System for automatically and intelligently generating emergency evacuation scheme in real time

Abstract

The invention belongs to the technical field of evacuation indication, and more particularly relates to a system for automatically and intelligently generating an emergency evacuation scheme in real time. An alarm detector, an evacuation indicator lamp and a virtual intersection node are arranged and used as route nodes, a route database is formed by initializing all through routes, the route database is used as a reference standard tool for calculating and generating the shortest escape route according to the principle of getting away from a fire source and getting close to an exit, the imaged node connection manner is adopted, what you see is what you get, and a basic route database is directly constructed and generated. By means of the system, the evacuation scheme is automatically generated in real time when multiple points give out alarms at the same time or different times, and the system evacuation processing capacity under the complex fire disaster environment is improved; the fire disaster / smoke spreading trend analysis and evacuation coping strategy is achieved, and the fire disaster development judging and commanding capacity is improved; and the system installation, generation and test workloads are remarkably reduced, and the work efficiency is greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of evacuation instructions, and more specifically, relates to a real-time automatic intelligent generation system for an emergency evacuation plan. Background technique [0002] With the development of the economy, there are more and more complex and multifunctional buildings, especially the over-standard buildings such as large shopping malls. When a fire occurs, it is particularly important to evacuate people. More and more places are beginning to use intelligent evacuation systems that can automatically change the evacuation direction according to the actual situation to replace the single-direction evacuation sign, so that people can quickly and correctly evacuate. Buildings that choose intelligent evacuation have the characteristics of large and complex space, many passages and exits but not clear at a glance, which often makes the escape crowd confused in panic. At present, all intelligent evacuation syste...

AI Technical Summary

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 plans 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 plans must be designed, and it is difficult for an experienced engineer team to do it, even if they spend a long time
