Description

Smart City Street Light Control System

technical field

Background technique

As an important part of urban construction, my country's urban road lighting industry has developed rapidly in recent years. There are still many problems in traditional street lamps in various aspects, and the development of new urban street lamps has become a research hotspot at this stage.

At present, there are still the following shortcomings in urban street lights:

1. Solar street lamps have become an emerging industry in the field of street lamp research due to their green and energy-saving advantages. They are widely used in daily road lighting and quickly put into market applications. Although solar street lights have obvious advantages over traditional urban street lights, there are also problems of low photoelectric conversion efficiency and unsustainable power supply in rainy days.

2. In terms of green energy saving, most street lamps are not highly intelligent. They only realize automatic switching of lights at regular intervals and non-intelligent dimming, without maximizing the energy-saving effect of the system. For example, it is impossible to accurately realize the dynamic control concept of turning on the lights when people and cars arrive, and turning off the lights when people and cars leave, and it is impossible to realize the refined intelligent control and management of street lights. In some areas, street lights are often turned on and off, and the brightness of street lights cannot be intelligently adjusted in real time according to changes in light intensity, resulting in unnecessary waste of resources.

3. At present, street lamps are still managed by distributed distribution box technology and staff cooperation. Therefore, the street lamp system needs to spend a high cost, follow-up maintenance and management work, and cannot monitor the dynamic parameters of street lamps in real time. Where the intelligent street light control system is put into use, the old street light switch mode of light control or time control is still used, and there is no novelty and personalized control strategy.
