The first processor 50 analyzes the waveform of the received audio to determine whether the audio belongs to the sound emitted by the domestic dog. Step 03 is performed when the first processor 50 determines that the audio belongs to the sound of the dog.

Step 03: The first processor 50 determines whether the received audio is abnormal audio. The first processor 50 compares the received audio volume with the audio threshold, when the received audio tone When the amount does not exceed the audio threshold, it is determined to be normal audio; when the received audio volume exceeds the audio threshold, it is determined to be abnormal audio.

In step 04, the camera device 20 records an image and transmits the image to the portable electronic device 200 by the first wireless communication device 40. The portable electronic device 200 receives the recorded image by the second wireless communication module 140 and transmits the image to the second processor 120 and the application 150.

Step 05: The second processor 120 analyzes the face feature in the received image, and compares the analyzed face feature with the contact face data in the storage unit 130 to identify the person in the image. Whether it is a contact person. When the face feature in the image is successfully matched with the stored contact face data, the second processor 120 determines that the person in the image is a contact, and performs step 06; when the face feature in the image is in contact with the store If the matching of the face data is unsuccessful, the second processor 120 determines that the person in the image is not a contact, and performs step 08.

Step 06: The portable electronic device 200 transmits a noise cancellation command to the wearable electronic device 100. The second processor 120 transmits the noise cancellation command to the portable electronic device 200 by using the second wireless communication module 140, and the first wireless communication device 40 receives the noise cancellation command and A noise cancellation command is transmitted to the first processor 40.

In step 07, the speaker 30 sends out the cancellation of the audio for a predetermined time. The first processor 40 controls the speaker 30 to issue the canceled audio for a predetermined time according to the received noise cancellation command. In this embodiment, the waveform of the canceled audio is the reverse wave of the waveform of the barking or squeaking audio of the domestic dog. The predetermined time for releasing the audio cancellation may be set by the application 150 installed by the portable electronic device 200. After the cancellation of the audio message reaches the predetermined time, the process returns to step 02 to continue detecting the sound of the domestic dog.

In step 08, the alarm device 160 sends an alarm signal. In this embodiment, the alarm signal may be sound, flash, vibration, etc., to remind the user that an abnormal situation has occurred. In addition, the alarm signal can also display information or images by the application 150 to remind the user. It can be understood that the alarm device 160 can also alert the user's neighbors and community management personnel by issuing an alarm signal.

In step 09, the application 150 displays the image recorded by the camera device 20, and the user manually determines, by the application program 150, whether the person in the image is a stranger or whether the environment in the image is an abnormal environment. If the user determines that the person in the image is an acquaintance or the environment is a normal environment, step 06 is performed; if the user determines that the person in the image is a stranger or the environment is an abnormal environment, step 11 is performed. The abnormal environment may be an environment caused by a natural disaster such as a flood, a fire, or an earthquake.

In step 11, the user considers whether to perform the next step of the alarm or the like according to the specific situation.

In another embodiment, step 03 may be omitted, that is, when the sound receiving device 10 records the sound emitted by the domestic dog, the image is directly recorded by the camera device 20 and the image is transmitted to the portable device. The electronic device 200 performs the next determination.

In another embodiment, the step of comparing the analyzed facial features with the contact face data in the storage unit 130 is set in the cloud server processing, and the storage unit 130 does not need to store the contact person. The face data is stored by the cloud server to reduce the memory burden of the portable electronic device 200. The portable electronic device 200 can transmit the analyzed facial features to the cloud server for the comparison.

In another embodiment, step 05 can be omitted, and step 08 is directly executed, that is, the user directly determines whether the person in the image is a stranger or the environment is an abnormal environment by using the image, without performing face feature comparison. Programs to speed up the process and increase the speed of response.

In another embodiment, the user can actively issue the noise cancellation command by the application 150 to cause the speaker 30 to emit the cancellation audio. In this embodiment, it can cope with, for example, In the environment where the house and the domestic dog are in the same place or outside, the domestic dog is screamed or barked by sudden shocks such as firecrackers. The user directly understands the situation and takes the initiative to issue a noise elimination order to eliminate the domestication. Howling or barking from a dog.
