김정현 대한기계학회 2024 대한기계학회 논문집 C. 기술과 교육 Vol.12 No.2

본 논문은 과학상자와 Labview를 이용해 탁구공 분류기를 설계하고 제작하는 메카트로닉스 설계 교육 사례를 제시한다. 학생들은 과학상자 부품의 모델로 3D CAD 모델을 설계하고 Labview로 제어하는 분류기를 제작하며 아이디어를 실천에 옮기는 메카트로닉스 시스템의 설계 과정을 경험한다. 과학상자와 Labview의 조합은 기계, 전기전자 및 소프트웨어의 융합적 특성이 강한 메카트로닉스 설계 교육에 많은 장점을 제공한다. 과학상자의 이용을 통해 학생들은 정해진 절차에 얽매이지 않고 자유롭게 아이디어를 구현할 수 있고 표준 부품을 이용하여 설계할 수 있는 경험을 할 수 있다. Labview 활용의 장점은 비교적 짧은 교육 시간으로 성능이 우수한 시스템을 구축할 수 있는 것이다. 이러한 수업 방법은 기계·메카트로닉스 계열의 저학년 설계 수업에 아주 우수한 설계교육 모델이 될 수 있다. This paper presents an educational case study on an mechatronics engineering design class that designs a ping-pong ball classifier using Science Box and Labview. Students experience the process of mechatronics design by building 3D CAD models using actual science box parts and by creating and controlling actual classifier systems using Labview. The combination of using Science Box and Labview provides many advantages for designing mechatronics systems which are a fusion of electronics, mechanics and software. Science Box provides an abundance of freedom in creating different designs and gives students a chance to design with standard mechanical parts. Labview allows students to build up an running systems with minimum training. Overall this method provides a great engineering design class model for freshman/sophmore level students in mechatronics or mechanical engineering disciplines.

In this study, LabVIEW<SUP>TM</SUP>-based programs were developed for the monitoring and control of biological processes like recombinant E. coli fermentations. Electrical signals were obtained from sensors in the bioprocess and converted into values of process variables, and electrical noise was also eliminated. Dissolved oxygen concentrations during microbial fermentation were monitored and controlled using a PID control algorithm written in LabVIEW<SUP>TM</SUP> program. Fedbatch fermentations were performed using feedback and feedforward control techniques. Amounts of concentrated substrate entering to the bioreactor were graphically displayed and saved in a file as data. A two-dimensional fluorescence sensor was used to detect various biochemicals in biological processes. A LabVIEW<SUP>TM</SUP> program was developed for the monitoring of bioprocesses with the two-dimensional fluorescence sensor, and three-dimensional fluorescence spectra graphs were displayed in real-time via client PC. A flow injection analysis system (glucose-FIA) operated with a LabVIEW<SUP>TM</SUP> program was used for on-line monitoring of glucose in a bioprocess. Signal peaks obtained from the FIA detector were analyzed by the LabVIEW<SUP>TM</SUP> program, and peak graphs were saved in a file. On-line monitored glucose data were corresponded with off-line measured glucose data well.

Global Positioning System(GPS)이 제공하는 위치, 속도, 시간 정보를 이용하는 서비스가 다양해지면서 이를 이용하기 위해 이전보다 많은 곳에 GPS 수신기가 탑재되고 있다. 이에 따라 GPS 수신기가 신호를 수신받는 환경이 다양해지면서 신호를 안정적으로 수신하기 위해 수신기의 성능을 향상시키는 연구가 진행되고 있다. 이러한 연구에서는 위성 신호를 저장할 수 있는 시스템을 구축하는 것이 중요하다. 따라서, 본 논문에서는 Universal Software Radio Peripheral(USRP)과 LabVIEW를 활용하여 GPS L1C/A 신호를 저장하는 시스템을 구축하였다. 안테나, 라인 증폭기, 그리고 USRP와 같은 하드웨어 구성 요소들을 사용했으며, USRP를 제어하기 위하여 LabVIEW를 사용하였다. 구성한 신호 저장 시스템을 검증하기 위해 저장한 GPS L1C/A 신호를 Software Defined Radio(SDR)를 이용하여 처리하고, 상용 수신기로부터 얻은 결과와 비교하였다. 이를 통해 저장된 신호들이 Pseudo-Random Noise(PRN) 번호와 신호의 전력 수준 측면에서 실제 신호들과 일치함을 확인하였다. As services that use location, speed, and time information provided by the Global Positioning System(GPS) become more diverse, GPS receivers are being installed in more places than before to use that information. As a result, as the environment in which GPS receivers receive signals becomes more diverse, research is being conducted to improve the performance of receivers to receive signals stably. In these studies, it is important to establish a system capable of storing satellite signals. Therefore, in this paper, a system for storing GPS L1C/A signals was established using Universal Software Radio Peripheral(USRP) and LabVIEW. Hardware components such as antennas, line amplifiers, and USRP were used, and LabVIEW was used to control USRP. To verify the configured signal storage system, the stored GPS L1C/A signal was processed using Software Defined Radio(SDR) and compared with the results obtained from commercial receivers. Through this, it was confirmed that the stored signals were consistent with the actual signals in terms of the pseudo-Random Noise (PRN) number and the power level of the signal.

This paper presents the optimal motion control for 3-axis SCARA robot by using LabVIEW<SUP>ⓡ</SUP>. Specifically, for optimal motion control of 3-axis SCARA robot, we study velocity profile based on finite jerk(the first derivative of acceleration) and optimal gain tunig based on frequency response method by using LabVIEW<SUP>ⓡ</SUP>. The velocity optimization with finite jerk aims at generating the smooth velocity profile of robot. Velocity profile based on finite jerk is acquired and applied to 3-axis SCARA robot by using LabVIEW®. DSA(Dynamic Signal Analyzer) for frequency response method is programed by using LabVIEW<SUP>ⓡ</SUP>. We obtain the bode plot of transfer function about 3-axis SCARA robot by using DSA, and perform the gain tuning considering dynamic characteristic based on the bode plot. These experiments have shown that the proposed motion control can reduce vibration displacement and response error rate each 33.7% and 51.7% of 3-axis SCARA robot.

In this paper, we developed a green home simulator using LabVIEW for house designers or users to assess energy saving costs in an easy and direct way. The LabVIEW simulator has a strong graphic user interface, which is intuitive to general users. Therefore, the developed simulator enables one to gather information on electric power consumed in its house and to calculate efficiency for installing green energy generators such as solar and wind power generators. As an actual application, we simulate and compare the efficiencies of installing green energy generators at various cities and seasons using the developed LabVIEW simulator. The simulation results confirm that energy saving effects of green energies are easy to calculate by the proposed green home simulator.
