摘 要:振动信号采集仪通过外接传感器,将机械结构的动态物理量转换成电压信号,之后再由 AD 模块将输入的电压信号转换成数字信号。研究人员通过分析这些数据可以准确地了解被测对象的运动特征,及时发现被测对象的设计缺陷。该文设计并实现了基于 Qt 的多通道振动信号采集仪上位机软件。通过网口 TCP/IP 协议接收前端采集仪器上传的数据,支持多通道同步采集,并实时显示数据波形。

Abstract: The vibration signal collector converts the dynamic physical quantity of the mechanical structure into a voltage signal through an external sensor, and then converts the input voltage signal into a digital signal by the AD module. By analyzing these data, the motion characteristics of the tested object can be acquired accurately by researcher, and the design defects of the tested object also can be found out in time. This paper designs and implements the upper computer software of multi-channel vibration signal collector based on Qt. Receive the data uploaded by the front-end collector through the TCP/IP protocol of the network port, support multi-channel synchronous acquisition, and display the data waveform in real time.
Keywords: Qt; multi-channel acquisition; real-time display; real-time storage; time domain data analysis
