The project designed and implemented was an EEG as the first part of a macro project, which allowed the integration between the different programs of ANTONIO NARIÑO University. This system is an integral part of the physiographer, conditioning circuits, filters, amplifiers, a data acquisition system and a virtual instrument were designed that capture the variables through a data acquisition card to be analyzed and visualized dynamically on a personal computer. Design and implementation process were divided into 5 modules. It will begin describing magnitudes to be measured, the sensors that will give us a better capture of our signals, the next two modules are the circuitry and the patient protection, to finish with data acquisition and the visualization in a personal computer.

Based on the analysis of the testing automatic transmission (AT), the AT’s solenoid valve control signals conditioning circuits and revolving speed F/V converter conditioning circuits are designed, and the data acquisition system is designed based on virtual instrument. The system is composed of the PCI-6024E data acquisition card, signal conditioning circuits and computer, and the acquisition procedure is programmed in graphical language LabVIEW. Finally, the data acquisition system has been verified on vehicle test bench which loads ZF-Ecomat 6HP500 AT. Controlling signals of switching solenoid valves, duty cycle signal of proportional solenoid valve, accelerator aperture signal, oil pressure signals and speed signals are collected, it turns out that the data acquisition system has good feasibility.

A data acquisition system for electronic automatic transmission test, which makes use of American NI’s data acquisition card, is designed based on Virtual Instrument. The data can be collected by the data acquisition system include automatic transmission oil pressure, solenoid duty, as well as speed of turbine and output shaft of transmission and throttle degree of engine and so on. The key problems of the system design are measurement method of automatic transmission solenoid duty, signal conditioning circuit design and how to improve sampling rate of the system. Test platform is of a armored vehicle which has equipped a high-power electronic automatic transmission. The automatic transmission shift control strategy and characteristics of throttle oil pressure etc can be obtained through test data acquisition.

Based on LabVIEW, this paper presents a design scheme of data acquisition, which it proposes using computer and ordinary data collection card as the main hardware and LabVIEW as software development platform, thus constructs the virtual instrument system for signal acquisition. The system can realize synchronous data acquisition of single channel or multi-channel signal, as well as real-time display and preservation. The practice shows that this scheme can not only effectively play performance of ordinary data acquisition card, but also reduce greatly program development time and beautify interface through LabVIEW which has powerfully visual human-machine interface editor and graphical programming function.

Friction wear testing machine is generally used in researches of various friction wear mechanisms, explorations of influences factors, and property evaluations of friction pair materials. Measurement accuracy and automation level of the friction wear testing machine directly influence the precision of data acquisition and analysis processing, as well as the intuition of data displaying. Based on virtual instrument LabVIEW, a data acquisition system of friction wear testing machine was developed. Hardware of this data acquisition system mainly consists of sensors utilized as acquiring information on rotate speed, normal pressure, friction force and temperature, as well as signal conditioning module and data acquisition card. Utilizing the LabVIEW, data processing and interface displaying software was programmed. Debugging results confirmed that the developed system can accurately acquire the demand information when operating the friction wear testing machine, also intuitively display these obtained information in real-time. Therefore, the developed data acquisition system satisfies the demand of precisely acquiring information related to friction wear testing of experimental materials.

A novel control platform for the permanent magnet linear synchronous motor (PMLSM) drive system has been built up based on virtual instrument (VI) and relavant data acquisition card (DAQ) devices. In the traditional control platform, it mostly depends on digital signal processor (DSP), which needs a lot of time to further develop the interface between the personal computer (PC) and operators, and its computational capability is not strong than computer. To overcome these shortages, a novel control platform is presented on the base of one PC, one LabVIEW, and one multifunctional data acquisition card. Firstly, a space vector pulse width modulation (SVPWM) signal source is executed in the VI. Then in order to improve the precision of control system, the field oriented control (FOC) is proposed for the PMLSM. Finally comprehensive experiments verify with relative simulations.

We developed a system of μ-PIXE analysis at the division of Takasaki ion accelerator for advanced radiation application (TIARA) in Japan Atomic Energy Research Institute (JAERI), which consists of a microbeam apparatus, a multi-parameter data acquisition system and a personal computer. Elemental analysis in the region of 500 μ m × 500 μ m can be performed with a spatial resolution of < 0.3 μm and multi-elemental distributions are presented as images on a computer display even during measurement. We call this system a micro-PIXE camera.
