| 摘 要： | 本文阐述了脑电检测系统的原理；系统由信号采集单元和以ARM7为核心的中央处理器LPC2132两大部分组成。信号采集单元承担了脑电信号的采集、放大滤波的任务。将处理过的脑电信号送入LPC2132芯片中，对脑电信号进行后续处理。LPC2132所实现的功能有：AD转换、数据存储、显示波形等。由于微处理器所承担的任务多且切换频繁，在内核植入了μC／OS-Ⅱ操作系统。本文详细阐述了在LPC2132微处理器中植入μC／OS-Ⅱ操作系统所要进行必要的设置和任务创建的步骤。

| Abstract: | The principle of EEG detection system is expounded. The system is composed of two parts, signal acquisition unit and LPC2132 that is CPU as the core of ARM7. Signal acquisition unit is used for acquisition of EGG, amplification and filtering noise. Processed EEG sig- nals are sent to LPC2132 for processing. The function which realize by LPC2132 includes AD transform, data storage, display waveform, etc. Because of frequently change of many tasks, μC/OS-Ⅱ operating system is implanted in microprocessor. That how to implant and set μC/OS-Ⅱ Operating in LPC2132 and how to create tasks are expounded. |
