Abstract
In this work, an innovate system is designed and implemented to manage solar street lighting units which are distributed in urban. The designed system overcomes wireless sensor network's essential drawback used to automate these units. This drawback is represented by multi-hops networking technique. The system constructs from several clusters, each one is represented by single-hop topology of Wide Area Network (WAN). Each cluster has three type of nodes namely: lamppost stations, local station, and optionally master station. All designed stations are attached to SX1272 modem from Semtech company in order to establish the WAN. This module provides ultra-long transmission range up to 1.4 Km with high interference immunity. The system tested practically in real urban environment. It gives an excellent results with respect to maximum communication range and monitoring of vital operation parameters related to solar panel and other unit equipment's. In addition, the system performed on/off command to controlling lamp. During the test period, the designed system was very efficient in a manner it enabled operator to identify the possible system malfunctions and increase solar lighting units lifespan, reduce maintenance costs consequently it ensures the continues the service from these units.
