Problems solved by technology

Optical network design is the first step in the development of infrared touch products. In the design process, it is often necessary to start over and over again. Each time, a lot of time and energy are required for design and evaluation, which seriously affects the development cycle, consumes a lot of time and energy, and easy to make mistakes
[0004] The present invention aims to solve the problem that drawing is difficult and error-prone due to the large number of rays, and provides a fast and accurate drawing method

Embodiment Construction

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0028] Such as figure 1 As shown, an optical network drawing method of an infrared touch frame includes the following steps:

[0029] S1: Create a parameter input module, a transceiver mode selection module, a CAD line drawing instruction generation module, a lamp serial number instruction generation module, and a lamp transceiver index generation module in the Excel table through the VBA programming language;

[0030] The parameter input module includes the following parameters:

[0031] 1) The length and width of the input infrared touch frame and the retraction distance of the lamp tube;

[0032] 2) The coordinates of the input transmitting light and receiving light;

[0033] Figure 5 In a specific embodimen...

Abstract

The invention relates to an optical network drawing method of an infrared touch frame, which can obtain an accurate optical network CAD drawing within a few minutes by inputting coordinates and selecting parameters, so that the drawing time is greatly shortened, and the drawing accuracy is improved. Compared with the prior art, the method is advantageous in that a tool combination of VBA+Excel+AutoCAD is adopted, drawing is conducted through codes, manpower is replaced, the method is different from existing manual drawing, and the drawing speed and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of infrared touch frame devices, in particular to an optical network drawing method of an infrared touch frame. Background technique [0002] The infrared touch frame detects the position of the touch point by whether the light between the emitting light and the receiving light is blocked. The combination of these lights forms a dense optical network. The design of the infrared touch frame needs to draw the optical network to evaluate the rationality of the design , the current implementation principle of the infrared touch frame is mainly that the emitting light emits multiple rays of light to the receiving light. When the light is blocked by the touch object, the light is blocked, and a touch area is formed between the blocked light rays. Two of the directions are used to determine the suspected The contact area, and then use light from other directions to check the suspected area, remove false points and ...
