Description
Technical field
The utility model relates to a kind of solar DC photovoltaic generating system, particularly a kind of mobile TV solar DC photovoltaic generating system.
Background technology
The maximum feature of mobile TV is: be in mobile status, on the vehicles that speed per hour is less than 120 kilometers, keeps the stable and clear of TV signal, make spectators can in mobile status TV reception easily.Mobile TV is the same with broadcast, all uses the method for wireless signal transmission and ground receiver.The place that present mobile TV uses at most is exactly public transport TV, the broad covered area of public transport TV, be swift in response, mobility is strong, contact frequency is high, makes people can obtain information timely.Communication effect refers to the activity of the activities of transmission especially mass media such as newpapers and periodicals, broadcast, TV, all generation by biography person and society are affected and result comprehensive, no matter these impacts be have a mind to or unintentionally, directly or indirectly, show or potential.Mobile TV is as emerging media, necessary beyond doubt to the analysis of its communication effect.
At present, existing mobile TV occupation rate of market is low, and mobile TV majority is hand-held rechargeable, also some use is solar powered, but this solar photovoltaic generation system is generally residents, powers also will to except television set other household electrical appliance, it is converted into direct current energy solar energy and is stored in storage battery, also will carry out boosting inversion process, the DC conversion that storage battery is exported is the alternating current of 220V, uses for various household electrical appliance.Owing to there being boosting inversion link, the loss ratio of this solar photovoltaic generation system is higher, and efficiency is not very high, and too increases production cost.Have for some grassland ecological of China again, because people often move, this electricity generation system is also not suitable for.
Summary of the invention
The utility model technical issues that need to address are to provide removable and reliable and stable mobile TV solar DC photovoltaic generating system.
For solving above-mentioned technical problem, mobile TV solar DC photovoltaic generating system of the present utility model comprises solar cell, single-chip microcomputer and storage battery, described solar cell is connected with single-chip microcomputer phase input by an A/D sampling unit, and described single-chip microcomputer output is connected with solar cell; Described single-chip microcomputer output is connected with storage battery by charge-discharge control unit, and described storage battery is connected with single-chip microcomputer input by the 2nd A/D sampling unit; Also comprise mobile TV, described mobile TV is connected with driver element, and described driver element is connected with single-chip microcomputer input by current detecting unit, and described single-chip microcomputer output is connected with driver element.
Further, also comprise temperature sensor, described temperature sensor is connected with single-chip microcomputer input by the 3rd A/D sampling unit.
After adopting said structure, what the utility model was powered to mobile TV through Single-chip Controlling is also direct current, internal system does not have inversion link, it is all relatively simple DC-DC conversion, which reduce internal system electric energy loss, whole system is completely independent simultaneously, highly integrated, without the need to dismounting, mobility is strong.
