The industrial internet platform provides a variety of applications for users to meet the requirements of the users, such as device resource management applications, big data analysis applications, data visualization applications, and the like. Each application in turn requires the cooperation of multiple resource entities. Taking the device resource management application as an example, physical resources with different specifications, different types and a large number need to be communicated and connected with the industrial internet platform, digital modeling needs to be performed on the industrial internet platform aiming at the physical resources, and the physical resources are indirectly controlled through the operation of the digital model.
The open resource management model of the embodiment defines a set of abstract resource management model by taking industrial internet platform resources as objects, realizes description and modeling of the industrial internet platform resources, and reduces the workload of platform developers and managers.
The method has the advantages that various resources are connected and communicated with each other in an industrial internet platform, the relationship among the various resources is complicated, and the problem is that no unified resource description and modeling method exists at present, so that the different types of resource description modes are different greatly, developers cannot quickly and correctly understand the specific meanings represented by the various resources in the platform and the relationship among the various resources, the resource development speed is reduced, and the resource management is disordered. The invention takes industrial internet resources as objects to establish a model, provides a universal resource abstract model, a standard interface and an SDK development kit for realizing each resource end of the standard interface for the management of various resources; the method provides connection, management service and control interface based on the abstract model for the back end of the industrial internet platform, decouples the relation between a specific resource and a specific platform, and greatly simplifies the earlier stage work of developers and managers. The technical solution of the present invention will be described in detail with specific examples.
Example one
The open resource management model of the embodiment includes:
the application layer is used for providing an operable interface for a user, analyzing the user requirement, transmitting the user requirement to the resource layer, and receiving the response feedback of the resource layer to the user;
the resource layer is used for receiving the application layer requirements and responding, the resource layer establishes a plurality of resource classes according to different data types, one resource is modeled into one resource class, each resource class comprises one or more resource instances, and each resource instance is provided with a unique identification address;
the resource class management server is used for providing services of creating, compiling and deploying the published resource classes for the user;
a resource class database for storing resource classes;
a resource instance database for storing resource instances;
the resource instance running server is used for mapping the resource entities into resource instances; the resource instance running server is used for executing the operation on the resource instance;
the resource instance management server is used for acquiring resource classes from the resource class database and providing services for creating, compiling and deploying and releasing resource instances for users;
a resource instance monitoring server for creating, publishing, stopping or invalidating the resource instance.
The scheme also comprises a user layer, which is used for various users using the model to use the interface provided by the application layer to put forward the requirements to the application layer, and the users can communicate with the application layer through a wired or wireless network so as to complete the required work.
The calling requirement is issued through the abstract model interface or the platform function module, and the problem that industrial internet platform resources are closed and not opened is solved.
Resources in the industrial internet platform are not available to any resource and any user, and various resources must be fully mobilized to improve the working efficiency and the resource utilization rate. The open resource management model of the scheme is open to the outside through a standard interface in the abstract model, and the security is considered, including the security of access identity authentication, the security of data transmission, the security of back-end control, the migration of faults and the like.
As shown in fig. 1, taking the home appliance manufacturing industry as an example, the resource may be embodied as a temperature sensor in the refrigerator manufacturing process. In the manufacturing process of the refrigerator, a plurality of temperature sensors of the same manufacturer and the same model are used, the temperature sensors of the same type are abstracted into a model, the model is subjected to standardized description, and the model is stored in a resource model server. Each temperature sensor used has a mirror image stored in the instance server, and the mirror images are instantiations of the temperature sensor model. When the terminal sends a certain instruction, for example, a manufacturer wants to adjust the temperature of the temperature sensors, the interface provided by the application layer needs to be clicked, the application layer calls the interface provided by the model layer, the unique ID identification of the resource instance is used for finding the instance mirror image of the corresponding temperature sensor, and the mirror image responds to the operation and transmits the instruction to the temperature sensor entity. The following core concepts are proposed based on the above model:
1) RC (resource class) resource class, which is defined at the server end and is a digital modeling of resources;
2) RI (resource instance) resource instances, instantiating the generated instance objects according to the resource class;
3) an RIRS (resource Instance Runtime Server) resource Instance running server, wherein the operation on the RI is carried out on the server;
4) RCMS (resource Class manager Server) resource Class management server;
5) an RIMS (resource Instance manager Server) resource Instance management server;
6) RIMNS (resource Instance Monitor Server) resource Instance monitoring server;
7) RCDB (resource Class DataBase) resource Class database;
8) RIDB (resource Instance database) resource Instance database.
