摘要
介绍一个心电信号远程诊断传输实验系统。它由用户终端和医院用主机两部分组成。用户终端中的心电放大器和单片机8098，完成心电信号的放大、采集、压缩和传输。医院主机对经电话线传输来的心电数据进行解压恢复、分析处理。该系统在实际电话线上进行心电信号传输实验表明其正确率优于99.9％，完全适合实际应用要求。
Presents a experimental remote transmiting system for electro-cardio-gram (ECG) signal. It consists of customer terminal and host computer.The customer terminal compounded by ECG amplifier and microprocessor 8098 completes ECG amplifying, sampling, compressing and transmitting. The host computer does decompressing, restoring and analysing of the received ECG data through the real phone line. The experiment results show that the correct rate of transmitting data through the real phone line is higher than 99. 9%. It is fitted well for practical application.
