Abstract
The invention relates to a capacitive touch inductive button control panel with a vibration feedback function, comprising a touch inductive button sensor, a touch inductive button detection chip, a micro motor drive circuit part, an RCU (Room Control Unit) interface circuit part, a power supply switching circuit and a micro motor, wherein the touch inductive button sensor is used for detecting the finger touch of a user and passing the touch action of a finger to the touch inductive button detection chip, the touch inductive button detection chip is used for transforming the touch signal into an electrical signal and then sending the electrical signal to an RCU via the RCU interface circuit after the finger of the user is confirmed to touch above the touch inductive sensor, and the micro motor inside the control panel is driven to act by the touch inductive detection chip according to the touch signal to respond to the button touch action of an operator in a vibration feedback mode.
Description
Technical field
The touch sensible that the present invention relates to the charge transfer capacitance formula need to be specially adapted to anti-electricity, waterproof, protection against the tide, anti-greasy dirt, a kind of capacitance touch induced key control panel with vibrations feedback function of finger explosion-proof, that need the high sensitivity inductive effects by key technology.
Background technology
In the tradition touch key-press product, what most of product adopted is resistive touch screen, the type touch-screen serviceable life is long, sensitivity is not high, the false action-proof ability is relatively poor (anything is run into all and can move), and some use the signal to noise ratio (S/N ratio) of touch-screen of capacitive technologies not high on the market, stability is not high, higher to the humidity requirement of working environment.Compare with traditional button in addition, it is the sensation that does not have button that the touch sensible button uses, and it is not tangible that the user can feel, do not have feel.
Summary of the invention
The purpose of this invention is to provide a kind of capacitance touch induced key control panel with vibrations feedback function, when touch sensible button detection chip detects user's hand when touch sensible button control panel moves, the micro motor work that meeting drive controlling panel inside carries feeds back to the user in the mode that shakes and represents that the touch sensible button is pressed.
Realize that technical scheme of the present invention is: this capacitance touch induced key control panel with vibrations feedback function, it is characterized in that comprising the touch sensible key sensor, touch sensible button detection chip, the micro motor driving circuit partly, the RCU interface circuit partly, power-switching circuit, micro motor, finger touch touch sensible key sensor wherein, the touch sensible key sensor will touch the finger movement signal and pass to touch sensible button detection chip, touch sensible button detection chip is converted to the micro motor action that electric signal sends RCU to and carries by micro motor driving circuit drive controlling panel inside by the RCU interface circuit with this touch signal, micro motor is responded in vibrations feedback mode and is touched finger, and power-switching circuit is respectively the touch sensible key sensor, touch sensible button detection chip, the micro motor driving circuit partly, the RCU interface circuit partly, the micro motor power supply.
This technical scheme also comprises:
Described touch sensible key sensor connects micro motor through touch sensible button detection chip, single-chip microcomputer, micro motor driving circuit.
Described micro motor driving circuit partly comprises chip U1, this chip U1 pin 13 connects triode Q1 base stage through resistance R 7, triode Q1 collector is through capacitor C 8, diode D7 cross-over connection micro motor two ends, chip U1 pin 7,8 cross-over connection crystal oscillator Y1, chip U1 pin 23-28 connecting interface circuit J2, chip U1 pin 29 meets reset switch SW1 through capacitor C 19.
The beneficial effect that the present invention has: though touch inductive control board and common button keys control panel Comparatively speaking convenient a lot of but lacked tangible sense and operation senses that finger tip is pushed, the affirmation means of input state effect are to judge by the feedback sound of visuognosis and input fully, and whether with decision operation correct and bring user brand-new control impression and I take charge of the capacitance touch induced key control panel of the button band vibrations feedback function of design if can produce vibrating effect by the motor of panel inside.