When the resource class management server publishes and deploys the resource classes, a resource end running library based on C/Java is generated, and the resource end running library can be downloaded.
The resource-side runtime library comprises any combination of a base library, a resource data type definition segment, an event definition segment, a data segment, a service segment, and a notification segment.
As shown in fig. 2, after the user successfully logs in through the APP or the Web, a resource class is created on the RCMS according to a requirement, and the RCMS provides functions of creating, compiling, deploying and releasing for the user. The RCDB is responsible for the storage function of the resource classes, and the resource classes created on the RCMS are deployed and released in the RCDB. RIMS manages resource object instance, and provides the functions of creating, publishing, stopping and invalidating resource object. The RIDB stores resource instance objects, and when the RIRS instantiates, data are read from the database, and the RC is instantiated. The user sends an instruction through the RIMS, the RIMS can call the method of the user, the RIRS finds the corresponding example, and the RIRS responds.
The resource instance execution server also includes a lifecycle mechanism for maintaining the resource instance. And the resource entity accesses the RI through the basic routing component of the server and points to the RI, and if the RI corresponding to the resource entity is not in the server, the resource entity is prompted to acquire the RIRS server address. The system defaults to unidirectional data flow, i.e., resource- > RIRS- > RI. To improve data write processing efficiency, the RIRS provides a resource data write queue: the resource entity submits the data, and the RIRS writes the data into the queue and returns the data immediately; the RIRS acquires data from the data queue through the thread pool and calls corresponding RI search service. In the RIRS, a specific resource object is searched for by a unique address of a resource entity, and the resource object is obtained by the resource entity address, so that a method or service of a resource class can be directly called.
RC is a resource class defined by the user on RCMS. The data structure and the calling method of the resource classes are the same, and the addresses of the resource classes are different from each other. And the RCMS is concurrently released and deployed, and a C/Java-based resource end running library is generated while the RCMS is released and deployed, and can be downloaded by other people.
The user sends an instruction through the resource instance management server, the resource instance management server calls the instance mirror image of the resource, the corresponding resource instance is found from the resource instance operation server, and the resource instance operation server responds. An instance image of a resource is the image of the resource (physical device) at its runtime on the resource instance runtime server.

c) the message dispatcher is responsible for sending messages among the Device, the Server and the Monitor;
d) the message receiver is responsible for receiving messages among the Device, the Server and the Monitor;
e) the data type-JSON serialization library and the deserialization library are responsible for converting communication data into JSON data or converting the JSON data into C # objects, Java objects and C structural bodies.

d) all data types can be automatically converted into JSON data by a data type-JSON serialization deserialization library or the JSON data is converted into the three data types;
e) the data types may be shared in several rc (resource classes) in the form of shared libraries.
Event definition segment:
a) the event is a means for data interaction between the resource entity side and the resource server side and data interaction between the resource monitoring side and the resource server side;
b) the events comprise system-defined events and user-defined events;
c) when developing rc (resource class), event types need to be bound to corresponding processing functions.
Data segment:
a) the data section defines the data content of RC (resource class), such as voltage, rotating speed, temperature and the like;
b) the attribute data defines the basic data content of RC (resource class), such as voltage, rotating speed and the like, the numerical values are determined in operation, namely instantiated in RI (resource instance), and determined by a resource entity end, and the data are defined in the process of creating RC (resource class);
c) static data, which defines the basic information of resource entities and includes creator information, classification, type, available state and other information;
d) and additional information containing static data customized by a user.
