The sensor cable 100 may be installed on the floor surface of the indoor space for each household. The sensor cable 100 may be used as a sensor for detecting the vibration of the floor according to the movement of the resident. Here, it is illustrated that several sensor cables are installed in a lattice form for convenience, but in reality, one sensor cable is installed in a lattice form.

Referring to FIG. 2A , the sensor cable 100 according to the first embodiment is installed on the floor surface of the indoor space for each household, and may be inserted and installed inside a duct formed inside the floor surface. The sensor cable 100 may be installed to be spaced apart from the floor by a predetermined distance.

Referring to FIG. 2B , in order to measure the vibration generated on the floor, the sensor cable should be installed at a point where the maximum point of the amplitude at which a possible resonant frequency occurs. Therefore, if one sensor cable is to be used, it is preferable to install the sensor cable so that it passes through the center with the largest amplitude at the resonant frequency of the floor.

At this time, it is also possible to be installed in the longitudinal direction of the floor or installed in the width direction.

Referring to FIG. 2C , when the sensor cable is installed at a point where the maximum point of the amplitude at which a possible resonant frequency occurs, a harmonic component may also be measured. However, if the distance is short, it may be difficult to distinguish the amplitude of the fundamental resonant frequency from the amplitude of the harmonic component.

Therefore, if the sensor cables are installed to pass through the position where the amplitude is large at the resonant frequency and the position where the amplitude is large at the harmonic frequency, it is possible to measure the amplitude component at the resonant frequency and the harmonic frequency.

Referring to FIG. 2D , the sensor cable 100 according to the first embodiment may be installed in the inner center of the floor surface of the indoor space. Such a sensor cable 100 may be widely installed on the floor surface of the indoor space for each household of a common house such as, for example, an apartment.

Referring to FIG. 3 , as a result of applying an impact to the bottom surface of the rectangular structure and measuring the pressure value at the bottom surface, the thickness, width, length, and material constituting the structure of the rectangular structure were higher than the frequency of the amount of impact applied to the floor. It can be seen that the pressure value can be large at a natural frequency determined by Therefore, in the embodiment, when the pressure value is measured at the natural frequency that most affects the noise, the vibration value is measured.

The integrated management server 300 may measure the vibration value of the floor through the sensor cable 100 when the pressure value measured by the pressure measuring device is greater than or equal to a predetermined size. The integrated management server 300 may obtain the vibration value of the floor through the sensor cable 100 , compare the acquired vibration value with a predetermined threshold value, and determine whether there is inter-floor noise as a result of the comparison.

For example, the integrated management server 300 may calculate an average value of vibration values measured for a predetermined time and compare the calculated average value with a threshold value to determine whether there is noise between floors. That is, when the average value is greater than the threshold value, the integrated management server may determine that the noise between floors has occurred.

At this time, since it is possible to predict the size of the noise value according to the magnitude of the vibration value, it may be possible to predict whether inter-floor noise is generated based on the magnitude of the vibration value. Such a prediction may be made based on actually measured data.

The integrated management server 300 interworks with the warning generating device 400, and when it is determined that the inter-floor noise has occurred, generates a warning message for informing the resident that the inter-floor noise has occurred, and transmits the generated warning message to the warning generating device 400 ) can be sent to

You can decide whether to make noise between floors.

As an example, the integrated management server 300 may generate noise between floors if any one of the first and second vibration values obtained through the first line 110 and the second line 120 is greater than or equal to a threshold value. is determined to have occurred, and when both the first vibration value and the second vibration value are less than the threshold value, it may be determined that the inter-floor noise does not occur.

As another example, the integrated management server 300 calculates an average value of the first vibration value and the second vibration value measured through the first line 110 and the second line 120 , and when the calculated average value is equal to or greater than the threshold value It can be determined that only inter-floor noise has occurred.

The integrated management server 300 interworks with the warning generating device 400, and when it is determined that the inter-floor noise has occurred, generates a warning message for informing the resident that the inter-floor noise has occurred, and transmits the generated warning message to the warning generating device 400 ) can be sent to

You can check your health status.

The integrated management server 300 may generate a notification message for informing a pre-registered user, for example, a guardian of movement information, and transmit the generated notification message to the user terminal.

15 is a diagram illustrating a method for monitoring noise between floors according to a second embodiment of the present invention.

15, the integrated management server 300 according to the second embodiment of the present invention transmits a laser light signal through the first line 110 and the second line 120 of the sensor cable 100, and A laser light signal may be received through the first line 110 and the second line 120 ( S1504 ).

Next, the integrated management server converts the received laser light signal into an electrical signal and analyzes the converted electrical signal to obtain a first vibration value and a second vibration value (S1505).

Next, the integrated management server calculates an average value of the first vibration value and the second vibration value acquired for a predetermined time (S1506), and compares the calculated average value with a predetermined vibration threshold value to determine whether inter-floor noise is present (S1507) ).

Next, the integrated management server may generate a warning message for informing the resident that noise between floors has occurred (S1508) and transmit the generated warning message to the warning generating device 400 (S1509).

Next, upon receiving the warning message, the warning generating device 400 may output a predetermined alarm, for example, a warning phrase, a warning sound, and a warning lamp based on the received warning message (S1510).

In addition, the integrated management server calculates a first energy graph and a second energy graph based on the first vibration value and the second vibration value obtained for a predetermined time (S1511), and based on the calculated first energy graph and the second energy graph to calculate the movement information of the resident (S1512).

For example, as shown in FIG. 14B, movement information is calculated based on a graph in which information such as movement speed can be calculated based on the energy graph for each line of the sensor cable, and movement information of the resident is calculated based on the movement information calculated for each line. information can be calculated.

Next, the integrated management server may determine the state of the resident based on the calculated movement information (S1513). Here, the state of the resident can be divided into health, which appears to be active, and risk, which appears to be hardly active, depending on the amount of movement. The movement amount criterion for determining such a state may be set or changed by the user.

Next, the integrated management server 300 may generate a notification message for informing a pre-registered user, eg, a guardian, of movement information (S1514) and transmit the generated notification message to the user terminal (S1515).

Next, upon receiving the notification message, the user terminal may display the state of the resident on the screen (S1516).
