Fire protection method and fire protection system

A fire protection system comprising:

• a plurality of sensors having different address values, configured to detect fire occurrence, generate a fire alarm, and perform Radio Frequency (RF) communication with each other;
• a first server configured to perform RF communication with each of the plurality of sensors;
• and
• a second server configured to receive external data from an external server and communicate with the first server,
• wherein the second server comprises:
• a data collection unit configured to collect sensor data measured by each of the plurality of sensors and the external data;
• a data extraction unit configured to extract fire data based on information collected by the data collection unit;
• and
• a complex event processing unit configured to process a complex event based on the fire data and to output mutually different fire evaluation criteria by space, use, and fuel type based on the fire data,
• a guide unit configured to output mutually different fire occurrence probabilities by space, use, and fuel type based on the fire evaluation criteria and the information collected by the data collection unit;
• and
• a simulation unit configured to receive the mutually different fire occurrence probabilities by space, use, and fuel type from the guide unit and simulate and output a virtual 3D plant facility model responsive to receiving the mutually different fire occurrence probabilities by space, use, and fuel type,
• wherein the guide unit is further configured to output a preliminary warning message to the simulation unit when the fire occurrence probability is equal to or greater than a predetermined value, and
• the simulation unit is further configured to detect a fire risk based on the virtual 3D plant facility model.
