STC15和CH376的实时海量数据采集系统设计

Real-time Massive Data Acquisition System Based on STC15 and CH376

设计了一种基于STC15单片机的U盘实时海量数据采集系统。该系统利用USB接口芯片CH376对U盘进行读写操作,利用实时时钟芯片DS12887实时采集记录数据的时间,将采集到的海量数据以EXCEL文件形式存储在U盘中。实验结果表明,该方案能够采集、存储海量数据而且还兼顾成本低、通用性强、移动性好等优点,具有一定实用价值。

A design of U disk real-time data acquisition based on STC15 platform is proposed. The system uses USB interface chip CH376 to read and write U disk, and uses the real time clock chip DS12887 to record data acquisition time, the massive data collected are stored in EXECL files in the U disk. The experimental results show that the system can collect and store massive data,and also have the advantages of low cost, strong versatility and good mobility, so it has a certain practical value.
