Description
Technical field
The utility model belongs to solar street light technical field, particularly relates to a kind of solar street light low-light charge control system.
Background technology
Along with the development of society's science and technology, at lighting field, solar street light, as photovoltaic generating system main application model at home, is more and more familiar with and is accepted.In recent years, along with the continuous expansion of China's urban construction scale and improving constantly of its construction level, the total average speed with annual about 20% of street lamp in China city increases progressively, and the economize on electricity problem of tens million of the street lamps in the whole nation has caused the concern of government department.Being becoming tight energy day, today of supply of electric power constant tension, the traditional cities illumination of poor efficiency, high consumption has become energy-saving and cost-reducing key areas.Along with the development of solar energy generation technology, solar street light becomes the new lover of city illumination industry with environmental protection, the advantage such as energy-conservation, and market potential is huge.
Solar power generation is traditionally all utilize the high light of the sun to carry out opto-electronic conversion, if but even can not generate electricity with regard to being difficult to generating when continuing sky the moon, this limits popularization and the use of solar street light within the specific limits, so how making full use of without allowing solar energy continue when sunlight or sky the moon can be exactly key problems-solving for mankind's service.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of solar street light low-light charge control system, efficiently solves the powerup issue of solar street light under continuous overcast sky.
To achieve these goals, the technical solution adopted in the utility model is: a kind of solar street light low-light charge control system, comprise solar panel, low-light compensation control system and storage battery, described low-light compensation control system is by current signal detection circuit, Current calculation circuit, charge storage circuit, shaping circuit, current converter circuit, switching circuit and pulsation circuit connect to form successively, and another output of switching circuit connects the input of charge storage circuit, in order to control the release of electric charge, one output of described solar panel connects current signal detection circuit, be used for transmission current signal, another output of solar panel connects the input of charge storage circuit, be used for stored charge.
As preferably, described shaping circuit is pulse shaper.
The beneficial effect that the utility model takes technique scheme to bring is: the utility model has used the principle of storage cistern in circuit design, run up to by small area analysis and to a certain degree become big current, thus meet the demand of battery charging, the instantaneous break-make of control switch circuit, the electric current of storage can be discharged on request, meet the charging level to storage battery, achieve the object of low-light solar energy compensating charge.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of the utility model solar street light low-light charge control system.
Embodiment
Below in conjunction with accompanying drawing and better embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of solar street light low-light charge control system, comprise solar panel 1, low-light compensation control system and storage battery 2, described low-light compensation control system is by current signal detection circuit 3, Current calculation circuit 4, charge storage circuit 5, shaping circuit 6, current converter circuit 7, switching circuit 8 and pulsation circuit 9 connect to form successively, and another output of switching circuit 9 connects the input of charge storage circuit 5, in order to control the release of electric charge, one output of described solar panel 1 connects current signal detection circuit 3, be used for transmission current signal, another output of solar panel 1 connects the input of charge storage circuit 5, be used for stored charge.
Utility model works process is as follows, if it is high light that current signal detection circuit 3 perceives solar energy, low-light compensation control system does not work, solar panel 1 directly by power storage to storage battery 2, if it is faint light that current signal detection circuit 3 perceives solar energy, it is faint that solar panel 1 produces electric energy, storage battery 2 can not be stored into, now, the spontaneous startup of low-light compensation control system, analog signal is converted to digital signal by current signal counting circuit 4, control solar panel 1 by charge transfer to charge storage circuit 5 simultaneously, when electric charge is higher, switching circuit 8 is opened and is controlled charge storage circuit release electric charge, pulse shaper 6 advanced horizontal pulse adjustment shaping, pulse current is translated into again by current converter circuit 7 conversion, then switching circuit 9 discharges pulse current and is stored into storage battery 2.
Claims (2)
1. a solar street light low-light charge control system, it is characterized in that: comprise solar panel, low-light compensation control system and storage battery, described low-light compensation control system is by current signal detection circuit, Current calculation circuit, charge storage circuit, shaping circuit, current converter circuit, switching circuit and pulsation circuit connect to form successively, and another output of switching circuit connects the input of charge storage circuit, in order to control the release of electric charge, one output of described solar panel connects current signal detection circuit, be used for transmission current signal, another output of solar panel connects the input of charge storage circuit.
