The control unit 154 determines whether the vibration transmitted to the enclosure main body 110 is generated in the enclosure main body 110 or externally in response to the comparison result in the comparing unit 153.

The control unit 154 regards the data supplied from the master module 150, the slave module 140 and the reference module 130 as an abnormal vibration when an external force equal to or greater than the vibration magnitude set for example as an earthquake is applied The power supply to the inside of the enclosure main body 110 may be shut off.

Since the master module 150, the slave module 140, and the reference module 130 can detect the magnitude of an external force such as vibration, the controller 154 determines the presence or absence of vibration, Unlike measures that are taken after measurement, even if it is the first vibration, it provides a detection function that can take action such as power off immediately if an external force exceeding the set size is detected.

The master module 150 includes a three-axis vibration accelerometer for measuring vibration and tilt, a gyroscope sensor, and a zero setting device for adjusting a zero point.

The slave module 140 is equipped with a three-axis vibration accelerometer for measuring vibration and tilt, a gyroscope sensor, and a zero point setting device for adjusting the zero point. In addition, the slave module 140 has a built-in communication function for transmitting data to the master module 150.

Therefore, it is possible to check the vibration absorption state of the anti-vibration member constituting the seismic facility 120 by comparing the vibration value measured by the master module 150 and the slave module 140 with the vibration value measured by the reference module 130 , The deterioration state and the service life of the seismic equipments 120 can be grasped by analyzing the vibration and the slope trend with time.

In the case of an external vibration including an earthquake, a relatively large vibration is measured in the master module 150 and a relatively small vibration is measured in the slave module 140. When the installation position of the master module 150 and the slave module 140 The intensity of the vibration can be varied.

However, when vibration occurs in the enclosure main body itself due to the impact of the breaker on / off, the vibration is directly applied to the master module 150 and the slave module 140, so that a large vibration value is measured. On the other hand, Because it is difficult to measure in position, values close to '0' are measured.

Therefore, when the vibration magnitudes of the master module 150, the slave module 140, and the reference module 130 are compared, it is possible to grasp the source of the vibration and to eliminate an error due to vibration generated in the enclosure main body.

Also, the tilt of the enclosure main body 110 is measured using the master module 150 and the slave module 140, which can also be used when installing the enclosure main body 110. When vibration is continuously applied to the seismic equipments 120, the seismic equipments 120 are deteriorated and the enclosure bodies 110 are inclined. Therefore, the master module 150 and the slave module 140 measure the slope of the enclosure main body 110, and when a slope of more than a certain level occurs, the master module 150 outputs a trip signal through the master module 150, The life of the seismic equipment can be analyzed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
