Described, energy management is mainly made up of rectification circuit and DC voltage booster circuit, and according to the type of input power, by processing
To electrical appliance required voltage.Concrete structure is as shown in Figure 1.
Although said structure can preferably provide the energy of abundance for electrical appliance, the supply mode of its energy is continuous
's；It is constantly electrical appliance energy supply, it is worked always.The shortcoming of this kind of mode is that electrical appliance continuously works and can waste unnecessary
Power consumption；Especially in electrical appliance is some requirement of real-time applications not high such as Pressure monitoring chip, temperature survey chip,
So intensive mode of operation there is no need.
Then, the present invention devises a kind of interruption, controllable sleep (inoperative) time method for managing power supply.
The content of the invention
It is an object of the invention to overcome continuous energy supply brings in existing chip energy administrative skill power wastage
Problem.A kind of energy management circuit of sleep-awake for electrical appliance and the energy management method of sleep-awake are provided, are made
The overall power consumption of system is greatly reduced.
Technical solution of the invention is as follows：
A kind of energy management circuit of the sleep-awake for electrical appliance, including power supply rectification circuit, DC boosting electricity
Road, low pressure difference linear voltage regulator and electrical appliance, its feature are to set super after described rectification circuit, DC voltage booster circuit
Level electric capacity, timer circuit, on-off circuit and reset circuit, the output end of described super capacitor respectively with described timer
First input of circuit, the first input of on-off circuit are connected with the first input end of reset circuit, described on-off circuit
First output end is connected through described low pressure difference linear voltage regulator with described electrical appliance, the output end of described timer circuit
It is connected with the second input of described on-off circuit, second output end and described reset circuit of described on-off circuit
Second input is connected, and the output end of described electrical appliance is connected with the described input of timer circuit second, and described answers
The position output end of circuit is connected with the second input of described electrical appliance.
The method for carrying out energy management using the energy management circuit of above-mentioned sleep-awake, comprises the following steps：
1) after the energy of power supply first passes through rectification circuit, DC voltage booster circuit treatment, it is stored in described super capacitor
In, when the voltage of storage reaches threshold value, described timer starts timing, now, described on-off circuit, reset circuit and
Electrical appliance etc. is not started working, 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 sent to on-off circuit, is made out
Powered-down road is opened, and the energy of power supply is delivered to described electricity consumption from super capacitor by on-off circuit, low pressure difference linear voltage regulator
Device；Meanwhile, described on-off circuit enables signal to described reset circuit transmission, and described reset circuit sends reset letter
Number；After described electrical appliance is connected to the reset signal of the energy of on-off circuit transmission and reset circuit, start normal work, now
Electrical appliance is in " wake-up " state；
3) after electrical appliance end-of-job, electrical appliance sends end signal to described timer, and described timer is again
Count；When timer is counted again, cut-out enables signal；Return to step 1).
The main working method of the present invention is to allow electrical appliance to work after the short period (wake-up states), the standby long period
(sleep state)；Power consumption of the electrical appliance when dormant power consumption is much smaller than wake-up states.Both states are constantly circulated, from
And the purpose for saving power consumption is reached in whole cycle.
Compared with prior art, the solution have the advantages that：
1) using the mode of operation of sleep-awake, the electrical appliance power consumption in a work period is greatly reduced；General feelings
Under condition, the time needed for electrical appliance (chip) carries out complete signal transacting, transmitting is Millisecond, but after using the present invention,
Allow the chip 1 second, or longer time work is once；In such cases, the actual power loss of chip narrows down to less than 1 ‰.This is not
Power consumption limit between only allowing electrical appliance operationally is weakened, and also causes the design difficulty reduction of power module in system, more
Easily realize.
2) timer can flexibly adjust the relative time of sleep-awake as the core devices of energy management module,
Make the working method of electrical appliance more flexible.Choose suitable timer, it is possible to use electrical equipment 1 second, 10 seconds, 1 minute even
Just work once, can adapt to different application needs in the longer time.
