. Specific:

step 201, obtaining an object model of an object; the object model indicates a plurality of attributes defined for the object and a data processing mode corresponding to each attribute.

The object model of the object may be configured at the administrator client, and then the object model of the object and the object identifier of the object are associated and stored in the server, and then the object model of the object may be obtained from the server according to the object identifier of the object.

Fig. 2 illustrates a plurality of attributes defined for an object in an object model (i.e., attributes 1 to m, m being integers greater than 1) and data processing manners configured for each attribute (i.e., data processing manners B1 to Bm). In a specific embodiment, the attribute configured for the object in the object model and the data processing manner of the object may be configured according to actual needs. Further, the object model shown in fig. 2 further defines a type corresponding to each attribute, where the type is used to indicate a data type of an attribute value corresponding to an attribute in the object data table, and the data type includes an integer type and a floating point type, so that after determining the attribute value corresponding to each attribute, the attribute value can be stored in the object data table of the object according to the type corresponding to each attribute indicated by the object model.

Step 202, according to the data processing mode corresponding to each attribute, processing the report information corresponding to each attribute of the object to obtain the attribute value of the object under each attribute.

As described above, the reporting information corresponding to the attribute may be collected by the data collecting device and reported to the server by the collecting device. Therefore, the server can correspondingly acquire the reporting information corresponding to each attribute.

In some embodiments of the present application, the object model also indicates a source device identity corresponding to each attribute of the object; prior to step 202, the method further comprises: and acquiring reporting information corresponding to each attribute of the object in the reporting data set according to the source equipment identifier corresponding to each attribute.

The source equipment identifier corresponding to the attribute refers to the equipment identifier of the equipment from which the reporting information corresponding to the attribute is sent. And each piece of reporting information in the reporting data set is associated with the equipment identifier of the source equipment, so that the equipment identifier is matched based on the source equipment identifier corresponding to each attribute in the object model and the equipment identifier of the equipment from which each piece of reporting information in the reporting data set is derived, and the reporting information corresponding to each attribute is determined.

In some embodiments of the present application, reporting information in the reporting dataset is stored in a partitioned manner according to the source device; in this embodiment, the report information corresponding to each attribute may be obtained according to the following procedure: determining a storage position of the reported information corresponding to each attribute based on the corresponding relation between the equipment identifier and the storage position and the source equipment identifier corresponding to each attribute; and acquiring the reporting information corresponding to each attribute from the storage position where the reporting information corresponding to each attribute is located.

That is, the storage position of the report information of each device in the server is preset, and the storage position set for the device and the device identifier corresponding to the device are associated and stored. And after receiving the report information sent by the equipment, the server correspondingly stores the report information in a corresponding storage position. Based on the source equipment identification corresponding to each attribute in the object model, reporting information corresponding to the attribute is obtained from a storage position associated with the source equipment identification.

In some embodiments, the data processing manner corresponding to the attribute may be a conversion manner between data formats, that is, the data processing manner indicates a conversion manner between the original data format and the target data format; in this embodiment, step 202 includes: determining the original data format of the reported information corresponding to an attribute; and converting the format of the reported information corresponding to the attribute according to the conversion mode between the original data format and the target data format to obtain an attribute value of the attribute corresponding to the target data format.

In some embodiments, the data processing manner may indicate a conversion manner between multiple original data formats and a target data format, in which case, an original data format to which the reported information corresponding to an attribute belongs may be first identified, and then format conversion is performed on the reported information corresponding to the attribute according to the conversion manner between the original data format to which the reported information corresponding to the attribute belongs and the target format, so as to obtain an attribute value corresponding to the attribute.

In other embodiments, the data processing manner may indicate a conversion manner between an original data format and a target data format, in which case, the server determines that the data format to which the reported information corresponding to the attribute belongs is the original data format indicated by the data processing manner corresponding to the attribute, and performs format conversion according to the conversion manner indicated by the data processing manner, so as to obtain the attribute value corresponding to the attribute. Otherwise, if the server determines that the data format to which the reported information corresponding to the attribute belongs is not the original data format indicated by the data processing mode corresponding to the attribute, the server can send prompt information to the manager client. It can be understood that if the data format to which the reported information corresponding to the attribute belongs is not the original data format indicated by the data processing manner corresponding to the attribute, format conversion is still performed according to the conversion manner indicated by the data processing manner, which may result in inaccuracy of the obtained attribute value.

In other embodiments, the data processing manner corresponding to the attribute may be an extraction manner of extracting the attribute value from the corresponding report information. In this case, step 202 includes: and extracting the attribute value corresponding to the attribute from the reporting information corresponding to the attribute according to the extraction mode corresponding to the attribute.

