도 4는 본 발명에 따른 실내환경 모니터링 과정을 나타낸 것이다. 4 shows an indoor environment monitoring process according to the present invention.

도 4의 각 단계는 실내환경 플랫폼(100)에서 수행되며, 구체적으로 실내환경 플랫폼(100)의 제어부(104)가 실내환경 모니터링 알고리즘을 실행하여 각 단계를 처리한다. Each step of FIG. 4 is performed on the indoor environment platform 100, and specifically, the control unit 104 of the indoor environment platform 100 executes the indoor environment monitoring algorithm to process each step.

도 4를 참조하면, 먼저 실내환경 플랫폼(100)은 사용자 단말(200)로부터 환경센서(300)의 식별정보를 수신하여 내부 데이터베이스(DB)에 등록한다(S100). Referring to FIG. 4 , first, the indoor environment platform 100 receives identification information of the environmental sensor 300 from the user terminal 200 and registers it in the internal database DB (S100).

이후, 실내환경 플랫폼(100)은 환경센서(300)로부터 일정 시간 간격으로 센서신호를 수신한다(S102). 센서신호가 수신되면, 실내환경 플랫폼(100)은 센서신호를 처리하여 실내환경값(온도값, 습도값, 미세먼지농도, 소음레벨, 진동세기)을 생성한다(S104). 본 발명에 따른 환경센서(300)는 온도센서, 습도센서, 미세먼지센서, 소음센서 및 진동센서로 구성되어 있어서, 센서신호는 온도센서신호, 습도센서신호, 미세먼지센서신호, 소음센서신호 및 진동센서신호를 포함한다. Thereafter, the indoor environment platform 100 receives a sensor signal at regular time intervals from the environment sensor 300 (S102). When the sensor signal is received, the indoor environment platform 100 processes the sensor signal to generate indoor environment values (temperature value, humidity value, fine dust concentration, noise level, and vibration intensity) (S104). The environmental sensor 300 according to the present invention is composed of a temperature sensor, a humidity sensor, a fine dust sensor, a noise sensor and a vibration sensor, and the sensor signals include a temperature sensor signal, a humidity sensor signal, a fine dust sensor signal, a noise sensor signal and Includes a vibration sensor signal.

실내환경 플랫폼(100)은 실내환경값에 근거해 실내환경 인자(온도, 습도, 미세먼지, 소음, 진동)의 환경지수를 구하고, 각 환경지수를 합산하여 통합 환경지수를 산출한다(S106).The indoor environment platform 100 calculates an environmental index of indoor environmental factors (temperature, humidity, fine dust, noise, vibration) based on the indoor environment value, and calculates an integrated environmental index by summing each environmental index (S106).

본 발명의 실시예에서, 각 실내환경값이 최적 범위에 존재하면 환경지수 20점을 부여하고, 최적 범위를 벗어난 경우 일정한 점수를 감산하는 방식으로 각 실내환경 인자의 환경지수를 구할 수 있다. In an embodiment of the present invention, if each indoor environmental value is within the optimal range, 20 environmental index points are given, and when it is out of the optimal range, the environmental index of each indoor environmental factor can be obtained by subtracting a certain score.

예를 들어, 온도의 환경지수를 구할 때, 냉방(여름) 시의 온도값이 24~28도 범위에 있을 때 환경지수 20점이 되고, 난방(겨울) 시의 온도값이 18~24도 범위에 있을 때 온도의 환경지수가 20점이 될 수 있다. For example, when calculating the environmental index of temperature, when the temperature value during cooling (summer) is in the range of 24-28 degrees, the environmental index becomes 20 points, and when the temperature value during heating (winter) is in the range of 18-24 degrees When there is, the environmental index of temperature can be 20 points.

