News - IoT Based Solar Street Light Control and Monitor System

Nowadays, with the maturity of intelligent Internet technology, the concept of “smart city” has become very hot for which all related industries are competing. In the construction process, cloud computing, big data, and other new-generation information technology innovation applications become mainstream. Street lighting, as an indispensable element in urban construction, IOT smart solar street light has become a breakthrough in the construction of smart cities. IoT (Internet of Things) Smart Solar Street Lights are the solar powered street lighting system which equips with an intelligent wireless remote solar street light control and monitoring system. Monitoring, storage, processing, and data analysis systems enable comprehensive optimization of the entire installation and monitoring of municipal lighting systems based on various parameters, make the solar street lights more efficient and easier than conventional solar street lights.

E-Lite Semiconductor Co., Ltd. has more than 16 years professional lighting production and application experience in LED outdoor and industrial lighting industry, and 8 years rich experience in IoT lighting application areas. E-Lite's smart department has developed its own patented IoT Intelligent Lighting Control System---iNET. E-Lite’s iNET loT solution is a wireless based public communication and intelligent control system featured with mesh networking technology. iNET cloud provides a cloud-based central management system(CMS) for provisioning, monitoring, controlling and analyzing lighting systems. This secure platform helps cities, utilities and operators reduce energy usage and maintenance costs, while also increasing safety. iNET Cloud integrates automated asset monitoring of controlled lighting with real-time data capture, providing access to critical system data such as power consumption and fixture failure. The result is improved maintenance and operational savings. iNET also facilitates development of other IoT applications.

Benefits of E-Lite’s iNET IoT Intelligent Lighting Control System

Remote and Real-time Monitor and Control of Operation Status

Traditional solar street lights need to be regularly checked the lamp usage by workers. If one of the solar street lights or several solar street lights is not on, or the lighting time is short, which greatly affects the customer experience, the IoT based solar street light can be viewed in real-time through the computer platform or APP at any time and at anyplace, no need send any personnel to the site. E-Lite iNET Cloud provides a map-based interface to monitor and control all the lighting assets. Users can view the fixture status (on, off, dim)，device health，etc.，and perform overrides from the map. When viewing alarms on the map, users can easily locate and troubleshoot faulty devices and configure replacement devices. User can also request collected data including the lighting working time, battery charge/discharge status, etc. If an IoT based solar street light does not turn on, you can send a worker to check and repair it. If the lighting time is short, you can analyze the reason according to the actual situation.

Grouping and Scheduling the Work Policy

The traditional solar street light’s work policy always be set at factory or during installation, and you have to go the site to change the work policy with a remote control one by one when season changes or any other special requirements needed. But E-Lite iNET Cloud allows logical grouping of assets for event scheduling. The scheduling engine provides the flexibility to assign multiple schedules to a group, thereby keeping the regular and special events on separate schedules and avoiding user setup errors. The scheduling engine determines the daily schedule based on the event priority and sends appropriate information to various groups. For example, the IoT based solar street light can increase lighting in high crime areas or emergency situations, which is convenient and fast; to increase or decrease the lighting according to weather events and at different times of the day, etc. It is very efficient.

Data Collection and Reporting

As global warming continues, every governments are concerned about energy conservation, carbon footprint and carbon emissions. iNET reporting engine provides several built-in reports that can be run on an individual asset, selected assets, or an entire city. Energy reports provide an easy way to track energy use and compare performance across different lighting assets. Data log reports enable trending selected points (e.g. light level, wattage, schedules, etc.) for a defined period of time to help analyze behavior and track any anomalies. All reports can be exported to CSV or PDF formats. This is what the traditional solar street light couldn’t supply.

Solar Powered iNET GATEWAY

Unlike the AC powered gateway, E-Lite developed the integrated solar powered DC version gateway. The Gateway connects installed wireless luminaire controllers with the central management system through an Ethernet link for LAN connections or 4G links via an integrated cellular modem. The Gateway supports up to 300 controllers up to a 1000m line of sight, ensuring secure and robust communication to your lighting network.

Sol+ IoT Enabled Solar Charge Controller

A solar charge controller gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, Sol+ charge controller maximizes this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time and maintains battery health, extending its life. Unlike the traditional NEMA, Zhaga or any other external connected light controller unit, E-Lite Sol+ IoT solar charge controller is integrated to the solar street light, which is component reduced and looks more modern and fashion. You could monitor, control and manage wirelessly the PV charging status, battery charge and discharge status, lights operation and dimming policy, you receive fault alerts with no patrol needed.
