摘要
随着煤矿生产对安全要求的提高，针对以8位单片机为核心的监控分站难以满足井下安全信息处理的现状。本文提出一种利用双CPU作为井下监控分站处理核心的方案。介绍了双CPU在分站中的功能以及在功能整合时涉及的双CPU数据共享等方面硬件、软件的设计方法。
With the requirements of safety in coal industry increasing,This article presents a program： using dual - CPU as processing core in substation, for substations with 8 bit MCU are difficult to satisfy the processing of safety information. It introduces the function of dual - CPU and the design method of hardware and software in data sha- ring of dual - CPU system.
