Along with the progressively consumption of fossil energy, energy crisis represents in face of the mankind.Crisis is pressing especially for the energy resources reserves situation of China, and except that solar energy, the various disposable energy of China all are lower than world average level, and the energy demand of China is faced with more serious challenge.
China is populous nation, and is big especially to the electric power energy demand, though China's engineerings such as progressively realization is transferred electricity from the west to the east at present, western gas east is sent, it is huge that engineering drops into, and the cycle is long, and also is the consumption of natural energy resources.So,, should strengthen this inexhaustible utilization efficiency of energy of solar energy for the energy present situation of present China.
Various outdoor Play Systems, the Play System that adopts as the mobile TV on outdoor billboard, the automobile (also claiming mobile media), bus shelter, newsstand etc. is display substantially, its energy consumption comes from electric power and carries, the outdoor Play System in city has consumed a large amount of electric power resources, and the disposable just consumption-type energy of these resources.
In order to solve the technical problem that the open urban Play System consumes electric power energy in the prior art, special proposition the present invention.
Summary of the invention
The objective of the invention is deficiency, a kind of Play System that can utilize solar photovoltaic generation system that electric power resource is provided is provided at the prior art existence.
For achieving the above object, the technical scheme of photovoltaic power generation broadcast system provided by the present invention is: a kind of photovoltaic power generation broadcast system, comprise display unit, described display unit is connected with photovoltaic generating system, described photovoltaic generating system comprises photovoltaic battery panel, controller and the inverter that connects successively, controller also is connected with batteries, includes main circuit board, dsp chip, charge-discharge control circuit and fin in the described controller.
Described inverter is arranged in the controller.
Described photovoltaic battery panel can replace with the photovoltaic battery pack.
Described display unit is outdoor electronic bill-board or automobile mobile display, perhaps is the display that is used for bus shelter, or for being used for the display of newsstand.
The invention has the beneficial effects as follows: the present invention utilizes the photovoltaic generation principle with the direct generation of electricity mode of solar radiation power conversion for electric energy, for a large amount of display unit in the existing city provides electric power, environmental protection and energy saving, and the consumption of having saved natural resources in a large number, have higher actual application value and promotional value.
