Description
Technical field
The present invention relates to timing wake-up technical field, in particular to a kind of Rouser of terminal, a kind of terminal
Awakening method and a kind of terminal.
Background technology
Remote control generally has two states：Working condition and resting state.As shown in table 1：
Table 1
The static current of lcd of remote control normal work is usually much larger than 30uA, but the operation for that can perform is not limited
System, internal counter is not also limited for timing.In the dormant state, the clock of remote manipulator system is generally all entered and stopped
The state for only working, or low-down working frequency, generally what all can not do, internal counter is also limited, and is used
In timing, can only also count 4 times for 1 second.
Whatsoever the remote control of type has same requirement：Power saving.The national standard requirement remote control of China is standby
When static current of lcd<30uA.And the static current of lcd of remote control normal work is usually much larger than 30uA；Only resting state
Under, static current of lcd<30uA.So, be all requirement remote control when without work, into the pattern of most power saving, generally this
The pattern of kind is dormancy.By mechanical key, change the level state of certain pin, remote control can exit dormancy.
Under the internal timer effect of remote control, remote control can regularly perform various operations, perform such as each second
50-100 operation, operation can be touch key-press detection, temperature detection, Humidity Detection etc..But overall power consumption electric current is more than
30uA.As shown in Figure 1A, it uses internal timing to specific power consumption analysis, and power consumption in this case is 1mA, is quick on the draw, but
It is exceeded power consumption.
Remote control overall power consumption electric current is less than 30uA, but can only wake up that N (N≤4) is secondary each second, performs limited n times
The work such as touch key-press detection.Specific power consumption analysis may be referred to the dormancy of Figure 1B analyses regularly, and power consumption in this case is
10.4uA, meets power consumption requirements, but reaction is slow.

Key touching technique etc., this type of technology has individual feature：Small capacitance is produced to change, or small resistance value changes
Become, or some other parameter changes etc..These variables for changing all are very small, it is necessary to pass through remote control master control actively inspection
Look into, judge whether parameter change, so as to determine whether that button is pressed.For this type of technology, in order to be able to detect in time by
Key is pressed, it is necessary to whether running check button, typically press, detection each second every a 30ms button for remote control of detection
More than 30 times.By the internal timer timing 30ms of remote control, at this time, remote control is in running order.Actively check and press
Bonded state, at this moment remote control be also in working condition.Timing and actively check button alternately, cause remote control to enter
Enter dormancy.
This generates a contradiction：If the remote control that new type presses key technology is used alone, power consumption cannot meet will
Ask.So currently using remote control or mobile phone of the new type by key technology, all generally retain a mechanical key.If made
, for a long time without button operation, remote control or mobile phone are automatically into park mode for user；When use, user presses machine
Tool button, wakes up remote control or mobile phone, and then remote control or mobile phone actively check that specific that button is pressed.By this
Mode reaches the purpose of power saving, but this mode, it is still desirable to mechanical key.
The remote control of standard machinery key wakeup has two kinds of wake-up modes, as shown in table 2：
Table 2
Wherein, the high level of remote control wakes up waveform as shown in Figure 3A, and the low level of remote control wakes up waveform such as Fig. 3 B institutes
Show.
And retain mechanical key, and caused some problems：Capacitance key touching technique, pressure buttons touching technique,
Can be described as entirely without loss, without life-span limitation, and can accomplish to be fully sealed, the distant of this type button technology is used completely
Control device, shell is typically an entirety, very attractive and durable, and mechanical key has service life, and because machinery becomes
The influence of shape, even if there is rubber seal, also can gradually damage with access times, cause the sealing water proofing property of remote control poor.
Therefore, how mechanical key is thoroughly replaced using novel buttons technology, and meet low-power consumption requirement, as current
Problem demanding prompt solution.

Including：
Step 1202, electric discharge.When the operation such as triggering is not detected by Preset Time, wakes up pin and be switched to output mould
Formula, exports low level, serves as discharge circuit, is electric capacity electric discharge.Because capacitance is small, output impedance is mainly pin inner portions resistance
It is anti-, it is general little, by repetition test, it has been determined that the voltage of electric capacity can be charged to 0.1V by 2us discharge times.Therefore originally
The low level discharge time of remote control is 2us.
Step 1204, into resting state, is charged by charging resistor Z to electric capacity.After discharge off, remote control enters most
The park mode of low-power consumption.The discharge path of electric capacity has been cut off simultaneously, and electric capacity passes through charging resistor ZRCharge, voltage can slowly rise
It is high.As shown in figure 13, the discharge time of electric capacity be about 20ms.This parameter is related with capacity to the leakage current characteristic of electric capacity, specifically
The actual capacitance equivalent circuit of Figure 14 is may be referred to, capacitance is bigger, and the charging interval is more long.
Step 1206, wakes up, and performs whether timed task --- -- detection button has the action pressed.
Step 1208, judges whether to continue timing.If detected effective pressure for continuous 3 times increased, it is defined as having
Button is pressed, into keystroke handling program；Otherwise repeat step 1206 to 1206, continues to detect.
