Embodiment Construction

[0042] The existing publish-subscribe relationship among federated members is that each member adopts the publish-subscribe mode for the federated server, and the federated server needs to deliver messages to each federated member, such as figure 1 shown. When there are too many nodes in the network, most nodes subscribe to useless messages, resulting in the occupation of network bandwidth resources and server distribution service time, resulting in overall network message delays and bandwidth resource waste.

[0043] The embodiment of the present invention provides a helicopter-based multi-machine collaborative simulation framework, such as figure 2 As shown, the simulation architecture is suitable for multi-system, large data volume, and multi-machine collaborative simulation environment with high real-time requirements. The simulation architecture includes multiple federated servers, and each federated server corresponds to multiple federated members;

Abstract

The invention belongs to the technical field of computer distributed simulation, and discloses a multi-helicopter collaborative simulation architecture based on helicopters. The simulation architecture is suitable for a multi-system, large-data-volume and high-real-time-requirement multi-machine collaborative simulation environment, and comprises a plurality of federation servers, wherein each federation server corresponds to a plurality of federation members, each federation member has a message subscription function for all the federation servers, and each federation server has a function ofissuing messages to federation members connected to the federation server. Network communication support is provided for a special-shaped multi-machine collaborative simulation system, a simulation process is controlled in real time, and a universal network tool library is provided, so that expressions of subsystems of collaborative simulation and information interaction behaviors among members are more consistent.

Description

technical field [0001] The invention belongs to the technical field of computer distributed simulation, and in particular relates to a helicopter-based multi-machine cooperative simulation framework and a data interaction method. Background technique [0002] In the early stage of the development of simulation technology, it was mainly used for single-platform and single-function simulation. With the further development of computer and simulation technology, it has developed from single-platform simulation with multiple functions in the same field to multi-platform distributed interactive simulation. The scale of the system is getting bigger and bigger. As the technology grows larger, the contradiction between its complexity and integration becomes more and more prominent. With the massive application and popularization of network technology, distributed interactive technology, and various simulation support platforms, heterogeneous simulation in various fields realizes cross...
