多线程数据通信系统的Petri网建模

根据多线程数据通信系统的设计需求,建立数据传送模块的Petri网模型.运用模型对数据传输过程所涉及的线程之间的同步协作、线程对共享资源的独占性存取、线程启动与结束时机判断等问题做模拟分析,并给出通信数据队列的多线程软件解决方案.该方案可以提升多线程串行通信程序的安全性和运行的稳定性.

A multithread data communication system with Petri net modeling

A Petri-net model for the data transmission module is established in this paper according to the design requirement of the multithreaded data communication system.This model is used for simulating and analyzing the issues involved in the process of data transmission such as synchronous collaboration between threads,exclusive access to shared resources,and choice of the right time about starting or ending of thread.Based on the analyze result,an efficient multithreaded communication software solution for the data queue is presented.This software solution can enhance the security and stability of the multithreaded serial communication program.
