基于USB的CAN总线数据采集的大容量存储

Large Capacity Storage of CAN Bus Data Acquisition Base on USB

介绍了在CAN总线数据采集系统中应用U盘作为采集数据的移动存储器的方案。该方案基于USB主/从控制芯片CH375A,在单片机的控制下,实现了CAN总线数据采集系统中嵌入USB主机,从而完成把各节点采集的数据存入U盘,取代了现场数据采集系统必须有一台计算机的模式。

An Application with USB Flash Disk as a removable storage device in CAN bus data acquisition system is introduced. The proposal based on USB Host/Slave controller chip CH375A,realized a USB-Host embedded in CAN bus data acquisition system and stored acquisition data of each node in U flash disk under MCU control.It supplanted a computer in field data acquisition system.
