Description

Real-Time Interlayer Noise Monitoring System and Method for Pre-Management of Interlayer Noise Conflict}

The present invention can accurately measure the noise level above the reference noise level by precisely measuring the noise level, and in real time to share the fluctuation of the noise level actually felt by the noise victim with the noise generator based on the accurately measured noise level, and induce the noise to be reduced. The present invention relates to a real-time floor noise monitoring system and method for pre-existing floor noise conflict management.

The floor noise of the multi-family house is evaluated by direct impact noise with 1 minute equivalent noise measured at 1 minute intervals and the maximum noise level measured at the interval set by the operator, and by air transmission noise with 5 minute equivalent noise measured at 5 minute intervals. In addition, if the noise level is higher than the standard noise level specified for each type, it can be legally regulated.

However, the noise level obtained by period may vary in size depending on at what point the measurement section for obtaining the noise level is taken, and it is difficult to accurately reflect the degree of noise damage felt by a real person.

In addition, as the noise level is measured to detect only the occurrence of legal reference noise, the basis for arbitration can be obtained according to the noise level measurement result, but it cannot be used for the preliminary management of the process leading to the legal reference noise.

Moreover, the interlayer noise is difficult to resolve the conflict between the victims of the interlayer noise and the inducer even if the noise of the legal standard is determined by concealment, extinction, unpredictability, and closeness to everyday life.

In addition, the strength of the floor noise is subjective, and the characteristics transmitted according to the structure of the multi-unit house, it is difficult to resolve the conflict caused by the noise between floors only by legal standards.

On the other hand, Patent Registration No. 10-1305138, Patent Publication No. 10-2016-0095480, and Patent Publication No. 10-2016-0086433 has a technology for warning or alarm step by step depending on the size of the noise level, and exceeding the reference noise level Although warning or alarming techniques are mentioned in the number of times, these techniques are either preliminary warnings before reaching the legal standard, or they only comply with the legal standard for the number of times of the highest noise level.

That is, the intensity of the interlayer noise felt by a person is represented by a complex action of the magnitude of noise level and the interval between occurrences, which is difficult to accurately reflect since the prior art separates and judges it separately.

KR 10-1305138 B1 2013.08.30. KR 10-2016-0095480 A 2016.08.11. KR 10-2016-0086433 A 2016.07.20.

Therefore, an object of the present invention is to measure the noise level of the interlayer noise more precisely than in the prior art to obtain the noise level felt by the actual floor noise victim, and based on this, the indicator reflecting the real-time fluctuations of the interlayer noise intensity felt by the interlayer noise generator It is to provide a real-time floor noise monitoring system and method for pre-management of floor noise conflict that can be shared by each other, to induce the floor noise reduction activity of the noise generator.

In order to achieve the above object, the present invention, in the real-time floor noise monitoring system for the preliminary management of floor noise conflict, the noise level obtained from the sound of a predetermined set time interval is obtained in a relatively short period than the set time interval to record in a log file Measuring means for generating an event for a section in which a maximum noise level is equal to or greater than a reference noise level among the sections indicated by a period of a set time interval, and recording an event occurrence state to generate a recorded file; Evaluating means for weighting the number of event occurrences according to the difference between the maximum noise level and the reference noise level, calculating the cumulative weighted cumulative number, and selecting an alarm class according to the weighted cumulative number; Alarm means for notifying the notification subject which pre-sets the changed alarm grade whenever an alarm grade changes; Recording means for storing and managing log files and recording files; It includes.

In order to achieve the above object, the present invention provides a smart device (10) for periodically obtaining the noise level obtained from the sound of a predetermined time interval in the house of the apartment in the real-time floor noise monitoring method for the management of the floor noise conflict in advance Wow; The noise level is classified by the smart device 10 and collected in real time, and then made by the server 20 to notify according to the evaluation result of the noise level. In the smart device 10, the noise level is acquired at a relatively short period than the set time interval. A measurement step of generating an event for a section in which the maximum noise level is equal to or greater than the reference noise level among intervals indicated by a period of a set time interval, and transmitting a log file recording the noise level and a recording file recording the event occurrence situation to the server 20; An evaluation step of estimating, by the server 20, weighting the number of event occurrences according to the difference between the maximum noise level and the reference noise level, calculating a cumulative weighted cumulative number, and selecting an alarm class according to the weighted cumulative number; An alarm step of notifying, by the server 20, the notification subject which preset the changed alarm class whenever the alarm class is changed; And a recording step of storing and managing a log file and a recorded file in the server 20.

