In an embodiment, the interlayer noise and vibration detection device 100 may include a detection unit 110, a memory unit 120, a determination unit 130, and an alarm unit 140, as shown in FIG. 2. .

The sensing unit 110 is installed on the ceiling of each household and detects a generated noise and vibration value.

In an embodiment, the sensing unit 110 may include at least one of an acceleration sensor, a vibration sensor, and a microphone.

The acceleration sensor and the vibration sensor are installed on the ceiling in the household and receive direct shock vibration generated by running or walking motions, and convert them into electrical signals and transmit them to the determination unit 130. The transmitted vibration value can be measured.

The microphone is installed on the ceiling in the household, receives air transmission noise generated by high-power, sound equipment, etc., converts it into an electric signal, and transmits it to the determination unit 130, and thus the noise value transmitted from the upper floor to the lower floor. Can be measured.

In one embodiment, the sensing unit 110 is described as being installed on a ceiling within a household, but may be installed on a wall between the household and the household in some cases.

The memory unit 120 presets and stores a reference value allowed for determining inter-floor noise.

Here, the reference value may be a legal standard for inter-floor noise according to the type of inter-floor noise, and for example, direct shock vibration may be set to 57 db during the day, 52 db at night, and in the case of air transmission noise, 45 db during the day and 40 db at night.

In an embodiment, the memory unit 120 may store properties of a noise source according to a sound and intensity of a frequency.

In an embodiment, the memory unit 120 may set and store sensitivity felt by the user for each attribute of the noise source. For example, if the property of the noise source is beating sound, the sensitivity can be set to 7, and when the property of the noise source is the sound of turning off the chair, the sensitivity can be set to 5 and stored.

The determination unit 130 receives a noise vibration value from the detection unit 110, compares the received noise vibration value with a reference value stored in the memory unit 120, and when the noise vibration value is greater than or equal to the reference value, the noise vibration value Is transmitted to the server 200 in real time.

That is, the noise vibration value detected by the detection unit 110 is not directly transmitted to the server 200, and the noise vibration value is transmitted to the server 200 only when it is greater than or equal to a preset reference value, thereby reducing the system load of the server. have.

In one embodiment, the determination unit 130, when the noise vibration value received from the detection unit 110 is greater than or equal to the reference value, the noise vibration value is changed to a frequency signal through a fast Fourier transform, and then the frequency The analysis may be performed to analyze the properties of the noise source, and at this time, the properties of the analyzed noise source may be transmitted to the server 200.

In other words, it is possible to grasp the generation factor and type that caused the noise vibration by analyzing the vibration or the sound of which intensity and frequency the sound is composed of.

In an embodiment, the determination unit 130 may read the sensitivity stored in the memory unit 120 according to the properties of the noise source analyzed through frequency analysis. At this time, the read sensitivity may be transmitted to the server 200.

The alarm unit 140 is installed on a wall in the household, receives a notification signal from the server 200, and informs the user that noise or vibration exceeding a reference value has occurred.

In an embodiment, the alarm unit may include at least one of a display, a light emitting lamp, and a speaker.

For example, a warning character may be output through a display or light may be output through a light-emitting lamp to visually notify that inter-floor noise vibration has occurred, and a warning sound or warning character may be output through a speaker to notify audibly. .

In one embodiment, the alarm unit 140 may be integrally configured with an interphone provided in each household.

The server 200 is communicatively connected with the inter-floor noise and vibration detection device 100, and stores information about each household (eg, member name, contact information, balance, interphone identification number, etc.) by number and In addition, the noise vibration value is received from the inter-floor noise vibration detection device 100, and a notification signal for notifying the generation of the noise vibration value is generated.

In one embodiment, the server 200 may be installed in a management office or the like and receive a noise vibration value from the inter-floor noise vibration detection device 100 installed in each household.

In one embodiment, when receiving a noise vibration value exceeding a preset reference value from the determination unit 130 of the inter-floor noise vibration detection device 100, the server 200 generates a notification signal to generate a corresponding noise vibration value. It may be transmitted to the alarm unit 140 of the upper-level household inter-floor noise and vibration detection device 100. However, if necessary, the notification signal can be transmitted to the avoiding household (lower households).

In one embodiment, the server 200 may store and manage the noise and vibration values received from the inter-floor noise and vibration detection device 100 in a database (not shown) for each generation to monitor the inter-floor noise and vibration state, and the database ( (Not shown) can be distinguished between the households that caused the floor noise and vibration based on the information on the households in the city.

