Background technology
Security monitoring at present is more and more important; Therefore the use zone of CCTV (Closed Circuit Television) closed-circuit TV camera is more and more wider; Be installed on indoor CCTV closed-circuit TV camera in the past, and also began to be applied to outdoor environment, crossing or outdoor environment were monitored.
And this type CCTV closed-circuit TV camera generally comprises video camera, and the power supply supply of video camera is the mode that civil power (being generally 220～380 volts, from different places can be different) is converted into direct current through DC adapter.
And because the trend of world's environmental protection and energy saving, can utilize effectively at the energy that to be issued to energy-conservation action be necessary.
Summary of the invention
In view of this, be necessary to provide a kind of supervisory control system of energy savings.
A kind of supervisory control system; It comprises video camera, storage battery and DC adapter; Said supervisory control system further comprises solar cell and PMU; Said PMU comprises controller, first voltage detecting circuit, first switch, second switch and switching circuit; Said DC adapter is connected said video camera to provide electric energy to said video camera through said first switch, storage battery with second switch; Said solar cell is connected said video camera to provide electric energy to said video camera through said switching circuit, storage battery and second switch; The output voltage of the said switching circuit that said controller is used for detecting according to said first voltage detecting circuit judges that whether said solar cell has charging ability to said storage battery and whether the said storage battery that detects according to said second voltage detection unit has enough electric energy to offer said video camera, and the switching that said controller also is used for controlling according to said judged result said first switch and second switch provides electric energy to said video camera through said storage battery power supply to said video camera or said DC adapter to realize said solar cell.
Compared to prior art; The supervisory control system of the embodiment of the invention can be switched between solar cell that adopts environmental protection and energy saving and DC adapter powering mode; DT is arranged; Utilize solar poweredly, DC adapter capable of using of no DT converts civil power into video camera required electric energy and supplies power, thereby can save the energy.

Embodiment
To combine accompanying drawing that the present invention is done further explain below.
See also Fig. 1 and Fig. 2, the supervisory control system 10 of first embodiment of the invention comprises video camera 11, PMU 13, solar cell 14 and DC adapter 15 (DC Adapter).
Wherein, PMU 13 is arranged on and is used in the solar cell 14 realizing the switching between solar cell 14 and the DC adapter 15 so that solar cell 14 or civil power provide electric energy to video camera 11.
Certainly, PMU 13 also can be arranged on the housing of video camera 11 and with solar cell 14 and DC adapter 15 and electrically connect.
The image that video camera 11 is taken shows by display (figure does not show) or is stored in the storage medium (for example, hard disk, CD etc.).
Be provided with the current detection circuit 133 that is connected controller 130 between second switch 136 and the video camera 11, it is used for detecting the electric current that flows in the video camera 11.
Certainly, current detection circuit 133 also can omit.
First voltage detecting circuit 131 that connects controller 130 is set between storage battery 137 and the switching circuit 134; First voltage detecting circuit 131 is transferred to controller 130 with the output voltage of the switching circuit 134 of its detection, and controller 130 is judged the charge condition of 14 pairs of storage batterys 137 of solar cell according to this output voltage; Be provided with second voltage detecting circuit 132 that connects controller 130 between storage battery 137 and the second switch 136, controller 130 is accepted the voltage of second voltage detecting circuit, 132 outputs to judge whether storage battery 137 has enough electric energy to provide video camera 11 to use.
Having under the daylight situation; When controller 130 judges that according to the data of second voltage detecting circuit, 132 inputs storage battery 137 has enough electric energy and judges that according to the data of first voltage detecting circuit, 131 inputs solar cell 14 has charging ability; At this moment; Thereby controller 130 sends controlling signal makes the switch 135 of winning switch to solar cell 14 power supplies with the power supply that second switch 136 cuts off DC adapter 15; So, supervisory control system 10 uses solar cell 14 to supply power can not only reach the effect of environmental protection and energy saving, and solar cell 14 can charge to storage battery 137 simultaneously.
And when arriving night; Controller 130 is learnt according to the magnitude of voltage of first voltage detecting circuit, 131 outputs, though solar cell 14 can't be given supervisory control system 10 to power supply; Learn that by the magnitude of voltage judgement of second voltage detecting circuit, 132 inputs storage battery 137 is having the DT charging; Therefore, supervisory control system 10 can see through storage battery 137 and continued power supply night, up to there being the DT to recover solar cell 14 power supplies again and to the charging action of storage battery 137.
In the supervisory control system 10; Back-up source is made in the path that has also kept DC adapter 15; The electric energy that detects storage battery 137 when second voltage detecting circuit 132 is not enough, and solar cell 14 can not be for storage battery 137 chargings, in order to ensure the normal operation of supervisory control system 10; Controller 130 sends controlling signal makes the switch 135 of winning switch to DC adapter 15 with second switch 136; At this moment, can convert civil power into video camera 11 required voltages through DC adapter 15 and supply supervisory control systems 10 to use, and DC adapter 15 can charge to storage battery 137 simultaneously; Finish or solar cell 14 provides power supply capacity up to storage battery 137 charging, controller 130 just can send controlling signal to switch to solar cell 14 power supplies.
It is understandable that those skilled in the art also can do other variation etc. and be used for design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.These all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
