[Software Engineeringms51_RS-485_mutipc

Description: RS-485串行总线接口标准以差分平衡方式传输信号,具有很强的抗共模干扰的能力,允许一对双绞线上一个发送器驱动多个负载设备。工业现场控制系统中一般都采用该总线标准进行数据传输,而且一般采用RS-485串行总线接口标准的系统都使用8044芯片作为通信控制器或各分机的CPU。8044芯片内部集成了SDLC,HDLC等通信协议,并且集成了相应的硬件电路,通过硬件电路和标准协议的配合,使系统的通讯准确、可靠、快速。8044在市场上日渐稀少,虽然有8344可替代,但几百元的价位与普通单片机几元至几十元的价位相差甚远,用户在开发一般的单片机应用系统时,都希望能用简单的电路和简单的通信协议完成数据交换。譬如:利用单片机本身所提供的简单串行接口,加上总线驱动器如SN75176等组合成简单的RS-485通讯网络。本文所述的方法已成功地应用于工程项目,一台主机与60台从机通讯,通讯波特率达64KBPS。
