Abstract

This paper presents a simple and costs effective equipment design multi-feeder data logger for recording and monitoring power quality. The system design uses remote supervising and multi-feeder data logging system (RESMOS). The data collected through resmos portable unit (RMPU) will automatically be saved with the format as binary and comma separated value (CSV). The time setting on the RMPU can be configured with minimum one minute per logging. This data logger uses a single transducer with a multiplexer for recording and monitoring ten channels of power quality at busbar. The system design has been validated with national metrology laboratory scientific and industrial research institute of Malaysia (SIRIM). This tool has the advantage that it can be used to measure harmonic data more than 21st at the same time for ten channels and equipped with software making it easier for analysis data with low operational costs versus another power quality equipment. The experimental results indicate that the proposed technique can accelerate data reading with conversion rate one sample per second for each channel. The device can be used to measure harmonic level and power quality with a confidence level above 95% and percentage error under 2.43% for total harmonics distortion (THD) and 1.72% for voltage harmonics.

Pada artikel ini ditampilkan simulasi pengendalian volume air dalam tangki melalui pengaturan inlet (qin) melalui hardware yang terhubung pada arduino dengan GUI LabVIEW. Antarmuka antara LabVIEW dan Arduino diatur oleh adalah LabVIEW Interface for Arduino (LIFA) melalui koneksi serial melalui USB (COM9). Model tangki yang digunakan adalah masukan dan keluaran tunggal atau single input single output (SISO). Pada hasil simulasi, didapatkan dengan pengaturan nilai qout tertentu (0 – 5 liter/s) maka dapat dipantau volume tangki dengan mengendalikan qin  (0 – 5 liter/s) melalui pengaturan potensiometer. Kata Kunci:  LabVIEW, LIFA, Arduino, Level Tangki, SISO  ABSTRACT Liquid Level Tank Monitoring is an important and vital issue in many industries such mining or oil and gas. In this article shown a simulation water volume control in the tank by adjustment of hardware connected to Arduino and using GUI LabVIEW. The interface between LabVIEW and Arduino is drived by LabVIEW Interface for Arduino (LIFA) by using serial communication USB (COM9). Tank model used is a single input single output(SISO) tank. Result of this article, by adjust qin (water inlet, 0-5 liter/s) represented by potensiometer and determined value of qout (water outlet) ,then  we can monitor and control water volume in the tank.  Keywords: LabVIEW, LIFA, Arduino, Level Tangki, SISO

Abstract

The firefighting robot contest is an event to encourage high education students to explore electronics and robotic skill. The difficulty level of the contest increases from year to year though the arena layout is relatively similar. The field of arena consists of maze, detachable doors and distractorswhich requires smart idea to enable the robot to be well-performed. The combination of home position and random fire spot at each round of the game make each team have to find the most effective method to win the match. This paper presents an implementation the grid map method on the Azmi four legged robot using ultrasonic PING sensor, GPYA021 infrared sensor and GY-955 gyroscope. An ultrasonic sensor is attached on each of four sides of the robot. The data from each sensor will be interpreted as the distance of the front, right, left and back of the robot relative to the wall. Interpretation depends on the robot's current position. Virtual mapping technique was used by assuming that the arena consists of grids which have uniform size. Each grid was given a consecutive index numbering i.e a symbolic number which in practice be manifested in terms of distance unit. The results showed that the grid map method in this study worked well, tested on four randomized configurations, the robot successfully carried out the search task and returned to the home position with an acceptable execution time.
