基于神经元芯片的生物电信号测量方法研究

A Novel Biologic Electricity Signal Measurement Based on Neuron Chip

神经元芯片(N euron ch ip)是一种内部集成有3个管线CPU多处理器芯片,它将通讯协议和控制用微处理器有效地集成在一起,实现通信、控制、调度和I/O等功能。以神经元芯片为核心构成的智能测量节点,将这些不同的智能测量节点通过LON总线组成一个新型的生物电信号网络测量系统,由网络系统控制各智能节点可同时测量心电(ECG)、脑电(EEG)、肌电(EM G)、血氧饱和度(BO S)等各种生命特征参数信号。由于小波变换技术具有时、频两域突出信号局部特征的能力,系统中采用不同的母小波函数可完成对不同生物电信号的分析处理,以挖掘出新的有诊断价值的生理信息,取得了较好的效果。文中给出了由神经元芯片构成的智能测量节点的硬件构成、信号测量方法、网络系统的拓扑结构、和实际信号测量波形和小波分析结果。

Neuron chip is a multiprocessor with three pipeline CPU; its communication protocol and control processor are integrated in effect to carry out the function of communication, control, attemper, I/O, etc. A novel biologic electronic signal measurement network system is composed of intelligent measurement nodes with neuron chip at the core. In this study, the electronic signals such as ECG, EEG, EMG and BOS can be synthetically measured by those intelligent nodes, and some valuable diagnostic messages are found. Wavelet transform is employed in this system to analyze various biologic electronic signals due to its strong time-frequency ability of decomposing signal local character. Better effect is gained. This paper introduces the hardware structure of network and intelligent measurement node, the measurement theory and the signal figure of data acquisition and processing.
