Abstract

The invention provides a key detection method and system. The method comprises the steps of collecting a voltage value of a to-be-detected key in a period from pressing down to releasing according to a preset frequency so as to obtain a voltage data set corresponding to the to-be-detected key; performing curve fitting on the voltage value and the time in the voltage data set to obtain a first fitting curve; obtaining a time set in which the derivative of the first fitting curve is zero, and comparing the time set with a first preset set to obtain a first comparison result; based on the first comparison result, obtaining a positive and negative derivative set of each element in the time set in a preset range, and comparing the positive and negative derivative set with a second preset set to obtain a second comparison result; and determining the current state information of the to-be-detected key based on the first comparison result and the second comparison result. According to the invention, the current state of the key can be accurately detected, and the operation experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of keys, and more specifically, to a key detection method and system. Background technique [0002] Traditional mechanical buttons have limited service life and poor control experience, which leads to the continuous development and application of other types of replacement buttons, such as touch buttons or piezoelectric effect buttons. The signal conduction or transmission may easily cause the button to be pressed by mistake during long-term use, so that the accuracy of the button cannot be guaranteed, which affects the user experience. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a key detection method and system to solve the existing problems of low precision and poor user experience of key. [0004] The button detection method provided by the present invention includes: collecting the voltage value of the button to be detec...
