Touch screen power supply interference identification processing method

Abstract

The invention relates to a touch screen power supply interference identification processing method. Firstly, a touch screen is powered on, and node data of all channels of the touch screen are scannedand measured; analyzing, processing and converting the node data of each channel; dynamically detecting node difference data of which the full screen of the touch screen is greater than a power supply interference threshold value; the invention discloses a power interference identification mode time threshold. When the absolute value of the difference value between the channel node difference value data and the previous time node difference value data is smaller than a power supply interference identification threshold value, power supply interference identification processing is not carriedout on the touch screen; entering a power supply interference identification mode when the absolute value of the difference between the channel node difference data and the previous time node difference data is greater than a power supply interference identification threshold value; and performing power supply interference identification processing on the touch screen, establishing a power supplyinterference distribution form data model by taking time as an axis according to the channel node data, and setting a power supply interference level according to the power supply interference distribution form data model.

Description

technical field [0001] The invention relates to the technical field of navigation and industrial control power supply interference identification, in particular to a touch screen power supply interference identification processing method. Background technique [0002] Touch screen is the most acceptable computer input method for ordinary people after keyboard, mouse, tablet and voice input. With this kind of calculation, the user can operate the host computer by lightly touching the icons or text on the computer display screen with his finger, thus making the human-computer interaction more straightforward. This technology greatly facilitates users and is an attractive new multimedia interactive device. According to the working principle of the touch screen and the medium for transmitting information, the touch screen can be divided into four types: resistive type, capacitive induction type, infrared type and surface acoustic wave type. Among them, the capacitive touch scr...
