Key sampling and filtering method and air conditioner

Abstract

The invention provides a key sampling and filtering method. The method comprises the steps that a key sampling module performs key AD value sampling at a certain time interval; key AD acquisition values which are continuously acquired for N times are taken as a group of data for filtering processing, and the data obtained after the filtering processing is assigned to key AD cache values; key AD cache values and AD cache backup values are obtained; the key AD cache values are compared with the AD cache backup values, the key AD cache values are assigned to key AD effective values and the AD cache backup values when the difference between the key AD cache values and the AD cache backup values is less than or equal to H, otherwise, the key AD effective values are not changed, and the key AD cache values are assigned to the AD cache backup values; key function processing is carried out at a certain time interval according to the key AD effective values, and related key actions are executed. The invention further provides an air conditioner for executing the key sampling and filtering method. Reliable key touch is ensured, and the problems of insensitivity, false triggering and easy external interference of keys are solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a button sampling and filtering method and an air conditioner. Background technique [0002] The display screens of general air-conditioning cabinets have touch buttons, which can be used to switch on and off the air conditioner, adjust the temperature, adjust the wind speed, etc., which is a more convenient control method besides the remote control. The buttons on the display screen generally use the AD sampling processing method. In actual use, sometimes users will encounter problems such as insensitivity to touch, false triggering of buttons, and susceptibility to external interference, which will lead to poor user experience and lead to the above problems. The reason is that the sampling filter processing of the display screen keys is unreasonable or unsuitable for the use environment. In view of this problem, this application is proposed.
