Development of marine observation system using LPWA communication system for marine IoT service

Abstract

B<span>ecause oceans account for 70.8% of the Earth's surface, various Internet-of-Things (IoT) applications for the marine industry are being researched and developed. The success of an IoT technology in the maritime industry depends on the location tracking technology used and how far it can communicate. In this study, we implemented a marine observation system using low power wide area (LPWA) communication technology to provide maritime IoT services. The proposed marine observation system consists of a marine IoT module and an ocean observation monitoring system. The information collected is GPS information and communication signal reception strength. As a result of an actual field test, we were able to obtain the distance to the gateway by measuring the position through the marine IoT module, and we found that the intensity of communication was proportional to the change in sea level.</span>

“…To prevent delays in data relay to the server, its analysis, and the final signal to operate the 'thing,' data processing is performed near to the monitor and control system. 2) Gateways and data acquisition systems [43], [59], [66], [71], [113], [140], [158], [209]- [219] A data acquisition system (DAS) collects the data given by the sensors and converts it to a digital-analog format. The DAS combines and prepares this data before sending it to the next level of processing through Internet gateways such as wireless wide area network (WANs), such as cellular or wireless fidelity (Wi-Fi), or wired WANs.…”
