基于Delphi多线程的串行通信构件的研究与实现

构件是实现软件重用的有效途径。文章介绍了一个基于Delphi多线程的串行通信构件的体系结构，提出了一个适用于该结构的多线程调度算法模型，讨论了在多任务并发执行环境下的多线程串口程序设计方法，以及基于这些模型和方法的串行通信构件实现的一般过程。所实现的构件在仓库管理系统实施过程中已成功应用，具有较强的重用性、可靠性、适应性及多线程并发控制特点。

THE RESEARCH AND IMPLEMENTATION OF SERIAL COMMUNICATION COMPONENT BASED ON DELPHI MULTITHREADING

Component is an effective approach to implement software reuse.In this paper,a serial communication component architecture model based on Delphi multiple threads is firstly introduced.Then,a scheduling algorithm model of multithreading to conform the structure model is presented.The details of serial communication programming in a multitasking concurrent executive environment and general realization process on the basis of these models are respectively discussed at the end of the paper.This component is successful applied to Enterprise Resource Panning system,and embodies its characteristic of good reusability,reliability,adaptability and multithreading concurrent control.
