Described, energy management is mainly made of rectification circuit and DC voltage booster circuit, and according to the type of input power, by handling
To electrical appliance required voltage.Specific structure is as shown in Figure 1.
Although above structure can provide sufficient energy preferably for electrical appliance, the supply mode of its energy is continuous
's；It is constantly energized for electrical appliance, it is made to work always.It is unnecessary that the shortcomings that such mode, is that electrical appliance continuous work can waste
Power consumption；It is especially that Pressure monitoring chip, temperature measure in the not high application of some requirement of real-time such as chip in electrical appliance,
Operating mode intensive in this way is not necessarily to.
Then, the present invention devises the method for managing power supply of intermittent, controllable sleep (inoperative) time a kind of.
Summary of the invention
It is an object of the invention to overcome in existing chip energy administrative skill continuously to energize bring power wastage
Problem.A kind of energy management circuit of the sleep-awake for electrical appliance and the energy management method of sleep-awake are provided, made
The power consumption of system entirety is greatly reduced.
Technical solution of the invention is as follows:
A kind of energy management circuit of the sleep-awake for electrical appliance, rectification circuit, DC boosting electricity including power supply
Road, low pressure difference linear voltage regulator and electrical appliance, it is characterized in that being arranged after the rectification circuit, DC voltage booster circuit super
Grade capacitor, timer circuit, switching circuit and reset circuit, the output end of the super capacitor respectively with the timer
First input of circuit, the first input of switching circuit are connected with the first input end of reset circuit, the switching circuit

It is connected with the second input terminal of the switching circuit, the second output terminal of the switching circuit and the reset circuit
Second input terminal is connected, and the output end of the electrical appliance is connected with second input terminal of timer circuit, and described answers
The output end of position circuit is connected with the second input terminal of the electrical appliance.
The method for carrying out energy management using the energy management circuit of above-mentioned sleep-awake, including the following steps:
1) after the energy of power supply first passes through rectification circuit, DC voltage booster circuit processing, it is stored in the super capacitor
In, when the voltage of storage reaches threshold value, the timer starts timing, at this point, the switching circuit, reset circuit and
Electrical appliance etc. is not started to work, and electrical appliance is in a dormant state；
2) when the timer circuit timing number described in reaches the threshold value of setting, enable signal is issued to switching circuit, is made out
Powered-down road is opened, and the energy of power supply is transmitted to the electricity consumption by switching circuit, low pressure difference linear voltage regulator from super capacitor
Device；Meanwhile the switching circuit transmits enable signal to the reset circuit, the reset circuit, which issues, resets letter
Number；After the electrical appliance is connected to the energy of switching circuit transmitting and the reset signal of reset circuit, start to work normally, at this time
Electrical appliance is in " wake-up " state；
3) after electrical appliance work, electrical appliance issues end signal to the timer, and the timer is again
It counts；When timer counts again, enable signal is cut off；Return step 1).
The main working method of the present invention is the standby long period after allowing electrical appliance work short period (wake-up states)
(sleep state)；Power consumption of the electrical appliance when dormant power consumption is much smaller than wake-up states.Both states constantly recycle, from
And achieve the purpose that save power consumption in whole cycle.
Compared with prior art, the solution have the advantages that:
1) operating mode for using sleep-awake, is greatly reduced the electrical appliance power consumption in a duty cycle；General feelings
Under condition, the time needed for electrical appliance (chip) carries out complete signal processing, transmitting is Millisecond, but after using the present invention,
Allow the chip 1 second, or the longer time works once；In such cases, the actual power loss of chip narrows down to 1 ‰ or less.This is not
Only allow electrical appliance at work between power consumption limit weakened, but also in system power module design difficulty reduce, more
Easily realize.
2) core devices of the timer as energy management module, can with the relative time of flexibly adjustment sleep-awake,
Enable the working method of electrical appliance more flexible.Choose suitable timer, can be used electric appliance 1 second, 10 seconds, 1 minute even
Just work is primary in the longer time, can adapt to different application needs.
