Abstract
The invention provides a penetration type control device of a touch screen, which comprises a plurality of touch sensors and a signal controller. The touch sensors are adhered on the back of a touch medium, and are respectively connected with a plurality of input units on the signal controller, wherein the quantity of the touch sensors corresponds to that of the input units, the input units are respectively connected with a single chip microcomputer on the signal controller via filters, the single chip microcomputer is connected with a PC (personal computer) via a USB (universal serial bus) interface, a plurality of input signals include switch signals or 3-5V electric pulse signals, the signal controller converts the input signals into codes of a keyboard of the PC, the codes are inputted into the PC via the USB interface, namely if a user touches a certain icon on the touch screen, a corresponding code of the keyboard of the PC is pressed down, and the touch screen is made of non-metal glass or ceramics or a wood plate or acryl.
Description
Technical field
The present invention relates to a kind of touch sensible technology, refer to especially a kind ofly can become keyboard signal that electric signal is directly changed into PC to control each PC touch sensible on any nonmetallic substance surface in the certain thickness scope.
Background technology
Traditional touch screen; Be sensor installation (resistance/infrared/table ripple) on the display of regulation, through the touch location of staff on display screen changed into relative X-Y coordinate, thereby change into mouse signal; Complex structure, cost strengthen with screen size and raise.
Summary of the invention
The present invention provides a kind of penetration touch-screen control device; Comprise touch sensor and signal controller, be attached at the touching medium back side with a plurality of touch sensors, each sensor respectively with signal controller on have a respective amount a plurality of input blocks be connected; A plurality of input blocks are connected with single-chip microcomputer on the signal controller through wave filter respectively; Single-chip microcomputer is connected with PC through USB interface, and said a plurality of input signals are electric impulse signals of switching signal or 3-5V; Signal controller converts a plurality of input signals to the PC keypad code through USB interface input PC, and the said screen of touching is nonmetal glass or pottery or plank or acrylic.
Said touch sensor is in a printed board, to be provided with three pin hole slots; A waver and a chip, waver is connected with a plurality of adjustment electric capacity respectively, and adjustment electric capacity is connected with chip; The back side of printed board is metal aluminum foil; The metal aluminum foil face of printed board is attached at the back side of touch-screen, said adjustment electric capacity, the size of the electric capacity of being responded to when being adjustment human body touch touch-screen.
Said signal controller is established a single-chip microcomputer and is connected with a plurality of wave filters; A plurality of wave filters are connected with a plurality of input signals respectively, and single-chip microcomputer also is connected with USB interface with a read-write controller, and USB interface is connected with PC; Said single-chip microcomputer is with the switching signal or the electric impulse signal of a plurality of inputs; Converting the keypad code input PC of corresponding PC to, promptly on touch-screen, touch certain and indicate, is the keypad code of pressing PC.
The invention has the advantages that the touch signal of finger is not the X-Y coordinate that converts mouse to, but directly change into the novel touch signal controlling technology that the customizing keyboard value supplies the user directly to call, simple in structure, use general enclosing extensively.
The present invention has broken through the limitation that conventional touch screen can only partly touch at display, and the point that touches is distributed in the outer any position of display.And any nonmetallic substance in the certain thickness scope being changed into touching medium. sensor is hidden in and touches by the back side; Broken through the limitation that conventional touch screen can only change into touch signal mouse signal, touch signal has been changed into keyboard signal input to computer.
Break through conventional touch screen and can only use the limitation of finger touch; To touch meaning and extensively change, and can any extraneous switching value signal and electric screen signal be changed into keyboard input signal, that is to say; Can push what point; Click, the pressure signal of people's pin, the motor message of the person are directly as the extraneous trigger pip that triggers the keyboard input.Enlarged the scope that people carry out man-machine interaction.
