Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1: please referring to Fig. 1-7, the intelligent power saving system in a kind of wearable device, including camera shooting head end and wrist-watch
End images and is wirelessly connected between head end and wrist-watch end.
Wherein, head end is imaged as shown in Figure 1, including sensor module (including imaging sensor, sound transducer, temperature
Sensor and photosensitive sensor), CPU, camera, microphone, loudspeaker, key, infrared lamp and wireless communication module, the CPU
It is separately connected sensor module, camera, microphone, loudspeaker, key, infrared lamp and wireless communication module.Head end is imaged to be responsible for
Data sampling, analysis, and judge, itself Three models (normal mode, shallow sleep pattern, deep sleep mode) it
Between while switch, also inform wrist-watch end, wrist-watch end switching working mode under its instruction.
Wrist-watch end as shown in Fig. 2, include CPU, key, microphone, loudspeaker and wireless communication module, CPU be separately connected by
Key, microphone, loudspeaker and wireless communication module, wrist-watch end are responsible for starting, close electricity-saving function as master control, and by wireless
Camera shooting head end is informed in communication.
The workflow of system opens a cycle timer as shown in figure 3, in normal workflow, when timing
Between be T1.When timing reaches, execute corresponding detecting event: timer COUNT1 increases timing, and turn on sensor is extracted
Sampled data analyzes these data, and judges whether it is " wake events ".If it is " wake-up ", timer is reset；Otherwise, than
" preset value PRE_TIMER1 " whether is exceeded compared with timer, if exceeding " preset value ", has entered battery saving mode, if small
In " preset value ", timing detecting event next time is waited.Timing T1: specific value requires to be arranged according to real system, and one
As be 10-20 seconds.Timer COUNT1: for measuring the timer for whether entering battery saving mode.Preset value PRE_TIMER1: tool
Body numerical value requires to be arranged according to real system, is the integral multiple of T1, generally 1-3 times of T1.Wake events: detection device uses ring
The anomalous event in border, such as: article falls, opens the door, baby crying, phonetic order.In case of this kind of event, system is decided that
It wakes up or continues to work in normal mode, and issue corresponding " event " (e.g., text, voice prompting), to reach prompting mesh
's.
Embodiment 2, on the basis of embodiment 1, the electricity saving method of the design are specific as follows: where the shallow main stream of sleep
For journey as shown in fig. 6, into shallow sleep pattern, system uses necessary method, reduces power consumption.Shallow sleep timer COUNT2 increases
Timing, and sensing data is extracted, analytical sampling data judge whether it is wake events, if it is wake events, just cancel drop
The behavior of low-power consumption makes system restore normal.If not wake events, also need to judge whether shallow sleep timer is greater than default
Value PRE_TIMER2, if it is greater, then into deep sleep mode, otherwise, systems stay sampling analysis.
In shallow sleep pattern, to reduce power consumption, the measure mainly taken:
A, reduce volume of transmitted data: reducing sensor image sampling frame per second (e.g., 25FPS is reduced to 1FPS), mitigate coding
Device and data transmit IC workload；
B, backlight is closed in LCM suspend mode.
At this point, audio data samples, coding remain unchanged, data communication is also remained unchanged.The purpose done so: part drops
Low-power consumption, meanwhile, it, can non-delay recovery sound, video data transmission when external " wake-up " occurs.Shallow sleep timer
COUNT2: for measuring the timer for whether entering deep sleep.Preset value PRE_TIMER2: specific value is according to real system
It is required that setting, specific value are general are as follows: 5-10 seconds.Shallow sleep pattern enters the judgment basis of deep sleep mode: entering and shallowly sleeps
The total time of sleep mode, system entered deep sleep mode beyond preset value (such as: 5 seconds).
Deep sleep mode main flow as shown in fig. 7,
Into deep sleep mode, system uses necessary method, further decreases power consumption, and it is fixed to open a cycle
When device, timing T2.When timing reaches, corresponding detecting event: synchronous communication is executed, turn on sensor is extracted
Sampled data, analytical sampling data, judges whether it is wake events, if it is wake-up, cancels the behavior for reducing power consumption, makes system
Restore normal.If not wake events, closure sensor waits detecting event next time to arrive.
In deep sleep mode, to reduce power consumption, the measure mainly taken:
1) data source (sound, video data etc.) is closed；
2) wireless communication is closed；
3) master chip suspend mode.
Concrete measure citing:
A closes sensor and its encoder；
B closes mic and its encoder；
C suspend mode wirelessly communicates IC；
D closes video decoding and its display；
E closes audio decoder and its broadcasting.
The timing T2 of timer is a key parameter, is determined by following factor:
1) power saving effect, the time is longer, and dormancy time is longer, more power saving；
2) keeping in communication, it is normal to connect, this is related with specific wireless communication realization.When frequency hopping usually with wireless communication
Between it is related；
3) extraneous " wake events " are made accordingly in time, timing is shorter, and detecting is more timely, accordingly faster.
Synchronous communication:
The wireless communication realized by frequency-hopping mode, Hopping time are usually fixed.In each frequency hopping point, restore communication in time,
Just it is able to maintain the normal of communication connection.The wireless communication of non-hopping mode then needs first to judge whether present communications channel can be used, such as
Fruit is available, with regard to normal communication, otherwise, it is necessary to search for available channel.