For example, in some indoor environments, such as a laboratory, the working states of a plurality of test devices (corresponding to the test devices are objects, the working states are attributes) or the states of a certain component in the test devices may need to be concerned, an image acquisition device for performing image acquisition is deployed in the laboratory, and the report information corresponding to the working states is the images acquired by the image acquisition device and including the test devices; in this case, the data processing method corresponding to the attribute may be a recognition method for recognizing the operation state of the test equipment from the image including the test equipment. In a specific embodiment, the report information corresponding to different attributes may be the same, that is, it is equivalent to extracting the attribute values of at least two attributes from the same report information.

For another example, based on an image containing the test equipment, in addition to identifying the operating state of the test equipment, the degree of corrosion of the test equipment (which is positively correlated with the size of the area of the corroded region in the test equipment), and the state of the lubricating oil of the test equipment may be identified; in this case, from the reported information including the image of the test equipment, attribute values of three attributes, which are the operating state of the test equipment, the corrosion degree of the test equipment, and the state of the lubricating oil in the test equipment, are extracted, respectively. In other embodiments, the reporting information corresponding to the different attributes may also be different.

In a specific embodiment, the report information corresponding to an attribute may originate from one data acquisition device or may originate from a plurality of data acquisition devices. Under the condition that the reported information corresponding to the attribute is sourced from a plurality of data acquisition devices, the data processing mode corresponding to the attribute is used for further processing and calculating the reported information corresponding to the attribute to obtain the attribute value corresponding to the attribute.

And 203, integrating attribute values of the object under a plurality of attributes into an object data table corresponding to the object.

The object data table corresponding to the object is constructed according to the object model of the object. Specifically, according to a plurality of attributes of an object set in an object model, an attribute field for representing each attribute of the object and a field for representing an attribute value may be set in an object data table, so that after obtaining attribute values of the object under the plurality of attributes, the attribute values may be stored under the field representing the attribute value correspondingly. Further, if the object model further indicates a source device identifier corresponding to the attribute, the device identifier from which the attribute value is stored may also be correspondingly stored in the object data table.

In a specific embodiment, the data acquisition device may perform information acquisition at intervals and continuously send report information to the server, where the report information carries a timestamp, and the timestamp is used to indicate a time when the report information is acquired by the data acquisition device. In this case, the time stamp and the attribute value associations of the plurality of attributes under the time stamp may also be integrated into the object data table.

In some embodiments of the present application, after an object data table of an object is created according to an object model corresponding to the object, an access interface of the object data table may be generated, where the access interface of the object data table may also be understood as a uniform resource locator (Uniform Resource Locator, URL) of the object data table. And then, externally publishing the access interface of the object data table corresponding to the object, and storing the access interface in association with the object identification of the object. Based on this, in step 220, an access interface associated with the target object identifier may be obtained according to the target object identifier of the target object, and an object data table of the target object may be obtained correspondingly according to the access interface associated with the target object identifier. Therefore, the access address of the object data table corresponding to the object is provided directly, and the access address of the object data table can be obtained according to the target object identification in the object access request without searching the data table identification (such as the data table name) of the object data table and then searching the access address of the data table according to the data table identification, so that the efficiency of accessing the object data table can be further improved.

FIG. 3 is a schematic diagram of creating an object data table and generating an access interface according to an object model according to the present application. As shown in fig. 3, an attribute of each object and a data type corresponding to each attribute are defined in an object model 310, for example, for an attribute of "temperature", the set data type corresponding to the attribute is "int", the object model further defines a data processing manner corresponding to each attribute, then, based on the object model, a first SQL statement 320 for creating an object data table is generated, and then, the first SQL statement 320 is executed to create an object data table 330 of the object; thus, in step 203 of the corresponding embodiment of fig. 2, the attribute values of the obtained object under a plurality of attributes may be integrated into the object data table established for the object. Thereafter, an access interface of the object data table 330 is generated; thus, in step 220 of the corresponding embodiment of fig. 2, an access interface associated with the target object identifier may be determined based on the target object identifier, and the object data table of the target object may be correspondingly obtained according to the access interface.

After receiving the new report information flow 340, processing each report information in the report information flow 340 according to the data processing mode corresponding to each attribute indicated by the object model of the object, so as to obtain the attribute value of the object under each attribute. Thereafter, the attribute values of the plurality of attributes of the object under the same time stamp are integrated into the object data table 330 to update the data in the object data table.

Step 230, send the object data table of the target object to the client.

Because the object data table comprises attribute values of the object under a plurality of attributes, a user can know information of multiple aspects of the target object according to the object data table received by the client.

