摘要
介绍了采用RS4 85接口进行远距离串行通讯的原理 ,并给出了实现该系统功能的相应硬件电路 ;同时 ,为保证数据的可靠传输 ,针对通讯过程中可能出现的问题提出了相应的合理解决办法 ;该系统采用高级语言VC和KeilC5 1实现PC机和单片机的通讯 ;文中还介绍了实现通讯的基本语句和主要编程思想。
This article introduces the principle of remote serial communication by RS485 series interface and the corresponding hardware configuration which can fullfill the communication function of the system. What's more ,contraposing the problems possibly appeared in.communication procedure,some rational resolvents are given in order to keep the data trasmitted exactly. The system adopts the advanced language VC and Keil C51 compiler to implement the communication programming design between PC and Single-chip Microcontroller. Also theprogramming primitive and programmed algerithm are provided in this article.
