Embodiment
In order that technical problems, technical solutions and advantageous effects to be solved by the present invention are more clearly understood, below in conjunction with
Drawings and Examples, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
With reference to Fig. 1,2, based on the standby controlling method of RF4CE modules 101, comprise the following steps：
Step S110, when RF4CE modules 101 receive start guidance command, then output pulse signal.Specifically, in this reality
Apply in example, output pulse width is, for example, by set top box after its RF4CE module 101 reception start guidance command in holding state
10ms or 15ms or 20ms pulse signal, the pulse signal is input to control module 102 by a PIO mouth 01 of often powering
In.Actually, it is to simulate current infrared receiving module in start remote control life after RF4CE modules 101 receive start guidance command
Exported after order it is standby in the recognizable pulse signal of control module 102 so that it middle wakes up from standby.In the present embodiment, control
Molding block 102 is the master chip of set top box, single-chip microcomputer.
Preferably, above-mentioned pulse signal is low level pulse signal；In other embodiments, the pulse signal can be with
It is high level pulse signal.
Step S120, control module 102 passes through an often reception pulse signal of power supply PIO mouths 01, and control power supply 103
Connect.Specifically, in the present embodiment, the PIO mouths 01 of control module 102 are received after the pulse signal for standby wakeup, in PIO
Mouth 03 (is specifically POWER_CTRL pins：System power supply 103 controls PIO mouthful) low and high level that exports controls to switch on power
103, mutually switch between low-power consumption standby pattern and normal work so as to realize.
Step S130, when the RF4CE modules 101 receive standby guidance command, then exports standby command.Specifically, exist
In the present embodiment, set top box is in open state, and its RF4CE module 101, which is received, will export standby command after standby guidance command,
The standby command is input in control module 102 by a serial ports.Serial ports is that two very PIO mouthfuls of power supplies are combined, such as
It is made up of PIO mouths 02 and PIO mouths 04.
Step S140, the control module 102 receives the standby command by serial ports, and controls the power supply 103 to break
Open.Specifically, in the present embodiment, control module 102 is received after standby command by the PIO mouths 02 in serial ports or PIO mouths 04,
(it is specifically POWER_CTRL pins in PIO mouths 03：System power supply 103 control PIO mouthful) output low and high level come control disconnection
Power supply 103, mutually switches so as to realize between normal work and low-power consumption standby pattern.
In a further embodiment, when above-mentioned pulse signal is low level pulse signal, in above-mentioned step S120
Afterwards, the inside of the normal power supply PIO mouths 01 of its return pulse signal is also set to high resistant by the control module 102, to prevent RF4CE
Module 101 continues input low level pulse to the normal power supply PIO mouths 01 of control module 102 so that the work of control module 102 goes out
Existing confusion.
In addition, control module 102 carries out power down process also when standby to RF4CE modules 101, to realize more low-power consumption.
In a further embodiment, with reference to Fig. 3, the standby controlling method based on RF4CE modules 101 also includes：
Step S210, receives the push button signalling of start or shutdown.Specifically, in the present embodiment, set top box passes through its button
Module 104 receives the various kinds switch key signal that switch key 106 is inputted.
Step S220, digital driving tube 105 is scanned and according to the start or the corresponding control of standby push button signalling output
Signal processed.Specifically, in the present embodiment, the digital model of driving tube 105 can be 1668.When button is by by by under, number drives
The dynamic model of pipe 105 will be standby signal or starting-up signal with determine to be pressed by scanning, it is determined that after pass through digital driving
The PIO mouths 04 (the PIO mouths 04 can be one or more PIO mouthfuls) that pipe 105 itself is communicated with control module 102 notify control
Module 102.
Step S230, the control module 102 is switched on or switched off the power supply 103 according to the control signal.Wherein, control
Signal processed is the standby signal or starting-up signal in step S220.
In addition, with reference to Fig. 2, additionally providing a kind of standby control system based on RF4CE modules 101, including RF4CE modules
101st, control module 102, power supply 103, key-press module 104, digital driving tube 105, switch key 106.
Within the system, when the RF4CE modules 101 receive start guidance command, then output pulse signal；The control
Module 102 passes through an often reception pulse signal of power supply PIO mouths 01, and control power supply 103 to connect；When the RF4CE modules
101 receive standby guidance command, then export standby command；The control module 102 receives the standby command by serial ports, and
The power supply 103 is controlled to disconnect.
Preferably, above-mentioned pulse signal is low level pulse signal；In other embodiments, the pulse signal can be with
It is high level pulse signal.
Further, serial ports is that two very PIO mouthfuls of power supplies are combined.
Further, when pulse signal is low level pulse signal, the control module 102 is receiving the pulse letter
Number, the inside for the normal power supply PIO mouths 01 that control power supply 103 will also receive the pulse signal after connecting is set to high resistant.
Further, the key-press module 104 is used for the push button signalling for receiving start or shutdown；The digital driving tube
105 are used to scan and export corresponding control signal according to the start or standby push button signalling；The control module 102 is also
For being switched on or switched off the power supply 103 according to the control signal.
In addition, a kind of set top box is additionally provided, including the above-mentioned standby control system based on RF4CE modules 101.
Above-mentioned standby controlling method and system based on RF4CE modules 101 make it to lead to by improving RF4CE modules 101
Single PIO mouthfuls of output pulse signal is crossed to control module 102, it is electric in control module 102 to control so that equipment is from holding state
Wake up, not only ensure standby low power consumption characteristic, and PIO mouthfuls and external equipment need not be further added by addition.In addition, by outer
The charactron scanning start/standby keypress function in portion, the communication with control module 102 is to realize idle function, so as to save control
Being used for of molding block 102 starts shooting/standby two PIO mouthfuls of resources by key control.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
