PURPOSE: A disaster-prevention system having diagnosis and correction function and a method thereof are provided to enable disaster-prevention sensors to operate always normally by checking operation states of disaster-prevention sensors. CONSTITUTION: The disaster-prevention system includes at least more than one disaster-prevention sensors(11,12,13) sensing emergency, and a control part(22). The control part diagnoses abnormal operation of the disaster-prevention sensor as monitoring the operation state of the disaster-prevention sensor, and changes an operation initial value of the sensor when an abnormal operation of the disaster-prevention sensor is generated. The disaster-prevention sensor changes its operation initial value according to the control of the control part, and operates at the changed operation initial value. An alarm part(23) generates an emergency alarm when measurement data from the sensor is above a warning value. |
