Abstract
The invention provides a method for lowering the energy consumption of electronic equipment. The method comprises the following steps: when the electronic equipment works in a normal mode, storing data and configuration information in a random access memory and a cache storage area; entering a sleep mode after preset time; turning off the power supply of a working circuit by a power supply control module after the power supply control module receives a sleep state instruction; transmitting a power supply signal to the power supply control module for supplying power to the working circuit after an equipment detection module detects the change of the equipment working state; recovering all data in the random access memory after the working circuit is electrified, and returning to the normal working mode to prepare to work. By adopting the method for lowering the energy consumption of the electronic equipment, the equipment can rapidly enter a power-saving sleep mode after exiting from the working mode, data and system configuration information are stored and recovered through the random access memory, and the instantaneity of mode switching is ensured through the detection module, so that good user experience is provided.
Description
Technical field
The present invention relates to electron controls technology field, particularly a kind of method that reduces electronic device energy consumption.
Background technology
The power consumption that reduces electronic equipment always is an important problem.If electronic equipment is in a very long time in standy operation mode, its stand-by power consumption is that highly significant is important.Take a powder consumption of electronic equipment only as the standby mode of 0.5W is example, if every day, stand-by time was 5 hours, its annual power consumption consuming will surpass 900W, 100,000 such equipment within 1 year, slattern electric energy be exactly 90,000 kilowatt hours.And general electronic equipment is all provided with sleep pattern, its needed power consumption will be lacked much compared with standby mode, therefore, shortens the standy operation mode time of equipment, and directly enter sleep pattern, will save more electric power by help equipment.
Summary of the invention
The object of the present invention is to provide a kind of method that reduces electronic device energy consumption, by making equipment one period of schedule time after the state of deactivating laggardly enter sleep pattern and reduce a large amount of energy and consume.
To achieve the object of the present invention, a kind of method that reduces electronic device energy consumption of the present invention comprises the steps:
S1, electronic equipment are worked under normal mode, and by all or partial data storage with random access memory (RAM) and device configuration information is stored in buffer memory district;
S2, electronic equipment is set in one schedule time of the pattern of deactivating, laggardly enters sleep pattern;
S3, energy supply control module are closed operating circuit power supply after receiving sleep state order;
S4, equipment sensing module detect equipment working state and send after changing power supply signal to energy supply control module;
S5, energy supply control module start power supply to equipment operating circuit; And
S6, operating circuit obtain all data of storing in electric rear recovery random access memory and are stored in the device configuration information in buffer memory district, get back to normal mode of operation preliminary work.
Preferably, described, also comprise that the equipment of the setting pattern of deactivating enters standby mode after one schedule time equipment enters sleep pattern step from mode of operation is set, and then laggardly enter sleep pattern through a schedule time.
Preferred again, it can be by touching or the mode of pressing keys or come detection equipment duty to change by gravity sensor or by infrared detector that described equipment sensing module detects in the step of equipment working state change.
The method of reduction electronic device energy consumption of the present invention can make equipment after the pattern of deactivating, enter fast the more sleep pattern of economize on electricity, by random access memory, store and recover data and system configuration, and the instantaneity while guaranteeing that by detecting module pattern is switched, provide good user to experience.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that a kind of schematic diagram that reduces the method for electronic device energy consumption of the present invention.
Embodiment
In conjunction with the schematic diagram of the method for the reduction electronic device energy consumption of the one embodiment of the invention shown in Fig. 1, the method for described reduction electronic device energy consumption comprises the steps:
S1, electronic equipment are worked under normal mode, and by all or partial data storage with random access memory (RAM) and device configuration information is stored in buffer memory district;
S2, electronic equipment is set in one schedule time of the pattern of deactivating, laggardly enters sleep pattern;
S3, energy supply control module are closed operating circuit power supply after receiving sleep state order;
S4, equipment sensing module detect equipment working state and send after changing power supply signal to energy supply control module;
S5, energy supply control module start power supply to equipment operating circuit; And
S6, operating circuit obtain all data of storing in electric rear recovery random access memory and are stored in the device configuration information in buffer memory district, get back to normal mode of operation preliminary work.
Current electronic equipment arrange standby mode be for user more quick when equipment being waken up to mode of operation, data and configuration information in the time of can keeping entering standby mode after equipment end-of-job due to standby mode, therefore, while waking up to mode of operation from standby mode, equipment, without re-starting system setting, can be proceeded duty very easily.In one embodiment of the invention, in order to provide the user of user when carrying out mode of operation switching to experience, guarantee that mode of operation is switched quick, adopt random access memory (RAM) and buffer memory district to carry out Save and restore data and system configuration information, in addition, adopt detecting module immediately to learn that equipment state carries out the switching of mode of operation.One preferred embodiment in, described equipment sensing module is by touching or the mode of pressing keys or come detection equipment duty to change by gravity sensor or by infrared detector.During such as use gravity sensor, as long as when user picks up equipment again, detecting module will be learnt this Status Change at once, notice energy supply control module is powered to operating circuit, recovery mode of operation.
In another embodiment, described, also comprise that the equipment of the setting pattern of deactivating enters standby mode after one schedule time equipment enters sleep pattern step from mode of operation is set, and then laggardly enter sleep pattern through a schedule time.So also can improve reasonable user and experience, also can reach the object that reduces energy consumption simultaneously.
Because the energy consumption of equipment when the sleep pattern is only that approximately one of percentage of standby mode is to 1/10th left and right, method of the present invention can make equipment after the pattern of deactivating, enter fast sleep pattern, avoid long standby power consumption state, reduced the energy consumption of equipment.
Electronic equipment of the present invention in when work, can store all or part of data and system configuration into random access memory (RAM) and buffer memory memory block (Flash) in after, just enter into sleep pattern, after equipment wakes up, these data and configuration can return to the state before sleep.Therefore, all configurations, parameter and state can keep.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
