摘要：

针对现有数控监测设备使用中存在的问题，结合信号处理技术，提出一种基于虚拟仪器构建的在线监测平台的方法。阐述了虚拟仪器的特点，在此基础上开发了一个以计算机为支撑平台的多路数据采集系统与信号分析处理、管理系统，并介绍了系统的监测原理、方法和软硬件的功能结构。该测试系统实现了信号的多路采集、动态显示、实时分析处理和基于数据库的数据存储，因此提高了数控转塔冲床的整体性能。最后，利用虚拟信号发生器产生信号源并对其进行采集与分析，验证了系统的正确性。

For the existing problems of CNC monitoring equipments, a method combining with signal processing technology was proposed to construct online monitor platform based on virtual instrument. The characteristics of virtual instrument were described， based on which a mutiplex data acquisition, signal analysis and management system supported by computer platform was developed，and the systematic monitoring principle, method, hardware and software function structures were introduced. The signal mutiplex acquisition, dynamic display, real-time analysis and data storage based on database were realized, therefore the overall performance of CNC turret punch press was improved. Finally, the signal source generated by using virtual signal generator was collected and analyzed，which verified the correctness of system.
