本文设计了一种脱离PC 机的数据采集系统。该系统选用ISP1362 为USB 接口芯片,在Host 模式下实现脱机数据采集。解决了在不能安放PC 机的场所无法进行数据采集的问 题。测试结果表明,本系统能够满足8 路同时采集,单路采集速度为100ksps,传输速度可达8Mb/s。对野外现场数据采集有着重要意义。 关键词:USB;ISP1362;脱机式数据采集;海量存储器 Abstract:In paper the data acquisition system off PC is designed,using ISP1362 technology of Philips Company,it has realized data acquisition off PC, Solved the question of data acquisition without PC.the test results indicate that the system has 8 channel and the conversion speed of each channel is 100ksps,the data transmission speed is 8Mb/s. It has the signification for data acquisition for on-the-spot data. Keywords:USB;ISP1362;data acquisition off PC; Mass Storage Device
