| description | The invention relates to a fire disaster early warning method and system. The fire disaster early warning method includes the steps that S1, the fault state of fire extinguishment equipment and the fault state of evacuation equipment in the environment are monitored in real time; S2, the crowd density in the environment is obtained, the successful crowd evacuation probability when a fire disaster occurs is simulated according to the fault state of the fire extinguishment equipment, the fault state of the evacuation equipment and the crowd density; and S3, whether the successful evacuation probability is smaller than a preset probability or not is determined, and if the successful evacuation probability is smaller than the preset probability, fire disaster early warning information is automatically sent. By means of the technical scheme, the crowd escape probability can be determined before the fire disaster occurs, the early warning information is sent in advance, and preventive measures such as measures for limiting people number, opening more entrance and exit passages and the like can be carried out; the problem that people cannot escape timely and casualties are caused when the fire disaster occurs can be avoided; besides, the shortest way can be provided for crowd evacuation, and the people can rapidly escape from the dangerous situation. |