Service section:
a) the service segment comprises an instance running at the server end and a method exposed to the resource entity end and the resource monitoring end for running the instance;
b) the method comprises the following steps: method visibility, method name, parameter type, specific implementation of service;
c) because the realization of the server side adopts java development, a user can bind an existing class which accords with the development specification to the service segment;
d) the method of the service segment is operated in an RIRS (resource Instance Runtime Server) resource Instance operating server;
e) the method of the service segment is exposed to the equipment and the monitoring terminal through a predefined interface.
Sixthly, a notification section:
a) the notification segment comprises a processing function of the resource entity end and the resource monitoring end for receiving the message of the server end;
b) the server side stores function interfaces of the notification sections of the resource entity side and the resource monitoring side;
c) the server side calls a function in the interface to trigger a notification event, and the system broadcasts the notification event to each resource entity and the resource monitoring side;
and the message receivers of the resource entity end and the resource monitoring end obtain the events, call a method corresponding to the events and positioned in the notification segment, and process the messages.
And the resource entity accesses the resource instance through the local basic routing component and points to the resource instance, and when the resource instance corresponding to the resource entity is not in the resource entity, the resource entity is prompted to retrieve the address of the resource instance operation server.
The resource entity submits the data, and the resource instance running server writes the resource instance data into the data queue and immediately returns the data; and the resource instance running server acquires data from the data queue through the thread pool and calls corresponding resource instance searching service.
RI is an instantiation of an RC, and the RI structure is shown in FIG. 3.
There are three example mirror types for the RI as an example of the RC:
embodiment mirror image of Resource Instance on Server running on Resource Instance running Server
② example mirror image of Resource Instance on Device running at equipment end
Third, the example mirror image of the Resource Instance on Monitor running at the monitoring end
When a problem occurs in a server, the image on the server can be transplanted to other operable servers.
(4) Realizing resource open to outside through standard interface in model
The method comprises the steps that firstly, front-end equipment resources of the industrial Internet are provided, each equipment has a unique ID-KEY to identify the equipment, the ID-KEY is a KEY which is encrypted by a (DES/RSA) method and can be in one-to-one correspondence with RI (resource instance) of a server side, and if the server side is not registered or an instance is invalidated, data cannot be interacted with the server side.
And the sub code is needed by the embodiment of the resource class to interact data with the server side.
RI (resource instance) mirror image is attribute data instantiation and assignment of RC (resource class); the ID-KEY values which are in one-to-one correspondence with the equipment after the resource instantiation exists; presence status data; identifying whether a connection is currently made; the service segment is presented as an interface Proxy object-Proxy and is responsible for the function of a Proxy server mirror image in the service segment; the notification segment is presented as an unrealized code scaffold for the device side to implement the code here, i.e. secondary development, and receive the event notification sent by the server.
An RI (resource instance) example after an RC (resource class) model is instantiated can be used for realizing secondary development of a user on a service section and a resource management platform through an unrealized code scaffold presented in a notification section.
As shown in fig. 4, if the resource is embodied as a temperature sensor, the user opens the application and acquires the current temperature information first. When a user sends an instruction for changing the temperature to 38 ℃, the temperature sensor is directly connected to the temperature sensor through the network layer, when the temperature of the sensor is adjusted to 38 ℃, the adjusted temperature information is returned, the information is mapped into the data model through the connection service cluster for storage, and the changed temperature information is returned to the user application for display. I.e. it is equivalent that the control end is directly connected to the resource itself, and the parts are highly coupled.
As shown in fig. 5, after the resource management model is added and released, the temperature sensor is connected to the connection server cluster, the connection server stores its own data in the data model and actively maps the data to the model server, the added model server stores the current data, the model server accesses the data update at any time, the application of the application layer, such as APP, accesses the control server and reads the data of the resource from the control server. When the user communicates instructions through the application, such as adjusting the temperature to 38 ℃, the calls through the methods in the model will be displayed to the user at a temperature of 38 ℃, and the instructions are finally communicated by the model through the network layer to the resource itself, which returns the temperature through the sensor and stores. The method reduces the coupling degree of the whole framework, and when a certain part has a problem, the operation of the rest part is not influenced.
