Indoor fire alarm and evacuation method

Abstract

The invention discloses an indoor fire alarm and evacuation method. The method comprises the steps of receiving an alarm triggering command sent by an alarm node; sending a wake-up command to all alarm nodes to make all the alarm nodes immediately send detection information to a server in real time; obtaining real-time weight information of all indoor routes according to the real-time detection information; receiving real-time location information of a mobile end; generating a real-time optimal evacuation route from a real-time location to any entrance according to normal-state weight information and the real-time weight information, namely an indoor route with the real-time maximal sum of normal-state weight and real-time weight from the real-time location to any entrance; sending the optimal evacuation route to the mobile end in real time according to ID information of the mobile end. Thus, through the adoption of the indoor fire alarm and evacuation method, the provided evacuation route is not only shortest but also safest; compared with local algorithms used in existing evacuation methods, an algorithm of real-time path planning is adopted, complex and changeable fire conditions can be adapted, the practicability is higher, and the efficiency of fire evacuation can be improved.

Description

technical field [0001] The invention relates to the technical field of fire alarm monitoring, in particular to an indoor fire evacuation method. Background technique [0002] Existing fire safety evacuation mostly guides the masses to carry out fire safety evacuation by fire emergency lighting and evacuation indicator signs. However, in reality, affected by factors such as personnel distribution, terrain changes during fires, and fire conditions, it is often difficult to achieve safe and efficient evacuation according to the evacuation methods indicated by signs, and it is easy to cause crowds to gather and cause danger. [0003] In order to solve the above problems, there is currently an algorithm that uses the shortest path algorithm to calculate the escape route for each person in a different location. Generally, local calculation is used, and the real-time performance is poor. The escape route obtained is the shortest, but not necessarily Do the safe path. Moreover, th...

However, in reality, affected by factors such as personnel distribution, terrain changes during fires, and fire conditions, it is often difficult to achieve safe and efficient evacuation according to the evacuation methods indicated by signs, and it is easy to cause crowds to gather and cause danger.

[0003] In order to solve the above problems, there is currently an algorithm that uses the shortest path algorithm to calculate the escape route for each person in a different location. Generally, local calculation is used, and the real-time performance is poor. The escape route obtained is the shortest, but not necessarily make safe path

Moreover, this algorithm guides people to escape to the entrance and exit, and it is easy to cause a stampede hazard when the flow of people is large.

Therefore, this algorithm is not practical for fire evacuation
