Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic structural diagram of a node interaction system is provided for the present invention.
The node interactive system comprises a main Control node (Control Computer) and n Remote nodes (Remote notes), and AS5643 bus communication is adopted between the main Control node and the plurality of Remote nodes. The main control node and the plurality of remote nodes adopt a chain ring network structure.
The diagram shows a master node and n remote nodes, where n is a positive integer. The number of remote nodes may depend on the network topology of the actual node interaction system, which is not limited.
Taking an airplane avionics network as an example, the master control node may be an airplane management computer, and the remote nodes may include a sensor module, a power management module, an inertial navigation module, and the like.
The master node may integrate one or more applications, some of which require data interaction with remote nodes via AS5643 bus. In order to facilitate the development of applications by users, the invention provides a publish-subscribe mechanism based on an AS5643 bus.
The application in the main control node in the publish-subscribe mechanism can publish application data to the AS5643 bus, and the application in the main control node can also subscribe the application data published by the remote node from the AS5643 bus, so that data interaction between the main control node and the remote node is realized.
The publish-subscribe mechanism can realize the separation of upper-layer application and bottom-layer communication protocols, so AS to shield the AS5643 bus bottom-layer communication protocol for the upper-layer application and shield the upper-layer application characteristic for the AS5643 bus, thereby realizing the dual purposes of effectively utilizing the reliability and high-speed bandwidth characteristic of the AS5643 bus and facilitating the development and application of users.
The pre-configuration process of the present invention is described below. Referring to fig. 2, the method comprises the following steps:
step S201: the master control node acquires an interface control document of the node interaction system.
Each node in the node interactive system may include a plurality of interfaces (software interfaces or hardware interfaces), and the plurality of interfaces may be divided into two types of transmission types and reception types. That is, each node may include one or more publish data interfaces of a send type and one or more subscribe data interfaces of a receive type.
After the node interaction system is built by adopting the AS5643 bus, an Interface Control Document (ICD) of the node interaction system can be obtained. The interface control document comprises interface configuration information corresponding to each interface of each node in the node interaction system.
Taking interface configuration information corresponding to an interface of a node as an example, the interface configuration information is explained as follows:
the interface configuration information comprises an interface name, a data type for transmitting application data, message configuration of a node to which the interface belongs, and node identifiers of nodes of both sides connected by the interface.
The data type in the interface configuration information may include an integer type, a boolean type, a floating point type, or a structure type.
The message configuration in the interface configuration information comprises: a start of frame packet configuration, an asynchronous stream packet configuration, and a periodic configuration.
Message configuration is the configuration that the message needs to satisfy in the AS5643 protocol, and most of communication in the AS5643 protocol is realized by using asynchronous stream packets, so the asynchronous stream packet configuration needs to be set.
In order to maintain global synchronization among all nodes on a bus in the AS5643 protocol, the AS5643 protocol specifies that a master node sends a frame start packet on the bus at a fixed frame frequency to notify all nodes on the bus of the start of a new frame, and provides a global synchronization source for the nodes in the bus, so that the configuration of the frame start packet needs to be set.
The node identifiers in the interface configuration information include node identifiers of a sending node and a receiving node which are connected by the interface. One interface is used for connecting the main control node and the remote node, wherein one node is a sending node, and the other node is a receiving node.
Step S202: and the master control node determines the attribute set of each interface based on the configuration information of each interface.
For each interface configuration information, the processing procedure of the master node is consistent, so the procedure of determining the attribute set is described by taking one interface configuration information as an example. The attribute set may include the following attributes, each described below.
(1) And the master control node allocates a unique identifier for the interface.
In order to distinguish the interfaces of the nodes, each interface is assigned a unique identifier.
(2) The main control node constructs an Application Programming Interface (API) for the Interface based on the Interface name and the data type in the Interface configuration information.
In order to shield the bottom layer communication protocol from the upper layer application, an application program interface is set for the interface, so that the upper layer application only needs to face the application program interface, thereby shielding the bottom layer communication protocol.
S1: the master control node constructs the name of an application program interface containing the interface name based on the interface name in the interface configuration information;
s2: the main control node constructs parameters of an application program interface based on the data type in the interface configuration information;
s3: and building the application program interface comprising the name of the application program interface and the parameters of the application program interface.
Taking the interface configuration information of a fuel AS an example, the interface name is FuelOil, the data type is structure type, and the name of the constructed application program interface may be "AS 5643 SubsribeFuelOil", and the parameter of the constructed application program interface is structure AS5643 FuelOil.
Then, the application program interface for fuel: named AS AS5643subsribeFuelOil and the parameter is Struct AS5643 FuelOil.
It should be noted that the application program interface name includes an interface name, and is used for indicating that the application program interface corresponds to the interface.
(3) And constructing a corresponding relation between the interface identification and the application program interface, and constructing a corresponding relation between the interface identification and the message configuration in the interface configuration information.
| Interface | Interface identification | API | Message configuration |
| Interface 1 | Interface identifier 1 | API 1 | Message configuration 1 |
| Interface 2 | Interface identification 2 | API 2 | Message configuration 2 |
| …… | …… | …… | …… |
For an interface, the interface identifier, the application program interface, and the corresponding relationship between the interface identifier and the application program interface are all interface attributes, and a plurality of attributes form an attribute set of the interface.
