【摘要】 利用现行GPRS网络将便携式心电设备无线接入Internet,再将采集的心电数据上传到心电诊断服务器,设计一心电采集通信系统。硬件上系统采用Atmel公司的AT91SAM7SE512做MPU、SIEMENS公司的MC55做GPRS通讯模块。软件功能在嵌入式实时操作系统uCOS以及图形界面uCGUI下编程实现,选择TCP/IP协议进行通信。最终系统可以实现心电数据的实时采集与本地显示、本地存储,并可以选择通过无线网络上传给诊断服务器,以短消息的形式接受服务器下发的诊断结果。更多还原

【Abstract】 The portable ECG communication system in this design uses the GPRS network to access Internet,and uploads the collected ECG data to the diagnosis server.The system uses the AT91SAM7SE512 manufactured by ATMEL company as the CPU,and adopts SIEMENS’s MC55 as the GPRS communication module.The software programming of this system is based on RTOS,uCOS and uCGUI,and the communication use the TCP/IP protocol.Finally the system can achieve real-time ECG date acquisition,display and storage locally.Furthermore,the ECG date can be uploaded to the diagnosis server,and the result from the diagnosis server be accepted in the way of short message through a wireless network.更多还原
