Abstract

The invention discloses a radio frequency signal awakening method and device, electronic equipment and a storage medium. The method comprises the following steps: receiving a radio frequency signal; carrying out band-pass filtering on the radio frequency signal, and reserving a signal in a preset frequency band; performing amplification and detection on the signal in the reserved preset frequencyband, and outputting an enhancement signal capable of exciting a circuit module to be awakened; and shaping the enhanced signal, and outputting a wake-up signal which can be identified by a circuit module to be waken up. According to the invention, the standby state of the electronic product is adjusted to a low-power-consumption dormant state; energy loss of batteries is reduced, when needing towork, the circuit module to be awakened is stimulated to enter a working state from the low-power-consumption dormant state through radio frequency signal awakening. According to the technical scheme,the single use time of the electronic product can be prolonged without increasing the battery capacity, ultra-long standby is achieved, the use pleasure of a user can be improved to the maximum extent, and the electronic product is stable, reliable, good in energy-saving effect, high in practicability and wide in application range.

Description

Technical field [0001] The present invention relates to the field of electrical technology, in particular to a radio frequency signal wake-up method, device, electronic equipment and storage medium. Background technique [0002] At present, with the popularization of intelligent electronic products, more and more electronic products in life begin to use built-in batteries for power supply. However, in order to improve user experience and portability, some electronic products are getting smaller and smaller. However, the battery energy storage is directly proportional to the volume of the electronic product. When the volume is certain, the battery storage energy cannot be increased, and frequent charging or replacement of the battery will seriously reduce the user's favorability. [0003] Among the many electronic products, some electronic products do not need to work continuously, but are in the working state during some time periods and are in the standby state during other time ...
