Bark stopping method and a bark stopping device

A bark stopping device, comprising a shell, a circuit board, a sound collecting module, a distance detecting module and a sound wave emitting module, wherein the circuit board is fixedly connected in the shell, the sound collecting module, the distance detecting module and the sound wave emitting module are all fixedly connected to one side of the shell, the sound collecting module, the distance detecting module and the sound wave emitting module are all oriented to the outside, the sound collecting module, the distance detecting module and the sound wave emitting module are all electrically connected with the circuit board, and the circuit board is provided with a first comparing and identifying module, a second comparing and identifying module, a third comparing and identifying module, an computing module, a first judging module, a first executing module, a second judging module and a second executing module;

• the sound collecting module is configured for acquiring the current first environmental sound, second environmental sound and third environmental sound;
• the distance detecting module is configured for acquiring the first distance and the second distance of the barking dog in the current environment;
• the sound wave emitting module is configured for emitting the first driving sound wave and the second driving sound wave towards the barking dog;
• the first comparing and identifying module is configured for identifying the dog barking sound according to the first environmental sound;
• the second comparing and identifying module is configured for identifying the type of the barking dog according to the dog barking sound in combination with the pre-stored sound model;
• the third comparing and identifying module is configured for identifying the frequency of the barking sound wave according to the type of the barking dog and the dog barking sound;
• the computing module is configured for generating the first driving sound wave with the same frequency according to the frequency of the barking sound wave;
• the first judging module is configured for judging whether the first distance of the barking dog is less than the preset distance;
• the first executing module is configured for, if the first distance of the barking dog is less than the preset distance, emitting the first driving sound wave towards the barking dog;
• the second judging module is configured for judging whether the dog barking sound exists in the current second environmental sound;
• and
• the second executing module is configured for, if no dog barking sound exists in the current second environmental sound, stopping the emission of the first driving sound wave.