습도의 환경지수를 구할 때, 온도에 따라 최적의 습도가 달라지므로 온도 18~20도에서 습도값이 50~60% 범위, 온도 21~23도에서 습도값이 40~50% 범위에 있을 때 습도의 환경지수가 20점이 될 수 있다. When calculating the environmental index of humidity, the optimum humidity varies depending on the temperature, so when the humidity value is in the range of 50 to 60% at a temperature of 18 to 20 degrees, and when the humidity value is in the range of 40 to 50% at a temperature of 21 to 23 degrees. The environmental index of can be 20 points.

미세먼지(PM 10)의 환경지수를 구할 때, 미세먼지농도가 0~30(㎍/㎥) 범위에 있을 때 미세먼지의 환경지수는 20점이 될 수 있다. When calculating the environmental index of fine dust (PM 10), when the fine dust concentration is in the range of 0 to 30 (㎍/㎥), the environmental index of fine dust can be 20 points.

이와 같이, 각 실내환경 인자의 환경점수에 최고점 20점을 부여하여 통합 환경지수 100점을 기준으로 환경상태를 매우 나쁨. 나쁨, 보통, 좋음, 매우 좋음으로 분류하여 모니터링할 수 있다. In this way, the highest score of 20 is given to the environmental score of each indoor environmental factor, and the environmental condition is very bad based on 100 points of the integrated environmental index. It can be monitored by classifying it as bad, average, good, and very good.

실내환경 플랫폼(100)은 실내환경값 중에서 소음레벨이 소음 기준치(38dB) d이상인지를 확인하여(S108), 소음 기준치 이상인 경우 진동센서로부터 수신된 진동센서신호를 분석한다(S110).The indoor environment platform 100 checks whether the noise level is greater than or equal to the noise reference value (38 dB) d among the indoor environment values (S108), and if it is greater than the noise reference value, analyzes the vibration sensor signal received from the vibration sensor (S110).

1차 진동 분석 단계(S110)에서, 실내환경 플랫폼(100)은 진동센서신호를 시간 영역(time domain)에서 분석하여 얻은 평균 진동값(RMS)을 제1 기준값과 비교한다(S112). In the first vibration analysis step (S110), the indoor environment platform 100 compares the average vibration value (RMS) obtained by analyzing the vibration sensor signal in the time domain with a first reference value (S112).

도 5는 진동센서신호를 시간 영역에서 분석하는 것을 나타낸 것이다. 5 shows the analysis of the vibration sensor signal in the time domain.

도 5를 참조하면, 시간에 따른 진동세기를 확인할 수 있는데, (a)는 일반적인 상황에서의 진동 상태를 나타내고, (b)는 바람에 의한 진동 상태를 나타내고, (c)는 충격에 의한 진동 상태를 나타낸다. Referring to FIG. 5 , it is possible to confirm the vibration intensity according to time, (a) shows a vibration state in a general situation, (b) shows a vibration state due to wind, and (c) shows a vibration state due to impact indicates

일반적인 상황의 진동 상태에서 구한 평균 진동값은 제1 기준값보다 작으며, 바람에 의한 진동 상태와 충격에 의한 진동 상태에서 구한 평균 진동값은 제1 기준값보다 크다. The average vibration value obtained in the vibration state of a general situation is smaller than the first reference value, and the average vibration value obtained in the vibration state by wind and the vibration state by impact is greater than the first reference value.

따라서 평균 진동값이 제1 기준값 미만이면, 소음이 실제 소리에 의해 발생한 것이라고 추정할 수 있다(S114). Therefore, if the average vibration value is less than the first reference value, it can be estimated that the noise is generated by the actual sound (S114).

만약, 평균 진동값이 제1 기준값 이상이면, 실내환경 플랫폼(100)은 진동센서신호를 주파수 영역(frequency domain)에서 분석하여 100Hz 미만의 대역폭에 대한 파워값을 구한다(S116).If the average vibration value is equal to or greater than the first reference value, the indoor environment platform 100 analyzes the vibration sensor signal in a frequency domain to obtain a power value for a bandwidth of less than 100 Hz (S116).

