Abstract
The disclosed method for low power consumption standby comprises: a signal emission module to generate IR signal, a signal process module with a detection circuit module for pyre-IR-ray to detect surrounding environment and generate control signal, and a power module to enter standby state or normal state according to control signal. When user leaves away, the detection circuit module finds no IR signal, sends standby control signal to the power to make it standby; when user returns, the detection circuit finds micro-IR signal from people and sends signal to enable it enter normal state. This invention is benefit to save power energy.
Description
[technical field]
The present invention relates to the consumption electronic products technical field, particularly a kind of method that realizes Digital Television, digital television receiver low-power consumption standby.
[background technology]
Be accompanied by coming at the appointed time of digital tide, countries in the world start the integral body conversion of simulated television to Digital Television comprehensively, and from China's Digital Television development process table, digital television, digital television receiver will promptly be come into huge numbers of families.In digital television receiver is used, if a user is when TV reception, go to the parlor to have a meal, perhaps to help to share housework, or be in a hurry suddenly will handle or the like and leave television set, thisly can not estimate to spend under the situation how long, the user can not closed digital television receiver and Digital Television, because most users have such psychological factor, promptly will return at once, yet true really not so, this certainly will waste a large amount of electric energy, so be necessary to study a kind of method that realizes low-power consumption standby.
[summary of the invention]
For addressing the above problem, main purpose of the present invention is to provide a kind of method that realizes Digital Television, digital television receiver low-power consumption standby.
In order to realize above-mentioned technical problem, the technical solution used in the present invention is:
A kind of method that realizes low-power consumption standby comprises the steps:
A. provide signal emission module, to produce the thermal infrared signal;
B., signal processing module is provided, and it includes pyroelectric infrared detection circuit module, to survey surrounding environment thermal infrared RST, produces the Opportunity awaiting control for linear signal;
C., the standby power module is provided, and its Opportunity awaiting control for linear signal that produces according to signal processing module enters holding state or start normal condition.
Compared to prior art, the present invention realizes that the method for low-power consumption standby by pyroelectric infrared detection circuit module detection surrounding environment thermal infrared RST, produces the Opportunity awaiting control for linear signal, with the ideal case of control standby power module; When the user left, heat was released the infrared acquisition circuit module and is surveyed less than infrared signal, sent Opportunity awaiting control for linear signal to standby power module and made it enter holding state; When the user returned, heat was released little infrared signal that the infrared acquisition circuit detects the human body emission, sent the Opportunity awaiting control for linear signal to the standby power module, made the standby power module finish holding state, and entered the start normal condition.Thereby be user-friendly to saves energy.

[embodiment]
Please refer to shown in Figure 1, a kind of method that realizes low-power consumption standby, motherboard circuit module, the signal processing module of the set-top box that comprise the standby power module, links to each other and the signal emission module that is connected signal processing module with the standby power module.Wherein, signal processing module comprises pyroelectric infrared detection circuit module and front panel display module; In this creation, the human body of signal emission module for moving.Pyroelectric infrared detection circuit module is surveyed the low-grade fever infrared signal that human body produces, and sends the Opportunity awaiting control for linear signal according to the result who surveys to the standby power module, and the standby power module enters holding state or start normal condition according to this Opportunity awaiting control for linear signal.
Please refer to shown in Figure 2, when the user will leave because of special situation in the TV reception process, when also not closing digital television receiver and Digital Television, heat is released infrared sensor and is surveyed less than the low-grade fever infrared signal, the pin PIN2 of IC001 recovers high level, and triode Q001 ends.At this moment, the continuation conducting of field effect transistor Q002 is still kept in capacitor C 003 discharge.But along with the decline that triode C003 goes up voltage, field effect transistor Q002 enters the amplification region until cut-off region by the saturation region, is output as high level, and the standby power module receives the high level signal of STBY output, allows the power supply standby.Simultaneously, regulate resistance R 002, according to T=RC, i.e. scalable stand-by time can realize that how long the people leaves behind the television set, just carries out the action of standby.The user returns again after a period of time, and heat is released infrared sensor and detected signal emission module human body just, the low-grade fever infrared signal of emission, the pin PIN2 output low level of IC001, triode Q001 conducting.Vcc is through triode Q001, and diode D002 gives capacitor C 003 charging, along with the rising that triode C003 goes up voltage, and the rapid saturation conduction of field effect transistor Q002, STBY is output as low level, and digital television receiver and Digital Television enter normal operating conditions.
Please refer to and Figure 3 shows that standby power module drawing with SKIP CYCLE (batch (-type)) pattern, release the infrared induction detection circuit when heat and provide an Opportunity awaiting control for linear signal, be that STBY is when being output as high level, triode Q651 and triode Q652 conducting, because 5V STBY receives the feedback end of TL431, light idol feedback current strengthens, and duty ratio is dragged down, and makes that the voltage of 5V STBY port is to maintain 5V all the time.But because the output voltage of original 60V is adjusted to 5V output, make the duty ratio of switch become more much smaller,, approximately be compressed 12 times, all export the power that consumes this moment and diminish so other all output voltages also becomes very little than in the past.Under this standby mode, light idol feedback becomes very heavy, make the feedback voltage of IC601 be lower than set point, IC601 promptly enters the mode of operation control of a kind of SKIPCYCLE of being referred to as, the system device stops output drive signal according to the big or small batch (-type) ground of power output but the maintained switch frequency is constant, can reduce stand-by power consumption to a great extent like this.All output under SKIP CYCLE mode of operation comprises that the IC power supply all descends, and many single-chip power supply IC keep the power supply of self by inner self-powered circuit, make the loss of whole power supply reduce greatly.Digital television receiver and Digital Television are in the environment of a green power supply like this, and standby power is less than 0.5W.
Release the infrared induction detection circuit when heat and provide a start control signal, when promptly STBY was output as low level, triode Q651 and triode Q652 ended, and digital television receiver and Digital Television are in normal mode of operation.
Most preferred embodiment described above only is that this creation is set forth and illustrated, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
