摘要
利用Visual Basic串口通信技术使单片机与计算机相连接,并且在Visual Basic环境下编写数字采集虚拟频率测试系统的程序,实现对数字量信号多种参数的采集、传送、实时测量及显示(频率、周期、脉冲宽度,占空比以及TTL电平采集等)。结果表明,设计具有较准确的测量能力和广泛的实用性,系统成功实现了局域网络远程测量,界面友好。
By utilizing Visual Basic informative technology to connect single- chip and computer and editing program adopted digitally the virtual frequency detecting system under the Visual Basic circumstances to realize congregation, conveying, timing detecting and displaying （ frequency, cycles, impulse width, divine rate and TTL electricity standard aggregation. The outcome revealed the design with precise detecting capability and extensive practicability , and a perfect realization of remote detection in the abbreviation of Local Area Network and a intimacy panel.
