| 摘 要： | 本文给出了一种ＭＣＳ—５１多机系统的拓朴逻辑结构及实现方法．该系统的联接仅用一对双绞线，通讯口利用８０３１串行口加上ＭＣ１４８８、ＭＣ１４８９构成，故使于实现或时原有单机系统的扩展．文章分析了系统的拓朴结构和通讯协议．为证实文中提出的方法，介绍了实例“自动寄包柜系统”．

| Abstract: | In this paper the author presents a new approach to create a multicomputer system using MCS-51's. the interconnection of the entire system depends on a simple pair of twisted wires. As MC1488 and MC1489 are added to the 8031 serial interface to create the RS- 232 - C interface between CPU's, it is convenient to implement this kind of system or to expand a control system which uses a single CPU. this paper also analyzes topology communication protocol support. Finally, a sample is given to prove the validity of the theory. |
