It is described below and of the invention is pre-configured with process.Referring to fig. 2, comprising the following steps:
Step S201: the interface control document of main controlled node acquisition node interactive system.
Each node may include multiple interfaces (software interface or hardware interface) multiple interfaces in node interactive system
Two types transmission types can be divided into and receive type.That is, each node may include one or more transmission types
Data-interface is issued, and, one or more receives the subscription data-interface of type.
After building node interactive system using AS5643 bus, the interface control document of available node interactive system
(Interface Control Document, ICD).Interface control document includes each of each node in node interactive system
Interface each interface configuration information correspondingly.
By taking the corresponding interface configuration information of the interface of a node as an example, interface configuration information is illustrated:

S3: the application programming interfaces comprising the title of application programming interfaces and the parameter of application programming interfaces are set up.
By taking the interface configuration information of a fuel oil as an example, interface name FuelOil, data type is structural body type,
The application programming interfaces title then constructed can be that parameter of " AS5643SubsribeFuelOil " building application programming interfaces be
Structural body Struct AS5643FuelOil.
So, the corresponding application programming interfaces of fuel oil: entitled AS5643SubsribeFuelOil, parameter Struct
AS5643FuelOil。
It should be pointed out that application programming interfaces title includes interface name, it is intended that in order to indicate this using journey
Sequence interface is corresponding with the interface.
(3) corresponding relationship for constructing interface identifier and application programming interfaces, constructs in interface identifier and interface configuration information
The corresponding relationship of message arrangement.
| Interface | Interface identifier | API | Message arrangement |
| Interface 1 | Interface identifier 1 | API 1 | Message arrangement 1 |
| Interface 2 | Interface identifier 2 | API 2 | Message arrangement 2 |
| …… | …… | …… | …… |
Wherein, for an interface, interface identifier, application programming interfaces, interface identifier and application programming interfaces
The corresponding relationship of corresponding relationship, interface identifier and message arrangement is interface attributes, and multiple attributes form the property set of the interface.
Step S203: main controlled node sends node belonging to the interface configuration information and property set to interface of each interface,
For node memory interface configuration information and property set.
By taking a node as an example, which includes interface 1 and interface 2.Then the corresponding interface of the interface of the node 1 is configured
Information 1 and property set 1 are stored into the node, and the corresponding interface configuration information 2 of interface 2 and property set 2 are also stored to the section
Point in.
The present invention is suitable for data interaction between remote node and main controlled node, issues data to long-range in main controlled node

Configuration sends target data to receiving node.It has been mature technology about bus routing procedure, details are not described herein.
Step S308: core data layer receives the target data of bus transfer in receiving node.
Step S309: the core data layer of receiving node determines subscribing interface mark corresponding with issuing interface mark, and
Inquire message arrangement corresponding with subscribing interface mark.
Since issuing interface mark and subscribing interface mark have corresponding relationship, for example, fuel oil issuing interface and combustion
There is corresponding relationship, it is possible to determine subscribing interface mark corresponding with issuing interface mark between oily receiving interface.
Receiving node is stored with subscribing interface and identifies corresponding message arrangement, and, subscribing interface mark and message arrangement
Between corresponding relationship, it is possible to corresponding with subscribing interface mark message arrangement is obtained after inquiry.
Step S310: the core data layer of receiving node is obtained using message arrangement parsing target data and applies data.
The message arrangement of issuing interface and the message arrangement of subscribing interface are associated, so utilizing subscribing interface mark pair
The message arrangement answered can be used for parsing target data, to obtain the application number of removing AS5643 bus basic communication protocol
According to.
Step S311: the core data floor storage of receiving node is constructed using data to global data area using data
With the incidence relation of subscribing interface mark.
Receiving node storage constructs the incidence relation using data and subscribing interface using data to global data area,
Data are applied so that receiving node is obtained from global data area.
Step S312: the upper layer application of receiving node determines subscribing interface mark in the case where that need to subscribe to using data.
The generation of receiving node is applied in the case where that need to obtain subscription using data, is determined and is subscribed to data interface identifier.
Step S313: the upper layer application of receiving node calls subscribing interface to identify corresponding default application programming interfaces.
Step S314: the upper layer application of receiving node obtains application number corresponding with subscribing interface mark in global data area
