Control method, control device, storage medium and remote controller

Abstract

The invention provides a control method of a remote controller. The remote controller comprises a control chip with a built-in high frequency oscillator and a built-in low frequency oscillator; the control method comprises the following steps: setting error correction reference time; controlling the simultaneous starting of the high frequency oscillator and the low frequency oscillator so as to respectively begin timing; when the time-keeping time of the high frequency oscillator achieves the error correction reference time, acquiring the current time-keeping time of the low frequency oscillator; and calibrating the time-keeping time of the low frequency oscillator according to the error correction reference time and the current time-keeping time. Correspondingly, the invention further provides a control device of the remote controller, a computer readable storage medium and the remote controller. Through the technical scheme provided by the invention, the timing error of the low frequency oscillator built in the remote controller circuit can be effectively reduced under the situation of eliminating an external crystal oscillator or ceramic oscillator on the remote controller circuit.

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 control chip of the remote control with liquid crystal display of most household appliances has a built-in high-frequency oscillator (with an error of about ±1%) and a low-frequency oscillator (with an error of about ±10% to ±15%). After the controller enters the low-power mode, it is necessary to turn off the high-frequency oscillator to save power, and only keep the low-frequency oscillator running, that is, the low-frequency oscillator generates a reference time base when the control chip of the remote control works in low-power mode as the remote control Time or timer timing. However, due to the relatively large error of the built-in low-frequency oscillato...

Problems solved by technology

However, due to the relatively large error of the built-in low-frequency oscillator in the chip, an external low-frequency oscillator is generally connected to the circuit of the remote control, that is, the circuit of the control chip of the remote control has one or two crystal oscillators or ceramic oscillators, one of which is The oscillator is a low-frequency oscillator. In order to compensate for the timing error of the built-in low-frequency oscillator, the external low-frequency oscillator generates a reference time base when the control chip of the remote control works in low-power mode as the remote control time or Timing timing has the advantage of high precision, but it has the disadvantage of large volume resulting in a large space occupation, and in the production process of the remote control, an additional external oscillator will also affect the production efficiency and production cost optimization of the product
