Technical field
The present invention relates to a kind of computer realm, specially a touch-screen system.
Background technology
Existing touch-screen system, it is not easy to install, it is therefore desirable to install and mostly dispatching from the factory in the equipment of touch-screen system
When by touch-screen system be arranged on equipment on.Terminal client is caused for, either with or without touch-screen system, not selected in equipment
Selecting property can be sayed.
Some equipment are assembled with touch-screen system in advance, but client and need not, such case is for client and production
All it is a kind of waste for business.Some equipment are in advance without assembling touch-screen system, but client needs to use touch-screen system
System, in this case, client may select other products, or need to spend higher cost to transform equipment, this
Kind situation is also all unfavorable to client and manufacturer, and therefore manufacturer may lose client, therefore client may spend higher.
If wireless optical touch-screen system will solve above-mentioned contradiction.Make that touch-screen system can be assembled in equipment easily
System or dismounting touch-screen system, to meet the needs of client, and then meet the interests between client and manufacturer.
Existing image interactive technology, virtual laser keyboard technique, optical touch screen systems technology, and laser remote-controlled skill
Art, certain technical foundation can be provided for wireless optical touch-screen system.
The content of the invention
It is an object of the present invention to provide wireless optical touch-screen system, in that context it may be convenient to it is installed on relevant device, with
It is easy to touch-screen system function unrestricted choice.
The present invention also aims to, there is provided several purposes of wireless optical touch-screen system.
Technical problem solved by the invention can be realized using following technical scheme：
Wireless optical touch-screen system, including microprocessor module, the communication to be communicated with the microprocessor module
Module, the touch location detection module of detected touch point position, it is characterised in that also be easy to touch the wireless optical including one
Touch the fixing device that screen system is fixed on screen side or corner.The fixing device is convenient for consolidating for installation and removal for one
Determine device.The wireless optical touch-screen system includes a housing, the communication module and touch location detection module peace
In the housing.
The touch location detection module, for a touch location detection mould for utilizing optical characteristics detected touch point position
Block.
The fixing device can be the fixing device fixed using sucker, the fixing device fixed by magnetic force, pass through
Glue fix fixing device, electrostatic fix fixing device, by clip fix fixing device, by grafting by way of
Fixed fixing device, or pass through neck and the fixing device of buckle clamping.Some fixing devices are, it is necessary to the equipment connected
On have matched part.Than if any smooth part, being easy to sucker suction；Than if any the insulation division for being easy to Electrostatic Absorption
Point, or the part of storage electric charge；Than if any the projection for being easy to clip to bite；Than if any the slot for being easy to grafting；Than if any being easy to
The neck or buckle of grafting.
Also include a touch point calibration module for being used to calibrate the wireless optical touch-screen system.
The touch location detection module, can be used using existing virtual laser keyboard, for determining to click on
Position, the touch location detection module of the structural principle of click location detection module.What existing virtual laser keyboard used
Click location detection module, preferably click location can be detected, and be accurately positioned.Can be with relatively straightforward by it
Applied to the present invention, detection positioning is carried out to touch point.The touch point of the click location of virtual laser keyboard and the present invention, essence
It is identical.Therefore the touch location of the structural principle of the click location detection module for being used using existing virtual laser keyboard
The concrete structure of detection module, is no longer described in detail.
The touch location detection module, including an infrared emitter, an IR signal reception module, an infrared image are determined
Position device；The IR signal reception module connects the infrared image positioner.
The touch point calibration module can be the calibrating principle of the calibration module used using existing touch-screen system
Calibration module.
The present invention is to perceive touch point position by optical signal.Resistive touchscreen system is to perceive to touch by resistance variations
Touch a position.The mode that both perceive touch point position is different, but after touch point position is perceived, will realize to touch
The position of point is converted into the work of the cursor on the display screen of connected device, can be considered as identical, institute in both this point
The touch point calibration module can be applied to relatively straightforward with the calibrating principle of the calibration module of resistive touchscreen system.
Similarly the calibrating principle of the calibration module of other existing touch-screen systems relatively straightforward can also be applied to the touch point
Calibration module.
The touch point calibration module is that module delimited in a touch area with delimitation touch area function.In the present invention
The touch location detection module used in technical scheme is stated, different from used by existing touch-screen system, itself does not have
There is very clear and definite touch area boundary.In order to the clear and definite touch area of boundary needed, using the Petting Area
Domain delimit module and touch area delimited.The touch point calibration module be to delimiting the realization of touch area function in hardware
On can be based on, or even be based entirely on common touch point calibration module.The microprocessor module makes to connect first to set
Anchor point is presented respectively on four angles of standby display screen, using the anchor point as region division index point, make touch point with
