Abstract

The invention discloses a simulation method and system of an infrared touch screen. The method comprises the steps of generating an infrared light path diagram according to the distribution condition of infrared photoelectric sensors which are designed in advance, performing statistics on the density degree of infrared rays in the light path diagram, judging whether the current design is qualified according to statistical results, adjusting the design till the design is qualified if the design is unqualified, so as to obtain a design scheme meeting performance requirements, performing hardware and PCB (printed circuit board) design according to the scheme, and producing samples. Therefore, the method and the system can be used for greatly improving the design success rate of the scheme, simultaneously rapidly judging the feasibility of the design scheme and accelerating the research of a recognition algorithm, and the whole research and development process is promoted.

Description

technical field [0001] The invention relates to the technical field of infrared touch, in particular to a method and system for simulating an infrared touch screen. Background technique [0002] The working principle of the infrared touch screen is: use the infrared matrix densely distributed in the X and Y directions to detect and locate the user's touch. Usually, an infrared touch screen installs an outer frame in front of the display, and arranges infrared emitting tubes and infrared receiving tubes on the four sides of the screen by the circuit board hidden in the outer frame, forming a horizontal and vertical crossing infrared matrix one by one. When the user touches the screen, the finger will block multiple infrared rays passing through the position, so the position of the touch point on the screen can be judged. [0003] At present, the research and development process of infrared touch screen is as follows: after the R & D personnel think about the LED lamp tube an...
