Detailed Description
The invention is further described with reference to the following figures and embodiments.
With reference to fig. 1-2, in the heterogeneous simulation system implementing interconnection by building data bridging software according to the present embodiment, a bridging software generation tool is built according to interconnection of heterogeneous training simulation systems, and a bridging operation management tool is built according to interconnection application processes of heterogeneous test training systems;
the bridging software generation tool comprises a data configuration module and a code generation module; the data configuration module is responsible for collecting published order data input by a user and data pairing relation and generating a gateway interaction data description table; and the code generation module is responsible for analyzing the gateway interaction data description table and generating a gateway code and a related configuration file.
In a specific embodiment, the data configuration module: and providing a visual data configuration module according to the information interaction content, the data corresponding relation and the requirement of a synchronous mode among the heterogeneous interconnected test training systems. The data configuration mainly comprises the steps that a data description file and an FED file are read in, and a user selects a corresponding published order data type according to data interaction requirements, forms a corresponding relation of published order data and generates a bridging interaction data description file. The code generation module has the main functions of reading in the gateway interactive data description file, generating a module code generation frame, analyzing the obtained data such as the publish/order relationship and the like according to XML, completing the code frame, and finally generating a gateway module code.
The bridging operation management tool comprises a portal management module, an agent bridging management module and a customized API module, centralized management is carried out on a typical heterogeneous interconnected agent gateway through a portal, and componentization prefabrication is carried out for heterogeneous interconnected data conversion and application.
The portal management module: the system comprises modules of application starting, connection management, heterogeneous interconnection conversion objects, information management and the like, and has the main functions of finishing conversion gateway configuration, starting parameter configuration, conversion simulation object/interactive object flexible viewing (filtering rapid viewing, object state display, statistical view viewing, object/interactive real-time monitoring and the like), portal exit and the like based on a visual window.
The agent bridging management module: the proxy gateway is a bridging conversion tool between HLA, DDS, TENA, DIS and other communication protocol application cluster test environments, typical system objects such as HLA, DDS, TENA, DIS and the like and interactive data packet mapping are realized, proxy gateway components are prefabricated, unified management is performed through portal management, toolized components are provided for heterogeneous system tests, and heterogeneous interconnection operation and heterogeneous interconnection gateway management are facilitated.
The proxy gateway component is internally provided with a plurality of universal converters, each converter is responsible for a specific object or interaction class, the universal converters filter FOM related contents, and a user is supported to use a uniform FOM table to create a customized RTI-heterogeneous system bridge, so that heterogeneous system connection is realized. Wherein the proxy gateway component is initially effectively an empty translation component, does not undertake any protocol translation, and simply copies each attribute or parameter byte-by-byte from portal to portal and publishes it to the network. Figure 3 illustrates the working principle of the proxy gateway component.
There is no subway name converter in all federal in fig. 3. The leftmost federation 1 sends "subway" information, and the proxy gateway component need only send the string "subway" to the shared data memory region of the interaction bus. The middle federation 2 reads from the portal the string "subway", which has application value to federation 2, which is the same string sent by federation 1, so it also sends "subway" messages. The rightmost federation 3 does not configure a universal converter, so federation 3 ignores the string. Thus, when the simulated training system contains an interaction without a translation, a generic translation may be added to the proxy gateway component. If two or more systems use similar data structures but the underlying communication components are different, the proxy gateway component will create a set of generic translation translators for all objects and interactions in the FOM. The direct application of the gateway when the various heterogeneous interconnection systems are interconnected is realized, the data standard and the bottom layer communication mode are unified, and the problems that the data protocols of the various heterogeneous systems are difficult to be consistent, and the development of the gateway needs repeated bottom layer communication development are solved.
Customizing the API module: the extended custom API has two main components, a portal API and a proxy API. The proxy API allows the user to create various communication protocol conversion proxies that fit into the "gateway," supporting the user to extend the proxies provided by the "gateway. The portal API allows the agent to send messages to the portal and receive updates from the portal.
