Control method, control device, storage medium and remote controller

Abstract

The invention provides a control method of a remote controller. The remote controller includes a control chip internally provided with a high frequency oscillator and a low frequency oscillator. The control method includes the following steps: controlling the high frequency oscillator and the low frequency oscillator to be in an off state and an on state respectively, and setting a wake-up time interval; controlling to start the high frequency oscillator and obtaining the initial timing time when the timing time of the low frequency oscillator reaches the wake-up time interval, and obtaining the current timing time of the high frequency oscillator when the timing time of the low frequency oscillator after the starting of the high frequency oscillator reaches a calibration time interval; determining the current deviation time of the low frequency oscillator according to the current timing time, the initial timing time and the calibration time interval; adding the current deviation timeto a historical cumulative deviation time to obtain the current accumulative deviation time; and determining whether to calibrate the preset timing time of the remote controller or not according to the current accumulative deviation time. The invention also provides a control device of the remote controller, a computer readable storage medium, and the remote controller.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, in particular to a control method for a remote controller, a control device for a remote controller, a computer-readable storage medium and a remote controller. Background technique [0002] At present, the remote controllers with liquid crystal displays of most household appliances need to enter the sleep mode during static work due to their low power consumption requirements. low frequency oscillating circuit. However, due to the large error of the low-frequency oscillation circuit inside the MCU, the error is generally more than 10%, and sometimes it can reach 15%. Therefore, in order to reduce the timing error, the remote controller with a longer time timing function will be connected with an external crystal oscillator, such as The 32.768K crystal oscillator has the advantage of high precision, but has the disadvantage of taking up a lot of space due to its l...
