Development and implementation of smart street lighting system based on LoRa Technology

Abstract

This paper concerned with the development and implementation of smart street lighting control system based using Led lamp and Lora Wireless communication. Smart street lamps have been developed for over several years. These technologies have played an important role in urban safety, energy conservation. Currently, a traditional street lights are automatically turn on or off based on timer or day/night sensor. LEDs are now the standard replacement for legacy lighting in most cities around the world. At the same time, smart controls are becoming more mainstream and are increasingly installed alongside LED deployments. Recently, the conventional light sources are replaced by Led, which have so many advantages such as: energy savings, long lifetime, high reliability, pure light color, fast response, and friendliness to the environment. Furthermore, the intensity of the LED can be controlled easily. In this paper, the smart lighting system is designed to control and monitor devices via wireless transmission frequencies below 1 GHz. The system will include many types of devices connected to each other by a gateway. The transmit distance is about 2km in the urban area and up to 5km in rural area. The proposed smart street public lighting provides some advantages features such as: Automatic mode, Remote control mode, Connection disconnection mode, Manual direct operation mode. The smart lighting system has been built at Ho Chi Minh City University of Technology to meet the standards for data transmission. And some experimental resutls are provided to show the effectiveness of the porposed system.

Appearance Design Method of Smart Street Lamp Based on Kansei Engineering

“…e method achieves the purpose of maximum power tracking by setting an error limit so that the output of the new energy battery always oscillates near its maximum power point. Literature [8] designed an intelligent LED intelligent street light control system. e system is based on ATmegal6 single-chip microcomputer, which realizes the detection of the voltage and current of new energy photovoltaic cells and batteries, the control of battery charging and LED drive circuits, and the remote communication function, which can control or detect each street light; it is convenient for managers to control and maintain the street lights.…”
