Emergency evacuation automatic intelligent generation system

Abstract

The invention belongs to the technical field of evacuation indication, and relates to an emergency evacuation automatic intelligent generation system. The system comprises an alarm detector, an evacuation indication lamp, and a virtual intersection node. By initializing all through paths, a path database is formed, the path database is taken as a basis reference tool for calculating and generating a shortest escape path according to a keep-away-from-fire and nearby exit evacuation principle, a basic path database is directly established and generated, and the alarm detector and the evacuation indication lamp are set as path nodes. All the through paths are initialized to form the path database; the shortest escape path is calculated and generated according to the keep-away-from-fire and nearby exit evacuation principle; an evacuation scheme generated in real time is written in the database for the system to call and the evacuation indication lamp is driven to be turned on or off directionally; and an alarm event and the evacuation scheme are stored as logs for postmortem analysis. According to the system, the evacuation design command difficulty of a complex fire scene can be lowered, the correctness of an evacuation indication direction is ensured, and intelligent evacuation is more stable and safer.

Description

technical field [0001] The invention belongs to the technical field of evacuation instructions, and more specifically relates to an automatic intelligent generation system for emergency evacuation. Background technique [0002] With the development of the economy, there are more and more complex and multi-functional buildings, especially super-standard buildings such as large shopping malls. When a fire breaks out, evacuation and escape of personnel is particularly important. More and more places are beginning to replace single-directional evacuation signs with intelligent evacuation systems that can automatically change the evacuation direction according to actual conditions, so that people can evacuate quickly and correctly. Buildings that choose intelligent evacuation have the characteristics of large and complex spaces, many passages and exits that cannot be seen at a glance, and often make the escaped crowd confused in panic. At present, each intelligent evacuation sys...

Problems solved by technology

At present, each intelligent evacuation system prepares the evacuation route in advance in the form of a plan, but due to the large volume of the building and the many alarm points, it is impossible to exhaust all possible plans. Generally, only a single alarm point is considered, let alone multi-point alarm or fire spread. Situational evacuation command greatly reduces the practicability of intelligent evacuation

[0003] Taking a project with 100 independent alarm points as an example, only considering the evacuation plan of one alarm point at the same time, it is necessary to design 100 sets of plans, which can be done by engineers with certain experience; at the same time, considering the evacuation plan of any two alarm points, according to Combination algorithm, C(100, 2) = 4950, that is to say, 4950 sets of schemes must be designed. A team of engineers with certain experience may be able to do it, but it will take a long time; at the same time, consider the evacuation plan of any three alarm points, according to the combination Algorithm, C(100, 3) = 161700, that is, 161700 sets of schemes must be designed, which is difficult for an experienced engineer team, even if they spend a long time
