三级控制的AT89C系列多单片机系统设计

Multi-machine System Design of AT89C Series SCM based on Three-stages Control Strategy

采用AT89C系列单片机构成三级驱动的主控制器、分支控制器、终端控制器大型集散控制系统,实现了大规模、中距离、高速率、低成本的多机串行通信。

Using AT89C series SCM, the paper constructs a large -scale DCS system driven by three stages which comprise the main controller, the branch controllers and the terminal controllers. The objectives of multi - serial communication with large -scale, middle distance, high -speed, and low- cost are achieved.