The present invention is different from the conventional method of acquiring the noise level for each cycle and determining whether the noise level is equal to or greater than the preset time interval set by the noise level, and applying the set time interval set by the noise level as it is. After acquiring the noise level at a period relatively shorter than the set time interval, the maximum noise level is determined by the period of the set time interval to determine whether the noise level is higher than the reference noise level. Therefore, the noise level can be precisely measured and accurate determination results can be obtained in the case of equivalent noise level. In the case of the highest noise level, it can be used as a data for noise analysis such as noise type and noise pattern.

In addition, the present invention determines the degree of noise damage according to the indicator (weighted cumulative number of times) reflecting both the magnitude and the number of occurrences of the noise level, by step by step alarm according to the noise damage degree, accurately reflects the degree of damage felt by the actual noise victim, It can induce noise reduction activities of noise generators.

The present invention according to the embodiment has the effect of indicating that the noise is reduced by the noise reduction activity of the noise generator in the indicator (weighted cumulative number), to tell the noise victim that the noise generator is performing the noise reduction activity, Thus, it is possible to induce the life by reducing the noise.

According to an exemplary embodiment of the present invention, by notifying according to the initial noise damage point determined as the 1 minute equivalent noise level and the 5 minute equivalent noise level, the alarm can be quickly alerted in advance of the long setting time interval of the equivalent noise level.

According to the present invention, the instantaneous recording file is additionally generated for the highest noise level, so that the noise of the highest noise level can be accurately obtained, the noise source can be used to discriminate the noise source, and the noise of the highest noise level can be easily reproduced. You can also confirm.

A component of the real-time floor noise monitoring system according to an embodiment of the present invention is a setting means (1) for setting whether to notify each subject and a notification level according to an alarm level, and generating an event when a noise level of more than a reference noise level occurs while measuring the noise level. Measuring means (2), reproducing means (3) for reproducing an event occurrence situation, and an evaluation means for accumulating the number of event occurrences by weighting them according to the noise level of the event occurrence interval, and selecting an alarm class according to the cumulative number of times. (4) alarm means 5 for real time notification of the alarm level to the notification subject whenever the alarm level is changed, and recording means 6 for storing and managing a log file recording the noise level and a recording file recording the event situation. .

It may be variously configured according to the arrangement of each component as described above, or may be implemented to operate by utilizing the resources of the device implementing the component.

Such various configurations and implementation manners should be regarded as modifications that can be made without departing from the scope of the present invention. Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. It explains so that self-implementation is easy.

Referring to the block diagram shown in FIG. 1, the real-time floor noise monitoring system according to the first embodiment of the present invention may include setting means 1, measuring means 2, and reproducing means implemented in the smart device 10. 3) and an evaluation means 4, an alarm means 5 and a recording means 6 implemented in the server 20 connected to the smart device 10 through a communication network.

That is, the real-time floor noise monitoring system according to the first embodiment of the present invention comprises a smart device 10 having a setting means 1, a measuring means 2 and a reproducing means 3, an evaluation means 4, It can be seen that it consists of a server 20 having an alarm means 5 and a recording means 6.

The smart device 10, which may be a smartphone or tablet PC as an example, includes a user interface 12 for touch input and screen output, a microphone 13 for receiving an electric sound signal by receiving sound, and an electric sound signal as a sound. A speaker 14 for outputting, a memory 15 for storing data, and a processor 11 for controlling the operation of the smart device 10 are provided.

Here, the setting means (1), the measuring means (2) and the reproducing means (3) are installed and executed in the processor 11, so that the user interface 12, the microphone 13, the speaker 14 and the memory 15 It is implemented as a noise measurement application that performs the setup function using), noise level measurement function and noise reproduction function.

Referring to FIG. 2, the smart device 10 installed with the noise measuring application that implements the functions of the setting means 1, the measuring means 2, and the reproducing means 3 measures the noise level in each house of the apartment house. It is used as a measuring device.

The evaluating means 4, the alarming means 5 and the recording means 6 are built in the server 20 which allows the noise measuring application to communicate with each smart device 10 on which the noise measuring application is installed and executed. Enable evaluation, alarm and recording functions.

