[0003] However, the application interface of the DCPS layer is a general design. In actual use, the call stack is very complex, and it is necessary to create the entity objects of the data distribution service layer by layer and set the quality of service (QoS) attribute values ​​accordingly. Taking the publication of data on a certain topic as an example, it is necessary to call the interface of the DCPS layer and create five objects, DomainParticipantFactory, DomainParticipant, Publisher,DataWriter, and Topic, in sequence, and set the QoS attribute values ​​of five levels, namely DomainParticipantFactoryQos, DomainParticipantQos, PublisherQos, DataWriterQos, and TopicQos, for the five objects respectively.

[0027] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In order to solve the technical problem that the application interface of the DCPS layer of the data distribution service in the embedded system is complex to use and difficult to develop and debug, this embodiment proposes a processing method for the data distribution service. Figure 1 As shown, the method includes:

[0029] S101, obtaining system encoding parameters of the embedded system.

[0030] System encoding parameters refer to hard-coded parameters in the embedded system, such as the embedded system's entity object configuration (such as Topic / Writer / Reader configuration) and entity service quality attribute values ​​(QoS attributes), maximum number of instances, maximum number of samples, DataWriter's heartbeat period, etc.

[0031] Taking the configuration of some entity objects as an example, dw_qos.protocol.rtps_object_id = 100, which means setting the rtps object id of DataWriter; dw_qos.reliability.kind = DDS_RELIABLE_RELIABILITY_QOS; which means setting the reliabilityQos type of DataWriter. These specific assignments belong to the above-mentioned system coding parameters.

[0032] S102: Determine configuration parameters related to the data distribution service from system coding parameters.

[0033] Among them, the configuration parameters include the configuration parameters of the first entity object, and the first entity object encapsulates multiple second entity objects of the DCPS layer. First of all, the DCPS layer is the core layer of the DDS service, which is data-centric and is used to provide the functions of publishing and subscribing to data, so that publishers can publish their own data, subscribers can subscribe to the data of interest, and establish a maintenance-free and fast data channel. The second entity object here is a stateful DDS communication object in the traditional DCPS layer, including DomainParticipant, Publisher, Subscriber, Topic, DataWriter and DataReader. The first entity object is obtained by encapsulating multiple second entity objects. For example, it can be encapsulated into a first context entity object, a first publishing entity object and a first subscription entity object according to the type.

[0034] S103, processing the configuration parameters related to the data distribution service to obtain global variable information of the configuration data used by the DLRL layer.

[0035] The DLRL (Data-Local Reconstruction layer) is a local data reconstruction layer and an optional layer of the DDS service. It is built between the DCPS and the application layer and encapsulates the services provided by the DCPS layer, allowing the application layer to quickly access data and simplifying the programming work of the application layer.

[0036] S104, configuring the interface function of the data distribution service using the global variable information.

[0037] The interface function is used to process data communication corresponding to the data distribution service in the embedded system. That is, by encapsulating the second entity interface and designing the interface function at the DLRL layer, an application interface at the DLRL layer is provided for developers.

[0038] In this embodiment, the system coding parameters of the embedded system are first obtained, and the configuration parameters related to the data distribution service are determined in the system coding parameters. Among them, the configuration parameters include the configuration parameters of the first entity object, and the first entity object encapsulates multiple second entity objects of the DCPS layer. Then the configuration parameters are processed to obtain the global variable information of the configuration data used by the DLRL layer, and the interface function of the data distribution service is configured using the global variable information. In order to facilitate the embedded platform application layer code to use the data distribution service for data communication, by encapsulating the entity creation, initialization and data publishing and subscription interface of the DCPS at the DLRL layer, and configuring the interface function according to the determined configuration parameters, a set of streamlined calling interfaces is provided to developers, thereby facilitating developers to use the data distribution service for communication. The existing DDS initialization process is solved. The technical problems of being too complicated to start and create, and the parameter configuration and steps are numerous, and the user experience is improved. In addition, the technical solution provided in this embodiment also simplifies the development process of using DDS for communication in embedded devices, making application developers faster and more efficient when using DDS development, and easy to debug the system.

[0039] In addition, since many embedded system environments lack file systems and other limitations and cannot read configuration files, many of these creation and configuration processes need to be hard-coded in the user-level logic code, increasing the complexity of embedded system development and debugging. Moreover, most of the embedded devices in the Internet of Things network act as edge nodes and their functions are relatively static. Due to system resources (system memory, etc.) and functional limitations, they will only contain one DomainParticipant, and all entity objects will be created at one time when the system is initialized, and their associated QoS attribute values ​​will also be solidified in the program and do not need to be dynamically modified. Most DCPS dynamic creation interfaces are not used in embedded devices, resulting in a waste of resources. However, the technical solution provided in this embodiment uses a streamlined DLRL layer interface design, which does not require reading related configurations in the user-level logic code, nor does it require creating multiple dynamic interfaces, thereby saving this part of wasted resources and making application developers faster and more efficient when using DDS development.