도 6은 진동센서신호를 주파수 영역에서 분석한 것을 나타낸 것이다. 6 shows the analysis of the vibration sensor signal in the frequency domain.

도 6을 참조하면, 진동 주파수(Hz)를 푸리에 변환(FFT)하여 주파수에 따른 파워값을 확인할 수 있다. 도 6에서, 도면부호 1이 가리키는 파워값을 확인함으로써 외부 충격이 발생했다는 것을 알 수 있다. Referring to FIG. 6 , a power value according to a frequency may be checked by performing a Fourier transform (FFT) on a vibration frequency (Hz). In FIG. 6 , it can be seen that an external shock has occurred by checking the power value indicated by reference numeral 1 .

실내환경 플랫폼(100)은 2차 진동 분석 단계(S116)에서 산출한 파워값을 제2 기준값과 비교한다(S118). 파워값이 제2 기준값 미만이면, 소음이 바람 등의 외부인자에 의해 발생한 것이라고 추정할 수 있다(S122). The indoor environment platform 100 compares the power value calculated in the secondary vibration analysis step (S116) with a second reference value (S118). If the power value is less than the second reference value, it can be estimated that the noise is generated by an external factor such as wind (S122).

만약, 파워값이 제2 기준값 이상이면, 소음이 충격에 의해 발생한 것이라고 추정하고 이 경우 소음의 원인을 층간 소음으로 판정할 수 있다(S120).If the power value is equal to or greater than the second reference value, it is estimated that the noise is generated by an impact, and in this case, the cause of the noise may be determined as inter-floor noise (S120).

본 발명의 실시예에서는 실내환경 모니터링에 대해 상술하였으나, 이에 한정되는 것은 아니며, 통합 환경센서 모듈의 설치 위치에 따라 유리창 모니터링, 현관문 모니터링, 실내활동 모니터링 등과 같은 다양한 모니터링을 수행할 수 있다. In the embodiment of the present invention, although the indoor environment monitoring has been described above, the present invention is not limited thereto, and various monitoring such as window monitoring, front door monitoring, indoor activity monitoring, etc. may be performed depending on the installation location of the integrated environmental sensor module.

실내환경 인자로서 실내환경 모니터링에서는 온도, 습도, 미세먼지, 소음 및 진동이 적용되는 반면, 유리창 모니터링에서는 온도 또는 진동이 적용되고, 현관문 모니터링에서는 진동이 적용되고, 실내활동 모니터링에서는 소음 및 진동이 적용될 수 있다.As indoor environmental factors, temperature, humidity, fine dust, noise and vibration are applied in indoor environment monitoring, while temperature or vibration is applied in window monitoring, vibration is applied in door monitoring, and noise and vibration are applied in indoor activity monitoring. can be applied.

실내환경 모니터링에서는 통합 환경지수나 미세먼지농도, 소음레벨 등에 근거해 실내환경 상태의 이상을 경고하고, 유리창 모니터링에서는 온도값이나 진동세기에 근거해 유리창 파손, 침입 또는 결로 등을 경고하고, 현관문 모니터링에서는 진동세기에 근거해 현관문 충격이나 침입 등을 경고하고, 실내활동 모니터링에서는 소음레벨이나 진동세기에 근거해 낙상이나 쓰러짐 등 사용자 활동의 이상을 경고할 수 있다. Indoor environment monitoring warns of abnormalities in the indoor environment based on the integrated environmental index, fine dust concentration, and noise level. In monitoring, shock or intrusion of the front door is warned based on the intensity of vibration, and in indoor activity monitoring, abnormalities in user activity such as a fall or collapse can be warned based on the noise level or intensity of vibration.

The jig 30 is a part for fixing the sensor box 40 . The user first installs the jig 30 at a location where the integrated environmental sensor module is to be installed, and then fixes the sensor box 40 to the jig 30 .