Although FIG. 2 illustrates a manager terminal 30 as a subject to be notified according to an alarm function, the subject to be notified is not limited to the manager terminal 30, and various notifications are made by the setting means 1 as described below. Can be selected among the subjects.

The setting means 1 selects at least one of the highest noise level, the 1 minute equivalent noise level and the 5 minute equivalent noise level by the user of the smart device 10 through the user interface 12. And setting an alarm class according to the weighted cumulative number and setting whether to notify each alarm level and whether to notify.

3 is an exemplary view of a setting screen by the setting means 1.

First, Figure 3 (a) is a screen for setting the type of noise level to measure and the alarm class according to the cumulative number of weights, the maximum noise level (LAmax), 1 minute equivalent noise level (1 minute LAeq) and 5 minutes equivalent noise level (5 minutes) LAeq) was selected to measure all kinds of noise levels.

In addition, the alarm level is set to be raised in the order of the alarm release (or a quiet state), a preliminary alarm, an alarm and a serious alarm, and can be arbitrarily set a level corresponding to the weighted cumulative number to be described in detail below. That is, the alarm level is set to increase as the weighted cumulative number increases. Accordingly, when the cumulative weighted number decreases, the alarm level is lowered, and the alarm level according to the weighted cumulative number can also be determined by the noise measurer.

Here, the alarm release (or a quiet state) refers to a state in which there is no need for notification because no interlayer noise has occurred, or a state in which the alarm is canceled because the interlayer noise has not occurred for a predetermined time after the previous layer noise has occurred.

Preliminary alerts are alerts that provide preliminary notification, although floor noise does not meet legal standards.

An alarm is an alarm that is notified when the floor noise is above the legal standard.

Severe alerts are alerts when floor noise is above legal standards and causes serious damage.

The alarm class is not limited to this and may be further subdivided.

3 (b) is a screen for setting the notification subject and the notification level according to the alarm level, and it is possible to select the notification object and to set the notification level according to the alarm level for each selected notification object.

The notification subject may include an inducer causing the noise between floors, an administrative office of a multi-family house (for example, the manager terminal shown in FIG. 2), an inter-floor noise management committee, an inter-floor noise measurement agency, and the like, and may be added. The smart device 10 also includes a measurer to measure the noise. Only the target selected among these is selected as the notification target.

Referring to the setting screen shown in the figure, when the smart device 10 is configured with a smartphone that is not used as a mobile communication terminal, the user's smartphone is notified. Have the noise generator notify you only of alerts and critical alerts.

In an embodiment of the present invention, it is also possible to select whether to notify the situation of starting the noise measurement or ending the measurement.

On the other hand, whether or not the alarm is released (or at a quiet temperature) is determined after the noise level is measured until the first occurrence of the inter-floor noise, that is, the initial quiet temperature without the need to be notified since the inter-floor noise has not occurred, and the inter-floor noise previously. After the occurrence of the occurrence of the noise between floors, the alarm release state may be set separately. For example, the inducer is not notified of the calm state, but only the alarm release state.

In this way, the matter set by the setting means 1 is transmitted to the server 20 through a communication network, and is reflected in the operation of the evaluation means 4 and the alarm means 5.

Hereinafter, after selecting all of the maximum noise level, the 1-minute equivalent noise level, and the 5-minute equivalent noise level, the operation of the component when starting the noise level measurement will be described.

The measuring means 2 acquires a noise level, buffers an electric sound signal obtained through the microphone 13 in the memory 15, records the noise level in a log file of the memory 15, generates an event according to the noise level, and then generates an event. The sound signal containing the occurrence situation is extracted from the buffer of the memory 15 to generate a recording file.

Conventional noise measuring instruments for measuring the noise level is obtained from the sound pressure of the sound signal obtained by receiving the sound of a predetermined time interval determined by the type of noise level.

Specifically, the 1 minute equivalent noise level is obtained from the sound pressure of the sound signal measured for 1 minute because the set time interval is set to 1 minute, and the 5 minute equivalent noise level is measured for 5 minutes because the set time interval is set to 5 minutes. Obtained from the sound pressure of an acoustic signal. It is known that the maximum noise level is not set to a predetermined interval, so that the measurer sets the interval at an appropriate interval and obtains the maximum value of the set interval.

In addition, the conventional noise measuring instrument periodically obtained a noise level at a set time interval. That is, a 1 minute equivalent noise level is obtained at a predetermined 1 minute period, a 5 minute equivalent noise level is obtained at a predetermined 5 minute period, and a maximum noise level is obtained at a interval set by a measurer.

