Description
Technical field
The present invention relates to the technical field of key triggering control, in particular to key triggering energy-saving control method, storage is situated between
Matter, control device and its terminal.
Background technique
It is existing on time for key length to have the protection of time-out judgement using the chip or system that have keypress function more
Mechanism.When long-pressing key is more than that after a certain period of time, then judging as the secondary key is accidentally by and chip can stop the key institute
Corresponding feedback action is to avoid more electric energy are consumed, until key could normal work again after the key relieving being long pressed
Make.It is when sending signal after triggering key, if key quilt by taking infrared remote controller as an example, when power consumption maximum
It accidentally presses, persistently sends signal and without overtime protection, then battery power will exhaust quickly.
Existing chip or system are generally constituted matrix type or T-type key scan with I/O mouthfuls.In no key, chip or
System is in a dormant state to reduce power consumption.
In matrix type keyboard scanning system, long keying protection mechanism is to receive failing edge signal with input port at present
When, it wakes up chip and executes actuation of keys and key time-out is judged by program to realize.When key time-out occurs, program stopped
Chip is entered dormant state by movement corresponding to the key, the very little of system power consumption at this time；So having to unclamp until key
Afterwards, depresses button can just re-execute movement corresponding to the key again.Since key is that input port receives failing edge
Chip is just waken up when signal, the failing edge signal caused by button press again can just reawake chip and execute the key
Movement.The method can decline to a great extent electric energy loss, but continue key still have fraction of electric current by input port it is default on
Pull-up resistor flows to low potential output port, according to the resistance value of pull-up resistor, electric current about few tens of microamps.If multiple same durations of key
It presses, such as infrared remote controller is pushed down by thick and heavy object, can consume a large amount of electric energy.
In T-type keyboard scanning system, since key sweeps the difference of mode, using failing edge signal come by the way of waking up chip
It cannot achieve arousal function.The reason is that T-type keyboard scanning system all I/O mouthfuls at regular intervals will be successively defeated in suspend mode
Whether there is or not keys to detect for low level pulse signal out, so stopping movement entering and stops even if program has determined that key time-out
It sleeps, as long as key also exists, execution actuation of keys will be waken up again.So the long-time key in T-type keyboard scanning system
Protection mechanism is only capable of with program stopped actuation of keys and continues to check whether key is decontroled, and detecting after key is decontroled can just return to
Normal procedure enters suspend mode；Chip is in operating state in the time of lasting key, although it is corresponding dynamic to stop execution key
Make, but still expends sizable electric energy.
So biggish electric energy loss is still had using above two existing long keying protection mechanism, so having one
Fixed room for improvement.

The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
Referring to Figure 1, the embodiment of the present invention provides a kind of key triggering energy-saving control method, the main flow description of method
It is as follows.
Step 100: obtaining the current key triggering information of current key.
Wherein, current key triggering information include current key triggered time information, current key trigger position information with
And with the mutual corresponding current key execution information of current key trigger position information.
Current key triggered time information is the time cycle that key is triggered, and timing is up to pressing since key triggering
Key triggering terminates, if key remains triggering, remains time status.
Current key trigger position information, that is, the location of key being triggered, the acquisition of the position can use more
Kind mode is realized；In one embodiment, can be judged by the low and high level signal exported to current key, if defeated
It is out high level, then explanation is in the state that is triggered, and the position of the output high level signal is the location of triggering key,
Key is in power supply state always at this time；In one embodiment, main control chip is obtained by the way of being scanned to key
Key trigger position, the mode of scanning is by the way of successively detecting, i.e. the mode of cycle detection can further decrease energy
Consumption.
The triggering has been defined after getting corresponding current key trigger position information in current key execution information
Execution order corresponding to position, for example, power-on command, shutdown command etc., therefore current case execution information is as corresponding
Execute order.
Step 200: main control chip is compared according to pre-set preset key information with current key triggering information
To judge whether it is key false triggering state；If current state is key false triggering state, main control chip controls built-in timer
Starting is to enter forced dormancy state after transmission timing signal message.
Wherein, preset key information includes key reference time information, and key reference time information is the benchmark determined,
The as default period in longest triggered time；During judging whether it is key false triggering state, if there is key
Illustrate at this time to be improper triggering beyond the preset time, judges this kind of state for key false triggering state, due to accidentally touching
Generally weight is pushed down key and is caused, therefore only needs the time cycle to key that judgement can be completed to be compared；If working as
Preceding key triggered time information is greater than key reference time information, and main control chip judges state at this time as key false triggering shape
State, main control chip stops sending current key execution information and main control chip enters forced dormancy state；If current key touching
Send out temporal information be less than key reference time information, main control chip judge state at this time as non-key false triggering state, at this time
Main control chip, which works normally, sends corresponding current key execution information.
Built-in timer is preferably the oscillator of power consumption minimum (less than 1 microampere), provides clock signal by the oscillator,
Realize clocking capability.
