Earthquake monitoring sensor and earthquake monitoring system including the same

摘要

An earthquake monitoring sensor based on an asymmetrical shape of facilities and an earthquake monitoring system including the same. The earthquake monitoring sensor is provided to facilities having an asymmetrical shape vulnerable to an earthquake and provides a rapid earthquake response with regard to an earthquake-vulnerable direction of the facilities, thereby enabling establishment of effective countermeasures to the earthquake. The earthquake monitoring sensor for facilities includes a north-to-south component vibration measuring device sensing a north-to-south direction vibration signal; and an east-to-west component vibration measuring device sensing an east-to-west direction vibration signal, wherein a vibration signal sensing direction of one of the north-to-south component vibration measuring device and the east-to-west component vibration measuring device is set to match a vulnerable direction of corresponding facilities, and monitoring data output from the vibration measuring device set to match the vulnerable direction is provided as vulnerable direction data of the corresponding facilities.