However, in the present invention, the noise level is obtained at a period relatively shorter than the set time interval.

Specifically, one minute equivalent noise level is obtained at a period shorter than one minute, five minute equivalent noise level is obtained at a period shorter than five minutes, and a maximum noise level is obtained at a period shorter than a set time interval set for the highest noise level. Applicants of the present invention, in consideration of the pattern of the inter-layer noise caused by various kinds of noise source, to set the maximum noise level to 4 seconds, the highest noise level is obtained in a relatively short period than 4 seconds.

On the other hand, in order to match the timing of obtaining the noise level with the set time interval, the noise level was obtained at 1 / n (n is an integer) period of the set time interval. According to the exemplary embodiments illustrated in FIGS. 4 to 6, the maximum noise level is obtained at a 0.5 second period, which is 1/8 of a set time interval (4 seconds), and the 1 minute equivalent noise level and the 5 minute equivalent noise level are the highest noise level for precision measurement. In the same manner as in the 0.5 second cycle, the maximum noise level was obtained.

That is, the present invention is the same as the conventional method in that the noise level to be compared with the reference noise level is obtained at a set time interval, but the present invention differs from the conventional method in that the noise level is first obtained in detail and then secondarily selected.

Thus, when one-minute equivalent noise and five-minute equivalent noise level to be compared with the reference noise level are obtained, conventionally, a noise value having a different value is obtained according to the difference of the start point of measurement, and thus a value lower than the noise level of the actual maximum value generated within the set time interval is obtained. Although the noise level is obtained, in the present invention, since the noise level is precisely obtained at intervals shorter than the set time interval, the maximum value is selected, thereby obtaining the actual maximum noise level.

With respect to the maximum noise level, a plurality of reference noise levels or more noise levels appearing within a set time interval (4 seconds in the embodiment of the present invention) can also be obtained, and can be utilized for analysis of interlayer noise such as noise source type, noise level pattern, and the like, as described below. It can also be used to establish a reference point for creating instantaneous recordings.

The event is generated for the corresponding section when there is a section in which the maximum noise level is higher than the reference noise level after obtaining the maximum noise level among the intervals indicated by the period of the set time interval for each type of noise level.

The standard noise level for determining whether an event occurs may apply a legal standard prescribed for each noise level, but may not be limited thereto. For example, by using the setting means (1) it is possible to arbitrarily modify the reference noise level according to the environment of the apartment house.

However, the event generated according to the 1-minute equivalent noise level and the 5-minute equivalent noise level is generated according to the maximum noise level among the noise levels in the event generation section at the end of the event generation section, and thus occurs later than the time when the noise level is higher than the reference noise level.

However, it is preferable to promptly alarm when a noise level of more than the reference noise level occurs for the first time in the alarm release state or the constant temperature state, to induce noise reduction of the noise generator.

Thus, in the embodiment of the present invention, the measurement means 2 receives the weighted cumulative number calculated by the alarm means 5, so that the noise level more than the reference noise level in the alarm release state or the constant temperature state where the weighted cumulative number is '0' Generates an event at the first appearing time, and then generates an event at a set time interval.

Since the event is generated even at the end of the section in which the noise level is higher than the reference noise level, the cumulative number is adjusted as described below.

Since the highest noise level can generate an event at a very short period compared to the one-minute equivalent noise level and the five-minute equivalent noise level, it is not necessary to generate the event at the first occurrence of the noise level above the reference noise level. However, when the set time interval of the highest noise level is set to a very large value, it is preferable to generate an event at the time when the noise level above the reference noise level first appears, similarly to the one-minute equivalent noise and the five-minute equivalent noise. Of course, since the event is generated at the end of the interval in which such an event occurs, the number of times accumulated in the weighted cumulative number to be described later should be adjusted like the 1 minute equivalent noise and the 5 minute equivalent noise.

The recording file is a file recording noise exceeding a reference noise level, and includes a long time recording file and an instantaneous recording file.

Thus, the long time recording file is obtained by recording from a time point five minutes ahead of the start point of the event section in which the event occurs during the search period from five minutes later than the end point of the event section. In practice, it is preferable to include the 6 minutes before and after the event section in consideration of the 1 minute equivalent noise level. The long time recording file obtained by recording as described above is a file generated in the prior art, so that the situation before and after the occurrence of noise can be known.

