Recently, the number of households raising pets is increasing due to the influence of nuclear families and the increase in single-person households, and companion animals are recognized as members of the family rather than just companion animals, spending a lot of time and money to support them. Accordingly, the market for companion animals such as hospitals, beauty salons, hotels, and pet supply stores is expanding, and there is a report that the size of the companion animal market will reach 6 trillion won by 2020.

Not only is the number of households raising companion animals increasing, but the types of companion animals raised as companion animals are also diversifying, such as dogs, cats, hamsters, birds, fish, and reptiles. The largest number of households have dogs, where they can form a deep attachment relationship.

As companion animals are raised not only in private houses but also in shared houses such as apartments, in this case, care must be taken not to cause inconvenience to the surroundings due to the behavior of the pets.

In particular, it is true that the barking sound of a dog among companion animals is difficult to control unlike the owner's intention. The development of various devices to solve the problem became necessary.

Accordingly, in order to prevent the barking of companion animals, a band to be worn on the neck of the companion animal, and an anti-barking necklace having a sensor and an anti-barking means provided in the band have been developed. The technologies used here are based on the sound generated when the companion animal barks or the vibration of the neck surface. Barking was prevented by impacting the

As an example of such an anti-barking device for companion animals, Patent Document 1 includes a detection sensor and a high-voltage electric shock wave generating electrode, which automatically generates a shock wave when a vibration generated when a companion animal barks to stop the barking of the companion animal. A device is presented, but there is a problem in that the companion animal not only feels pain and is stressed by the shock wave applied at this time, but also ignores the shock wave and continues to bark when they get used to the shock wave. Not only that, this can lead to ethical issues of pet abuse, and it can also cause emotional stress to pet owners.

On the other hand, as another example of the companion animal barking prevention device, Patent Document 2 includes a noise detection sensor for detecting the barking of a pet dog, and a presser for controlling the movement of the lower jaw by pressing the lower jaw of the pet dog when the barking of the pet dog is detected. Although a preventive device is proposed, it is difficult to detect the barking of a pet dog through the noise sensor in a noisy place, and even if the pusher works, the movement of the lower jaw cannot be completely blocked. there is a problem.

Therefore, it is necessary to develop a system that can more accurately detect the barking of companion animals, do not apply any pain, and effectively prevent the barking of companion animals.

The present invention will be described in detail with reference to embodiments and drawings of the present invention. It will be apparent to those of ordinary skill in the art that these examples are only presented by way of example to explain the present invention in more detail, and that the scope of the present invention is not limited by these examples. .

In order to clearly explain the invention proposed in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification. In addition, "unit" described in the specification means one unit or block that performs a specific function.

Hereinafter, an embodiment of the present invention will be described. However, the scope of the present invention is not limited to the following preferred embodiments, and those skilled in the art can implement various modified forms of the contents described herein within the scope of the present invention.

The present invention relates to a system for predicting a companion animal's barking in advance and operating an anti-barking means before the companion animal barks to prevent or control the companion animal from barking loudly.

More specifically, after collecting the EMG signal data of the companion animal for a predetermined period and analyzing it to secure the EMG signal data before the companion animal barks, the EMG signal before barking is continuously monitored in daily life. When a signal is observed, it relates to a system for preventing and preventing the barking of a companion animal in advance by applying electrical stimulation to the vocal cord muscles of the companion animal to contract the vocal cord muscles.

The companion animal anti-barking system of the present invention collects and monitors the EMG signal data of the companion animal through the anti-barking collar 1 worn on the neck of the companion animal, and can apply electrical stimulation to the companion animal according to the monitoring result. .

1 and 2 are schematic views of the anti-barking necklace 1, and referring to FIGS. 1 and 2, the anti-barking necklace 1 includes a necklace 10 worn on the neck of a companion animal; A plurality of EMG sensors 20 provided on the inside of the necklace along the length direction of the necklace (10); at least one pair of electrodes 30 provided inside the necklace 10; and a main body 40 installed on the necklace 10 .

The necklace 10 is worn to surround the neck of the companion animal, is formed in the form of a strap or a band, and is provided with fixing means 11 that can be detachably coupled to each other at both ends of the necklace 10 .

The fixing means 11 may be implemented in a structure such as a buckle, a hook of a snap-fit structure, or a Velcro.

For example, when the fixing means 11 is implemented in a buckle structure, a plurality of fastening holes 11a formed along the longitudinal direction of the necklace 10 at one end of the necklace 10 and the other end of the necklace 11 are disposed. The necklace 10 can be worn on the neck of the companion animal by being coupled in such a way that the pin of the buckle 11b is inserted into the fastening hole 11a, including the buckle 11b. In this case, the length of the anti-barking collar 1 worn on the companion animal can be adjusted by using the fastening holes 11a at different positions according to the thickness of the neck of the companion animal.

