为了实现对人体脑电信号的实时采集,设计了一种基于 ADS1298与 WiFi 的无线脑电信号采集与传输系统.该系统主要由 ADS1298信号采集模块、MSP430主控制模块、GS1011处理发送模块3部分组成.ADS1298对脑电信号进行24位高精度的模/数转换,并通过 SPI 发送给 MSP430进行分析处理,最后发送至 GS1011进行打包,并由 WiFi 发送给远方的控制台.在提高脑电信号采集精度的同时,又运用成熟的 WiFi 无线传输技术,提高了传输速率和传输距离.该系统还具有体积小、便携、超低功耗等特点.

To realize real?time aquisition of the EEG signal from human body,an EEG signal wireless acquisition and trans?mission system based on ADS1298 and WiFi was designed. The system mainly consists of signal acquisition module ADS1298, main control module MSP430,and processing and transmission module GS1011. The analog?to?digital convertion of EEG signal is executed by 24?bit high?precision chip ADS1298,the converted signal is sent to the MSP430 for analysis via SPI,and then transmitted to GS1011 for packaging and finally to the remote console by WiFi. While improving the acquisition accuracy of EEG signal,the mature WI?FI wireless transmission technology was adopted to improve the transmission rate and distance. The system has the characteristic of ultra?low power consumption,and is small and portable.
