Abstract

The invention discloses a fire-fighting, fire-extinguishing and rescue intelligent path planning method and system. The method comprises the following steps: establishing a road hierarchical structuremodel by taking road properties, road specifications and traffic information as influence factors; determining a weight vector of each influence factor in the road hierarchical structure model by adopting an analytic hierarchy process; constructing a road network directed graph, obtaining a current starting point position, a terminal point position and real-time road condition information in realtime, and calculating a time-varying weight value of each road section in combination with the weight vector of each influence factor; and performing real-time path planning by taking the shortest time as a decision-making target based on the time-varying weight of each road section. According to the invention, the vehicle can actively avoid coherent road sections, and then time optimal path planning is performed based on the time-varying weight of each road section, thereby ensuring that the fire-fighting vehicle arrives at a fire scene in time.

Description

technical field [0001] The invention belongs to the technical field of intelligent fire protection, and in particular relates to an intelligent path planning method and system for fire fighting and rescue. Background technique [0002] With the rapid expansion of the city, the frequency of various types of fires has gradually increased, which directly threatens the safety of people's lives and property. As a social security force, fire rescue is very important to be able to arrive at the fire scene in time to carry out rescue. [0003] Existing fire rescue is mostly based on the shortest distance path planning, however, factors such as unknown real-time traffic conditions and possible traffic jams seriously restrict the speed of fire fighting and rescue. Although the existing time-based path planning speeds up the rescue to a certain extent, it still does not fully consider the real-time changes in traffic conditions, and cannot cope with various emergencies, delaying rescu...