The instantaneous recording file is a recording file that has not been produced in the prior art, and is additionally generated with respect to the maximum noise level in order to obtain only an acoustic signal of noise that caused interlayer noise.

Specifically, the instantaneous recording file is obtained by recording from the point of time 1 to 3 seconds ahead to the point of time 3 to 10 seconds later on the basis of the point of time exceeding the reference noise level first in the event occurrence interval.

Since the maximum noise level is measured for the direct impact noise, considering the pattern of the direct impact noise, when the recording starts before the time shorter than 1 second or when the recording ends after the time shorter than 3 seconds, the noise signal is detected. It may not be possible to record completely, and if the recording starts at a time earlier than 3 seconds or the recording ends at a time delayed longer than 10 seconds, the interval where no noise signal is generated may be too long. Thus, the recording time of the instantaneous recording file is preferably set within the above range.

As shown in FIG. 4, recording was performed from 1 second to 4 seconds later.

A detailed embodiment will be described with reference to the noise level graph shown in FIGS. 4 to 6.

Referring to the maximum noise level graph shown in FIG. 4, the highest noise level is obtained by setting 1/8 of the set time interval (T_0 = 4 seconds) as the measurement period (Td = 0.5 second), and set time interval (T_0 = 4 seconds). Event can be triggered at the interval of.

Since eight peak noise levels are obtained for each interval of the set time interval (T_0 = 4 seconds), after searching the maximum value among the eight highest noise levels, an event is generated when the maximum value exceeds the reference noise level, and the first time exceeding the reference noise level is obtained. The instantaneous recording file and the long time recording file are generated based on the occurrence time of the noise level (t_0). In this case, since the reference noise level applied during the day and the reference noise level applied at night are different, the reference noise level is applied by dividing the day and night.

The instantaneous recording file is generated by recording from 1 second to 4 seconds after the first time point (t_0) when the noise level is higher than the reference noise level within the interval in which the event is generated.

Long time recording files are recorded from 6 minutes before to 6 minutes after the first time (t_0) when the noise level above the reference noise level is generated, but it is recorded from 6 minutes before the event occurrence section to 6 minutes after the event occurrence interval. You may also do it. Of course, if an additional event occurs during recording, it is better to increase the recording time and generate one long recording file.

Referring to the one-minute equivalent noise level graph shown in FIG. 5, the one-minute equivalent noise level is set to a measurement period (0.5 seconds in the embodiment of the present invention) which is shorter than the set time interval (T_1 = 1 minute) of the one-minute equivalent noise level. Obtain a maximum value of 1-minute equivalent noise level for each section of the set time interval (T_1 = 1 minute) period, generate an event when the reference noise level is higher, and generate a long time recording file.

On the other hand, the event is further generated at a time point t_1 at which the one-minute equivalent noise level of the reference noise level or more first appears.

The reference noise level to be applied to the 1-minute equivalent noise level may be different from the standard noise level to be applied to the maximum noise level, but the same applies to day and night.

The long time recording file is obtained by recording from 6 minutes before the start point of the event occurrence section to 6 minutes after the end point of the event occurrence section.

Referring to the five-minute equivalent noise graph shown in FIG. 6, a five-minute equivalent noise level is obtained using a measurement period (Td = 0.5 seconds in the embodiment of the present invention) which is shorter than a set time interval (T_5 = 5 minutes). After a maximum of 5 minutes equivalent noise level is obtained for each section of the set time interval (T_5 = 5 minutes), it is determined whether to generate an event, and a long time recording file is generated when an event is generated. Of course, the reference noise level to be applied may be different from the highest noise level and one minute equivalent noise level.

An event is additionally generated at a time point t_5 when the equivalent noise level of 5 minutes or more above the reference noise level first appears.

On the other hand, when noise is generated for each kind of event, but when recording for generation of a recording file for a long time, if an event occurs for any one type of noise, recording starts, and an event is generated for any kind of noise during recording. The recording time is extended based on the additional section. Accordingly, the sound level may be generated as one long time recording file without distinguishing the type of noise level. Of course, if an event occurs after creating a long recording file, a new long recording file is generated.

The measuring means 2 periodically transmits a log file recorded for each type of noise level to the server 20, and transmits event related information together with the log file when an event is generated.

