Usually the covering part of large frame structure is heavy and it is difficult to measure the stiffness of the covering part. In this paper, it makes use of virtual instrument instead of traditional instrument. In addition, it adopts LabVIEW as development platform and the hardware includes stepping motor, data acquisition card of NI, force sensor and displacement sensor, etc. The portable plate stiffness tester is developed successfully, which is applied to industrial field. It is normative and accuracy for the quantitative evaluation of the covering parts stiffness, which plays an important role for guiding production. LabVIEW development platform relative to traditional instrument has many advantages, such as real-time display and storage, efficient data processing and powerful database management and so on.

Time Information

Real-time accurate level monitoring plays an important role in the field of industrial and agricultural production. In this paper, the remote real-time monitoring display system of liquid level was designed based on virtual instrument. The liquid-level data was obtained from ultrasonic sensor and data acquisition card, and then was transmitted to a remote client via ethernet without delay by the DataSocket technology. The real-time information of liquid level was displayed on the user interface of the client which was compiled based on LabVIEW. Test results show that this system can accurately monitor the remote real-time information of liquid level.

Platform Development

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.

Real Time Application

This paper discusses on attitude control of a quadcopter unmanned aerial vehicle (UAV) in real time application. Newton-Euler equation is used to derive the model of system and the model characteristic is analyzed. The paper describes the controller design method for the hovering control of UAV automatic vertical take-off system. In order to take-off the quadcopter and stable the altitude, PID controller has been designed. The scope of study is to develop an altitude controller of the vertical take-off as realistic as possible. The quadcopter flight system has nonlinear characteristics. A simulation is conducted to test and analyze the control performance of the quadcopter model. The simulation was conducted by using Mat-lab Simulink. On the other hand, for the real time application, the PCI-1711 data acquisition card is used as an interface for controller design which routes from Simulink to hardware. This study showed the controller designs are implemented and tuned to the real system using Real Time Windows Target approach by Mat-Lab Simulink.
