Description

Damage monitoring system for infrastructure facilities {MONITORING SYSTEM FOR DAMAGE OF INFRASTRUCTURE FACILITY}

The present invention relates to a facility monitoring system, and more particularly, to a system for monitoring a damage situation of an environmental facility in the event of a disaster.

In general, when an earthquake occurs, an alert is issued to equipment and people in the area where the seismic wave is expected to reach through the national integrated seismic observation network. Accordingly, in environmental facilities such as water purification facilities and sewage facilities among national infrastructure facilities, personnel are evacuated to minimize human damage according to the early earthquake warning, and in order to minimize damage to the facilities, the operation of the facilities is stopped or according to the response manual operate

In addition, at the conclusion of an earthquake, personnel are dispatched promptly to determine damage recovery or the system is inspected to evaluate the damage condition and then repair or restart the facility. As described above, until now, there is no technology capable of monitoring in real time except for post-evaluation of the damage situation of environmental facilities in the event of an earthquake.

However, if information on damage to a facility cannot be obtained during an earthquake, there is a risk that the facility may malfunction or stop operation due to the situation dependent on manpower. In addition, when facility operation is stopped due to earthquake damage, environmental facilities take a lot of time to identify and analyze the damage situation and make a decision, and it takes a lot of time until restarting.

For this reason, it is difficult to produce water for a long time, which may cause a water cut, and in the case of a sewage treatment plant, it is difficult to treat influent water, so there is a fear that the contaminated water is discharged into the water system as it is, causing water pollution.

In addition, analysis takes a long time due to the analysis based on manpower, and the subjective opinion of the inspector is reflected in the evaluation result, so that the degree of damage to the facility cannot be accurately confirmed.
