Internet Based Remote Laboratory Architecture for 3-Phase Induction Motor Control System Experiment

To impede the spread of the COVID-19 virus, governments around the world enacted several rules such as social distancing, local lockdown, and travel restriction in accordance with WHO suggestions. These rules have caused many things such as limitation of social interaction and increased limit of public places, including campuses, schools, and other educational institution. This condition leads to the difficulties of educational activities since most classes are either canceled or moved to an online platform. Instead of classes, most of the workshops, conferences, and other activities which are important to students have been canceled or postponed. To alleviate the pandemic impact in education especially for college students this work proposed a system for conduction remote practicum safely and effectively to support the education and experience of these students. Research or practicum is important to preserve student's hands-on experience so that the student's readiness to handle the post-campus job is adequate. In this research, the proposed system architecture enables internet-based remote access of the laboratory equipment via an API with the MQTT communication protocol. The experiment is tested under a three-phase induction motor. The results show that the proposed system has the potential ability to be implemented further in the practicum activity. The average transmission time of 0,388 seconds without the Live Stream feature and 0,679 seconds with the Live Stream feature. Also, the system reliability of the proposed system could reach 98,76 percent.
