Patent Application
20250137840
The present invention relates to the technical field of detection equipment, in particular to a vibration sensor and a dog bark detection device.
Pet dog breeders generally encounter the phenomenon of uncontrollable barking of pet dogs. To deal with this situation, breeders usually use pet bark stoppers to stop pets from barking, but pet bark stoppers often rely on breeders to judge whether it is necessary to stop the pet dog from barking, so it is easy to make operational errors and cause the phenomenon of stopping the pet dog from barking when it is not necessary.
U.S. Pat. No. 4,947,795 discloses a bark control device and method. The bark control device detects sound through a microphone and analyzes dog barking through sound frequency and decibels, thereby achieving automatic electric shock bark stopping function. However, the elastic membrane in this vibration sensor is easily interfered by the external sound environment, especially when there are multiple pet dogs in a small range, it is easy to cause bark analysis failure, easily trigger its vibration, and thus trigger incorrect bark stopping.
U.S. Patent No. 20120048212 discloses a dog bark suppression device. The device includes a hanging device, which is equipped with a tuning fork. The tuning fork can swing freely with the device and can be swung by the dog's actions, such as those caused by barking. This causes the tuning fork to strike the inside of the device, causing the tuning fork to vibrate at its specific frequency and emit sound and vibration at that frequency. This emitted sound passes through the port to the dog's ears, thereby reducing the desire to bark and usually calming him down. However, this dog bark suppression device is easily interfered with by external factors, causing the device to make incorrect bark stopping judgments.
Therefore, it is necessary to provide a bark stopping device. This dog bark stopping device can shield the interference of external sounds, thereby improving the accuracy of the dog bark detection device monitoring, achieving accurate judgment of the dog bark detection device, and effectively preventing incorrect electric shock bark stopping situations.
The present invention provides a vibration sensor, comprising:
The present invention also provides a dog bark detection device, comprising:

As a preferred embodiment of this invention, refer to
In this embodiment, the shell 1 is a ring structure, its cross-sectional shape can be circular, elliptical or runway shaped. The runway shape is the shape of adding two semicircles at both ends of a rectangle. In some embodiments, the cross-sectional shape of the shell 1 can also be semicircular, or rectangular, or square, or triangular, and various other geometric shapes.
The shell 1 includes a vibration cavity 103, the vibration cavity 103 has a first opening end 101, and a second opening end 102. In this embodiment, the first opening end 101 and the second opening end 102 are respectively set at the upper and lower ends of the vibration cavity 103.
In other embodiments, the positions of the first opening end 101 and the second opening end 102 can be set at the left and right ends, or the front and back ends. As long as the first opening end 101 and the second opening end 102 are set at the opposite ends of the vibration cavity 103.
The vibration plate 2 can be movably set at the first opening end 101 of the vibration cavity 103. The vibration plate 2 can move relative to the vibration cavity 103. Its material is rigid, realizing that only direct mechanical vibration can cause the rigid vibration plate 2 to vibrate. In some embodiments, the material of the vibration plate 2 can be metal, or glass, or plastic, or polymer and other materials that are rigid and not easy to deform.
Vibration plate 2 is divided into two parts: upper and lower. Both connected parts are rigid plates. The upper and lower parts are respectively equipped with an insulation layer 201 and a conductive layer 202. The insulation layer 201 is located at one end far from the vibration cavity 103, that is, the upper part of the vibration plate 2. The conductive layer 202 is located at one end close to the vibration cavity 103, that is, the lower part of the vibration plate 2.
The back plate 3 is fixedly set at the second opening end 102 of the vibration cavity 103 and is spaced apart from the vibration plate 2. The back plate 3 cannot move relative to the vibration cavity 103. Its material is made of rigid conductive material. In some embodiments, the material of back plate 3 can be metal material, or alloy material, or graphite material, or conductive ceramic material.
It needs to be further explained that materials for back plate 3 are not limited to the above-mentioned materials structure. Those skilled in this field can flexibly adjust and set up materials for back plate 3 in actual applications as long as they can make materials for back plate 3 rigid conductive materials.
