基于MSC-51的主从式多级分布系统

The Master-slave Multistage Distribution System based on MSC-51

现代工业控制领域,实现主从节点间的相互通信是十分重要的,其中主从式多级分布系统是最广泛应用的模式。设计以MSC-51串行口通信协议为基础,基于通信技术,以单片机控制技术为核心,实现主机控制从机,从机反馈信息到主机的多级通信过程。该系统根据按键输入的信号,经单片机的控制处理并产生不同的与输入信号对应的输出信号,最后通过数码管显示相应的数据。实验的实际结果表明该系统具有电路简单、成本较低、操作方便、灵敏可靠等优点。

In the modern industrial control field, the principal- subordinate between nodes communicate with each other is very important, including master-slave multistage distribution system is one of the most widely used model. This system is based on MSC- 51 serial port communication protocol, based on the communication technology, single-chip microcomputer control technology as the core, and realizes multistage communication between host and from the machine.In this system,the signals from the input keys control and processing by the single-chip microcomputer and produce the corresponding output signals different with the input signal, finally through the digital tube display the corresponding data. The actual experiment results show that the system has the advantages of simple circuit, low cost, easy operation, sensitive and reliable.
