Description

{SYSTEM FOR WARNING FLOOR NOISE}

The present invention relates to an inter-story noise notification system, and more particularly, to an inter-story noise notification system that allows a lower-floor occupant to directly experience the inter-floor noise experienced by upper-floor occupants,

Apartment houses such as apartments have multiple floors of residential space. And each residential space of the apartment house is partitioned by slabs, which form the floor for the upper story residential space and ceiling for the lower story residential space.

In this way, since one slab forms the ceiling of the upper floor residential space and the lower floor residential space, the noise of the upper floor residential space is transmitted to the lower floor residential space through the slab. For example, footsteps of upper-floor residents, dropping of objects in upper-level residential spaces, and attraction of objects in upper-floor residential spaces cause the vibration of the slab, and the vibration of the slab causes noise in the lower-floor residential space.

Residents of multi - family homes are frequently arguing due to the interstate noise, which is the phenomenon that the noise of the upstairs residential space is transmitted to the downstairs residential space. And in some cases, it does not stop at a mere argument, but also leads to melee and murder. Therefore, interlayer noise is recognized as one of the serious social problems today.

What is now known as a way to prevent disputes between residents due to interstory noise is to give the slab the ability to absorb noise and vibration. However, this method is not effective because it can only be applied to newly built apartment buildings and can not be applied to already built apartment houses.

Another currently known measure to prevent disputes between residents due to interstory noise is to warn residents who have caused interstory noise. The idea is to draw attention to upper-floor residents by informing upper-floor residents that lower-floor residents may experience pain due to interstate noise. Korean Patent Publication No. 2009-0081560, Korean Patent No. 1069754 and Korean Patent No. 1268318 disclose such a method.

The present invention seeks to provide an inter-floor noise notification system that can remind upper-floor residents of floor-to-floor noise experienced by lower-floor occupants,

One embodiment of the present invention relates to a vibration sensor for detecting vibrations of a ceiling mounted on a ceiling of a lower layer of a building and connected to a communication network and outputting a vibration signal as an electrical signal of the ceiling; A voice output unit installed on an upper floor of the common house so as to be connected to the communication network and outputting an electrical signal by voice; And a control unit coupled to the communication network, for receiving the vibration signal output from the vibration sensor, storing a reference excess vibration signal, which is a vibration signal having a level greater than a preset reference level, in the database, And a web server for transmitting the interlayer noise notification message to the web server.

In another embodiment of the present invention, a ceiling is installed on a ceiling of a lower layer of a common house so as to be connected to a communication network to detect the vibration of the ceiling, compare the level of the vibration signal as an electrical signal thereof with a predetermined reference level, A vibration sensor for outputting a reference excess vibration signal which is a vibration signal of a level; A voice output unit installed on an upper floor of the common house so as to be connected to the communication network and outputting an electrical signal by voice; And a web server connected to the communication network and storing the reference excess vibration signal output from the vibration sensor in a database and transmitting the reference excess vibration signal to the voice output device. At this time, the vibration sensor includes a lamp and is configured to operate the lamp in a different color depending on whether the vibration signal is the reference excess vibration signal.

The interlayer noise notification system includes a lower layer router installed in a lower layer of the common house to be connected to the communication network and the vibration detection and transmitting a signal output from the vibration detector to the web server; And a upper layer sharer installed in the upper layer of the common house to be connected to the communication network and the voice output unit and transmitting the reference excess vibration signal transmitted from the web server to the voice output unit.

Also, the interlayer noise notification system includes a noise detector installed on the upper floor of the apartment so as to be connected to the communication network, for sensing the noise of the residential space and outputting a noise signal as an electrical signal of the noise. At this time, the web server transmits the reference excess vibration signal stored in the database to the voice output device when the noise signal is at a level lower than a predetermined reference level. The web server also transmits the reference excess vibration signal to the voice output device when storing the reference excess vibration signal in the database.

Alternatively, the web server may transmit the reference over-vibration signal to the audio output device at the time of storing the reference over-vibration signal in the database and at a preset time.

The audio output device is provided with a lamp and is provided to operate the lamp when outputting the reference excess vibration signal by voice. The web server stores the time of receiving the reference excess vibration signal and the time of transmission in the database.

The present invention can be applied to apartment houses without the need of processing wall concrete and slab concrete of already built apartment buildings because the existing network is used.

In addition, since the present invention uses a router for assigning a private IP address to a vibration sensor, a voice output device, and a noise detector, it is possible to operate using only one Internet line.