The electromyogram sensor 20 is provided in plurality along the longitudinal direction of the collar 10 on the inside of the collar, that is, in the direction in which the collar and the body of the companion animal are in contact, and measures the electromyogram signal of the muscle present in the neck of the companion animal. do. Preferably, each EMG sensor 20 is spaced apart from each other by a predetermined distance to surround the neck of the companion animal, so that the movement of the muscle that occurs when the companion animal barks can be more accurately measured. The signal measured by the EMG sensor 20 is transmitted to the controller 41 to be described later.

When it is determined that the companion animal is barking by the control unit 41 to be described later, the electrode 30 receives a signal from the control unit 41 and applies electrical stimulation to the companion animal's neck to prevent or weaken the companion animal's barking. For this purpose, it may be provided as a pair, or two or more pairs, including one electrode to which an anode (+) is applied and the other electrode to which a cathode (-) is applied.

The electrode 30 generates a low-frequency microcurrent and acts on the vocal cord muscles of the companion animal, thereby preventing the companion animal from barking or reducing the noise when barking. Such low-frequency microcurrents, such as NMES (Neuromuscular electrical stimulation) or EMS (Electrical muscle stimulation), act on a muscle or a muscle nerve to contract or relax a muscle without pain, and a low-frequency microcurrent having a frequency of 1000 Hz or less. can be

Preferably, it may have a frequency of 250 Hz or less, and more preferably, it has a frequency of 180 Hz or less, a current of 10 to 400 μA, and a voltage of 0.9 to 1.5 V. And, by using such a low-frequency microcurrent, it is possible to prevent barking or suppress noise caused by barking without abuse of companion animals, unlike the conventional electric shock method.

The electrode 30 may be formed to protrude into the necklace 10 . Also, when the companion animal wears the anti-barking collar 1, the electrode 30 may be disposed only in a predetermined region of the collar 10 so as to be located in a region close to the vocal cord muscles of the companion animal. ) is placed near the vocal cord muscles of the companion animal to prevent barking of the companion animal or suppress noise, but the energy consumed here is minimized, so the use time of the anti-barking collar 1 can be extended .

When a companion animal wears such a necklace, the necklace rotates on the companion animal's neck according to the movement of the companion animal. Since 30 is disposed, there is a problem in that the effect of preventing barking or suppressing noise is weak.

In order to prevent this, at least one ring 12 is formed on the outside of the necklace 10 in the longitudinal direction of the necklace 10, and the ring 12 and the companion animal are connected through a fixing means such as a string or tongs. Rotation of the necklace 10 can be prevented by connecting clothes or connecting a lead line for controlling the companion animal by holding one end of the person while walking on the ring 12 .

The main body 40 is provided on the necklace 10 , and includes a control unit 41 and a battery 42 inside.

The control unit 41 collects the EMG signal data of the companion animal approved by the EMG sensor 20, transmits it to the server, receives the EMG signal data just before the companion animal barks analyzed in the server, and thereafter the EMG of the companion animal When monitoring the signal in real time, when the EMG signal of the companion animal transmitted from the EMG sensor 20 is similar to the EMG signal immediately before the companion animal barks received from the server, an operation signal is applied to the electrode 30 to generate a low-frequency microcurrent control to occur.

The battery 42 is a power supply means for supplying power to the EMG sensor 20, the electrode 30, the control unit 41, etc., is provided in the main body 40, may be a replaceable or rechargeable battery, and is rechargeable. In the case of , it may be charged through a wired charging method or a wireless charging method using a USB terminal, etc., and may be charged through a complex charging method in which two or more charging methods are mixed.

Preferably, it can be charged through a non-contact wireless charging method. In this case, a wireless power receiving unit 61 is provided in the main body 40 to receive power in a non-contact manner from the wireless power transmitting unit 62 located outside to be charged. can In this case, it is possible to charge even without detaching the anti-barking necklace 1 .

The main body 40 may further include a sound sensor 50 for detecting a barking sound of a companion animal. When monitoring the companion animal's barking, if the EMG sensor 20 is not observed or an error occurs and the operation signal is not transmitted to the electrode 30 before the companion animal barks, the sound sensor 50 detects the companion animal's barking. By detecting a sound and applying an operation signal to the electrode 30 through the controller 41 , the barking of the companion animal may be stopped or the barking noise may be reduced.

In addition, the signal generated from the sound sensor 50 is transmitted to the server together with the signal generated from the EMG sensor 20 , and may be used to secure the EMG signal before the companion animal barks.

The companion animal barking prevention system of the present invention primarily measures the EMG signal of the companion animal using the above-described anti-barking collar 1, and based on this, secures the EMG signal before the companion animal barks, and then barks secondarily. The companion animal's EMG signal is monitored in real time through the prevention collar (1). This is a system that aims to prevent problems such as noise caused by barking of companion animals and disputes between neighbors in advance by preventing barking or reducing noise when companion animals bark.

