Problems solved by technology

[0004] On the other hand, computer simulation has higher and higher requirements for large data transmission and high real-time performance of simulation. Traditional distributed transmission networks are difficult to meet the requirements of distributed simulation for high-speed data transmission. Distributed simulation transmission network has become a distributed simulation network. a bottleneck of
Most of the current operation support systems are based on the physical shared storage architecture and message passing network structure. The transmission rate of the message passing network mode is low, and it is difficult to meet the high-speed and real-time characteristics of distributed simulation. The physical distance supported by the physical shared storage network and the computer The number is limited, it is difficult to meet the characteristics of distributed simulation distribution
These two structures have their own disadvantages and cannot meet the needs of large-scale and complex distributed simulation

Abstract

The invention discloses a high flux distributed type simulation support platform, a system and a simulation method based on the HLA, and is designed for large data amount simulation processing. The high flux distributed type simulation support platform based on the HLA includes that a runtime infrastructure (RTI) gateway and a RTI local process unit transmit data by calling a high flux data transmission control module. The high flux distributed type simulation support system comprises a reflective memory network and at least two simulation support platforms, wherein the reflection memory network comprises a multimode optical fiber and reflection memory cards connected with the simulation support platforms. The high flux distributed type simulation based on the HLA includes that internal interconnection and interoperation of federates are achieved through the reflection memory cards, and the reflection memory cards and the RTI gateway are connected by the reflection memory network to perform management and communication. The high flux distributed type simulation support platform, the system and the simulation method based on the HLA have the advantages of being applicable to simulation of big data high-speed transmission, low in delay, high in instantaneity, and rapid and reliable in data transmission.