Step 300: built-in timer wakes up main control chip according to timing signal information with discontinuity, and main control chip judgement is
No to be still within key false triggering state, if current state remains as key false triggering state, main control chip enters forced dormancy
State simultaneously waits be waken up next time；If it is key false triggering state that current state, which is not, main control chip resets and closes built-in meter
When device.
Wherein, timing signal information is the clock signal that oscillator provides, and provides one at interval of the default time
A high level signal or low level signal are to wake up main control chip.
Step 400: current key triggers information after the update of key after acquisition wake-up main control chip；Current key after update
Trigger information include after updating after current key triggered time information, update current key trigger position information and after updating when
Preceding key execution information.
Wherein, there are two kinds of situations for current key triggering information after update, and current key triggers information after respectively updating
Current key triggers information and works as after belonging to information corresponding to the same key and update with current key triggering information
Preceding key triggering information belongs to information corresponding to different key.
Information corresponding to the same key is belonged to, current key triggering information is different time nodes shape after update
The state of corresponding key under state, current key triggering information is corresponded to each other with key triggering information current after update, i.e., identical
The state of key in different time points, therefore current key triggering information is not repeating after corresponding update.
Belong to information corresponding to different key, current key triggering information is to touch with current key before after update
Photos and sending messages do not have any association, and current key triggers information after updating caused by the key as newly triggered.
Current key triggered time information is the time cycle that new key is triggered after update, since the triggering of new key
Timing terminates up to key triggering, if the key remains triggering, remains time status.
Current key trigger position information after update, that is, the acquisition of the location of new key being triggered, the position can
To be realized using various ways；In one embodiment, can be sentenced by the low and high level signal exported to new key
It is disconnected, if output is high level, illustrate in the state that is triggered, and the position of the output high level signal is the new key institute of triggering
The position at place, this stylish key are in power supply state always；In one embodiment, main control chip is used and is swept to new key
The mode retouched obtains new key trigger position, and the mode of scanning is by the way of successively detecting, i.e. the mode of cycle detection can
Further decrease energy consumption.
This has been defined after getting corresponding new key trigger position information in current key execution information after update
Execution order corresponding to trigger position, for example, power-on command, shutdown command etc., therefore current case execution information is pair
The execution order answered.
Step 411: main control chip to key trigger position information current after update and current key trigger position information it
Between be compared, if after updating current key trigger position information it is identical with current key trigger position information and after updating currently
Key triggered time information is greater than key reference time information, determines that current state remains as key false triggering state.
Step 412: if current state remains as key false triggering state, main control chip enters forced dormancy state and waits
Next time is waken up；If it is key false triggering state that current state, which is not, main control chip resets and closes built-in timer.
Wherein, the method for determining key false triggering state is identical as current key triggering information, according to preset key information
Included key reference time information, key reference time information is the benchmark determined, when as default longest triggers
Between the period；During judging whether it is key false triggering state, illustrate this beyond the preset time if there is key
When be improper triggering, judge this kind of state for key false triggering state, since accidentally touching generally weight is pushed down key and led
It causes, therefore only needs the time cycle to key that judgement can be completed to be compared；Current key triggered time letter after update
Breath is greater than key reference time information, that is, is determined as key false triggering state.
Step 421: if current key trigger position information is different from current key trigger position information after updating, determining to work as
Preceding state is not key false triggering state.
Step 422: whether current key triggering information is in key and accidentally touches after the accessed update of main control chip judgement
Hair-like state；If current state is key false triggering state, main control chip controls built-in timer initiation with transmission timing signal letter
Enter forced dormancy state after breath.
Step 423: built-in timer wakes up main control chip according to timing signal information with discontinuity, and main control chip judgement is
No to be still within key false triggering state, if current state remains as key false triggering state, main control chip enters forced dormancy
State simultaneously waits be waken up next time；If it is key false triggering state that current state, which is not, main control chip resets and closes built-in meter
When device.
Wherein, due to the key in decision process, occurring changing triggering, then preliminary judgement be not key false triggering
State, i.e. main control chip are directly restored to normal operating conditions, carry out judging whether it is key false triggering to the key newly triggered
State.
The method for determining key false triggering state is identical as current key triggering information, according to included by preset key information
Key reference time information, key reference time information are the benchmark determined, as default period in longest triggered time；
During judging whether it is key false triggering state, if there is key beyond the preset time i.e. illustrate at this time for it is non-just
Normal triggering judges that this kind of state for key false triggering state, since accidentally touching generally weight is pushed down key and caused, therefore only needs
Time cycle to key judgement can be completed to be compared；If current key triggered time information is greater than key after updating
Reference time information, main control chip judge state at this time as key false triggering state, main control chip stop send update after when
Preceding key execution information and main control chip enters forced dormancy state；It is pressed if current key triggered time information is less than after updating
Key reference time information, main control chip judge state at this time as non-key false triggering state, and main control chip works normally at this time
Send current key execution information after updating accordingly.
