As shown, the active noise control unit 120 of the active noise control device in a building of the present invention includes a collection information management unit 1100, an active noise generator management unit 1200, an active noise information control unit 1300, and a communication unit 1400. ) includes. The collection information management unit 1100 manages the collection information. Additionally, the active noise generator management unit 1200 manages the active noise generator 130.

The communication unit 1400 communicates with the reference collector 110 and the active noise generator 130 through a wired or wireless network 5000.

The collection information management unit 1100 includes a standard collection device management unit 1110, a standard collection information input unit 1120, and a standard collection information processing unit 1130.

And the standard collector management unit 1110 includes a standard collector register 1111 and a standard collector DB 1112.

Here, the reference collector registration unit 1111 registers necessary information related to the reference collector 110, including location information of the reference collector 110. The standard collector DB 1112 stores information registered by the standard collector register 1111. The reference collection information processing unit 1130 includes a reference collection information analysis unit 1131 and a noise space map generation unit 1132.

The reference collection information analysis unit 1131 analyzes the reference collection information.

The active noise generator management unit 1200 includes an active noise generator registration unit 1211.

Information on the active noise generator 130 registered in the active noise generator register 1211 is stored in the active noise generator DB 1212. The active noise generator management unit 1200 may include an active noise generator control unit 1220.

The active noise generator control unit 1220 generates control information to control the active noise generator 130. The active noise generator control unit 1220 operates the active noise generator 130 when the size of the noise of the reference collector 110 analyzed by the reference collection information analysis unit 1131 reaches a preset standard, such as being below the preset standard. A command to stop can be generated and transmitted to the active noise generator 130.

The active noise generator control unit 1220 operates when the size of the noise of the reference collector 110 analyzed by the reference collection information analysis unit 1131 exceeds the preset operation stop standard, or when the preset noise pattern is repeated or intermittently. When a preset operation start standard is reached, such as when an operation occurs, a command for starting the operation of the active noise generator 130 may be generated and transmitted to the active noise generator 130.

In addition, although not shown, a command to stop or start the active noise generator 130 is input through a user terminal such as the user's mobile terminal through the wired or wireless network 5000, and the input command is transmitted to the active noise generator 130. It can perform the function:

When leaving a space where the active noise generator 130 is installed, the active noise generator 130 can be turned off manually. However, if you go out without turning it off, you can use a user terminal such as a smart phone. The operation of the active noise generator 130 can be stopped.

The active noise information control unit 1300 uses the analysis information of the reference collection information analysis unit 1131 and the noise space map information of the noise space map generation unit 1132 to determine the preset noise at the location of the active noise generator 130. Generate estimated information.

The noise estimation information is location information of the active noise generator 130 and refers to generating expected noise information occurring at the location of the active noise generator 130 on the noise space map.

The expected noise information includes noise intensity information and noise wavelength distribution information for each time section estimated from the noise space map information corresponding to the 3D location information coordinate area of the active noise generator 130.

The active noise information generator 1320 generates active noise information to effectively cancel the noise based on the noise estimation information, based on the noise estimation information corresponding to the location of the active noise generator 130.

Meanwhile, the active noise information transmission unit 1330 performs a function of transmitting the generated active noise information to the active noise generator 130 through the wired and wireless network 5000. The noise space map generator 1132 generates a noise space map targeting a three-dimensional space using the collected information received from the reference collector 110. The key to creating a noise space map is to estimate how noise energy is spatially distributed from the estimated noise source.

The method by which the noise space map generator 1132 generates the noise space map is as follows.

The noise space map generator 1132 analyzes the noise intensity collected by at least three reference collectors 110 for each noise wavelength that is higher than the preset noise intensity with respect to the noise input, and determines the location of the estimated noise source. Estimate . This is because the positions of three or more reference collectors 110 are determined, and the noise energy of one noise source received by the reference collector 110 is inversely proportional to the square of the distance between the noise source and the reference collector 110.

For example, when the intensity of noise of a specific frequency received by reference collector a is 4A, and the intensity of noise received by reference collector b is A, the reference collector a is twice closer to the noise source than the reference collector b. There will be. With the reference collector a and reference collector b as one side, there are countless points corresponding to the distance ratio of 1:2 between the reference collector a and reference collector b. Meanwhile, if the intensity of noise received by the reference collector c is 1/4A, the distance ratio between the reference collector a and the reference collector c is 1:4.

In this way, the location of the noise source is estimated.

When the location of the noise source is estimated and the noise energy received by the reference collector 110 is calculated, the noise energy generated by the noise source can be calculated. In this way, the locations and generated noise energy of n (n is a natural number) noise sources are estimated.

When the reference collector 110 and the noise source are located at the same or equal height (normal noise is generated near the ground surface), at least three reference collectors 110 are used to estimate the location of the noise source. If the height of the noise source and the reference collector 110 are different, at least four reference collectors 110 are required.

The noise space map generator 1132 can generate a noise space map when the location of the estimated noise source and the noise energy generated by the estimated noise source are determined. When there are no buildings, the noise energy spreads in three dimensions, so the noise energy becomes smaller in inverse proportion to the square of the distance from the noise source.

Except in special cases, the noise source is close to the ground surface, and noise is not transmitted well below the ground surface. Assuming that all noise energy is transmitted to the ground space, the noise energy at the estimated location is inversely proportional to the square of the distance. , it will be doubled. This is because the surface area of the virtual sphere through which noise energy propagates is halved due to the presence of the ground surface.

