| 中文摘要:为保障船舶安全驾驶，设计一种无线脉搏信号采集系统.系统采用单片机STC12LE5608AD作为控制器，定时采集脉搏信号，然后通过串行外设接口(Serial Peripheral Interface, SPI)将采集到的脉搏信号数据写入无线收发芯片CC2500的寄存器中并发射出去，接收端同样通过单片机将CC2500寄存器中的数据读出，再由通用异步收发器(Universal Asynchronous Receiver/Transmitter, UART)传入计算机进行实时显示并深入处理存储的数据.无线传输的方式使系统在不影响船舶驾驶员操作的情况下对驾驶员的疲劳程度进行量化，并分析全部窦性心搏间期的标准差(Standard Deviation of NN intervals, SDNN).该系统具有低功耗和便携易用等优点. |

| Abstract:o ensure safe navigation of ships, a wireless pulse signal acquisition system is designed. The system employs singlechip STC12LE5608AD as controller for timing acquisition of pulse signal. The acquired pulse signal data are written to the register of transceiver CC2500 via Serial Peripheral Interface (SPI) and transmitted. The receiver also reads the data from the register of CC2500 by singlechip. Then the data are sent into computer via Universal Asynchronous Receiver/Transmitter (UART) for displaying and further processing. The mode of wireless transmission insures that the degree of ship officers’ fatigue can be quantized and analyzed through Standard Deviation of NN intervals (SDNN) without affecting operation of ship officers. This system is of advantages of both low power consumption and portability. |