In an embodiment, the server 200 may store date and time information on which a noise vibration value exceeding a preset reference value is measured and convert it into a database.

In an embodiment, the server 200 may store information on which properties of the noise source are analyzed through frequency analysis and a sensitivity according to the properties of the noise source and convert it into a database.

In one embodiment, the server 200 may notify the fact of damage to the floor noise and vibration by transmitting a warning text, a warning sound, etc. to the household generating the floor noise vibration value.

In one embodiment, the server 200, when two or more vibration noise values are received from two or more inter-floor noise vibration sensing devices 100 among the plurality of inter-floor noise vibration sensing devices 100, the received plurality of The magnitudes of the vibration noise values are compared with each other, and the upper-level generation transmitting the largest vibration noise value is determined as the inter-floor noise generation generation, and the inter-floor noise vibration detection device 100 of the generation determined as the inter-floor noise generation generation. An alarm signal may be transmitted to the alarm unit 140. In other words, since excessive noise and vibration values are sometimes transmitted to households with two or three floors apart, it is possible to accurately determine and inform the generation of inter-floor noise to prevent misunderstandings.

For example, when noise and vibration values of 60db, 70db, and 62db are received from the three inter-floor noise and vibration detection devices 100, the size values of these are compared and the upper-level households in which the largest size of 70db is detected is inter-floored. It may be determined as the generation generating noise, and a notification signal may be transmitted to the alarm unit 140 of the generation determined as the generation generating interfloor noise.

In one embodiment, the server 200, when two or more vibration noise values are received from two or more inter-floor noise vibration sensing devices 100 among the plurality of inter-floor noise vibration detection devices 100, the received plurality of vibration noise The magnitudes of the values are compared with each other, and when the magnitudes are the same, the sensitivity for each attribute of the noise source is compared, and the higher sensitivity can be determined as the generation of inter-floor noise generation.

For example, it receives a noise vibration value of 70db determined as the property of the beating sound from the interfloor noise vibration detection device 100 of Room 501, and at the same time, it is determined as the property of the chair pulling sound from the interfloor noise vibration detection device 100 of Room 502. In the case of receiving the noise vibration value of 70db, the magnitude of the noise vibration value is the same, so comparing the sensitivity of each property of the noise source, the upper-level household of the 501 has the property of the beating sound corresponding to the higher sensitivity. May be determined as the generation of inter-floor noise generation, and a notification signal may be transmitted to the alarm unit 140 of the household determined as the generation of inter-floor noise generation.

For this reason, when two or more vibration noise values of the same size are received at the same time, by notifying the generation corresponding to the most sensitive noise source, it is possible to effectively suppress the occurrence of noise vibration with high sensitivity to the user's noise. There is an effect of reducing errors that may occur only by comparing the magnitude of the noise and vibration values.

In one embodiment, when the vibration noise value is received from all of the plurality of inter-floor vibration noise detection devices 100, the server 200 may consider it as external noise and determine that an error has occurred, and if it is determined that an error has occurred , An error generation signal may be generated and transmitted to the alarm unit 140 of the interlayer vibration noise detection device 100. As a result, it is possible to solve the problem of generational disputes due to misunderstanding of external noise as inter-floor noise vibration.

When an error occurs, it is output as an alarm signal, a different warning sound, and a warning text so that users can distinguish it. For example,'Excessive external noise is being generated. You can provide information about the occurrence of an error, such as'Please close the window.'

In one embodiment, the server 200 may be linked with a portable terminal such as a smartphone, and when a noise vibration value greater than a reference value is generated, the server 200 may notify the portable terminal of the generation generating the corresponding noise vibration value through a text message.

The interfloor noise and vibration monitoring system 10 having the configuration as described above automatically notifies the household that generated the inter-floor noise and vibration when the inter-floor noise vibration occurs above the allowable reference value in an apartment house, thereby raising objections from the affected household. Objective and accurate data that can be used as evidence to recognize and respond voluntarily before filing, thus preventing intergenerational quarrels or disputes, and to claim damages from households affected by interfloor noise and vibration. Can provide.

In addition, by analyzing the properties of the noise source through frequency analysis, it is possible to identify the source of noise and vibration, and through this, it is possible to more effectively suppress the occurrence of noise and vibration. If it is identified, it can be judged as a problem of the building, so a request for improvement of the building can be made based on this.

As described above, embodiments of the present invention are not implemented only through the above-described apparatus and/or operation method, but through a program for realizing a function corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded, etc. It may be implemented, and such implementation can be easily implemented by an expert in the technical field to which the present invention belongs from the description of the above-described embodiment.
