Communication method for flight simulator

Abstract

The invention provides a communication method for a flight simulator. The method comprises a plurality of computers connected with a network switch by adopting an ether network cable through a network card, and a central computer provided with a plurality of network cards. The central procedure executed in the central computer comprises an external configuration analysis module, a data receiving module, a data sending module, a data integration module and a data monitoring module. An external configuration file comprises a data package configuration file and a communication route configuration file. Each communication computer only sends data to the central computer and receives the data from the central computer. The communication route of data is determined by the central computer according to the external configuration file, communication decoupling between simulated programs of the computers is achieved, and the simulated programs can be reused easily; the central computer reduces communication data redundancy through data package integration, data jam is eliminated, and the communication efficiency is improved; communication between simulation nodes is simplified and standardized, and the expandability and the transportability of the system can be improved.

Description

technical field [0001] The invention relates to the technical field of simulation communication, in particular to a flight simulator communication method. Background technique [0002] In a large-scale flight simulator, multiple computers need to cooperate to complete the simulation task. It is one of the key issues that multiple computers run simulation applications to communicate with each other in a flight simulator. At present, the communication mode of computers disclosed by flight simulators is usually "point-to-point" communication, that is, each computer determines its communication partner according to the simulation application program and completes the communication. If there are n simulation applications in the system that need to communicate, in extreme cases, there need to be n(n-1) logical communication links in the system. The shortcomings of this communication method in the flight simulator are: there are many communication links, data congestion, waste of...

Problems solved by technology

The shortcomings of this communication method in the flight simulator are: there are many communication links, data congestion, waste of network bandwidth, and the flight simulator causes communication efficiency to drop; the simulation application programs of the computer are tightly coupled, and each simulation application program is It is necessary to know the existence of other simulation applications that communicate with it; the communication method is not standardized, and when the simulation application that needs to communicate is added to the system, it may lead to the modification of the communication code of the existing simulation application; the dispersion of communication data causes Communication data monitoring is difficult, which is not convenient for debugging during system development and status monitoring during system operation
