An escape training method and system for an expanded tobacco shredding section

Abstract

The invention discloses an escape training method for an expanded tobacco shredding section, which comprises the following steps of: establishing a three-dimensional scene diagram according to the actual scene of the expanded tobacco shredding section; generating generate multiple escape paths by taking doorway, staircase, corridor turning and fork in three-dimensional scene graph as nodes, whichconstitute the set of escape paths G (N, A), and the optimization model of the optimal escape paths is established; when searching for the optimal escape route, introducing ant algorithm, take high temperature into account, toxic gas, when it comes to risk factors such as oxygen and smoke, Under the constraints of pheromone concentration and transition probability threshold, finding the shortest path output in the set of escape paths, the shortest path being the optimal escape path, so the escape path obtained has a strong guiding significance. The escape path has a certain degree of protection for the escape effect, that is to say, can ensure the escapee to escape from the accident scene safely according to the escape path.

Description

technical field [0001] The invention belongs to the technical field of disaster escape, and in particular relates to an escape training method and system for an expanded cut tobacco section. Background technique [0002] Expanded shredded tobacco refers to shredded tobacco made from tobacco leaves that have been modulated and redried, and shredded tobacco that has been expanded through the shredded tobacco expansion process. Cut tobacco expansion can be divided into full formula expansion and partial expansion. Partial expansion can also be called off-line expansion. It is to add some kind of medium to part of the cut tobacco used in cigarettes and then perform high temperature treatment. Partial expansion of cut tobacco can achieve higher than full formula expansion. fill value. [0003] The expanded cut tobacco section is a section for expanding the cut tobacco, and it is a special part of the shredded tobacco workshop. Due to the existence of combustion furnaces, a larg...

Problems solved by technology

Although this method can notify people to escape according to the generated path when there is danger, it does not consider the impact of many factors in the escape process on the escaped personnel, so the guidance effect of the escape route on the escaped personnel is unpredictable.
