1 is a block diagram illustrating a scream detection unit according to an embodiment of the present invention.

The screaming detection unit may be installed in an elevator typically, or may be installed in various indoor spaces such as an underground parking lot, a changing room, and a toilet. In this specification, it is assumed that the screaming sensing unit 100 is installed in the elevator for convenience of explanation.

Referring to FIG. 1, a screaming sensing unit 100 according to an exemplary embodiment of the present invention includes a speech input unit 110, a control unit 120, and a warning output unit 130. Hereinafter, the function of each component will be described in detail. The voice input unit 110 receives voice of a user located inside the elevator. For example, the voice input unit 110 may be a microphone.

The control unit 120 analyzes the input user's voice to determine whether the user's voice is screaming or not.

According to an embodiment of the present invention, the controller 120 may determine that the user's voice is screaming when the user's voice is input for more than a predetermined time in decibels higher than a predetermined threshold decibel.

As an example, the controller 120 may determine that the user's voice is screaming when inputting a decibel level higher than 105 decibels, which is a critical decibel, for one second or more.

Further, according to an embodiment of the present invention, the voice of the user judged to be screaming may include "Ahak," " That is, the control unit 120 can determine all the screaming sounds. In particular, if the user's voice is "Ahak," When input is performed at a decibel level higher than the critical decibel level, the control unit 120 can recognize that the voice is a scream at a high recognition rate. However, the voice to be sensed in the present invention is not limited thereto, and various sounds can be sensed according to the place and the use.

The elevator may be an elevator provided inside the apartment. In this case, the controller 120 stores the voice of the residents of the apartment, compares the voice of the inputted user with the voice of the residents, analyzes the inputted voice of the user when the user is included in the tenants, It is possible to judge whether the voice is screaming or not. That is, it can be determined whether the voice of the user is screaming if any one of the tenants' voices is the same. Accordingly, it is possible to detect a screaming sound with a higher recognition rate.

Meanwhile, the controller 120 of the present invention is composed of a speaker-based HM-NET-based algorithm and a strong rejection algorithm for sounds other than a scream, among speech recognition techniques. In order to improve the reliability, it is possible to guarantee stable scream recognition at all times without being influenced by external factors such as communication failure by incorporating three ASIIC chips for speech recognition.

The warning output unit 130 outputs a warning sound and outputs a warning light when it is determined that the user's voice is screaming.

In more detail, the warning output unit 130 may include a sound output unit 131 for outputting a warning sound of sirens and sounds, and a lighting lamp 132 for blinking a warning light. As an example, the sound output unit 131 may be a speaker, and the illumination lamp 132 may be an LED illumination light.

On the other hand, an emergency interphone for voice communication with a surveillance camera (for example, CCTV) and a management room is installed inside the elevator. Meanwhile, although not shown in FIG. 1, the scream detector 100 may further include an internal camera. This may be for applying the scream detector 100 to an elevator without a surveillance camera. The scream detector 100 may further include various sensors.

The management room is provided with a communication device connected to the emergency interphone and a video output device for displaying a video shot by the surveillance camera or the internal camera. In this case, the communication device may be an interphone using a wired line installed in a management room, or may be an interphone using wireless such as WIFI, Zigbee, Z-wave, 3G, 4G, 5G, LTE, May be a mobile phone of an administrator of the management room, which may be registered in advance.

In this case, the scream detector 100 may further include a connection connector 140 connected to the control unit 120 and connected to the emergency interphone located in the elevator. Accordingly, when it is determined that the voice of the user is screaming, the control unit 120 can operate the emergency interphone, output a warning sound to the communication device of the management room through the emergency interphone, or transmit the sound inside the elevator.

Accordingly, even if the manager of the management room can not check the image displayed on the video output device, the status of the elevator is temporarily checked through the communication device of the management room, and then the image displayed on the video output device is checked to see if an emergency occurs Can be confirmed.

Hereinafter, a method for preventing a crime using a scream detector according to an embodiment of the present invention will be described with reference to FIG.