According to the present invention, a resident of a lower layer can visually confirm whether or not the current interlayer noise exceeds the statutory standard, and whether it is currently being reproduced or is going to be upstaged.

Further, according to the present invention, since the residents of the upper floor of the apartment house directly experience the interlayer noise caused by themselves in a quiet environment, the attention of the upper floor resident can be very effectively evoked.

In addition, according to the present invention, since the residents of the upper floors of the apartment block experience the floor noise caused by themselves, the floor noise of the upper floor residents can be immediately stopped.

According to the present invention, since the voice output device flashes the lamp when the interlayer noise generated by the upper floor resident is output to the upper floor residential space, the upper floor resident can easily grasp that the interlayer noise experienced by her / .

Also, according to the present invention, since the inter-floor noise caused by the upper-floor occupant and the time of the inter-floor noise are stored in the database, it can be used as evidence in the case of a dispute between the residents regarding the inter-floor noise.

Hereinafter, preferred embodiments of the interlayer noise notification system according to the present invention will be described in detail with reference to the drawings. It is to be understood that the terminology or words used herein are not to be construed in an ordinary sense or a dictionary, and that the inventor can properly define the concept of a term to describe its invention in the best possible way And should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention.

≪ Embodiment 1 >

1 and 2, the interlayer noise notification system 100 according to the first embodiment of the present invention includes a vibration sensor 110, a router 120, a voice output unit 130, a web server 140, and a database 150. [

The vibration sensor 110 is installed on the ceiling of the lower housing 10 to sense the vibration of the ceiling of the lower housing 10. Here, the lower layer 10 of the apartment house is a relative concept. For example, one layer forms a lower layer 10 with respect to two layers, and the two layers form a lower layer 10 with respect to three layers. Therefore, if the apartment house is composed of 10 layers, the vibration sensor 110 is installed on the ceiling of the first to ninth layers. In addition, the vibration sensor 110 outputs a vibration signal. Here, the vibration signal is an electrical signal containing information on the waveform of the vibration of the ceiling of the lower layer 10.

The audio output device 130 is installed in the upper floor 20 of the apartment house to reproduce and output an electrical signal by voice. Here, the upper story 20 is also a relative concept as the lower story 10 of the lower house. For example, the two layers constitute the upper layer 20 with respect to one layer, and the three layers constitute the upper layer 20 with respect to the two layers. Therefore, if the apartment house is composed of 10 layers, the voice output device 130 is installed on the 2nd to 10th floors. 2, the voice output device 130 is installed on the ceiling of the upper layer 20, but may be otherwise provided on the wall of the upper layer 20 or other locations.

The router 120 is installed in both the lower layer 10 and the upper layer 20 of the apartment house and is connected to the communication network through an Internet line (not shown) coming into the lower layer 10 and the upper layer 20, .

The sharer 120 of the lower layer 10 is also connected to the vibration sensor 110 of the lower layer 10 by assigning a private IP to the vibration sensor 110 of the lower layer 10, And receives a vibration signal from the vibration sensor 110. [ The router 120 of the upper layer 20 is connected to the voice output unit 130 of the upper layer 20 by assigning a private IP to the voice output unit 130 of the upper layer 20, And transmits the electrical signal to the audio output device 130. [

As the router 120, either a wired or wireless router may be used. However, it is preferable that a wireless router that does not require wiring for connection between the router 120 and the vibration detector 110 or the audio output device 130 is used as the router 120. [

The web server 140 is connected to a communication network. The web server 140 receives the vibration signal sensed by the vibration sensor 110 from the router 120 of the lower layer 10 and compares the level of the received vibration signal with a preset reference level. Here, the reference level means a vibration level that causes a noise upper limit between statutory permissible levels (according to the "Regulations on Housing Construction Standard, etc." as of 2012), a light impact sound has an upper limit of 58 decibels and a heavy impact sound has an upper limit of 50 decibels.

If the comparison result indicates that the vibration signal received from the lower layer router 120 is a reference excess vibration signal having a level exceeding the reference level, the web server 140 stores the reference vibration excess signal in the database 150. At this time, the web server 140 also stores the time of receiving the reference excess vibration signal from the lower layer router 120 in the database 150.

