MCS-51-Ⅰ单片机(光纤)集散系统是将一台主机(Apple-Ⅱ或MCS-51-Ⅰ单片单板机),经RS-232C串行接口,通过智能通信机与8台MCS-51-Ⅰ单片单板机相连。主机可与8台分机中的任何一台进行双向通信。此集散系统具有通用性,根据具体对象,配以一定的应用软件,可应用于多种场合。如再配上光端机和光缆,可以增强系统的抗干扰能力,扩展传输距离。本文介绍集散系统的设计思想、调试方法,重点介绍其核心部分智能通信机(简称通信机)的设计。
MCS-51-Ⅰ SCM (optical fiber) distribution system is a host (Apple-Ⅱ or MCS-51-Ⅰ single-chip single board), through the RS-232C serial interface through the intelligent communication machine with eight MCS- 51-Ⅰ single-chip single-board machine connected. The host can communicate bidirectionally with any of the eight extensions. This distributed system has versatility, depending on the specific object, together with a certain application software, can be applied to a variety of occasions. If matched with Optical and fiber optic cable, you can enhance the anti-interference ability of the system to extend the transmission distance. This article introduces the design of distribution system, debugging methods, focusing on its core part of the intelligent communication machine (referred to as the communication machine) design.