In this embodiment, the cross-sectional shape of the vibration plate 2 corresponds to the cross-sectional shape of the shell 1, which can be circular, elliptical, or runway shaped. The runway shape is the shape of adding two semicircles at both ends of a rectangle. The cross-sectional shape of the back plate 3 may not correspond to the cross-sectional shape of the shell 1, with the back plate 3 being set parallel to the shell 1. In some embodiments, such as when the precision requirement for the vibration sensor is not high or when the production level cannot meet the requirement, the back plate 3 may not be completely parallel to the shell 1, with their relative positions being nearly horizontal. The vibration plate 2 and back plate 3 constitute an adjustable capacitor. The up-and-down vibration of the vibration plate 2 changes the capacitance value of the adjustable capacitor. Through the change in capacitance value, the frequency and amplitude of mechanical vibration are analyzed. By comparing the obtained analysis value with the set range value, it can be judged whether pets are barking.
The support elastic element 4 is two in number, located in the vibration cavity 103, symmetrically distributed on the inner wall of the shell 1, and fits with the inner wall of the shell 1. The upper and lower ends of the support elastic element 4 are elastically abutted between the vibration plate 2 and the back plate 3 respectively. The support elastic element 4 is made of insulating material. In other embodiments, the support elastic element 4 can be configured as one or more other quantities.
Specifically, when a pet barks, the pet's throat emits sound, and the throat will cause the vibration plate 2 to vibrate. The vibration plate 2 is connected to the support elastic element 4. Under the action of elasticity, the support elastic element 4 will drive the vibration plate 2 to move along the axial direction of the vibration cavity 103 and reciprocate in the vertical direction. Therefore, the vibration sensor can receive vibration signals and then transmit them to the processor.
The structure of the vibration sensor in this invention application is similar to that of a capacitive microphone, but the vibration sensor of this invention application replaces the elastic vibration film in a capacitive microphone with a rigid vibration plate, thereby realizing that only direct mechanical vibration can cause rigid vibration plate to vibrate, and sound cannot effectively cause it to vibrate. Therefore, the vibration sensor of this invention application can shield external noise interference, thereby improving the accuracy of vibration reception and transmission.
As a preferred embodiment of this invention, in order to effectively stop pets from barking, refer to
The processing device is an electronic processing module, including a collection module, filtering module, signal amplification module, ad conversion module and programmable chip.
In this embodiment, the vibration sensor and vibration information collection module constitute a vibration detection unit. The vibration plate and back plate in the vibration sensor constitute a capacitor. The up-and-down vibration of the vibration plate will cause changes in this capacitor value. With the help of vibration information collection module, mechanical vibrations can be converted into electrical signals.
In this embodiment, various different vibration sensors can be used, including but not limited to accelerometers, optical devices, electromagnetic and capacitive sensors, contact devices, sensors, displacement sensors, piezoelectric sensors, pressure resistance devices, variable capacitors, servo devices, audio devices. The transmission of vibration can be gas, liquid or solid, including but not limited to microphones, seism phones and so on.
The filtering module and signal amplification module can filter and amplify the vibration electrical signal collected by the vibration sensor, filter out invalid signals and amplify valid signals, thereby greatly improving the recognition rate of dog barking.
The ad conversion module, also known as the analog-to-digital converter, converts analog signals into digital signals for further processing by the programmable chip.
The programmable chip performs specific program development to analyze the vibration frequency and amplitude of the vibration signal, thereby realizing the recognition of pet dog barking behavior and the analysis of barking decibels.
Specifically, in use, because the vibration plate is a rigid vibration plate, only direct mechanical vibration can cause the rigid vibration plate to vibrate, and sound cannot effectively cause it to vibrate. For example, when walking a dog in a park or on a street, you may encounter other dog groups. They may play or bark together. Other sensors such as microphones judge by sound. This will mistakenly regard other dog barks as the sound emitted by the target dog and trigger the bark stopping function. The vibration sensor of this invention application needs to judge directly contacted movements, which greatly improves accuracy.
