DESIGN AN IoT GATEWAY FOR MONITORING AND MANAGING SYSTEM OF LOW-VOLTAGE DISTRIBUTION CABINET
This paper proposed a method to design and implement an IoT Gateway to apply for monitoring and controlling low-voltage distribution cabinet via the Internet. This gateway uss an open source operating system and Single Board Computer (SBC) that supports various network interfaces, allowing communication of various devices in low-voltage distribution cabinet and the Internet. This gateway solution is therefore low-cost, likely easy to extendsoftware based on the open source Linux operating system, and easy to implement network protocol architectures. Results of implementing and testing gateway for MODBUS and MQTT protocols give outcomes that meet practical requirements.
