Embodiment
Below in conjunction with accompanying drawing and embodiment scheme according to the invention is described in detail.
Provided by the invention pair of contactor control device, as shown in Figure 1, comprising: contact panel 1, infrared detecting device, reflecting strips 4, electromagnetic induction wiring board 5 and control module 6.
Infrared detecting device comprises infrared spotlight 2 and image received device 3, is arranged on contact panel 1 adjacent two drift angle places.Infrared spotlight 2, be installed in said image received device 3 near, and the light-sensitive surface of as close as possible image received device can better be received by image received device to guarantee the infrared light that infrared spotlight sends; Said image received device can be imageing sensor.
Electromagnetic induction wiring board 5 is arranged on contact panel 1 below.Electromagnetic induction wiring board 5 comprises mutual vertically disposed transmission coil groups and receiving coil group.Time writer inside has the sensor circuit of being made up of electric capacity and telefault, when time writer during near the electromagnetic induction wiring board, receives excitation of sending coil and the electromagnetic induction signal that produces fixed frequency; Receiving coil on the electromagnetic induction wiring board receives the electromagnetic induction signal of time writer generation and sends to control module; Control module is calculated according to said electromagnetic induction signal, can obtain the time writer touch information, thereby realizes the location to time writer.
Control module 6; Connect infrared detecting device and electromagnetic induction wiring board respectively, be used to receive infrared touching signals and/or electromagnetic induction signal, and according to the priority that is provided with in advance; Touching signals to priority is high is handled, and obtains the touch information of touch object.
Particularly, when the user used time writer that contact panel 1 is operated, control module 6 can get access to electromagnetic induction signal and infrared touching signals simultaneously; Control module 6 is handled the touching signals that priority is high according to the priority that is provided with in advance, obtains the high touch information of priority and sends to computing machine, and the touching signals that priority is low is not then handled.
When the user uses the touch object of other types, when carrying out touch control operation,,, and obtain the touch information of touch object according to this infrared touching signals so control module can only receive infrared touching signals because finger can not produce electromagnetic induction signal like finger.
Seeing that the characteristics of the hi-Fix of electromagnetism touch technology, here, control module priority processing electromagnetic induction signal.
For saving space in the contactor control device, control module 6 can be arranged on the electromagnetic induction wiring board 5.
As shown in Figure 2, said control module 6 comprises: signal receiving module 21, priority are provided with module 22 and touch-control locating module 23;
Signal receiving module: the touching signals that is used to receive touch object such as time writer, finger etc.;
Priority is provided with module, is used to be provided with the priority that the touching signals that is received is handled;
The touch-control locating module is used for the priority according to the touching signals that is received, and the touching signals that priority is high is handled, and obtains the touch information of touch object, touch object is positioned, not the low touching signals of processing priority.
Two contactor control devices that the embodiment of the invention provided; The pinpoint accuracy that not only has the electromagnetic induction touch-screen; The advantage of support pressure induction and handwriting input; But also have the advantage to touch object less-restrictive of infrared touch panel, and be applicable to the large scale screen, widened the scope of application of touch-screen.
Based on said apparatus, the present invention also provides the localization method of a kind of pair of touch-control, and is as shown in Figure 3, may further comprise the steps:
Step 301: the priority that touching signals is handled is set;
In this step, touching signals can comprise electromagnetic induction signal and infrared touching signals; Owing to utilize the bearing accuracy of electromagnetic induction touching technique higher, so the priority that electromagnetic induction signal is set in the present embodiment is higher than infrared touching signals.
Step 302: receive one or more touching signals, if receive infrared touching signals and electromagnetic induction signal simultaneously, then execution in step 303; If receive only infrared touching signals, then obtain touch information according to said infrared touching signals;
In this step, when the user used time writer that contact panel 1 is carried out touch control operation, control module can receive electromagnetic induction signal and infrared touching signals simultaneously, and then execution in step 33.
Use the touch object of other types as the user; When carrying out touch control operation like finger; The infrared ray that covers on the contact panel is blocked by touch object, owing to can not produce electromagnetic induction signal, so control module can only receive infrared touching signals; And obtain touch information according to this infrared touching signals, confirm the position of touch object.
Step 303: according to the priority that is provided with in advance, the touching signals that priority is high is handled, obtained the touch information of touch object.
In this step, the priority that electromagnetic induction signal is set is higher than infrared touching signals, and then control module is preferentially handled electromagnetic induction signal, and obtains touch information and send to computing machine, and the touching signals that priority is low is not then handled.
The embodiment of the invention provides the method for a kind of pair of touch-control location, not only both can use time writer to carry out hi-Fix through the electromagnetism touch technology; And; Can also utilize finger to wait other touch objects to carry out touch control operation through infrared touch technology; Have touching the advantage of object less-restrictive, avoided losing the problem that to utilize the electromagnetism touch technology to position, widened the scope of application of contactor control device because of time writer.
The above; Be merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; Can expect easily changing or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by said protection domain with claim.
