Intelligent Control System for LED Street Lighting
  • March 14,2017.
1. Background

1)Intelligent LED street lighting control system, is based on ZigBee, GPRS, WSN and other advanced wireless Internet technology, using a unified monitoring platform, combined with GIS geographic information system, without changing the lighting, without increasing the wiring , can control LED street  lights remotely. Combine with switches, dimming, monitoring, alarm and other single-lamp control, loop control and scene lighting control functions, to make the LED street lighting more energy-saving, more easy to control and intelligent.

2)The problems of LED street lamp project at present.
a) Control method is behind the times
At present, most all street lighting project adopt the time control and centralized control, and the remote control and intelligent control can not be realized when the seasons and the environment change.
b) Low level of information technology
In the management task increase largely everyday, but management manpower can not be unlimited increase, we need to improve the level of information management.
c) seriously waste of electrical energy
Can not light according to certain situation and time, wast lots of energy.
d) Operate and maintenance difficulties
Huge inspection and vehicle cost, difficult to maintenance, can not monitor the cables in case of stolen from thieves.

2. Intelligent LED street lighting control system components
LED street lights: compatible ZigBee, DALI, 0-10V system

Single lamp controller

Centralized manager

Application software

3. System functions
1)Remote switch on/off: can remotely control any one set, groups, lines of LED street lighting.
2)Remote dimming: can remotely apply dimming application to any one set, groups or lines of LED street lights;
3)Status monitor: can always check the street lamp switch state, brightness, current, voltage, power and other data;
4)Automatic inspection: the system has the function of automatic inspection, to replace the manual inspection;
5)Automatic operation: the system can automatically set up a good lighting strategy, can achieve the timing switch lights, sub-time dimming;
6)Scene lighting: can be customized to set any partition, group, time and compartment lights illuminate
7)Fault alarm: malfunction alarm, fault detection, fault handling tracking function;
8)Remote reading: auotomatically detect the consume of electricity cost per light ;
9)Data report: daily, monthly and annual statistics of power consumption, energy saving rate and other data, and generate related statements;
10)History records: can save at least one year of operating history, can be traced back to the operation error problems;
11)System display: can display the system structure and related important information;
12)Equipment management: can manage single lamp controller, centralized manager and other equipment, including entry, modify, delete, query and other functions;
13)Hierarchical permissions: different levels of users can set up different management areas and operating permissions;
14)Map function: system can integrate GIS geographic information system, can view and manage any one LED street lights on the map;
15)Scalability: The system uses B / S structure, providing open interface, with access to intelligent city platform.

4. System advantage

1)More energy-saving: reduce energy waste, effectively save electricity, while reducing carbon emissions, protect the environment.
3)Intelligent control: to achieve a remote control, intelligent control, on-demand lighting.
3)Information management: manage all the led street lights through system, can record the data, statistics, analysis.
4)Efficient operation and maintenance: automatic inspection instead of the traditional manual inspection, saving a lot of manpower and other resources.
5)Improve the lighting rate: the system can be real-time monitoring of lamp operating status, timely control of fault lighting information.
6)Extend the lamp life: on-demand lighting not only can keep energy saving, but also can extend the life of the lamp.
7)Maintain safe society: reduce traffic accidents caused by lighting failure and various social security accidents.
8)Construction of smart city: the system can be connected to the smart city cloud platform, assistance smart city construction.
