Description
Technical field:
The utility model relates to a kind of power conservation type multikey soft-touch control sensing apparatus, particularly a kind of at condenser type multikey soft-touch control, change its hardware controls framework, to reach a kind of power conservation type condenser type multikey soft-touch control sensing apparatus, can reduce the whole power consumption of touch switch device, especially power saving more when standby.
Background technology:
A kind of known contact witch state checking device, this device has a frequency oscillator that preset frequency can be provided, and can detect that soft-touch control is touched and touch objects is left the checking device of this two states of soft-touch control.
Be widely used on the electronic product as the capacitor type touch switch device, replaced traditional mechanical type keyswitch, though capacitor type touch switch has that its production die sinking is simple and easy, product appearance is attractive in appearance and long-term the use do not have advantages such as machinery is tired down.But its need by detect decision circuitry go to detect always touch the end capacitance variable quantity to judge whether to have or not human body touch, so certain power consumption must be arranged, when key (key) number of touching device more for a long time, the power consumption when standby then can be big more.
Because key (key) number that detects judgement when need increases,, suppose to detect action need current sinking I as the detecting of a key (key) by known power consumption principle
KEY, then detecting action as the detecting of n key (key), can to need current sinking be I
KEYN doubly.
So, key (key) number that detects judgement when need increases, then can cause power consumption to become big or elongated with the time that detects of power consumption with the time, and being in the time of holding state, the switchgear of common product can account for major part, operated state is a bit of once in a while time on the contrary, so the stand-by power consumption of touching device is just very important.Especially all also having its certain stand-by power consumption for multikey (key) capacitor type touch switch device, is big shortcomings stressing the energy-conservation epoch especially.
The utility model content:
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of power conservation type multikey soft-touch control sensing apparatus is provided, detect judgment mode to change touching device when the standby, the electric current that is allowed to condition under the holding state is very little, with the stand-by power consumption of reduction single unit system, and then reach purpose of power saving.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of power conservation type multikey soft-touch control sensing apparatus, and be characterized in: this device comprises: a connectivity port control circuit, integrate several keys touch ends in order to insert; One standby detects the wake-up circuit module, is connected with this connectivity port control circuit, touches total unlatching of end in order to a plurality of keys and is integrated into a key, cooperates the fixed cycle to do the action that monitoring detecting human body has no touch; One scan circuit for detecting module, be connected with this connectivity port control circuit, and detecting the wake-up circuit module with this standby is connected, cooperate standby to detect the wake-up circuit module, if determined, just do to wake up switching to the action of scanning circuit for detecting module and scan each key in regular turn and touch end, determine that in order to detect which key touches end and is effectively touched; And a sequential control circuit, detect the wake-up circuit module with this standby respectively and this scanning circuit for detecting module is connected, detect wake-up circuit module and this scanning circuit for detecting module in order to drive this standby.
The utility model utilizes the hardware control circuit framework that the detecting mode is divided into two kinds of patterns, and one is standby mode, and another detects pattern for scanning.When utilizing standby mode all keys are touched end touch end and do detecting, utilize control circuit that all keys touch ports are opened all keys are touched the end integration as key touch end, detecting the wake-up circuit module via standby detects, when having detected the human body touch, switching to the scanning pattern that detects again detects with scanning circuit for detecting module and determines that those keys touch end and are effectively touched, and leave and touch end in the set time of back and all be not touched again detecting human body, the matching timing control circuit is done control, then switch back standby mode again, use these two kinds of patterns to do detection to reach purpose of power saving.
In view of capacitance type touch key switch senses device, its be in treat machine testing time very greater than be touched the operation time, utilize this key condition, develop under this long-pending body standby mode very power saving and use to go up touching the power conservation type multikey soft-touch control sensing apparatus of possessing certain level with the susceptibility of reaction again.
The detecting recognition of standby mode of the present utility model is several keys to be touched end see through control circuit and be integrated into a key and touch to bring in and do the action that detecting wakes up, needs current sinking I so detect action as the detecting of a key (key)
KEYThough detecting action in the detecting of the known n of a having key (key), can to need current sinking be I
KEYN doubly, but the utility model only need consume under number key (key) scan pattern (1/n) doubly, i.e. detecting detects action and also only needs current sinking I
KEYSo the power consumption of this device under standby mode can reduce.
