Key pressure calibration method and system, detection method and storage medium

The invention provides a key pressure calibration method and system, a detection method and a storage medium, and the calibration method mainly comprises the steps: taking a target test value of a tested key of a test product under a preset pressing pressure as a dependent variable, taking a reference value of the tested key of the test product as an independent variable, respectively substituting the dependent variable and the independent variable into a preset linear relation, and calculating a key pressure value of the tested key of the test product; obtaining a target linear relational expression of the reference value and the target test value of the tested key, calculating a target calibration value of each key according to the optimized target linear relational expression, and recording and storing the target calibration value as a calibration threshold value; and after one-time calibration self-inspection is carried out on any key of the test product, the preset parameters of the calibration device of
