Abstract
The invention discloses a set top box with an electric power storage function. The set top box comprises a solar module, a central processing unit and a switch circuit, wherein the central processing unit comprises a current detection device and is connected with a television; a control signal is output according to the on and off of the television; the switch circuit selects the solar module or an external power supply to supply power to the set top box according to the control signal; the switch circuit is firstly switched into the solar module when current passes through a power signal cable when the television is turned on; the switch circuit is switched into the external power supply when the solar module displays that the power is not enough; and the switch circuit is communicated with the solar module for electric power storage when no current passes through the power signal cable after the television is turned off. The set top box with the electric power storage function disclosed by the invention can automatically cut off connection with the external power supply when the television is turned off in this manner, and enters a standby mode to store electric power by the solar module. The set top box is convenient to use and saves energy and electricity.
Description
Technical field
The present invention relates to the electronic product field, particularly relate to a kind of set-top box with storage function.
Background technology
At present the digital television that uses of family generally adopts top box of digital machine to add the square same form of television set, and top box of digital machine and television set carry out switch by shift knob separately respectively and control.The user watching or during the closing television machine, then needs respectively to have brought inconvenience manually to set-top box and TV power on and off.And the user has forgotten the power supply of closure plane top box usually behind the closing television machine, thereby causes the waste of power supply.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of set-top box with storage function, can automatic selection circuit.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the set-top box with storage function is provided, comprise: solar energy module, CPU and switching circuit, described CPU comprises current sensing means, wrapping described CPU is connected with television set, according to TV power on and off output control signal, described switching circuit selects solar energy module or external power source that set-top box is powered according to control signal, when having electric current to pass through during television boot-strap on the power signal line, switching circuit at first switches to solar energy module, when the solar energy module electric weight is not enough, switching circuit switches to external power source, when no current passed through on the power signal line during television set shutdown, switching circuit was connected solar energy module and is carried out electric power storage.
In a preferred embodiment of the present invention, described switching circuit has the free end that is connected with external power source holding wire, solar energy module respectively.
In a preferred embodiment of the present invention, the top of described set-top box is coated with solar panel, uses solar energy is converted to electric energy and storage.
The invention has the beneficial effects as follows: the set-top box that the present invention has a storage function can be cut off when television set shuts down and being connected of external power source automatically, enters simultaneously standby mode and adopts solar energy module to carry out electric power storage, and is easy to use, energy saving.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of a kind of set-top box with storage function of the present invention;
Fig. 2 is the structural representation that a kind of set-top box with storage function of the present invention is connected another kind of circuit;
The mark of each parts is as follows in the accompanying drawing: 1,7, power supply, and 2, television set, 3, CPU, 4, switching circuit, 5, solar energy module, 61,62, circuit, 8, set-top box.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 and Fig. 2, the embodiment of the invention comprises:
A kind of set-top box 8 with storage function comprises: solar energy module 5, CPU 3 and switching circuit 4.A kind of set-top box 8 with storage function is connected to television set 2 with external power source 7, and television set 2 has external power source 1, and CPU 3 has current measuring element, detects the electric current on television set 2 power signal lines.
A kind of have storage function set-top box 8 and have solar energy module 5, CPU 3 and switching circuit 4.CPU 3 is used for judging according to the electric current on television set 2 power signal lines that detect whether television set 2 shuts down, and the output control signal.Switching circuit 4 is used for selecting solar powered module or external power source holding wire that set-top box is powered according to control signal.
When having electric current to pass through on the power signal line when television set 2 start, switching circuit 4 at first switches to solar energy module, forms circuit 61, and when the solar energy module electric weight was not enough, switching circuit 4 switched to external power source.
See also Fig. 2, form circuit 62, when no current passed through on the power signal line during television set 2 shutdown, switching circuit 4 was connected solar energy modules 5 and is carried out electric power storage.
The set-top box that the present invention has a storage function can be cut off when television set shuts down and being connected of external power source automatically, enters simultaneously standby mode and adopts solar energy module to carry out electric power storage, and is easy to use, energy saving.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