The web server 140 storing the reference excess vibration signal in the database 150 transmits the reference excess vibration signal to the router 120 of the upper layer 20. Then, the router of the upper layer 20 transmits the received reference over-vibration signal to the voice output unit 130, and the voice output unit 130 reproduces and outputs the received reference over-vibration signal by voice. When the reference over-vibration signal is reproduced and output by voice, the resident of the upper layer 20 experiences the interlayer noise caused by her / himself, so that he / she is careful not to cause inter-floor noise in the future. The web server 140 stores the time when the reference excess vibration signal is transmitted to the router 120 of the upper layer 20 in the database 150.

A resident of the upper layer 20 may mistaken the interlayer noise output from the voice output device 130 as being caused by her upper floor occupant. Accordingly, the audio output device 130 is provided with a lamp (not shown) and is provided to operate (turn on or blink) the lamp when outputting a reference excess vibration signal. In this case, the resident of the upper layer 20 can see the lamp of the voice output device 130 and can distinguish whether the interlayer noise currently experienced by the upper layer 20 is outputted from the voice output device 130 or is caused by the upper floor resident thereof .

Also, the resident of the upper layer 20 can protest to the web server 140 operating agency that the noise generated from the audio output unit 130 has not been caused. In this case, the operator may present the reference over-vibration signal stored in the database 150 and the time of occurrence of the over-vibration signal as evidence. In this case, however, the resident of the upper layer 20 may consider the reliability of the presented evidence. Therefore, it is preferable that the web server 140 is operated by a public authority such as a country or a local government, or a certification body that has been certified by the agency.

On the other hand, the occupant of the upper floor 20 can further sympathize with the suffering of the occupant of the lower floor 10 when he / she is heard in a quiet environment than when he / she heard the floor noise generated in the noisy environment. Therefore, the output from the audio output device 130 needs to be made when the upper layer 20 is placed in a quiet environment. To meet this need, the interlayer noise notification system 100 may further include a noise detector 160 do.

The noise detector 160 is installed in the upper floor 20 of the apartment house to detect the noise of the living space. Since the upper floor 20 of the apartment house is a relative concept as described above, if the apartment house is composed of 10 floors, the noise detector 160 is installed on the 2nd to 10th floors. According to FIG. 2, the noise detector 160 is installed on the ceiling of the upper layer 20, but may alternatively be installed on the wall of the upper layer 20 or other locations.

The noise detector 160 is also assigned a private IP address from the router 120 of the upper layer 20 and transmits the noise signal to the router 120 of the upper layer 20. The noise signal is an electrical signal that contains information on the waveform of the noise in the residential space of the upper layer 20.

When the noise sensor 160 is installed, the web server 140 receives the noise signal from the router 120 of the upper layer 20, and the level (unit: decibels) of the received noise signal and the predetermined reference level Decibels).

If it is determined that the noise signal is lower than the reference level, that is, if the upper floor 20 is judged to be quiet, the web server 140 transmits the reference excess vibration signal stored in the database 150 to the upper layer 20, To the router (120). At this time, the web server 140 stores the reference over-vibration signal in the database 150 for the first time only when the noise signal is lower than the reference level, 120, since once regenerated interlayer noise is reproduced thereafter, adverse effects that may lead to complaints or protests beyond the ventilation of the attention of the residents of the upper layer 20 may occur.

In order to enable a resident of the upper layer 20 to listen to his / her interlayer noise in a quiet environment, the web server 140 transmits the reference excess vibration signal stored in the database 150 to the router 20 of the upper layer 20 (120). For example, the web server 140 is recognized as a relatively quiet time and can transmit all the reference exceeded vibration signals stored in the database 150 to the router 120 of the upper layer 20 at that predetermined 11 pm. In this case, the installation of the noise detector 160 may be omitted.

The time when the web server 140 transmits the reference excess vibration signal to the router 120 of the upper layer 20 may be selected differently. For example, the web server 140 may transmit the reference excess vibration signal to the router 120 of the upper layer 20 immediately when it determines that the vibration signal received from the router 120 of the upper layer 20 is the reference excessive vibration signal have. In this case, the installation of the noise detector 160 is unnecessary, and the resident of the upper layer 20 can immediately stop the current interlayer noise caused by her.

In another example, when the web server 140 determines that the vibration signal received from the router 120 of the upper layer 20 is the reference excessive vibration signal, the web server 140 directly transmits the reference excess vibration signal to the router 120 of the upper layer 20 And then transmit the reference excess vibration signal back to the router 120 of the upper layer 20 when the upper layer 20 is in a quiet environment.

