An Engine Dynamic Signal Testing System Based on Virtual Instrument Technology
Aimed at the requirements of engine experimental research，a test system of engine dynamic signal was developed based on virtual instrument technology. The integral structure design of the system was given, the hardware is composed of sensors, signal conditioning module, high-speed data acquisition card and portable computer; the host computer software was developed with DASYLab, a virtual instrumentation tool. Its essential is to make good use of computer to achieve and extend functions of traditional instruments, by comprehensively using technologies of computer, digital signal processing, standard bus and software engineering method, functions of continuous multi channel sampling and multi type signal acquisition, and processing analysis were realized. The field test shows the system works reliably, development and application of this system can provide detailed experiment data and a new way in the field of engine power detection.
