基于Petri网的综合电子系统总线建模与性能优化

摘要

针对综合电子系统运用中总线效率不高等问题，以某型步兵战车综合电子系统为例，通过对系统进行信息流规划，结合总线协议和实现机制，采用赋时颜色Petri网对综合电子信息系统通信机制进行建模，实现综合电子系统总线通信协议机制的仿真。通过对系统总线性能指标参数的分析，提出综合电子信息系统总线的优化方案。关键词：赋时颜色Petri网；综合电子系统；总线建模；性能优化%Aiming at the problem of low efficiency for application of integrated electronic system, taking integrated electronic system of some infantry vehicle for example, this paper programs the information flow of the system, integrating with its bus protocol and implementation mechanism, sets up a model of communication mechanism of the integrated electronic system based on Colored Timed Petri Net（CTPN） , and realizes the simulation of bus protocol of the system. Through analysis and study on bus performance parameters of the system, it puts forward optimization schemes of the bus protocol.
