Abstract

The invention relates to an information transmission method and device and a storage medium. The information transmission method is applied to an ultrasonic transmitting end, and comprises the following steps: encoding information to be transmitted to obtain an ultrasonic encoding signal; obtaining an ultrasonic transmission signal based on the ultrasonic coded signal and an ultrasonic wake-up signal, wherein the ultrasonic wake-up signal is used for waking up an ultrasonic receiving end to decode the ultrasonic coded signal; and transmitting the ultrasonic transmission signal to an ultrasonicreceiving end. According to the information transmission method disclosed by the invention, on the premise of ensuring that the ultrasonic receiving end can decode in time, the decoding device in theultrasonic receiving end does not need to be in a working state all the time, so the power consumption of the ultrasonic receiving end is reduced, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the technical field of information transmission, and in particular, to an information transmission method, device and storage medium. Background technique [0002] In short-distance wireless information transmission, transmission based on ultrasonic waves is a low-cost solution. [0003] In the process of information transmission based on ultrasonic waves, it is necessary to encode the information to be transmitted into ultrasonic data, and then decode the ultrasonic data into information to be transmitted. [0004] In order to be able to decode the ultrasonic data in time, the decoding device needs to be in working condition all the time, which will increase a large amount of power consumption of the decoding device; Users have a poor user experience. Contents of the invention [0005] In order to overcome the problems existing in related technologies, the present disclosure provides an information transmission me...
