System background
Urban street lighting system is an essential public facility in the city, which is closely related to people's life and a major symbol of modern city. At night, such as blazing street lights and urban landscape lights that have been continuously built in recent years, the bright light is not only limited to lighting functions, but also a business card to show the style of the city.
However, the huge urban lighting system is often accidentally damaged for various reasons, such as bulbs burned out, facilities stolen, power transmission was damaged due to brutal construction, etc. As a result, there are many problems of public security and loss of life and property, and citizens complain frequently.
Urban lighting system is also a public facility that needs to consume a lot of electric energy. With the increasing tension of energy in the world, the country has put forward the requirements of energy conservation and emission reduction.
Using the traditional methods of manual inspection and mass reporting to manage a large number of lighting facilities is obviously beyond our ability. How to achieve intelligent and effective maintenance, supervision and energy saving of street lamp lighting system, street lamp measurement and control system came into being.

System advantages
GPRS is a perfect service to solve mobile communication information service at present. It is based on data flow billing, covers a wide range, and has faster data transmission speed. The introduction of GPRS provides an infrastructure platform for Industry and enterprise users to carry out wireless office, and creates favorable conditions for promoting the application and development of mobile office. Compared with wired network, GPRS network has the advantages of low rental cost, mobile office and no geographical constraints.
application area
Street light controllers are widely used in public lighting environments such as municipal roads, highways, bridges, tunnels, gardens, docks, sightseeing lights, sports squares, amusement places, advertising light boxes, etc;
Lamp types applicable to street lamp controller: high pressure sodium lamp, low pressure sodium lamp, metal halide lamp, high pressure mercury lamp, fluorescent lamp and other gas discharge lighting lamps.
