Abstract
The invention relates to a random skipping type local area detecting locating method for an infrared screen. The infrared screen is provided with an infrared transmitting module, an infrared receiving module and an infrared master control module. In the locating process, firstly, all pipes are divided into a plurality of sets with eight pairs of pipes as a set, one pipe in each set is scanned in a skipping mode, the scanning sequence for the sets is 1-4-7-2-5-8-3-6, and once the fact that one pair of pipes is touched is detected, a small local area is expanded left and right with the pipes as a center for scanning. The random skipping type local area detecting locating method for the infrared screen has the advantages of being capable of fast locating the local area, improving scanning speed and improving the response speed of the infrared screen, enabling touch not to be delayed and lagged and the like.
Description
Technical field
The present invention relates to touch screen technology field, relate in particular to a kind of infrared screen random skip formula and detect local area localization method.
Background technology
Traditional infrared touch panel is that a circuit board housing is installed before display, by both sides infrared transmitter and infrared receiver, formed, be mainly to detect touch by the infrared ray matrix of intersection anyhow densely covered in X-axis and Y-axis, and infrared screen is to touch location based on side by side progressively scanning every a pair of infrared tube mostly at present; Suppose altogether with m infrared tube, be t every pair of infrared tube sweep time, and the single pass time used is m * t.Along with the increase of size, infrared tube is counted m also to be increased thereupon, and run-down spent time m * t is just more of a specified duration like this, causes like this effect of real experiences to have kind of a sensation that touches hysteresis; Therefore, how to address the above problem and become problem demanding prompt solution.
Summary of the invention
The present invention provides a kind of and responds fast, to touch the features such as hysteresis delay not, sweep velocity be fast infrared screen random skip formula and detect local area localization method for addressing the above problem.
The technical scheme that the present invention addresses the above problem is: a kind of infrared screen random skip formula involved in the present invention detects local area localization method, it is characterized in that: comprise the following steps:
(1) receiving tube of infrared screen is become to some groups according to eight pairs of Guan Weiyi components;
(2) start infrared scan, set up infrared transmission module, the signal that detects each receiving tube all can be received;
(3) start to scan, scanning is each time for great-jump-forward again, and scan mode is some receiving tubes of all groups of scanning, and scanning sequency is 1-4-7-2-5-8-3-6 in every group;
(4) detect data, when receiver module detects some receiving tubes and is touched, centered by this pipe, open to the left and right immediately and expand a local zonule and scan, complete the location of whole regional area.
The invention has the beneficial effects as follows:
1, adopt great-jump-forward scanning method can locate fast the position of regional area;
2, promoted the lifting of touching technique, made user obtain better experience effect;
3, sweep velocity is fast, can not produce and touch the phenomenon lagging behind.
[accompanying drawing explanation]
Fig. 1 is perspective view of the present invention.
[embodiment]
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
A kind of infrared screen random skip formula involved in the present invention detects local area localization method, wherein: comprise the following steps:
(1) receiving tube of infrared screen 1 is become to some groups according to eight pairs of Guan Weiyi components;
(2) signal that detects each receiving tube all can be received;
(3) start infrared scan, set up infrared transmission module;
(4) start to scan, scanning is each time for great-jump-forward again, and scan mode is some receiving tubes of all groups of scanning, and scanning sequency is 1-4-7-2-5-8-3-6 in every group;
(5) detect data, when infrared receiving module detects some receiving tubes and is touched, centered by this pipe, open to the left and right immediately and expand a local zonule and scan, complete the location of whole regional area.
Infrared touch panel of the present invention comprises infrared transmission module 11, infrared receiving module 12 and main control module 13, infrared transmission module 11 is distributed in infrared screen 1 left side, infrared receiving module 12 is distributed in infrared screen 1 right side, infrared transmission module 11 is all connected with main control module 13 with infrared receiving module 12, the infrared signal of infrared transmission module 11 transmitting can cover whole infrared receiving module, and main control module 13 is mainly connected with external communication module and transfers data to main frame.
Infrared screen transmits and receives signal formation X, Y-axis formation intersection infrared ray matrix anyhow, touch location for detection of user, traditional technology is to scan successively in order after infrared emitting, when having any object to shelter from infrared ray propagation, receiver can can't detect corresponding Infrared at certain specific time point, therefore, system can be judged the existence that there is touch point in a certain region, thereby makes corresponding reaction; The present invention divides into groups receiving tube according to eight pairs of Guan Weiyi groups, scan again, scanning process is carried out in the mode of great-jump-forward, when infrared signal is when some receiving tubes are subject to stopping, centered by this pipe, propagating out immediately a regional area to the left and right scans, guaranteed so can not postpone after infrared screen is located soon, touched, the scan method of great-jump-forward has been accelerated single pass speed used simultaneously.
In sum, the present invention is as instructions and diagramatic content, makes actual sample and through repeatedly use test, from the effect of use test, provable the present invention can reach the object that it is expected, practical value is unquestionable.Above illustrated embodiment is only used for conveniently illustrating the present invention, not the present invention is done to any pro forma restriction, under any, in technical field, have and conventionally know the knowledgeable, if within not departing from the scope of technical characterictic that the present invention puies forward, utilize disclosed technology contents to do the local equivalent embodiment that changes or modify, and do not depart from technical characterictic content of the present invention, all still belong in the scope of the technology of the present invention feature.
