摘　　要：以ARM7处理器LPC2210为基础设计的多通道数据采集器采用12通道的A/D转换器来转换模拟信号,处理器可将转换后的数字信号进行处理,然后在LCD屏上显示,也可在设定好通信协议后将数字信号通过USB线传给PC机上的LabVIEW软件进行数据处理、分析和显示。处理器外围硬件电路设计简单,而且具有实用性强、可靠性高、易于扩展等特点,使它具有很广阔的应用前景。The multichannel data acquisition based on ARM7 processor LPC2210 converts analog signal to digital signal, using a 12 channels A/D converter was designed. The converted digital data can be processed and displayed on LCD screen by the pro- cessor, or transmit to the LabVIEW software by USB bus after setting communication protocol, which could analysis, process, and display the received data. The data acquisition system has a wide application prospects for its simple peripherals hardware circuit, strong practicability, high reliability and good scalability.