Of course, it is preferable to transmit a log file that records only the additionally recorded noise level by transmission period.

The log file to be transmitted includes a log file of maximum noise, a log file of 1 minute equivalent noise, and a log file of 5 minute equivalent noise. Therefore, the log file may be transmitted at a corresponding interval of setting time intervals, In order to monitor the equivalent noise level in which the time interval is relatively long compared to the highest noise level, it is preferable to use the shortest period (the set time interval of the highest noise level) as the transmission period.

The event related information transmitted when an event is generated includes an event message, an instantaneous recording file, and a long recording file indicating that an event has occurred.

Here, the event message is divided into a periodic event message generated at a set time interval for each type of noise level, and an initial event message generated when a noise level of more than a reference noise level is generated for the first equivalent noise level and 5 equivalent noise levels for the first time.

In addition, since the event messages for each cycle are generated at set time intervals, if the set time intervals are set as log file transmission cycles as in the embodiment of the present invention, the event messages may be immediately transmitted together with the log files.

Instantaneous recording files and long recording files are transmitted along with the log files at the time of the first log file transmission.

On the other hand, the event-related information may include the maximum noise level of the event generation section, but if not included, it should be to find the maximum noise level from the log file in the following evaluation means.

In addition, the event-related information may include the time when the noise level of the first noise level or more than the reference noise level for the first minute equivalent noise level and 5 minutes equivalent noise level, but not including the first, the set time interval of the highest noise level in the following evaluation means ( T_0 = 4 seconds) should be searched from the log file for 1 minute equivalent noise and 5 minutes equivalent noise.

The reproducing means 3 outputs a sound signal of a stored recording file or a recording file that can be received by being transmitted to the server 20 through the speaker 14, and obtains a new noise level for the output sound signal. The screen is output through the screen, and the frequency analysis result of the sound signal is output on the screen. Since the reproducing means 3 can be configured by employing the technique of Patent No. 10-1798422, detailed description thereof will be omitted.

Next, the evaluation means 4, the alarm means 5, and the recording means 6 built in the server 20 will be described.

When the evaluation means 4 receives the event-related information together while periodically receiving the log file, the evaluation means 4 calculates the cumulative number of weights for each noise level according to the event message included in the event-related information, According to the noise level, the alarm class is selected. Of course, the weighted cumulative number of times is initialized to '0' in the alarm release state or the constant temperature state. The alarm class is selected according to the setting according to the magnitude of the weighted cumulative number as described with reference to FIG. 3 (a).

As described above, the event message is divided into a periodic event message generated at a set time interval for each type of noise level, and an initial event message generated when a noise level of more than a reference noise level is generated for the first equivalent noise level and a 5-minute equivalent noise level for the first time. .

Thus, when the event-related information includes the event message for each cycle, the weighted cumulative number is calculated by weighting the number of event occurrences according to the difference between the maximum noise level and the reference noise level of the event generation interval.

When the event-related information includes the first event message, the weighted cumulative number of related equivalent noise levels during the one-minute equivalent noise level and the five-minute equivalent noise level is increased once without weight. Subsequently, when the event message for each cycle that is set at the end of the event occurrence interval that caused the first event message is received, one time (that is, the first event) is weighted according to the difference between the maximum noise level and the reference noise level of the event occurrence interval. Accumulate according to the weighted cumulative number).

Referring to the graphs illustrated in FIGS. 4 to 6, a specific embodiment will be described. When the maximum noise level shown in the event occurrence interval is larger than the reference noise level by less than the predetermined value (△), the weighted cumulative number is increased once, and the predetermined value is increased. If larger than (△), increase the cumulative weighting count twice. Of course, the weight is divided into two stages based on the predetermined value Δ, but the weight may be divided into three or more stages.

That is, the cumulative weighting count reflects both the number of event occurrence intervals and the noise intensity in the event occurrence interval, and thus may be an index representing the noise damage degree felt over time.

As illustrated in FIG. 5 and FIG. 6, for the 1 minute equivalent noise level and the 5 minute equivalent noise level, an initial event message is additionally generated at a time point t_1 and t_5 when a noise level higher than the reference noise level is first displayed in the alarm release state or the constant temperature state. In addition, the noise level at this time is less than the said predetermined value (triangle | delta). Accordingly, the weighted cumulative number of times is increased by one time at this time t_1 and t_5, and the number of cumulative accumulations is performed once according to the event message for each cycle generated for the section to which the time points t_1 and t_5 belong. In this case, the number of times according to the first event message is not duplicated.

