In the power-offstate, when keyswitch S1 closes, the first end ground connection of described electronic switch Q2, described electronic switch Q2 conducting, the enable pin EN of described dc-dc 10 is high level, described dc-dc 10 works, and export the voltage after adjustment to controller 20, controller 20 starts and starts working.After described controller 20 starts, start to detect the closed time length of keyswitch S1, when keyswitch S1 closure time long enough, such as be greater than 3 seconds, then make control end PWR_CTRL_1 export high level always, electronic switch Q1 and Q2 conducting, enable pin EN is high level always, even if at this moment keyswitch S1 rebounds and is disconnected, be also control enable pin EN by controller 20 dc-dc 10 is normally worked, provide operating voltage to controller 20.Now, controller 20 controls electronic switch Q3 conducting by power control terminal PWR_CTRL_2, and power supply 2 powers to camera 3, cradle head control plate 4 and electron speed regulator 5.
If the time that keyswitch S1 is closed is shorter, be such as less than 3 seconds, the control end PWR_CTRL_1 of controller 20 does not export high level, when keyswitch S1 rebounds and disconnects, and system cut-off.
Under open state, detected the closed number of times of keyswitch S1 by sense terminal KEY_DET, and according to the closed number of times of keyswitch S1, send instruction to cradle head control plate 4 by the Schema control end MODE_CTRL of controller 20, control the mode of operation of whole system, as dormancy etc.When the time long enough that keyswitch S1 single is closed, be such as greater than 3 seconds, then the control end PWR_CTRL_1 output low level of controller 20, electronic switch Q1 and Q2 not conducting, enable pin EN is low level, and system cut-off, quits work.
Under open state, when system long time no operations, controller 20 can detect keyswitch S1 by sense terminal KEY_DET and not close in the given time, by described control end PWR_CTRL_1 output low level, make enable pin EN be low level, the power-off of electricity system, quits work.
It should be noted that, signal generation unit 30 can be also other circuit, is again no longer described in detail.In addition, when keyswitch S1 can autonomous Trig control signal, then signal generation unit also can omit, and such as, when keyswitch S1 is the virtual switch on touch-screen, or is the mechanical switch etc. with sensor.
In the above-described embodiment, controller 20 is by the different operating state of detecting keyswitch S1, control the duty of power supply 2 or electronic equipment respectively, such as, when described keyswitch S1 is in the first predetermined registration operation state, described controller 20 controls the duty of described power supply 2, and when described keyswitch S1 is in the second predetermined registration operation state, described controller 20 controls the mode of operation of described electronic equipment.
It should be noted that, when power supply 2 can supply required voltage directly to controller 20, then electric pressure converter 10 also can omit.
The mode of operation of keyswitch S1 can be the length of the running time of keyswitch S1, number of operations, operator scheme etc.The length of running time can set according to different demand, and such as, whether the time that keyswitch S1 is closed judged more than 3 seconds.The number of operations of keyswitch S1 also can set according to different demand, and such as, the number of times that keyswitch S1 closes continuously more than three times, then control electronic equipment and enter the second mode of operation, otherwise electronic equipment remains on the first mode of operation.The operator scheme of keyswitch S1 also can set according to different demand, such as, keyswitch S1 can press the combination switch that also can rotate, then the operator scheme of keyswitch S1 is for press die pressing type and rotation mode, or, keyswitch S1 is the virtual switch on touch display screen, then the operator scheme of keyswitch S1 can be original place point blow mode and sliding-modes.
Please refer to Fig. 2, based on above-mentioned control circuit 1, embodiments of the present invention also provide a kind of control method, and described control method comprises: the mode of operation obtaining keyswitch S1; And according to the mode of operation of described keyswitch S1, optionally control the duty of described power supply 2 or the mode of operation of described electronic equipment by controller 20.

Step 102, described controller 20, according to the voltage of its sense terminal KEY_DET, judges that whether time that keyswitch single is closed is more than a Preset Time, such as 3 seconds; If more than 3 seconds, then arrive step 103; If be no more than 3 seconds, then system held off-mode.
Step 103, system boot.
Step 104, under open state, judges whether keyswitch S1 has again closed, if so, then arrives step 105, if not, then arrive step 107.
Step 105, judges that keyswitch single is closed and if so, then arrives step 106 whether more than 3 seconds, if not, then arrive step 108.
Step 106, system closedown.
Step 107, judges that whether keyswitch disconnects more than a Preset Time, such as 60 seconds; If so, namely system long time no operations, then arrive step 106; If not, system held open state.
Step 108, the number of times that detecting keyswitch single closure time is no more than 3 seconds.
Step 109, if the number of times that keyswitch single closure time is no more than 3 seconds is 1, is then set to pattern one system.
Step 110, if the number of times that keyswitch single closure time is no more than 3 seconds is 2, is then set to pattern two system.
As required, can system operating mode be increased, such as, if detecting the number of times that keyswitch single closure time is no more than 3 seconds is 3, then system is set to pattern three.These system models can be dormancy, time-lapse shooting, auto-focusing etc.
Common dc-dc has enable pin, and when enable pin is high level, dc-dc can normally work; When enable pin is low level, dc-dc quits work, even if input is normal, does not also have output.
