微型机与多台单片机的双向呼叫通信方法

The Bi-Directional Calling Communication Between Microcomputer and Multiple Single Chip Computers

提出一种微机与多台单片机之间的高效通信方式,它有三个突出的优点:主机与从机可以双向呼叫;占用CRU时间少,微机可执行多任务;单片机台数可以很多,响应迅速,工作稳定.该通信方式特别适合于集散系统、智能仪表和集散实时监测系统等重要通信的场合.

A communication method with high efficiency is stated. The communication method is used between microcomputer and multiple single chip computers. There are three features offered by this method, i.e., bi-directional calling is possible from host computer or slave computer, multiple tasks can be executed in microcomputer because of less time is occupied from CPU, many single chip computers can be linked with fast response and stable operation. The communication method is most suitable for significant communication situations, such like distributed systems, intelligent instruments and distributed real-time monitoring systems.
