In recent years, there are a number of human casualties due to occurrence of a large-scale earthquake in many countries, including Korea, China, and Japan, and many buildings are collapsing.
In particular, in the Republic of Korea, there is a trend that medium to minor-earthquake regions or the number of earthquake occurrence times continuously increases in respect to occurrence of an earthquake and a 5.8-scale earthquake occurs in Gyeongju in 2016, and as a result, it is determined that the Republic of Korea is no longer a safe zone against the earthquake.
Damage at the time of the occurrence of the earthquake is divided into primary damage which occurs due to a primary earthquake and secondary damage such as leakage of gas, a short circuit, breakage of a water supply and drainage pipe, etc., due to the earthquake.
In particular, in the Republic of Korea, a heated floor system, called ondol culture utilizing a boiler is developed in Korea, and the boiler is installed every household.
Since the boiler uses a highly flammable substance such as oil and gas as fuel, there is a risk that human and property damage can be increased during leakage of the fuel due to the earthquake, etc.
Accordingly, there is a demand for a countermeasure against a secondary safety accident of the boiler due to the fuel leakage or overheat during occurrence of flow and vibration of the boiler due to a natural disaster such as the earthquake, etc.
As such a demand, it is configured in such a manner that a gas detector and an earthquake detector for detecting leaked gas are installed on a periphery on which the gas is used, such as the boiler, a gas range, etc., and the occurrence of the earthquake and the leakage of the gas are detected and the resulting alarm is generated, but there is a problem in that general persons cannot take an appropriate measure against the gas leakage and the earthquake due to a failure of an alarm device, an easy response to the alarm, etc.
Therefore, required is development of a remote monitoring system for gas leakage and occurrence of the earthquake, in which in addition to the detection of the gas leakage and the earthquake, the gas leakage can be quickly notified to a user regardless of a location of the user, and even though the user detects the gas leakage, a remote manager performing 24-hour monitoring can monitor the gas leakage in a house and the occurrence of the earthquake and notify the gas leakage and the occurrence of the earthquake to the user, and quickly cope with the gas leakage and the occurrence of the earthquake.

The detector control unit 170 acquires the acceleration sampling data through the earthquake detection unit 152 and calculates an acceleration for each axis from the acquired acceleration sampling data (S313).
When the gas measurement data and the acceleration for each axis are calculated, the detector control unit 170 examines a gas measurement value according to a gas type, i.e., a gas concentration value exceeds a threshold (reference value) predefined for the corresponding gas type (S315), and examines whether the acceleration value for each axis exceeds a threshold (reference value) of a corresponding axis (S317).
When either the gas measurement value and the acceleration value do not exceed the reference values, the detector control unit 170 generates the gas state monitoring information including the gas measurement data and the acceleration sampling data, and transmits the generated gas state monitoring information to the detector management unit 30 (S337).
On the contrary, when the gas measurement value exceeds the threshold, the detector control unit 170 counts a gas detection time (S319), monitors whether the gas detection time is continued for a predetermined time or more (S321) and when there is an acceleration value for each axis, which exceeds the threshold among the acceleration values for each axis, the detector control unit 170 starts counting a vibration time (S327) and monitors whether the vibration is continued for a predetermined time (S329).
When the gas detection time is continued for a predetermined time or more, the detector control unit 170 generates the alarm notification information and transmits the generated alarm notification information to at least one of the detector management unit 30 and the user mobile terminal 50 (S323), and autonomously generates the alarm through the alarm generation unit 160 (S325).

After the alarm is generated, the detector control unit 170 controls the switch unit 190 interrupts external power to the detector target device 10 (S339).
On the contrary, when the gas detection time is not continued for the predetermined time or more or the vibration time is not continued for the predetermined time or more, the counted time is initialized (S335) and the process returns to repeatedly perform the above-described process.
