摘　　要：系统结构紧凑,采用89C52单片机作为中心控制单元,应用12位高精度并行A/D转换芯片AD574和8通道故障保护模拟开关MAX354实现8路数据采集;不仅记录采集的数据,而且利用串行实时时钟芯片DS1302记录数据出现的时间,有利于用户准确了解和把握生产过程的状态;与上位机进行通讯,将采样数据和采样时间存储在上位机文件中,便于数据的查询和分析,给工业过程的长期正常运行和检查带来了很大的方便。The system is compact, using single-chip microcomputer 89C52 as central control item, realizing data sampling of 8 roads through AD574 and MAX354. It not only records the acquired data, but also records what time it happened using timekeeping chip DS1302.There is communication between this system and a host computer, which stores the sampled data and its time in a document, it is very useful for querying and analyzing data, and helpful for long-time working of the industry process and checking on it.
