A photovoltaic power generation system that supplies power to a Beacon base station through a photoelectric conversion device using light energy. The light intensity of the store is basically higher than the natural light intensity, so it can provide a stable source of power for the base station.

The following describes the working principle of the photoelectric conversion process. The photoelectric conversion process is a photon that transfers energy to an electron to move it to form a current. There are two solutions to this process. The most common one is to use a solid device with a semiconductor material as the main material, and the other is to use photoactive dye molecules to capture the energy of photons.

FIG. 1 is a schematic diagram of a photovoltaic power generation system for powering a Beacon base station according to the present invention. As shown in FIG. 1 , the photovoltaic power generation system for powering a Beacon base station includes a photoelectric conversion device 100 and a photovoltaic controller 200 current converter. 300 and Beacon base station 400.

The photoelectric conversion device 100 is electrically connected to the photovoltaic controller 200 for converting light energy in the working environment of the Beacon base station into electrical energy.

The photoelectric conversion device can be, for example, a photovoltaic module, which is a material device that converts solar energy into electrical energy by a photovoltaic effect, which is obtained by sealing a solar cell of different specifications. Existing photovoltaic module types are monocrystalline silicon, polycrystalline silicon, amorphous silicon, and diversified photovoltaic modules. In a preferred embodiment of the present invention, the photovoltaic module uses an amorphous silicon photovoltaic module, which belongs to a novel thin film type solar cell, which has less silicon consumption and lower cost. The amorphous silicon photovoltaic module used in the utility model mainly considers that it can generate electricity under various light intensity environments, and can adapt to different strengths of visible light sources in a public place (such as a shopping mall) where the Beacon base station is located.

Further, in a preferred embodiment of the present invention, the photovoltaic module is composed of a plurality of solar cells connected in series or composed of a plurality of solar cells in parallel or a plurality of solar cells connected in parallel.

The input end of the current converter 300 is electrically connected to the photovoltaic controller 200;

In a preferred embodiment of the present invention, an analog/digital circuit connection can be employed between the photovoltaic module, the photovoltaic controller, and the current converter to ensure stable energy transfer.

As described above, the present invention provides a photovoltaic power generation system for powering a Beacon base station, which converts light energy in a working environment of a Beacon base station into electrical energy by a photovoltaic module, and passes through a photovoltaic controller and a current converter. Continuous power supply to the Beacon base station after conversion can not only avoid the loss caused by manual disassembly and replacement of the battery to the Beacon base station, but also prolong the service life of the Beacon base station.

The technical solution of the present invention will be described in detail below with reference to specific embodiments. In this embodiment, the Beacon base station is located in a large-scale shopping mall, and the photoelectric conversion device is an amorphous silicon photovoltaic component in a photovoltaic power generation system that supplies power to the Beacon base station.

Specifically, the amorphous silicon photovoltaic component converts light energy in the working environment of the Beacon base station into electrical energy and outputs it to the photovoltaic controller. During the business hours of the mall, the light energy in the working environment of the Beacon base station is sufficient, the Beacon base station is in working state, and the amorphous silicon photovoltaic module continuously converts the light energy in the working environment of the Beacon base station into electric energy. During the non-business hours of the mall, the optical energy in the working environment of the Beacon base station is insufficient, and the amorphous silicon photovoltaic module cannot convert the light energy in the working environment of the Beacon base station into electrical energy. Therefore, the Beacon base station is in a non-working state at this time. That is to say, compared with the prior art method of supplying power to the Beacon base station through the battery, the power supply in the present invention can cut off the power supply during non-business hours and prolong the working life of the Beacon base station.

The photovoltaic controller processes the electrical energy output from the amorphous silicon photovoltaic module. The photovoltaic controller is an automatic control device that controls the solar cell array to charge the battery and the battery to supply the solar inverter load. Photovoltaic controllers typically have six nominal voltage levels: 12V, 24V, 48V, 110V, 220V, 500V. By using innovative maximum power tracking technology, the PV controller can guarantee the full range of light energy battery arrays throughout the day and all weather. Efficiency work. PV module efficiency can be increased by 30% (average efficiency can be increased by 10%-25%). In this embodiment, the photovoltaic controller has a nominal voltage rating of 12V.

The DC/DC current converter is a voltage converter that effectively outputs a fixed voltage after converting the input voltage. The switching power supply device is a converter that continuously stores/discharges through the inductor and finally reaches a stable voltage/current output. Because the current standard output voltage of the PV controller is at least 12V, which exceeds the rated voltage when Beacon is working. In this embodiment, the standard output voltage of the photovoltaic controller is 12V, and the rated voltage of the Beacon base station when operating is 3V. Therefore, the current converter in this embodiment is a step-down DC/DC current converter, which will be photovoltaic. The power output of the controller is voltage-converted, and the voltage-reducing current converter converts to a rated voltage of 3V when the Beacon base station operates, thereby providing a stable DC power supply for the Beacon.

The communication component of the Beacon base station is the external communication module of the Beacon base station, and is also the main consumption module, and the component module for transmitting the Bluetooth signal. Among the current mainstream products, Beacon works best when the transmission power is +4dBm and the broadcast interval is 100ms. At this time, a 500mAh battery can supply power to the base station for 3 to 6 months. The photovoltaic controller and the current converter in this embodiment can continuously provide a rated 3V voltage and a rated current of 5 to 30 uA for the communication component.

As described above, the utility model provides a photovoltaic power generation system for supplying power to a Beacon base station, and the photovoltaic component converts light energy in the working environment of the Beacon base station into electric energy, and is converted by the photovoltaic controller and the current converter. The Beacon base station continues to supply power. By using the optical energy in the working environment of the Beacon base station to continuously supply power to the base station, it can not only avoid the loss caused by the manual disassembly and replacement of the battery, but also can synchronize with the store business hours and prolong the service life of the base station.

Compared with the traditional manual battery replacement method, the light energy power supply method of the utility model has the following advantages:

1. Reduce the labor cost and accidental loss of battery replacement:

The power supply can effectively extend the maintenance cycle and reduce the labor cost of replacing the battery. At the same time, since the Beacon base station is a sophisticated device, accidental loss may occur during battery replacement, and the power supply can effectively reduce such loss.

2. Synchronize with the business hours of the merchants and extend the service life of the base station:

When the mall is not open, if the Beacon base station is still working, it will not only waste Beacon's work efficiency, but also reduce the service life of the Beacon base station. The power supply can cut off the power during non-business hours and extend the working life of the Beacon base station.

3. Reduce waste battery generation and environmental pollution:

Another advantage of using light energy to supply power is environmental protection. The use of light energy can effectively reduce the generation of used batteries, and is a new environmentally friendly and clean energy source.
