摘要
本文将虚拟仪器技术、数字信号处理DSP技术和计算机技术紧密结合起来,以计算机为硬件平台,通过软件编程,实现对机车信号接收信息参数的检测。该方案突破了传统仪器在数据实时处理、数据交换、数据显示和数据存储等方面的诸多限制,检测方法灵活、快速,满足铁路现场的实际需要。实验结果表明,将虚拟仪器技术应用于铁路信号的检测领域具有很强的现实意义和广阔的应用前景。
By closely combining virtual instrument technique, digital signal processing technique and computer technique, with PC as the hardware platform, this paper realizes the detection of parameters of the information received by cab signaling device through software programming. This scheme can break through many limitations of the method based on traditional instrument in such aspects as real time data processing, data exchange, data display, data storage and man machine interface and so on. This method is flexible, fast and able to meet the practical requirement of railway site. The experiment results show that the application of virtual instrument technique in the detection of railway dedicated signals has practical significance and wide application prospect.
