Problems solved by technology

Zhao Zhengwei's "Research and Application of Component-Based Distributed Virtual Test Software" analyzed the advantages of building distributed virtual test software based on ACE / TAO, but did not involve the specific technical approach of implementation; the middleware implementation method introduced can provide real-time communication services , scheduling management service, time synchronization service, and program configuration management service, but its service components are implemented using VMIC, which does not have interoperability and cross-platform features

Embodiment Construction

[0030]Before describing the specific implementation of the present invention, the technical terms used in the present invention are explained: ACE (Adaptive Communication Environment, Adaptive Communication Environment) encapsulates the communication, scheduling, and concurrent services of the operating system with an excellent design pattern, supports A variety of operating systems, including Windows, UNIX, Linux, VxWorks. TAO is an ORB implemented based on ACE and following the real-time CORBA standard.

[0031] like figure 1 As shown, the middleware system described in the present invention is implemented based on the open source project ACE / TAO.

[0032] The present invention builds four modules on the basis of ACE / TAO, including a time advancement module, an operation management module, an interaction management module, and a callback management module, and encapsulates the functions of the four modules into an easy-to-use application program interface API for testers to...

Abstract

A virtual test middleware system based on The ACE ORB (TAO) comprises a time boosting module, an operation management module, an interactive management module, a callback management module and an application program interface (API), the time boosting module, the operation management module, the interactive management module and the callback management module transmit data through an event channel, and the event channel is an event channel object in an object request broker (ORB) of the TAO. By means of the virtual test middleware system based on the TAO, the real-time communication and scheduling between test objects and test resources in the virtual test system execution period are achieved, the virtual test application logic and communication decoupling are achieved, and thereby the virtual test system which is developed based on the middleware has the characteristics of interoperability, cross-platform and the like.

Description

technical field [0001] The invention relates to a middleware system for virtual test communication, in particular to building a virtual test middleware system based on TAO, and belongs to the technical field of virtual test. Background technique [0002] With the constraints of political, economic and other factors and the needs of military development, it is very important to carry out virtual experiments in the field of defense industry. Virtual test is a new test technology developed for the performance test, technical index assessment and comprehensive effectiveness evaluation of weaponry and equipment by using computer modeling and simulation technology combined with test technology, communication technology and computer network technology. Virtual experiment is developing towards the direction of "combination of virtual and real" and "integration". The virtual test middleware can well solve the interconnection of test objects and test resources during the test, and re...
