Description
Technical field
The present invention is meant a kind of switching device shifter, is meant a kind of proximity sensing (proximity sensing) device and its inducing method of switching device shifter especially.
Background technology
Along with the photoelectricity development of science and technology, the demand of being close to the sensing switching device shifter is constantly increased, common contiguous switching device shifter comprises as contiguous diverter switch and touch-screen etc., is mainly used in the switched system state.The function mode of proximity sense is: when object near in the induction range of described transducer the time, described transducer is touching described object or is not touching under the situation of described object, by responding to the position at described object place, the signal transition that described transducer also will be responded to gained is an electronic signal, system or machine can be made suitable reaction according to described electronic signal, reach the purpose of switched system state.
With the touch-screen system is example, it has a sensor unit to be attached on the display, described sensor unit and controller and device driver software cooperatively interact, and respond to operational motion each time, determine the position of operation and these information are sent to operation system of computer.Traditionally, the common induction technology of adjacent induction device is Electric field, resistance-type, condenser type, sound wave type and optical profile type.
The Electric field technology is called near field imaging (NFI, Near Field Imaging) again.Use the middle two blocks of laminated glass that layer of transparent metal conductive oxide coating is arranged of touch-screen of this technology, on conductive coating, apply an AC signal, thereby form an electrostatic field in screen surface, when finger (be with gloves all can) or other conductor touch transducer, electrostatic field will be interfered, and supporting with it image processing controller can detect described interference signal and the position is also passed to operating system to a corresponding coordinate parameters.Imaging touch-screen near field is very durable, and sensitivity is fine, can use in the rigorous environment very much requiring.
Resistive touch screen is made of the top plate of softness and hard lower plywood, some insulating point distribute between two layers of material, all there is the coating of metal oxides of layer of transparent the inboard of top plate and lower plywood, because the dividing potential drop effect of resistance, the voltage swing of different parts difference to some extent on plank, point touches top plate, can form contact point between top plate and lower plywood, as the switch in the circuit, control circuit becomes location coordinate information with the different voltage transitions that contact point forms.The resistive touch screen power reguirements is simple, industrialization easily, and also suitable application area is wide, but the plastics manufacturing is used on its surface usually, and more soft resistance to wear is relatively poor.
Capacitive touch screen is curved surface or the flat glass that the surface is covered with transparent metal oxide, when the user applies a voltage at screen four jiaos, will absorb different electric currents from four jiaos when not contacting with screen with the finger of gloves or conductor, thereby on screen, form the electric field of an equilibrium, the size of electric current changes the position that control circuit can touch according to the difference decision of electric current along with the touch location difference.Capacitive touch screen is mainly used in the information service equipment of Entertainment kind equipment and public arena, and is little to the influence of image sharpness, touches resolution than higher.Weak point is to need often to recalibrate, and performance is subjected to the influence of long-time wearing and tearing easily.
The ultrasonic waves touch-screen is by the PZT (piezoelectric transducer) emission ultrasonic waves at screen vertical and horizontal edge, on the edge on opposite separately, ultrasound sensors is housed, so just form a crisscross ultrasonic waves grid in screen surface, when finger or other flexible felt pen during, stop and absorbed the sound wave of vertical and horizontal near screen surface.Ultrasound sensors can determine whether that finger or contact pen touch screen according to the variation of sound wave, the different different coordinate positions of transducer representative, and controller can position by supersonic intensity and change in location information butt joint contact.The ultrasonic waves touch-screen is very high to the induction resolution that touches, and durable in use.Another characteristics are less demanding to the evenness on indicator screen surface, so can use preferably on sphere or cylinder monitor.Weak point is that finger and contact pen must can absorb sound wave, is subjected to noise jamming easily, and electric power system is had relatively high expectations, and requires the screen surface cleanliness factor better, and water stain or foul all can influence result of use.
Infrared touch panel is to be basic principle with the light beam interrupter technique, need not cover any material at original display surface, but around display screen, lay a framework, on two opposite side above the framework, light-emitting diode (LED) is installed on one side, another side is installed pyroscan, has so just formed a grid of being made up of infrared ray on the surface of display screen.When any object enters this grid, will stop some light, on pyroscan, will receive the signal of variation, by controller the position coordinates that touches is passed to operating system.The benefit of infrared touch panel is complete printing opacity, does not influence the definition of display, and resolution is very high, but price is higher and lifetime of LED is shorter, is subjected to high light interference in the applied environment easily.
The structure of contiguous diverter switch and the structure and the operation principle of operation principle and above-mentioned touch panel device are roughly the same, but induction installation is installed in the switch position, are used for inductive operation.
Sum up; the operation principle of adjacent induction device mainly can classify as Electric field, resistance-type, condenser type, sound wave type and optical profile type five big classes at present; mainly be that point or zone are done detection; but the contiguous formula inductor of what class no matter; use occasion in reality; regular meeting meets with following difficulty: (1) needs to change design according to the installation environment difference; (2) the sensitivity meeting changes with environmental change; (3) be difficult to avoid for the interference electrically identical with detection, (4) often have the situation of false touch operation to take place.Therefore, though the development of touch and proximity sense is of long duration, still can't popularize in a large number so far.
Therefore, the applicant is in view of the defective that is produced in the prior art, through concentrated test and research, and in line with the spirit of working with perseverance, visualizing the present invention's " adjacent induction device and its inducing method ", can overcome the existing shortcoming of above-mentioned proximity sensing device, below is brief description of the present invention.