Hereinafter, the operation of the interlayer noise notification system 100 will be described with reference to FIG. 3 shows a case where the web server 140 determines whether the upper layer 20 is in a quiet environment by using the signal of the noise detector 160 and transmits the reference excess vibration signal to the router 120 of the upper layer 20 The timing at which the web server 140 transmits the reference excess vibration signal to the router 120 of the upper layer 20 can be variously selected as described above.

The vibration sensor 110 of the lower housing 10 senses the vibration of the ceiling of the lower layer 10 and transmits it to the router 120 of the lower layer 10 and the noise detector 160 of the upper housing 20, Detects the noise of the residential space of the upper layer 20 and transmits it to the router 120 of the upper layer 20. The router 120 of the lower layer 10 transmits the vibration signal to the web server 140 and the router 120 of the upper layer 20 transmits the noise signal to the web server 140. [

The web server 140 compares the level of the received vibration signal with a preset reference level to determine whether the vibration signal is a reference excess vibration signal, . Thereafter, the web server 140 compares the level of the received noise signal with a preset reference level to determine whether the upper floor (20) housing space is quiet. Then, the web server (140) 20 to the router 120 of the base station. At this time, the web server 140 stores the time when the reference excess vibration signal is transmitted to the router 120 of the upper layer 20 in the database 150.

Then, the router 120 of the upper layer 20 transmits the received reference excess vibration signal to the voice output device 130, and the voice output device 130 reproduces the received reference vibration excess signal by voice, And outputs it to the main space of FIG.

The vibration detector 110, the voice output device 130 and the noise detector 160 communicate with the web server 140 via the router 120. [ Alternatively, the communication between the vibration sensor 110, the voice output device 130 and the noise sensor 160 and the web server 140 may be performed without the router 120. In this case, the vibration sensor 110, the voice output device 130, and the noise sensor 160 may be directly connected to the communication network by wire or wireless, and each will have a public IP address.

≪ Embodiment 2 >

The controller compares the sensed vibration signal with a preset reference level to determine if the vibration signal is a reference excess vibration signal and if so, allows the reference excess vibration signal to be transmitted to the router 120 of the lower layer 10 .

The vibration sensor 110 also includes a lamp. The control unit operates the lamp in a different color depending on whether the vibration signal is a reference excess vibration signal. For example, the control unit operates the lamp in green if the vibration signal is not the reference excess vibration signal, and operates the lamp in red if the vibration reference signal is the reference excessive vibration signal. In such a case, the occupant of the lower layer 10 can visually confirm whether the current interlayer noise exceeds the statutory standard and whether it is currently being reproduced or is going to be in the upper layer 20.

The web server 140 of the present embodiment stores the reference excess vibration signal transmitted by the router 120 of the lower layer 10 and its reception time unlike the first embodiment and the router 120 of the lower layer 10 The transmitted vibration signal is not compared with a preset reference level.

Hereinafter, the operation of the interlayer noise notification system 100 will be described with reference to FIG. 4 shows a case where the web server 140 determines whether the upper layer 20 is in a quiet environment by using the signal of the noise detector 160 and transmits the reference excess vibration signal to the router 120 of the upper layer 20 The time when the web server 140 transmits the reference excess vibration signal to the router 120 of the upper layer 20 can be variously selected as described in the first embodiment.

The vibration sensor 110 of the lower housing 10 detects the vibration of the ceiling of the lower layer 10 and then compares the level of the vibration signal with a preset reference level to determine whether the vibration signal is a reference excess vibration signal . When the vibration signal is determined to be the reference excess vibration signal, the vibration sensor 110 operates the lamp (not shown) in red and transmits the reference excess vibration signal to the router 120 of the lower layer 10. Then, the router 120 of the lower layer 120 transmits the received reference excess vibration signal to the web server 140. On the other hand, if it is determined that the vibration signal is not the reference excess vibration signal, the lamp is turned to green.

Meanwhile, the noise detector 160 of the upper floor 20 of the apartment house senses the noise of the upper floor 20 's residential space and transmits it to the router 120 of the upper floor 20. The router 120 of the upper layer 20 transmits the received noise signal to the web server 140.

The Web server 140 stores in the database 150 the reference excess vibration signal transmitted from the router 120 of the lower layer 10 and the reception time thereof. The web server 140 compares the level of the noise signal received from the router 120 of the upper layer 20 with a preset reference level to determine whether the upper floor 20 residential space is quiet, To the router (120) of the upper layer (20). At this time, the web server 140 stores the time when the reference excess vibration signal is transmitted to the router 120 of the upper layer 20 in the database 150.
