本文介绍MSY-051生物电信号微计算机处理系统的软件设计和实现。根据生物电信号处理的特点,系统的软件设计成具有主程序、信号处理子功能程序及子例行程序三层次结构形式。其中,子功能程序是具有独立信号处理功能的多模式软件模块,主要包括信号的叠加平均、统计分析、频谱分析、相关处理、数字滤波等。用它们能灵活方便地构造出各种主程序。文章给出了几个子功能程序的设计思想、程序流程以及系统对人的脑电信号及其它电信号进行处理的若干结果。
This article describes the MSY-051 bioelectric signal micro-computer processing system software design and implementation. According to the characteristics of bioelectric signal processing, the system software is designed to have the main program, signal processing sub-function program and subroutine three-level structure. Among them, the sub-function program is a multi-mode software module with independent signal processing functions, including signal superposition and averaging, statistical analysis, spectrum analysis, correlation processing, digital filtering and the like. Use them to be flexible and easy to construct a variety of main programs. The article gives several sub-function program design thinking, program flow and the system of human EEG and other electrical signals to deal with a number of results.
