摘　　要：针对单片机与PC机的通信设计,提出了一种科学的、可行的方案,利用单片机模拟串口和PC机通信,无需增加扩展芯片;利用VB实现PC机(上位机)和单片机串行通信的程序开发,通信稳定可靠;给出了具体可行的硬件电路和相关调试程序。此设计方案充分利用了系统资源,有效地实现了PC机与多台单片机之间的远距离通信,并成功应用于一个分布式温度采集系统中。According to the design of the communication between single-chip processor and personal computer (PC), the paper offers a kind of scientific and reliable scheme, which applies the simulative port of single-chip processor to communicate with PC, dispensing with expended chip, it also applies VB to realize the development of program for tandem communication between PC (upper-post processor) and single-chip processor, thus the communication become more stable. In addition, the concrete hardware circuit and relevant debugging program is presented. The systematic resource is fully used in this design scheme, which leads to effective remote communication between PC and several single-chip processors, and successfully applied to a distributive temperature collecting system.