[0040] Optionally, determining configuration parameters related to the data distribution service from the system coding parameters includes: processing the system coding parameters to obtain a configuration file; and reading the configuration parameters related to the data distribution service from the configuration file.

[0041] In this embodiment, before obtaining the configuration parameters, the system coding parameters need to be processed to obtain a configuration file, and then the configuration parameters related to the data distribution service are read from the configuration file, so as to facilitate the subsequent configuration of the interface function and the encapsulation of the entity.

[0042] Further, the system encoding parameters are processed to obtain a configuration file, including: converting the system encoding parameters into a configuration file in a preset format;

[0043] Reading configuration parameters related to the data distribution service from the configuration file includes: using a configuration code generation tool to read the configuration parameters related to the data distribution service from a configuration file in a preset format.

[0044] In this embodiment, the steps of obtaining configuration parameters are further described. First, the system coding parameters need to be converted into a configuration file in a preset format, where the preset format may include an Extensible Markup Language (XML) format or a JavaScript Object Notation (JSON) format. Then, a configuration code generation tool is used to read the configuration parameters related to the data distribution service from the configuration file that has been converted into XML or JSON format. By converting the format of the system coding parameters and reading them using the configuration code generation tool, the difficulty of obtaining configuration parameters from a large number of system coding parameters is simplified, thereby facilitating the subsequent configuration of interface functions and the encapsulation of entities.

[0045] Optionally, filling the configuration parameters related to the data distribution service into the corresponding configuration code template to generate instantiated code information includes: using a configuration code generation tool to fill the read configuration parameters related to the data distribution service into the corresponding configuration code template to generate code information. The code information includes global variable information.

[0046] In this embodiment, the configuration code template may use the jinja2 template engine to generate instantiated code information, wherein the code information includes global variable information for designing the interface function, thereby realizing the subsequent configuration of the interface function.

[0047] Furthermore, configuring the interface function of the data distribution service using the global variable information includes: configuring the interface function of the data distribution service using code information containing the global variable information.

[0048] In this embodiment, using global variable information to configure the interface function of the data distribution service specifically uses code information containing global variable information to configure the interface function of the data distribution service, thereby realizing the configuration of the interface function.

[0049] Optionally, the system coding parameters include: system coding parameters of the embedded system, entity object configuration and entity service quality attribute values; using a configuration code generation tool, the configuration parameters related to the data distribution service read are filled into a corresponding configuration code template to generate instantiated code information, including: using the configuration code generation tool to determine a target configuration code template of a type corresponding to the configuration parameters, and filling the configuration parameters into the target configuration code template to generate code information.

[0050] In this embodiment, the system coding parameters include hard-coded parameters such as system resource parameters, Topic / Writer / Reader configuration and Qos attributes. Using the configuration code generation tool, the configuration parameters related to the data distribution service are filled into the corresponding configuration code template to generate instantiated code information. Specifically, the configuration code generation tool is used to determine the target configuration code template of the corresponding type of the configuration parameters. Then, the configuration parameters are filled into the target configuration code template to generate code information. The efficiency of the configuration code generation tool in obtaining configuration parameters is improved.

[0051] Optionally, the first entity object includes: a first context entity object, a first publishing entity object and a first subscription entity object; the first context entity object encapsulates multiple second context entity objects related to the publishing and subscription operations of the DCPS layer; the first publishing entity object encapsulates multiple second publishing entity objects related to data publishing of the DCPS layer; the first subscription entity object encapsulates multiple second subscription entity objects related to data publishing of the DCPS layer.

[0052] In this embodiment, the first entity object may include a first context entity object Bus context, a first publishing entity object Bus writer, and a first subscription entity object Bus reader, and may also include topic / instance of each topic and the corresponding data type Type. Among them, the first context entity object Bus context encapsulates multiple second context entity objects related to the publishing and subscription operations of the DCPS layer, such as DomainParticipantFactory, DomainParticipant, DomainParticipantQos, etc. The above objects in each application are unique. The first subscription entity object Bus reader encapsulates Subscriber, SubscriberQos, DataReader, DataReaderQos, DataReaderListener, and the Topic and type information corresponding to DataReader, and can receive data subscriptions according to the callback passed in by the user. The first publishing entity object Bus writer encapsulates Publisher, PublisherQos, DataWriter, DataWriterQos, DataWriterListener, and the Topic and Type information corresponding to DataWriter, and can publish data through the publish interface. Entity encapsulation makes the functions more centralized, thereby facilitating developers to communicate using data distribution services.

[0053] like Figure 2 FIG. 1 shows another method for processing data distribution services provided by this embodiment, and describes the steps of obtaining code information containing global variable information. The method includes:

[0054] S201, obtaining system encoding parameters of the embedded system.

[0055] S202, converting the system encoding parameters into a configuration file in a preset format.