In the scheme of the application, the data processing modes corresponding to the attributes of the object are indicated through the object model of the object, the reported information corresponding to the attribute is processed according to the data processing mode corresponding to each attribute, the attribute value of each attribute is correspondingly obtained, and then the attribute values of the object under the attributes are associated and stored in the object data table. On the basis, after receiving an object access request initiated by a client, correspondingly acquiring an object data table of a target object requested to be accessed, and sending the object data table to the client, wherein the object data table comprises attribute values of the object under a plurality of attributes, so that the client can acquire the attribute values of the object under the plurality of attributes by initiating a request once, and the acquisition efficiency of the attribute values of the object under the plurality of attributes is effectively improved. In addition, as the plurality of attribute values are stored in the object data table after the reported information is processed, after the information related to the object is required to be accessed, the reported information is not required to be processed and data integration is performed after the request is received, so that the response time to the object access request is greatly shortened, the data acquisition efficiency is further ensured, and the user experience is improved.

In some application scenarios, a data processing device for collecting the report information may be newly added according to actual needs, in this case, if according to a data storage manner in the prior art, a program in a server is required to be updated, so as to ensure that the program in the server is adapted to the newly added data collecting device, for example, ensure that the server can accurately analyze the report information reported by the new data collecting device. In other words, according to the existing data storage mode, the server may need to be subjected to end-to-end adaptation and software upgrading to support access to the report information acquired by the newly added data acquisition device, which has the problems of large online difficulty and long online period of the new data acquisition device.

By adopting the scheme of the application, the problem can be effectively solved, and the object model of the object is correspondingly updated under the condition that the data acquisition equipment needs to be newly added, so that the reporting information corresponding to the new data acquisition equipment, the attribute corresponding to the reporting information of the newly added data acquisition equipment and the corresponding data processing mode are updated, and the data format of the reporting information acquired by the newly added data acquisition equipment and the format of the attribute value of the attribute corresponding to the reporting information in the object data table can be defined in advance through the object model, thereby, after the reporting information acquired by the newly added data acquisition equipment is received, the server can correspondingly analyze and further process the reporting information. It can be seen that by adopting the scheme of the application, the server is not required to be updated on a large scale, and the object model of the object is updated according to the requirement, so that the problems of high online difficulty and long online period of the novel data acquisition equipment in the prior art can be effectively solved.

Based on the object data table of each object generated in the corresponding embodiment of fig. 2, a combined object view of the combined object may be generated according to the association relationship between the plurality of objects included in the combined object indicated by the combined object model of the combined object and the object data table of the plurality of objects included in the combined object, and the combined object view of the combined object may be stored in association with the combined object identifier, so that a data access service related to the combined object may be provided to the terminal. Fig. 4 is a flowchart of a combined object view for generating a combined object according to the present application, and in fig. 4, each object data table in the database may be generated according to steps 201-203 of the corresponding embodiment of fig. 2 or steps 310-330 of the corresponding embodiment of fig. 3. As shown in fig. 4, the method further includes:

In step 410, a combined object model configured for the combined object is obtained, the combined object model indicating an association relationship between a plurality of objects included in the combined object and the plurality of objects.

The association relationship between the plurality of objects may be a parent-child relationship, a parallel relationship, or the like, and is not particularly limited herein, and of course, the hierarchical relationship between each object and the combined object may be further determined by the association relationship between the plurality of objects. The association relationship may be a relationship between objects established based on a certain attribute of the objects, or may be an association relationship between different objects defined in advance according to needs, for example, for a power grid system of a city a, where the city a includes an A1 region and an A2 region, and when the power grid system of the city a is taken as a combined object, the power grid system of the A1 region and the power grid system of the A1 region may be regarded as two objects included in the combined object, where the association relationship between the power grid system of the A1 region and the power grid system of the A2 region is a parallel relationship, and the parallel relationship is determined according to an administrative division of the A1 region and the A1 region.

A schematic diagram of a combined object model is shown in fig. 4, and as shown in fig. 4, the combined object model indicates that the combined object includes an object C1, an object C2, …, an object Cp (where p is a positive integer), and an object C2-1, an object C2-2, and an object C2-3, where the object C1, the object C2, …, and the object Cp are in a side-by-side relationship, and the object C2 is in a parent-child relationship with the object C2-1, the object C2-2, and the object C2-3. Further, object C1, object C2, …, and object Cp may also be understood as primary sub-objects of the combined object, and object C2-1, object C2-2, and object C2-3 may also be understood as secondary sub-objects of the combined object.

Step 420, obtain the object data table corresponding to each object included in the combined object.

Since the combined object model indicates a plurality of objects included in the combined object, an object data table of each object included in the combined object can be acquired from the database correspondingly according to the object identifications of the plurality of objects. The establishing of the object data table and the obtaining of the attribute values of the objects in the object data table under each attribute are described with reference to the corresponding embodiment of fig. 2, and are not repeated herein.

And 430, generating a combined object view corresponding to the combined object according to the association relation among the plurality of objects and the object data tables respectively corresponding to the plurality of objects included in the combined object.