The EMG signal before the companion animal barks may be obtained through the server.

More specifically, the server may include: a data collection step of receiving an EMG signal of the companion animal measured for a predetermined period through the anti-barking collar 1 worn on the neck of the companion animal; a data analysis step of extracting an EMG signal just before the companion animal barks by using the EMG signal obtained in the data collection step; and an analysis data transmission step of transmitting the EMG signal just before the companion animal barks, obtained in the data analysis step, to the control unit 41 of the anti-barking collar 1 .

The operation of this server is performed for a predetermined period before monitoring the barking of the companion animal in earnest. The predetermined period is a user-defined period, for example, may be performed for a period of about one week to one month, but may be performed shorter than one week or longer than one month as needed.

The data collection step is a step of measuring and collecting EMG signals according to the movement of the vocal cord muscles of the companion animal through the EMG sensor 20 mounted on the inside of the companion animal's anti-barking collar 1 . When the data collection step is performed in the server, the anti-barking collar 1 for companion animals measures the EMG signal measured through the EMG sensor 20, and a pre-EMG signal collection step of transmitting it to the server is performed.

In this step, the sound signal collected by the sound sensor 50 may also be optionally collected.

The data analysis step is a step of extracting the EMG signal just before the companion animal barks by analyzing the EMG signal data received from the server. In this case, the data used for analysis may be data obtained by quantifying EMG signal data using an analysis method such as integral average, RMS, peak-to-peak, and RMS-amplitude probability distribution.

In the data analysis step, when the peak of the EMG signal data is greater than or equal to a predetermined value, or when the user or manager determines that the companion animal is barking, the specified peak is determined as the peak when the companion animal barks, It judges and extracts the EMG signal just before the companion animal barks.

Alternatively, a big data-based deep learning technology that compares the input EMG signal just before the companion animal barks with the collected EMG signal data and extracts it when it is determined that the companion animal is the EMG signal just before barking may be applied. Due to the nature of deep learning technology, when the target EMG signal is accumulated, the accuracy of discriminating the EMG signal just before the companion animal barks is increased in various conditions and surrounding environments of the companion animal. can

If the sound signal collected from the sound sensor 50 is also used for data analysis, the EMG signal just before the companion animal barks can be obtained by analyzing the EMG signal data at the time when the companion animal is determined to bark through the sound signal. there is. In this way, when the sound sensor 50 is used together, it is possible to more accurately determine when the companion animal barks without requiring additional labor, so that more accurate processing data can be obtained.

The EMG signal just before the companion animal barks means the EMG signal before the time when the companion animal actually starts to bark or barks the loudest. It may be in the form of integrated data that allows a predetermined error based on the average value of the data for each case, for example, average amplitude, average frequency, average time, and the like.

The EMG signal just before the companion animal barks obtained through the data analysis step is transmitted from the server to the anti-barking collar 1 again through the analysis data transmission step.

Thereafter, the anti-barking collar 1 continuously measures the EMG signal of the companion animal through the EMG sensor 20 and transmits it to the control unit 41, and the same as the EMG signal immediately before the companion animal barks received from the server. When the EMG signal of the companion animal is measured, by applying an operation signal to the electrode 30, electrical stimulation is applied to the vocal cord muscles of the companion animal to contract the vocal cord muscles, thereby preventing the companion animal from barking in advance.

At this time, the electrode 30 applies electrical stimulation using a low-frequency microcurrent of a neuromuscular electrical stimulation (NMES) or electrical muscle stimulation (EMS) method. However, since it contracts the vocal cord muscles of the companion animal without causing any stimuli that the companion animal can perceive, the movement of the vocal cord muscles is disturbed to prevent the companion animal from barking or to reduce the noise when the companion animal barks.

In the present invention, by predicting and preventing the barking of the companion animal in advance through this method, it is possible to help the companion animal, the companion, and the neighbors to escape from noise pollution caused by the barking of the companion animal without abuse of the companion animal.

Also, the EMG signal measured in the monitoring step performed after securing the EMG signal just before the companion animal barks is transmitted to the server, and the EMG signal just before the companion animal barks is transmitted from the EMG signal transmitted to the server through the deep learning method. is extracted, and the extracted data is again accumulated as big data. Therefore, as monitoring continues, it is possible to more accurately determine the status of the companion animal just before barking, thereby preventing the companion animal from barking.

The companion animal barking prevention system includes a user terminal capable of communicating with the server and the companion animal barking prevention collar, and checks the operating status of the server and the barking prevention collar 1 through the user terminal, or is stored in the server or in real time. You can check the EMG signal of your companion animal, which is measured by
