Problems solved by technology

At present, the touch screen using infrared tubes mainly has the following defects: due to the different numbers of infrared tubes of different sizes, the control procedures of infrared touch screens of different sizes are also different
There are still different versions of programs for different types of touch screens, but the research and development stage has been slightly improved compared to the original ones, and the problems in the production process and follow-up management have not been solved.

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 It is a flow chart of the infrared tube detection method of the touch screen of the present invention, including:

[0023] S101: Send out an excitation detection signal, and detect a preset number of K infrared tubes in the infrared tube module within each pulse period.

[0024] It should be noted that the main control module sends an excitation detection signal to the infrared tube module. The excitation detection signal is a level signal. Specifically, when the initial state of the infrared tube module is low level, the excitation detection signal is high level; when the initial state of the infrared tube module is high level, the excitation detection signal is low level .

[0025] When the infrared tube module receives the excitation detecti...

Abstract

The invention discloses an infrared tube detection method and device of a touch screen. The method comprises the following steps: transmitting an excited detection signal, and detecting preset K infrared tubes in an infrared tube module in a pulse cycle; transmitting a feedback detection signal by the infrared tube module when the last infrared tube is detected; and according to M pulse cycles experiencing between the process of transmitting the excited detection signal and the process of receiving the feedback detection signal, counting the quantity of infrared counter tubes. By the invention, the touch screen of different dimension types can automatically detect the infrared counter tubes to obtain the quantity of the infrared counter tubes, thus quickening the research and development efficiency and the production flow of a product.

Description

technical field [0001] The invention relates to an infrared tube detection technology, in particular to a touch screen infrared tube detection method and device. Background technique [0002] Infrared pair tube is the general term for when the infrared emitting tube and the photosensitive receiving tube, or the infrared receiving tube, or the infrared receiving head are used together. At present, the touch screens using infrared tubes mainly have the following defects: due to the different numbers of infrared tubes of different sizes, the control procedures of infrared touch screens of different sizes are also different. Therefore, for touch screens of different sizes, corresponding industrial control programs need to be configured. The interfaces of these industrial control programs are difficult to be compatible, which brings a lot of inconvenience to the management of product production and R&D. In particular, with the upgrading of touch screen products, there are more a...
