摘要介紹了在一個監(jiān)測或監(jiān)控系統(tǒng)中使用多個單片機時，單片機之間的數(shù)據(jù)交換方法。重點闡述了雙單片機之間數(shù)據(jù)交換的雙向平行、單向平行、串行、并轉(zhuǎn)串或串轉(zhuǎn)平等數(shù)據(jù)交換方式，并從硬件和軟件兩個方面分析了保證數(shù)據(jù)交換準(zhǔn)確性而采取的抗干擾措施。

Abstract The method of data exchange among multiple single chip computers in one measuring or monitoring system is introduced. The Schemes of data exchange
between two single chip computers，e. g. ，bi-directional parallel，single directional parallel ，seriral，parallel to serial，or serial to parallel，etc. are described
emphatically. The measures of anti-interference to ensure precise data exchange are analyzed from both hardware and software aspects.
