摘　　要：提出了心电监护系统中WIFI传输的设计与实现。考虑WIFI模块的体积、功耗、差错率等问题选用REDPINE SIG-NALS公司的RS9110-N-11-22模块,为提高WIFI传输速度选用SPI接口的WIFI模块与MCU进行通讯,SPI接口的通讯速率可达25 MHz。MCU按照一定的数据格式把数据传给WIFI模块,WIFI模块通过TCP协议将数据传输到服务器,最终在服务器上解析出心电波形,实现不丢帧的实时传输。The design and implementation of WIFI transmission are presented in ECG monitoring system. Considering the problem of WIFI module volume ,power consumption, and error rate ,this ECG monitoring system uses RS9110-N- 11-22 module of REDPINE SIGNALS. SPI interface of the communication of WIFI module and MCU is used to improve the transmission speed, and the communication speed can reach 25 MHz. MCU transmited data to WIFI module in accordance with a certain data format. Afterwards WIFI module transmitted the collected data to server through TCP protocol. Ultimately the server side could show ECG waveform. This system can achieve real-time transmission system without dropping frames.
