1. A management system apparatus for performing determination of a risk situation in an indoor space, which includes a passive infrared human body detection sensor for detecting a human object present in the indoor space, a temperature sensor, a humidity sensor, a fine dust detection sensor, a carbon dioxide detection sensor, a smoke sensor, and a motion detection sensor, comprising:
a first determination event generation unit generating a first determination event for determining whether a risk situation is present exists in the indoor space at a predetermined determination cycle interval;
when the first determination event is generated, an acquisition unit checking whether the human object is detected in the indoor space through the passive infrared human body detection sensor, and when it is confirmed that the human object is detected as a result of the checking, acquires n, wherein n is a natural number of 2 or more, temperature measurement values, n humidity measurement values, n fine dust measurement values, n carbon dioxide measurement values, and n smoke measurement values measured continuously through the temperature sensor, the humidity sensor, the fine dust detection sensor, the carbon dioxide detection sensor, and the smoke sensor at the predetermined measurement cycle interval, and at the same time, acquiring n discrimination values related to whether motions measured continuously through the motion detection sensor at the measurement cycle interval are detected;
a score generation unit generating a first score representing an indoor discomfort level for the indoor space based on the n temperature measurement values and the n humidity measurement values, generating a second score representing an indoor pollution level for the indoor space based on the n fine dust measurement values and the n carbon dioxide measurement values, generating a third score representing a fire risk level in the indoor space based on the n smoke measurement values, and generating a fourth score for discriminating whether the motion of the human object is abnormal based on the n discrimination values; and
a notification transmission unit transmitting a first notification message indicating that the indoor discomfort level in the indoor space is high to a predetermined guardian terminal when the first score is more than a predetermined first reference value, transmitting a second notification message indicating that an indoor pollution level in the indoor space is high to the guardian terminal when the second score is more than a predetermined second reference value, transmitting a third notification message indicating that there is a fire risk in the indoor space to the guardian terminal when the third score is more than a predetermined third reference value, and transmitting a fourth notification message indicating that the motion of the human object is abnormal to the guardian terminal when the fourth score is more than a predetermined fourth reference value to notify that there is the risk situation in the indoor space.
