Abstract: The present invention relates to a control and security method for an intelligent earthquake disaster prevention system. According to the present invention, a facility is controlled by interworking with a regional control information processing device when the facility is controlled during an earthquake. As a result, the facility can be protected. During the control, a P wave is measured and detected from an earthquake measuring device. During the measurement, whether the earthquake is a direct earthquake is confirmed based on whether the magnitude of the vibration of the measured P wave is equal to or greater than a preset and predetermined magnitude. Then, the facility is directly controlled in the case of a direct earthquake. Otherwise, the facility is controlled in accordance with a control signal of the regional control information processing device. During the control signal-based control, the execution or non-execution of real-time control is checked by blockchain generation and sharing of the execution or non-execution. A transaction toward a related information processing device grouped and preset so as to control the facility during an earthquake is performed at each blockchain generation. In addition, authentication is given from a pre-registered authentication information processing device and the facility control is actually initiated and performed. During the intelligent earthquake disaster prevention control based thereon, blocking of the control by a malicious external user is prevented and a distributed ledger is applied such that the controlling user and element can be managed transparently.
