Self-adjustment solar street lamp controller

Abstract

The invention discloses a self-adjustment solar street lamp controller, and the controller comprises an LED light-emitting module, an LED drive circuit, a storage battery pack, a solar cell, a DC-AC step-up circuit, a DC-DC step-down circuit, a Zigbee module, and a control module. The control module comprises a single-chip microcomputer, and the single-chip microcomputer is used for communication and data transmission with the Zigbee module. The single-chip microcomputer is connected with a charging end of the storage battery pack, and is used for controlling the on / off of charging, solving the integration of a charging current, and obtaining a charging quantity serving as a correcting factor. The single-chip microcomputer collects the voltage and temperature of a battery of the storage battery pack, and is used for monitoring the battery in real time, and protecting the battery from being overcharged. The single-chip microcomputer solves the internal resistance of the battery through monitoring the open-circuit voltage of the storage battery pack, and obtains the initial electric quantity of the battery, wherein the initial electric quantity is used for calculating the remaining electric quantity. The single-chip microcomputer controls the brightness of a lamp through a PWM signal, and achieves a purpose of adaptive adjustment of brightness.

Description

technical field [0001] The invention relates to the field of street lamp control devices, in particular to a self-adjusting solar street lamp controller. Background technique [0002] Solar street lights have been widely recognized for their advantages of no need to lay cables and no consumption of conventional energy. However, there are still some problems in solar street lamps, which cause their high cost and unstable reliability. For example, batteries often need to be replaced in less than a year, which not only increases the cost of later maintenance, but also increases the consumption cost of customers and causes a waste of resources. Secondly, solar energy is an unstable energy source, and the energy distribution is uneven. In summer, the energy is sufficient, but the street lamps are used for a short time. In winter, the effective illumination time is short, but the street lamps are used for a long time, which greatly reduces the reliability of operation. controlle...

AI Technical Summary

Problems solved by technology

However, there are still some problems in solar street lamps, which cause their high cost and unstable reliability.

For example, batteries are often replaced in less than a year, which not only increases the cost of later maintenance, but also increases the consumption cost of customers and causes waste of resources.

Secondly, solar energy is an unstable energy source, and the energy distribution is uneven. In summer, the energy is sufficient, but the street lamps are used for a short time. In winter, the effective illumination time is short, but the street lamps are used for a long time, which greatly reduces the reliability of operation. controller impact

[0003] Most of the solar street lamp controllers on the market use single-chip microcomputer control, which has the disadvantages of high cost, cumbersome development, and high loss. At the same time, it will be affected by the insufficient energy storage of the battery power supply caused by unstable weather.
