基于ENC28J60的局域网心电采集系统的设计

设计一种基于新型网络控制芯片ENC28J60的局域网心电采集系统。系统主控制芯片采用ARM7内核的LPC2148。在处理上,首先在模拟前端对心电信号经过放大和滤波处理,再AD转换后经信号隔离,然后送至局域网中主机端进行多通道波形显示和存储。实验证明本系统具有稳定性强、功耗低、安全性高及使用方便等特点,且同时满足采集和显示的要求。此系统适用于病房的心电远程监控,促进了病房监护的自动化进程,具有很好的市场应用前景。

Designing a LAN ECG Acquisition System Based on ENC28J60

To design a LAN ECG acquisition system based on a new network control chip of ENC28J60. The main control chip was LPC2148 with ARM7 core . In the analog front-end , the ECG signals were amplied and filtered , also conversion operated between AD before the signal isolated. And then the digital signals were sent to the server, on which a multi-channel waveform display was showed and the data was stored. Many experiments proveed that the system was of high stability, low power consumption, safety and ease to use. This system can be used for cardiac remote monitoring and promote the modernization of ward monitoring. It alse has a potential market prospect.
