An emergency evacuation guidance method for subway stations

Abstract

The present invention relates to an emergency evacuation guidance method for subway stations, comprising: Step S1: Divide the subway station platform into several evacuation areas with the evacuation exits of the station platform as the boundaries; Step S2: Set up an interaction device in the station control room, set up an exit guidance terminal at the evacuation exits of the station platform, and set up several area guidance terminals in each evacuation area; Step S3: The interaction device receives the disaster location information and dynamically calculates the working modes of each exit guidance terminal and area guidance terminal; Step S4: Each exit guidance terminal and area guidance terminal receive the working modes issued by the interaction device and display images of different light colors. Compared with the prior art, the present invention can be applicable to all evacuation scenarios of subway stations, provide a refined evacuation guidance plan based on the disaster location, and improve the emergency evacuation efficiency of the station and the survival rate of passengers.

Claims

1. An emergency evacuation guidance method for subway stations, characterized in that, the method includes the following steps: Step S1: Divide the station platform into several evacuation areas with the evacuation exits of the station platform as the boundaries; Step S2: Set an interaction device in the station control room, set several exit guidance terminals at the evacuation exits of the station platform, and set several area guidance terminals in each evacuation area; Step S3: The interaction device receives the disaster location information and dynamically calculates the working modes of each exit guidance terminal and area guidance terminal; Step S4: Each exit guidance terminal and area guidance terminal receive the working modes issued by the interaction device and display images of different light colors; The dynamic calculation method in the said Step S3 specifically includes: Step S31: Judge the evacuation area where the disaster location is located and mark it; Step S32: Calculate the working modes of each exit guidance terminal; Step S33: Calculate the working modes of each area guidance terminal in the marked evacuation area; Step S34: Calculate the working modes of each area guidance terminal in the unmarked evacuation area; The said Step S32 specifically includes: Step S321: Calculate the distance SE between the disaster location and the exit guidance terminal; Step S322: If SE ≤ the first threshold, set the working mode of this exit guidance terminal as "dangerous", if SE is between the first threshold and the second threshold, set the working mode of this exit guidance terminal as "undetermined", if SE ≥ the second threshold, set the working mode of this exit guidance terminal as "safe"; The said Step S33 specifically includes: Step S331: Calculate the distance SR between the disaster location and the area guidance terminal; Step S332: Calculate the distance between the area guidance terminal and the evacuation exit and the distance between the disaster location and the evacuation exit, and calculate the difference DE between the two; Step S333: If SR ≤ the first threshold, set the working mode of this area guidance terminal as "dangerous", otherwise, if DE ≥ 0, set the working mode of this area guidance terminal as "undetermined", if DE < 0, set the working mode of this area guidance terminal as "positive indication"; The said Step S34 specifically includes: Step S341: Judge the working mode of the exit guidance terminal corresponding to this evacuation area; Step S342: If the working mode of the exit guidance terminal is "dangerous", set the working mode of the corresponding area guidance terminal as "reverse indication", if the working mode of the exit guidance terminal is "undetermined", set the working mode of the corresponding area guidance terminal as "undetermined", if the working mode of the exit guidance terminal is "safe", set the working mode of the corresponding area guidance terminal as "positive indication".

2. The emergency evacuation guidance method for subway stations according to claim 1, characterized in that, each of the evacuation areas divided in the said Step S1 has and only has one evacuation exit.

3. The emergency evacuation guidance method for subway stations according to claim 1, characterized in that, The light color images shown in the step S4 include three static images of red, black, and green, corresponding to three working modes of "Danger", "Undetermined", and "Safe", respectively, and two dynamic images of forward indication and reverse indication, corresponding to two working modes of "Forward Indication" and "Reverse Indication", respectively. Among them, the forward indication image is defined as a dynamic image pointing to the direction of the evacuation exit, and the reverse indication image is defined as a dynamic image facing away from the direction of the evacuation exit.