In some embodiments, an SQL statement for generating a combined object view may be generated in advance according to a plurality of objects included in the combined object and association relationships between the plurality of objects indicated by the combined object model, and then in step 430, the SQL statement for generating the combined object view may be called to generate a combined object view corresponding to the combined object by using the association relationships between the plurality of objects and the object data tables respectively corresponding to the plurality of objects.

If the association relationship among the objects is established based on one or more attributes, the attribute on which the association relationship depends is called as the attribute corresponding to the association relationship. In this way, the association relationship actually indicates the attribute to be presented in the combined object view, that is, the attribute to be presented is the attribute to which the association relationship corresponds. Based on the attribute corresponding to the association relation, the data of the row or the column for indicating the attribute value under the attribute is acquired from the object data table of each object, and then the combined object view of the combined object is generated according to the data of the row or the column for indicating the attribute value under the attribute acquired from the object data tables of the plurality of objects.

In some embodiments of the present application, after generating a combined object view corresponding to a combined object, an access interface corresponding to the combined object view is generated and published, and correspondingly, in a case that a client needs to access the combined object, the combined object view of the combined object may be acquired based on the access interface corresponding to the combined object.

The object data tables of a plurality of objects are further integrated through the configured combined object model on the basis of taking the objects as units of data storage to obtain a combined object view of the combined objects, so that access service of the combined object view can be provided for the client based on the generated combined object view.

Specifically, the data access service for combining the object views of the objects can be provided for the client through the following processes, specifically including: receiving a combined object access request; the combined object access request includes a target combined identifier of the target combined object; acquiring a combined object view of the target combined object according to the target combined identifier; and sending the combined object view of the target combined object to the client. The combined object view may be generated according to steps 410-430 of the corresponding embodiment of fig. 4 based on the object data table stored in the database, and the object data table of the plurality of objects included in the combined object may be generated according to steps 201-203 of fig. 2, which are specifically referred to above and will not be described herein.

A combined object access request refers to a request for accessing data related to a combined object. In the present application, a composite object corresponding to data requested to be accessed by a composite object access request is referred to as a target composite object.

In some embodiments, if an access interface corresponding to a combined object view is published, an access interface corresponding to a target combined object may be determined according to a target combined identifier, and then, the combined object view of the target combined object is acquired correspondingly according to the access interface corresponding to the target combined object.

In some embodiments, on the basis of configuring an object model for an object and configuring a combined object model for a combined object, an access interface may be generated only for the object data table, or may be generated only for the combined object view, or may be generated for both the object data table and the combined object view, and may be specifically set according to actual needs.

FIG. 5 is a schematic diagram illustrating generating a combined object view and generating an access interface from a combined object model, according to an embodiment of the present application. In step 430 of the corresponding embodiment of fig. 4, a combined object view may be generated in accordance with the process shown in fig. 5. As shown in fig. 5, based on a combined object model 510 configured for the combined object, a second SQL statement 520 for creating a combined object view corresponding to the combination is then generated according to the association relationship between the plurality of objects indicated by the combined object model, so as to correspondingly generate the combined object view of the combined object based on the second SQL statement 520. Then, a second access interface 530 corresponding to the combined object view is generated, and the second access interface 530 is issued. Therefore, in the case that the client needs to access the data related to the combined object, the second access interface associated with the combined object identifier may be determined according to the combined object identifier of the target combined object requested to be accessed, and then the combined object view of the target combined object requested to be accessed is correspondingly acquired through the second access interface 530.

In the combined object processing step, a combined object model is obtained from an object model configuration file, a combined object view corresponding to the combined object is created in a first database, and a second azimuth interface corresponding to the combined object view is issued to a data access interface.

In the caching process 720, after the edge computing device receives the data stream from the data acquisition device, the edge computing device caches the data stream according to the data source partition, that is, according to the source device identifier corresponding to each piece of reporting information in the data stream, and stores the corresponding piece of reporting information in the storage partition corresponding to the source device identifier.

In the data integration process 730, a base object processing step is performed. Specifically, in the basic object processing step, the information reported in the access cache is periodically reported, and the following steps are sequentially executed: acquiring reporting information corresponding to each attribute according to the source equipment identifier corresponding to each attribute; and performs steps 201-203 above. Further, after completing the data integration process of one period, the edge computing device may synchronize the object data table and the combined object view in the first database to the second database in the cloud, so that the cloud server may further combine the object data table or the combined object view.

In addition, an access interface of the object data table is also provided, so that the object data table of the object can be accessed according to the access interface in the data access process. In the application, because the reported information is not required to be processed in the data access process, and then the integration of a plurality of attribute values is carried out, the reported information is processed and integrated before being stored, which is equivalent to the process logic of integrating the data processing and the attribute values carried out in the application layer in the prior art to be moved down to the data layer, thereby, the client can access the attribute values of the object under a plurality of attributes based on one request without carrying out additional processing, realizing the separation of the application and the data and improving the efficiency of data access.
