A reconfigurable distributed real-time simulation method based on rtx-hla-reflective memory card

Abstract

The invention relates to the field of computer application technology and computer networks, in particular to a method for reconfigurable distributed real-time simulation based on an RTX-HLA reflection storage card. The method comprises the following steps that a real-time sub system is constructed through a real-time RTX process and a non-real-time Win32 process together; a non-real-time sub system is constructed through the non-real-time Win32 process; more than two real-time sub systems are connected to a reflection storage exchanger through a reflection storage network, more than two non-real-time sub systems are connected to an Ethernet exchanger through the HLA network, and the reflection storage exchanger and the Ethernet exchanger are connected through the Ethernet so that simulation systems can be formed; more than two simulation systems are mutually connected through the reflection storage network so that a simulation system platform can be formed. The method can satisfy the requirements for the real-time performance and the determinacy of the distributed real-time simulation systems and is simple in program, low in cost and high in reliability.

Description

technical field [0001] The invention relates to the fields of computer application technology and computer network, in particular to a reconfigurable distributed real-time simulation method based on an RTX-HLA-reflection memory card. Background technique [0002] In order to make a distributed real-time simulation system (a typical representative is a flight simulator) achieve a realistic simulation effect, within the system, it is often necessary not only to solve various data models in real time, but also to require a deterministic network with extremely low delay time Pass data between systems so that the various subsystems can work in harmony. [0003] Traditionally, we use the solution of "high-speed Ethernet + upper and lower computer" to meet the needs of these two aspects. [0004] Limited by the TCP / IP protocol, the traditional Ethernet cannot meet the needs of real-time and deterministic data transmission between real-time simulation subsystems. Although some mea...
