The proposal based on USB Host/Slave controller chip CH375A,under MCU control,realized a USB-Host embedded in CAN bus data acquisition system and stored acquisition data of each node in U flash disk,supplanted a computer in field data acquisition system;

• 该方案基于USB主/从控制芯片CH375A,在单片机的控制下,既可以实现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PC机的模式;
