The invention provides a respirator speaker state detection method and device. The detection method includes the following steps: when a respirator is started up, starting a test tone playing thread of the speaker, and starting a test tone recording thread of the speaker; generating a test tone recording file when test tone of the speaker is recorded; subjecting audio data in the test tone recording file to short-time Fourier transform, and subjecting results obtained after short-time Fourier transform to audio matching analysis so as to judge whether the speaker is in a failure state or not. By the respirator speaker state detection method and device, the audio data in the test tone recording file are subjected to short-time Fourier transform and the results obtained after transform are subjected to audio matching analysis so as to judge whether the speaker is in the failure state or not, so that cost is lowered, flexibility in hardware layout is improved, and implementation is simple.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a detection method and a detection device for a horn state of a ventilator. Background technique [0002] In the ventilator, since the alarm method of the ventilator mainly prompts the user through two ways of visual alarm and auditory alarm, and the auditory alarm mainly uses the horn of the ventilator to play the alarm sound to remind the user, so every time the ventilator is used , you need to check the status of the horn first to confirm that the horn is in a normal state, so as to ensure the normal operation of the ventilator. [0003] In the related art, the method for detecting the state of the speaker of the ventilator is generally implemented by having a power amplifier chip for detecting the failure state of the speaker to determine whether the speaker is in the failure state. However, detecting the speaker status through the chip requires a power amplifier chi...
