摘要
在PC机与多个单片机的串行通信基础上,从硬件和软件两方面完成了智能数字传送器的设计。智能数字传送器实现的是一台上位机(PC)机和8台下位机(单片机)的串行通信,上位机软件采用VisualBasic编程,作出十分直观的人机界面,并通过串行口将下位机的数据传送给上位机,上位机可作出应答信号,同时上位机(PC)机可向下位机(单片机)发出数据请求。系统具有对数据的修改,显示和报警等功能,目前在工业控制领域中应用非常广泛。
Basing on the serial communication between PC and single-chip microcomputers,the design of the intelligent digital conveyer is finished from hardware and software two aspects.The intelligent digital conveyer realize serial communication between a host computer （PC microcomputer） and eight slave computers（single-chip microcomputers）,the software of host computer uses Visual Basic programming,makes the extremely direct-viewing man-machine contact surface,the data of slave computers can transfer to the host computer through the serial mouth,at the same time the host computer can send out the data request to the slave computers.This system can modify, display and alarm data.Presently,it is widely used in industrial control areas.