Step S203: the master control node sends the interface configuration information and the attribute set of each interface to the node to which the interface belongs, so that the node stores the interface configuration information and the attribute set.
Taking a node as an example, the node comprises an interface 1 and an interface 2. The interface configuration information 1 and the attribute set 1 corresponding to the interface 1 of the node are stored in the node, and the interface configuration information 2 and the attribute set 2 corresponding to the interface 2 are also stored in the node.
The method is suitable for data interaction between the remote node and the main control node, and under the condition that the main control node issues data to the remote node, the main control node is a sending node, and the remote node is a receiving node. And under the condition that the remote node issues data to the main control node, the remote node is a sending node, and the main control node is a receiving node.
The following describes in detail a data interaction process between a sending node and a receiving node, taking the sending node and the receiving node as an example.
The invention provides a node interaction method, which can comprise the following steps as shown in figure 3:
step S301: the upper layer application in the sending node determines the application data information.
And the upper layer application in the sending node determines the application data and the release interface identifier needed by the application data and generates application data information comprising the application data and the release interface identifier.
For example, when a fuel quantity control application in the master control node needs to send fuel data to a remote engine node through a fuel data publishing interface, it may be determined that the publishing interface identifier is the identifier of the fuel data publishing interface.
The sending node generates application data information containing receiving node identification, issuing interface identification and application data. The receiving node identifier may be a name or an IP address of the receiving node, and the specific implementation may be determined according to an actual scenario, which is not limited in the present invention.
Step S302: and calling a preset application program interface corresponding to the release interface identifier by the upper application in the sending node.
The sending node is stored with a preset application program interface corresponding to the issuing interface identifier in advance and the corresponding relation between the issuing interface identifier and the preset application program interface, so that the sending node can inquire and obtain the preset application program interface corresponding to the issuing interface identifier.
Step S303: and the upper layer application in the sending node utilizes a preset application program interface to issue application data information to the global data area.
Step S304: and the core data layer in the sending node acquires the application data in the global data area.
Under the condition that the upper layer application does not need to face the bottom layer communication protocol, the core data layer realizes the bottom layer communication protocol, so the core data layer obtains the application data from the global data area.
Step S305: and inquiring message configuration and routing configuration corresponding to the issuing interface identification by a core data layer in the sending node.
Because the message configuration of the publishing interface identifier is stored in advance and the corresponding relation between the publishing interface identifier and the message configuration is stored, the core data layer can inquire and obtain the message configuration corresponding to the publishing interface identifier.
Since the interface configuration information for issuing the interface identifier is stored in advance, the interface configuration information includes the node identifier, and the node identifier includes the address of the receiving node. The core data layer in the sending node may determine the routing configuration of the receiving node based on the receiving node address.
Step S306: the core data layer in the sending node converts the application data into target data conforming to the message configuration.
After determining the message configuration, the core data layer in the sending node may convert the application data so that the application data conforms to the message configuration so AS to be suitable for the underlying communication protocol of the AS5643 bus.
Step S307: the core data layer in the sending node sends the target data to the bus according to the routing configuration, so that the bus forwards the target data to the receiving node based on the routing configuration.
The core data layer of the sending node may send the destination data and the routing configuration to the bus for the bus to send the destination data to the receiving node based on the routing configuration. The bus routing process is well-established and will not be described in detail herein.
Step S308: and the core data layer in the receiving node receives the target data transmitted by the bus.
Step S309: and the core data layer of the receiving node determines a subscription interface identifier corresponding to the publishing interface identifier and inquires the message configuration corresponding to the subscription interface identifier.
Since the publishing interface identifier and the subscribing interface identifier have a corresponding relationship, for example, a corresponding relationship exists between the fuel publishing interface and the fuel receiving interface, the subscribing interface identifier corresponding to the publishing interface identifier can be determined.
The receiving node stores the message configuration corresponding to the subscription interface identifier and the corresponding relationship between the subscription interface identifier and the message configuration, so that the message configuration corresponding to the subscription interface identifier can be obtained after inquiry.
Step S310: and the core data layer of the receiving node analyzes the target data by using the message configuration to acquire the application data.
The message configuration of the publishing interface is associated with the message configuration of the subscribing interface, so that the message configuration corresponding to the subscribing interface identifier can be used for analyzing the target data, thereby obtaining the application data of the stripped AS5643 bus bottom layer communication protocol.
Step S311: and the core data layer of the receiving node stores the application data to the global data area and constructs the incidence relation between the application data and the subscription interface identifier.
The receiving node stores the application data to the global data area and builds the incidence relation between the application data and the subscription interface so that the receiving node can acquire the application data from the global data area.
Step S312: and determining the subscription interface identifier by the upper layer application of the receiving node under the condition that the application data needs to be subscribed.
And the generation application of the receiving node determines the subscription data interface identifier under the condition that the subscription application data needs to be acquired.
Step S313: and the upper layer application of the receiving node calls a preset application program interface corresponding to the subscription interface identifier.
Step S314: the upper layer of the receiving node is applied to the global data area to obtain the application data corresponding to the subscription interface identifier.