In this embodiment, when worn, the dog bark detection device has corresponding wearables. The wearable is a detachable collar that is fixed to the pet's throat. The outer surface of the vibration plate on the vibration sensor is worn close to the position of the pet dog's neck near the throat. The outer surface of the vibration plate is in contact with the throat. Once the pet dog barks, the vibration sensor can generate continuous vibrations from the vibration plate. The collection module will then receive vibration information and convert mechanical vibrations into electrical signals through circuit conversion. The electrical signal will be transmitted to the filtering circuit module, which will filter out invalid signals from the electrical signal. Valid information is then transmitted to the amplifying circuit. The amplifying circuit module amplifies the valid signal, greatly improving the recognition rate of dog barking. Afterwards, through the ad conversion circuit module, analog signals are converted into digital signals, making it convenient for the programmable chip to further process the signal. The programmable chip, after specific program development, can analyze the vibration frequency and amplitude of the vibration signal, thereby realizing the recognition of pet dog barking behavior and the analysis of barking vibrations.
In some embodiments, the wearable can also be a foot cover. The foot cover has an opening at the upper end and is used to cover the pet's foot. The conductive electrode column is evenly distributed on the inner wall of the foot cover. In other embodiments, the wearable is a strap. The two ends of the strap are movably connected. The strap is used to wrap around and fix on the pet's limbs. The conductive electrode column is evenly distributed on the inner side of the strap. In other embodiments, the wearable is a chest and back coat. The two ends of the chest and back coat are movably connected. The chest and back coat are used to fix the pet's trunk. The conductive electrode column is evenly distributed on the inner side of the chest and back coat. The chest and back coat are detachably connected with a pull strap. A pull force sensor is set at the connection place of the pull strap and the chest and back coat. The pull force sensor is connected with the control mechanism for communication.
When a pet dog barks, the sound frequency has specificity, so it can exclude the vibration of the vibration plate on the vibration sensor caused by the pet dog's movement through vibration frequency analysis, thereby effectively improving its reliability in recognizing barking. When the vibration frequency reaches a set range value, there are evenly distributed conductive electrode columns on the inner side of the collar. The conductive electrode column communicates with the programmable chip. There is a conductive medium inside the conductive electrode column. The programmable chip will transmit electrical signals through the conductive medium of the conductive electrode column to the pet's body, causing muscle contraction and tremor in pets, thereby completing bark stopping behavior.
In other embodiments, communication between conductive electrode column and programmable chip can use any one of various communication standards, protocols and technologies, including but not limited to global system for mobile communications (GSM), enhanced data rates for GSM evolution (EDGE), high-speed downlink packet access (HSDPA), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), BLUETOOTH®, wireless fidelity (WI-FI) (FOR EXAMPLE, IEEE802.11A, IEEE802.111B, IEEE802.11G AND/OR IEEE802.11N), voice over internet protocol (VOIP), WI-MAX, email protocols (for example, internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (for example, extensible messaging and presence protocol (XMPP), session initiation protocol for instant messaging and presence leveraging extensions (SIMPLE) and/or instant messaging and presence service (IMPS)), short message service (SMS), or any other suitable communication protocol, including those still under development from submission date of this document.
Therefore, w % ben the frequency reaches a certain specificity, the dog bark detection device will stop the pet from barking. However, the dog bark detection device of this invention application is not necessarily aimed at barking, such as excitement, running, etc., can trigger the bark stopping function, as long as the vibration frequency reaches the preset frequency range can trigger the device bark stopping mechanism. In this embodiment, the way to stop barking is by electric shock. In some embodiments, the way to stop barking can be to make a beep sound, or to generate vibration and other ways.
In summary, the dog bark stopping device of this invention application can shield external noise interference, thereby improving the accuracy of the dog bark detection device monitoring. The dog bark detection device has the advantages of accurate judgment, strong anti-interference ability and high reliability. It can effectively prevent erroneous electric shock bark stopping situations.
In some embodiments, the applicable object of this invention's dog bark detection device is not limited to animal dogs. Animals other than dogs can also be used, such as cats, rabbits, chickens, or ducks, or geese and other animals. As long as they can make a sound, they can be suppressed by this invention's dog bark detection device.
