Abstract
The present utility model provides a rapidly awakened set top box upon powering on, and the set top box relates to the set top box technology field. The set top box comprises a set top box master control circuit, a main power supply, a standby power supply and a power supply switching module; the set top box master control circuit is electrically connected with the power supply switching module, and the power supply switching module is respectively connected with the main power supply and the standby power supply. The set top box is characterized in that the set top box is provided with the main power supply and the standby power supply, when the set top box is in the open sate, the main power supply is used for providing electric energy for the set top box, when a television is closed, the main power supply of the set top box is closed, a power supply of the set top box is switched to the standby power supply from the power supply switching module. and the standby power supply is used for supplying power for the set top box master control circuit. Thus, when the set top box is powered off, the state before powering off of the set top box is maintained, the set top box can be used for directly providing digital signals for the television without being awakened when the television is opened again, and users can use conveniently.
Description
[technical field]
The utility model relates to the set-top box technique field, relates in particular to the power supply of STB.
[background technology]
At present; DTV is to realize through the mode that STB receiving remote satellite-signal is transferred to TV, usually, and after TV is closed; The STB power supply is also closed thereupon; When opening TV once more, STB needs long wakeup time to start just can return to the preceding state of shutdown, brings inconvenience to the user.
[utility model content]
The purpose of the utility model needs long wakeup time to user's a kind of STB of starting shooting and waking up fast that deficiency provides of making troubles when being to overcome existing set-top-box opening.
The utility model is realized through following technical scheme: a kind of STB of starting shooting and waking up fast, and it comprises STB governor circuit and main power source, its improvements are that it also comprises standby power and power supply handover module; Said STB governor circuit and said power supply handover module electrically connect, and said power supply handover module electrically connects with said main power source and standby power respectively.
Do further to set forth in the face of above technical scheme down:
Further, said standby power is a storage battery; It also comprises a charging circuit, and the current input terminal mouth of said charging circuit and said main power source electrically connect, and the current output terminal mouth of said charging circuit and said standby power electrically connect.
The beneficial effect of the utility model is: one of which, this STB are provided with a main power source and a standby power, in the STB opening, are that STB provides electric energy by main power source; After TV is closed; The main power source of STB also will be closed thereupon, and at this moment, the power supply handover module switches to standby power with the power supply of STB; At this moment, standby power is the power supply of STB governor circuit; By this, when STB was in off-mode, STB kept the state before the shutdown, and when turning on TV once more, STB need not to wake up promptly directly for TV provides digital signal, and is convenient for users to use; They are two years old; This standby power is a storage battery; The charging circuit that is provided with in the STB provides electric energy through main power source in the set-top-box opening state be the standby power charging, makes that standby power has enough electric energy to supply the STB governor circuit to use after the STB shutdown.
[description of drawings]
Fig. 1 is the circuit frame principle figure of the utility model.
Reference numeral: 1, STB governor circuit; 2, main power source; 3, standby power; 4, power supply handover module; 5, charging circuit.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described:
With reference to shown in Figure 1, the STB that the start of this structure wakes up fast, it comprises STB governor circuit 1 and main power source 2, this STB also comprises standby power 3 and power supply handover module 4; Said STB governor circuit 1 electrically connects with said power supply handover module 4, and said power supply handover module 4 electrically connects with said main power source 2 and standby power 3 respectively.This STB is provided with a main power source 2 and a standby power 3, in the STB opening, for STB electric energy is provided by main power source 2; After TV is closed; The main power source 2 of STB also will be closed thereupon, and at this moment, power supply handover module 4 switches to standby power 3 with the power supply of STB; At this moment, standby power 3 is 1 power supply of STB governor circuit; By this, when STB was in off-mode, STB kept the state before the shutdown, and when turning on TV once more, STB need not to wake up promptly directly for TV provides digital signal, and is convenient for users to use.
Still with reference to shown in Figure 1, standby power 3 is a storage battery; Also comprise a charging circuit 5 in the STB, the current input terminal mouth of said charging circuit 5 and said main power source 2 electrically connect, and the current output terminal mouth of said charging circuit 5 and said standby power 3 electrically connect.This standby power 3 is a storage battery; The charging circuit 5 that is provided with in the STB provides electric energy through main power source 2 in the set-top-box opening state be standby power 3 chargings, makes that standby power 3 has enough electric energy to supply the STB governor circuit to use after the STB shutdown.
According to the announcement and the instruction of above-mentioned specification, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to is in the protection range of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
Claims (2)
1. STB that start wakes up fast, it comprises STB governor circuit and main power source, it is characterized in that: it also comprises standby power and power supply handover module; Said STB governor circuit and said power supply handover module electrically connect, and said power supply handover module electrically connects with said main power source and standby power respectively.
2. the STB that start according to claim 1 wakes up fast is characterized in that: said standby power is a storage battery; It also comprises a charging circuit, and the current input terminal mouth of said charging circuit and said main power source electrically connect, and the current output terminal mouth of said charging circuit and said standby power electrically connect.
