The invention relates to the technical field of data processing, and discloses a gain adjustment method and device of an infrared touch screen, equipment and a storage medium. The method comprises the following steps: if a preset startup instruction is received, judging whether a received scanning mark is set or not; if the received scanning mark is set, modifying the received scanning mark to be not set, and scanning and calculating a signal average value of infrared signals emitted by an infrared emission lamp group to an infrared receiving lamp group corresponding to the infrared emission lamp group in the infrared touch screen; according to the signal average value, a preset receiving threshold value and a gain declinable mark, the receiving gain of the infrared receiving lamp group is adjusted through a receiving gain adjusting method; if the emission scanning mark is not set, judging whether the emission scanning mark is set or not; if the signal average value is set, the emission scanning mark is modified to be not set, and the emission gain of the infrared emission lamp set is adjusted through an emission gain adjusting method according to the signal average value and the preset emission threshold value. The embodiment of the invention can realize stable gain adjustment and improve the gain adjustment efficiency.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a gain adjustment method, device, equipment and storage medium of an infrared touch screen. Background technique [0002] The infrared touch screen is an electronic system installed on the surface of the display device and used together with the display device to detect whether there is a touch in the display area and determine the touch position. Compared with the infrared touch screen, it realizes product features such as saving space, diversifying user interface methods, more beautiful design, and product differentiation. When the infrared touch screen works in different environments, the infrared signal value will change with changes in the environment such as light and temperature, so it is necessary to set different gains for different environments. The existing gain adjustment methods mainly have the following problems: (1 ) Since it ...
