AI Technical Summary

Technical Problem

The prior art cannot accurately detect whether a particular audio signal is played correctly, especially in an on-board environment. For functional safety-related audio signals, existing methods cannot distinguish whether a particular audio stream is played correctly.

Method used

By mixing the first audio signal to be detected with the second audio signal in a preset frequency band, and collecting the mixed signal, the playback status of the first audio signal is determined, thereby realizing the detection of whether the audio signal is played correctly.

Benefits of technology

This method can accurately detect the playback state of the first audio signal, avoid interference from the second audio signal on the playback content and effect of the first audio signal, and improve the accuracy of detection.

Abstract

The embodiment of the invention discloses a method and system for detecting the playing state of audio playing equipment, a medium and the equipment, and the method comprises the steps: determining a first audio signal of the audio playing equipment; determining a second audio signal in a preset frequency band according to the first audio signal; playing a signal obtained by mixing the first audio signal and the second audio signal through the audio playing device; collecting a mixed signal played by the audio playing equipment to obtain a third audio signal; determining a playing state of the first audio signal according to the third audio signal; and based on the playing state, controlling the audio playing device to execute a corresponding operation. According to the embodiment of the invention, the playing state of the first audio signal is determined based on the third audio signal, and the second audio signal is the audio signal which is determined based on the first audio signal and is in the preset frequency band, so that the accuracy of detecting the playing state of the first audio signal is improved.
