Description

A solar street lamp control device

technical field

The utility model relates to the field of street lamp control, in particular to a solar street lamp control device.

Background technique

A single solar cell cannot be directly used as a power source. As a power supply, several single cells must be connected in series and parallel and tightly packed into components. Solar photovoltaic panels are the core part of the solar power generation system, and also the most important part of the solar power generation system.

Sunlight shines on the semiconductor p-n junction to form new hole-electron pairs. Under the action of the electric field of the p-n junction, holes flow from the n region to the p region, and electrons flow from the p region to the n region. After the circuit is turned on, a current is formed. This is how photoelectric effect solar cells work. Solar power generation Solar power generation is usually a light-to-electricity direct conversion method that uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for light-to-electricity conversion is a solar cell. A solar cell is a device that converts sunlight energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will convert the sun's light energy into electrical energy, generating current. When many batteries are connected in series or in parallel, it can become a solar cell square array with relatively large output power.

Existing street lamps usually use timers or light sensors to control the switch of street lamps. Usually, the street lamps are controlled according to the rising time of the sun in the morning or evening or the weather conditions. Not turning on street lights in weather or dark weather will increase road risk. The use of a timer is very inflexible, and it cannot accurately respond to bad weather; and the light sensor, due to the small area of the sensing element, may cause misjudgment due to dust coverage or insufficient sensitivity, and cannot accurately perceive the intensity of outdoor light.

Moreover, the existing solar street lights are usually equipped with an independent power supply, and the maintenance cost is relatively high. At the same time, due to factors such as the power of solar photovoltaic panels and the high cost of large-capacity batteries, it is generally impossible to use 100% of the stored solar energy to supply power to high-power street lighting. , and in some areas in some seasons, the light is not very sufficient, and it is not suitable to use solar-powered lighting.

Utility model content

In order to achieve this technical purpose, the solution of this utility model is: a solar street lamp control device, including a solar photovoltaic panel, a street lamp, and a control module, and the control module includes a signal collector, a preprocessing module, a digital signal processing module, and an execution drive module, the signal collector, preprocessing module, digital signal processing module and execution drive module are electrically connected through a circuit in turn, the execution drive module is electrically connected to the street lamp, and the signal collector is electrically connected to the solar photovoltaic panel.

Preferably, the control module is also provided with an adjustment module.

Preferably, the adjacent street lamps are also connected with a shared backup battery and communication module.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, the specific embodiment of the utility model is a solar street lamp control device, including a solar photovoltaic panel, a street lamp, and a control module, and the control module includes a signal collector, a preprocessing module, and a digital signal processing module 1. Executing the driving module, the signal collector, the preprocessing module, the digital signal processing module and the executing driving module are electrically connected through a circuit in turn, the executing driving module is electrically connected to the street lamp, and the signal collector is electrically connected to the solar photovoltaic panel . The solar photovoltaic panel is used as a light sensor to judge whether the light is sufficient. Because the area is large and it is not easily affected by local interference, the sensitivity is high. Good stability in use.

In order to facilitate the installer to debug and install, the control module is also provided with an adjustment module. Since the intensity of light in different areas is slightly different, it needs to be set to achieve the best effect.

In order to improve the emergency safety performance, the adjacent street lights are also connected with a shared backup battery and communication module. By sharing backup batteries, maintenance costs can be reduced, and emergency use in special situations can also be guaranteed. The communication module is convenient for controlling street lights in a certain area and improving the operating efficiency of public equipment.

In this application, the solar photovoltaic panels are connected in parallel to the backup battery to form a microgrid. There is no separate battery for each street lamp. Due to the high power of the street lamp, the mains power is used under normal conditions; the solar photovoltaic panel is used as a light sensor. And when there is an abnormality in the municipal power grid, the solar photovoltaic panels and wind power generation modules are used to cooperate with power supply. Or when the sunlight is sufficient in some seasons, the daytime backup battery can also be used to store power for night use. At the same time, a communication module is provided to facilitate the control of the power supply of each area.

Existing solar street lamps use separate batteries for each street lamp and use solar power for power supply. However, due to the effective power of solar photovoltaic panels and high battery maintenance costs, the use of solar photovoltaic panels for energy storage and power supply cannot meet the needs of daily high-power lighting. required and expensive to repair.