If there is a building, the spatial distribution of noise energy is calculated by entering actual building conditions such as the location of the building, the ratio of noise energy absorbed by the ground surface, and the absorption or reflection of the exterior wall of the building, and through this, the noise space is calculated. Of course, you can create maps.

If the spatial distribution of noise is calculated for each noise source in the same manner as above, and the spatial distribution of noise is processed for each noise source, the entire noise space map is completed. The generated noise space map may be generated for each wavelength/wavelength band of the noise source. By utilizing the generated noise space map for each wavelength/wavelength band, noise estimation information for each wavelength/wavelength band of the active noise generator 130 can be generated through the noise estimation information generator 1310.

The active noise information generator 1320 may generate active noise information corresponding to the generated noise estimation information for each wavelength/wavelength band.

In special cases, the location of the noise source may be moved. This is especially true in the case of roadsides, where running cars are a major noise source, and because each car runs at a different speed, the moving speed and noise energy are different for each noise source. When a car moves at a certain speed, the wavelength changes due to the Doppler effect.

When the reference collector 110 measures the Doppler effect, the moving speed of the noise source can be calculated. Accordingly, it is possible to generate a noise space map in which the distribution of noise energy varies by time considering the movement speed for each noise source.

However, if the collection speed of the reference collector 110 and the information processing speed of the active noise control system are sufficiently fast, for example, if information is processed in units of 1/10 second or 1/100 second, the location of the moving car is Each information processing point can be treated like a fixed noise source.

The standard collection information analysis unit 1131 analyzes the average noise intensity for each noise wavelength input by time section, and if the dispersion value of the noise intensity for each noise wavelength for each time section falls within a preset range, it can be treated as homogeneous noise. . In this case, for homogeneous noise, the active noise information generator 1320 generates homogeneous active noise information for each wavelength.

The reference collection information analysis unit 1131 analyzes the collection information in preset time units, and if the noise intensity for each noise wavelength exceeds the preset range, or if noise of a specific noise wavelength is newly generated above the preset level, When it disappears, the occurrence of such noise fluctuations is transmitted to the noise estimation information generator 1310 or the active noise information generator 1320, so that active noise that matches the changing situation can be controlled. .

The active noise control system generates active noise information that the active noise generator 130 should generate for each active noise generator 130 and transmits it to the active noise generator 130. When there are two or more active noise generators 130 in one household, the active noise control system can generate different active noise information depending on the location of the active noise generators 130.

This is especially true if the household is an apartment that faces a road on one side and a non-road on the other, and has a window on the road side and a window on the non-road side as well. Since the noise information received from each window is different, different active noises are generated. occurrence is necessary.

The user can register detailed relative position information for each active noise generator 130 in the active noise control system. The active noise generator register 1211 receives various information related to the active noise generator 130 for the specific household through the wired or wireless network 5000.

The information of the registered active noise generator 130 includes the physical address, location, height of the household (number of floors of one's house, etc.), the number of active noise generators 130, the location of each active noise generator 130, and the active noise generator 130. This may be the environment in which the active noise generator 130 is located, such as whether the noise generator 130 is on the road. The information of the registered active noise generator 130 is stored in the active noise generator DB 1212.

Meanwhile, the standard collector registration unit 1111 registers all information related to the standard collector 110. Information related to the reference collector 110 includes location information (including height information) of the reference collector 110, area information (for example, an apartment complex, etc.), and surrounding environment information in the area where the reference collector 110 is installed. , This information is stored in the reference collector DB (1112).

The surrounding environment information includes building information (location, occupied space, height, exterior wall material (cement or glass exterior wall), etc.), relative location information between the building and the reference collector 110 (where in which building the reference collector 110 is located) Information such as whether it is installed), landscaping information (the presence or absence of landscaping trees such as trees, height of trees, etc.), distance information from the road, information on the number of passing vehicles or temporal distribution of passing vehicles, information on the average speed of passing vehicles, etc. .

The active noise control unit 120 having this configuration controls the reference collector 110 located within the area of the complex building and receives reference noise information from the reference collector 110. In addition, the active noise control unit 120 generates a noise space map for the reference noise collector using the location of the reference collector 110, the received reference noise information, and information about the building.

In addition, the active noise control unit 120 uses the location information of the active noise generator 130 located within the area of the building and the noise space map to generate active noise information that cancels out the noise received by the building.

The active noise generator control terminal may provide active noise information to an active noise generator module including a speaker module 3310 through a home network or other wired or wireless network 5000. Alternatively, if it includes an active noise generating module, the active noise generating module may provide a sound signal obtained by processing active noise information to the speaker module 3310.

FIG. 7 is a diagram showing the detailed configuration of the active noise generator 130 shown in FIG. 6, and is a configuration diagram of the active noise generator 130 assuming a case where there are multiple speakers as shown. As shown, the active noise generator 130 and the speaker may be equalized 1:1 (one speaker is controlled per active noise generator 130, and the active noise control system is controlled per active noise generator 130). (receives active noise to be generated by the speaker it controls), 1:n may correspond. Additionally, in the case of a 1:n correspondence, one active noise generator 130 operates by controlling n speakers.

The active noise generator 130 can receive active noise information to be generated from each speaker from the active noise control system.
