摘要
对微振动信号的分析处理是一项重要的技术,文章介绍了一种微振动信号检测系统,系统中采用了ATmel公司的AT89S52单片机作为控制单元,并通过过零率检测技术对振动信号进行处理,简化了国内现有的信号处理方法。该文详细分析了系统的结构、硬件组成及系统功能,同时阐述了在调试过程中碰到的问题及解决的办法。
The analysis and processing of micro - vibration signals is a key technology. The paper introduces a testing system for micro - vibration signals. This system selects megal6 of ATmel as microeontroller, and adopts zere - cross rate detection technology to process the signals. This method is simpler than existed ones in our country. The paper analyzes the structure, makeup, and function of the system, as well as the problems and the countermeasures during the debugging