[0056] S203: Using a configuration code generation tool, read configuration parameters related to the data distribution service from a configuration file in a preset format.

[0057] S204, filling the read configuration parameters related to the data distribution service into the corresponding configuration code template to generate instantiated code information.

[0058] S205: Use the code information including the global variable information to configure the interface function of the data distribution service.

[0059] In this embodiment, the system coding parameters are first converted into a configuration file in a preset format. The system coding parameters here include hard-coded parameters such as system resource parameters, Topic / Writer / Reader configuration and Qos attributes. The preset format can generally be selected in XML format or JSON format, so that the configuration code generation tool can be used to read the configuration parameters related to the data distribution service from the configuration file in the preset format. Then, the read configuration parameters related to the data distribution service are filled in the corresponding configuration code template to generate instantiated code information. Finally, the interface function of the data distribution service can be configured according to the code information containing global variable information. Among them, the principles of the configuration code generation tool and the jinja2 template engine are as follows Figure 3 As shown. By encapsulating the entity creation, initialization and data publishing and subscription interface of DCPS in the DLRL layer, and configuring the interface function according to the determined configuration parameters, a set of streamlined calling interfaces is provided to developers, thereby facilitating developers to use data distribution services for communication. The technical problems of the existing DDS initialization process being too complicated to start and create, and having numerous parameter configurations and steps are solved, thereby improving the user experience. In addition, the technical solution provided in this embodiment also simplifies the development process of using DDS for communication in embedded devices, making it faster and more efficient for application developers to develop using DDS, and easier to debug the system.

[0060] Furthermore, the present embodiment also exemplarily provides encapsulation types of some interfaces and corresponding interface function configuration methods. Of course, the encapsulation type and configuration method can also be determined by the user according to the actual application scenario.

[0061] Package types may include:

[0062] Context encapsulation entity bus_context_t: Encapsulates the context entities related to the publishing and subscription operations in the DCPS Entity, and encapsulates the common properties such as DomainParticipantFactory, DomainParticipant, DomainParticipantQos, service discovery configuration, network interface configuration, etc. into the bus_context_t object for life cycle management.

[0063] Publishing encapsulation entity bus_writer_t: Encapsulates the entity that publishes data in DCPS Entity, and encapsulates DataWriter, DataWriterQos, DataWriterListener and the Topic / Type information they depend on.

[0064] Subscription encapsulation entity bus_reader_t: encapsulates the entity for data subscription in DCPS Entity, and encapsulates DataReader, DataReaderQos, DataReaderListener and its dependent Topic / Type information.

[0065] Interface function configuration may include:

[0066] bus_register_profile loads system configuration: This interface function is used to load the configuration data structure in the configuration code (generated by the configuration code generation tool busconfgen). The process is as follows:

[0067] Load network interface configuration; load service discovery configuration; load domain_id; load topic related configuration; load datawriter, datareader related configuration; load Qos configuration.

[0068] bus_register_reader_callback registers subscription data callback: This interface is used to register the user's callback function for processing subscription data. The callback function will be triggered when the data arrives. The process is: mount the user callback function pointer to DataReaderListener. When the RTPS layer receives the data, it will trigger the user's registered callback function through DataReaderListener to perform business logic processing on the data.

[0069] bus_init system initialization: This interface is used to initialize all components of the DDS system. The process is as follows: initialize Writer Histroy and Reader History modules; initialize Udp interface; initialize service discovery module; create entities at the DomainParticipant, publisher, and subscriber levels, initialize all Topics, and register corresponding Types; create all bus_writers according to the configuration, encapsulate DataWriter, DataWriterQos, and DataWriterListener in bus_writer, and establish a hash mapping table from topic to bus_writer; create all bus_readers according to the configuration, encapsulate DataReader, DataReaderQos, and DataReaderListener in bus_reader, and establish a hash mapping table from topic to bus_reader; Enable all DDSEntity, and the service startup is complete.

[0070] bus_publish publishes data: This interface is used to publish data sample data created by the user to a specific topic. The process is as follows: According to the topic in the parameter, the corresponding DataWriter is found from the hash mapping table from topic to bus_writer, and the write function interface of the DCPS layer DataWriter is called to publish the data.

[0071] Figure 4 The following is an application example after encapsulating entities according to the above method, where mvbs1 and mvbs2 can be regarded as two nodes publishing and subscribing to data. Both nodes include encapsulated entities such as bus_reader and bus_writer, and interact through the subject Topic and data type data type. Figure 5 The process of data publishing and subscription using the encapsulated interface bus api is shown. The data subscription process includes calling bus_register_profile to load the global configuration (the configuration code is generated by the configuration code generation tool busconfgen), then calling bus_register_reader_callback to register the callback function for processing when the data arrives, and finally calling bus_init to initialize the DDS system. The data publishing process includes calling bus_register_profile to load the global configuration, then calling bus_init to initialize the DDS system, and finally creating a data sample and calling the bus_writer_publish interface to publish the data.
