Solar street lamp-based intelligent management system for urban illumination

Abstract

The invention belongs to the field of urban illumination, and particularly relates to a solar street lamp-based intelligent management system for urban illumination. The solar street lamp-based intelligent management system for urban illumination comprises a solar panel, a storage battery, a charge control circuit, an automatic sun-chasing device, a street lamp, a master controller, a monitoring center, a cloud center and a user platform, wherein the charge control circuit is connected between an output end of the solar panel and an input end of the storage battery; the automatic sun-chasing device is connected with the input end of the solar panel; the street lamp is connected with the output end of the storage battery; the output end of the master controller is connected with the charge control circuit, the automatic sun-chasing device and the monitoring center respectively; the monitoring center transmits data obtained from the master controller to the cloud center through a GPRS signal; and a GPRS communication mode is adopted by the user platform and the cloud center. Real-time monitoring and management for an illuminating system and the street lamp are achieved by an internet of things and a cloud platform; efficient and stable all-weather operation is ensured; unnecessary 'complete night-light illumination' is controlled; the daily turn-on / off time is adjusted according to the sunrise / sunset time; and the brightness of each lamp is adjusted, so that electric energy is effectively saved.

Description

technical field [0001] The invention belongs to the field of urban lighting, in particular to an intelligent management system for urban lighting based on solar street lamps. Background technique [0002] It has been determined that the solar energy irradiated on the earth for about 40 minutes is enough for the energy consumption of human beings all over the world for one year. Therefore, solar energy as a renewable green energy source is truly inexhaustible and inexhaustible. Solar energy has become one of the most important new energy sources in the 21st century due to its advantages of being renewable, clean and pollution-free, and highly safe. Urban lighting is an indispensable public facility in people's daily life, and the power consumption of urban lighting accounts for about 16% of the total power consumption. Facing the tense power supply situation and the many shortcomings of traditional electric lighting street lamps, solar street lamps will be rapidly populariz...

AI Technical Summary

Problems solved by technology

At present, batteries in solar street light controllers on the market mostly use constant current charging method and constant voltage charging method. This unreasonable charging and discharging control method will easily lead to battery damage, and the internal electrochemical reaction of the battery is greatly affected by temperature. , these factors shorten the life of the battery, thereby shortening the life of the solar street light

[0004] The existing street lamp control schemes mainly include two methods: light control and time control. Due to technical limitations, a single light control or time control method is often used.

When the sunlight is sufficient during the day, the voltage of the battery panel is high, and when the sun sets in the evening, the voltage of the battery panel decreases. When the voltage is low to a certain value, the street lamp is turned on, but the voltage of the battery panel is affected by factors such as the environment or electromagnetic waves. Will change, resulting in street lights may not light up when night falls, that is, the disadvantage of the light control method is that it may cause misoperation

The main disadvantage of the time control method is that it does not consider the influence of the weather on the illuminance, resulting in unreasonable phenomena such as severe insufficient illuminance in rainy days but no lights.

[0005] Traditional solar street lamps are not flexible and intelligent enough in terms of management mode. They only consider energy saving, without platform functions, and cannot provide a variety of intelligent services. For municipal departments, management, inspection, maintenance, etc. still need It consumes a lot of manpower and material resources, and the work efficiency is low

[0006] Although there are currently more than 300 large and medium-sized cities using modern solar street lamp intelligent control systems, which have improved the social and economic benefits of road lighting to a certain extent, but these intelligent systems can only achieve basic functions, such as monitoring vehicles. Traffic can be used to adjust the brightness of street lamps, but it is not flexible enough in remote monitoring and control, and cannot meet the increasing demand for intelligence
