Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the network machine top box energy-saving control device that provides of the utility model embodiment;
Fig. 2 is the circuit diagram of control circuit;
Fig. 3 is the circuit diagram of indicating circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The schematic diagram of network Set Top Box energy-saving control device as shown in Figure 1, the network machine top box energy-saving control device that the utility model embodiment provides comprises:
Switching circuit 1, generates high level or low level for triggering;
Control circuit 2, for receiving the output level of described switching circuit, and corresponding control closed or output services voltage.
During standby switches in trigger switch circuit 1, switching circuit 1 output low level, control circuit 2 disconnects, and Set Top Box power module does not have voltage input, enters holding state, reaches energy-conservation object; When again triggering standby switches, switching circuit 1 output high level, control circuit 2 is connected, Set Top Box power module input service voltage, Set Top Box is normally worked.Therefore the utility model embodiment by switching circuit is set, control circuit reaches the object that reduces set-top box standby energy consumption.
During specific implementation, as shown in Figure 2, described control circuit 2 comprises triode Q2 and metal-oxide-semiconductor Q14, described switching circuit output is connected to the base stage of triode Q2 by resistance R 30, and base stage is by resistance R 24 ground connection, the grounded collector of triode Q2, the emitter of triode Q2 is pulled to power supply by resistance R 29, and between the grid of the emitter of triode Q2 and metal-oxide-semiconductor Q14, be also provided with resistance R 43, the source electrode of described metal-oxide-semiconductor Q14 is connected to power supply, the drain electrode of metal-oxide-semiconductor Q14 is as the operating voltage output of network machine top box, a voltage-stabiliser tube also in parallel between the source-drain electrode of described metal-oxide-semiconductor Q14.
Output low level after switching circuit is triggered, because Q2 launches very high level, so Q2 cut-off, between the grid source electrode of Q14, voltage is less than the cut-in voltage of metal-oxide-semiconductor, and Q14 ends equally, so the drain electrode of Q14 do not have Voltage-output, and Set Top Box enters holding state.
When switching circuit is subject to triggering again, export high level, the base voltage of Q2 is higher than emitter voltage, and Q2 conducting, has electric current to pass through on R43, and between the grid source electrode of Q14, voltage is greater than the cut-in voltage of metal-oxide-semiconductor.Now Q14 conducting, so the drain electrode output services voltage of Q14, the modules power supply for Set Top Box, enters normal mode of operation.
Therefore by above-mentioned control circuit, can realize set-top box standby and control.
As a kind of preferred implementation, described in state metal-oxide-semiconductor Q14 drain electrode also by two capacitor C in parallel 6, C10, be connected to ground.By capacitor C 6, C10, can reach the object of filtering output services voltage noise, with burning voltage, export.
In addition, as shown in Figure 3, the output of described switching circuit is also connected with indicating circuit 3, described indicating circuit comprises green light D17 and red light D16, the output of switching circuit is connected to ground by resistance R 9, green light D17 successively, and the output of Simultaneous Switching circuit is connected to ground by reverser D15, resistance R 22, red light D16 successively.When switching circuit is triggered output low level, green light D17 extinguishes, and low level becomes high level after reverser D15, and red light D16 is bright, and indication Set Top Box enters holding state; When switching circuit is triggered again, export high level, green light D17 is bright, and red light D16 extinguishes, and indication Set Top Box is normally worked.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
