In the future battlefield,ammunition cooperative operation in cluster mode will become the key to the growth of weapon capability.The traditional test,based on the missile group entity and field flight experiment,is complex,time-consuming and expensive.The simulation system based on distributed architecture can provide modeling tools and simulation means for the future missile swarm system,and accelerate the development and experiment of missile swarm system.This paper takes the distributed real-time simulation system as the research object,designs and constructs a set of distributed real-time simulation system based on reflective memory network and Ethernet double-layer network,and makes a complete experimental analysis.The main work is as follows:(1)Firstly,this paper analyzes the characteristics of the distributed simulation object,and puts forward the special requirements of the missile group simulation system combined with the distributed architecture.Then,according to the requirements and design principles of the missile group simulation system,the related design is carried out,the structure of the distributed real-time simulation system is given,and then the functions of the system are designed to complete the design of the overall scheme of the distributed real-time simulation system.(2)Based on the introduction of the overall scheme design of the system,aiming at the high-speed requirements of the system for network communication,this paper makes a comparative analysis of the relevant network communication means,selects the reflective memory network as the communication means of the high-speed internal network,and Ethernet as the communication means of the low-speed external network.After that,the communication protocol and shared memory are designed based on the hardware equipment.On this basis,the communication matrix is designed to simulate and calculate the communication between guided munitions.(3)Then,aiming at the main control subsystem,the paper first focuses on the analysis of its functions,then designs the main control software architecture and refines the design of each module based on the design architecture,and designs the key technologies such as collaborative data computing,shared memory mutual exclusion and system data scheduling.(4)After the completion of the simulation system scheme design,according to the scheme,the computer and other hardware needed for the system construction are connected into the communication network according to the reasonable network structure,and the software related settings are carried out to build the missile group simulation system.Finally,the paper designs and implements the simulation experiment of the real-time simulation platform of the missile group distribution,and puts forward three standards for the system performance evaluation,and analyzes the system performance and the previous design according to the experimental results.The experimental analysis shows that the design of the whole simulation system is feasible,effective and practical.All the designs in this paper have certain effects,and the experimental results meet the proposed performance indicators. |