First, in step 202, the scream detector 100 is in an input standby state. In step 204, noise is input to the scream detector 100. In step 206, the scream detector 100 detects a noise Judge whether it is screaming or not.

If the input noise is not screaming, the process returns to step 202. Conversely, if the input noise is screaming, then in step 208 the scream detector 100 outputs a warning tone and a warning indicator. At this time, the warning sound and warning light are outputted for a predetermined time (for example, 35 seconds).

At the same time, in step 210, the scream detector 100 operates the emergency interphone.

Thereafter, in step 212, the manager of the management room confirms the situation in the elevator through the communication device, for example, the interphone. Then, in step 214, the manager confirms the image displayed on the video output device.

Subsequently, at step 216, the manager determines whether an emergency situation has occurred, based on the information identified at step 212 and step 214. If an emergency condition has not occurred (e.g., a child's crying, swarming noise, and loud noise, etc.), then the situation ends in step 218. Conversely, if an emergency situation has occurred, at step 220, the criminal can be alerted through the emergency interphone, the expense can be dispatched, or the call can be made to the safety report center 119.

Although not shown in FIGS. 1 and 2, the emergency detector 100 may include a short-range communication module, and a terminal device carried by the user may also include a short-range communication module. For example, the short range communication module may be an NFC module.

In this case, if it is determined that the user's voice is screaming, the control unit 120 transmits the call connection message to the user terminal device through the local communication module, and when the user terminal device receives the call connection message, It is possible to transmit a text message to the counterpart terminal device having a telephone number (for example, a terminal device of an administrator or a terminal device of a parent), or may attempt telephone conversation. This can further protect the safety of the user.

Hereinafter, the configuration of the scream detector 100 according to an embodiment of the present invention will be described in more detail with reference to FIGS.

FIG. 3 is a view showing a specific structure of the scream detector 100 according to an embodiment of the present invention, and FIG. 4 is a diagram illustrating a screaming unit attached to an elevator according to an embodiment of the present invention.

3 and 4, the scream detector 100 according to an embodiment of the present invention is attached to the elevator through the bracket 310. As shown in FIG.

More specifically, FIG. 3 (a) is a view showing a first surface of the scream detector 100. FIG. 3 (a), a microphone 110, which is a voice input unit, a speaker 131, which is a sound output unit, and an LED lighting lamp 132, which is an illumination lamp, may be installed on the first surface of the scream detector 100 .

As shown in Fig. 3B, a connection connector 140 for connection with an emergency interphone, a power connection unit 150 to which power is connected, a disconnection detection switch 160, and a disconnection detection switch 160 are connected to the second surface of the scream detector 100. [ . At this time, the detection operation is performed when the disassembly detection switch 160 is set to the left side, and the detection operation is not performed when the disassembly detection switch 160 is set to the right side.

At this time, in a state where the dismantling detection switch 160 is set to the left to perform the sensing operation, when the attached screaming sensor 100 is detached from the elevator, the emergency call can be transmitted to the management room through the emergency interphone.

That is, there may occur a case where the criminal discovers the emergency detector 100 by knowing that the emergency detector 100 is installed. In this case, the emergency detector 100 may not be able to perform the emergency call. Therefore, the controller 120 of the present invention can automatically perform the emergency call when the emergency detector 100 is disconnected from the bracket 310 after selecting the sensing function.

That is, in the conventional case, the emergency elevator is provided with an emergency interphone so that an internal passenger (user) can call the manager of the elevator in case the normal operation can not be performed due to a power failure, an equipment age, There is a problem in that it can not respond quickly to various emergency situations. In particular, although the CCTV installed in the elevator is helpful for the after-treatment, the passenger may not be able to press the emergency interphone due to the force of the criminal, etc. In such a case, the manager has a limitation in preventing the crime exist.

Accordingly, the scream detector 100 of the present invention recognizes the screaming sound and automatically calls the emergency interphone when the child or the woman feels danger in the elevator or the body can not be depressed due to a physical or sexual intruder At the same time, it is possible to inform the guards through the powerful warning light and the siren, to induce the immediate escape of the criminal, to protect the victim safely, and to suppress the attempt of the crime in the elevator.