(1) Therefore, the method for defining the resource model of the industrial internet platform effectively solves the problem of digital modeling from a resource entity to the industrial internet platform, standardizes the description requirement of the resource model of the industrial internet platform, realizes the unification of resource description modes, reduces the development workload, reduces the coupling degree of resources and a data management module, improves the fault tolerance and manages large-scale industrial internet resources.
(2) The definition of resource objects in the industrial internet platform resource model is more finely controlled, an open resource management method is provided, and the problem that the industrial internet platform resources are closed and not opened is solved.
(3) The definition of the resource object in the industrial internet platform resource model can multiplex the definition of other defined resource objects, can be directly integrated into a new resource object without repeated definition, and is open to the outside.
The description of the resource contains access rights, attributes, methods, services and additional attributes that define the resource. The meanings are as follows:
definition of access rights: the security is the basic requirement of the platform of the internet of things, the access right control is the basic means for ensuring the security, most of the current access right control is specific to users, the security of the system is improved by the right control of the users, but the communication and integration among devices also need the right control, which is more refined right control. The authority control of the resource object mainly comprises the following aspects:
public access rights. The resource instance generated by defining the resource object is globally visible, and all resource instances can access and communicate.
Protected access rights. An object instance that defines the resource object can only be integrated into the resource instance of the resource object or visible by the resource instance that results from inheriting the resource object.
Private: private access rights. The object instance defining the resource object is not accessible by other resource instances, but is only visible by itself or the resource instance integrating the resource object.
And definition of attributes, namely dividing the attributes into two parts, namely basic attributes and integrated attributes of the resource objects.
Basic properties: each resource has its own basic attributes such as factory time, volume, weight, age, manufacturer, warranty period, etc., which may be represented by basic types such as Intege, Float, Double, Long, String, Date, etc.
Integrating attributes: besides basic properties, some resources may be the integration of other resources, for example, the functions of the temperature and humidity sensor may be obtained by integrating the temperature sensor and the humidity sensor, and some properties or functions that are not possessed by a single sensor are obtained by integration. Therefore, the resource objects of the temperature and humidity sensor can be directly integrated with the resource objects of the temperature sensor and the humidity sensor, so that the hierarchical relationship between the resource objects is clear, each resource object can be quickly multiplexed, and the development speed is accelerated.
Definition of the method: the method defined by the resource object is a method for describing basic functions of the resource, such as acquiring real-time data, uploading and issuing data and the like, and when a resource instance is created based on a certain resource object, the resource instance can call the method in the resource object. The definition of the method can also be subject to authority control in view of security.
Public access rights.
Protected access rights.
Private: private access rights.
Definition of service: a series of services can be defined in the resource object, the services are divided into two types, namely system services and custom services, and the resource instances created based on the resource object can call the services to meet the requirements of customers.
System service: a start service, a shut down service, an initialization service, an instantiation service, a data write service, a timer service, etc. of a resource.
Self-defining service: developers can customize services according to own business logic, and can also combine system services to form more complex services meeting customer requirements.
Defining additional attributes: the additional attributes are used for explaining the whole resource object, and the additional attributes comprise the following:
the creator: a person defined for a resource object.
Creating an organization: the organization that defines the resource object includes the members of the organization defining the resource object.
Creation time: the time defined by this resource object.
The basic description of the resource object, which device resource corresponds, the main function, etc. are described.
Example two
The embodiment provides a method for constructing an open resource management model, which comprises the following steps:
creating a resource class on a resource class management server and storing the resource class in a resource class database;
creating a resource instance on a resource instance management server and storing the resource instance in a resource instance database;
the resource instance running server instantiates, reads the resource class from the local resource class database, and instantiates the resource class;
the user sends an instruction through the resource instance management server, the resource instance management server calls a self method, the corresponding resource instance is found from the resource instance operation server, and the resource instance operation server responds.
And the resource entity accesses the resource instance through the local basic routing component and points to the resource instance, and when the resource instance corresponding to the resource entity is not in the resource entity, the resource entity is prompted to retrieve the address of the resource instance operation server.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
