Problems solved by technology

[0003] 1. The traditional pre-plan evacuation method, that is, "nearby guidance", this evacuation method can play an emergency evacuation role for simple and miniaturized buildings, but in practice, the fire spread trend is constantly changing, and the evacuation path remains unchanged. It may cause the escape personnel to stray into the dangerous area filled with smoke, which will bring greater danger to the escape personnel
[0004] 2. A new real-time evacuation method, that is, "intelligent evacuation", mainly uses vector graphics or building simulation GIS information calculations. The system calculates the shortest evacuation path to the safety exit according to the fire alarm source. This evacuation method can be quickly calculated according to the actual situation. Evacuation routes, but the core is still "nearby guidance". It is more effective when the number of people in the building is small or the function of the building structure is relatively single. It brings secondary disasters such as congestion and stampede, which is not conducive to rapid evacuation

Embodiment 1

[0024] Embodiments of the present invention provide a method for determining evacuation routes for complex buildings with congestion and trampled on, such as figure 1 shown, including the following steps:

[0025] Step S101: Determine the distribution of alarm areas where alarms occur on the current floor.

[0026] In this embodiment, the alarm area refers to the part of the space where the warning range of the automatic fire alarm system is divided according to the fire protection zone or floor in the design, and is the basic unit for setting up the area fire alarm controller; the distribution of the area can be determined to determine the coverage of dangerous situations range, so that the specific evacuation route can be determined later based on the real-time coverage.

[0027] Step S102: Determine the available evacuation routes for each alarm area according to the distribution and the preset evacuation route usage rules.

[0028] In this embodiment, when the building i...

Embodiment 2

[0033] An embodiment of the present invention provides a method for determining an evacuation route for a complex building that prevents congestion and stampede. The aforementioned method includes the following steps:

[0034] Step S201:

[0035] Obtain the alarm position of the alarm area where the alarm occurs on the current floor;

[0036] According to the location of the alarm, the distribution map of the alarm area where the alarm occurs in the current floor is generated.

[0037] Step S202:

[0038] According to the distribution map, judge whether all the evacuation routes reserved for the alarm area during construction pass through another alarm area;

[0039] If there is another alarm area where an alarm occurs, all the reserved evacuation routes except those that pass through another alarm area where an alarm occurs are available evacuation routes; if there is no access to another alarm area where an alarm occurs, All reserved evacuation routes are available.

Embodiment 3

[0065] Embodiments of the present invention provide an evacuation path determination system for complex buildings that prevent congestion and stampede, such as Figure 4 shown, including:

[0066] The first determination unit 30 is configured to determine the distribution of alarm areas where alarms occur on the current floor;

[0067] The second determination unit 31 is configured to determine the available evacuation routes for each alarm area according to distribution conditions and preset evacuation route usage rules;

[0068] The third determination unit 32 is configured to determine the recommended evacuation route for each alarm area according to the distribution, the length of the available evacuation routes, the evacuation capacity of the available evacuation routes, the evacuation requirements of each alarm area and preset route recommendation rules.

[0069] Wherein, the first determining unit 30 is specifically used for:

[0070] Obtain the alarm position of the ...

Abstract

The invention relates to an evacuation path determination method and system for a complex building for preventing secondary disasters. The method specifically comprises the following steps: determining the distribution condition of alarm areas with alarms in a current floor; further, according to the distribution condition and a preset evacuation path use rule, determining an available evacuation path of each alarm area; and furthermore, according to the distribution condition, the length of the available evacuation path, the evacuation capability of the available evacuation path, the evacuation demand of each alarm area and a preset path recommendation rule, determining a recommended evacuation path of each alarm area. According to the method, factors such as evacuation capacity, evacuation demands and the length of an evacuation path in an actual scene are comprehensively considered, effective shunt evacuation is achieved, risks of secondary disasters such as personnel gathering and crowding stampede are greatly reduced, evacuation and escape instructions of all stages of a fire scene are effectively responded, intelligent evacuation is truly achieved, and the life and property safety of people is powerfully guaranteed.

Description

technical field [0001] The invention relates to the technical field of emergency evacuation, more specifically, to a method and system for determining an evacuation path for a complex building for preventing secondary disasters. Background technique [0002] A complex building is a building composed of multiple functional spaces, which has the characteristics of large area, complex structure, and accommodating many people. Therefore, when a fire occurs, how to quickly and orderly evacuate the people in the building is a key problem to be solved in modern building fire protection. Currently, the mainstream solutions to the aforementioned problems are as follows: [0003] 1. The traditional pre-plan evacuation method, that is, "nearby guidance", this evacuation method can play an emergency evacuation role for simple and miniaturized buildings, but in practice, the fire spread trend is constantly changing, and the evacuation path remains unchanged. It may cause the escape per...
