黑米发酵微机监控系统的设计

The Design of the Microcomputer Monitor and Control System of the Black-rice Wine

介绍了黑米发酵微机监控系统的软硬件设计。对该系统采用的双路通信线路轮流切换的冗余技术和带光电隔离的RS－232C电流环技术进行了论述，并对支持这些技术的通信机制进行了讨论。

The hardware and software design of the black-ricewine monitor and coed system is described. In specially,introduces the implementation of duplex transmission lioc andRS - 232C interface with opto-isolated current ring, and thenwe discuss their communication mechanism.
