Solar street lamp control system and method based on time, illuminance and visibility

Abstract

The invention provides a solar street lamp control system based on time, illuminance and visibility. The system comprises a solar photovoltaic module, a controller, a storage battery and a lighting street lamp. The input end of the controller is connected with a photosensitive probe and a camera. Time, illumination intensity and visibility serve as trigger conditions of the controller, wherein the trigger conditions are used for controlling the lighting street lamp to be turned off and turned on. A solar street lamp control method includes the steps that (a), a located period is judged; (b), illumination intensity is judged; (c), a grey level image is collected; (d), visibility is judged, and if V is smaller than Vi, the step (e) is executed; (e), the street lamp is turned on. By the adoption of the solar street lamp control system and method, the turn-on state of the lighting street lamp can be controlled in the aspect of time, the lighting street lamp can be turned on when external illumination intensity and external visibility are lower than set values, the lighting function on overcast and rainy days, foggy days and hazy days is achieved, and traffic accidents are avoided.

Description

technical field [0001] The present invention relates to a solar street lamp control system and method, more specifically, to a solar street lamp control system and method based on time, illuminance and visibility. Background technique [0002] Street lighting is an important part of public facilities in urban construction. With the increasing scale of cities, how to achieve an effective balance between saving energy and ensuring the quality of street lighting has become an important issue for urban development in my country. Because of the long distance of street lamps, the method of using low-voltage line transmission has huge line loss, and it is a large power consumer of urban public facilities. Solar energy is not only a primary energy source, but also a renewable energy source. It does not require transportation and has no pollution. Therefore, the use of solar street lighting has become an effective means of energy saving and consumption reduction in cities. [0003] ...

AI Technical Summary

Problems solved by technology

However, in harsh environments, the linear control method based on time and light is too simple, and the photosensitive control is easily polluted by dust and rain and snow, resulting in the control method and accuracy of street light switches failing to meet the requirements.
