摘　　要：随着现代控制系统要求的不断提高,如何实时、准确地在单片机和上位计算机之间传递数据已经成为系统设计中的一个重要组成部分。以压桩机智能测控系统中的基本通信模块为例,介绍了在VisualBasic环境下利用MSComm通信控件开发Windows环境下单片机与普通微机进行串行通信的方法;并提出了一种利用单片机P3口中的模拟异步通信控制信号来解决通信中同步问题的新方法。With the rising requirements of modern controlling systems, how to transfer data truly and fast between the microcomputers and superior computers becomes an important part to design a system. This article introduces how to develop serial communication programs between the microcomputers and superior computers using the MSComm Control of Visual Basic by presenting an example of an intelligent controlling system for the pile-drilling machines. Importantly, a new way to realize the synchronous communication is introduced by the P3 interface of the microcomputers.
