[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] The embodiment of the present application solves the problem of accurate square dance noise identification by providing a square dance noise identification and alarm device. When used, it can accurately identify the decibels of square dance, thereby performing targeted detection and ensuring that no false alarms are generated during the alarm.

[0037] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0038] When the sound type recognition unit detects ambient sound signals, it can detect different sound types, such as car horns and square dance music. When other types of sounds are detected, the waveform of the sound is identified and the noise reduction unit emits an opposite waveform to offset it. In this way, the square dance music is more clearly displayed. In this way, when the decibel detection unit is used for detection, the decibel level of the square dance can be detected more accurately.

[0039] Acoustic scene classification and sound event detection are key technologies for computational analysis of natural acoustic scenes. They are essential components for applications such as intelligent service robots, intelligent transportation, urban noise monitoring, automated assisted driving, intelligent public safety surveillance, and ecological and environmental monitoring. Acoustic scene classification is a common method for detecting sound types.

[0040] Acoustic Scene Classification (ASC) aims to classify a test recording into one of the provided predefined labels, which describe the environment in which the audio data was recorded. Acoustic Event Detection (AED) aims to detect the presence of target sound events within a continuous audio stream, such as car horns, music, the sounds of abnormal detection equipment failures, sounds from accident scenes, and the sounds of wildlife.

[0041] For example, a technical solution disclosed in publication number CN106251861B describes a method for detecting specific sound types in public places. The basic principles of detecting square dancing and other sound types in this application are basically the same.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0043] Reference Figures 1-6 A square dance noise recognition and alarm device includes a decibel detection unit 10 installed in a housing 20, with one side of the decibel detection unit 10 passing through a side wall of the housing 20;

[0044] The central control unit 11 is installed in the housing 20;

[0045] The alarm unit 12 is installed in the housing 20;

[0046] The sound type recognition unit 13 is installed in the housing 20 and is used to detect the sound type of the surrounding environment;

[0047] It also includes a noise reduction unit 14, which is installed in the shell 20 and is used to emit adjusted sound waves and is electrically connected to the central control unit 11; the noise reduction unit 14 includes: a speaker for emitting sound waves; and a waveform adjustment unit for adjusting the waveform of the sound waves emitted by the speaker.

[0048] The principle is similar to that of noise-canceling headphones. The active noise reduction function is to generate an anti-phase sound wave equal to the external noise through the noise reduction system, neutralizing the noise and thus achieving the noise reduction effect. In this way, the decibel detection unit 10 can more clearly detect the type and decibel level of the sound, thereby more accurately measuring the sound level of square dancing.

[0049] The noise reduction unit 14 is installed in the housing 20 and is used to emit sound waves of a specific waveform;

[0050] The central control unit 11 is electrically connected to the decibel detection unit 10 , the alarm unit 12 , the sound type recognition unit 13 , and the noise reduction unit 14 .

[0051] In a further embodiment, a detachable mesh cover 21 is installed at the front end of the housing 20 , and the mesh cover 21 covers the decibel detection unit 10 and the noise reduction unit 14 .

[0052] The mesh cover 21 can protect the decibel detection unit 10 and the noise reduction unit 14 and maintain their working effects.

[0053] In a further embodiment, a rain shield 22 is installed on the upper side wall of the shell 20 . The four sides of the rain shield 22 are arranged to be arc-shaped, and the rain shield 22 wraps the upper side wall of the shell 20 .

[0054] The rain shield 22 can shield various electrical components in the housing 20 , so that even when there is heavy rain, the various electrical components inside the device can still be used safely and will not be easily damaged by rain.

[0055] In a further embodiment, a bracket 23 is installed in the housing 20 , the central control unit 11 and the voice type recognition unit 13 are both installed on the bracket 23 , and the bracket 23 is configured to be hollow.

[0056] The central control unit 11 and the sound type recognition unit 13 can be stably mounted by the bracket 23. Moreover, the hollow setting facilitates heat dissipation.

[0057] In a further embodiment, a detachable power storage unit 24 is further provided in the housing 20 , and the power storage unit 24 is used to supply power to the central control unit 11 , the decibel detection unit 10 , the alarm unit 12 , the sound type recognition unit 13 and the noise reduction unit 14 .

[0058] The detachable power storage unit 24 makes the entire device easy to use without the need for an external power supply and can be used whenever and wherever needed.

[0059] In a further embodiment, a take-out opening corresponding to the position of the power storage unit 24 is opened on the rear side of the housing 20 , a protection door 30 is provided on the take-out opening, and a lock 31 is installed on the protection door 30 .

[0060] The power storage unit 24 can be quickly replaced by opening the lock 31 and the protective door 30. The power storage unit 24 can be a lithium battery or the like.

[0061] In a further embodiment, an elastic member 32 is installed on the side wall of the protection door 30 , and the elastic member 32 is in contact with the power storage unit 24 . The elastic member 32 is configured to be in a compressed state.

[0062] The rebound force of the elastic member 32 can ensure that the power supply of the power storage unit 24 is sufficiently stable, and there will be no poor contact even if it is shaken.

[0063] In a further embodiment, a clamp 33 is provided on the protection door 30 .

[0064] The entire device can be easily installed on a fixed object using the clamp 33.

[0065] During use, the decibel detection unit 10 can detect the decibel level of the surrounding environment. When the decibel level exceeds a preset value, a signal can be sent to the alarm unit 12 through the hollow control unit, causing the alarm unit 12 to issue an alarm message. The alarm message can be sound and light information to directly stimulate people around, or it can be an alarm message to surrounding police stations or patrol officers to remind the police station staff that there is a large square dance noise around.

[0066] In the process of identifying square dance music, different sound types and waveforms can be identified through the sound type recognition unit 13, and the noise reduction unit 14 emits the waveforms corresponding to other types of sounds except the square dance music type. This can eliminate other types of sounds and retain the square dance sounds as much as possible. In this way, when identifying the decibels of the sound, the decibel size of the square dance music can be identified more accurately.

[0067] In summary, compared with the existing technology, the present invention has the following beneficial effects:

[0068] When identifying square dance noise, the sound type recognition unit 13 can also detect other types of noise, such as car horns, and the noise reduction unit 14 can emit sound waves opposite to other types of noise to offset them, thereby retaining the sound of square dance as much as possible. In this way, when identifying the decibel level of square dance sound, the recognition result is more accurate and the effect is more ideal.