On the other hand, the evaluation means may reduce the alarm level by subtracting the cumulative number of times as the time when the event does not occur.

For example, when the time when the event does not occur 1 hour has elapsed, the weighted cumulative number of times may be subtracted by one after the time elapses to have a weighted cumulative number of '0' which is an alarm release state. Of course, the alarm level is modified and lowered according to the weighted cumulative number obtained by subtraction.

By lowering the alarm level in this way, it is possible to reflect that the noise damage degree felt by a person changes over time.

The alarm means 5 notifies the notification subject of the changed alarm level whenever the alarm level changes.

When the notification time due to the change of the alarm level is examined, the notification time is determined according to the period of the set time interval for each type of noise level, but for 1 minute equivalent noise level and 5 minutes equivalent noise level, Is added. Of course, a predetermined time as much as a transmission / reception time and a signal processing time is delayed until the event related information is received from the smart device and notified.

As described above with reference to FIG. 3 (b), the notification target is set and whether or not the notification target is set for each alarm level is also set.

At the time of notification, if any one of the plural noise levels has a change in the alarm level, it is notified, and the alarm level according to the noise level, the event occurrence time, the measurement position (the location of a smart device or the room of a common house), and the warning message for each alarm level The notice may be sent by sending a notice.

The notice of the notice may vary according to the type of the terminal to be notified, for example, may use SMS, ARS, and the like, and may use a data transmission method in connection with a management committee or a measurement agency.

On the other hand, as shown in Fig. 4 (b), when the notification target to notify the start of the noise level measurement or the end of the noise level measurement is set in the measurement means 2, the measurement start time or the measurement end time is received from the measurement means (2) Have a notice.

The recording means 6 stores and manages the log file and the instantaneous recording file transmitted from the measuring means 2 of the smart device 10 in the DB 6a, and also stores the long time recording file separately received in the DB 6a. Manage. Of course, it stores and manages by smart device (10).

In addition, the recording means 6 stores and manages the event occurrence history, the change history of the weighted cumulative number, the change history of the alarm class, and the notification history by the smart device 10.

It is preferable that the recording means 6 can transmit the information requested by the notification target among the stored and managed information. For example, a recording file is sent to the inducer during the notification, so that the user can reproduce the noise generated by the user.

FIG. 7 is a flowchart illustrating a real-time interlayer noise monitoring method for pre-layer noise conflict management according to an exemplary embodiment of the present invention made by the system described with reference to FIGS. 1 to 6.

The real-time floor noise monitoring method performed according to the flowchart of FIG. 7 includes a setting unit 1, a measuring unit 2, and a reproducing unit 3 as described above. And, by the evaluation means (4), the alarm means (5) and the recording means (6) by the server 20 to divide the noise level by the smart device 10 and collect in real time and to alarm according to the evaluation result of the noise level Since the detailed description is omitted, the description is mainly focused on the main technical contents.

First, in the smart device 10 to measure the noise level, referring to FIGS. 3 and 4, as described above, the noise level to be measured, the alarm class corresponding to the cumulative cumulative number of noise levels, the notification subject to notify the notice, and whether to notify the alarm class , And whether or not the measurement start / end notification is set by the setting means 1, and performs the setting step (S10) of transmitting the setting matters to the server 20.

Here, the noise level is classified into the highest noise level, the 1 minute equivalent noise level and the 5 minute equivalent noise level, and allows at least one to be selected.

The setting step S10 may be set to notify the start of noise level measurement or the end of the noise level measurement.

Next, when the noise level is started to be measured by the smart device 10 in the house of the apartment house, the measuring means 2 transmits the measurement start time to the server 20, and then measures the noise level of the set type (S20). ).

In the measuring step (S20), the noise level is obtained at a relatively short period (Td) than the set time intervals (T_0, T_1, T_5) to generate a recorded log file for each type of noise level (S21, S21 '). The acquisition periods Td of the highest noise level, the 1-minute equivalent noise level, and the 5-minute equivalent noise level are the same, but 1 / n (n is a natural number) of the set time interval corresponding to the highest noise level.

