Description

Bus sign solar power supply system

technical field

The invention relates to the technical field of power supply for bus road signs, in particular to a solar energy power supply technology for bus road signs. the

Background technique

As an important tool in the city, the bus plays a huge role in the convenience of travel. People judge the bus line number, driving direction, starting and ending stations through the information on the front road sign, side road sign and rear road sign on the bus. Name and other ride service information. No matter day or night, buses have to work, and road signs are in a working state of providing information for passengers all the time, which consumes a lot of power for a long time. At present, the power supply of urban bus signs comes from the vehicle itself, and the engine drives the generator to supplement the battery with electric energy. This working method consumes fuel, pollutes the environment, and is prone to noise. the

Contents of the invention

The object of the present invention is to overcome the above-mentioned technical problems, and provide an energy-saving and environment-friendly, reasonable structure, and easy-to-use solar-powered bus sign power supply system. the

In order to achieve the above object, the present invention is achieved through the following technical solutions. the

Solar power supply system for bus signs, including solar panels, DC/DC converters, solar controllers, batteries and brackets; solar panels are installed on the roof of the bus through brackets; solar panels are connected to batteries through solar controllers; DC The input end of the /DC converter is connected to the solar panel, and the output end is connected to the storage battery; the storage battery is connected to the road sign. the

The street sign is composed of front street sign, side street sign and rear street sign. the

The solar battery panel is installed on the roof of the bus and forms an inclination angle of 30-60 degrees with the roof. the

Fig. 2 is a structural schematic diagram of the present invention. the

In the figure: 1 is a solar panel, 2 is a storage battery, 3 is a solar controller, 4 is a DC/DC converter, 5 is a road sign, 6 is a bracket, and 7 is a roof. the

Detailed ways

In order to make the purpose, technical solution and creative features of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. the

As shown in Figure 1 and Figure 2, the solar energy power supply system for bus signs includes a solar panel 1, a DC/DC converter 4, a solar controller 3, a storage battery 2 and a bracket 6; the solar panel 1 communicates with the solar controller 3 The battery 2 is connected; the input end of the DC/DC converter 4 is connected to the solar panel 1, and the output end is connected to the battery 2; the battery 2 is connected to the street sign 5. The road sign 5 refers to the electronic bus sign. The road sign 5 is composed of the front sign 5, the side sign 5 and the rear sign 5. Their working voltage is the same, so only the same power supply is needed to meet their needs. The bracket refers to the hole that is convenient for laying wires inside. The solar panel 1 is installed on the roof 7 of the bus through the bracket 6 and is at an inclination angle of 30-60 degrees with the roof 7. The purpose is to receive sunlight to the maximum extent. and convert the light energy into electric energy. When the power generation is greater than the electric energy required by the street sign 5, the solar panel 1 charges the battery 2 with the excess electric energy through the solar controller 3, and the electric energy is stored in the battery 2. DC/DC converter 4 includes: Buck Converter, Boost Converter and Buck–Boost Converter. In continuous rainy weather, The solar energy is particularly weak, and when the electric energy of the battery 2 cannot meet the electric energy required by the street sign for continuous working days, the electric energy converted by the solar panel 1 is adjusted by the DC/DC converter 4, and the adjusted electric energy and the electric energy of the battery 2 are simultaneously The street sign 5 supplies power, which ensures the normal operation of the street sign, and at the same time prevents the battery 2 from being over-discharged and impairing its service life. the
