Abstract
An electrical equipment standby controller relates to electric technology, in particular to a standby-state control device used for home electrical appliance. The utility model is composed of a mainframe CPU, a power supply of the mainframe, and is characterized in that this utility model is also composed of a power supply switch of the mainframe, a standby CPU, a real-time clock and a standby power supply, the standby power supply provides electricity to the standby CPU and the real-time clock, and the standby CPU is connected to the mainframe CPU and the power supply switch of the mainframe. The benefit effect of this utility model is that the entire power supply of SCALER IC is shut off by the standby CPU to reduce the power consumption in standby state, that is the prior system remains in a no-electricity condition in the standby state. So at this time, only the standby CPU, the real-time clock works, and the power consumption of this two is very low. The result is that the demand of low power consumption can be easily achieved.
Description
Technical field
The utility model relates to electronic technology, particularly the control device of the holding state of household electrical appliance.
Background technology
Along with present household appliances are more and more higher to requirements of saving energy, a lot of countries and regions wish that all the stand-by power consumption of TV can reduce as far as possible.Though thereby present most SCALER IC oneself provides standby mode to reduce power consumption under the holding state, but because the complicacy of system, under holding state, there is the equipment of a lot of peripheries also to need to be under the duty, as DDR, FLASH etc., therefore to make stand-by power consumption still bigger in this case.
The utility model content
Technical problem to be solved in the utility model is, a kind of electric appliance standby control device is provided, and can greatly reduce the power consumption under the holding state.
The technical scheme that the utility model solve the technical problem employing is, a kind of electric appliance standby control device, comprise host CPU, host power supply, also comprise host power switch, standby CPU, real-time clock and standby power, described standby power is standby CPU and real-time clock power supply, described standby CPU is connected with host CPU, also is connected with host power switch.
Described host CPU is connected with standby CPU by the GPIO pin.Described real-time clock has time register, is used to store the on time of setting.Described standby CPU also is connected with power light with remote-control receiving circuit, localpower button.
The beneficial effects of the utility model are under the state of standby, and standby CPU reduces power consumption under the holding state by the power supply of closing whole SCALER IC components of system as directed, is equivalent to original system and still is in the state that does not power under holding state.Therefore have only standby CPU, real-time clock this moment in work, and the two power consumption is very low.So just can realize the requirement of low-power consumption easily.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Referring to Fig. 1.Electric appliance standby control device of the present utility model, comprise host CPU, host power supply, also comprise host power switch, standby CPU, real-time clock and standby power, described standby power is standby CPU and real-time clock power supply, described standby CPU is connected with host CPU, also is connected with host power switch.
Described host CPU is connected with standby CPU by the GPIO pin.Described real-time clock has time register, comprises the timing function register of the on time of the current time register that is used for the storage system time and setting.Described standby CPU also is connected with power light with remote-control receiving circuit, localpower button.As the component units of block diagram, the particular circuit configurations in the unit is all ripe prior art, so this paper repeats no more.
Specifically, be example with the televisor, the utility model is made up of three parts: television system part, standby CPU part, real-time clock part.Television system partly comprises the perfect television system of a cover such as SCALERIC (host CPU), video decode, ADC, remote control and button.And power supply can be regarded two parts as: i.e. the power supply of standby power and television system (host power supply), the latter is controlled with software by the GPIO pin by standby CPU.
After the user plugged in socket, standby power was started working, the operate as normal power supply that provides standby CPU to need.Standby this moment CPU detects remote-control receiving circuit or localpower key, whether detect has remote signal or localpower boot action, if have, then the GPIO pin by software control is with the power supply opening of components of system as directed, and system just is in the state of normal startup like this.
After television system started, host CPU notified the standby cpu system current standby or the open state of being in by a GPIO being changed to high-low level.If (press the POWER key or timing shutdown is arranged such as the user, turning device to sleep mode, no signal shutdown etc.) just notified it to carry out power-off operation by a GPIO pin that links to each other with standby CPU when this moment, host CPU detected subscriber-related machine operation.At first can detection system is current after standby CPU receives this order whether be in open state, if then turn-off the power supply of original system, the color that power light LED is changed under the standby is simulated holding state simultaneously.
If the user has the operation of timing start-up, can be when the user regulates the time of timing start-up, be written to this time in the timing function register of real-time clock by the I2C bus, the system time that the user is provided with is written in the current time register of real-time clock simultaneously, when carrying out power-off operation, again enable switch being interrupted in the timing of real-time clock opens, like this when in holding state following time, after if the time regularly arrives, and under the enable switch open mode, real-time clock will be carried out the action of start by the GPIO notice standby CPU that links to each other with standby CPU.When standby CPU receive timing start-up in have no progeny, whether detection system is in the state of standby, if then open host power supply, guiding main frame start.Start aft engine CPU reads the current time of preserving in the real-time clock and the information of timing, whether at first detect these information effective, if invalid illustrative system does not carry out normal power-off operation, thereby all time is resetted, what be equivalent to that the user carries out is power operation.If effectively, (this information is preserved before power-off operation then will to be kept at temporal information among the NVRAM, current time during the record shutdown, timing, the length of one's sleep, timing mode etc.) verify, if it is consistent to detect the timing of timing in the real-time clock and preservation, illustrate that this start is to trigger from timing start-up, also will carry out operations such as channel switch after then starting.Simultaneously the current time of current time of real-time clock and preservation is carried out difference relatively calculate other as the length of one's sleep, information such as timing shutdown time, thereby guarantee the integrality that the user is provided with, realize the function of real simulation standby under the complete powering-off state of host CPU.
