  • LabVIEW is faster than text language based program regarding development time and can monitor the output of data fast without the separate compiling work as the graphic-based graphical programming language. And, its coding is fast because it is designed by connecting the function with the wire and its has the merit of relatively intuitive UI. In this paper, data transmission and receiving between the program that is implemented in C language as CAN communication method that is strong against noise and used in power electronics application field variously and LabVIEW based program are explained. And, the design of LabVIEW based CAN communication program, data analysis and GUI screen composition that is convenient for monitoring are shown.

  • This paper shows a monitoring program, and this Exploiting monitoring program is a program for real-time monitoring the current and voltage which is produced by wind generators. And this program helps to check efficiency and situation of the wind generator; therefore, it uses LabVIEW for this real-time monitoring program. It is expensive that the specific network is needed in the common LD (long distance) data transmission. So in this paper, it shows the transmission method which use ezTCP/LAN (Serial-port${\leftarrow}{\rightarrow}$LAN-port converter) and combine with the TCP/IP based on LabVIEW. And in this method the specific network is not needed for using the Internet network to transmit the data, which can reduce the application cost of the system.

  • In this paper, we suggest the object-oriented methodology for the design and implementation scheme for the program development in the application of control and instrumentation such as the detection system of RFID defective tags which needs the embedded programming. We apply the design methodology of UML in the system design phase, and suggest the implementation scheme of LabVIEW programs using LVOOP(LabVIEW Object Oriented Programming)in which make it possible to write the object-oriented programming. We design the class diagram and the sequence diagram using UML, and write the classes of LVOOP from the designed class diagram and the main VI from the sequence diagram, respectively. We show that it is possible to develop the embedded programs such as the RFID application through the implementation example of the detection system of RFID defective tags in this paper. And, we obtain the advantages based on the object-oriented design and implementation using the LVOOP approach such as the development of LabVIEW programs by adding the classes and the concept of object of the object-oriented language to LabVIEW.

  • A flow control system was designed and fabricated to control the flow rate of liquid through the pipe. This control system was composed of hardwares and software, hardwares as controller, gate valve, orifice meter and data aquisition board and software as National instruments Labview program. Control of flow rate was executed by adjusting the pneumatic valve located at the center of pipe line based on the control signal generated by LabView PID control algorithm, which converts analog signal measured by pressure difference of orifice to digital signal to adjust pneumatic valve. For the controller setup Ziegler-Nichols tuning technique was applied and control performances were investigated for not only the disturbance but also the set point changes. Developed system showed good control performances in flow control enough to use as teaching tool of feedback control theory and practice in university, and also as industrial application.

  • The monitoring system is an absolutely required system for improving a performance to consider the situation for the hybrid generation of the photovoltaic (PV) and wind power (WP) energy experimental research complex. This system is to monitor with the railroad switching point heating system using LabVIEW to the hybrid generation of the PV and WP. The monitoring system of this paper is a program monitoring the hour, day and total of the voltage and current that made from the hybrid generation of PV and WP. In experiment, we acquired the power data according to time at the day of PV and WP. We have confirmed the possibility of the real time monitoring system using LabVIEW with the railroad switching point heating system as the hybrid generation of the PV and WP.

  • As industrial robots come into wider use, their control techniques are being developed along with enhancements in their performance. Specially, the dynamic performance of a 6-axis articulated industrial robot is greatly changed according to the position and orientation of the robot. This means that the PI parameter tuning of the robot and orientation of the robot. This mconsidering the dynamic characteristics of robot mechanism. In this study, $LabView^{(R)}$ programming was applied to automatically conduct parameter scheduling for various robot motions. Using forward and inverse kinematics of RS2, we can divide the working envelope of RS2 into 24 subspaces. We then conduct the gain-tuning according to each subspace. Finally, we program the actual gain scheduling, in which the optimized gain-tuning for each subspace to be passed should be changed for various robot motions using $LabView^{(R)}$.

  • 최근에는 컴퓨터를 이용한 자동 제어나 계측기의 활용이 급격히 증가하고 있다. 본 논문에서는 데이터의 수집 및 제어가 쉽고 데이터 분석 및 적용이 용이한 LabVIEW 그래픽 프로그램을 사용하여 계측장비 제어 및 모니터링, 측정 데이터의 분석, 자동제어가 가능한 자동 부화 시스템을 설계하고 시스템의 검증을 위해 Incubator를 제작하였다. 센서를 통해 Incubator 내부 환경을 측정하고 부화를 위해 선택한 개체의 부화환경을 데이터베이스 파일에서 불러와 최적의 환경 조성을 위해 각 장치들을 초기화 및 제어한다. 이를 통해 미세한 부화 환경의 변화가 부화율과 품질에 주었던 단점을 극복할 수 있을 뿐만 아니라 효율적인 시스템 관리로 인한 인력과 비용의 절감도 기대된다.
