technical field

The utility model belongs to the application field of solar energy, in particular to a networked centralized control system for dual power supply solar traffic signal lamps.

Background technique

Solar power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. Photovoltaic effect, referred to as "photovoltaic effect", refers to the phenomenon that light causes a potential difference between different parts of an inhomogeneous semiconductor or a combination of semiconductor and metal. It is firstly the process of converting photons (light waves) into electrons and light energy into electrical energy; secondly, it is the process of forming voltage. With voltage, it is like building a high dam. If the two are connected, a current loop will be formed. The advantage of photovoltaic power generation is that it is less restricted by region, because the sun shines on the earth, and the photovoltaic system also has the advantages of no noise, low pollution, no need to consume fuel and erect transmission lines, and it can generate electricity and supply power on site, and the construction period is short.

It is a common technology to use the solar power generation system to charge the battery with energy storage. After the traditional solar energy is converted from light energy to electric energy, the battery is charged through the solar controller, or the electric energy is supplied to the AC load after passing through the solar controller and inverter. , or the solar panel directly supplies power to the DC load. At present, the solar energy used on the market charges the battery. After the battery is fully charged, as long as the user does not cut off the input power of the charger, the charger will continue to charge the battery, which will shorten the life of the charger. The service life of the charger increases the failure rate of the charger, which is likely to cause other unsafe accidents. When stopping solar energy to charge the battery, the connection between the charging controller and the solar panel should be disconnected first, and then the connection between the charging controller and the battery should be disconnected. Otherwise, it is easy to cause charger failure. Also there is the shortcoming of wasting electric energy in the prior art.

At the same time, once the voltage of the solar panel is lower than the voltage of the battery, the charging process will stop until the power of the solar panel is restored. In daily life, due to the constant change of light, the charging of the battery is also extremely unstable. If the charging is too frequent, it is easy to reduce the life of the battery and greatly reduce the charging efficiency. Due to the above shortcomings, solar-charged storage batteries cannot be widely used in various fields, which limits the progress of science and technology.