Then, when the period of the set time intervals T_0, T_1, T_5 elapses (S22) while acquiring and recording the noise levels (S21, S21 '), the maximum value of the noise levels of the immediately set time intervals T_0, T_1, T_5 is reached. Acquiring the noise level (S23), if the maximum noise level is less than the reference noise level (S24), and transmits the log file of the noise level recorded during the previous set time intervals (T_0, T_1, T_5) to the server (20) (S24 ').

According to an embodiment of the present invention, a log file for each type of noise level is generated and transmitted using the minimum interval as a transmission period among the set time intervals T_0, T_1, and T_5 which are different for each type of noise level. That is, the 1 minute equivalent noise level and the 5 minute equivalent noise level do not generate and transmit log files at the corresponding set time intervals (T_1, T_5), but record the log files divided by the period of the set time interval (T_0) of the highest noise level. Create and send.

If the maximum noise level is higher than the reference noise level (S24), it generates a cycle-by-cycle event and generates a recording file (S25), and log files and event related information (event messages and sound levels) recorded during the set time intervals (T_0, T_1, T_5). Record file) to the server 20 (S25 ').

Of course, the set time intervals (T_0, T_1, T_5) are divided into different noise levels to generate events for each cycle according to each maximum noise level, and after generating an event for any one type of noise level, Create and send information. The recording file is an additional recording file for the event occurrence section, a file recorded for a time including 5 minutes before and after, and the highest noise level, and is based on the first occurrence of the noise level above the reference noise level within the event occurrence section. It is a file recorded from the point of time 3 ~ 10 seconds delayed by ~ 3 seconds, and it is sent with the event-related information according to the transmission period that comes first after creation.

Meanwhile, the 1-minute equivalent noise level or the 5-minute equivalent noise level may be generated by adding an initial event. That is, after the noise level is started to be measured and the noise level is acquired and recorded (S21, S21 '), the first event is generated in accordance with the time when the noise level above the reference noise level first appears. In addition, while acquiring and recording the noise level even after notifying from the evaluation means 4 that the weighted cumulative number exceeds' 0 'and then subtracting it to' 0 '(S21, S21'), a noise level of more than the reference noise level first appears. Raise the first event in time. After generating the first event, the event is generated according to the period of the set time interval for each noise level.

When generating the first event does not generate a recording file, only the first event message to inform the server 20 in the event-related information.

When the noise level is finished, the end point is transmitted to the server 20.

By performing the measuring step S20 as described above, the evaluation means 4 of the server 30 receives and receives the log file or the event related information (S31), and then weights the cumulative number of times according to whether or not the event related information is received. In step S32, the evaluation step S30 is performed to correct the alarm level according to the addition and the decrease of the weighted cumulative number of times (S33).

Here, the weighted cumulative number is a cumulative number assigned to the number of event occurrences according to the difference between the maximum noise level and the reference noise level of the event occurrence interval, and starts from '0' at the time of measuring the noise level.

The weighted cumulative number is increased by '1' each time an event occurs, but may be increased to a value greater than '1' depending on the magnitude of the maximum noise level.

In addition, the weighted cumulative number of 1-minute equivalent noise and 5-minute equivalent noise was increased at the time of the first event. After determining the maximum noise level of the generated section and accumulating the weighted number of times according to the difference between the maximum noise level and the reference noise level, the accumulated value is accumulated except the accumulated number according to the first event.

It may be subtracted as the time for which an event does not occur elapses, and may be set to an initial value of '0'.

As such, the cumulative number of weights varies depending on the event, so that the alarm level selected according to the weighted cumulative number also changes.

When the alarm level is changed in this way, the alarm means 5 performs an alarm step S40 of notifying the notice to the notification subject of the changed alarm level.

Therefore, whenever the event occurs, the alarm level is changed and notified.However, the 1-minute equivalent noise level and the 5-minute equivalent noise level are notified even when the noise level above the reference noise level is first displayed with the weighted cumulative number of '0'. However, at the end of the interval, notification may or may not be made, depending on the magnitude of the maximum noise level.

At this time, the notification target set in the setting step (S10) is notified, but notified only when the alarm class is set to notify.

Of course, if any one of the plural kinds of noise levels corresponds to the notification target and the alarm level, the notification is included in the notice.

After the notification, the log file, the instantaneous recording file, the event occurrence history, the change history of the weighted cumulative number, the change history of the alarm class, and the notification history are also stored and managed by the smart device 10. Of course, if the recording file is additionally transmitted for a long time, the storage management.
