摘要

目的：探寻一种新的生理信号无线测量途径，实现生理信号无线测量的普及化和大众化。方法在单片计算机信号检测模块与PC机之间加入一个串口转Wi-Fi模块，将单片计算机采集到的信号数据传到串口转Wi-Fi模块，由串口转Wi-Fi模块将信号数据通过Wi-Fi无线方式发送出去；PC机通过配置的无线网卡接收Wi-Fi无线信号，对接收到的信号进行处理并输出测量结果。结果通过串口转Wi-Fi模块，PC机与单片机之间的通信由有线通信变成了无线通信，成功实现了生理信号的无线测量。结论由于任何笔记本电脑或带无线网卡的PC机都可用作生理信号接收和处理的终端设备，所以串口转Wi-Fi模块的使用可以帮助实现生理信号无线测量的普及化和大众化。%Objective To explore a new way of physiological signal wireless measurement to popularize the physiological signal wireless measurement. Methods We added a UART-Wi-Fi module between the signal detecting module and the PC, the physiological signal measurement system transmitted the signal data collected by the single chip computer to the UART-Wi-Fi module through the serial interface RS-232C. Then the UART-Wi-Fi module sent the signal data out to the Wi-Fi wireless network. The PC received the signal data from the Wi-Fi wireless network and processed the signal data, then output the results. Result Through the UART-Wi-Fi module, the communication between PC and the signal detecting module was converted from wired communication into wireless communication successfully. Conclusion As a result of any computer can be used as a physiological signal receiving and processing terminal equipment, the use of the UART-Wi-Fi module can help achieve popularization of physiological signal wireless measurement.
