摘　　要：为满足移动数据采集及固定设备长时间存储需要,设计一种通用型可视化便携式数据采集终端系统,该系统由单芯片U盘读写方案(PB375A)、现场可编程门阵列(FPGA)及单片机构成。他提供通用异步接收/发送装置(Universal asynchronous receiver/transmitter,UART)、串行外围设备两种输入接口(Serial peripheral interface,SPI),以及U盘、SD卡两种存储接口。实验结果表明,系统的平均存储速率达到100Kbps,能实现用户可视化操作,稳定性好,携带方便。In oder to meet the needs of data acquisition in mobile or fixed occasions for long time, a porta- ble and universal data collector is present in this paper. The system consist of FPGA, MCU and U-disk control- Ier--PB375A. It provides two input interface of UART（Universal asynchronous receiver/transmitter） and SPI （Serial Peripheral interface）, also provide two memory interface of U-disk and SD-card. It was proved that, the collector system can achieve 100kbps average write speed. It＇ s operation is visual for users, have a good stabili- ty and easy to carry.
