With the research and application of Virtual Instrument technology and networked testing technology, the networked virtual instruments appear great potential in remote testing field of electronic equipment. This paper first presents a novel testing system of complicated electronic equipments based on virtual instruments, then building the architecture of the network and designing the hardware, software...
On the basis of the combination of virtual instrument and database technology, a fault diagnosis system for ship electromechanical system is developed. The whole structure, principle and key techniques are described in detail. Visual software is designed with the powerful tool, Visual C++. By using ODBC techniques, the problem of sharing data between Visual C++ and database is solved. Agilent data...
The remote testing methods and diagnostic modes were analyzed to meet the needs for the vehicle remote testing and diagnostic technique of vehicle maintenance enterprises. The vehicle comprehensive property remote testing and diagnostic platform established with the application of the remote virtual instrument test technique, so that the remote network testing of the system was achieved.
Motor's abnormal vibration signal includes its fault information, effective testing and analysis of its vibration signal is the key to realize motor fault diagnosis. Vibration testing and analysis system was put up to realize the acquisition, display, analysis, storage and replay of vibration signal by using NI-WLS9234 Data Acquisition Card in this paper. Call the analysis function of wavelet in MATLAB...
The objective of this work is the design and development of the data acquisition and storage parts of a monitoring system that will be used for a certain control and guide equipment. The data captured and stored in a database will be an application that will diagnose failure of control and guide equipment. Data acquisition and data store were developed using finite-state machine model and virtual...
On the base of the vibration mechanical model and the motion equation of automobile suspension built. Analyze and bring forward the performance evaluation index of the suspension, and put forward the new testing method of the suspension performance. Using the virtual instrument technology, we develop the automobile suspension performance testing system. It adopts the PC-DAQ scheme. On the base of...
