| 摘 要： | 提出了一种由USB接口供电的高精度数据采集器的设计方法。该系统采用具有USB接口单元的LPC2146作为微处理器，负责接收由ADS1255转换得到的数字量数据，并通过其内部的USB单元实现和PC机之间的USB数据通信。该系统作为一个便携式USB外设，使用方便，具有量程转换电路，可实现对微弱或较大的直／交流电压信号高速、高精度的测量。经过实验证明：最终采集结果完全符合设计要求。

| Abstract: | This paper introduces a design method of portable high-accuracy data acquisition system provided power resource by USB interface. The LPC2146 with USB full-speed device.MCU is applied as microcontrollers to receive digital datas converted from ADS1255.Meanwhile,the USB controller in the MCU can realize the USB data communication between MCU and PC. As a portable USB peripheral,the system picks up voltage signals with high sampling precision and rate. |
