Abstract
The present invention provides a kind of double open switch, and a kind of existing keypress function of double open switch has touch function, including a signal input module and a signal detection module again.The signal input module includes a touch input control module, a key-press input control module and an electric capacity.The touch input control module is arranged in parallel with key-press input control module, while the touch input control module after parallel connection is connected together with key-press input control module with the electric capacity.The signal detection module is used to detect the input signal from signal input module, and the output signal for being converted into being adapted to the control module to work according to the input signal.The input signal from signal input module is that touch signal is different and different from push button signalling according to the difference of input, therefore the signal detection module includes a capacitance-sensitive range intervals, and the capacitance-sensitive range intervals should cover the different input signal.
Description
Technical field
The present invention relates to a kind of power control unit, particularly a kind of double open switch.
Background technology
Existing light fixture all uses LED illumination mostly, and a kind of touch has been invented again compared to former key switch, people
Formula inductive switch is touched, contact witch is most widely used in present smart mobile phone screen, and simple contact witch is condenser type
Soft-touch control, capacitor type touch switch are made up of a microprocessor and some peripheral circuits.
In television set, some drivers all be capacitor type touch switch, but the simple structure of capacitance-type switch
Some occasions can not be met.
The content of the invention
The present invention solves the problems, such as that the structure of capacitance-type switch is simple, function is single, there is provided a kind of double open switch.One
The kind existing keypress function of double open switch has touch function, including a signal input module and a signal detection module again.
The signal input module includes a touch input control module, a key-press input control module, and an electric capacity, institute
State touch input control module to be arranged in parallel with key-press input control module, while connected with the electric capacity, the electric capacity it is defeated
Go out and be electrically connected with signal detection module.The signal input module includes a touch input control module, and a button is defeated
Enter control module and an electric capacity.The touch input control module is arranged in parallel with key-press input control module, while simultaneously
The touch input control module after connection is connected together with key-press input control module with the electric capacity.The signal detection mould
Block is used to detect the input signal from signal input module, and is converted into the suitable control module work according to the input signal
The output signal of work.The input signal from signal input module is touch signal and push button signalling according to the difference of input
It is different and different, therefore the signal detection module includes a capacitance-sensitive range intervals, the capacitance-sensitive range intervals
The different input signal should be covered.
A kind of double open switch, can touch sensible, can also be used by key control under the occasion of different requirements, body
Merging for traditional habit and emerging technology is showed.
Brief description of the drawings
Fig. 1 is a kind of circuit theory diagrams of double open switch of the present invention.
Embodiment
With reference to example and the present invention is described in detail referring to the drawings.As shown in figure 1, a kind of double open switch includes one
Individual power module, a signal detection module being electrically connected with the power module, one electrical with the signal detection module
The signal input module of connection, the control module of an output signal for receiving the signal detection module, and one with should
The DC/DC modular converters that control module is electrically connected with.The DC/DC modular converters are according to the output signal of control module, i.e., high
The length of the presence or absence of voltage signal and the duration of the voltage signal to control the switch of the DC/DC modular converters, or
Person is the height of output voltage to control the adjustment of the switch of load and power so as to reach the purpose of light modulation.The power module
For providing electric power for the signal detection module and control module, high voltage is converted to the suitable signal detection module by it
With the low-voltage of control module work.The signal detection module is used to detect the input signal from signal input module, and
The output signal for being converted into being adapted to the control module to work according to the input signal.The input from signal input module
Signal is that touch signal is different and different from push button signalling according to the difference of input, therefore the signal detection module includes one
Individual capacitance-sensitive range intervals, the capacitance-sensitive range intervals should cover the different input signal.The signal input
Module includes a touch input control module, a key-press input control module and an electric capacity.The touch input control
Molding block is arranged in parallel with key-press input control module, while the touch input control module after parallel connection and key-press input control
Molding block is connected with the electric capacity together.
The touch input control module includes a touchpad, has signal when the touchpad is touched by user
A parasitic capacitance can be produced during input, between the touchpad and the earth.Due to when the touchpad is activated, key-press input
Control module is off, therefore, the parasitic capacitance will connect with electric capacity, therefore, the now signal input module
Output signal is the value after the capacitance of the electric capacity is connected with the capacitance of the parasitic capacitance.And when the key-press input controls
When module is activated, the touch input control module will be switched off, and now, the input signal of the defeated people's module of signal will only be
The capacitance of the electric capacity.As long as therefore the capacitance-sensitive range intervals of the signal detection module are set and include the electric capacity
When the value of the capacitance after being connected with parasitic capacitance and the capacitance of the electric capacity, then when the touch input control module is with pressing
When any one in key input control module is activated, the signal detection module will all receive one and come from the signal
The input signal of input module.The control module receives the high voltage output signal of the signal detection module, and its basis should
The presence or absence of high voltage output signal is handled with duration length, and outputs signal to DC/DC modular converters.It is described
Control module is central processing unit.
